Effective communication complements managerial effectiveness in organizations and is also a means of achieving organizational objectives. The settings in large organizations often makes effective communication difficult. One source of this lies in the characteristics of organizational structure. This study confines to the impact of organizational structural variables on effective communication in organizations. The communication channels created by the organizational structure serve specific functions through downward, upward and lateral communication. Thus, an organization’s structure must facilitate this effective flow of communication. This study examined the relationship of selected variables of organizational structure and the informal structure to effective communication flow among the managerial ranks at GTBank in Kaduna Nigeria. The organizational structural variables examined were specialization, departmentalization, hierarchical level, a span of control, spatial dispersion, formalization and centralization, and the informal structure. Additionally, the demographic factors of gender, age, race, position, years of company experience, and emplacement were investigated to determine their impact on communication effectiveness as well as the differences among the various groups classified by the demographic factors

Extraction of commercial mineral salts from the lake brine requires thorough knowledge of the brine phase chemistry. In this paper a solubility software (PHREEQC) has been used to predict which salts, their respective yield and the order in which they can crystallize from Lake Katwe brine. The brine solution was evaporated to supersaturation by removing 51 moles of water at 27.6°C. Thereafter, supersaturated solution was subjected to temperature variations ranging from -30° to 130°C. After removal of 31 moles of water, Thenardite equilibrates with the solution followed by Trona (33 moles), Burkeite (35.5 moles), Halite (36 moles) and lastly Glaserite (41.5 moles). At subzero temperatures, Mirabilite emerged with the highest Saturation Index (SI) followed by Sylvite and Halite. During evaporation, the PHREEQC model predicts a mineral precipitation sequence that starts with Thenardite followed by Trona, Burkeite, Halite and Glaserite. Based on the yield results, Halite, Thenardite, Burkeite, Glaserite, and Trona are the feasible salts that can be extracted, the latter being the least feasible. The ideal parameter ranges of pH, alkalinity, temperature, brine concentration factor and ionic strength were determined.

The widespread use of applications services will only be accepted by users if their understandability (usability) is of acceptable level. It is therefore of high interest to be able to estimate, or to predict the usability (usability attribute) of a system under observation. Clear and visible navigations, consistent styles and color, concise content, appropriate help and searching means easily accessible are various usability factors to affect end user’s satisfaction. Mobile applications are now a de-factor standard for judging, using the medical or other systems to be built in the current era of technology. Due to ongoing research and improvements in mobile technology, the data/ information and their applications contained in this context are constantly evolving and are subject to the professional judgments and interpretation of the practitioner due to the uniqueness of a clinical situation. By usability in mobile App (mobile computing) we exactly mean to have an effective, efficient and at the same time customers satisfaction via feasible use of the mentioned APP. If the usability of these APPs under discussion is that of valuable standard, the users of these mobile applications can effectively attain all their tasks. In this work we have highlighted the importance of usability in the educational applications in mobile. That is, our study here evaluates the usability of selected mobile educational applications regarding two subject categories maths and reading skills to identify the usability problems found by the participants. After evaluating usability via testing these mobile applications on school children the comparisons are made between results gathered from usability and learning evaluation to prove our hypothetical statement that usability has a strong impact on learning.

Slab supported by a soil media is a widely used form of constructions in the civil engineering. When a cavity forms -due to gypsum dissolution- below the slab, a loss of support case or weak supporting condition will occur. In this paper, an experimental model has been tested in the laboratory to discus the load deflection curve of a real case of slab on soil. A good agreement obtained when simulating the experimental result by a numerical analysis program (ANSYS). Parametric studies have been made to show the effect of forming a cavity of different depths, various diameters, changing the slab thickness, and variation the concrete compressive strength. From this research, it can be concluded that forming a cavity of (D/T) = 0.13 (cavity depth to total depth of soil) causes to reduce the slab capacity by (148%) when comparing with a soil without cavity, and using a cavity of (d/B) =1 (cavity diameter to slab width) leads to reduce the slab failure load by (212.5%) when comparing with a soil without cavity. The failure load versus cavity depth and diameter has been obtained. The concrete compressive strength vs failure load of slab has been drawn.

Audit is an integral part of the modern business environment. Audit develops, from financial audits to other types of audits, such as management, operational, performance, quality, environment, human resources, information technology audits and others. To state the level of conformity, the auditor requires the collection and testing of audit evidence. Audit evidence can be in the form of physical evidence, documentary evidence, testimony evidence, and analyst evidence. The increasing use of information technology/computers in data processing organizations has made changes in the form of audit evidence. If audit evidence as a result of a computer process cannot be seen then it is impractical for the auditor to do manual testing, so that the auditor must consider the use of Computer Assisted Audit Techniques.

