This paper presents the Zero-Voltage Switching (ZVS) performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. Switching transitions of the transistor occurring in favorable conditions such as device zero-voltage or zero-current is called as soft-switching. The benefits of soft-switching are reduced switching losses, switch stress, low electromagneti...
Mit dem neuen Tierschutzgesetz, das in Deutschland vor wenigen Monaten in Kraft getreten ist, kommen auf die Behorden neue Aufgaben zu. Auch die Verwaltungsvorschrift zur Durchfiihrung des Tierschutzgesetzes muB deshalb erganzt werden. Das Bundesministerium fur Ernahrung, Landwirtschaft und Forsten hat dazu Ende Juli einen ersten Entwurf vorgelegt. Das Bundesrninisterium hat die Gelegenheit nic...
We investigated the nutritional condition of larval fishes caught in daily ichthyoplankton hauls in the ‘Helgoland Roads’ (54° 11.18’ N and 07° 54.00’ E) from February to June 2004. We concentrated on larvae of dab Limanda limanda and lesser sandeel Ammodytes marinus in order to compare early life stages of iteroparous and nearly semelparous fish. We analysed length, weight and RNA:DNA ratios a...
زمینه مطالعه: آلودگی به سارکوسیستیس یکی از شایع ترین عفونت‌های تک یاخته ای مشترک بین انسان و دام می‌باشد که توسط گونه‌های مختلف سارکوسیستیس ایجاد می‌شود. هدف: با توجه به اهمیت بهداشتی این انگل، در این مطالعه میزان آلودگی به کیست‌های ماکروسکوپی و میکروسکوپی سارکوسیستیس در گاو و گوسفند ذبح شده در کشتارگاه شهریار مورد بررسی قرار گرفت. مواد و روش کار: در این مطالعه 138 لاشه گاو و 138 لاشه گوسفند بط...
The current-fed dual active bridge (CF-DAB) dc–dc converter gains growing applications in photovoltaic (PV) and energy storage systems due to its advantages, e.g., a wide input voltage range, a high step-up ratio, a low input current ripple, and a multiport interface capability. In addition, the direct input current controllability and extra control freedom of the CF-DAB converter make it possi...
A potent VEGF inhibitor with novel antibody architecture and antigen binding mode has been developed. The molecule, hereafter referred to as VEGF dual dAb a (domain antibody), was evaluated in vitro for binding to VEGF and for potency in VEGF driven models and compared with other anti-VEGF biologics that have been used in ocular anti-angiogenic therapeutic regimes. VEGF dual dAb is more potent ...
This paper presents an interface system based on the Dual Active Bridge (DAB) converter for Photovoltaic (PV) arrays. Two control strategies are proposed for the DAB converter to harvest the maximum power from the PV array. The first strategy is based on a simple PI controller to regulate the terminal PV voltage through the phase shift angle of the DAB converter. The Perturb and Observe (P&O) M...
Melanin may interfere with immunohistochemical staining. The goal of this study was to investigate the effects of trichloroisocyanuric acid (TCCA) bleaching, potassium permanganate bleaching, and potassium dichromate bleaching on melanin, tissue antigen, and 3,3'-diaminobenzidine (DAB) using melanin-containing and melanin-free tissue samples. Our results demonstrated that all 3 bleaching method...
A potent anti-vascular endothelial growth factor (VEGF) biologic and a compatible delivery system were co-evaluated for protection against wet age-related macular degeneration (AMD) over a 6month period following a single intravitreal (IVT) injection. The anti-VEGF molecule is dimeric, containing two different anti-VEGF domain antibodies (dAb) attached to a human IgG1 Fc region: a dual dAb. The...
The electronic structures and the spin density distributions of the group 13 1,4-diaza(1,3)butadiene (DAB) radicals [(R-DAB)2M]*, [(R-DAB)MX2] and {[(R-DAB)MX]2}** (M = Al, Ga, In; X = F, Cl, Br, I; R = H, Me, tBu, Ph) are studied using density functional theory at both non-relativistic and relativistic levels of theory. The calculations demonstrate that all systems share a qualitatively simila...
