Yeast genomic DNA isolation

C. glabratastrains were routinely grown in rich YPD medium or synthetically defined YNB medium, or YNB medium supplemented with CAA, unlessstatedotherwise.To obtain overnight grown liquid cultures, C. glabratacells were inoculated in appropriate medium and incubated at 30°C under constant agitation (200 rpm) to maintain proper aeration.To revive the frozenstocks,about one tipfull of frozen culture was streaked either on YPD-agar or on CAA-agar medium. In general, frozen stocks of C. glabratastrains were revived on YPD-agar medium.However,C. glabratastrains harbouring plasmidscontainingURA3as a selectable marker were revived on CAA-agar medium. After streaking, plates were allowed to grow for 24-48 h at 30°C and were stored at 4°C for a maximum period of two weeks. For long term storage, freezer stocks of C. glabratastrainswere prepared in 15% glycerol and stored at -80° C.Escherichia colistrain DH5αwas revived on LB-agar medium from frozenstock and incubated at 37°C for 14-16 h. DH5α strainwas used for transformation purpose and maintaining plasmids. Bacterial strains harbouring plasmids containing selection markerswere revived on LB-agar medium supplemented with appropriate antibiotics.Bacterial liquid cultures were either grown in LB broth or LB broth containing suitable antibioticsand incubatedin a shakerincubator set at 37°C, 200 rpm for 14-16 h. For preparation of bacterial frozenstocks, 1 ml overnight grown bacterial culture was added to500 μl of 50% glycerolto obtain final concentration of ~16 % glyceroland stored at -80°Cuntil use

PMA-treated THP-1 cells were seeded toa24-well tissue culture plate to a cell density of 1 million cells per well and allowed to grow for 12 h. After12 hincubation,spent medium was replaced with fresh pre-warmed RPMI-1640 medium andcells were allowed to recover for 12 h before use.C. glabratacells were grown in YNB medium for 14-16 h at 30°C and 200 rpm. 1 ml of theseC. glabratacells were harvested in 1.5 ml centrifuge tubes, washed twice with 1X sterile PBS and the cell density was adjusted to 2x107cells/ml. 50 μl of this cell suspension was used for infection to a MOI of 1:1. Two hours post infection, wells were washed thricewith 1X sterile PBS to remove the non-phagocytosed yeast cells and 1 ml of fresh pre-warmed RPMI-1640 medium was added. Plates were incubated under tissue culture conditions at 37°C and 5% CO2for 24 h. Supernatants were collected in 1.5 ml microfuge tubes, centrifuged at 3,000 rpmto remove the particulate matter, if any, and stored at -20°C until use.

To perform survival analysis of C. glabratacells in macrophages, PMA-treated THP-1 cells were seeded to 24-well tissue culture platesto afinal celldensity of 1 millionper well. C. glabratacells were grown in YNB medium for 14-16 h at 30°C and 200 rpm. 1 mloftheseC. glabratacells were harvested in 1.5 ml centrifuge tubes, washed twice with 1X sterile PBS and the cell density was adjusted to 2x106cells/ml. 50 μl of this cell suspension was used to infect PMA-activated macrophages to a MOI (multiplicity of infection) of 0.1. Two hours post infection, THP-1 cells were washed thrice with 1X sterile PBS to remove the non-phagocytosed yeast cells and 1 ml of fresh pre-warmed complete RPMI-1640 medium was added.At different time points, infected THP-1 macrophages were osmolysed with1 ml sterile water. Post lysis,lysates were collected by scraping the wells using 1 ml microtip. Lysates were diluted in 1X sterile PBSand appropriate dilutions were plated onYPD-agar plates. Plates were incubated at 30°C for 24-48 h and colony forming units (CFUs) were counted. Final CFUs/ml were determined by multiplying CFUs withappropriate dilution factor and percentage phagocytosis was calculated by dividing CFUs obtained at 2 h post infection by total numberofyeast cells used for infection. Fold replication was calculated by dividing the CFUs obtained at 24 h post infection by CFUs obtained at 2 h post infection

Strains and plasmids

HEK293T packaging cellswere seeded at 30-40% confluency in 60 mm dishes. After 24 h, cells were co-transfected with three plasmids required for viral production i.e. VSV-G, psPAX2 (Addgene plasmid # 12260) and pLKO.1-puro-non-targeting and shIP6K1 clones using polyethyleniminereagent(PEI) and incubated at 37°C and 5% CO2 for virion formation.

