A rapid modified spot CAMP test using 183 clinical isolates of beta haemolytic streptococci was compared with the standard CAMP test described by Christie et al. The scheme of biochemical identification and serological confirmation was taken as reference method. The sensitivity of both tests was 100%, and the specificity of the rapid and standard tests was 96.8% and 88.9% respectively. The modi...

objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

The unrelenting threat of poaching has led to increased development of new technologies to combat it. One such example is the use of long wave thermal infrared cameras mounted on unmanned aerial vehicles (UAVs or drones) to spot poachers at night and report them to park rangers before they are able to harm animals. However, monitoring the live video stream from these conservation UAVs all night...

Esculin hydrolysis is a useful test in the differentiation of both gram-positive and gram-negative bacteria covering a wide spectrum of aerobes, facultative anaerobes, and anaerobes. Commonly utilized methods require a minimum of 18 h of incubation in broth or agar medium and utilize the production of a brown-black compound, due to the combination of ferric ions with the hydrolysis product escu...
