    Aluminum is the third most abundant element, after oxygen and silicon, and the most abundant metal in Earth’s crust. It is widely used in buildings, construction, transport, packaging and general engineering due to its corrosion resistance, durability, insulation capability, structural strength and low-weight, making it the metal of the future. Aluminum is widely used in all UAE construction related projects; however, the sustainability and environmental performance of the aluminum production process is questionable. The production of this metal is associated with many environmental impacts which compromise the sustainable production of aluminum. Aluminum manufacturing is an energy intensive industry and a major contributor to Greenhouse Gases such as CO2, CFC, and PFC. This industry generates huge amounts of waste such as the Bauxite Residue from the Alumina Refinery process and the Spent Pot-Lining (SPL) from the Smelting process. One of the sustainable solutions is to create a sustainable metal whilst also making a positive net impact on the environment over the life cycle of aluminum products. This solution suits UAE because the aluminum industry is on upstream production, with less emphasis on the use of recycling and secondary aluminum production. As an effective tool to control environmental impacts and improve the environmental performance of any production industry, Environment Management System (EMS) is further studied with regards to the aluminum production process. This research investigates the efficiency of the EMS at UAE aluminum production industry to determine its ability to control the industry’s impact, and to attain sustainability standards. The aim of this research is to evaluate the efficiency of the existing EMS and to identify the factors affecting implementation of EMS in the UAE aluminum production. The implementation of EMS in the UAE aluminium industry is heavily affected by regulatory compliance and enforcement gap, transparent leadership, accountability, and human factors.

    The application of multi-sensor systems for the monitoring of machining processes is becoming more commonplace to improve productivity, automation and reliability. In order to enhance knowledge in this area of applications, this study proposes a novel approach for the continuous on-line condition monitoring of grinding operation using low cost infrared and visual imager alongside with more commonly used sensors i.e. AE sensor, accelerometer and dynamometer. To achieve this aim a multi-sensor system is developed and installed for the monitoring of grinding operation. The signals acquired and analyzed by the system include visual, thermal, force, vibration and AE under different grinding conditions. Image processing techniques are used to establish that an increase in sparks within grinding zone results in rise of grinding zone temperature, which in turn results in increased surface roughness. Signal processing techniques are used to establish that dressing of wheel is most influential factor for surface roughness of workpiece. Artificial intelligence is then used successfully on both infrared and visual data to establish an automated continuous on-line monitoring system for grinding operation with an accuracy of 95 percent.

    Solid waste management (SWM) has become an enormous burden for the governments of developing countries. SWM is a partiularly crucial problem in theDhaka, the capital city of Bangladesh. The Dhaka City Corporation (DCC) is the only formal organisation responsible for waste management. It estimates that up to 2% of the population of developing countries survive through informal waste-recovery activities. Thus, this study is aimed to assess the sustainable livelihood through SWM among the waste workers in Dhaka. This study collects primary data through a questionnaire survey on 436 poor waste workers living in the Dhaka city of Bangladesh. The samples are selected from the landfill, commercial and residential area based on the stratified random sampling technique. This study shows that  the analysis of structural equation modelling  achieves the required  level of validity, reliability and fitness where the values of Cronbach’s  alpha (œ) > 0.7; Construct Reliability (CR) > 0.6 ; Average Variance Extracted (AVE) > 0.5 ; Chisquare, Comparative Fit Index (CFI)  and Tucker –Lewis Index (TFI) > 0.90; Root Mean Square  of Error  Approximation (RMSEA) < 0.08 and chi Square /Degree of Freedom (Chisq/df) < 5 . The three latent exogenous constructs  namely source separation,  health hazards, and sustainable livelihood  are significant variables to achieve sustainable livelihood vis-à-vis poverty reduction. Using the econometric model, the study focused on the health awareness, welfare, income generation, employment opportunities of waste workers.

