Design Consideration of Electrical Earthing System for High-rise Building

Electricity is dangerous and required proper grounding to prevent unwanted voltage from passing through personnel, critical equipment and other nearby metallic objects. Soil resistivity directly affects the design of a grounding system. When designing an extensive grounding system it is advisable to locate the area of lowest soil resistivity in order to achieve the economical grounding installation. Neither very low resistivity nor very high resistivity is safe for human safety under power system fault conditions. The earthing or grounding is mainly affected by soil resistivity. This study will briefly explain the earthing of Lightning Protection System for 11th storeyed building. The soil type of this building is loam and soil resitivity is 150 Ωm

Biowarfare and Rheumatology

A 23 years old single policeman was presented to emergency department of Yangon General Hospital on 8.1.2020 with the chief complaint of puffiness of face followed by bilateral leg swelling accompanied by reduced urine output for 10 days. Preceding history of low grade intermittent fever with dry cough was noted 3 months ago. He had sharpstabbing anterior chest pain but did not notice palpitation, orthopnoea or paroxysmal nocturnal dyspne

Automatic Myanmar Text Summarization System

Automatic text summarization is used as atool to help people in reducing the time spentmanually extracting the main ideas from textdocuments. If the natural disaster news isprovided as the summary form includingimportant and relevant information, people inmanagement level can make comparisons andintelligent decisions quickly without exhaustingenergy by manually extracting the salient points.Moreover, for a normal user, automaticsummary report of the disaster news makes themclear perception and fully awareness of theeffects of the natural disaster by inspecting deathtoll and damage of the natural hazards.Therefore, this paper proposes AutomaticMyanmar Text Summarization framework that isbased on Information Extraction and practicalimplementation of this framework insummarizing natural disaster news which are inseven types: Earthquake, Flood, Landslide,Forest Fire, Tornado, Storm and VolcanicEruption described in Myanmar Language. Thetwo main components of the proposedframework, Myanmar Word Segmentation modelbased on Conditional Random Fields (CRFs)and Information Extraction Model using CRFs approach are also introduced

Assessment of Dyeing Properties of Natural Dye Extracted from the Fruit of Myrobalan (Phan-Kha)

In this study, natural colorant extracted from the fruit of Myrobalan (Phan-kha) was applied on cotton fabric using alum, copper sulphate and potassium dichromate as mordant. The effects of mordant, dyeing time and dyeing temperature on the color strength of dyed cotton fabrics were measured. The fastness properties of dyed cotton fabrics such as washing fastness, rubbing fastness and light fastness were also evaluated. It was found that using the metal mordants increased the color strength of the dyed cotton fabrics. It was shown that all mordants increased in rubbing fastness and washing fastness of dyed cotton fabrics, but the light fastness increased in the used of copper sulphate and potassium dichromate mordants

Corticosteroid-induced Osteoprorsis: 10-year Fracture Risk in Systemic Lupus Erythematosis

Osteoporosis is of special interest since the last few decades due to its increased fracture risk resulting in increased mortality and morbidity in elderly populations, especially in women
