This paper discusses the complex relationships between the formation of communal brand geography and economic growth. We are investigating ways in which communal brand geography may be the issue directly to the growth, controlling for economic policies and institutions, as well as the effect of geography on the policy choices and institutions. We find that the location and climate have a major impact on the level of revenue and earnings growth. In addition, geography seems to be a factor in the choice of the formation of communal brand itself. When we identify a geographic area that is not conducive to the growth of the modern economy, we find that much of this area has a density and fast population increase. In addition, much of the revenue increase may take place this upcoming community in this area are not benefitting geographically.

Accreditation is a quality assurance and improvement process that determines whether the set educational objectives meet a general standard of quality. It is an endorsement of how good these expectations are satisfied. Outcome based education system (OBE) emphasizes on quantifying what the students are capable of doing. Program outcomes represent the knowledge, skills and attitudes the students should have at the end of program. Program outcomes can be directly measured through Course Outcomes which are broad statements indicating knowledge and skills the student acquires at the end of a course. The outcome based education model is based on defining various parameters called as Graduates Attributes. Assessment of learning outcomes is one of the key aspects of OBE model. This is done through assessment of course outcomes for each course in a program. In this paper, an approach based on assigning two step weights for assessment of course outcomes is presented. The method proposed provides the result of course outcome attainment. The results are obtained through a program in MS Excel.

In 2010 to 2016, Indonesia imported white crystal sugar (WCS) to fulfill the household consumption. The objectives of this research are to: 1) examine the possibility of achieving self-sufficiency of WCS without the policy of National Sugar Industry Revitalization (NSIR), 2) analyze the impact of NSIR policy on the achievement of national sugar self-sufficiency, and 3) formulate an alternative policy of WCS production. This study used primary and secondary data. The primary data collection was conducted by interviewing the respondents, including sugar cane farmers, representatives from the Center for Sugar Research and Development (P3GI), National Plantation Company (PTPN) XI, Indonesian Ministry of Agriculture, as well as from the sugar factory representatives. Secondary data were taken from related institutions, i.e., Indonesiaís Central Bureau of Statistics (BPS), sugar factory, and Indonesian Ministry of Agriculture. The modeling simulation is conducted using Powersim studio software to analyze national sugar industry from 2010 to 2025. The analysis period is based on the implementation year of the NSIR policy. The model behavior in actual condition indicates that national self-sufficiency is not achieved without the implementation of NSIR policy as indicated by the negative supply of WCS during the simulation period. Therefore, a joint NSIR policy is required to achieve national self-sufficiency. Applying 8 (eight) policy scenarios, results of the research show that: 1) in partial, the scenario of NSIR policy fails to support the achievement of national sugar self-sufficiency, 2) policy simulation of scenario 5 (demand side), i.e., the reduction of WCS consumption can make Indonesia achieves national sugar self-sufficiency, and 3) simultaneous NSIR policy on scenario 4 (supply side), i.e., the land expansion, productivity, and sugar yield, can make Indonesia achieves national sugar self-sufficiency.

Along with the rapid development of Social Networking Sites (SNS), social media, recently, has become a lifestyle for many people around the world, including in Indonesia. The data in January 2018 showed that in Indonesia out of 132.7 million internet users, almost all (131 million), or up 23% from the data in 2017, were Facebook users with the dominance of 18-24 years old, 35% of whom were the highest active users. The rapid growth of Facebook users annually in Indonesia, especially in the age of students and college students, encourages researchers to conduct many empirical studies of Facebook use among students. There is a tendency for using Facebook continuously to create FAD effects (Facebook Addiction Disorder) among students and can affect the spirit of learning. This study also discusses what is the motivation for using Facebook and seeing the potential for FAD to occur. In this study, an online survey over 375 respondents from several students in Labuhanbatu District was conducted. To explore respondents' motives in using Facebook, respondents were given questions that were divided into the following five motives: social interaction, leisure time, entertainment, friends, and communication. While to look for potential addiction, respondents were given questions using the Bergen Facebook Addiction (BFAD) scale. In getting a connection between the motives for using Facebook and Facebook Addiction, the data was tested by analysis of variants (ANOVA) and partial tests using SPSS software. The results obtained were 65.8% of participants were at a moderate level, while 20.3% were at a low level, and only 13.9% of participants were at a high level. While the most significant motive affecting respondents in using Facebook is the motive to fill the time and motives for communicating.

