RESUMO: A importância do milho (Zea mays) não está apenas na produção de uma cultura anual, mas em todo o relacionamento que essa cultura tem na produção agropecuária brasileira, tanto no que diz respeito a fatores econômicos quanto a fatores sociais. Todos os aspectos de crescimento e desenvolvimento das plantas podem ser afetados pela deficiência hídrica e saturação de água nos tecidos, causada pela excessiva demanda evaporativa e/ou limitado suprimento de água. O objetivo desse trabalho foi avaliar os efeitos do alagamento sob conteúdo relativo de água, nº de folhas, massa seca do colmo, massa seca da raiz e massa seca das folhas em plantas de milho submetidas ao alagamento. O experimento foi conduzido em casa de vegetação da Universidade Federal Rural da Amazônia (UFRA - Capitão - Poço), utilizando-se plantas de milho variedade BR 5102, o delineamento experimental foi inteiramente casualizado (DIC) com fatorial 2 x 4, com duas condições hídricas: controle, déficit hídrico e quatro ciclos de estresse com 5 cinco repetições. Obtiveram-se resultados significativos em todos os parâmetros avaliados, concluindo que o alagamento influenciou negativamente na biometria das plantas. PALAVRAS-CHAVE: anoxia, produtividade, raiz.

Performance Analysis of Cellular Radio System Using Artificial Neural Networks
Authors: Gupta Kriti Priya 
Published: June 2016

In this paper, we exploit one of the fastest growing techniques of Soft Computing, i.e. Artificial Neural Networks (ANNs) for obtaining various performance measures of a cellular radio system. A prioritized channel scheme with subrating is considered in which a fixed number of channels are reserved for handoff calls and in case of heavy traffic, these reserved channels are subrated into two channels of equal frequency to deal with more handoff calls. Two models dealing with infinite and finite number of subscribers are considered and the blocking probabilities of new and handoff calls are computed analytically as well as by using ANNs. A feedforward two-layer ANN is considered for obtaining the blocking probabilities. The backpropagation algorithm is used for training the ANN. The analytical and ANN results are compared by taking the numerical illustrations.

Hence, fungicides can be applied occasionally on these soils to reduce the fungi load in these areas when necessary.Data obtained in this study is valuable to monitor and protect the environment including agriculture products for sustainable economic development.
Resistance pattern of enterococcus for high level aminoglycosides and vancomycin in blood culture of admitted patients
Authors: Yaqoob Shadma 
Published: June 2016

Enterococci have emerged as important nosocomial pathogens from a variety of clinical conditions and the major reason for this is the trend of increasing antimicrobial resistance and enterococcal bacteraemia results in a high mortality. The present study was undertaken to determine the occurrence, species prevalence, antibacterial resistance, with a special reference to vancomycin and high level aminoglycoside resistance. Material and methods: The study was conducted on blood culture isolates. The antibiotic susceptibility of isolates by the Kirby Bauer disc diffusion method was done according to the CLSI guidelines. Screening tests for high level aminoglycosides and vancomycin and minimum inhibitory concentration (MIC) tests for vancomycin was done. The blood specimens were cultured and suspected growths were identified to species level and found to consist mostly of E. fecalis (70%). VRE accounted for 2 (91%) isolates and high level aminoglycoside resistance was seen in 47.82 and 60.86 isolates. The E. faecium isolates were more drug resistant than the E. faecalis isolates. Linezolid and Teicoplanin showed good anti-enterococcal activity. This study shows an emergence of Vancomycin resistant enterococcus (VRE) along with increased rate of multidrug-resistant enterococci. Regular surveillance of antimicrobial susceptibilities and treatment of enterococcal infections should be done effectively to limit the spread of multidrug resistance.