Fresh overnight cultures grown in LB containing appropriate antibiotics to select for plasmids were sub-cultured 1:100(or lower dilutions for some strains)in the same medium. The cells from these cultures weretaken for microscopy at exponential phase of growth(A600 of 0.5-0.6), as such or after concentrating the cells 10-fold

Sample preparation

vii.RNA buffer II from Ambion(1-2X Xylene cyanol + Bromophenol blue)used for loading the samples. RNA isolation for Northern blotting for lacZtranscript was done aftergrowing cultures till A600of 0.6 in LB in the presence or absence of 1mM IPTG at 30oC while for lacZ-lacYʹ-tRNA(U73)Arg5or lacZʹ-tRNA(U73)Arg5transcripts, cultures were grown in LBupto A600of 0.3 and induced with 1mM IPTG for 30 min followed by RNA extraction.30ml of 10% polyacrylamide gels of 1.5mm thickness were cast in the Broviga slab vertical gel electrophoresis apparatus. Gels were polymerizedby the addition of TEMED and APS (1/100th volume of gel mix). The gel was pre-runat 300V for 15-20 minutes prior to loading.Sample preparation for gel loading was done as follows. The normalizedamounts of RNA samplesto be analyzed were mixed with the equal volumes of 2X gel loadingbuffer II(Ambion)making a final concentration of 1X. The samples were then heated at 80 degrees in a thermoblock (eppendorf) for 10 minutes and loaded on the gel when still warm. The gel was run at constant voltage of 300Vfor 3-4 hours till xylene cynol covered 2/3rddistance

The following solutions were used to cast and run denaturing PAGE gels:i.40% acrylamidestock solution ii.7.5M Ureaiii.5X TBEiv.Ammonium persulphate (APS) stock: 10% (w/v) solution made fresh v.TEMED (N,N,N′, N′-tetramethyl ethylene diamine) vi.Gel running buffer (0.5X TBE)

Denaturing polyacrylamide gel electrophoresis of RNA

For high fidelity PCR, Herculase II fusion DNA polymerase (AgilentTechnologies)was used. Approximately 0.5μg of chromosomal DNAwas used as a template in a 50μl reaction volume

The PCRs were normally performed using Taqpolymerasefrom Roche or Fermentas. Approximately 1-5ng of plasmid or 5-100ng of chromosomal DNA was used as a template in a50μlreaction volume containing 200μM of each dNTP, 20pM each of the forward and reverse primers and 1 unit of Taq DNA polymerase. For colony PCR E. coli cells from a freshly grown plate were resuspended in 10μl of sterile Milli-Q water to get a cell suspension and this was used as a template in a PCR reaction at a final volume of 50μl. The samples were typically subjected to 30 cycles of amplification with the following general conditions: Initial denaturation 95ºC5minutes Denaturation 95ºC 1 minute Annealing 55ºC 1 minute Extension 72ºC 1 minute/kb of DNA template to be amplified Final extension 72ºC 10 minutes

Polymerase Chain Reaction (PCR)

following the manufacturer’s instructions. For genomic DNA, 1ml culture was used for DNA isolationusing Qiagen or Invitrogen kits. The quality of plasmid/genomic DNApreparations was assessed following electrophoresis on 0.8% agarose gels

3ml (for high copy number)or 10 ml (for low-copy number) of cells from an overnight culture were pelleted by centrifuging for 5 minutes at 6000rpm forthe plasmid isolation which was carried out with the commercially available kits (Qiagen or Invitrogen)

