    1. For many amorphous and crystalline semiconductors,an exponential dependence of absorption coefficientα<104cm−1may take Urbach’s empirical formula [28]:av=a0exphv/EU,wherea0is a constant andEU(Urbachenergy) is an energy characterizing the degree of disorderintroduced from defects and grain boundaries; also, it is inter-preted as the width of the tail of localized states associated withthe amorphous states in forbidden band. Figure 12 representsthe logarithm of absorption coefficient as function of thephoton energy at different deposition times 20, 30, 40, and50 min. The value ofEUis calculated from the inverse slopeof the linear part of curves and also listed in Table 3

    1. “You are free to eat from any tree in the garden;(W) 17 but you must not eat from the tree of the knowledge of good and evil,(X) for when you eat from it you will certainly die.”

      God instructed Adam and Eve to eat whatever they desired, though prohibited them to eat from the tree of the knowledge of good and evil. In Robin Wall Kimmerer's "Skywoman Falling", she explained how in Indigenous culture, they follow Original Instructions. These "instructions" are not rules but rather guidelines for each person. Kimmerer explains how during Skywoman's time, the first people's understanding of the Original Instructions were to care for the and have respect for hunted animals, value family, and hold respectful ceremonies for their beliefs.

The standard curve was plotted and the equation derived, used to calculate the number of metabolically viable cells in experimental groups. Percentage of viable cells was calculated by comparing the number of viable cells in treated wells with that of untreated wells
    2. MTT micromethod is a colorimetric assay based upon the conversion of the (yellow) MTT reagent (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide), a tetrazole to purple formazan in the mitochondria (succinate dehydrogenase) of the living cell which is quantified by measuring the optical density at 570nm. When the amount of purple formazan produced by untreated control cells is compared to that of treated cells, the effectiveness of the agent can be deduced through the production of a dose-response curve. Parasites in their log phase were harvested and the dead cells removed at 129 x g for 5min at RT. The live cells were resuspended in phenol red-free DMEM containing 10% FBS to a cell count of 2.5 X 107. 1mL of above culture was plated into each well of a 24 well plate and appropriate treatments were given for desired duration of time. Some untreated cells were also kept aside for generating the standard curve. After appropriate treatment, from each well of the 24 well plate 200pL was aliquotted into 4 wells of a 96 well plate. To each well of the 96 well plate, 10pL of MTT solution (5mg/ mL prepared in PBS and filtered with 0.22p filter) was added and the plate incubated at 23°C for 2-3 hours till colour develops in the control cells. A standard curve was also plated by taking different dilutions of untreated cells and processed similarly. Once colour developed, the reaction was stopped by lysing the cells using

    1. Cells (HEK293T) were transfected with various combinations of plasmids/siRNAsor treated with cisplatin. Cells were washed first with 1X PBSand then with Met-/Cys-1X DMEM supplemented with dialyzed FBS(10%). Cells were then incubated with Met-/Cys-DMEM supplemented with dialyzed FBS in the incubatorfor 1h (met/cysstarvation). Cells were taken out from the incubator,and the culture media was removed. Cells were placed behind the radioactivity protective shield and DMEM supplemented with 35S met/cys (200μCi) was added to the cells. Plates containing radioactive media were then put into the acrylic box and incubated for 1h at 37°C in a CO2 incubator. Plates were taken out and kept behind the radioactivity protective shield;the radioactive media was disposedofin the radioactive liquid waste. One set of cells washarvested for 0 time point, other sets of cells were washed twice with 1X PBS and were incubated with normal medium containing 2mM each of cysteine and methionine. Cell plates were put in the acrylic box and incubated at 37°C in a CO2 incubator. Cells were harvested at different time points. Cells were collected in ice-cold PBS and were lysed using the standard cell lysis protocol. Cell lysate were subjected to immunoprecipitation(IP). IP complex is separated on SDS-gel using standard protocol. The gel was transferred onto PVDF membrane, and the membrane was dried. Dried membrane was exposed in a cassette and the signal was detected using phosphorimager. Later the same blots were probed with specific antibodies

