in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
Abstract. General circulation models (GCMs) are the primary tools for evaluating possible impacts of climate change; however, their results coarse in temporal and spatial dimensions. In addition, they often show systematic biases compared to observations. Downscaling bias correction model outputs is thus required local applications. Apart from computationally intensive strategy dynamical downsc...
The cellular events that govern patterning during animal development must be precisely regulated. This is achieved by extrinsic factors and through the action of both positive and negative feedback loops. Wnt/Wg signals are crucial across species in many developmental patterning events. We report that Drosophila nemo (nmo) acts as an intracellular feedback inhibitor of Wingless (Wg) and that it...
Wingless, the Drosophila homologue of the proto-oncogene Wnt-1, encodes a secreted glycoprotein that regulates differentiation and proliferation of nearby cells. Here we report on the biochemical mechanism(s) by which the wingless signal is transmitted from cell to cell. When expressed in S2 cells, the majority (approximately 83%) of secreted wingless protein (WG) is bound to the cell surface a...
Accurate estimation of suspended sediment in rivers is very important from different aspects including agriculture, soil conservation, shipping, dam construction and aquatic research. There are different methods for suspended sediment estimation. In the present study to evaluate the ability of time-series models including Markov and ARIMA in predicting suspended sediment and to compare their re...
Wingless (Wg) is a secreted ligand that differentially activates gene expression in target tissues. It belongs to the Wnt family of secreted signaling molecules that regulate cell-to-cell interactions during development. Activation of Wg targets is dependent on the ligand concentration in the extracellular milieu; cellular mechanisms that govern the synthesis, delivery and receipt of Wg are ela...
1-Introduction Climate change refers to any significant change in the existing mean climatic conditions within a certain time period (Jana and Majumder, 2010; Giorgi, 2006). Earth's climate change through history has happened (Nakicenovic et al., 2000; Bytnerowicz et al., 2007). 2-Materials and methods In this study, daily precipitation and daily maximum (Tmax) and daily minimum (Tmin) tempera...
In Drosophila wing imaginal discs, the Wingless (Wg) protein acts as a morphogen, emanating from the dorsal/ventral (D/V) boundary of the disc to directly define cell identities along the D/V axis at short and long range. Here, we show that high levels of a Wg receptor, Drosophila frizzled 2 (Dfz2), stabilize Wg, allowing it to reach cells far from its site of synthesis. Wg signaling represses ...
Lipid-modified Wnt/Wingless (Wg) proteins can signal to their target cells in a short- or long-range manner. How these hydrophobic proteins travel through the extracellular environment remains an outstanding question. Here, we report on a Wg binding protein, Secreted Wg-interacting molecule (Swim), that facilitates Wg diffusion through the extracellular matrix. Swim, a putative member of the Li...
a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...
