Genetic Effect Of The Dwarfing Genes On Some Culm Characteristics Associatcd With Lodging Resistance In Bread Wheat, Md. Mahbub Hasan

Md. Mahbub Hasan

Due to the challenge of screening traits related to lodging resistance under natural field conditions, selection for lodging resistant varieties in wheat breeding programs is difficult. The identification of easily measurable culm anatomical traits related to lodging resistance would simplify the selection process. The present study was conducted to determine the effect of dwarfing genes on culm anatomical traits related to lodging resistance in our of basal internode 1. Field and laboratory study was conducted in Shahjalal University of Science and Technology, Sylhet, Bangladesh with eight wheat genotypes having Rhr1, Rht2 dwarfing genes in them and a local land race …

Effects Of Different Denture Cleansers On The Tensile Bond Strength Of Denture Liners, Selda Keskin

The effect of two denture cleansers (Polident1 and Protefix1) on the tensile bond strength between four soft liner materials (Molloplast B1, Permaflex1, Sofreliner Tough Medium1, and GC Reline Soft1) and a conventional denture base resin was investigated. For each of the liner materials 35 test specimens were prepared according to test the requirements and assigned into seven groups (n¼5). Before tensile testing, five of the liner specimens were kept in water or soaked in two cleansing solutions during 2 and 7 d. Five other samples served as a control group subjected directly to tensile testing. The bond strength values were …

E-Science @ Umass: Anticipating And Supporting E-Science Activities At The University Of Massachusetts, Maxine G. Schmidt, Rebecca Reznik-Zellen

Maxine G Schmidt

In March of 2008 an Ad Hoccommittee of Science Librarians from the University of Massachusetts Five Campus System convened to discuss the challenges of e-science and prepare the Libraries for their role in e-science initiatives. Three primary outcomes intended to support e-science activities emerged from the work of the Ad Hoc committee.

e-Science @ the University of Massachusetts Abstract: What is e-Science and how can libraries and librarians support it? The University of Massachusetts takes a proactive approach to support network-enabled research on its campuses and provides examples where e-Science is already at work. Statement: “e-Science” is a term commonly used to describe research in a networked environment, a growing trend not only in the sciences, but the arts and humanities as well. e-Science creates both opportunities and challenges for academic libraries. The opportunities lie in leveraging the basic skill set that libraries and librarians already possess: the knowledge of and practical …

High-Throughput Protein Purification For X-Ray Crystallography And Nmr, Rachele M. Hendricks-Sturrup

Rachele M Hendricks-Sturrup

In structural biology, the most critical issue is the availability of high-quality samples. “Structural-biology-grade” proteins must be generated in a quantity and quality suitable for structure determination using X-ray crystallography or nuclear magnetic resonance. The additional challenge for structural genomics is the need for high numbers of proteins at low cost where protein targets quite often have low sequence similarities, unknown properties and are poorly characterized. The purification procedures must reproducibly yield homogeneous proteins or their derivatives containing marker atom(s) in milligram quantities. The choice of protein purification and handling procedures plays a critical role in obtaining high-quality protein samples. …

The Sn-IV atom in the title compound, [Sn(CH3)(2)-(C18H11ClN2O3)], shows a trans-C2NO2Sn trigonal-bipyramidal coordination; the axial O-Sn-O angle is 155.22 (5)degrees. The tridentate N'-(5-chloro-2-oxidobenzylidene)-3-hydroxy2-naphthohydrazidate dianion is stabilized by an intramolecular O-H center dot center dot center dot N hydrogen bond.

Hapipah Mohd Ali

The Sn-IV atom in the title compound, [Sn(C6H5)(2)(C18H11ClN2O3)], is O,N,O'-chelated by the deprotonated Schiff base ligand and further bonded by two phenyl rings in a distorted cis-C2SnNO2 trigonal-bipyramidal geometry [C-Sn-C = 125.7 (2)degrees]. The two phenyl rings are oriented at a dihedral angle of 55.2 (3)degrees. Intramolecular O-H center dot center dot center dot N hydrogen bonding is present in the crystal structure.
