This review aims to summarize the possibility for practicing intercropping in aquaponics to produce high-quality fruits, vegetables and fish without any chemical fertilizer and minimum ecological impact for a sustainable agriculture. Although many studies have addressed about aquaponics for producing high-value crops such as tomato, cucumber, and lettuce, there is still a lack of complete information to support the development of intercropping in aquaponics and limited focus on its commercial implementation. Moreover, this study will focus first on the requirements for inserting intercropping in aquaponics and technical improvements needed to adapt as potential for sustainable food production system to increase productivity around the world, especially in countries...

Few authors described this junction in detail i.e., the Duodenojejunal junction (DJJ) pressure got reduced on duodenal muscular activity whereas it got augmented on jejunal muscular activity. These results suggested possible reality and the presence of anatomical sphincter at DJJ. Methods: DJJ was studied through direct dissection of 20 cadavers whereas the specimens were histologically examined and stained with H&E stain. While the radiological examination was performed for another 10 cadaveric specimens using plain X-ray technique. Barium was injected into the pyloric canal and a tie was applied into the jejunum so that it allows only the barium is present in the duodenum, DJJ and at a few centimetres of jejenum. Transverse and longitudinal sections through DJJ were incised and stained by H&E stains. Results: DJJ was narrower and more contracted than duodenum or jejunum. It also possessed one or two depressions and covered by arterial branch that originated from superior mesenteric artery termed as ‘duodenojejunal junction artery’. DJJ was felt by touching and found to be thicker and tough than duodenum or jejunum. Its mucous membrane lining was packed into ‘DJJ rosette’. The length of DJJ among adults is in the range of 0.6–1.2 cm. The circular muscle layer was found to be clearly thickened at the junction when examined using microscope. Further, the longitudinal muscle coat was also very thick at the junction when compared with the same coat in duodenum or jejunum radiologically. DJJ was found to be narrower and constricted whereas duodenum was wide. Jejunum was similar to duodenum. Conclusion: The thickened tough circular muscle, mucosal rosette packing and narrowing and contraction at DJJ refer to the possible presence of anatomical real sphincter at DJJ which got augmented when high-pressure is applied in this area. So, the corresponding results suggest and support the study hypothesis

Based on the advantage of the new communication technologies, Dhi-Qar local government sought to implement and adopt these technologies in the public sector. Regrettably , since 2003 most of the electronic services initiatives have been neglected or have not been used. In fact, pre-implementation (adoption) is essential for successful electronic health implementations. Serving patients in the hospitals through an integrated electronic Health system requires an understanding of the behavior of the Health workers (such as Nurse and Doctors) as well as the factors that influence their acceptance and usage of technology. Thus this study is intended to identify the main factors affecting on the adoption of the electronic health record in Iraq. The study will examine user acceptance and use of technology, in the Technology Acceptance Model (TAM). The quantitative method is the main approach of collecting the raw data from the respondents. This study concentrates on the staff who works in the main hospital in Dhi-Qar because this province is the first local province that implemented many electronic projects. A total of eight questionnaires were distributed but only 61 questionnaires were returned. As for the data analysis, the present study used second generation technique (Partial Least Squares) to analyze the self-administration questionnaire as well as use SmartPLS V.3 as an instrument. The results indicated that there is a significant relationship between Ease of Use-> Usefulness, Usefulness-> Attitude, and Attitude-> Adoption of EHR. The results also showed that influence demographic do not influence on the adoption of EHR among health workers in Dhi-Qar Hospital. These finding may help decision makers in Iraq government to improve future implementation of e-health services.

