Maximinus Thrax, Roma İmparatorluk tarihinde farklı özellikleriyle öne çıkan imparatorlarından biridir. Soylu bir aileden gelmediği gibi praetor praefectus makamına ulaşmış asker de değildir. Onun imparator olmasıyla beraber Severus ve Constantinus hanedanlıkları arasında askerlerin imparatorluk tahtına çıktığı dönem başlar. III. yüzyıl krizi olarak adlandırılan bu dönem, askeri kuvvetin ön pla...

Weed populations of sprangletop (Leptochloa chinensis) such as Kampung Permetang (KP), Kampung Pida-Tiga (KPT), Sungai Baru (SB1 and SB2), Kampung Pida-Empat (KPE), Singkir Yan (SY), Tanjung Dawai (TD), Dulang Besar (DB) and Kampung Bahagia (KB1 and KB2) were collected from paddy (Oryza sp.) growing areas in Kedah, Malaysia to identify resistant biotypes and their method of control. Weed biotyp...

We put stringent constraints for the first time on the dust properties in the circumburst medium of a gamma-ray burst (GRB) afterglow. This is based on the optical spectrum of GRB 020813 (z = 1.255), obtained with Keck I LRIS 4.65 h after the burst. From the absorption lines in the spectrum, we derive very high column densities for six heavy elements with different refractory properties. The re...

We have postulated that the catecholamine-synthesizing enzymes tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DBH), and phenylethanolamine N-methyltransferase (PNMT) are coded for by similar genes. To analyze the structural relationship of genes coding for these enzymes, we have cloned DNAs complementary (cDNA) to DBH and PNMT messenger RNAs (mRNAs). Using hybrid selection analysis to id...

BACKGROUND Thyroid absorption of iodine could be encumbered by nitrate drinking water when it is transported to the fetal thyroid gland. Therefore, nitrate potentially causes congenital hypothyroidism (CH) due to thyroid dysfunction. In this study, we have not only aimed at spatial determination of CH distribution and nitrate concentration (NC) existing in drinking water, but also we intended t...

A useful tool for distributed systems development is a time-outs manager. A time-outs manager is a software system that manages lists of “timeouts,” that is, objects that postpone a certain function call by a given amount of time. This feature may prove to be useful, as it allows transforming time-based events into nontime-based ones. A typical example is a time-out that on expiring sends an al...

Abstract Local and integral characteristics of heat transfer are obtained at varying the Reynolds number Re = 5500, 11000, distance between jets y/D 1.8, from to surface z/D 0.5-10 for system two identical impinging jets. It is found in experiments that effect an adjacent jet leads enhancement local large distances nozzles barrier. also shown increase increases transfer, and, same time, weakens...

BACKGROUND New regimens for hepatitis C virus (HCV) have shorter treatment durations and increased rates of sustained virologic response compared with existing therapies but are extremely expensive. OBJECTIVE To evaluate the cost-effectiveness of these treatments under different assumptions about their price and efficacy. DESIGN Discrete-event simulation. DATA SOURCES Published literature...