Isolation of plasmid and chromosomal DNA

Growth curves were generated to compare the growth rates of E. coli test strains with control strains manually. The appropriate dilutions of the overnight cultures in desired media were made and allowed to grow at required temperature till faint turbidity was visible. At this point samples were collected every 30 minutes until stationary phase was attained. The growth curves weregenerated using Microsoft Excel or SigmaPlot software and growth rates were calculated from the slope of the graph which, in turn, was used to calculate generation time

Estimation of growth rates

β-Galactosidase assay was performed according to(Miller, 1992).Cultures were grown to A600 of 0.4-0.6 from a 1:100 dilution of overnight cultures. Around 0.1-0.5 ml of culture was made up to 1 ml with Z-buffer and lysed with the addition of 100μl of chloroform and 50μl of 0.01% SDS solution. 0.2ml of freshly prepared 4mg/ml ONPG was added to start the reaction and incubated at 28oCtill the colour of the reaction mixture turned yellow. 0.5ml of 1M Na2CO3 was added to stop the reaction and the time duration from initial addition of ONPG to the stopping of the reaction was noted. The absorbance of reaction mix was taken at 420 nm (A420) afterspinning down the mix at 12000rpm for 3 minutes. The A600of the culturesused was also noted. The enzyme’sspecific activity (in Miller units) was calculated using the following equation: β-Galactosidase specific activity (Miller units) = (1000 ×A420) / t × v ×A600Where,‘t’ is the time period in minutes and ‘v’, the volume of culture used in ml

white colonies were recovered and purified to give growth. If the mutation caused synthetic lethality then white colonies (that lack the shelter plasmid) would not be observed since plasmid loss would result in growth arrest. Therefore, lethality was inferred when either white colonies were not recoveredor were recovered but failed to purify further

To determine whether a particular mutation conferred lethality in the ppGpp0or ΔdksAbackground, an assay was devised based on the use of an unstable, easy to cure shelter plasmidpRC7, similar to that described previously(Bernhardt & de Boer, 2004). In the wild-type strain carrying pRC7, this plasmid can be lost at a frequency of 20-30% in the absence of the selection. However, this will not be seen if the plasmid loss leads to cell death. Since the plasmid pRC7 confers a lac+phenotype, in the absence of the selection plasmid loss can be visualized on X-gal IPTG containing plates as white colonies in a Δlac strain whereas the colonies that retain the plasmid will appear blue.In order to carry outsynthetic lethal screen in the ppGpp0or ΔdksAstrains, the spoT or dksAgenes cloned in pRC7 under the control of lacpromoter were used. Theseshelter plasmids,namely,pRCspoT or pRCdksA, respectivelywere transformed into the ppGpp0or ΔdksAstrain. To test the synthetic growth phenotypes, the mutations of the genes to be tested were introduced by phageP1 transductions. The resultingstrains were grown overnight in LBcontaining the antibiotic selection for the shelter plasmid and IPTG for expression of spoTor dksA, subsequently washedin minimal A medium and dilutions(usually 10−5or 10−6) of these cultureswere spreadon X-gal and IPTG containing plates without antibiotic selection for the shelter plasmid. The phenotypes of the white colonies in comparison with the blue colonies were noted. Viability of the strains was inferred when

or absence of a metabolite or a particular temperature. An EOP of ≤0.01 suggests lethality of the strain on the test medium. For strains carrying IPTG-dependent plasmids, EOP was determined by growing the strains overnight in medium containing IPTG and appropriate antibiotic,and spottingserial dilutions (100or 10–1to 10–6) on +IPTG (permissive) and –IPTG (test) plates to observe growth. Theviability is scored by takingratio of the colony forming units per ml (cfu/ml = No. of colonies × dilution factor × 1000/volume of culture spotted (in μl) obtained on the –IPTG plate to that on the +IPTG plate and determinesthe EOP. Likewise, strains carrying Ts plasmids were cultured overnight at 30°C with the appropriate antibioticand the serial dilutions of this culture were spottedat two temperatures 30°C (permissive) and 42°C (non-permissive or test). The ratio of cfu/mlobtained on the test temperature to that on the permissive temperature determined the efficiency of plating at the test temperature

