E proteins are conserved regulators of growth and development. We show that the Caenorhabditis elegans E-protein helix-loop-helix-2 (HLH-2) functions as a homodimer in directing development and function of the anchor cell (AC) of the gonad, the critical organizer of uterine and vulval development. Our structure-function analysis of HLH-2 indicates that dimerization drives its degradation in oth...

Solar panels are an alternative power generation system sourced from the absorption of solar energy. The energy absorbed will convert into a source electricity. panel's drives alternating current (AC) water pump. This study aims to determine performance AC pump by utilizing electrical panels. parameters measured voltage, current, and generated at varying times. used with capacity 100 WP were co...

This paper presents the movement dynamic of the train and the relationship between the speed of wheel and train, as well as a discussion about the concept of wheel slip. There are two different operation regions designated as creep and wheelspin areas for wheel slip. Creep and wheelspin areas have stable and unstable characteristics, respectively. Wheels and rails are constructed from iron, and...

This paper proposes a three phase transformerless AC/AC converter which can perform both buck and boost operations based on the voltage requirements. This AC/AC converter is mainly proposed for the three phase induction motor drives with the intention to reduce the high inrush current of the conventional motor used in industrial applications. The merits of the proposed AC/AC converter can be un...

During C. elegans development, LIN-12 (Notch) signaling specifies the anchor cell (AC) and ventral uterine precursor cell (VU) fates from two equivalent pre-AC/pre-VU cells in the hermaphrodite gonad. Once specified, the AC induces patterned proliferation of vulva via expression of LIN-3 (EGF) and then invades into the vulval epithelium. Although these cellular processes are essential for the p...
