Abstract: The effect of using wastewater (WW) and treated wastewater (TWW) in irrigation on some faba bean plant and soil properties was studied under pots experiments. In this study, using nano hydroxyapatite (nHP) powders, which prepared by microwave heating based wet chemical method and its modification with humic acid (nHP-HA complex) as a sorbent for wastewater treatment (WWT). The nHP and nHP-HA complex were characterized by different techniques. The treatment process was carried out by the fixed bed column technique with a flow rate (80 ml/h) to treat 1liter. Heavy metals concentrations, total organic carbon (TOC), major cations and anions were determined before and after treatment. Moreover, some factors were used to evaluate the quality of WW for irrigation purposes. The results showed that TWW by nHP-HA was more suitable for irrigation than treated with nHP. This referred to a significant reduction of TDS, inorganic and organic pollutants that caused improved in TWW chemical properties. Pots experiment was conducted to study the effect of irrigation with WW and TWW by nHP and nHP-HA complex on some soil and Faba bean plant properties. Plant and soil analysis showed significant changes in plant and soil properties due to irrigation with TWW than WW. Furthermore, plant height, dry and fresh weight, number of leaves and photosynthetic pigments were significantly affected by irrigation with WW and TWW and some soil properties such as pH and EC were also affected.

Abstract: Background: Acute coronary syndrome (ACS) is a very common health and economic burden in the world and accounts for more than 1 million of morbidities annually. Deaths due to ACS are nearly half of all deaths. Nearly 15–20 million patients each year admitted to the emergency room (ER) with typical chest pain, two-thirds of theme will be found not to have an ACS, so rule-in and exclusion seems to be very important. Biomarkers mainly troponins complement the clinical suspicion of ACS with the 12-lead ECG, but a major drawback its late release in the blood stream after ACS and thus the need for serial cardiac enzymes and prolonged monitoring for the final diagnosis or ruling out, the need for faster diagnosis and safe rule out of the patients with suspected ACS has led to the discovery of new biomarkers. Such a new biomarker is Copeptin which is nowadays well understood as an important marker of endogenous stress. Aim and Objectives is to investigate the effectiveness of using copeptinin safely ruling out NSTE-ACS very early after onset of symptoms and to asses if it has a prognostic value on determining the size of infarction or not. Patients and Methods: Any Patients presented to ER with symptoms suggesting ACS within maximum four hours of symptoms onset and don't have any of the exclusion criteria. Results: This study included 86 patients presented to the ED with symptoms suggestive for ACS mainly typical chest pain. The mean age for current study was 56.71±7.11 years ranged from 37-75 years. Most of our patients were males (71%), 45 patients (52.3%) were hypertensives, 41 patients (47.7%) were diabetics, 41 patients (47.7%) were smokers and 31 patients (36%) had a history of ischemic heart disease. All patients presented within 4 hours from symptoms onset with mean 2±0.71hours, 1^st set of copeptin, troponin and CK MB withdrawn at time of admission, another set of troponin and CK MB withdrawn after 6 hours. 45 patients showed an elevated troponin with the 2^nd set while only 1 patients had a troponin positive with the 1^st set, copeptin was highly elevated in 43 out of those 45, sensitivity of copeptin in relation to troponin was 95.6%, while copeptin was high in 7% of the troponin negative group with a specificity 82.9%. The highly abnormal Copeptin showed a strong correlation with the peaked elevated CK MB 2^nd set (r=0.701), but there were no statistically significant difference between copeptin positive and negative groups regarding risk factors, ECG changes, SWMAs or impaired EF% in echo. Conclusion: Copeptin is a novel biomarker that showed a great sensitivity towards NSTEACS and may improve the early and safe rule out of ACS in low to intermediate risk patients.

Abstract: This study was conducted during 2016 and 2017 seasons for examining the effect of spraying boron applied via nano- technology at 0.0125 to 0.05 % as well as through traditional methods namely borax or boric acid each at 0.025 to 0.1 % on fruiting of Early sweet grapevines grown under Minia region conditions. The undertaken vines received three sprays of boron at growth start, just after berry setting and at veraison stage. Treating Early sweet grapevines three times with boron via nano- technology system at 0.0125 to 0.05 % or through conventional methods namely borax or boric acid each at 0.025 to 0.1% had a striking promotion on all growth aspects, photosynthetic pigments, N, P, K, Mg, yield, weight and compactness of cluster and both physical and chemical characteristics of the berries over the control. Using boron through nano technology system was materially superior than using it via traditional methods in this respect. Using boric acid was favourable than using borax in this connection. Meaningless promotion on the investigated parameters were recorded among the higher two concentrations of borax and boric acid namely 0.05 and 0.1% and nano – boron from 0.025 to 0.05%. Carrying out three sprays of nano boron at 0.025 % gave the best results with regard to yield and quality of early sweet grapevines grown under Minia region conditions.

Abstract: In this paper attempt was made to perform diagnostic and prognostic analysis of the event at January 17,2010. This case study represents a heavy rainfall event over Egypt. Although this event occur in winter season, its impact was very unusual for the all the season. It was found out that the 2010 event was due to interaction between tropical and mid-latitude systems. In general, the ECMWF (European Center for Medium Range Weather Forecasts) model among the global models and WRF (Weather Research and Forecasting Model) model with the BM (Betts–Miller ) convection scheme from the regional models performed better in predicting the characteristics of the event.

