The need for man and his interest in conditioning is due to ancient times. for example, ancients enjoyed drinking cold water without having any kind of ice in their countries by putting water in pottery vessels and leave them on the roofs of their houses at sunset and long nights, Dry desert air vaporizes the water that passes through the pores of pottery vessels and the water inside it becomes cold. The Romans and the Greeks used their slaves to bring the snow from the mountain tops and then store it in huge conical pits in the ground, lined with leaves and covered to use it when needed. Also the great Alexander used this natural ice to cool wine barrels that he offered to his soldiers in every battle they won. Emperor Nero was always offering chilled food at his concerts. Hundreds of slaves were used to store the natural ice in the vaults of his palace. People continued to use natural ice only as a way to cool their drinks for a long time.

The blended amine viscosities of N-Methyldiethanolamine and monoethanolamine (MDEA+MEA) are measured for temperature range from 293.15 to 413.15 K. The total amine strength in the solution is maintained at 0.2, 0.3 and 0.4 mass basis. Temperature range 293.15 to 303.15 K is performed with cooling system to achieve the lower stable temperatures during the experiment. Operating pressure is maintained at 1 bar for temperature range 293.15 to 353.15 K and 4.5 bar for higher temperatures. Measured viscosity data is compared with available literature data as well as with modeled data by Grunberg and Nissan model. Earlier viscosity values are available up to 353.15 K for some blended amine concentrations. Therefore, this study is given highly importance for gas absorption process while developing regression models for reacting systems in gas separation. The average absolute deviation between measured viscosity values and viscosity calculated by regression model is around 2.1%. Therefore, measured blended amine viscosities are in good agreement with the predicted viscosity by regression model which is given by Grunberg and Nissan equation.

Mathematics plays a vital role in science and technology development. Its usefulness cannot be denied but most of the Filipino students perform poorly in the subject. Several factors were identified to influence student’s achievement in mathematics and one of the identified factors in the student’s attitude towards it. This study examines the influence of gender, mathematics anxiety which has to have attitudinal component, and the interaction of these two variables on the mathematical achievement of the student. 390 freshmen college students were surveyed to determine their anxiety scores when grouped according to grade, future, in-class and assignment factors. Independent sample t-test result showed that no statistically significant difference in the mathematics achievement between the male and female respondents can be concluded. Regression analysis reveals that mathematics anxiety is a predictor of achievement in mathematics and Analysis of covariance result implies that the influence of gender and mathematics anxiety when taken together on the mathematical achievement of the students is not significant.

Ablation is a minimally invasive procedure used in the treatment of small tumours. Tumour sizes of about 3 cm are now been effectively treated with thermal ablation therapy using either microwave ablation or radiofrequency ablation. The impact of the slot position on a coaxial antenna on the extent of thermal lesion at the tumour site was investigated numerically in this study by varying the slot distance from the antenna tip using COMSOL Multiphysics as the modelling tool. The coaxial antenna size investigated has a diameter of 1.79 mm, with a central conductor diameter of 0.29 mm and Tefzel ETFE as the catheter material. The coaxial antenna performance was optimized at a slot distance of 6 mm from the antenna tip. The total power dissipation density and hence, the degree of thermal lesion created during the procedure is dependent on slot position of the coaxial antenna.