Environment change is amongst the greatest ecological issues that individuals have confronted, and also the key trigger driving it is the reliance on fossil powers. Burning up fossil fuel, oil as well as other fossil energy sources is the major means through which many of us generate electrical power, it also contributes to major levels of air-borne pollutants within our atmosphere and water. By making use of green energy resources, we likewise decrease our reliance on fossil energy resource gasoline and also oil supplies, so that we are able to prevent the growing cost of energy expenses and enhance our power stability. A microbial fuel cell (MFC) is a bio-electrochemical system that makes use of the ability of respiring microorganisms to transform natural and organic substrates straight into electrical power. At its key, the MFC is a fuel cell, which in turn converts chemical substance vitality into energy employing oxidation lowering responses. This paper presents focus on the global development overview of MFC.

Since mining started in 2008, Lumwana (Malundwe) Open Pit has experienced slope failures in the saprolite formation in the upper stacks of the pitís slope, during rain seasons. Comprehensive integrated studies have been performed to investigate parameters controlling the stability of the upper stack of Lumwana (Malundwe) open pit due to rainfall pattern. The study results reveal that the saprolite soilsí matric suction increases with the decrease in rainwater content in the saprolite soil, leading to an increase in shear strength of the slope for the upper stacks. Once shear strength is sufficiently increased , the saprolite soil slope become sufficiently stable in dry season. During rain season, the negative pore pressure tend to reduce towards zero and even become positive with rising water table. Such a change in pore water pressure causes a decrease in the shear strength. Once the shear strength is sufficiently decreased , the upper slope becomes instable that slope failure may occur. Generally, the events of rainfall gives an impact on the degradations of the safety factor of upper stack of Lumwana (Malundwe) open pit.

A song is one of the media used to express emotions or convey messages. Aside of music and rhythm, the lyrics also plays an important tole to convey these messages. However, song lyrics are usually written in the form of rigid text with a monotonous form, so that it only served as a pointer without any expression and emotional value. This article will discuss the way the text of the lyrics can help express the emotion and message within the song by using lyrical typography. This article discussed an experimental research method done with the approach of typography, semantics, and illustration to create a visual experience in writing the song lyrics. The result compiles the illustrations from the said experiments and show that lyrical typography can help express the song so that the audience can see the visualization created and gain a new way to experience the song through the use of this lyrical typography.

Oxidation is a common reaction that takes place during preparation of different foods. It takes place through transferring electrons from a chemical compound to other/s. Researchers believe that oxidation has negative impact on human health. Moreover, existence of anti-oxidants in any food means existence of substances, which can delay or stop the oxidation process, as oxidation not only affects health but also deteriorates the natural flavor of any food. Some anti-oxidants are natural but others are synthetic. Natural anti-oxidants, commonly denoted as NAOs, are preferential choice of doctors and customers. They exist in multiple food sources including vegetables, fruits, and other plant-based and animal-based diets. In this article, we have described only those oxidants, which can be obtained through natural sources

Farmers in the Northern Region of Ghana are mostly smallholder farmers. They are continuously confronted with erratic rainfall and land degradation as a result of poor agronomic practices. Soil and Water Conservation (SWC) methods are interventions that can be put in place to limit soil loss and sustain soil moisture in areas where there is inadequate moisture and the risk of losing the valuable topsoil. In the 2014 cropping season, an on-farm experiment was conducted in the Region to assess the effect of SWC methods [Contour Farming (CF), Half Moon (HM), Contour Ridges (CR) and Flat Land (FL)] on soil moisture content at the root zone, growth components and yield of maize. There was a significant effect of the SWC methods on soil moisture at the root zone of maize at a probability (P) value of 0.00181. The CF retained the most soil moisture at the root zone with an average volumetric soil moisture of 18.4%. This was followed in decreasing order by CR (18.1%), HM (17.8%) and the FL (16.8%). The SWC methods significantly affected maize height (P = 0.0112), stem (P = 0.0174), root biomass (P = 0.035) and grain yield (P = 0.00578). Considering the higher soil moisture retention and yield under CF, it is recommended as the best option among the studied methods for SWC in Northern Region of Ghana.

