Model-driven engineering (MDE) is a branch of software engineering that aims at improving the productivity, quality, and cost-effectiveness of software development by promoting models and model transformations as the primary assets in software development. Models can be specified using general-purpose languages like the Unified Modeling Language (UML). However, to fully unfold the potential of ...

The problem of content-based image searching has received considerable attention in the last few years. Thousands of images are now available on the internet, and many important applications require searching of images in domains such as E-commerce, medical imaging, weather prediction, satellite imagery, and so on. Yet, content-based image querying is still largely unestablished as a mainstream...

few, if any, studies have investigated the effect of professional experience as a rater variable and type of assessment as a task variable on raters’ criteria in the assessment of speech acts. this study aimed to explore the impact of nonnative teachers’ professional experience on the use of criteria in monologic and dialogic assessment of 12 role-plays of 3 apology speech acts. to this end, 60...

Background and Objective: Antimicrobial peptides have attracted significant attention in recent decades because of their properties, such as rapid bactericidal effects, having a wide spectrum of activity, and a rare development of drug resistance. The purpose of this study was to examine the antibacterial activity of a peptide derived from the lactoferrin isolated from camel milk against Staphy...

In mammals, biological rhythms are driven by a master circadian clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus. Recently, we have demonstrated that in the camel, the daily cycle of environmental temperature is able to entrain the master clock. This raises several questions about the structure and function of the SCN in this species. The current work is the first neuroana...

This review summarizes recent developments in camel reproduction, and it describes characteristics of the ovarian follicular wave cycle and exogenous hormonal control of ovulation and luteolysis. In addition, an account is given of the developments in assisted reproductive technologies in camels such as methods for collection, transfer, and deep-freezing of embryos and semen. Details of recent ...

In this paper we describe CARPET, a parallel programming language based on the cellular automata model. CARPET is the language used for programming cellular algorithms in the CAMEL environment. CAMEL is an environment designed to support the development of high performance applications in science and engineering. It offers the computing power of a highly parallel computer, hiding the architectu...

The effect of various animal wastes on growth and reproduction of an epigeic earthworm Eisenia foetida was studied under identical laboratory conditions. For each waste, viz., cow, buffalo, horse, donkey, sheep, goat and camel, five hatchlings per 100 g of waste were inoculated and monitored for biomass gain, mortality, sexual maturity, cocoons production periodically for 15 weeks. No mortality...

The dsRNA binding protein (RBP) encoding gene of parapoxviruses (PPVs) from the Dromedary camels, inhabitating different geographical region of Rajasthan, India were amplified by polymerase chain reaction using the primers of pseudocowpoxvirus (PCPV) from Finnish reindeer and cloned into pGEM-T for sequence analysis. Analysis of RBP encoding gene revealed that PPV DNA from Bikaner shared 98.3% ...

Semen was collected from six dromedary camels using artificial vagina during rutting season. Liquefaction of the viscous semen occurred in 23.89 ± 1.49 h. During liquefaction, proteins with molecular masses of 24.55 kDa and 22.07 kDa appeared in conjunction with the disappearance of intact 26.00 kDa protein after 18-24 h. These proteins were identified as β-nerve growth factors (β-NGFs) in liqu...
