so let's suppose let's suppose your listeners are with me and you know we kind of agree like okay yes transformation's necessary and uh again i want to emphasize i'm not talking about reform i'm not talking 00:58:59 about a softer better capitalism i'm not talking about you know improved voter registration or like any of those things i'm talking about de novo starting over from scratch what might be 00:59:13 best and if it turns out that the old systems were better than anything that humanity can come up with well then you know that's the answer but i can't imagine that's true because the old systems were never designed in any kind of 00:59:25 you know thoughtful science driven [Music] you know process to to to test to explore and to come up with fitness like what is the you know we don't even have a fitness for our current society 00:59:39 much less of fitness for societal designs i mean we have the gdp but that's a terrible terrible limited fitness metric 00:59:51 okay so suppose you're with me suppose we're we're on board we we want to do this de novo design thing where do we start what's the what's what where do we even get off the 01:00:03 ground on this and i suggest that the way to do it is through first address worldview from world view once we understand what the world view is 01:00:15 what a reasonable useful world view will be for this project then then purpose derives worldview begets purpose once you understand what it is you want 01:00:28 what you value what do you value once you understand what you value then you can say well i value a and therefore the purpose is to 01:00:39 have a manifest in society for example so once you have purpose then you can think about what metrics how would you measure whether are you so 01:00:53 here's a new design is it fit for purpose does it do does it fulfill its purpose you know that's the question and then metrics go with some kind of fitness evaluation 01:01:05 and then finally last of all of those would be the design okay we know what we know what we value we know what this thing is supposed to do we know what the purpose is we know that attractor is supposed to you know plow the ground or something we 01:01:18 know what this is supposed to do we know how to measure success and uh now finally then let's talk about design what are the what are the you know the specifics and mechanics and 01:01:31 how does that happen and the the series is really kind of laid out this way the first paper really talks about world view and purpose the second paper talks about the you know the more the mechanics of things 01:01:44 like viability how would you make this thing viable things like that and then the very last paper that's titled the subtitle design okay so uh that's how we uh and 01:01:56 and maybe i will just mention here that i put metrics before design because we might have some ideas uh getting back to that preference factor we might have some ideas like we would like people not to die at 01:02:08 30 you know we'd like people to mostly live to a ripe old age and have you know enough water water to drink and food to eat and all that kind of stuff so uh you know what kind of design once 01:02:20 now that we have metrics to measure that kind of stuff longevity and nutrition and things what kind of designs would help us to reach those targets you know so that's one reason why design 01:02:31 why metrics comes before design okay

El factor tiempo de trabajo está también muy relacionado con la variabilidad de la presión de inyección, ya que a medida que incrementa el tiempo de operación de un motor, se incrementa el desgaste de las piezas, siendo agravado el sistema de alimentación por la variación de la calidad del combustible

When called upon, I delivered an effortless list of things I detest: blood sausage, intestinal pâté, brain pudding.I'd learned these words the hard way. Having given it some thought, I then declared my love for IBM typewriters,the French word for "bruise," and my electric oor waxer. It was a short list, but still I managed to mispronounceIBM and afford the wrong gender to both the oor waxer and the typewriter. Her reaction led me to believe thatthese mistakes were capital crimes in the country of France.

Plasmid isolation from miniprep method

An attempt was made to study the effect of storage of DNA extracts on DNA yield and purity. The DNA extracts were centrifuged and the supernatants were dispensed into 2.0 mL Eppendorf tubes and stored at -20 oC for a month. DNA precipitation and its quantification were carried out at a week intervals.

Effect of storage on soil/sediment DNA extracts

as well as commercial methods (MN kit, Germany; Mo-Bio kit, CA, USA; Zymo soil DNA kit, CA, USA) according to the manufacturer’s protocols and compared in terms of DNA yield and purity.

The soil DNA from Pantnagar and Lonar soil samples were also extracted by various manual (Desai and Madamwar, 2007; Agarwal et al., 2001; Yamamoto et al., 1998

solution was injected into the HPLC. A salt gradient of 0 to 0.2 M NaCl over a period of 120 minutes was run and fractions for each peak, as detected by measurement of UV absorbance at 220nm, were collected. An aliquot of each fraction was subjected to acetone precipitation and the obtained precipitate was analyzed on SDS-PAGE to ascertain which fraction corresponds to IgG. The IgG fractions from different runs were pooled and concentrated to -1 mg/ml which was then dialyzed against the digestion buffer (0.15 M NaCl, O.lM Tris-Cl, pH 7.1).