Efficiency of plating (EOP) is a measure of the ratio of number of colonies (obtained from a given volume of a suitable culture dilution) on a test medium to those on a control or permissive medium, and is a measure of cell viability on the former. It is a very sensitive test and is often used for determining the viability of a strain in the presence

C. LBON temperature-sensitivityStrains were streaked on LBON agar plates and after an overnight incubation at42°C, growth was monitored (compared to that on LBON at 30°C as control). Absence of single colony growth was taken to reflect temperature sensitivity. D. In vivotranscription termination phenotypes The rationale for each phenotype is described in the relevant section. SMG-sensitivityThe E. coli relA mutants exhibit SMG-sensitive (SMGs) phenotype,that is,growth-inhibition in the presence of serine, methionine and glycine at 1mM concentration each(Uzan & Danchin, 1978)and is proposed to be a consequence of transcriptional polarity exerted by a frameshift mutation in the ilvG gene on the expression of downstream genes of the ilvGMEDA operon(Lopes & Lawther, 1989).This test was therefore used to distinguish relA+from relA−strains. Growth in the presence of amino acids serine, methionine, and glycine (SMG) was scored on glucose-minimal A plates supplemented with each of the amino acids at 40μg/ml and compared with the growth on non-supplemented glucose-minimal A plates to score for SMG phenotype. galEp3assayThis assay was used to test for relief of transcriptional polarity in the rho and nusG mutants. The galEp3 (galE490*) mutation represents a 1.3kb IS2 insertion in the gal leader region (between the promoter and structural genes of the galETKM operon). The mutation causes transcriptional polarity on the structural genes due to Rho-dependent transcription termination within IS2. In this assay, the gal operon expression in a galEp3 mutant or its derivatives was monitored by usingMacConkey galactose indicator plates (with 1% galactose), where Gal+colonies are red, and Gal−colonies are white. Therefore, the depth of color serves as an indicator of relative levels of gal expression, i.e., the extent of transcriptional polarity relief

A.lacZphenotype lacZ+colonies were distinguished from lacZ–colonies on X-gal containing plate or MacConkey lactose plate. X-gal is non-inducing colourless substrate of β-galactosidase enzyme which upon hydrolysis yields dark blue indolyl group and hence the lacZ+colonies on X-gal plate appear as dark blue colonies. Similarly, on the MacConkey agar plateslacZ+colonies appear dark pink whereas lacZ–colonies remain colourless. B. UV-sensitivityTo check the UV-sensitivity of the strains qualitatively, the strains were streaked on duplicate LB-agar plates and one of the plates was UV-irradiatedwith a 15-W UV-germicidal lamp at a distance of 70cm for 30 seconds. The UV-exposed and unexposed plates were incubated overnight in the dark after wrapping with aluminium foil and then growth was scored. This test could differentiate a recA–strain (UVs) from a recA+strain (UVr)

desired temperaturefor 45 minutes and plated on an appropriate selective medium at various dilutions. An aliquot of cell suspension to which plasmid DNA was not added served as a negative control. B. Inoue method i. Preparation of high efficiency competent cells Competent cells for high efficiency transformation were prepared by the method of (Inoueet al., 1990)with few modifications. An overnight culture of the strain (routinely DH5α) was subculturedinto fresh sterile LB broth in 1:100 dilutions and grown at 18ºC to anA600of 0.55. The cells were harvested by centrifugation at 2500rpm for 10 minutes at4ºC. Thesecells wereresuspended in0.4 volumes of INOUE buffer andincubated in ice for 10 minutes. The cells were recovered by centrifugation at 2500rpm at 4ºC for 10 minutes and finally resuspended in 0.01 volume of the same buffer. Sterile DMSO was added to a final concentration of 7%. After incubating for 10 minutes in ice, the cells were aliquoted in 100μl volumes, snap frozen in liquid nitrogen and stored at –80ºC. ii. Transformation protocolFor transformation, the required number of vials wasthawed on ice and the transformation protocol as described for CaCl2method was employed