People who work will face a variety of stressful situations and pressures. Stress experienced by workers can be caused by various factors, generally caused by external factors and internal factors of the individual itself. Existing studies tend to focus on the influence of external factors on stress conditions experienced by workers, such as environment and work situation. Meanwhile, studies focusing on internal factors as a cause of worker stress, are still not widely practiced, particularly with regard to experience patterns and work-related behavior. Measurements used to measure experience patterns and work-related behavior are also newly adapted in some countries, using the AVEM test. Considering benefits from measuring individual experience patterns and work related behavior through the AVEM test, researchers are interested in adapting AVEM tests into Bahasa Indonesia. Respondents in this study were 357 respondents, with various educational and work background. The data were collected at various locations in Yogyakarta Province. Main instrument used in this study is a work-related behavior and experience patterns test known as Arbeitsbezogenes Vehaltens-Und Erlebensmuster (AVEM Test). In addition, this study also used other measurements to be correlated as part of instruments validation, namely Sense of Coherence Scale (SOC), Parental Stress Scale (PSS), and Family Hardiness Index (FHI). Based on results and discussion, it can be concluded that AVEM test in Bahasa Indonesia and among Indonesian produce items on AVEM test is divided into 2 main dimensions, namely Engagement dimension and Resilience dimension. Meanwhile, Emotion dimension that exists as its own dimension on English version of AVEM test goes into Engagement dimension. And referring to the results of reliability estimates, it can be concluded that Indonesia version of AVEM test is reliable for use on Indonesian. In addition, referring to the results of previous analysis, it can be concluded that Indonesia version of AVEM test can be used as a tool to measure experience patterns and work-related behavior among people of Indonesia.

In recent era of digitalization, all fields of science are engaged in using sophisticated technology to deliver fast and straightforward work. In the completion of construction projects we often encounter complex problems. In general, the factors that affect employee productivity are (a) Low motivation levels of employees due to differences in two cultures (b) unresolved conflicts (c) The low level of entrepreneurial spirit of employees in exploiting the opportunities that exist (d) The failure of the company in regulating Human Resources (HR), (e) The absence of leadership characters between two employee cultures (d) The failure of the company to utilize advanced technology currently related to settlement effective and efficient work. Weaknesses in considering labor productivity are caused by productivity problems in very complex projects and the presence of internal and external factors that influence them. In this case, one construction project has two different ethnicities and cultures, namely Minang culture and Sundanese culture, based on field observations. There are several solutions to overcome them, namely (1) Employee Entrepreneurship Productivity, (2) Work Motivation, (3) Leadership, (4) Human Resources and (5) Work Information Technology. The method used is the MANOVA Statistics (Multivariate of Variant analysis) and realized in SEM (Structural equations Modeling). The results obtained are a model that is effective in increasing employee productivity in the construction industry.

This study aimed to improve the quality of blackwater by using a physical model consisting of 2 processes; stratified filters and wetland. The stratified filtration method utilized gravel, charcoal, and sand as the filter materials, meanwhile, the wetland system utilized the Cattail plant (Typha Angustifolia). Blackwater quality improvement was observed at the intervals of 2 days, 4 days and 6 days, and included parameters of pH, temperature, TSS, TDS, BOD and COD. The method of data analysis was Multiple Linear Regression. Generally, the final result showed that the blackwater quality was improved and met the standard of grade IV water quality (water for agricultural purposes). Furthermore, the equation of Regression analysis obtained was, Water Quality (Y) = 4.693 - 0.176 X1 * - 0.294 X2 * + e6 (X1 = sand thickness, X2 = residence time). This means that every 1 cm thickness of the sand layer contributes to the improvement of water quality by 0.176. In addition, each application of 1 day residence time in the wetland tube has the potential to increase the water quality by 0.294 units. Therefore, the use of filter materials and Cattail plants has been proven to be effective for pollutant removal in blackwater.

This paper is devoted to the design & performance analysis of hybrid Micro-Grid power supply system using HOMER software. The hybrid system has been designed with wind turbine generator, diesel generator and solar panel as components of local micro grid supply system. The design aimed at primarily to create an isolated micro grid system used to supply a reliable and cost effective electric power for the rural village under study. The design is done considering the present and future forecasted household AC loads as well as 2 AC pumps presently operating for agricultural irrigation purposes of the rural communities.Most rural villages in Ethiopia are not connected to the already existing electric supply network/grid. The majority of rural village homes which don’t have access to the National electric supply network usually use diesel generator set or car batteries as preferential power sources for meeting their household electric power supply demand as well as to run pumps for agricultural irrigation puropses. These power sources are not cost effective and not reliable from the point of availability of cheap diesel to the rural village to run generator and requirement of repeated charging cycle’s of batteries. Analysis indicates that Hybrid power supply system which uses two or more power sources will give better and reliable power source with high cost effectiveness.

