gam mutants of phage lambda carrying long palindromes fail to form plaques on wild-type Escherichia coli but do grow on strains that are mutant in the sbcC gene. gam + lambda carrying the same palindrome grow on both hosts and on a host deleted for the recB, C and D genes. These results suggest that the Gam protein of lambda, known to interact also with E. coli's recBCD protein, can interact wi...

Geodesic Acoustic Modes (GAM) are known to constitute a continuous spectrum due to radial inhomogeneities. The existence of a singular layer causes GAM to mode convert to short wavelength kinetic GAM (KGAM) via finite ion Larmor radius (FLR) and finite guiding-center drift-orbit-width (FOW) effects. The dispersion relation of GAM/KGAM with FLR/FOW as well as parallel electric field contribution...

BACKGROUND The conventional method for assessing the prevalence of Global Acute Malnutrition (GAM) in emergency settings is the 30 x 30 cluster-survey. This study describes alternative approaches: three Lot Quality Assurance Sampling (LQAS) designs to assess GAM. The LQAS designs were field-tested and their results compared with those from a 30 x 30 cluster-survey. METHODS Computer simulation...

The relationship between educational theories, game design and game development are used to develop models for the creation of complex learning environments. The Game Object Model (GOM), that marries educational theory and game design, forms the basis for the development of the Persona Outlining Model (POM) and the Game Achievement Model (GAM). POM provides researchers with a means to more easi...

BACKGROUND Macrolide-resistant isolates of Rhodococcus equi are emerging, prompting the search for clinically effective alternative antimicrobials. HYPOTHESIS The proportion of foals with ultrasonographic evidence of pneumonia presumed to be caused by R. equi that had a successful outcome when administered gallium maltolate (GaM) PO would not be more than 10% inferior (ie, lower) than that of...

Powerful CASE tools for Aspect Oriented System (AOS) are useful to improve the developer productivity and ensure syntactical correctness of the AOS model for effective system design. This paper has proposed a systematic approach to develop CASE tool for graph semantic based AOS model called, GAM, using meta-configurable environment called, Generic Modeling Environment (GME). Graph – semantic ba...

سفیدبالک‏ گلخانه Trialeurodes vaporariorum یکی از مهم‌ترین آفات محصولات گلخانه‏ای در سراسر دنیا می‏باشد. این پژوهش، زیست­شناسی و جدول زندگی دوجنسی سن- مرحله آفت روی سه محصول مهم شامل بادمجان، خیار گوجه‏فرنگی دمای 2±25 درجه‏ سلسیوس، رطوبت نسبی 10±65 درصد دوره نوری 16:8 ساعت (تاریکی: روشنایی)‏ مورد بررسی قرار گرفت. میانگین‏ها خطای معیار بر اساس روش بوت‏استراپ با یک‏صد هزار تکرار محاسبه شد. نتایج ...
