PURPOSE To automatically segment multiple sclerosis (MS) lesions into three subtypes (i.e., enhancing lesions, T1 "black holes", T2 hyperintense lesions). MATERIALS AND METHODS Proton density-, T2- and contrast-enhanced T1-weighted brain images of 12 MR scans were pre-processed through intracranial cavity (IC) extraction, inhomogeneity correction and intensity normalization. Intensity-based s...

Groundwater and seepage samples were collected from both the natural and building-modified slopes in the highly urbanized spaces of the Mid-Levels area, Hong Kong. Groundwater in the natural slopes, although retaining some signatures from rainwater, is enriched in major cations such as Na, K, Ca and Mg and some anions such as HCO3 and SO4. Clearly, water-rock interactions, such as weathering of...

This study is aimed at assessing the physico-chemical parameters of water from Iwofe River which heavily stressed by extensive anthropogenic activities like bunkering. Two stations were established and surface samples collected bi-monthly each station for one year. All determined in-situ except biochemical oxygen demand (BOD) was analyzed in laboratory on fifth day sample collection. The result...

Teknologi budidaya sistem bioflok adalah ikan dengan padat tebar tinggi sedikit atau tanpa ganti air. Bioflok terdiri dari agregat mikro organisme dan bahan organik membutuhkan suplai oksigen, oleh karena itu jika volume terlalu perlu dikurangi mengganti sebagian air media. Tujuan penelitian mengetahui pengaruh pergantian terhadap kualitas performa pertumbuhan lele. Percobaan rancangan acak len...

In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

INTRODUCTION A slight decrease in blood testosterone level in men is a physiological state associated with the aging. The aim of our study was to evaluate the occurrence of hormone and metabolic disorders, as well as the immunolocalization and immunoexpression of androgen receptors (AR) and estrogen-alpha receptors (ERa) in the prostates of men with benign prostatic hyperplasia (BPH) and coexis...

The task scheduling problem in distributed memory machines is to allocate the tasks of an application into processors in order to minimize the total execution time. This is known as an NP-complete problem. Under the condition where the communication time is relatively shorter than the computation time for every task, the task duplication based scheduling (TDS) algorithm proposed by Darbha and A...

The role of calcium ions (Ca) in the generation of transient depolarizations (TDs) by acetylstrophanthidin was examined. Transmembrane activity was recorded from isolated canine false tendons exposed to acetylstrophanthidin; concentrations from 7.5 X 10"" to 2 X 10-" g/ml caused TDs coupled to driven action potentials and depressed slow diastolic depolarization. TDs could reach threshold and in...

Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical ...