    Wireless technology becomes a fast developed research field in order to respond to our needs. It has various applications such as health care, emergency situations, industrial applications and home automation.  It has several challenges like security and quality of service. Sensor node has a limited energy related to its tiny battery. Hence, energy efficiency is considered as an important challenge in Wireless Sensor Networks (WSNs). This paper aims at describing the various routing categories and the different efficient routing protocols. Along with this, a new enhanced version of the VLEACH protocol based on selecting the routing path efficiently is also proposed in this paper. The efficient selection process is based on electing the Cluster Heads (CHs) and the Vice-CH according to the highest residual energy. In addition, it uses a cooperative routing between the CHs and Vice-CHs in order to reduce the network energy consumption. Implementation of Basic VLEACH and Proposed VLEACH is done using NS-2 Simulator. Simulation results show that the new scheme is more efficient than the original VLEACH protocol. This protocol will increase the lifetime of sensor networks. So the proposed work can be applied in various WSNs which are deployed in remote areas and recharging of sensor nodes is an issue.

    Paclobutrazol (PBZ) is a growth regulator used to control vegetative growth, stimulating the reproductive capacity of plants. PBZ has been widely marketed throughout the tropics to stimulate mango flowering. In the recent years, many reports showed that application of PBZ by soil drenching can cause permanent stunting of flushes, the vegetative and root growth of mango was reduced. The aim of this work was to determine the effects of PBZ on flowering of mango by foliar application. The commercial mango cultivar ‘Namdokmai-sitong’ was used in this study. The experiment was analyzed as a completely randomized design. There were 4 replications with 10 treatments. Foliar application at 15 days after pruning with PBZ at 0, 500, 1,000, 1,500 and 2,000 mg./L and repeated at 30 days with 0 and 1,000 mg./L. There was significant difference on the time to flowering, percentage of flowering shoots and panicle length. The trees receiving the PBZ at 2,000 mg/L were exhibited stunting of flushes and panicle malformation. This study suggests that the multiple foliar application of PBZ was effective in promoting flowering in ‘Namdokmai-sitong’ mango, can help early flowering and higher percentage of flowering shoots.

    The Tinibaouine region, located in north-eastern Algeria on the borders of the Batna-Belezma Mountains, is characterized by a semi-arid to arid climate with an average annual rainfall not exceeding 465 mm and an average annual temperature of around 22 ° C. This region is characterized by the cultivation of apricots as essential crop followed by that of olives, whose plots are all irrigated with the Tinibaouine spring water. These are 450 Ha of trees for apricot and 108 Hectare for olives which constitute the principal revenue of the citizens of this small village. This paper estimated the crop reference and actual evapotranspiration (ETO) respectively and the irrigation water requirement of apricot trees and olive trees. The long recorded climatic data, crop and soil data, effective water allocation and planning, the information about crop water requirements, irrigation withdrawals were computed with the Cropwat model which is based on the United Nations’ Food and Agriculture Organization (FAO), the Penman-Monteith method was used to estimate ETo. Crop coefficients (Kc) from the phenomenological stages of apricot and olive were applied to adjust and estimate the actual evapotranspiration ETc through a water balance of the irrigation water requirements (IR). The results showed that the annual reference evapotranspiration (ETO) was estimated at 3.71mm / day. The irrigation requirements were estimated at 35800 m3/ hectare for apricot, 6980 m3/ hectare for olive, also Irrigation needs estimated on land at 14185, 05 m3/ hectare for olive and apricot.

    The aim of this study is to contribute in irrigation scheduling by proposing adaptable models that are widely used for the estimation of reference evapotranspiration  in Herat, Afghanistan. Six well-known models, The Penman-Monteithm, Hargreaves, Hamon, Thornthwaite, solar radiation based  and net radiation based  were compared, and the pan evapotranspiration model was used as indicator. The pan coefficient  proposed by Pereira was used to convert pan evaporation  to pan evapotranspiration. Results obtained showed that, the evapotranspiration values estimated by all the methods were shown to be close to those of pan evapotranspiration in the second period (spring, fall and winter). However, large differences emerged in the first period (the windy summer), with the exception of Penman-Monteith. This method displayed a small difference only in June and July. Pearson’s correlation  showed that the estimates produced by all the simpler methods were significant correlated with those of pan evapotranspiration in the second period, but weakly correlated in the first period. The  Penman-Monteith method produced the lowest value of 1.3 mm day-1, based on the standard error estimation. The seasonally-based average difference between pan evapotranspiration and Penman-Monteith was smaller than that of the other methods in the first period, at 1.9 mm day-1. The  Penman-Monteith estimation rate was therefore closest to pan evapotranspiration. It is concluded that the methods that used wind factor are more adaptable than those not used wind factor especially in Herat, Afghanistan. The wind might be the reason of the differences between pan evapotranspiration and  Penman-Monteith in the windy summer.

