The role of the Escherichia coli iron-regulated gene homologue adhesin (Iha) in the pathogenesis of urinary tract infections (UTIs) is unknown. We performed a series of complementary analyses to confirm or refute the hypothesis that Iha is a virulence factor in uropathogenic E. coli. Fecal E. coli isolates exhibited significantly lower prevalences of iha (range, 14 to 22%) than did clinical iso...

با توجه به عدم­‌قطعیت‌های حاکم بر پروژه‌های عمرانی و تفاوت بارز آن‌ها صنایع خدماتی تولیدی از منظر محدوده زمان‌بندی کار، عوامل محیطی چالش‌های اجرایی، پیمانکاران کارفرمایان همواره اختلافات دعاوی قراردادی مواجه هستند. در چنین شرایطی، پژوهشی موضوع ضروری است. هدف این پژوهش، شناسایی مرتبط فرآیندهای طرح ادعا رویه مواجهه چالش‌ها راستا، لوایح ادعایی ارزیابی شدند. روش پژوهش به‌صورت کمّی ـ کیفی مشتمل بررسی...

The study aimed to evaluate the yield components and physiological quality of rice seeds produced, obtained from coated with rusk ash kaolin®. Treatments consisted coating two sources silicon (silicate aluminum-70% SiO2 (kaolin® husk ash- 95% SiO2) at doses 0; 30; 60; 90 120 g.100 kg-1 seed. Yield were evaluated: Seed per plant, number panicles plant plant. subjected germination, first ...

Measurement of soil CO2 efflux using a non-flow-through steady-state (NFT-SS) chamber with alkali absorption of CO2 by soda lime was tested and compared with a flow-through non-steady-state (FT-NSS) IRGAmethod to assess suitability of using soda lime for field monitoring over large spatial scales and integrated over a day. Potential errors and artifacts associated with the soda lime chamber met...

The objective with the work was to evaluate, during storage, rice seeds physical and physiological quality, cultivar IRGA 424 RI, dried different drying air temperatures. For such, were harvested a moisture content of 22%. Then, they subjected in cross-flow dryer, operating an intermittent system using 55 65 ºC After, samples containing 50 kg stored PP Woven Bags for 240 days. After every 60 da...

Studies that simulate recurrent drought events with subsequent episodes of rehydration better reflect natural conditions and allow visualization differential acclimatization responses resulting from memory tolerance mechanisms. Piper aduncum tuberculatum were grown in a greenhouse subjected to three successive cycles rehydration. After suspending irrigation, gas exchanges measured da...

Irrigated rice cultivation is an important source of greenhouse gas emissions. Among the main gases, there are carbon dioxide, methane, and nitrous oxide, with emission each varying according to management crop, cultivar irrigation management. In this context, present study aimed quantify partial global warming potential (pGWP) measured by CH4 N2O emissions in conventional hybrid cultivars unde...

Abstract The aim of this study was to evaluate the effect potato boiling on correctness cultivar discrimination. research performed in an objective, inexpensive and fast manner using image analysis technique. textures outer surface slice images raw boiled potatoes were calculated. discriminative models based a set selected from all color channels ( R , G B L b X Y Z U V S ), for spaces individu...
