Solar photovoltaic (PV) arrays are providing an increasing fraction of global electrical demand, with an accelerating rate of new installations. Most of these employ conventional glass-fronted panels, but this type of PV array does not satisfy applications that require a light-weight, flexible PV generator. An option discussed in this article is to consider textiles for such solar cell substrat...

In this paper, we prove that S 2 can prove consistency of PV−, the system obtained from Cook and Urquhart’s PV [3] by removing induction. This apparently contradicts Buss and Ignjatović [2], since they prove that PV 6⊢ Con(PV−). However, what they actually prove is unprovability of consistency of the system which is obtained from PV− by addition of propositional logic and BASICe-axioms. On the ...

در این مقاله یک تکنیک کلیدزنی قابل اطمینان و مؤثر به منظور بهبود اعوجاج هارمونیک کل، بدون استفاده از هیچ مدار فیلتری پیشنهاد می گردد. اعوجاج هارمونیکی کل اثرات مضری بر روی تجهیزات الکتریکی دارند و بطور ناخواسته می تواند باعث افزایش جریان در سیستم های قدرت و در راستای آن افزایش دما در هادی خنثی و ترانسفورماتورهای توزیع شود. این روش قادر خواهد بود هارمونیک انتخابی مرتبه پایین ولتاژ خط، در خروجی ا...

Voltage boosting from CMOS photovoltaic device (PV) is achieved by implementing multiple PV units on single CMOS chip and are series connected by an external integrated passive device. Localized substrate removal process is developed to electrically isolate the PV units. Four-cell cascaded CMOS PV module provides an open-circuit voltage of 2.05 V while maintaining its superior PV performance.

ABSTRACT Common bacterial blight (CBB), caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans, is one of the most important diseases of common bean (Phaseolus vulgaris) in East Africa and other bean-growing regions. Xanthomonad-like bacteria associated with CBB in Malawi and Tanzania, East Africa, and in Wisconsin, U.S., were characterized based on brown pigm...

Plasmalemma vesicle protein-1 (PV-1) is an integral membrane protein associated with endothelial cell caveolae and fenestrae. Since endocrine glands are enriched with fenestrated endothelium, we examined the distribution of PV-1 mRNA and protein in endocrine glands and determined its cellular localization. A single transcript was detected by RT-PCR in all endocrine glands examined. A synthetic ...

BACKGROUND Circumferential pulmonary vein (PV) isolation for atrial fibrillation (AF) is occasionally difficult to achieve because electrical breakthrough sites (EBSs) between the left atrium (LA) and PVs cannot be identified during ablation especially in the carina regions. METHODS The left PVs (Lt.PVs) of 60 AF patients and the right PVs (Rt.PVs) of 37 patients undergoing PV isolation were ...

با توجه به نیاز روزافزون جهان به انرژی و همچنین محدود بودن منابع انرژی فسیلی، ضرورت استفاده از انرژیهای تجدیدپذیر را بیش از پیش نمایان می کند. یک پیشنهاد جهت غلبه بر تناوبی بودن منابع انرژی تجدیدپذیر نظیر خورشید و باد،گسترش سیستم انرژی هیبریدی است که در آن می توان انرژی الکتریکی اضافی را تبدیل و ذخیره کرده و سیستمی با قابلیت اطمینان بهتری که برای کاربردهای مستقل از شبکه مناسب باشد، فراهم نمود. ...

Thyroid hormone (T(3)) acts in chondrocytes and bone-forming osteoblasts to control bone development and maintenance, but the signaling pathways mediating these effects are poorly understood. Thrb(PV/PV) mice have a severely impaired pituitary-thyroid axis and elevated thyroid hormone levels due to a dominant-negative mutant T(3) receptor (TRβ(PV)) that cannot bind T(3) and interferes with the ...

Solar energy is one of the most abundant sources of renewable energy for the future. This solar energy can be extracted by PV system. Many methods for PV installation are carried out, such as roof top PV system, dam top PV system; floating PV, canal top PV system etc. In canal top system, PV panels are placed above the water canal which saves installation area and reduces evaporation loss. The ...
