Experiment and Simulation Effects of Cyclic Pitch Control on Performance of Horizontal Axis Wind Turbine
Authors: Sang Le Quang , Maeda Takao , Kamada Yasunari , Li Qing'an 
Published: June 2017

Offshore wind is generally stronger and more consistent than wind on land. A large part of the offshore wind resource is however located in deep water, where floating wind turbines can harvest more energy. This paper describes a systematic experiment and a simulation analysis (FAST code) about the cyclic pitch control of blades. This work was performed to investigate performance fluctuation of a floating wind turbine utilizing cyclic pitch control. The experiment was carried out in an open wind tunnel with mainstream wind velocity of 10 m/s with the front inflow wind and the oblique inflow wind conditions. A model wind turbine is two-bladed downwind wind turbine with diameter of 1.6 m. Moment and force acts on the model wind turbine were measured by a six-component balance. Fluctuation of power coefficient and thrust coefficient was investigated in the cyclic pitch control. The model wind turbine and the experimental conditions were simulated by FAST code. The comparison of the experimental data and the simulation results of FAST code show that the power coefficient and thrust coefficient are in good agreement.

AbstractReplacement of canonical histones with specialized histone variants promotes altering of chromatin structure and function. The essential histone variant H2A.Z affects various DNA‐based processes via poorly understood mechanisms. Here, we determine the comprehensive interactome of H2A.Z and identify PWWP2A as a novel H2A.Z‐nucleosome binder. PWWP2A is a functionally uncharacterized, vertebrate‐specific protein that binds very tightly to chromatin through a concerted multivalent binding mode. Two internal protein regions mediate H2A.Z‐specificity and nucleosome interaction, whereas the PWWP domain exhibits direct DNA binding. Genome‐wide mapping reveals that PWWP2A binds selectively to H2A.Z‐containing nucleosomes with strong preference for promoters of highly transcribed genes. In human cells, its depletion affects gene expression and impairs proliferation via a mitotic delay. While PWWP2A does not influence H2A.Z occupancy, the C‐terminal tail of H2A.Z is one important mediator to recruit PWWP2A to chromatin. Knockdown of PWWP2A in Xenopus results in severe cranial facial defects, arising from neural crest cell differentiation and migration problems. Thus, PWWP2A is a novel H2A.Z‐specific multivalent chromatin binder providing a surprising link between H2A.Z, chromosome segregation, and organ development.

Heritage Lost:The cultural impact of wildlife crime in South Africa
Authors: Griffiths Megan Laura 
Published: June 2017

Crimes against wildlife have come to the fore in South Africa in the past decade – largely due to the dramatic escalation of rhino poaching. As a major custodian of iconic species such as the Big Five, South Africa is at the core of the illicit wildlife economy. Since the country is reliant on wildlife tourism for economic development, poaching brings serious financial consequences. These negative impacts, however, extend far beyond the economy and also protrude into the cultural sphere. While some South Africans may be unmoved by the plight of the country’s wildlife as a result of a lack of exposure thereto, many feel socially linked to wildlife. Concerned citizens often consider that future generations will not be able to experience wildlife due to extinction, and will thus be deprived of their rightful cultural inheritance. The impact of wildlife crime may therefore be seen as a form of cultural victimisation.
Can Co-enzyme Q10 improve the chances of conception after the age of 35?
Authors: Abd El Fattah Eman Ali 
Published: June 2017

Background: ovarian follicular quality diminishes with age, Free radicals and oxidative stress begin to accumulate in cells, aging or slowing down the metabolic energy production centers in the cell- the mitochondria. When the mitochondria cannot generate a certain amount of energy, it slows growth and proper development of the follicle making it more prone to DNA damage, including chromosomal abnormalities resulting in poor fertilization patterns, and early miscarriage. Co-enzyme Q10 (CoQ10) is a major cellular antioxidant. its tissue levels gradually decrease with age. We attempt to evaluate its protective effect on ROS-induced ovarian damage, which is one of the most important and widely accepted patho- mechanisms underlying cell ageing.Methods: 40 Participants from El Shatby hospital infertility clinic 35 to 38 years old, with history of bad response to ovulation stimulation, were divided into two equal groups (group A given (CoQ10) 3mg|kg body weight for three cycles prior to stimulation Serum anti- mullarian hormone level was measured before and after CoQ10 administration, group B= twenty cases as control). Participants were given gonadotrophins (150 IU to 375 IU). Follicular growth was monitored by trans- vaginal ultra- sonography and serum estradiol level (E2). Ovulation trigger was achieved using 10,000 IU of human chorionic gonadotrophin.Results: The primary outcome was occurrence of normal pregnancy; secondary outcome was good response to stimulation (at least one mature follicle 18-22mm).Conclusions: CoQ10 has no significant effect on response to ovulation stimulation or on pregnancy rates.

Published: June 2017

Background: Knowledge of fetal weight in utero is vital for the obstetrician in deciding whether to deliver the fetus as well as in fixing the mode of delivery. Both low birth weight and excessive fetal weight at delivery are associated with increased risk of newborn complications during labor and the puerperium. During the last decade, estimated fetal weight has been incorporated into the standard routine antepartum evaluation of high-risk pregnancies and deliveries. Objective of present study was to assess the fetal weight in term pregnancies by Clinical and Sonographic and to compare the methods after knowing the actual weight of the baby after birth.Methods: It is a prospective and comparative study of 200 women at term pregnancy at Sir T. Hospital, Bhavnagar, India from 2015 to 2016. Patients within 7 days from their Expected Date of Delivery were included in the study. The formulas used in this study are: Johnson's formula, Dare’s formula and Hadlock's formula using ultrasound.Results: Results vary in terms of accuracy with various methods employed for estimating the fetal weight. This study showed that Dare’s Formula was the best indicator among all other methods assessed followed by Hadlock's formula by ultrasonographic method.Conclusions: SFH measurement continues to be used in many countries on large scale because of its low cost, ease of use and need for little training as the setup for ultrasonographic evaluation is not readily available in rural setups.
Caesarean delivery on maternal request (CDMR): clinical and ethical dilemma
Authors: Mann Ankita , Mehta Sumita , Grover Anshul 
Published: June 2017

Now a days, in developing countries like India, one of the most common contributing factor for increasing caesarean section rate is CDMR (Caesarean delivery on maternal request). Incidence of CDMR reached upto 18 percent of total caesarean deliveries worldwide. The issue of CDMR is ongoing bioethical debate which highlights the struggle to balance patient autonomy with duty of obstetrician to uphold the principle of beneficence, non maleficence and justice. Our mission should be to promote safe, effective and satisfying maternity care for all women and their families through research, education, expertise and advocacy.