While the threat of a conventional explosion charge is defined by two equally important elements, the charge quantity (weight), the standoff distance between the blast source and the target. Furthermore, most casualties and injuries sustained during explosions are not only caused by the pressure or heat resulting from a charge detonation. But also, by fragmentation of walls, shattering of windows, and non-secured objects that are propelled at high velocities by the blast. Thus, protection of critical structures against blast load has become a critical issue. The research objectives were to increase the building impulsive capacity against a blast load that is applied on their facade without any modification in the building structure; these objectives were achieved using a protective panel as a barrier between the blast load and the building. Herein the research considered a study to achieve a panel design that could prevent a blast wave from reaching the building structure and minimizing the pressure behind the panel, besides a withstanding panel against consecutive explosions after the main blast. Furthermore the research investigate the alternation of design parameters to achieve the desired panel design including the filling material, thickness of panel's plates and separation distance between the front and rear plates. This paper includes six different models to be tested against a breaching charge of 50 kg of TNT at 1m standoff distance. The design of Protective panels consists of two steel plates with 350 mm gap. The structural design of the panel includes plate thickness, distance between front and back plate and filling material. Various panel designs were examined with and/or without different filling materials. Moreover, strengthen mechanism is implemented for plates using shear connectors and horizontal stiffeners. Panel design approach is accomplished using the finite element analysis through ANSYS AUTODYN. Eventually, the first three models have a large deformation, while the fourth and fifth model resulted in a medium deformation, finally, the sixth model resulted in a significant small deformation recorded 64mm; this model is committed as the most suitable panel design for protecting building against blast load. In conclusion the deformation decrease through the increase of plate thickness and the usage of concrete as filling material, as well as the strengthen mechanism using horizontal plates.

It performs three motions including surge (forward-backward), heave (up-down), and pitch (tilting). The suggested novel design is inspired from Stewart platform, a kind of parallel manipulator, distinguished for its high stability, and rigidity, but a narrower workspace compared to serial manipulators. Stewart platform provides six degrees of freedom, which are more kinds of motions than needed for testing humanoids balance. For this, Stewart platform is optimized to perform required motions to test humanoids balance of surge, heave, and pitch, by reducing the numbers of actuators from six to four, and re-configuring joints and links connecting the platform to its fixed base. While four actuators are sufficient for three degrees of freedom, 4 th actuator was added for wider stability range, which adds the possibility for 4 th motion of rolling. Mathematical analyses are conducted for the suggested novel design including kinematics, Jacobians, and dynamic modeling using both Lagrange formulation and Newton Euler methods, those analysesare based on the side view projection of the platform. Different control techniques were considered including model based controller, and independent joint controller. MATLAB Simulink was the software environment simulation has been conducted in, where S-function tool is used to replace the plant through its derived dynamic equations for the purpose of testing model based controller. CATIA software was used to 3D model the new design, and to manipulate its parts observing its motion. CATIA was also used to conduct structural analysis of the platform.A prototype has been built and controlled to demonstrate the new design performing surge, heave, and pitch motions.Prototype has shown high rigidity, and high stability. The new design can be considered for various types of applications other than testing humanoids balance, including simulators,and machining technologies.

The study adopted descriptive survey design using a population of 47 teachers. Three research questions and three hypotheses guided the study. The instrument for data collection was Total Communication Questionnaire (TCQ). Data collected were analyzed using mean, standard deviation and student t-test. Findings of the study showed that teachers perceived the use of Total communication as a technique that would improve the academic progress of SHI in schools. But most of the teachers found the technique difficult to use, they need time and training to apply the technique. In light of the findings, the researchers recommend that the institutions that prepare teachers should train teachers on this technique in order to improve their performances in the school.

Common bean (Phaseolus vulgaris L.) stands out as one of the main crops produced in Brazil, an agricultural product extremely appreciated by Brazilians. Planting of crops associated with irrigation is a viable alternative, among cultural practices, in improving productivity. The objective of this study was to verify the effect of the presence and absence of dead cover (surface straw) and of different irrigation slides on the development and productivity of the bean crop. The soil used does not present evident erosion, with very small granular structure, very porous, soft, friable, plastic and sticky, excessively drained consistency, being classified as Red Latosol Eutrophric typical clay texture. The experimental design was divided into subdivided plots, with four replications, with two plots with and without mulch on the surface, and subplots with 5 irrigation slides: 25, 50, 75, 100 and 125% of daily real evapotranspiration. To evaluate the productive agronomic characteristics, only the two central rows of each plot were considered as useful area, scoring 0.5m at each end. The evaluated parameters were: fresh mass, number of grains, number of pods, mass of 100 grains, production. Quantitative data were submitted to analysis of variance (ANOVA), followed by regression analysis. Conventional planting presented lower results than no-tillage in the characteristics evaluated, except for the production that obtained very similar values in both systems of planting. The no-tillage system provided better yields for the bean development, so that 100% irrigation would be recommended for the farmer.

