چکیده بررسی الگوی مقاومت آنتی بیوتیکی و تشخیص ژن های کد کننده انتروتوکسین در staphylococcus aureus جدا شده از شیر مخازن تعدادی از گاوداری های صنعتی مشهد به کوشش: مهدی شریعتی فر هدف از این مطالعه ارزیابی میزان شیوع و مقاومت آنتی بیوتیکی سویه های استافیلوکوکوس اورئوس کواگولاز مثبت جدا شده از نمونه های شیر مخازن ذخیره، در طی سال های 1388 و 1389 در مشهد و بررسی میزان فراوانی ژن های کد کننده انت...
identification of spatial-temporal anomalies sea level pressure in iran was the main aim in this research. for this purpose six hourly data used from the to eastern longitude and to northern latitude. in this location, there are 825 pixels to geographical degree. therefore, database extent created. in this matrix, 825 are number of the pixels at that location and 90520 is number of six hourly s...
This study tested the effectiveness of a recently established sanctuary zone on Carnac Island (Western Australia) in reducing human disturbances to Australian sea lions (Neophoca cinerea). Several methods of recording behaviors were also tested to clarify their adequacy for detecting human disturbances. Observations made between March 2005 and September 2006 (98 observations over 16 days) indic...
In this study, minimum audible angles (MAAs) of aerial pure tones were measured in and compared between a northern elephant seal (Mirounga angustirostris), a harbor seal (Phoca vitulina), and a California sea lion (Zalophus californianus). Testing was conducted between 0.8 and 16 kHz in the elephant seal and 0.8 and 20 kHz in the harbor seal and sea lion in a hemi-anechoic chamber using a left/...
Hox gene collinearity relates the gene order of the Hox cluster in the chromosome (telomeric to centromeric end) with the serial activation of these genes in the ontogenetic units along the Anterior-Posterior embryonic axis. Although this collinearity property is well respected in bilaterians (e.g. vertebrates), it is violated in other animals. The A-P axis is established in the early embryo of...
One of the most degraded states of the Mediterranean rocky infralittoral ecosystem is a barren composed solely of bare rock and patches of crustose coralline algae. Barrens are typically created by the grazing action of large sea urchin populations. In 2008 we observed extensive areas almost devoid of erect algae, where sea urchins were rare, on the Mediterranean coast of Turkey. To determine t...
A species of sea anemone found in shallow water areas of southern Kaneohe Bay, Oahu, but never before reported from Hawaii, is described. It is identified as Actiniogeton sesere, previously recorded and described from the Torres Straits (Haddon and Shackleton 1893). HAWAII'S COELENTERATE FAUNA is poorly known and is in need of serious study. As I have discussed elsewhere (Dunn 1974), the single...
HeLa cells were transfected with recombinant DNAs containing the embryonic histone gene repeat of P.miliaris (h22) inserted in either orientation into a pBR-SV40 vector. After 2 to 3 days cytoplasmic RNA was analyzed for authentic sea urchin histone gene transcripts. The correct 5' termini of all five histone genes were detected, three (H2B, H2A and H3) at relatively high levels. In contrast, t...
In 1971, Schelling introduced a model in which families move if they have too many neighbors of the opposite type. In this paper, we will consider a metapopulation version of the model in which a city is divided into N neighborhoods, each of which has L houses. There are ρNL red families and ρNL blue families for some ρ < 1/2. Families are happy if there are ≤ ρ(c)L families of the opposite typ...