A. Calcium chloride(CaCl2)method For routine plasmid transformation, following method which is a modification of that described by(Cohenet al.,1972)was used. An overnight culture of recipient strain was subcultured 1:100 in fresh LB medium and grown till mid-exponential phase. The culture was chilled on ice for 20 minutes, and the steps thereafter performed at 4ºC. 10 ml of culture was centrifuged and pelletwas resuspended in 5 ml of 0.1M CaCl2. After 5 minutes of incubation on ice, the cells were again centrifuged and resuspended in 1ml of 0.1M CaCl2. The suspension was incubated onice for 45 minutes. To the 100μl aliquot of the cellsuspension plasmid DNA (20-200ng in less than 10μl volumes) was added, incubated for 30-40 minutes on ice and given a heat shock for 90 seconds at 42ºC. The cultures were rapidly chilled for 1 minute, mixed with 0.9ml of LB broth and incubated at

Transformation

To 2 ml of fresh overnight culture of recipient strain, 108 pfu equivalent of phage lysate was added and incubated at 37ºC without shaking for 30 minutes to facilitate phage adsorption. The unadsorbed phage particles were removed by centrifugation at 6000 rpm for 5 minutes and the pellet ofbacterial cells was resuspended in 5 ml of LB broth containing 20 mM sodium citrate to prevent further phage adsorption. This was incubated for 25-60 minutes at desired temperaturewithout shaking to allow the phenotypic expression of the antibiotic resistance gene. The mixture was then centrifuged and the pellet was resuspended in 300 μl of 0.1M citrate buffer. 100 μl aliquots were spreadon appropriate antibiotic containing plates supplemented with 2.5 mM sodium citrate. A control tube without addition of P1 lysate was also processed in the same way. In the case of selection of nutritional requirement, the infection mixture was centrifuged, resuspended in 300 μl of 0.1M citrate buffer and plated without phenotypic expression

10–6)were mixed with 0.1 ml of fresh culture grown in Z-broth. After 30 min of adsorption at 37ºC without shaking, each mixture was added on a soft agar overlay of Z-agar plates and incubated overnight at 37ºC. The phage titrewas calculated from the number of plaques obtained on the plates as follows: Phage titre(pfu) per ml = No. of plaques ×dilution factor ×1000/vol.of lysate added (in μl)

Phage P1 transduction

0.3 ml of overnight culture of the donor strain in Z-broth was mixed with 107plaque forming units (pfu) of a stock P1 phage lysate prepared on strain MG1655. Adsorption was allowed to occur at 37ºC for 30 minutes and the lysate was prepared by broth method. To 0.3 ml of infection mixture, 8-10 ml of Z-broth was added and incubated at 37ºC with slow shakinguntil the visible lysis of the culture occurred (in 4-6 hours). The lysate was treated with 0.2ml of chloroform, centrifuged and the clear lysate wasstored at 4ºC with chloroform.Quantitation of Plaque forming units (pfu)To quantitate the titreof P1 lysate preparation, titration was done using P1 phage sensitive indicator strain such as MG1655. 100 μleach of dilution of phage (typically 10–5,

Adipose tissue is no longer considered to be an inert tissue that stores fat. This tissue is capable of expanding to accommodate increased lipids through hypertrophy of existing adipocytes and by initiating differentiation of pre-adipocytes. Adipose tissue metabolism exerts an impact on whole-body metabolism. As an endocrine organ, adipose tissue is responsible for the synthesis and secretion of several hormones. These are active in a range of processes, such as control of nutritional intake (leptin, angiotensin), control of sensitivity to insulin and inflammatory process mediators (tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), resistin, visfatin, adiponectin, among others) and pathways (plasminogen activator inhibitor 1 (PAI-1) and acylation stimulating protein (ASP) for example). This paper reviews some of the biochemical and metabolic aspects of adipose tissue and its relationship to inflammatory disease and insulin resistance.

