A puberal change in the secretory pattern of androgen was investigated in the rat. Using immature and adult rats which received an acute human chorionic gonadotrophin(HCG) stimulation, androstenedione and testosterone were measured both in the testicular venous blood(TVB) and in the testis by means of gaschromatography after preliminary separation by paperchromatography. In contrast to the adul...

In this study, histamine level and some other quality parameters have been examined in anchovy, horse mackerel, mackerel, rainbow trout, mirror carp and barbel consumed as fresh in Elazig. For this purpose, fish samples were obtained 15 day intervals between September 2003 and April 2004 and they were filleted. Histamine, TMA-N, TVB-N and pH values were examined in these fillets.Mean histamine ...

In this paper we provide an analysis of monotonicity properties for linear multistep methods. These monotonicity properties include positivity and the diminishing of total variation. We also pay particular attention to related boundedness properties such as the total variation bounded (TVB) property. In the analysis the multistep methods are considered in combination with suitable starting proc...

Mục tiêu: Đánh giá kết quả thuật phẫu nội soi hoàn toàn ngoài phúc mạc (Total Extraperitoneal - TEP) đặt lưới nhân tạo 3D điều trị thoát vị bẹn hai bên ở người lớn. Đối tượng và phương pháp: Nghiên cứu mô tả 60 bệnh (BN) trên 18 tuổi được chẩn đoán là (TVB) bằng TEP tại Bệnh viện Thanh Nhàn, từ tháng 01/2017 đến 11/2020. Kết quả: BN với 63,3% TVB trực tiếp, 36,7% gián tiếp. Thời gian đau sau mổ...

Bu çalışmada, farklı oranlarda (%4 ve %8) keten çiya tohumu ile zenginleştirilmiş yayın balığı (Silurus glanis) köftelerinin bazı kalite kriterlerinin incelenmesi amaçlanmıştır. Balık köfteleri depolamanın belirli günlerinde (1, 7 14. gün) toplam aerobik mezofilik bakteri (TAMB), psikrotrofik bakteri, maya-küf, tiyobarbitürik asit (TBARS), uçucu bazik azotu (TVB-N), pH duyusal parametreleri yön...

The fresh mackerel was frozen using four different quick-freezing methods, such as refrigerator freezing, quick freezer spiral tunnel freezing and plate freezing. Water retention, color, texture, electrical conductivity, total volatile base nitrogen (TVB-N), K value, malondialdehyde (MDA), sulfhydryl group protein secondary structure were used physicochemical indicators to evaluate the changes ...

Total Volatile Base Nitrogen (TVB-N) and Trimethylamine (TMA-N) contents of Vetki (Lates calcarifer) were investigated following Conway’s Microdiffusion technique at 4 hour interval in Fish Quality Control Laboratory, Fisheries Marine Resource Technology Discipline, Khulna University. Observed TVB-N TMA-N value did not vary significantly among different size classes. At fresh condition, content...

Exploitation of GPS based EGNOS and Galileo for safe train position determination within the modernised European Train Control System (ETCS) belongs currently among main priorities of the European joint GNSS and rail R&D. It is obvious that only the effective use of the aviation EGNOS SoL service according to CENELEC railway safety standards has the potential to replace costly ETCS track-side b...

Brain function is thought to emerge from the interactions among neuronal populations. Apart from traditional efforts to reproduce brain dynamics from the micro- to macroscopic scales, complementary approaches develop phenomenological models of lower complexity. Such macroscopic models typically generate only a few selected-ideally functionally relevant-aspects of the brain dynamics. Importantly...
