We present sub-arcsecond resolution ALMA imaging of the CO(3-2) emission in two $z\sim2.5$ heavily reddened quasars (HRQs) - ULASJ1234+0907 and ULASJ2315+0143 their companion galaxies. Dynamical modeling resolved velocity fields enables us to constrain molecular gas morphologies host galaxy masses. Combining new data with extensive multi-wavelength observations, we are able study relative kinem...

We continue the study, initiated in (J. Eur. Math. Soc. (JEMS) 20 (2018) 199–257), of localization transition a lattice free field ϕ=(ϕ(x))x∈Zd, d≥3, presence quenched disordered substrate. The substrate affects interface at spatial sites which height is close to zero. This corresponds Hamiltonian ∑x∈Zd(βωx+h)δx, where δx= 1[−1,1](ϕ(x)), and (ωx)x∈Zd an i.i.d. centered field. A takes place when...

conclusions this study showed that multiple β-lactamases can be produced in burn isolates. this suggests that use of cephalosporins and carbapenems should be restricted in burn isolates to minimize the development and spread of these multidrug resistant pathogens. results there was 99% resistance to carbenicillin, and ticarcillin, 98% to cotrimoxazole, 96% to ciprofloxacin, and aztreonam, 95% t...

سفید بالک گلخانه Trialeurodes vaporariorum (Hom.: Aleyrodidae) در اکثر مناطق دارای اهمیت اقتصادی بوده و دشمنان طبیعی مختلفی روی آن فعالیت می‌کنند که در این میان نقش زنبور Encarsia formosa (Hym.: Aphelinidae) انکارناپذیر است. سموم شیمیایی دارای اثرات متفاوتی روی جنبه‌های مختلف زیست‌شناسی دشمنان طبیعی می‌باشند. در این تحقیق اثرات حشره‌کش‌های بوپروفزین، پیری‌پروکسی‌فن و فن‌پروپاترین روی ترجیح بین ...

background :   ampc β-lactamases are important cephalosporinases chromosomally encoded in many of enterobacteriaceae and a few other organisms where they mediate resistance to cephalothin, cefazolin, cefoxitin and penicillins. the six different families of plasmid-mediated ampc β-lactamases have been described, but no phenotypic test can discriminate among them. ampc multiplex pcr has been succ...
