Background: The effects of vitamin D in skeletal system, biological metabolism and immune system function are well shown. Cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are two major types of vitamin D. Vitamin D deficiency is widely in human population and vitamin D intoxication is very rare. Case Description: The patient is 37-years old bodybuilder man who referred to emergency...

Recent literature establishes that ethnicity needs to be politically relevant to have a negative effect on a country’s development process. Yet, an understanding of the factors that cause ethnicity to be a political salient factor is still limited. This paper compares the development of the high politicization of ethnicity in Kenya to the low politicization in Tanzania by tracing the impact of ...

This paper proposes a new method for online secondary path modeling in feedback active noise control (ANC) systems. In practical cases, the secondary path is usually time-varying. For these cases, online modeling of secondary path is required to ensure convergence of the system. In literature the secondary path estimation is usually performed offline, prior to online modeling, where in the prop...

This paper reports on a study of geometry teaching at the lower secondary school level in Shanghai, China. Through an analysis of data from observing a variety of Year 9 (Grade 8) lessons, and utilising data from the students’ performance in school examinations, the study suggests that teachers in this region of China use classroom strategies that attempt to reinforce visual and deductive appro...

mild (140 to 159/90 to 99 mmhg) or moderate (160 to 179/100 to 109 mmhg) chronic arterial hypertension does not appear to cause headache. whether moderate hypertension predisposes patients to headache at all remains controversial, but there is little evidence that it does. ambulatory blood pressure monitoring in patients with mild and moderate hypertension has shown no convincing relationship b...

introduction use of hadron therapy as an advanced radiotherapy technique is increasing. in this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. in this study, monte carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. materials and methods i...
