The tumor-promoting phorbol diester, 12-O-tetradecanoylphorbol-13-acetate (TPA), appears to induce a macrophagemimicking transformation of cells in human promyelocytic leu kemia continuous cultured lined HL-60, cells from normal hu man and chronic myeloid leukemia bone marrow, and cells from human acute leukemias. In the present experiments, peripheral blood and/or bone marrow nucleated cells f...

background: specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (escs) differentiation. in this study,the effects of bone morphogenetic protein 4 (bmp4) and mouse embryonic fibroblasts (mefs) co-culture system on germ cell differentiation from mouse escs were studied. materials and methods: cell suspension was prepared from one-day-old embryoi...

Nano-textured 4H-SiC homoepitaxial layers (NSiCLs) were grown on 4H-SiC(0001) substrates using a low pressure chemical vapor deposition technique (LPCVD), and subsequently were subjected to high temperature treatments (HTTs) for investigation of their surface morphology evolution and graphene growth. It was found that continuously distributed nano-scale patterns formed on NSiCLs which were abou...

This paper presents a simple model to describe experimental data on weak acid transport across planar bilayer lipid membrane separating two buffered solutions. The model takes into account multiple proton-transfer reactions occurring in the unstirred layers (ULs) adjacent to the membrane. Differential equations of the model are shown to be reduced to a set of nonlinear algebraic equations. Sinc...

Spermatogonial stem cells (SSCs, also called germline stem cells) are self-renewing unipotent stem cells that produce differentiating germ cells in the testis. SSCs can be isolated from the testis and cultured in vitro for long-term periods in the presence of feeder cells (often mouse embryonic fibroblasts). However, the maintenance of SSC feeder culture systems is tedious because preparation o...

This paper presents a novel hierarchical framework for real-time, network-admissible coordination of responsive grid resources aggregated into virtual batteries (VBs). In this context, VB represents local aggregation directly controlled loads, such as smart inverters, electric water heaters, and air-conditioners. The is achieved by solving an optimization problem to disaggregate feeder's desire...

Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity--housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix feeder per group. Data from 25 nonconsecutive 24-hr feeding cycles showed sows making several visits to the...

Front-end loaders extract sand and gravel (aggregate) from a pit and haul it to a feeder, which releases the aggregate onto a conveyor belt that is connected to a stockpile; the material is subsequently distributed to a processing plant. As mining progresses, the mining frontier moves farther away from the feeder, increasing loader cycle time. In turn, plant managers add loaders to maintain pro...

Abstract—The present work is an attempt to reduce the power loss and to improve the voltage profile on an existing 11 kV feeder by implementing different techniques. Simulations are performed using Mipower software on an existing 11 kV feeder (Aggarwal feeder) of industrial area Kapurthala. In this work effects of changing type of feeder are simulated to investigate the reduction in power loss ...