Dumping of industrial wastes into the sea is a common factor in and near by coastal cities where by there are mass mortalities of fishes as well as health deterioration of fish health. These fishes are prone to secondary infections by microbial and eukaryotic parasitic species. In the present study a survey has been made on Johnius aneus for copepod parasites infection. The study has been conducted+ for 10 months. 3 species of parasites were recorded-Lernanthropus Otolith, Pillai, 1963 Caligus annualaris Yamaguti, 1954 and Brachiella albida Ranganekar, 1956. To know the host parasite interaction, prevalence and Mean Intensity of overall parasites and individual parasite species have been studied. It is found that over all prevalence is high being 44%, whereas Mean intensity is less being 1.6. This gives an overall view of parasitization of copepods on the fish Johnius. It indicates that infection with copepod parasites is common but not heavy.

Published: June 2016

Prunus cerasoides D. Don the Himalayan wild cherry is one lesser known multipurpose tree species of Himalaya. The tree prefers to grow on sloping grounds between the altitudes of 1200-2400 m, on all types of soils and rocks. The tree is used as a medicinal plant in Himalayan region. The fruit is edible and the pulp is used to make a cherry brandy. The species has poor germination and seedling establishment in natural habitat. The over exploitation of seeds of the species coupled with relatively hard seed coat has adversely affects the germination of seeds in their natural habitat. The information about the seed maturity and technique of germination enhancement is scanty. The present study was conducted to assess the exact maturity time and optimum temperature for enhancement of germination in seed of P. cerasoides. The fruit/seeds were collected from six sites covering the altitudinal range of 1350 – 1810 m during the period (2003-2004). The colour change of fruit from dark green to red was a useful indicator of seed maturity. Maximum germination coincided with 50.24 ± 0.19 % fruit and 30.11 ± 0.57 % seed moisture content. Negative correlation existed between germination and seed moisture content (r = 0.294; P< 0.01). Significantly higher germination occurred when seeds were placed above the paper at 25º C.

Published: June 2016

Background and objectives
Awareness of CKD is necessary for patient engagement and adherence to medical regimens. Having an accurate tool to assess awareness is important. Use of the National Health and Nutrition Examination Survey (NHANES) CKD awareness question “Have you ever been told by a doctor or other health professional that you had weak or failing kidneys (excluding kidney stones, bladder infections, or incontinence)?” produces surprisingly low measures of CKD awareness. We sought to compare the sensitivity and specificity of different questions ascertaining awareness of CKD and other health conditions.

Design, setting, participants, & measurements
Between August of 2011 and August of 2014, an in-person questionnaire was administered to 220 adults with CKD, diabetes, hypertension, or hyperlipidemia who received primary care in a public health care delivery system to ascertain awareness of each condition. CKD awareness was measured using the NHANES question, and other questions, asking if patients knew about their “kidney disease”, “protein in the urine”, “kidney problem”, or “kidney damage.” Demographic data were self-reported; health literacy was measured. The sensitivity and specificity of each question was calculated using the medical record as the gold standard.

Results
In this diverse population (9.6% white, 40.6% black, 36.5% Hispanic, 12.3% Asian), the mean age was 58 years, 30% had a non-English language preference, and 45% had low health literacy. Eighty percent of participants had CKD, with a mean eGFR of 47.2 ml/min per 1.73 m2. The sensitivities of each CKD awareness question were: 26.4% for “kidney damage”, 27.7% for “kidney disease”, 33.2% for “weak or failing kidneys”, 39.8% for “protein in the urine”, and 40.1% for “kidney problem.” Specificities ranged from 82.2% to 97.6%. The best two-question combination yielded a sensitivity of 53.1% and a specificity of 83.3%. This was lower than awareness of hypertension (90.1%) or diabetes (91.8%).