    1. Ferric-iron-reduction activity of Xanthomonas oryzaepv. oryzicolawas measured using ferrozine, a chromogenic ferrous iron chelator, as described previously (Velayudhan etal., 2000; Worst et al., 1998). For estimating the ferric reductase activity, Xanthomonas oryzaepv. oryzicolastrains were grown in 20 ml PS medium carrying appropriate antibiotics for 24 h to OD600 of 1. Cell free PS media was incubated under similarcondition to be used as control. Chromogenic ferrous iron chelator, ferrozine was added to a final concentration of 1 mM, and FeCl3was added as ferric iron source to a final concentration of 50 μM, and incubated at 28ºC. At regular time intervals, 1 ml aliquotes were taken from the test culture and control, centrifuged to remove the cells, and absorbance of the magenta coloured Fe2+-ferrozine complex in the cell free culture supernantant was measured at 535 nm by using control supernatant as reference. The Fe2+reduction activity was quantified as micromoles of Fe2+-Ferrozine complex formed

After confirming pRR14 and pRR15 constructs by sequencing, the constructs were then introduced into BXOR1 strain through biparental mating using E. coliS17-1. X. oryzaepv. oryzicolaGUS and GFP reporter strains were selected on PS medium plates containing suitable antibiotics. Since pVO155 cannot replicate in X. oryzaepv. oryzae, ampicillin and kanamycin-resistant colonies were obtained upon chromosomal integration of the plasmid using the cloned DNA sequence as a region of homology. pProbeGTcan replicate independently in Xanthomonasand report for the gene expression
    4. Glucuronidase (GUS) reporter gene fusion and GFP reporter fusion was created by using the suicide plasmid pVO155 having a promoterless gusAgene (Oke and Long, 1999), and pProbeGThaving a promoterless GFP (Miller et al., 2000). To construct the xsuA::gusAand xsuA::gfptranscriptional fusion, a 611-bp DNA fragment containing the putative promoter of the xssoperon (+213 to −398) was amplified by using the SCRsid_ pProbeGFP_F and SCRsid_ pProbeGFP_R primers (Table 2.2). This promoter fragment was subsequently digested with HindIII and BamHI,and directionally cloned upstream of the promoterless gusAand gfpgene in pVO155 and pProbeGTplasmids to create the xsuA::gusAand xsuA::pProbeGT(gfp) reporter constructs pRR1

    1. To perform immunoblotting or western blotting, appropriate amounts of total protein(ranging from 20-40 μg) were separated ona SDS-PAGE gel of 12%acrylamide concentration in Tris-Glycine-SDS gel running buffer. Protein separation was done at 70-100 V for 2-3 h using a MINI PROTEAN®3 electrophoresis unit (Bio-Rad). Followingseparation, proteins weretransferredto polyvinylidene difluoride (PVDF) membrane, using a Bio-Rad Mini Trans-Blot electrophoretic transfer unit in Tris-Glycine transfer buffer at 4⁰C. Before setting transfer assembly, PVDF membrane was first activated in 100% methanolfollowedby washesin the transfer buffer. The transfer assembly was set inaBio-Rad Mini gel holder cassette (170-3931)according to manufacturer’s instructions. The transfer time and current settings varied depending on the size oftheprotein of interest. Post transfer, membranes wereseparated from the assembly and kept for blocking intheblocking buffer (0.1 % Tween-20, 5% w/v fat-free skimmed milk in 1X TBS) for 1 h at room temperature with shaking. Next,membranes wereincubated with appropriate dilutions of primary antibodiesin the blocking buffereitherfor 3-4 h at room temperature or overnight at 4°C with gentle shaking. Post incubation,membranes were washed thrice with 1X TBS-T, 10 min each,with constant agitation. After washes, membraneswere incubated with appropriate dilutions of secondary antibodiesconjugated with horseradish peroxidase (HRP) for 1 h at room temperature with gentle shaking. Next, membranes were washed thrice with 1X TBS-T, 10 min each,with constant agitation. To visualize proteins, membranes were removed from TBS-T, and theHRP substrate ECL plus (Amersham Biosciences, RPN2232) was uniformly added on top of the membrane. Chemiluminescent signalswere captured in the western blot imaging system (FluorChemTME system)
    2. For protein extraction, cells were spun down at 4,000 rpm for 5 min and washed with ice-cold water. The cell pellet was resuspended in 250-500 μl of homogenisation buffer which contained50 mM Tris (pH 7.5), 2 mM EDTA, 1 mM phenylmethylsulphonyl fluoride (PMSF) (serine protease inhibitor), 10 mM sodium fluoride (serine/threonine and acid phosphatases inhibitor), 1 mM sodium orthovanadate (Tyrosine and alakaline phosphatases inhibitor) and 1X protease inhibitor cocktail (Sigma, P 8215). The cell suspensison was transferred to a 1.5 ml centrifuge tube and equal amounts of glass beads (0.5 mm size) were added. Cells were lysed mechanically by bead-beatinghomogenizer (MP Biomedicals, FastPrep®-24) atthemaximum speed for 60 seconds, five times each,with intermittent cooling on ice.After lysis, tubes were punctured at the bottom with the helpofasurgical needle, and the lysed cell suspension was collected in a fresh microcentrifuge tubes by putting the punctured tubes on top of the fresh tubes and centrifuging them at 3,000 rpm for 10 min. The supernatant was transferred toafresh microcentrifugetubeandprotein concentrationwasestimated usingtheBCA protein assay kit (Thermo scientific). Protein preparations werestored at -20°C until use