Text summarization is a process of summarize any text or document. There are many summarization tools for English language. There are also a few works for automated Bengali text or document summarization. The tools are seemed not much appropriate from application point of view. Summarization is categorized in two ways: extractive and abstractive approach. Most of the summarizer methods for Bengali text summarization are extractive. Those proposed methods can’t extract whole theme of a text document. Reader can be satisfied about summary if it gives full important information of input document. Our proposed method introduces an enhanced summarization method that can improved the quality of outputs. The proposed method is modeled combining a set mathematical rules and Bengali grammatical rules. This method also solves many problems of extractive summarizer and it also introduces the path of abstractive summarization methods. Although the method has been developed for Bengali language, it is a generic and platform independent approach and can flexible be extended for other languages.

Information Technology audit itself is a combination of various kinds of knowledge, including: Traditional Audit, Management of Information Systems, Accounting Information Systems, Computer Science, and Behavioral Science. Basically, IT Audit can be divided into two categories, namely Application Control and General Control. General control objectives further guarantee the integrity of the data contained in computer systems and at the same time ensure the integrity of the program or application used to process data. Meanwhile, the purpose of controlling the application is intended to ensure that the data is correctly input into the application, processed correctly, and that there are adequate controls on the output produced. In audits of applications, typically, checks on general controls are also carried out given that general controls contribute to the effectiveness of application controls. In practice, the stages in IT audits are not different from audits in general. The planning stage, as an introduction, is absolutely necessary so that the auditor knows the object to be examined properly. In addition, of course, auditors can ensure that qualified resources are already owned, in this case experienced aspects of HR and also references to best practices.

The development of an increasingly complex organization and the demand to always adapt to the organizational environment, resulting in decision-making processes and management also developed. The process is related to information which is important and valuable in an organization today, because accurate and fast information can greatly help the growth and development of an organization. Therefore, the management of information is seen as important for the smooth running of a job and for analyzing the development of the work itself. This requires learning Management Information Systems in creating, distributing and utilizing information to support management activities, especially decision making in public policy. However, unfortunately many organizations want to build their own Management Information Systems, and have provided sufficient funds, but it turns out that these businesses often fail. The causes include inadequate organizational structure, inadequate organizational plans, inadequate human resources, and most importantly, lack of management participation in the form of manager participation in designing systems, controlling system development efforts and motivating all parties involved.

These Wind turbines are media used to convert wind energy into electrical energy. Counter Rotating type Wind Turbine is a type of wind turbine that has a double rotor. This type of wind turbine was developed because it is very suitable for high-speed wind, in this study the length of the blade is 1.5 m. Therefore the counter-rotating type wind turbine is made with full scale and tested with the wind in nature, especially the coastal area so that it can be seen the counter-rotating type wind turbine performance when using the natural wind in Indonesia. This performance is known by measuring the amount of electric power, torque and radial speed of the front and rear rotors based on high wind speeds. In the end, the performance of the wind turbine can be known at wind speeds of more than 5 m / s where the higher the wind speed the greater the front and rear rotor radial speed. This is directly proportional to the electrical power produced and inversely proportional to torque, where the greater the speed of the second radial rotor, the smaller the torque produced. Based on data obtained at wind speeds of 5.01 m / s, the front and rear radial speeds of the motor are 25 rpm, 12 Nm Torque, and 0.0072 Watt electric power respectively. Whereas the wind speed of 8.17 m / s obtained the values of front and rear radial speeds of 428 rpm, the torque and also electric power respectively 0.700934 Nm and 4.7034 watts.