Conclusions
CKD awareness is low compared with other chronic diseases regardless of how it is ascertained. Nevertheless, more sensitive questions to ascertain CKD awareness suggest current under-ascertainment.
Comparative Effects of mEOC on the Structures and Properties of PP/SGF and PP/EOC/SGF Composite Foams
Authors: Yang J.-N. 
Published: June 2016

Abstract
To improve the impact toughness of short glass fiber (SGF) reinforced polypropylene (PP) composite foams, maleic anhydride grafted ethylene-α-octene copolymer (mEOC) was employed as impact modifier and interfacial compatibilizer. And for comparison, mEOC was also introduced into PP/EOC/SGF composite foams. Then, the foaming qualities, interfacial structures and mechanical properties of samples against varying mEOC contents were examined and compared in detail. Results showed that adequate mEOC significantly improved the foamabilities of the composites, while the optimized mass fraction was 8% for PP/SGF composite foams and 3% for PP/EOC/SGF system. Increased mEOC facilitated the higher impact toughness, which was increased by 77% for PP/SGF composite foams, whereas only 5% for PP/EOC/SGF foams. However, the flexural strengths were just improved slightly, while compressive strengths decreased monotonically with mEOC for the investigated composite foams.

Published: June 2016

Abstract
Styrenic copolymers comprising styrene, methyl methacrylate, and maleic anhydride were developed to improve the heat-resistance property of poly(methyl methacrylate) (PMMA). The optical, thermal, and mechanical properties were examined for the blend specimens prepared by an injection-molding machine using melt-mixed samples. It was found that the copolymers, which were miscible with PMMA, increase the glass transition temperature and therefore the Vicat Softening temperature. Furthermore, the blends were completely transparent as similar to PMMA.

Published: June 2016

Abstract
This study investigates the abrasive water jet turning (AWJT) process of commonly used plastics, such as polytetrafluoroethylene (PTFE), castamide, and polyamide (PA), in engineering. Machining parameters were used as follows: nozzle feed rate (10, 30, and 50 mm min−1), abrasive flow rate (50, 250, and 450 g min−1), and spindle speed (1 000, 2 000, and 3 000 min−1). The effects of the machining parameters on the average surface roughness and material removal rate were investigated. According to results, average surface roughness and material removal rate were affected by the nozzle feed rate by 87.15 % and 82.48 %, abrasive flow rate by 9.84 % and 13.49 %, and spindle speed by 1.09 % and 0.08 %, respectively. Optimization results that the nozzle feed rate should be 10 mm min−1, while the abrasive flow rate is 450 g/min and spindle speed is 3 000 min−1 in order to obtain the minimum surface roughness and maximum material removal rate.

Successful application of endovascular neurosurgery depends on high-quality imaging to define the pathology and the devices as they are being deployed. This is especially challenging in the treatment of complex cases, particularly in proximity to the skull base or in patients who have undergone prior endovascular treatment. The authors sought to optimize real-time image guidance using a simple algorithm that can be applied to any existing fluoroscopy system. Exposure management (exposure level, pulse management) and image post-processing parameters (edge enhancement) were modified from traditional fluoroscopy to improve visualization of device position and material density during deployment. Examples include the deployment of coils in small aneurysms, coils in giant aneurysms, the Pipeline embolization device (PED), the Woven EndoBridge (WEB) device, and carotid artery stents. The authors report on the development of the protocol and their experience using representative cases.The stent deployment protocol is an image capture and post-processing algorithm that can be applied to existing fluoroscopy systems to improve real-time visualization of device deployment without hardware modifications. Improved image guidance facilitates aneurysm coil packing and proper positioning and deployment of carotid artery stents, flow diverters, and the WEB device, especially in the context of complex anatomy and an obscured field of view.