    At the international level, it is recognised that environmental problems are best handled with the participation of all concerned citizens at the relevant level. However, the development of effective models for promoting citizen participation to solve environmental issues remains a work in process. With the goal of suggesting such a model, this study focuses on the system of Landcare in Australia, a nation-wide movement of community-based natural resource management that has been tackling Australian’s serious environmental problems. Through analysing the outcomes of in-field research in Australia, this study describes three characteristic elements of the Landcare movement: establishing a system and a spirit of multi-party partnership throughout the nation; securing coordinators, who with flexibility to adjust to each locale, support local groups; and maintaining a holistic support system from governments who respect the autonomy of local groups. Through the discussion, this study shows the strengths of the three elements such as the diversity of the financial sources; and the challenges regarding the provision of financial and coordinating support to the communities. Also, it shows that there are activities that local groups and their networks within the movement have carried out that aim to overcome these challenges. This indicates that it is effective to establish a program which has a system and spirit of multi-party partnership, secures coordinators, and maintains a holistic support system from governments, for promoting citizen participation to deal with environmental issues.

    Horizontal transfer of plasmid DNA was investigated under phytoplankton metabolites / zooplankton predation exposure condition, to obtain some basic information about the prosperity and decay of GMO (genetically modified microorganisms) in filed release was investigated in this study. Escherichia coli HB101, E.coli C600, E.coli S17-1, Pseudomonas aeruginosa PAO1 (gram-negative) and Bacillus cereus MC (gram-positive) as recipient strain of plasmid DNA, E.coli HB101/pBR325, E.coli C600/RP4 and E.coli S17-1/pSUP104 as donor of plasmid DNA, were supplied. As phytoplankton, Microcystis aeruginosa (cyanophyceae), Melosira varians (bacillariophyceae) and Scenedesmus quadricauda (chlorophyceae) collected from Lake Tega as donor of metabolites, were supplied. As zooplankton, Tetrahymena pyriformis (cilliata) and Philodina erythrophthalma (rotifer) collected from Lake Tega as predator were supplied. The results can be concluded as follows; 1) Phytoplankton metabolites leads acceleration of horizontal transfer between not only same strains but also different strain in spite of whether transmissible or not, 2) Zooplankton predation leads decrease of bacterial individual number and horizontal transfer of plasmid DNA, and 3) Horizontal plasmid DNA transfer is influenced greatly, because the natural ecosystem includes phytoplankton as producer and zooplankton as consumer in the same time.

    Arthrospira (Spirulina) platensis is an edible cyanobacterium that has been consumed worldwide as a nutrient source under the name spirulina. When preparing synthetic media for this microalga, boron is usually added to them. However, whereas boron is necessary for the N2-fixation-dependent growth of heterocystous cyanobacteria, boron requirement by A. platensis, which is non-heterocystous, has not yet been carefully examined. To examine the effect of boron on A. platensis, we prepared a boron-depleted medium in which borate concentration was below a detection limit (0.2 μM), as determined by the spectrophotometric quantitation with H-resorcinol. Using this boron-depleted medium, A. platensis NIES-39 was analyzed for changes in growth, dry biomass weight and the protein, chlorophyll a and C-phycocyanin contents. Experimental results showed that removal of boron from the growth medium had no detectable effect on them. A control experiment with a heterocystous cyanobacterium Anabaena sp. UTEX 2576 showed that the growth of this cyanobacterium was suppressed in a boron-depleted medium. These experiments demonstrated that boron was not required for the growth of A. platensis. Our results indicate that boron supply is not necessary for the propagation of A. platensis even in the regions where boron deficiency in the soil deteriorates the growth of common crops. Use of boron-free media would also be helpful to improve the reproducibility of sensitive physiological experiments such as metabolome analysis, because precipitation of the insoluble salt manganese borate, which may reduce the concentration of Mn2+ in the medium, does not occur in boron-free media.​

