Elongation factor 1A is a highly conserved protein that participates in translation. We report the occurrence of two genes homologous to the eukaryotic Elongation Factor 1A in Bradysia hygida and describe the partial cloning and characterization of the B. hygida eukaryotic Elongation Factor 1A-F1 (BheEF1A-F1) gene. The pattern of BheEF1A-F1 expression in the salivary gland at the end of the fou...

The Unified Matrix Hypothesis (UMH) proposed that genomes may be organised in space, and genomic domains be transcribed in specific sectors of the nucleus [1]. The UMH generalised for normal types of interphase cells, the pattern of Ectopic Pairing observed in drosophila salivary gland cells. The recent publication of the 3D structure of the yeast genome [2] is clear confirmation in lower eukar...

Male meiosis in Trichosia pubescens (Sciaridae) was investigated by means of serial section electron microscopy and immunofluorescence light microscopy. From earlier studies of another sciarid fly, Sciara coprophila (Phillips (1967) J. Cell. Biol. 33, 73-92), it is known that the spindle poles in sciarid spermatogonia are characterized by pairs of 'giant centrioles', ring-shaped organelles comp...

چکیده: بیش از 699 نمونه ی قارچ کلاهک دار از برخی ازمناطق استان کرمانشاه، طی سال های 1389 و 1390 جمع آوری و فون حشرات و کنه های مرتبط با آن ها بررسی شد. شناسایی حشرات توسط متخصصین مربوطه در خارج از کشور و شناسایی کنه ها توسط متخصصین داخل کشور انجام شد. نتیجه ی این بررسی منجر به شناسایی هشت خانواده از راسته ی دوبالان شامل (sciaridae، phoridae، cecidomyiidae، sphaeroceridae، scatopsidae، mycetophi...

A new design of interception trap is presented based on a combination of features ofwindow and Malaise traps. The trap has been developed for study of the canopy faunas of rainforest trees, specifically Argyrodendron actinophyllum. Five such traps have been operated in SE Queensland for a year with catches being removed weekly. Coleoptera, Nematocera, Homoptera and Hymenoptera were the most abu...

The capability of the AARE modular code system and JEF-1 based nuclear data libraries to analyse LWHCR lattices is investigated by calculating the wet and dry cells of the PROTEUS-LWHCR Phase II experiment. The results are compared to those obtained using . several celI codes. Main features of AARE, such as the self-sbelding of resonance cross sections in the whole energy range, the generation ...

–While email is one of the fastest form of communication, the user is frequently faced with receiving unsolicited emails called spams. Nonspam mails are known as hams which are legitimate mails. It is practically very difficult to perfectly classify a mail into spam or ham basing on the content or subject of the mail. Several statistical methods are available which classify mails with some chan...