Published: June 2016

Antibiotic resistance is one of the most relevant problems in the healthcare: the growth of resistant micro-organisms in healthcare settings is a worrisome threat, raising length to stay (LOS), morbidity and mortality in those patients.The importance of the antibiotic resistance and its spread around the world, gave rise to the activation of several surveillance systems, based especially on the collection of laboratory data to local or national level.The objective of this work is to carry out a review of the scientific literature existing on the topic and scientific activities related to surveillance on antibiotic resistance in countries bordering the Mediterranean Sea.Recent Data from European Centre for Disease Prevention and Control (November 2015) show, for different combinations bacterium-drug, an increase of resistance from North to South and from West to East of Europe; it is particularly worrying the phenomenon of resistance carried out by some gram negative, specifically Klebsiella pneumoniae and Escherichia coli to third-generation cephalosporin, often combined in opposition to fluoroquinolones and amino glycosides.Is particularly relevant the incidence of resistance to carbapenems by strains of Enterobacteriaceae (Klebsiella included). The resistance exerted by MRSA (Methicillin-resistant Staphylococcus aureus) continues to be relevant, albeit showing some decline in recent years. The incidence of resistance carried on by Streptococcus pneumoniae is stable and is mainly relevant to macrolides. Finally, a significant increase in recording relatively exercised by Enterococcus faecium to Vancomycin.Detecting, preventing, and controlling antibiotic resistance requires strategic, coordinated, and sustained efforts. It also depends on the engagement of governments, academia, industry, healthcare providers, the general public, and the agricultural community, as well as international partners. Committing to combating antibiotic-resistant microbes will support patient care, economic growth, agriculture, and economic and national security.
THE ICET-A SURVEY ON CURRENT CRITERIA USED BY CLINICIANS FOR THE ASSESSMENT OF CENTRAL ADRENAL INSUFFICIENCY IN THALASSEMIA: ANALYSIS OF RESULTS AND RECOMMENDATIONS
Authors: De Sanctis Vincenzo 
Published: June 2016

Introduction: In March 2015, the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A) implemented a two-step survey on central adrenal insufficiency (CAI) assessment in TM patients and after analysis of the collected data, recommendations for the assessment of hypothalamic-pituitary- adrenal (HPA) axis in clinical practice were defined.Methods: To ascertain the current practice for assessment of CAI in thalassemia, the Coordinator of ICET-A sent two questionnaires by email: i) The first to evaluate the current interpretation of basal serum cortisol level (first step) and ii) The second to evaluate the current usage of ACTH test and the variability in practice" (second step). Based on the surveys the core ICET-A group prepared the recommendations for the assessment of suspected CAI in thalassemia (third step).Results: A total of 19 thalassemologists/endocrinologists have participated in the first survey and 35 specialists participated in the second step questionnaire. The survey demonstrated a considerable variability in almost all aspects of relevant current criteria used for the diagnosis of CAI. A ROC analysis using peak value > 20 μg/dl (> 550 nmol/L), after ACTH stimulation test, was performed with the aim of identifying the optimal basal serum cortisol cut-off. The optimal threshold that maximizes sensitivity plus specificity for morning basal cortisol against peak post-ACTH value >20 μg/dl (>550 nmol/L) was 10 μg/dl (275 nmol/L).,Furthermore, the values associated with highest negative predictive value (NPV) and highest, positive predictive value (PPV) were 4.20 (115 nmol/L) and 18.45 μg/dl (510 nmol/L), respectively.Surprisingly, 20 specialists in thalassemia working in blood bank, thalassemia centres (day hospital), internal medicine, hematology and onco-hematology had poor knowledge and experience in testing for CAI and stopped filling the questionnaire after the second question. In contrast, 9 endocrinologists (8 pediatricians) and 6 hematologists working in collaboration with endocrinologists completed the questionnaire.Conclusions: While waiting more extensive adequately powered and targeted studies, physicians should adopt an acceptable policy for accurate assessment of HPA in TM patients. Regular surveillance, early diagnosis, treatment and follow-up in a multi-disciplinary specialized setting are also recommended. The ICET-A recommendations are reported in order to facilitate for interested physicians the approach to successful assessment of adrenal function in thalassemia. Key words: Thalassemia, adrenal insufficiency, pitfall in the diagnosis, ACTH stimulation test, guidelines.