It will be observed that the basis of confederation now proposed differs from that of-the-United States in several important particulars. It does not profess to be derived from the people, but would be the Constitution provided by the Imperial Parliament; thus affording the means of remedying any defect, which is now practically impossible under the American Constitution.

Import duty on air conditioners, refrigerators and washing machines under 10-kilogram capacity has been doubled to 20 percent each from 10 percent earlier. The basic customs duty on radial tyres is now 15 percent compared with 10 percent earlier,

It appears therefore that the only alternative which now offers itself to the inhabitants of Lower Canada is a choice between dissolution pure and simple, or Confederation on one side, and representation by population on the other. And however opposed Lower Canada may be to representation by population, is there not imminent danger that it may be finally imposed upon it, if it resist all measures of reform, the object of which is to leave to the local authorities of each section the control of its own interests and institutions. We should not forget that the same authority which imposed on us the Act of Union, or which altered it without our consent, by repealing the clause which required the concurrence of two thirds of the members of both Houses in order to change the representation respecting the two sections, may again intervene to impose upon us this new change.

In order to protect local interests, and to prevent sectional jealousies, it was found requisite that the three great divisions into which British North America is separated, should be represented in the Upper House on the principle of equality. There are three great sections, having different interests, in this proposed Confederation.

To the Upper House is to be confided the protection of sectional interests ; therefore is it that the three great divisions are there equally represented, for the purpose of defending such interests against the combinations of majorities in the Assembly.

But the very essence of our compact is that the union shall be federal and not legislative. Our Lower Canada friends have agreed to give us representation by population in the Lower House, on the express condition that they shall have equality in the Upper House. On no other condition could we have advanced a step ; and, for my part, I am quite willing they should have it. In maintaining the existing sectional boundaries and handing over the control of local matters to local bodies, we recognize, to a certain extent, a diversity of interests ; and it was quite natural that the protection for those interests, by equality in the Upper Chamber, should be demanded by the less numerous provinces.

the Lieutenant-Governor, who will enjoy the right of reserving the bills of the Local Parliament for the sanction of the Governor General, will be appointed by the Governor General in Council, that is to say, by the Federal Government, and, as a matter of course, it must be expected that he will act in conformity with the views of the Federal Government. Any bill reserved by him will require to be sanctioned by the Federal Government, which may refuse such sanction if they think proper, as they undoubtedly will as regards any bill the object of which might be to give responsible government to Lower Canada, whilst all the other provinces would only have governments which were not responsible. And the militia,—it will be exclusively under the control of the Federal Government. Have the honorable the French-Canadian members, to whom I more particularly address myself at this moment, reflected on the danger to us that is contained in this provision ?

My hon. friend from Wellington admits that under the Constitution we have the power to alter the constitution of this House in so far as it relates to Canada, but he says we are not authorized to extend our action to the other provinces, in a scheme of Federal union. That is begging the question. I answer his objection that any change affecting the elective principle is a breach of trust. Besides, we do not propose to enact a system of Government embracing all British North America We have not the power to do so. We merely propose to address Her Majesty on the subject. The Imperial Parliament alone has that power ; but if we have power without a breach of trust to alter the constitution of the Legislative Council of Canada (and my hon. friend admits this), then, certainly, we cannot be guilty of a breach of trust in suggesting a change embraced in a Constitution for the various provinces.

and dissent from others, of his opinions. The essential conditions of a valid trust to express particular opinions in Parliament are then wanting. The persons nominating him to his office, do not concur as to the opinions which he is to express. How then can a trust exist which it is impossible to define. The real trust imposed on the representative is co-extensive with those obligations, which alone the trust-makers can generally confer on him,—namely, to exercise his representative power honestly and discreetly. This argument, of course, assumes that the candidate has not defined his parliamentary obligations by unconditional pledges.

