in this study gill-net selectivity for alburnus chalcoides inhabiting the almus dam lake was estimated. experimental gill-net fishing was conducted using gill-net with 15 mm and 20 mm mesh-size, during october 2002 and september 2003. a total of 254 and 198 specimens of a. chalcoides were caught by gill-net with 15 mm and 198 with the 20 mm mesh-size, respectively. the total length of the fish ...

The quorum-sensing disrupter (5Z)-4-bromo-5-(bromomethylene)-3-butyl-2(5H)-furanone (furanone) of the alga Delisea pulchra was found to inhibit the swarming motility of Escherichia coli completely at 13 microg cm-2 (also at 20 microg ml-1) but did not inhibit its growth rate at 13-52 microg cm-2 or from 20 to 100 microg ml-1. Swimming was not inhibited by the furanone at 20-40 microg ml-1. In a...

Definition 5.2. Suppose one has a nonempty finite set = {C1, . . . ,Cm} of general consequence operators, each defined on a nonempty language Li, 1≤ i≤m. Define the operatorΠCm as follows: for any X ⊂ L1×···×Lm, using the projection pri, 1≤ i≤m, define ΠCm(X)= C1(pr1(X))×···×Cm(prm(X)). Theorem 5.3. The operator ΠCm defined on the subsets of L1 ×···×Lm is a general consequence operator and if, ...

In grassland ecosystems, N and P fertilization often increase plant productivity, but there is no concensus if fertilization affects soil C fractions. We tested effects of N, P and N+P fertilization at 5, 10, 15 g m-2 yr-1 (N5, N10, N15, P5, P10, P15, N5P5, N10P10, and N15P15) compared to unfertilized control on soil C, soil microbial biomass and functional diversity at the 0-20 cm and 20-40 cm...

Transverse momentum spectra of π at midrapidity are measured at high p T in p+p and p+Pb collisions at 158GeV/nucleon beam energy by the NA49 experiment. This study is complementary to our previous results on the same spectra from Pb+Pb collisions. The nuclear modification factors RA+A/p+p, Rp+A/p+p and RA+A/p+A as a function of p T are extracted and compared to RHIC measurements, thus providin...

در این تحقیق، لایه های نازک نیمرسانای اپتیکی سولفید قلع با ناخالصی مس و روی به روش اسپری پایرولیزیز بر روی بسترهای شیشه ای تهیه شده است. سپس، اثر تراکم ناخالصی مس، روی و هردو ناخالصی با هم بر روی خواص ساختاری، الکتریکی، ترموالکتریکی، اپتیکی و فوتورسانایی لایه های نازک sns بررسی شد. نتایج این بررسی ها نشان داد که تراکم بهینه برای ناخالصی مس ، روی و هردو ناخالصی با هم به ترتیب m 1/0، m 2/0 و m 2/...

livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. this research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of artemisia aucheri. hence, two rangelands of enclosure (shahtappeh-chah mahmood) and no enclosure (chiro) were chosen in sem...

An antimicrobial-surface kinetic test which maximizes probability of cell-to-surface contact has been developed. The measurement of rate of kill by a nonleaching antimicrobial surface is based on the number of surviving bacterial cells at specific times of exposure to various amounts of total treated surface area of test substrate. This method gives information for direct comparison of rate of ...

We present first results from the SCI-HI experiment, which we used to measure the all-sky-averaged 21 cm brightness temperature in the redshift range 14.8 < z < 22.7. The instrument consists of a single broadband sub-wavelength size antenna and a sampling system for real-time data processing and recording. Preliminary observations were completed in 2013 June at Isla Guadalupe, a Mexican biosphe...
