It is well known that the direct-space asymmetric unit definitions found in the International Tables for Crystallography, Volume A, are inexact at the borders. Face- and edge-specific sub-conditions have to be added to remove parts redundant under symmetry. This paper introduces a concise geometric notation for asymmetric unit conditions. The notation is the foundation for a reference table of ...

Diabatic potential energy surfaces are a convenient starting point for dynamics calculations of photochemical processes, and they can be calculated by the fourfold way direct diabatization scheme. Here we present an improved definition of the reference orbital for applying the fourfold way direct diabatization scheme to ammonia. The improved reference orbital is a geometry-dependent hybrid orbi...

Thomas Jefferson National Accelerator Facility Newport News, VA Abstract. The technologies of direct digital down converters, digital frequency synthesis, and digital signal processing are being used in many commercial applications. Because of this commercialization, the component costs are being reduced to the point where they are economically viable for large scale accelerator applications. T...

the dried fruit of terminalia chebula is widely used for its laxative properties. the objective of the present study was to examine the flowability and compressibility of terminalia chebula fruit powder, subsequently developing its tablet formulations by utilizing wet granulation and direct compression technology. initial studies on flowability and compressibility revealed that the fruit powder...

I consider how the saving behavior of consumers is affected by incomes in their reference group. Although standard life cycle models with interdependent preferences provide no clear cut prediction of how incomes in one’s reference group should influence savings, the empirical analysis points to an unambiguously negative effect: If incomes in the reference group are higher, savings are lower. Th...

background : the excessive changes in serum of lipids, lipoproteins and apolipproteins can be considered as strong risk factors for cardiovascular diseases.in particularlipoproteins can determine the risk of cardiovascular illnesses in teenyears (before showing clinical symptoms).studies have shown that the serum level of ldl c -hdl c is a function of the productionamount of apoa 1 and apob 100...

Objectives: The objective of this study is to test the hypothesis that the immature human brain exhibits slow electrical activity that is not detected by conventional (i.e. high-pass filtered) electroencephalography (EEG). Methods: Six healthy preterm infants (conceptional age 33–37 weeks) were recorded bedside with direct current (DC) EEG during sleep. Epochs with quiet sleep were selected to ...

Several methods exist for genotyping class II DLA gene polymorphisms in the dog. The most accurate method is sequence-based typing, which involves direct sequencing of polymerase chain reaction products. However, this method is expensive and unsuitable for large-scale studies. Recently, reference strand-mediated conformation analysis (RSCA) has been shown to be effective for characterizing majo...

Veterinary pharmacovigilance studies the adverse effects of veterinary medicinal products after they have been placed on the market. Information about suspected lack of efficacy, potential environmental risks as well as the validity of the drug withdrawal times are also taken into account. In France, information provided to the national veterinary pharmacovigilance system, which was formally es...

In this study of advertisements appearing in medical periodicals and by direct mail advertising to general practitioners, Dr. Stimson, a sociologist, concludes that from what is intended to provide therapeutic information hardly any therapeutic information is provided. He reminds the reader of the safeguards which surround all drug advertising by law and by the code of practice of the Associati...