Bad governments in Nigeria and most Third World countries are resulting in poverty of the people as a result, negatively impacting their built environment and especially, architecture. A lot of poor people are reverting to the use of prehistoric building materials including, clay/laterite soil (in mud buildings), plant leaves and recycled products, used hundred years ago. This paper aims at, identifying how bad governments promoted poverty in both their urban and rural communities and proffered solutions to the negative impacts of poverty in their architecture. It adopted qualitative research method that embraced information from secondary data sources. The invention of bottled water in Nigeria resulted in abundance of empty plastic containers (wastes) in the communities with architectural values. They are used by the poor in building their houses and fences. The governmentsí current bad and unsustainable policies are reversing the assumed improved standards of living and lifestyles of the poor, to nomadic living and pushing the poor into impoverished lifestyles. This paper recommends for the players to start discussing todayís environment for tomorrowís generation, develop and implement documents that would guide and promote development and growth plan of the communities leading to unprecedented indoor-outdoor standardized growth, human and economic empowerment.

Clarithromycin resistance is one of the main predictors of eradication treatment failure in Helicobacter pylori (H. pylori) infections. Clarithromycin-based regimens were commonly used as a first-line therapy for H. pylori-positive patients. Lately, cure rates of H. pylori infection are decreasing to as low as 60% and are inversely correlated with antibiotic resistance rates that have crossed the 15-20% threshold. Monitoring of antibiotic susceptibility of H. pylori can be achieved through molecular methods; which stand out as an attractive alternative to conventional culture-based methods. The 23S rRNA Real-time PCR has several advantages in detection of H. pylori resistance to antibiotics; such as short working time, a high specificity up to 100% and low risk of contamination. This study aimed to detect clarithromycin resistance and genetic pattern of H. pylori in a group of 50 patients suffering from symptoms suggestive of gastrointestinal diseases. Gastric biopsy specimens were taken by endoscopy at the Gastroenterology Department of Alexandria Main University Hospital. Genotyping of H. pylori strains using multiplex PCR to detect CagA and VacA genes and detection of point mutations conferring clarithromycin resistance using a 23 S rRNA real time PCR was carried out. The majority (98%) of H. pylori strains detected in patients were CagA positive while only 28/50 (56%) were VacA positive. Most of the strains (67.86%) expressed the s2 (non toxigenic) allele and the most common genotype was VacA s2m1; expressed by 39.3% of strains. All H. pylori strains of the control group were sensitive to clarithromycin while resistance was detected in 26% of strains recovered from cases. The majority (77%) of point mutations responsible for resistance to clarithromycin were due to A-G transition at position 2143 while only 23% of which were due to A-C transition at position 2142.

With respect to the importance of the development of entrepreneurship and employment in renewable energies technologies, the present research investigated the obstacles of developing entrepreneurship in renewable energies in Iran. The methodology utilized in this paper involved two complementary methods: 1) a series of semi-structured interviews with 15 renewable energy entrepreneurs and 2) a questionnaire survey. The participants were identified via SATBA. Through the use of a simple random sampling method, 97 people were selected as sample. The results indicated that the most important barrier of entrepreneurship development in the field of renewable energies was inadequate access to institutional finance, inadequate government or policy support and the power of incumbents which were into the first, second and third ranks, respectively. According to the findings, sociocultural and individual barriers explain about 30% of the obstacles entrepreneurs are faced with, that have been neglected in previous studies. Entrepreneurship in the field of renewable energies is considered to be one of the most exclusive solutions for unemployment. In order to solve the problems faced by renewable energies entrepreneurs, the barriers which exist in the way of these activities should be identified and removed. Therefore, this study will take a useful upward step in order to identify these barriers and, eventually, provide the best functional suggestions.