The popularity of muslim fashion in Indonesia made its way to the mass media, particularly into the television screen as a part of Indonesian popular culture. One of them is Fair&Lovely Commercial which featured a female model wearing muslim fashion. The commercials featured visual elements and narratives that brings a question about the image and identity of nowadays Indonesian muslimat, as television commercials can represents a particular identity within its visuals. This paper focuses on a visual analysis of Fair&Lovely television commercial, a whitening lotion showing a model wearing muslimat fashion to see how the commercial represents the image of nowaday’s Indonesian young adult muslimat with the approach of semiotics in the form of intersign relation of metaphor-metonymy. The result shows that the Fair&Lovely commercial tries to communicate an image representing a mixture of idea between the Islamic Syar’i values and the Western concept of female and femininity in the form of liberal feminism as a part of nowadays Indonesian muslimat identity.

The occurrence of a landslide disaster is one of the most frequent disasters in Indonesia, including in East Kalimantan on roads connecting Samarinda Balikapapan especially in Bukit Soeharto Forest Highway km 38 Sungai Merdeka district Samboja and km 69 Batuah district Loa Janan, it is necessary to take a research steps to determine the causes of landslide disaster and to know how to tackle the causes of the landslide. Based on the analysis at the location of the research that the land texture in Soeharto Hill Forest Park area is yellow Podzolic soil type, Latosol and Litosol (15%) and Alluvial soil (10%) with parent material in the form of folds of hill and the structure of the soil is clumped and its consistency is flat. The topographic state of the field is bottom to bumpy to the slope of 10-45%.Referring to the general nature of soil chemical physics, most soil types in the Bukit Soeharto Forest Park area have a high degree of erosion sensitivity with very low land productivity, so it is appropriate to be designated as a conservation area. The potential for ground motion on the slope depends on the soil condition and its composition and one of the geological causes of soil movement is rock weathering, because it is in high intensity of rainfall and sun irradiation makes the rock weathering process more intensive. Rocks that often weathering will cause a decrease in rock strength that ultimately forms a layer of weak rock and thick residue soil. If this happens on the slopes it will be critical. The location of the study is a hilly area that forms a slope of land with an average slope of 25 to 75 degrees and is composed by a pile of soil formed by physical and chemical weathering on rocks or more compact soil has the potential to move or landslides. The cause of a landslide disaster along the Balikpapan-Samarinda road in Soeharto Hill Forest Park is due to high rainfall and deforested land cover deforestation.

A air solar collector is a thermic system that uses the solar energy to produce heat warming up a fluid circulating inside the system. There are two types of solar collectors that can be used as an air conditioning system in a habitation: water solar collectors and air solar collectors. In this work, we studied air solar collectors which is based on the circulation of heated air inside a serpentine for warming or cooling a house. A new analytical approach based on the F-chart method have been proposed to calculate the solar covering rate of the heating air requirements in the habitation. Besides, the overall efficiency of the system depends especially on the quantity of heat stored by time unit in the storage tank of the installation.

Indonesia is one of the countries that has large coal reserves in the world, but its utilization is still limited to the manufacture of briquettes and as fuel for electricity generation. On the one hand the results of the study indicate that activated charcoal can be made from organic and inorganic materials mentioned in high carbon content. In this case it is as raw material for making activated carbon because it has a high carbon content. Meanwhile, the textile industry is one of the industries that developed in East Kalimantan, especially Samarinda. Where liquid substances from chemicals can increase the concentration of pH, TSS, BOD and COD if directly discharged into the environment without first processing. One way to reduce levels of pollutants from liquid waste is by means of adsorption using activated carbon. This study aims to determine the capacity of activated carbon to the pH, TSS, BOD and COD values in Samarinda waste cloth wastewater. Low rank coal is carbonized at 600 for 1 hour, then activates physics at 800 for 2 hours. As much as 700 ml of Samarinda waste cloth industrial wastewater is adsorbed with activated carbon from low rank coal with a mass of 5, 10 and 15% by mass to waste with an adsorption time of 120 minutes. The best results are obtained at a mass of 15% with a percentage decrease or % removal in conditions: pH value 7.67; TSS 92%; BOD 47.1% and COD 39.26%
