Aim: Hypospadias is a relatively common male genital anomaly that may be caused by anomalies in maternal hormone levels and/or blood glucose levels as well as nutritional deficiencies. Maternal obesity, which increases the risk of diabetes, may alter hormone levels, and may thereby be associated with risk of hypospadias. This study was designed to determine the impact of these risk factors on hypospadias in boys born at the largest tertiary hospital in Qatar. Methods: This population-based, case-control study used linked birth-hospital discharge data from Hamad General Hospital in Doha, Qatar, from January 2007 to December 2012. Boys with hypospadias were identified, and risk factors were determined. Adjusted odds ratios (aoRs) and 95% confidence intervals (CIs) for hypospadias were estimated by multivariable logistic regression models adjusted for maternal age, parity and body mass index (BMI). Results: Seventy-three newborn male infants with hypospadias and 100 without the condition, with birth weight above 2500 g, were compared. Maternal obesity (BMI ≥ 30 kg/m2) was not associated with risk of hypospadias (aoR 1.07;95% 0.95 - 1.21), and no trend in risk with increasing maternal BMI was observed. Conclusion: Although the causes of male genital malformation are multifactorial, the present data do not support the hypothesis that gestational maternal obesity is a cause of hypospadias in male infants.

The productive performance of giant freshwater prawn （Macrobrachium rosenbergii de Man） fed diet containing silkworm pupae （Bombyx mori） replacing for fish meal was conducted by focusing on digestibility, growth performance and feed utilization. Five diets of an isonitrogenous of 35 ：e 1% crude protein and isocaloric of digestible energy of 3,200 ±100 kcal/kg were formulated by using silkworm pupae, 0%, 8.6%, 17.2%, 25.8% and 34.7% by weight, replaced for fish meal. Giant freshwater prawn of 19 ± 2.0 g were stocked at 5 ind./m3 in concrete tank of 2.25 ton for three months. The protein digestibility by pepsin enzyme was evaluated in fish meal, silkworm pupae, soybean meal and shrimp meal. The digestibility was significantly difference （P 〈 0.05）. The protein digestibility of fishmeal and soybean meal was higher than silkworm pupae and shrimp meal. The productive performance of prawn in terms of growth rate and feed utilization were not significantly different （P 〉 0.05）. Therefore, silkworm pupae can be replaced for fishmeal in giant freshwater prawn （Macrobrachium rosenbergii de Man） without any adverse effects on productive performance.

This paper discusses a law enforcement officer (LEo) study that involved expert and novice police deputies from a small-sized city located in the Southern U.S. A virtual reality range was utilized to simulate high threat scenarios that require split second decisions on the use of deadly force. A fuzzy-logic based controller was constructed to analyze electroencephalogram (EEG) data collected from the participants. The fuzzy controller made use of several functions associated with the different regions of the brain to correlate Brodmann areas to multiple outputs. Electromagnetic Tomography (i.e. LoRETA) was used to identify where the signals from the surface electrodes originated within the brain through a process called source localization. once the sources of the EEG signals were located, they were associated with corresponding Brodmann areas. The fuzzy controller then provided insights on the subjects’ exhibited neural activation behavior indicative of vision, memory, shape/distance, hearing/sound, and theory of mind. Comparing and contrasting experienced and novice officers allowed for a greater understanding of the neurological processes present in police deputies when dealing with high threat situations.

Ditch cutting samples from Kasade-1 well were processed for microfauna, nannofossil and palynomorphs to throw more light on biostratigraphic events in the northern portion of the Bornu Basin, Nigeria. The lower section of the well within interval 990 - 1565 m yielded fairly abundant foraminifera species, while the upper section was barren. Palynomorph distribution follows the same pattern as observed for foraminifera except that few fresh-water algal species, Botryococcus braunii, were recovered from the upper section. The samples are devoid of nannofossil but contain few ostracod species, echinoid remains and fish tooth. Recognition of two planktonic foraminifera zones, Globotruncanella havanensis and Globotruncana aegyptiaca, enabled the delineation of the Campano-Maastrichtian and Maastrichtian boundary. The Cretaceous Tertiary boundary was inferred based on the top occurrence of palynomorph Dinogymnium euclaense. An abrupt truncation in the distribution of foraminifera species at a depth of about 990 m suggests unconformity, a widely reported event that followed the Santonian squeeze in the entire mega-Chad Basin.

A novel bisphosphine ligated Ag60 nanocluster,[{Cl@Ag12}@Ag48(dppm)12], has been dis-covered and characterized by X-ray crystallography. It consists of a central chloride located inside an icosahedral silver core layer, which is further encased by a second shell of 48 silver atoms/ions, which are capped with 12 bis(diphenylphosphino)methane (dppm) ligands. Due to lack of sufficient material the cluster could not be further characterized by other methods. DFT calculations were carried out on the cation [{Cl@Ag12}@Ag48(dppm)12]+ to determine if it corresponds to a superatom with a core count of n=58. The DFT optimized structure is in agreement with X-ray ndings, but the low value of the HoMo-LUMo gap does not support superatom stability.

Aim: To assess the lifetime prevalence of tension-type headache, migraine and chronic daily headache, including the primary headaches in a student population. Methods: This is a cross-sectional descriptive study. Data were collected from consecutive consenting students by means of a semi-structured questionnaire. The questionnaire was designed to assess demographic data, headache profiles and medical consultation. Results: Four hundred and forty-nine (89.8%) out of 500 students who were interviewed were analyzed. The lifetime prevalence of primary headache was 89.8%;it 90.5% and 88.6% in females and males respectively. The overall prevalence of migraine was 8.9%, with a prevalence of 10.6% in females and 6.5% in males. Migraine without aura was most commonly seen at 73%. The prevalence of migraine without aura was 7.6% in females and 4.9% in males. Tension type headache (TTH) had an overall prevalence of 22.9%, with a prevalence of 28.4% in females and 15.1% in males. Migraine and tension type headache co-existed in 5.8% of the students. About 8.5% suffered from chronic daily headache: chronic migraine 2.9%, chronic tension headache 3.1%. The rate of medical consultation was 54.8% (males 49.7%, females 58.3%). Conclusions: Headache is a common health problem among medical and nursing students in Enugu South East Nigeria where 89.8% of respondents have had primary headaches. The prevalence of migraine, TTH and chronic daily headache was 8.9%, 22.9% and 8.5% respectively. Headaches therefore, represent one of the most challenging neurological disorders in Sub-Saharan Africa where most sufferers do not have access to specialist care.
