Authors: Su Jun feng , Lian Ting ting , Huang Ting lin , Liang Dong hui , Wang Wen dong 
Published: November 2017

Abstract
In this study, strain CC76, identified as Enterobacter sp., was tested for the reduction of Fe3+ and denitrification using immobilized pellets with strain CC76 as experimental group (IP) and immobilized pellets with strain CC76 and magnetite powder as experimental group (IPM) in the autotrophic denitrification immobilized systems (ADIS). Compared with IP, a higher nitrate removal rate was obtained with IPM by using three levels of influent Fe3+ (0, 5, and 10 mg/L), four levels of pH (5.0, 6.0, 7.0, and 8.0), and three levels of hydraulic retention time (HRT) (12, 14, and 16 h), respectively. Furthermore, response surface methodology (RSM) analysis demonstrated that the optimum removal ratios of nitrate of 87.21% (IP) and 96.27% (IPM) were observed under the following conditions: HRT of 12 h, pH of 7.0 and influent Fe3+ concentration of 5 mg/L (IP) and 1 mg/L (IPM).

Abstract
The aim of this study is to create a hydraulic numerical model to analyze the hydraulic transient process associated with the water delivery system of the cascade pumping stations of the Miyun Reservoir Regulation and Storage Project. Based on the characteristics of the project, which include open channels, co-dependent structures and control structures, a mathematical model of the corresponding inner boundary was established. The numerical model of transient flow was developed by combining computer simulation techniques with the one-dimensional Saint-Venant equations. This approach is suitable for the water delivery system of cascade pumping stations. This model was subsequently applied in the study area. The numerical simulation results show that the model of the hydraulic transient process yielded relatively high precision (error of less than 2 cm). The model was used to perform numerical simulations of flow regulation and emergency conditions in the water conveyance system. The study provides a practical numerical method for precisely evaluating the hydraulic transient process for the water delivery system of cascade pumping stations, basic data for the operation and optimization of the water conveyance system, and a reference for the safe operation of the Miyun Reservoir Storage Project, as well as efficient water delivery.

Authors: Guo Jiankang , Zhang Yanting , Che Shengquan 
Published: November 2017

Abstract
Current research has validated the purification of rainwater by a substrate layer of green roofs to some extent, though the effects of the substrate layer on rainwater purification have not been adequately quantified. The present study set up nine extensive green roof experiment combinations based on the current conditions of precipitation characteristics observed in Shanghai, China. Different rain with pollutants were simulated, and the orthogonal design L9 (33) test was conducted to measure purification performance. The purification influences of the extensive green roof substrate layer were quantitatively analyzed in Shanghai to optimize the thickness, proportion of substrate, and sodium polyacrylate content. The experimental outcomes resulted in ammonium nitrogen (NH4+-N), lead (Pb), and zinc (Zn) removal of up to 93.87%, 98.81%, and 94.55% in the artificial rainfall, respectively, and NH4+-N, Pb, and Zn event mean concentration (EMC) was depressed to 0.263 mg/L, 0.002 mg/L and 0.018 mg/L, respectively, which were all well below the pollutant concentrations of artificial rainfall. With reference to the rainfall chemical characteristics of Shanghai, a combination of a 200 mm thickness, proportions of 1:1:2 of Loam: Perlite: Cocopeat and 2 g/L sodium polyacrylate content was suggested for the design of an extensive green roof substrate to purify NH4+-N, Pb and Zn.
Oxygen Transfer in Moving Bed Biofilm Reactor and Integrated Fixed Film Activated Sludge Processes
Authors: Daigger Glen T. , Boltz Joshua P. 
Published: November 2017

ABSTRACT: A demonstrated approach to design the, so‐called, medium‐bubble air diffusion oxygen transfer system for moving bed biofilm reactor (MBBR) and integrated fixed film activated sludge (IFAS) processes is described. Operational full‐scale biological water resource recovery systems treating municipal sewage, designed using this methodology, provide reliable service. Further improvement is possible, however, as knowledge gaps are filled and results in more rationally‐based system designs. Pilot‐scale testing demonstrates significant enhancement of oxygen transfer capacity from the presence of media. Establishment of the relationship in full‐scale systems between diffuser submergence, aeration rate, and biofilm carrier fill fraction will enhance MBBR and IFAS aerobic process design, cost, and performance. Limited testing of full‐scale systems prevents computation of alpha values and can be addressed by further full‐scale testing under actual operating conditions. Control of MBBR and IFAS aerobic zone oxygen transfer systems can be optimized by recognizing that varying residual dissolved oxygen concentrations are needed, depending on operating conditions. Further application of oxygen transfer control approaches used in activated sludge systems, such as ammonia‐based oxygen transfer system control, further improves MBBR and IFAS system energy efficiency.

