Electromagnetic transient programs (EMTPs) are widely used for simulating electromagnetic in power systems. With the increasing interest integrated energy system (IES), it would be beneficial to extend scope of EMTP-type application multi-physics transients electrical and gas networks. An efficient accurate model pipeline is proposed EMTP simulation pneumatic transients. The split into a number...
Prostate cancer is the second cause of cancer in males. The prophylactic pelvic irradiation is usually needed for treating prostate cancer patients with Subclinical Nodal Metestases. Currently, the physicians decide when to deliver pelvic irradiation in nodal negative patients mainly by using the Roach formula, which gives an approximate estimation of the risk of Subclinical Nodal Metestases. I...
The earthquake focal mechanism is one of the essential parameters in understanding characteristics an source. For example, mainshock at Padang Lawas Regency and South Tapanuli on April 30, 2020, caused some damage to houses, schools, mosques, especially Regency. BMKG released first information that was 1.17N, 99.53E, 24 kilometers northwest Lawas, North Sumatra province, a depth 10 kilometers, ...
The transcription factor Foxh1 mediates Nodal signaling. The role of Foxh1 in left-right (LR) patterning was examined with mutant mice that lack this protein in lateral plate mesoderm (LPM). The mutant mice failed to express Nodal, Lefty2 and Pitx2 on the left side during embryogenesis and exhibited right isomerism. Ectopic introduction of Nodal into right LPM, by transplantation of left LPM or...
The glycosylphosphatidylinositol (GPI)-anchored proteoglycan Cripto binds Nodal and its type I receptor Alk4 to activate Smad2,3 transcription factors, but a role during Nodal precursor processing has not been described. We show that Cripto also binds the proprotein convertases Furin and PACE4 and localizes Nodal processing at the cell surface. When coexpressed as in early embryonic cells, Crip...
Cortical microinfarcts (CMIs) are microscopically identified wedge-shaped ischemic lesions that occur at or near the cortical surface and result from occlusion of penetrating arterioles. These microscopic lesions can be observed with high-resolution magnetic resonance imaging in aging brains and in patients with cerebrovascular disease. Recent studies have suggested that strategically located m...
A water distribution network is subjected to various abnormal conditions such as pipe breaks, pump failures, excessive demands etc. in the design period. Under such conditions, the network may not be able to meet required demands at desired pressures, and becomes deficient. Traditional network analysis assumes nodal demands to be satisfied and available nodal pressures are calculated. However, ...
Dog rose (Rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. It can be propagated under in vitro conditions. After removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on Murashige and Skoog medium (MS ...
In this paper we show how to extend the known algorithm of nodal analysis in such a way that, in the case of circuits without nullors and controlled sources (but allowing for both, independent current and voltage sources), the system of nodal equations describing the circuit is partitioned into one part, where the nodal variables are explicitly given as linear combinations of the voltage source...
the objective of the present study was to compare single segment and double segment intacs rings in the treatment of post-lasik ectasia. in this interventional study, 26 eyes with post-lasik ectasia were assessed. ectasia was defined as progressive myopia regardless of astigmatism, along with topographic evidence of inferior steepening of the cornea after lasik. we excluded those with a history...