That the elective members had received a sacred trust to exercise ; that they were seut here by their constituencies to represent them, and to do that only. Under these circumstances, how could they conceive they had the power to vote away the rights of their electors? That was not their mandate, and if they did, they would be doing that which they had no authority to do ; they would be doing that which they could not do without going beyond the authority con faded to them. Now, it must be frankly admitted that if the hon. gentleman’s position’ be correct, then his objection would be fatal to any elected member giving his concurrence to the scheme of the Conference. But , hon. gentlemen, let us enquire what is the position of a representative. Two elements enter into the idea of representation— namely, power and duty. A representative derives the former from his constituents acting by their majority, under the Constitution. From what source does he derive the latter ? Obviously not from his constituents, because even the majority are not agreed on all points connected with the discharge of his duty. My hon. friend (Hon. Mr. SANBORN) has spoken of the position of a representative, as being that of a trustee. I shall quote from a very able work on the British Commonwealth, in which that position is, to my mind, very fully and very satisfactorily proved to be incorrect. Cox says :— Any trust, to be obligatory in conscience, must be defined by the self-same persons who appoint the trustee, or the person who is to fulfil the trust. His powers and duties must be derived from identically the same authority, for it obviously would be contrary to morals, as it is to law, that a man would be bound in conscience to exercise, in a particular way, powers delegated to him by several others, when trey themselves, while delegating those powers, differ as to the mode in which they are to be exercised. For, which of the different ways is the trustee to choose? By whom of those who appoint him is he to be guided in preference to the rest ? At the most he is bound to exercise his trust in a particular way in those particulars only respecting which the trust makers are agreed. Let us now apply this abstract principle of equity to the relations between a representative and his constituents. Regard him as their trustee. With respect to the source of his power there is no ambiguity ; it is derived from his constituents acting by their majority. But from whom does he derive the duty of expressing this or that opinion in Parliament ? In what particular are the trust-makers agreed? The very majority who voted for him are rarely, perhaps never, all agreed on any one point on which their opinions have been compared with his. Some of them differ from him on some points, some on others, but they all voted for him, from personal consideration, or because of their agreement with him on those points which they respectively deemed most important. In the minority, also, are probably some electors who assent to some,

HON. MR. CHRISTIE—A number of the representatives in the Federal Congress who voted for it were democrats, and without their concurrence and support it could not have been carried. Besides, that was only an amendment, not a revision of the Constitution. The Constitution of the United States was not the work of a party. The revision of the Constitution of the State of New York, in 1846, was not the work of a party I t is not desirable that any Constitution should be the work of a party ; in so important an undertaking all party spirit should be laid aside. (Hear, hear.) Why ? Because men of all parties are alike interested in the formation of a Constitution, and because in the construction of such an instrument , the collective wisdom of the leading men of all parties is needed. Besides, a Constitution so framed will be more likely, as my hon. friend from Wellington has so well said, to live in the hearts and affections of the people. (Hear, hear.) To show the good sense of our neighbors on this point, they do not give the revision of a Constitution—and the work of the Conference was a revision of our Constitution—to any party, but to men specially chosen for the purpose, irom all parties ; and I think the Governor General, and the Lieutenant-Governors of the Lower Provinces acted most wisely when they selected men of all shades of political opinion to compose this Conference and to prepare this Constitution, because all party views and feelings being laid aside, the whole object and motive of the members of the body was to devise a scheme which would best tend to promote the good of their common country. (Hear , hear.)

HON. MR. CHRISTIE—The hon. gentleman, I see, has not changed the ground which he took the other day, and which is precisely as I stated it. He thinks it would have been to the public advantage if this question had been taken up and discussed by a party. In this, in my judgment, he is entirely wrong; and I say he can find no instance of a constitution having been revised by a party.

The honorable gentleman very correctly stated the manner in which the Federal Constitution may be amended, but he is in error as to the mode in which state constitutions may be revised. One of the most important of the States revised its Constitution in 1846. I refer to the State of New York. The modus operandi on that occasion was as follows :—An act was passed in the State Legislature authorizing the electors at large to choose delegates to a convention, for the express purpose of revising the Constitution. The instrument passed by the convention was then submitted to the Legislature for approval ; but the Legislature had no power to alter it. It had either to be rejected or accepted as a whole. It was so accepted, none of the details being altered. My hon. friend will see that while the Conference was composed of leading representatives of the people in the various provinces, those conventions are composed of gentlemen elected by the people for that special purpose; and that the only difference between them is in the mode of selection. However, in both cases, all political parties are represented.

