In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...

In this paper we investigate the sub-channel assignment and power control to maximize the total sum rate in the uplink of two-cell network. It is assumed that there are some sub-channels in each cell which should be allocated among some users. Also, each user is subjected to a power constraint. The underlying problem is a non-convex mixed integer non-linear optimization problem which does not h...

Arm grooves of star-fish have mesenchymal stem cells derived from adipose tissue cell. Widespread studies have shown that stem cells derived from adipose-derived mesenchymal stem cell from bone marrow have many similarities in terms of the ability to differentiate into a variety of tissues. Most of the animals live in warm and shallow waters and the waters of this feature is that it is low in d...

In this paper, a method is introduced which reduces the harmonicdistortion of the inverter output current, connecting the fuelcell to the AC load. Using FUZZY LOGIC-PI (FLPI), the controllingmethod is engaged in optimum tuning of the PI controllercoefficients of this converter. This converter has only one DC-ACboost inverter and simultaneously has the task of increasingvoltage level and generat...

objective: research related to induce pluripotent stem (ips) cell generation has increased rapidly in recent years. six transcription factors, namely oct4, sox2, c-myc, klf4, nanog, and lin28 have been widely used for ips cell generation. as there is a lack of data on intra- and inter-networking among these six different transcription factors, the objective of this study is to analyze the intra...