    1. Evaluation, when it is not asked for, and when it has consequences as it does in school, is a threat. It narrows the mind... it inhibits new learning, new insights, and creative thought—the very processes that some people think school is supposed to promote. -- Peter Gray

      Why is it clear to us that it's degrading and objectifying to measure and rank a girl’s physical body on a numeric scale, but we think it’s perfectly okay to measure and rank her mind that way?

      . . .

      what an oak tree actually needs is not your opinion but soil and water and light and air, and what a child needs is love and stories and tools and conversation and support and guidance and access to nature and culture and the world. If a kid asks for your feedback, by all means you can give it; it would be impolite not to. But what we should be measuring and comparing is not our children but the quality of the learning environments we provide for them.

    1. bishop gave judgment, declaring the marriage null in a canonical sense. Regarded in a civil point of view, the marriage was still valid until it should have been declared null by a civil tribunal. It became necessary, therefore, to carry the cause before the Superior Court, and my honorable friend, the member for Because, who took the case in hand with his usual zeal and legal address, obtained from the court, after a suitable inquiry, a judgment declaring the marred null in a civil sense, and ordering that it should be registered as such in all places where it should be needful. If this affair had occurred in Upper Canada, what recourse would the parties have had ? The parties being Catholics, the case would have been brought before the bishop, who would also have declared the marriage null after suitable inquiry; but the cause would not have had the same conclusion in the civil court, particularly had it depended on certain impediments which have force in Lower Canada, but none in Upper Canada. It would have become necessary to go to Parliament to pray for an act, which, in a Catholic point of view, would be a mere decree of separation, but which the Parliament would have termed an act of divorce. This power to grant a separation is therefore necessarily vested in the Parliament, by whatever names such separation may be designated, and we are not to be reproached for the interpretation which others may give to such name, different from that which we assign to it. I thought it right to make myself understood on this point, because I do not choose that people should be able to say we are afraid of explaining our position with regard to the question of divorce and marriage, and I believe that I have shown that our position is consistent with our religious laws and our principles as Catholics. I regret that I have dwelt so long on the matters touched upon by the honorable member for Hochelaga ; but after his speech, and considering the position he assumed, he must have expected an answer.

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    2. HON. SOL. GEN. LANGEVIN—I beg your pardon, it means that a marriage contracted in no matter what part of the Confederacy, will be valid in Lower Canada, if contracted according to the laws of the country in which it takes place ; but also, when a marriage is contracted in any province contrary to its laws, although in conformity with the laws of another province, it will not be considered valid. Let us now examine the question of divorce. We do not intend either to establish or to recognize a new right ; we do not mean to admit a thing to which we have constantly refused to assent, but at the Conference the question arose, which legislature should exercise the different powers which already exist in the constitutions of the different provinces. Now, among these powers which have been already and frequently exercised de facto, is this of divorce. As a member of the Conference, without admitting or creating any new right in this behalf, and while declaring, as I now do, that as Catholics we acknowledge BO power of divorce, I found that we were to decide in what legislative body the authority should be lodged which we found in our Constitutions. After mature consideration, we resolved to leave it in the Central Legislature, thinking thereby to increase the difficulties of a procedure which is at present so easy. We thought then, as we still think, that in this we took the most prudent course. The following illustration will prove this still more forcibly. I t is known to the House how zealous a partisan the honorable member for Brome (Mr. DUNKIN) is of the cause of temperance. Well, we will suppose that the honorable gentleman were present as a member of a municipal council in which it was to be decided whether all the taverns in a very populous part of the parish, which could not be suppressed, should be banished to a remote corner of the parish, where they would no longer be a temptation and a stumbling-block ; would he not vote for such a measure ? Would he not send them to a place where they would be least accessible to the population, and would he not think he had done a meritorious act, an act worthy of a good friend of the temperance cause ? Just so in a question of divorce ; the case is exactly analogous. We found this power existing in the constitutions of the different provinces, and not being able to get rid of it, we wished to banish it as far from us as possible. One thing it would be vain to deny, namely, that although we, as Catholics, do not admit the liberty of divorce, although we hold the marriage bond to be indissoluble, yet there are cases in which we both admit and require the annulling of the marriage tie—in cases, for instance, where a marriage has been contracted within the prohibited degrees without the necessary dispensations. An instance of this occurred very recently. A few months since, an individual belonging to my county, who had married a young girl of a neighboring parish, without being aware at the time of his marriage of the relationship which existed between him and his wife, found out several months afterwards that they were related in such a degree that they required a dispensation from the bishop. That dispensation had not been obtained. He spoke of it to his wife, who refused to apply for a dispensation, as a step towards the legal celebration of their marriage. It became necessary, therefore, to have the marriage annulled. The affair was brought before the Ecclesiastical Court, and, after a minute investigation, the diocesan

