Reduced temperature

Workers in underground coal mines are always at risk of heat shock due to high temperatures and narrow spaces. To reduce the temperature in the longwall faces, some mines have used air conditioners to increase the cooling capacity, creating a better working environment for miners

This study comprehensively analyzes the impact of temperature and curing time on the compressive strength of geopolymer concrete made with locally sourced sea sand and seawater. The research aims to utilize abundant regional materials while reducing the environmental footprint associated with traditional construction practices.

In international pistol shooting competition the performance improvement needed to be able to move into a medal winning position in a final from fourth position is 1.5 points (Bedford et al., 2012). It may be expected therefore, that by providing a method of reducing tremor resulting in a corresponding performance improvement. This research consists of two studies investigating the physiological response and the shooting performance of elite pistol shooters.

This thesis has two key results, a study on the effect of carbon in electron-beam deposited platinum nano-wires and a novel temperature sensing glass substrate for marker-free thermometry. The thesis focus on the effect of carbon contamination in plasmonic nano-wires composed mainly of platinum produced from FEBID. Because carbon acts as an insulator in the platinum/carbon composite, we model the effect of carbon impurities by reducing the charge carrier concentration inthe platinumwire.

Industrial garden is a new approach, especially for competition in increasing pollution in the atmosphere. It helps easily to beautify the industrial areas. The lawn laid in vacant lands not only adds beauty but also cut down dust. These gardens are designed to reduce pollution and beautify the world. These units are the most sources of air, water, noise and soil pollution.

High-Level Recombinant Protein Production in CHO Cells Using Lentiviral Vectors and the Cumate Gene-Switch developed  an efficient system to generate in less than 2 months, starting from the cDNA, pools of CHO cells stably expressing high-level of recombinant  proteins. It is based on lentiviral vectors (LVs) for stable transduction coupled with the cumate gene-switch for inducible and efficient gene expression.

The role of coenzyme binding in regulating interflavin electron transfer in human cytochrome P450 reductase (CPR) has been studied using temperature-jump spectros-copy. Previous studies [Gutierrez, A., Paine, M., Wolf, C.R., Scrutton, N.S., & Roberts, G.C.K.Biochemistry (2002) 41,4626–4637] have shown that the observed rate, 1/s, of interflavin electron transfer (FADsq )FMNsq fi FADox)FMNhq) inCPRreduced at the two-electron level with NADPH is 55 ± 2 s )1 , whereas with dithionite-reduced enzyme the observed rate is 11 ± 0.

Temperature effects on the kinetic properties of phosphofructokinase (PFK) purified from skeletal muscle of the golden-mantled ground squirrel, Spermophilus lateralis, were examined at 37
C and 5
C, values character-istic of body temperatures in euthermia vs. hibernation. The enzyme showed reduced sensitivity to all activators at 5
C, theKa values for AMP, ADP, NH4 + and F2,6P2 were 3–11-fold higher at 5
C than at 37
C. Inhibition by citrate was not affected whereas phosphoenolpyruvate, ATP and urea became more potent inhibitors at low temperature. ...

We have investigated the conformational changes of New-castle disease virus (NDV) glycoproteins in response to receptor binding, using 1,1-bis(4-anilino)naphthalene-5,5-disulfonic acid (bis-ANS) as a hydrophobicity-sensitive probe. Temperature- and pH-dependent conformational changes were detected in the presence of free bovine gan-gliosides. The fluorescence of bis-ANS was maximal at pH 5.

VACUUM DISTILLATION TOWER In order to further distill the residuum from the atmospheric tower at higher temperatures, reduced pressure is required to prevent thermal cracking. The process takes place in one vacuum distillation tower. The principles of vacuum distillation resemble those of fractional distillation and, except that larger-diameter columns are used to maintain comparable vapor velocities at the reduced pressures, the equipment is also similar.
