combining ability and heterosis were studied in a 6×6 partial diallel cross during 2007-2009 to see the nature of gene action in cucumber (cucumis sativus l.). analysis of variance revealed high significant differences among all the f1 hybrid means and among their respective six parental values for all the traits examined. the mean squares attributed to general combining ability (gca) and speci...

Introduction: A new method based on image registration technique and an intelligent correlation model to calculate. The present study aimed to propose inter- and intra-fraction motion errors in order to address the limitations of conventional Patient positioning methods. Material and Methods: The configuration of the markerless method wa...

The mashup paradigm allows end users to build their own web applications consisting of several components in order to fulfill specific needs. Thereby, communicating on a non-technical level with non-programmers as end users is crucial. It is also necessary to assist them, for instance, by explaining inter-widget communication and by helping to understand a mashup’s functionality. However, preva...

House mice (Mus musculus domesticus) in Tunisia consists of two races, one carries the 40-acrocentric standard karyotypes and the other one is a robertsonian race (2n=22) homozygous for nine centric fusions (Rb). The F1 hybrids between the two chromosomal races showed a significant decrease in reproductive success and litter size. Such results can be related to the formation of meiotic trivalen...

Interspecific hybrid embryos are useful models for the study of maternal-fetal interactions, transmission pattern of species-specific markers and parental contributions to growth and developmental potential of pre-attachment embryos. In an attempt to investigate the possibility of producing hybrid embryos of domestic cattle (Bos taurus) and water buffalo (Bubalus bubalis), cattle oocytes were e...

multiple people detection and tracking is a challenging task in real-world crowded scenes. in this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. we have detected objects with deformable part models and a visual background extractor. in the tracking phase we have used a combination of support vector machine (svm) person-specific classifie...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...

production of high yielding hybrid cultivars is among the main objectives of breeding programs in sunflower and on evaluation of the combining ability of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. this study was conducted to investigate the general and specific combining ability and the mode of inheritance for agronomic and seed q...

The agents of cryptococcosis C. neoformans and C. gattii are important agents of meningoencephalitis in immunocompromised and immunocompetent hosts, respectively. They are grouped into eight major molecular types, VNI-VNIV for C. neoformans and VGI-VGIV for C. gattii. These major molecular types differ in their host range, epidemiology, antifungal susceptibility and geographic distribution. To ...
