The thesis "Racist disinformation on the Web: the role of anti-racist sites in providing balance" provides a synthesis of the academic literature and media coverage related to Australian racism and racist disinformation on the Web, leading to new insights about the range and depth of issues concerned. An analysis of the data collected concludes that while anti-racist websites take on diverse roles in tackling racism, few provide content directly to balance Web racist disinformation.

In this work, the equipment was used to investigate the distribution of lithium (7Li) and boron (11B) in the outer oxide at the bow contact area. Depth profiling in the clad oxide at the opposite side of the rod to the point of contact, which is considered to have experienced normal operating conditions and which has a typical oxide thickness, evidenced levels of ∼10–20 ppm 7Li and a 11B content reaching hundreds of ppm in the outer parts of the oxide, largely in agreement with the expected range of Li and B clad oxide concentrations from previous studies.

Colloidal silver nanoparticles were synthesized by
Co-60 ray irradiation of Ag+ in aqueous solution containing polyvinyl alcohol (PVA) as stabilizer and 0.5 M ethyl alcohol as free radical (OH• ) scavenger. The effect of Ag+ concentration which varied from 1 to 50 mM on the saturated conversion dose (D) of Ag+ into Ag determined by UV-vis spectroscopy and the size of Ag nanoparticles characterized by transmission electron microscopy (TEM) were investigated. The dependence of D (kGy) and average size (d, nm) of Ag nanoparticles on Ag+ concentration was found out to be as: D (kGy) = 0.

A search has been initiated for lead inhibitors of the non-structural protein 3 (NS3)-associated NTPase/helicase activities of hepatitis C virus,the related West Nile virus, Japanese encephalitis virus and the human mitochondrial Suv3 enzyme. Random screening of a broad range of unre-lated low-molecular mass compounds,employing both RNA and DNA substrates, revealed that 4,5,6,7-tetra-bromobenzotriazole (TBBT) hitherto known as a potent highly selective inhibitor of protein kinase 2,is a good inhibitor of the helicase,but not NTPase,activity of hepa-titis C virus NTPase/helicase. ...

Cdc37 is a molecular chaperone that interacts with a range of clients and co-chaperones, forming various high molecular mass complexes. Cdc37 sequence homology among species is low. High homology between yeast and metazoan proteins is restricted to the extreme N-terminal region, which is known to bind clients that are predominantly protein kinases.

The cometabolism of citrate and glucose by growing Lactococcus lactisssp. lactis bv. diacetylactis was studied using a natural-abundance stable isotope technique. By a judicious choice of substrates differing slightly in their 13 C/ 12 C ratios, the simultaneous metabolism of citrate and glucose to a range of compounds was analysed. These end-products include lactate, acetate, formate, diacetyl and acetoin. All these products have pyruvate as a common intermediate.

Biomimetic recognition elements employed for the detection of analytes are commonly based on proteinaceous affibodies, immunoglobulins, single-chain and single-domain antibody fragments or aptamers. The alternative supra-molecular approach using a molecularly imprinted polymer now has proven utility in numerous applications ranging from liquid chromatogra-phy to bioassays.

ESI greatly enhanced the ability to characterize protein and peptides by MS.
ESI requires the sample of interest to be in solution- flow in to the ionization source region.
To ionize the sample, high voltage is applied, result in the sample becoming positively or negatively charged; however, positive ionization is used primarily in the analysis proteins and peptides.
As it exits the spray tip, the solution produces submicrometer-sized droplets containing both solute and analyte ions. The sample is then desorbed of solute prior to entering the analyzer region....

Dynein, which is a minus-end-directed microtubule motor, is crucial to a range of cellular processes. The mass of its motor domain is about 10 times that of kinesin, the other microtubule motor. Its large size and the diffi-culty of expressing and purifying mutants have hampered progress in dynein research.

Gas chromatography – chromatography using a gas as the mobile phase and a solid/liquid as a stationary phase – In GC, the analytes migrate in the gas phase, so their boiling point plays a role – GC is generally applicable to compounds with masses up to about 500 Da and with ~60 torr vapor pressure at room temp (polar functional groups are trouble) Supercritical fluid chromatography – chromatography using a supercritical fluid as the mobile phase and a solid/liquid as a stationary phase – In SFC, the analytes are solvated in the supercritical fluid – SFC is applicable to a much wider range ...

BMI (Body mass Index) là chỉ số được tính từ chiều cao và cân nặng, là một chỉ số đáng tin cậy về sự mập ốm của một người. BMI không đo lường trực tiếp mỡ của cơ thể nhưng các nghiên cứu đã chứng minh rằng BMI tương quan với đo mỡ trực tiếp, như đo trọng lượng dưới nước hoặc chụp x quang DXA – Dual energy x – ray absorptiometry. BMI là phương pháp không tốn kém và dễ thực hiện để tầm soát vấn đề sức khoẻ. 1. Sử dụng BMI như thế nào? BMI được sử...