Whenever a majority of the House of Representatives shall deem it necessary to alter or amend this Constitution, they may propose such alterations and amendments, which proposed amendments shall be continued to the next General Assembly, and be published with the laws which may have been passed at the same session, and if two-thirds of each house, at the next ses-

sion of said Assembly, shall approve the amendments proposed, by yeas and nays, said amendments shall, by the Secretary, be transmitted to the town, clerk in each town in this State, whose duty it shall be to present the same to the inhabitants thereof, for their consideration, at a town meeting legally warned and held for that purpose ; and if it shall appear in a manner provided by law, that a majority of the electors present at such meetings shall have approved such amendments, the same shall be valid, to all intents and purposes, as a part of this Constitution. That is the way one of the oldest states guards the rights and liberties of its people. Then here is another extract from the Constitution of the State of Mississippi, one of the new states, showing how the people there are protected against hasty innovation :— Whenever two-thirds of the General Assembly shall deem it necessary to amend or change this Constitution, they shall recommend to the electors, at the next election for members of the General Assembly, to vote for or against a convention; and if it shall appear that a majority of the citizens of the state, voting for representatives, have voted for a convention, the General Assembly shall, at their next session, call a convention, to consist of as many members as there may be in the General Assembly, to be chosen by the qualified electors in the manner, and at the times and places of choosing members of the General Assembly ; which convention shall meet within three months after the said election, for the purpose of revising, amending, or changing the Constitution.

alluded the other day to the conservative feature of the Senate in the United States, in allowing the same representation to small states as to the larger states. But this does not at all affect the general arrangement, because the large majority are large states. But while my honorable friend approves of this portion, he should have expressed an opinion on the whole system. In the United States, no change of Constitution can be effected without the consent of two-thirds of both branches of the Legislature, and that must afterwards be sanctioned by three fourths of the state governments. This is a conservative feature also.

We have had the Constitution of 1841 altered more than once—twice at least—since the union. If we find that some parts of the machinery do not work—if, after the establishment of the Confederation, we find some little error has been made—-we will then, no doubt, have power and authority also to alter it.

The DIGINET-PS research project involves the development and implementation of a connected urban infrastructure test field along a stretch of Straße des 17. Juni between Ernst-Reuter Platz and the Brandenburg Gate, designed to advance and validate automated and autonomous driving and its broad range of individual areas under real-life traffic circumstances. The test infrastructure is intended to provide central, regional and supra-regional companies and R&D institutes with the opportunity to field test automated driving within an authentic urban setting. This will establish Germany’s first pilot project to build a digital test field for automated driving in highly complex traffic situations. DIGINET-PS will contribute to implementing Berlin’s smart city strategy in the area of mobility and will also support the state’s Digital Agenda.

The research project eMobility-Scout deals with the conceptualization, implementation and testing of a cloud-based IT solution for the operation of electric vehicles and for sharing charging infrastructures among different businesses. In doing so, eMobility-Scout is considering the interest shown by many companies and institutions for simple and smart integration of electric vehicles into their fleets. Solutions for diverse areas of application in commercial mobility are being developed and tested, while taking logistical, economic and ecological aspects into account. Experienced project partners and affiliates, as well as renowned end users, are contributing extensive knowledge to the project. The results of the research project for IKT EM III should also gain substantial recognition in the public sphere.

A fully integrated logistics concept to establish environment and climate friendly supply chains in urban districts is going to evolve from the project. Co-creation processes, which are supported by online tools, are being used to develop the concept. The development and testing of sustainable business and deployment models is the goal of Distribut(e) and this will be addressed through the development of a shared e-logistics system in Klausenerplatz and at Mierendorff-Insel. The system will relate to a specific district (Kiez) in Berlin. A digital dialogue platform will be set up for the purpose of ordering local goods and for the booking of cargo bikes.
