Design and Simulation of Speed Control of DC Motor by  Artificial Neural Network Technique

This paper proposes the artificial neural network based controller for speed control of a separately excited DC motor. The Artificial Neural Network controller allows controlling both type of systems i.e. linear and non-linear system by training the network. So it is a novel approach to study and a broad research area.

Relevance of Red Cell Distribution Width (RDW)  Determination in Stroke: A Case Control Study

BACKGROUND: Stroke is an important cause of disability and death. Recently several studies have claimed that RDW is a good predictor of outcome in stroke. As RDW is a complete blood count (CBC) parameter that is routinely determined in clinical laboratories, these studies important implications in patient management in developing countries. The present study was taken up to find out if RDW can be used as an inexpensive biomarker for stroke. MATERIALS AND METHODS: A case-control study involving 52 test subjects and 54 matched controls was conducted. RDW values were determined in test and control groups, compared and statistically analysed. RESULTS & CONCLUSIONS: Significantly higher mean values for RDW (p <0.001) are observed in stroke patients compared to reference population. RDW values higher than 13.0 are associated with several fold increase in the risk of stroke (odds ratio 4.1; p value <0.006); but, the level of RDW does not show a linear relationship

E.coli: As an Alternate Model for Phototoxicity  Assessment of Drugs

Phototoxic and photoallergic reactions represent skin reactions to the sun, in the presence of photoactive chemicals applied on the skin or taken systemically. They have a highly polymorphic clinical presentation – photo contact urticaria, eczema on sun-exposed areas sometimes with erythema multiforme, exaggerated sunburn, linear phytophotodermatitis, pseudoporphyria, photoonycholysis, dyschromia, and lupus erythematosus. Also, skin cancers are increasingly associated with exposure to photoactive chemicals. There is a geographical and timely variation in the responsible agents, but they are mostly furocumarins from plants, UV filters in sunscreens and cosmetics, and drugs (NSAIDs, antimicrobials, phenothiazines, amiodarone, etc.) Three drugs like Chloramphenicol, Norflox, and Kucil(Fluorouracil) were tested for Phototoxic effect procured from local market and check the ph and absorption spectra and note and solubility of test drug was tried out through different solve

The Reliability of Musculoskeletal Ultrasound Video  Tracking of Muscle and Tendon Displacement

Lateral epicondylalgia [LE] is most common cause of elbow pain attributed to abnormalities in the extensor carpi radialis and extensor digitorum communis [EDC]. Quantifying the linear displacement using musculoskeletal ultrasound and the Motion Tracking Analysis Program [MTAP] may be useful in characterizing the abnormalities found in elbows with LE. This study investigated the reliability of the operators [i.e. sonologist and sonographer] and the reader [i.e. physiotherapist] in procuring and analyzing ultrasound videos using MTAP.

Scirj-Enhancement of Photorefractive Two-Beam Coupling in KNbO3

A theoretical study has been done to investigate the significant enhancement of the photorefractive and photovoltaic effects of a new co-doped potassium niobate crystal (KNbO3: Fe: Ag) as compared to the result obtained for singly doped potassium niobate crystals. The co-doped Ag impurity enters the K site, rather than the typical Nb site, thus changing the local field in the lattice. It is believed that Fe perturbed by the Ag in the K site is responsible for an enhancement of the linear absorption and photocurrent, as well as for the probable increase in the effective trap density. An enhanced trap density is likely the cause of the increased photorefractive counter-propagating two-beam coupling efficiency. http://www.scirj.org/jul-2014-paper.php?rp=P0714157

Bahan dan Panel Akustik Peredam Suara yang Bagus untuk Mengurangi Gema

Apabila merancang ruangan yang mana salah satu fungsi utama ruangan tersebut adalah mendengarkan suara, seperti studio rekaman, auditorium, gedung konser, home theater, ruang rapat, kelas sekolah dan sebagainya, kita harus memperhatikan aspek akustiknya. Apabila rancangan tersebut tidak memperhatikan aspek akustik, maka dapat dipastikan fungsi ruangan tersebut menjadi gagal. Beberapa kejadian akustik yang terjadi di sebuah ruangan adalah room modes, reflection (pantulan), absorbtion (penyerapan), diffusion (penyebaran), diffraction (pembayangan), dan lain-lain. Kejadian akustik tersebut terdengar oleh pendengar sebagai gema (echo), dengung (reverberation), bass boomy-flat, dan lain- lain. Banyaknya gema, panjangnya dengung, dan lain sebagainya apabila digabung, akan membentuk sebuah karakteristik akustik ruangan