This qualitative research focuses on school administrators’ experiences with transgender students’ identity expression as it relates to school policies and student body experiences of transgender inclusion. Implications for district and building policy are also discussed.
Ectopic Pregnancy Following Interval Tubal Sterilization
Authors: Shrestha Deepak , Baniya Sebina , Regmi Sudeep 
Published: November 2017

Introduction: Tubal sterilization is a highly effective method of permanent contraception. However, pregnancy can still occur following a successful procedure. Published literatures report a failure rate of 0.13-1.3% and 15-33% of such pregnancies are likely to be ectopic.
Case report: A 33 years para three lady with prior history of tubal ligation presented with generalized abdominal pain and several episodes of vomiting. Bimanual examination revealed a soft and mobile mass of 2 x 3 cm in right adnexa. Urine pregnancy test was positive and ultrasonogram showed a heterogeneous mass of 3.4 x 3.3 cm in right adnexa with empty uterine cavity. Culdocentesis resulted in aspiration of frank non-clotting blood. She then underwent emergency laparotomy with bilateral salpingectomy for ruptured ectopic pregnancy.
Conclusion: Ectopic pregnancy after tubal sterilization though rare is not entirely impossible. All women who are offered this procedure should always be educated about its failure rate. And in women presenting with acute abdomen, a prior history of tubal sterilization doesn't preclude the possibility of ectopic pregnancy.

Authors: Puckrein Gary A. , Hirsch Irl B. , Parkin Christopher G. , Taylor Bruce T. , Xu Liou , Marrero David G. 
Published: November 2017

OBJECTIVE
Use of glucose monitoring is essential to the safety of individuals with insulin-treated diabetes. In 2011, the Centers for Medicare & Medicaid Services (CMS) implemented the Medicare Competitive Bidding Program (CBP) in nine test markets. This resulted in a substantial disruption of beneficiary access to self-monitoring of blood glucose (SMBG) supplies and significant increases in the percentage of beneficiaries with either reduced or no acquisition of supplies. These reductions were significantly associated with increased mortality, hospitalizations, and costs. The CBP was implemented nationally in July 2013. We evaluated the impact of this rollout to determine if the adverse outcomes seen in 2011 persisted.

RESEARCH DESIGN AND METHODS
This longitudinal study followed 529,627 insulin-treated beneficiaries from 2009 through 2013 to assess changes in beneficiary acquisition of testing supplies in the initial nine test markets (TEST, n = 43,939) and beneficiaries not affected by the 2011 rollout (NONTEST, n = 485,688). All Medicare beneficiary records for analysis were obtained from CMS.

RESULTS
The percentages of beneficiaries with partial/no SMBG acquisition were significantly higher in both the TEST (37.4%) and NONTEST (37.6%) groups after the first 6 months of the national CBP rollout, showing increases of 48.1% and 60.0%, respectively (both P &lt; 0.0001). The percentage of beneficiaries with no record for SMBG acquisition increased from 54.1% in January 2013 to 62.5% by December 2013.

CONCLUSIONS
Disruption of beneficiary access to their prescribed SMBG supplies has persisted and worsened. Diabetes testing supplies should be excluded from the CBP until transparent, science-based methodologies for safety monitoring are adopted and implemented.
Declining Rates of Hospitalization for Selected Cardiovascular Disease Conditions Among Adults Aged ≥35 Years With Diagnosed Diabetes, U.S., 1998–2014
Authors: Burrows Nilka Ríos , Li YanFeng , Gregg Edward W. , Geiss Linda S. 
Published: November 2017

OBJECTIVE
Reductions in heart attack and stroke hospitalizations are well documented in the U.S. population with diabetes. We extended trend analyses to other cardiovascular disease (CVD) conditions, including stroke by type, and used four additional years of data.