    Agricultural food industry in Thailand generated incomes about 10.5% gross domestic product (GDP) of the country in 2015. The demands of agricultural food products around the world has been increased for years. Agricultural food products from Thailand could not be exported as many as the growth of market demands because of the limitation of food safety guarantees. Analysis and Critical Control Points (HACCP) is a minimal requirement for exported food products to assure food safety. Not all Thai companies in agricultural food industry received HACCP certifications. There might be some challenges that obstructed the implementation of HACCP in the food industry of Thailand. The objective of this research was to identify challenges faced by companies in Thailand when implementing the HACCP in agricultural food companies. An online survey was conducted to collect data from companies in food industry. Twenty companies completed the survey. All twelve challenges proposed in the research survey were experienced by participating companies during the HACCP implementation. The challenges, identified as barriers to implement HACCP, were a lack of employee engagement in HACCP implementation, a lack of employees who understand the HACCP system, and a lack of advanced statistical knowledge. The results suggested companies to develop an effective communication plan to convey the HACCP implementation plan to employees at all levels and to provide training programs, related to HACCP and statistics, to fulfill knowledge and skills required in the HACCP implementation.

    The adequacy of caloric intake is crucial for all critically-ill patients in Intensive Care Units because energy expenditure is higher in these patients compared to normal patients in general wards. Adequate calorie intake will promote positive outcome to the patients while inadequate calorie will lead to malnutrition which will increase the length of stay. The objective of this study was to determine the adequacy of caloric intake received by critically-ill patients in the general ICU in Malaysia. This was a cross sectional study which used a proforma adapted from ICU protocol. There were 132 participants involved in this study. The descriptive statistic and independent t-test were used for the statistical analysis. The results showed that 75.8% (n=100) received adequate or more than calorie prescribed while 24.2% (n=32) received calorie less than the given prescription. Patients that received early feeding were 72% (n=95) and late feeding were 28% (n=37). The continuous feeding method was most commonly used in early feeding patients from Day 1 to Day 3. There was an association between the adequacy of calorie intake and the length of stay (p<0.05). Findings obtained from this study will provide information for the nurses and other health care providers to improve the management of patients so that all patients will receive adequate caloric intake during their stay in ICUs.

    The unsuitable conditions as the result of a decade of war had made it difficult to raise the level of physical activity among the youth in Iraq. Lack of awareness, as well as misconceptions about diets and the concept of physical activity among young people and the society in general especially pertaining women involvement in sports had made this matter worsen. Hence, designing home-based intervention program to enhance the physical activity level among the sedentary undergraduate female students in Iraq is crucial. The home based intervention program consists of simple exercises to be carried out at home and some nutrition information on balance diet. Forty-four sedentary undergraduate female students aged 18-22 years old were selected as subjects in this study. They were randomly selected from Northern Region of Iraq. The subjects completed a 12-weeks home based intervention program that combining simple exercises and diet information. Their daily physical activity level was measured using a pedometer. The results showed that there were a significant difference between the steps counts from pre-test to post-test1 (6-weeks) and pre-test to post-test2 (12-weeks) (p<0.001) in the experimental group. The mean steps increased by 6825.73 steps from pre-test to post-test1, and 9007.71 steps from pre-test to post-test2. Additionally, the results of these two groups were different in test (time) pre, post1 and post2 (F(2, 84)= 713.00, P<0.05, ɳ2= .944). Based on these results, it was concluded the 12-weeks home based intervention program was effective in enhancing physical activity level among sedentary undergraduate female students in Iraq.

    We have found out that biomass charcoal powder (BCP), which is prepared from plant biomass wastes by pyrolysis at low temperatures under nitrogen atmosphere, imparts organic solvent resistance to proteins by using BCP as a protein carrier. α-Chymotrypsin (α-CT), which was used as a model protein, was sufficiently adsorbed onto the surface of BCP. When free α-CT and BCP-adsorbed α-CT were immersed in acetonitrile containing 5%(v/v) water, they catalyzed the transesterification of N-acetyl-L-tyrosine ethyl ester (N-Ac-Tyr-OEt) with n-butanol (BuOH) to produce N-acetyl-L-tyrosine butyl ester (N-Ac-Tyr-OBu), which did not proceed in an aqueous solution, where α-CT worked as a hydrolase. The initial rate of transesterification catalyzed by BCP-adsorbed α-CT was strongly dependent upon the kind of BCP, and was about fifty times higher than that catalyzed by free α-CT when bamboo charcoal powder was used as a carrier.