Semen quality post cryopreservation have been associated with many factors such as impending storage intervals, source of sperm, cryopreservation protocol and the most important is the type of extenders used. OBJECTIVE: This study aimed to evaluate the extending capacity of four different types of extenders namely, AndroMed ®, BioXcell ®, Triladyl® and Tris-egg yolk in terms of motility, viability, morphology, DNA integrity, plasma membrane integrity and acrosome integrity of post-thawed bull sperms. Three healthy matured Brangus-Hereford bulls were selected for this study. MATERIALS AND METHODS: Twenty four semen samples were collected using an automatic electro-ejaculator and semen quality was analysed using Computer Assisted Semen Analyser (CASA). Eosin-Nigrosin (EN) staining technique was applied to evaluate the morphology, viability and acrosome integrity whilst sperm DNA integrity was evaluated using modified acridine orange stain and hypo-osmotic swelling test was applied to evaluate sperm plasma membrane integrity. RESULTS: Amongst the four extenders, AndroMed ® resulted in superior extending capacity to sperm motility, morphology, DNA integrity, plasma membrane integrity and acrosome integrity. BioXcell ® and Tris-egg yolk extenders had the highest capacity to protect sperm viability. Triladyl ® showed lowest extending potential capacity to bull sperm. CONCLUSION: From the present study, AndroMed ® can be considered as the best suitable extender for bull sperm cryopreservation. BioXcell®, Triladyl® and Tris–egg yolk based extender can be still applied, but there is a need for more studies in future to improve their extending potential capacity.

While more resources have been directed to the sub-national levels since the adoption of the federal system in 1991, the lack of transparency and predictability surrounding these transfers has undermined the role of federal transfers to promote regional convergence and reduce financial inequality. Objective: The objective of this the paper is to contribute to the efforts of designing a transparent transfer formula that enables an efficient and equitable distribution of federal fiscal fund between the states. Accordingly, different approaches for constructing different indexes to account for state expenditure needs and state fiscal capacity, and for equalization of the states' fiscal gap, are outlined. Based on these constructed indexes, the study suggested alternative simulations of equalization transfers using both fiscal needs and fiscal capacity to measure the fiscal gap so as to mitigate the disparities among states. Results: The results of the simulations, and Lorenz curve ranking and Gini Coefficient index, suggest that the government should base the transfer program on the fiscal gap measured by the difference between states fiscal needs, approximated by an augmented state needs index, and the state fiscal capacity, approximated by a poverty index. Conclusion: The recommended scenario is found to reduce the fiscal inequality between the states to its narrowest and results in conspicuous welfare improvement, compared with the currently used formula distribution.

The intense human activity added to the natural activity leads to the generation of aerosols which are composed of particles of very varied sizes. In particular, fine dust which constitutes a significant factor of pollution involving a deterioration of the air quality. The urban zone needs clean air to assure a public health. To achieve this goal, we need to enrich our knowledge on the sources and the impacts of the atmospheric pollutants. Understanding the sources, the composition and the mode of transformation of the atmospheric pollutants is the first step in air quality monitoring. Methods: The study and control can be achieved by using adequate nuclear techniques analyses. The aim of this work is to study air pollution in urban zone of Algiers for the evaluation of the contents of heavy metals in various selected sites. A sampling campaign was carried out during period 2005/2007 in three sites in the Algiers city: Bab El-Oued the High Casbah and Mustapha Bacha. In order to identify and quantify their concentrations, nuclear techniques such PIXE (Proton Induced X-ray Emission), ED-XRF (Energy Dispersive X-ray Fluorescence) and the INAA (Instrumental Neutron Activation Analysis) are used in this study. These techniques are powerful tools used in air pollution monitoring for the determination of trace heavy metals. We identified at the same time 18 elements (Results: the concentrations of the elements Hg, Co, Ni, Cr and Ag vary around 2 ng/m 3. The concentrations of element Zn vary over a wide range from 3 ng / m 3 to more than 500 ng / m 3. A large values of Pb were measured (5000 ng/m 3 , 8000 ng/m 3) and 200 ng/m 3 for Cu. The element Fe appears in all analyzed filters. The concentrations range from low level to high level (8000 ng/m 3). Conclusion: the high level measured concentrations show the significant air pollution in urban areas. The major emission sources identified were classified as sea spray (SS), suspended soil and vehicle emissions (vehicle emission VE, diesel and petrol). This analysis allowed us to deduce some significant sources affecting the receptor sites. Among these pollutants one finds heavy metals contained in the suspended matter.