RESEARCH DESIGN AND METHODS
Using 1998–2014 National (Nationwide) Inpatient Sample (NIS) data, we estimated the number of discharges having acute coronary syndrome (ACS) (ICD-9 codes 410–411), cardiac dysrhythmia (427), heart failure (428), hemorrhagic stroke (430–432), or ischemic stroke (433.x1, 434, and 436) as first-listed diagnosis and diabetes (250) as secondary diagnosis. Hospitalization rates for adults aged ≥35 years were calculated using estimates from the population with and the population without diabetes from the National Health Interview Survey (NHIS) and age-adjusted to the 2000 U.S. standard population. Joinpoint regression was used to analyze trends and calculate an average annual percentage change (AAPC) with 95% confidence limits (CLs).

RESULTS
From 1998 to 2014, in the population with diabetes, age-adjusted hospitalization rates declined significantly for ACS (AAPC −4.6% per year [95% CL −5.3, −3.8]), cardiac dysrhythmia (−0.7% [−1.1, −0.2]), heart failure (−3.6% [−4.6, −2.7]), hemorrhagic stroke (−1.1% [−1.4, −0.7]), and ischemic stroke (−2.9% [−3.9, −1.8]). In the population without diabetes, rates also declined significantly for these conditions, with the exception of dysrhythmia. By 2014, rates in the population with diabetes population remained two to four times as high as those for the population without diabetes, with the largest difference in heart failure rates.

CONCLUSIONS
CVD hospitalization rates declined significantly in both the population with diabetes and the population without diabetes. This may be due to several factors, including new or more aggressive treatments and reductions in CVD risk factors and CVD incidence.
Hematological and biochemical changes in rabbits exposed to castor oil (Ricinus communis) under experimental conditions
Authors: Ahmed Sahar M. 
Published: November 2017

In the last few decades there has been an exponential growth in the field of herbal medicine. One
such medicinal plant is Ricinus communis (Euphorbiaceae), which is commonly known as castor.
All parts of the plant are important phloem, bark, leaves, flowers, seed and oil. The study was
conducted on 15 mature rabbitsof either sex of 1-2 kg body weight and 1-2 years old. The animals
were divided into three groups of 5 animals each. Animals of group I were exposed orally to ricin
extract at a dose rate of 0.5 mg /kg b.wt. daily for 14 days, while those of group II were exposed
orally to aqueous leaves extract 0.5mg /kg b.wt daily for 14 day, mean while those of group III
were left as a control group not exposed. The dependent parameters in the study were hemoglobin
(Hb) concentration, total erythrocytes count, packed cells volume (PCV%), erythrocytes indices
mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular
hemoglobin concentration (MCHC), Total and differential leucocytes count (TLC and DLC), in
addition to some biochemical tests of blood serum which obtained at day 14th post exposure. The
results of the study were revealed that the ricin extract and leaf extract exhibited an effects on
hematological pictures as the erythrocytes counts, erythrocytes indices, Hb concentration and
PCV% decreased and the obvious effects were in the 14th day. Ricin extract was less effects on
many dependent parameters in comparison with aqueous leaf extract. Total leucocytes count,
neutrophils % was increased in both ricin and leaf extract, and the increasing were higher in the
7th day in Ricin extract group. The lymphocytes% was decreased. While monocytes, eosinophils, and basophils % did not show any significant changes in all groups. Neutrophil /lymphocyte (N/l), and monocyte /lymphocyte (M/l) increased in both exposed groups. Cholesterol (Chol), Triglyceride (TG)were increased, while total protein (TP)was decreased, Albumin (Alb), Cortisol (Cort), Total serum bilirubin (TSB) and Alanine aminotransferase (ALT)did not changed. Aspartate aminotransferase (AST) value was increased, while Adenosine phosphatase (AP) value was deceased. In conclusion castor oil due to its content of ricin exhibit an effects on hematological and biochemical parameters that depended in the study, and the leaves extract was higher than seed extract in its effects.