The collected ascitic fluid was centrifuged to remove cell debris and fat. Mouse monoclonal ascites, was filtered through glass wool to remove lipid like material left over after centrifugation. The supernatant was then subjected to (Nr4)zS04 fractionation. Saturated (Nlit)zS04 solution (SAS) at pH 7.0 was gradually added to the ascites in an ice bath with continuous stirring till a concentration of 40% (v/v) was achieved. The mixture thus, obtained was centrifuged to get the protein pellet and the pellet was re-suspended in buffer (0.01 M Tris-Cl, pH 8.5). The crude antibody solution obtained from ammonium sulfate fractionation was dialyzed against the wash buffer (0.0 1 \1 Tris-Cl, pH 8.5) and then subjected to ion-exchange chromatography using 5PW-DEAE (60x150 mm) column on a Waters3000 preparative HPLC (Waters, L:SA), to purify IgG. All solutions used during chromatography were filtered (0.451-lm) and then degassed. Following equilibration of the column with wash buffer, a 2 ml aliquot of the crude antibody

Antibody purification

650C in 0.2X SSC, 0.1 % SDS for I 0 min. The membrane was wrapped in Saran wrap and exposed to an X-ray film. The colonies that were positive by colony hybridization were inoculated in a 3 ml culture and used for preparing DNA for analysis by restriction digestion and Southern blotting. The digested DNA was resolved on a 0.8% agarose gel as described above. The gel was soaked in 4 volumes of denaturing solution (1.5 M NaCI and 0.5 M NaOH) for 1 h at RT with shaking followed by neutralization (1 M Tris HCI, pH 8 and 1.5 M NaCI) for 1 hat RT. The DNA was transferred to a Nylon membrane, UV crosslinked and hybridized with the full length 32p labeled· bZP3 probe as described above.

The ligation mixture was used for transformation of DH5a cells as described earlier. Transformed bacterial colonies growing on LB Amp plates were screened by colony hybridization. Briefly, colonies were grown for 6-8 h on a Nylon membrane placed on a LB Amp plate. The colonies were lysed by placing the membrane on a Whatman® 3MM paper soaked in I 0% SDS for 3 min, followed by treatment with denaturing solution (0.5 N NaOH, I.5 M Nael) for 5 min and neutralization solution (0.5 M Tris Hel pH 8, 1.5 . M Nael) for 5 min in the same manner. The membrane was dried, UV cross linked (Ultraviolet crosslinker, Amersham) and processed for prehybridization and hybridization. Stocks of 20X sse (174 giL NaCI, 88.2 giL sodium citrate, pH 7.0) and 50X Denhardt's (I% ficoll, I% PVP, I% BSA) were prepared. The membrane was prehybridized for 4-6 h in the prehybridization solution (5X SSe, 5X Denhardt's, 0.5% SDS, I 0 J..Lg/ml sheared and denatured salmon sperm DNA). The bZP3 DNA was labelled using the Multiprime DNA labeling system using 50 ng of purified bZP3 DNA. For hybridization with the probe, I o6 cpm/ml of the denatured 32p labeled bZP3 probe was added to the prehybridization solution and incubation was further carried out for I4-I6 h. For removing the non specifically bound probe, the membrane was washed successively at RT in 2X sse for 10 min, at 55°e in 0.2X sse, 0.1% SDS for 10 min and finally at

Screening of the Recombinant Transfer Vector

The cell pellet obtained from l ml culture was solubilized by boiling for 5 min in 100 J..Ll of 2X sample buffer (0.0625 M Tris, pH 6.8, 2% SDS, 10% glycerol, 5% BME and 0.001% bromophenol blue) and the proteins were resolved on a 0.1% SDS-10% PAGE (Laemmeli, 1970). The gel was stained with Coomassie brilliant blue for staining total cellular proteins. For immunoblotting, the proteins were electrophoretically transferred to 0.45 J..Lm nitrocellulose membrane overnight at a constant voltage of 15 V in Tris glycine buffer with 20% methanol (Towbin et al., 1979). Nonspecific sites on the membrane were blocked by incubation with 5% BSA in 50 mM phosphate buffered saline (PBS), pH 7 .4, for 1 h followed by 3 washes (15 min each) with PBS containing 0.1% Tween-20 (PBST). For detection of bZP3, a murine monoclonal antibody (MAb), MA-451, generated against the pZP3P and recognizing a cross reactive epitope (166-171 aa residues) within the bonnet sequence was used (Afzalpurkar and Gupta, 1997). The membrane was incubated for 1 h with a 1 :5 dilution of MA-451 culture supernatant, followed by 3 washes in PBST. Horseradish-peroxidase (HRPO) conjugated goat anti-mouse immunoglobulin (lg) was used to reveal bound Ab. Colour was developed with 0.6% (w/v) 4-chloronaphthol in 50 mM PBS, pH 7.4, containing 25% methanol and 0.06% H202. The reaction was stopped by washing the membrane with PBS.

