Effects of Direct and Conventional Planting on Soil Properties and Yield Characteristics of Second Crop Maize

Conventional tillage CT , a commercial direct planter DP1 , and a modified direct planter DP2 were used in this study to determine the performance of DP compared to CT and DP1 in second crop maize after winter wheat. Experiments were conducted with six replications through complete randomized block design. Average seed spacing was about 18 cm and the quality of feed index was about 90% in all methods. Multiple index was the smallest 0.56% in CT, suggesting best horizontal seed distribution whereas DP1 had the highest rate 3.89% . Variation about the mean seed spacing was less than the upper limit of 29% in precision in spacing in all cases. The adjusted seeding depth was 6.0 cm in CT 5.99 cm with the best placement and the poorest placement was found in DP2 2.90 cm . Seed depth distribution was different in the three cases

The genetic history of the Southern Arc: a bridge between West Asia and Europe

By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe

Veils-free DRY (ICP) etching of gold films with a vertical sharp sidewall

This paper presents a new method of dry etching for thin Au films in a dual frequency inductively coupled plasma (ICP) system on Si substrates to prevent veils of etched Au particles over the sidewall and to obtain vertical sharp sidewalls of patterned Au films. After optimizing ICP system process parameters, deposition of a thin Ti film on top of the Au film has been examined on the redeposition of etched Au particles over the sidewalls. The results show that depositing a thin Ti film on top of the Au film can prevent the redeposition of etched Au particles on the sidewall, and also a vertical sharp sidewall of the Au film can be obtained even if a thicker Au film with realization of this new method. Depending on the results of this work, we propose a new method that eliminates the redeposition of the etched Au particles on the sidewall for obtaining a vertical sharp sidewall of Au film with the dry Au etch process

Pelvik Cerrahlar için Temel Klinik Retroperitoneal Anatomi

Basic anatomical knowledge should be improved during residency period with clinical practice. Especially pelvic surgeons; obstetricians, gynecologists, gynecological oncologists, urologists and general surgeons must have an advanced level practise of retroperitoneal anatomy to gain surgical skills. Retroperitoneal topographic anatomy, retroperitoneal vasculature, ureteric dissection and pelvic avascular spaces are the precise points during pelvic surgery.PubMedScopusTr-Dizi

Adenoid Basal Carcinoma of Uterine Cervix: A Case Report

Adenoid basal carcinoma of uterine cervix is a very rare entity that has been reported less than 100 cases in the literature. Although the origin of the carcinoma is controversial; the multipotential basal cell layer of cervix is the believed part for tumor growth. A 54 years-old white postmenopausal woman was referred to our clinic with the complaint of postmenopausal bleeding. Her pelvic examination revealed a tumor lesion of 1.5cm on the ectocervix. Her cervical and endometrial biopsies revealed an epithelial carcinoma and we performed a radical hysterectomy with bilateral salpingo-oophorectomy and bilateral pelvic-paraaortic lymph node dissection. The final pathology result revealed adenoid basal carcinoma. Distinction of adenoid basal carcinoma from adenoid cystic carcinoma and other aggressive basaloid pathologies of cervix is important for the clinical management of patients since adenoid basal carcinoma is benign in behaviour despite being a carcinoma