Abstract: This study was destined to investigate the efficacy of improved in-situ mulch rows in improving and sustaining plantain yields up to the 4th crop cycle. The trial was conducted at the Rivers State University of Science and Technology Teaching and Research Farm, Port Harcourt, Nigeria using six different banana and plantain clones/cultivars and improved life mulch rows incorporated on the three meter inter-rows and were cut back periodically. The in-situ mulch rows were planted with selected grasses and legumes. Growth and yield parameters were taken. The results shows that the manure from the in-situ mulch rows significantly increased and sustained yields up to the 4th crop cycle at (p<0.005) level of significance other than in the circumference at the last finger. On the growth parameters, there was also a significant difference amongst the clones in plant height, number of leaves and sucker production in all the crop cycles with the triploids scoring higher owing to their increased number of chromosomes and cell sizes. Bunch weights were found to be independent of bunch hand but increased with increase in finger number and size. The higher bunch weight of the triploids was attributed to fruit size and not the number of fruits which was higher in the diploids. This study has shown the usefulness of in-situ mulch rows in increasing and sustaining yields of different Musa spp up to the 4th crop cycle.

Abstract: The present study was aimed at determining the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) antibodies in pregnant women serum samples during antenatal care (ANC) in a private hospital in Port Harcourt, Rivers State, Nigeria. The study involved experimental design, administration of structured questionnaire and analysis of data. The analysis was carried out in the Medical Microbiology laboratory of the University of Port Harcourt, Rivers State, Nigeria for the periods of 6 months from March 2018 to August 2018. Blood samples were collected aseptically from ninety-five (95) subjects. These samples were stored and screened for hepatitis B, using ACON HBsAg ultra-rapid test strip, Hepatitis C using Swe-life HCV and human immune deficiency virus using HIV1/2 test strip. The study was a retrospective study that reviewed all clinical case records of HIV, HBV and HCV patients (pregnant women) seen in private hospitals. Information such as age, sex, marital status, educational status, number of sexual partners, sharing of sharp objects, transmission of the virus to the foetus, human immune deficiency virus, hepatitis B and hepatitis C status, treatment status, knowledge of the viruses were retrieved using a structured questionnaire. Data were analysed and presented in simple percentage. Findings from the study showed that 100% of the patients were females and 19 pregnant women (20%) were in the age group of 15-25 years, 71 pregnant women (74.7%) were in the age group of 26-36 years and 5 pregnant women (5.3%) were in the age group of 36-45 years. The prevalence of human immune deficiency virus (HIV) was 15.79%, hepatitis B virus was 11.58% while hepatitis C virus was 0%. In addition, human immunodeficiency virus and hepatitis B were significant found among pregnant women compared to hepatitis C. The study showed the prevalence of hepatitis B and human immune deficiency virus among pregnant women attending private hospitals. Therefore, routine screening for HBV and HIV should be carried out regularly. [Agbagwa, O.E. and Abarra, S. I.

Abstract: Forest fires create a myriad of environmental, social and economic impacts. The fire incidence prone areas has mostly the gymnosperms species like Pinus, Cedrus, Oak etc. which catches fire easily, while as the lots of medicinal species in the temperate regions also get destroyed. As a result leads to the ecological and economic loss to the state. The impact of this damage involves not only the amount of timber burnt but also environmental damage to forested landscapes leading, in some cases, to land and forest degradation and the prevention of vegetation recovery. However, further more improvement required to enhance the process of better assessment, monitoring and management of the forest resources of the planet earth. Forest fire is a perennial phenomenon in the state. Even as all the forest types are potentially vulnerable to fires with most of temperate and sub-tropical forests experiencing ground fires if winters go dry, it is the Sub – tropical Pine Forests (Chir Forests) spread over 1258.85 km² (3.4 % of total forest area of the state) that experience the heaviest annual forest fires during the dry months of March to June. Forests are not uniformly distributed throughout the state but are mostly confined to higher hills and interior valleys because the lower and more accessible areas, the forests have been cleared for cultivation and settlement. At the district level, Chamba has maximum area under forests and most of it is under very dense and moderately dense forests. The extent of forest fires in the state over the last ten years in the different districts are as total of 572 fire cases have been reported during 2008-2009 and the total area affected area was 6.586 ha, the affected area raised four times more till 2010, whereas 1906 incidences of fire occur during 2009-10; 870 incidences of fire occurred during 2010-11 meanwhile 168 fire incidences happened during 2011-12. In the year 2012-13 highest number of fire incidences (1798) occurred with the huge economic loss of 2,76,82,589 crore in this decade.

Abstract: The biological assessment of the Mayo Kaliao River was carried out from 2013 to 2014 using macroinvertebrates. The bioevaluation attributes were FFGs, P/R index, Channel Stability, Temperature, HBI, percentage of tolerant taxa and percentage of intolerant taxa to organic pollution. Channel stability revealed that, from the beginning of water flow until its drying up, the substrates are unstable. This instability is marginal and sub-adequate. The permanently high temperature promoted rapid degradation of organic matter and the hydrology enable a constant resuspension. The watercourse is strongly heterotrophic (P/R index varied from 0.33 to 0.43). This heterotrophy favored the domination of tolerant taxa to organic pollution and collectors-gatherers which feed on FPOM in suspension. The contrast observed during this study showed the necessity to reevaluate the degree of tolerance to organic matter in sudano-sahelian zone, their trophic levels, their food resource and their mode of food acquisition.