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    3. HON. SOL. GEN. LANGEVIN—The honorable member for Verchères does not choose to be convinced ; so I will make no further attempt to convince him. The resolution in question signifies just what I have stated.

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    4. may be summed up as follows :—The Central Parliament may decide that any marriage contracted in Upper Canada, or in any other of the Confederated Provinces, in accordance with the laws of the country in which it was contracted, although that law might be different from ours, should be deemed valid in Lower Canada in case the parties should come to reside there, and vice versa.

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    5. The honorable gentleman has asked the Government what meaning was to be attached to the word ” marriage,” where it occurred in the Constitution. He desired to know whether the Government proposed to leave to the Central Government the right of deciding at what age, for example, marriage might be contracted. I will now answer the honorable gentleman as categorically as possible, for I am anxious to be understood, not only in this House, but also by all those who may hereafter read the report of our proceedings. And first of all I will prove that civil rights form part of those which, by article 43 (paragraph 15) of the resolutions, are guaranteed to Lower Canada. This paragraph reads as follows :— 15. Property and civil rights, excepting those portions thereof assigned to the General Parliament. Well, amongst these rights are all the civil laws of Lower Canada, and among these latter those which relate to marriage; now it was of the highest importance that it should be so under the proposed system, and therefore the members from Lower Canada at the Conference took great care to obtain the reservation to the Local Government of this important right, and in consent-‘ ing to allow the word ” marriage ” after the word “divorce,” the delegates have not proposed to take away with one hand from the Local Legislature what they had reserved to it by the other. So that the word ” marriage,” placed where it is among the powers of the Central Parliament, has not the extended signification which was sought to be given to it by the honorable member. With the view of being more explicit, I now propose to read how the word marriage is proposed to be understood :— The word marriage has been placed in the draft of the proposed Constitution to invest the Federal Parliament with the right of declaring what marriages shall be held and deemed to be valid throughout the whole extent of the Confederacy, without, however, interfering in any particular with the doctrines or rites of the religious creeds to which the contracting parties may belong. This is a point of great importance, and the French Canadian members ought to rejoice to see that their fellow-countrymen in the Government have not failed in their duty on a question of so serious a nature. On many other points many of them will doubtless claim that we have not thoroughly fufilled our duty, but as regards the matter in question there can be no difference of opinion, as I we have all a common rule to guide us ; and I repeat that they ought to rejoice that their co-religionists in the Conference have not been found wanting on this occasion. The whole

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    1. Remarks have also been made about the laws of divorce and marriage, and the honorable member for the division of DeLanaudière (Hon. Mr. OLIVIER) told us that the Conference had done well in transferring the power of divorce to the General Government. On his part, I think this was a wise view of the question, and I am glad to have the opportunity of now telling him so. He was, however, very uneasy about the word ” marriage.” Well, I will try to put him right and at his ease on that point; and I will give him the answer as I find it put down in writing, so that no possible misunderstanding may continue to exist. If the honorable gentleman will but take his pen, he will be able to note my answer :—” The word ‘ marriage’ has been inserted to give the General Legislature the right to decide what form of marriage will be legal in all parts of the Confederation, without in any way interfering with the rules and prescriptions of the Church to which the contracting parties belong.”

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    2. One of them is a matter in which Lower Canada is somewhat peculiarly interested— the system of marriage and divorce, which, I see, is to be left in the hands of the Federal Government.

      §§.91(26) and 92(12) of the Constitution Act, 1867.

    1. what is meant by the regulation of the law of divorce ; but what is meant by the regulation of the marriage question ? Is the General Government to be at liberty to set aside all that we have been in the habit of doing in Lower Canada in this respect ? Will the General Government have the power to determine the degree of relationship and the age beyond which parties may marry, as well as the consent which will be required to make a marriage valid ?