SDS-PAGE and Immunoblot

Digestions involving more than one restriction endonuclease were carried out with 2 - 4 ug DNA in a final reaction volume of up to 50 or 100 ul. In these cases, if the two enzymes had radically different optimal assay conditions, the DNA was digested first with the enzyme requiring a lower salt concentration. After incubating for one hour, a 5 ul aliquot from the digestion reaction was electrophoresed on a mini gel to monitor the extent of digestion. Once the digestion was complete, appropriate amount of salt and the

second enzyme were added and the incubation continued in an increased final reaction volume, to offset any increase in the glycerol concentration in the new reaction. Alternatively, the DNA was extracted once with phenol/chloroform, once with chloroform, and then precipitated with one half volume of 7.5 M ammonium acetate and two volumes of ethanol. The precipitation was done for 30 minutes at room temperature, and the DNA spun down for 30 minutes at room temperature. The supernate was discarded, pellet washed with 70% ethanol, recentrifuged, dried briefly under vacuum and finally resuspended in 18 ul distilled water. The DNA purified in this manner could then be used for setting up digestion with a second enzyme or for setting up a ligation. For those double digestions where one of the enzymes was known to be active over a broad range of ionic strength conditions, including those required for the optimal activity of the second enzyme, both the enzymes were added simultaneously in the digestion reaction, which was carried out using the optimal conditions of the second enzyme having more stringent assay requirements.

Cultured promastigotes were harvested by centrifugation of suspension culture (500 ml) in falcon tubes at 3000 g for 10 min at 20°C in a cooling centrifuge (Rota 4R; Plastocraft). The clear spun media was carefully decanted and the pellet was resuspended in ice-cold phosphate buffered saline (PBS, 20mM, pH = 7.2). Centrifugation was done again as earlier and washings were collected in a separate falcon. The washing step with PBS was repeated twice. The promastigotes in PBS were then counted using a Neubauer chamber. For this an aliquot was taken and diluted with PBS (normally 10 J..ll original suspension was mixed with 60 J..ll PBS) and then formaldehyde was added to this (30 J..ll to give a final dilution of 1:10). After 10 minutes of fixing in formaldehyde, 10 J..ll of this diluted suspension was put under the coverslip on Neubauer chamber and counted. Total cell count was determined using the standard formula. For breaking cells to get membrane preparation,93 the cell pellet (6.5 x 109 cells) was suspended in 5 ml of hypotonic buffer (0.1 mM TlCK and 1 J..lg/ml leupeptin) and sonicated in ice (6 x 10 s pulses with 3 s intervals). Breaking of cells were assessed by a light microscope. The membrane protein was further processed as per the requirement of the experiment.

These cartridges were used to deliver DNA into epidermis of male/female mice. a) Preparation of DNA-gold microcarrier suspension Twenty five mg of gold microcarriers were weighed in a 1.5 ml eppendorf tube to which 100 J..Ll of 0.05 M spermidine was added and vortexed for 10 sec. To the above mixture 100 J..Ll of DNA (0.5 mg/ml) was added and vortexed for another 10 sec. While vortexing, 100 J..Ll of 1 M CaCh was added dropwise to the mixture and left at RT for 10 min to allow precipitation of DNA onto gold microcarriers. The DNA-gold pellet was collected by centrifuging at 12,000 X g for 1 min at RT. The pellet was washed thrice with 100% ethanol (freshly opened bottle), resuspended in 3 ml of 0.1mg/ml polyvinylpyrollidone (PVP) in ethanol and stored at -20°C till further use. b) Loading the DNA/microcarrier suspension into gold-coat tubing using the tubing prep station A 25 inch length of tubing was cut and fixed on tubing prep station, air dried by passing nitrogen gas through it for 15 min. The DNA/microcarrier suspension was vortexed and injected into the tubing using a 5 ml syringe and the microcarriers allowed to settle in the tubing for 3 min. Ethanol from the tubing was removed by slowly sucking into the syringe. The tubing was rotated, while passing the nitrogen gas, using the tubing prep station, for 20-30 sec to allow the microcarriers to evenly coat the inside of the tubing. c) Preparation of cartridges using the tubing cutter The tubing was cut into 0.5 inch long pieces (cartridges) by using the tubing cutter and cartridges stored at 4°C in vials containing desiccant pellets till further use.

Cell wall β-glucan measurement was carried out as describedpreviously with some modifications(Kapteynet.al.,2001). Briefly, cell wall fractions were washed multiple times with 1 N NaCl. Washed cell walls were boiled twice in 50 mM Tris-HCl(pH 7.8) containing 2% SDS, 100 mM Na-EDTA and 40 mM β-mercaptoethanol for 5 min to remove non-covalently linked proteins and other contaminants. SDS-treated cell wall fraction was collected and rinsed thrice with water. For β-glucan isolation, cell wallswere extracted three times, each for 1 h, in 0.5 ml 3% NaOH at 75 ̊C and centrifuged at 1,200 g.All 3% NaOH supernatant fractions were saved for isolation of mannan as described below. 3% NaOH-extractable cell wall pelletwasneutralized twice in 100 mM Tris-HCl (pH 7.5) and once in 10 mM Tris-HCl (pH 7.5) and digested with 5 mg/ml zymolyase-20T in 10 mM Tris-HCl (pH 7.5) for 14-16 h at 37 ̊C. This treatment liberates approximately 90-95% glucose into the supernatant. Total glucan content in the cell wall was measured by estimating glucose from both the solubilised supernatant and zymolyase-20T insoluble pellet fractions with phenol-sulphuric acid carbohydrate estimation method using purified glucose as the standard