    In fingerprint recognition technology, ridge-frequency and –orientation step are utilized to identify trait pattern of ridge/valley features of the fingerprint by separating foreground and background of the fingerprint image and specifying the directional pattern of the ridges and valleys. The ability to determine the patterns help us as well to select a particular area to be utilized forth. Meanwhile, core-point is needed as a reference point in region of interest (RoI) cropping process. For example, if a desired region is a square-form area, core-point can be as a central of the RoI. Thus, we just need to lay down two diagonal side of the selecting area. In conclusion, it is obvious that the superiority of these three steps can be exploited in RoI step.

    Studies on the changes of physical activity patterns demonstrated that physical activity rates decline sharply in adolescence and goes on well into adulthood. Psychological readiness, not physical readiness and facilities, is likely to be the main barrier to activity for most of the people. This seems to signify the importance of designing interventions to improve psychological factors related to exercise behavior willingness. This study evaluated the effect of an intervention contained strategies related to psychological factors of exercise behavior. Fifty-six sedentary adolescents completed an assessment at baseline, 2 months, and 4 months. Experimental group participants received the intervention lasting for 16 weeks and consisting of a 30-minute session every week with the aim of raising learners’ awareness about the factors affecting intention to physical activity. Control group attended physical education classes based on the guidelines of the Ministry of Education. Changes in psychological variables were compared between groups using analysis of two-way repeated measure ANOVA. The interaction between group and test was statistically significant, F (2, 108) =127, P =.01, η2=702). There was a significant difference between the scores of self-efficacy in the 3 times measurements in the experimental group. It can be concluded that the stage-based intervention had a significant positive effect on self-efficacy hence enhancing sedentary students’ intention towards physical activity.

    Pain, a common symptom for patients in medical wards, can be relieved by effective pain management, with nurses playing a vital role in this regard. A study was undertaken to determine the knowledge of nurses on pain management and to examine the factors that influence their acquisition of such knowledge. A total of 143 medical ward nurses (representing 60% response) in a government referral hospital in Malaysia participated in the study. Data from this study derived from a set of questionnaires were analysed using 2 x 2 contingency tables and the chi squared test with Yate’s correction. Approximately two thirds of the nurses were deficit in knowledge regarding pain management, registering a mean knowledge score of 40.5 out of a possible 100 points. There was no significant association between the level of knowledge on pain management and demographic characteristics such as age and work experience. There was also no significant relationship between the level of knowledge on pain management and the pain courses attended. A better understanding of the factors that affect the acquisition of such knowledge could provide useful information that can be incorporated in an improved educational program on pain management for nurses.

    To obtain the characterized source model for prediction of strong ground motions, the ground motion generation area and rupture geometry of an inland crustal earthquake from near-source ground motion records has been estimated. An earthquake, with a magnitude of 4.3 ML and a focal depth of 18 km occurred on September 3, 2015 at 30.45N, 28.44E in the Western Desert of Egypt about 60 km south of El-Dabaa city. This earthquake is the first instrumentally recorded earthquake occurring in this area in several decades. The waveform data of this event has been used for source characterization and ground motion modeling. The present work describes the results of a preliminary study conducted to obtain fault plane solutions of this earthquake from waveform inversion and P-wave polarity. For this purpose, the source parameters related to the strong ground motion were estimated by waveform data and first arrivals recorded by the Egyptian National Seismic Network (ENSN) are used to arrive at focal mechanism solutions. Fault plane solutions for the main shock indicate strike-slip motion. One nodal plate strikes about 330°, is nearly vertical, and indicates right lateral slip. The other nodal plane strikes about 240°, dips very steeply NW, and indicates left lateral slip. Also the peak ground acceleration (PGA) at the El-Dabaa site has been simulated by taking into account an accurate estimation of the source characterization, the path attenuation model, and site amplification. The results have been validated using an actual recording of PGA at one ENSN station that recorded strong ground motion.