Authors: Al-Ubadi Alia E. 
Published: November 2017

Association between Procalcitonin (PCT) and C-reactive protein (CRP) and burn injury was evaluated in 80 burned patients from Al-Kindy and Imam Ali hospitals in Baghdad-Iraq. Patients were divided into two groups, survivor group 56 (70%) and non-survivor group 24 (30%). PCT was estimated using (Human Procalcitonin ELISA kit) provided by RayBio/USA while CRP was performed using a latex agglutination kit from Chromatest (Spain).
Our results declared that the mean of Total Body Surface Area (TBSA %) affected were 63.5% range (36%–95%) in non-survivor patients, while 26.5% range (10%–70%) in survivor patients. There is a significant difference between the two groups (P = 0.00), the higher mean percentage of TBSA has a significant association with mortality.
Serum PCT and CRP were measured at the three times of sampling (within the first 48hr following admission, after 5thdays and after 10th days). The mean of PCT serum concentrations in non-survivor group (2638 ± 3013pg/ml) were higher than that of survivor group (588 ± 364pg/ml). Significantly high levels of CRP were found between the survivor and non-survivor groups especially in the 10th day of admission P=0.000, present study show that significant differences is found within the non-survivor group through the three times P= 0.01, while results were near to significant differences within survivor group through the three times (P= 0.05).

Authors: Saeed Noor Al-Huda A. 
Published: November 2017

Cyclical angiogenesis in the ovary is a unique process supporting normal folliculogenesis as well as lute genesis. In this report we investigated the reactivity of rabbit anti pseudomonas aeruginosa antisera with ovarian blood vessels.
Tissues stained with anti-sera were immunohistochemically visualized using biotinylated anti rabbit immunoglobulin and peroxidase conjugated streptavidin. Positive staining sites depend on anti-stain type, however, staining was observed in endothelial cell and tunica adventitia in most cases.On the other hand, corpus luteum blood vessels showed a positive staining pattern as well.
We conclude from this study that a peculiar staining pattern was seen in ovarian blood vessels stained with rabbit anti-pseudomonas aeruginosa hyper immune sera, the importance of this reactivity need further investigation.

It was calculated the average concentrations of elements manganese, iron, cobalt, nickel, copper, zinc, arsenic, cadmium and lead in the sixteen samples of drinking water (tap water), were collected from different areas in the Baghdad city. The Results indicated that the average of concentrations of the elements Mn, Fe, Pb, Ni and Cd (0.44ppm, 0.49ppm, 0.04ppm, 0.17ppm and 1.2ppm respectively) higher than permissible limit while the concentrations of elements Cu and Zn (0.11ppm and 0.14ppm respectively) were lower than the permissible limit of World Health Organization (WHO) standards (1ppm and 3ppm) respectively for drinking water and the concentration of Arsenic in the nuclear lab sample in college of sciences - Mustansiriyah University was higher than permissible limit.
All the drinking water samples were analyzed and determined the physical and chemical properties such as Electrical Conductivity (EC), pH, and Total Dissolved Solids (TDS). The highest value was (1064μS/cm) in Al-Tuwaitha sample and the lowest value (531μS/cm) in Al-Sadr City (Sector 7) sample for the Electrical Conductivity. The pH values ranged from (7.0-8.2). The average levels of Total Dissolved Solids (TDS), the highest value was 550 mg/L in the Diyala Bridge sample while the lowest value 276mg/L in Al-Sadr City (Sector 7) sample. The results were compared with national and international standards, and it’s also showed that the values of the parameters within the permissible limit of World Health Organization (WHO) standards, except the Electrical Conductivity values for some samples were higher than permissible limit. According to these results, all the water projects must be monitored as well as using the proper and modern techniques for treatment the drinking water.
Análises cerâmicas na arqueologia amazônica
Authors: Lima Helena Pinto 
Published: November 2017

Classificação das cerâmicas arqueológicas foi tema bastante debatido entre arqueólogos que trabalharam na Amazônia nas décadas de 1950-70 e evidenciou divergências entre as hipóteses de ocupação da região. As diferentes interpretações dadas a este vestígio partiam de parâmetros classificatórios distintos. Este artigo apresenta as discussões sobre métodos de tratamento da cerâmica arqueológica na Amazônia, contextualizando as abordagens histórica e teoricamente. Num segundo momento expõe a metodologia de análise cerâmica utilizada para interpretar as sequências crono-estratigráficas dos contextos arqueológicos da Amazônia central e adjacências. Para tal, lança mão da análise e tipologia produzidas para o sítio arqueológico Jacuruxi, município de Manacapuru/AM, que desafiam os parâmetros interpretativos adotados e apontam para a necessidade de uma abordagem contextual abrangente.
