Authors: Adini Muhammad Hifdzi , Purba Harja Santana , Sukmawati R. Ati
Published: April 2019

Abstract. In general, the learning process is implemented by using face-to-face model, meaning that participants and teachers are in one place and one time. With this model, usually communication between participants and teachers can be easily implemented. But there are some obstacles that may be faced, such as the lack of time to discuss and the limited space that can be used. To overcome these problems, a model is needed that provides a medium for meeting participants and teachers without limited space and time. The model is known as blended learning. The blended learning model allows participants and teachers to discuss, share material and practice questions on a virtual classroom. The research undertaken is to develop a blended learning model using an analysis of the blended learning implementation framework and the use of Content Management System (CMS) WordPress technology. With this model is expected to be an additional media used to support teaching and learning process. Keywords: blended learning; virtual class; wordpress. Abstrak. Secara umum, proses pembelajaran dilaksanakan dengan menggunakan model tatap muka, artinya peserta dan guru berada di satu tempat dan satu waktu. Dengan model ini, biasanya komunikasi antar peserta dan guru dapat dengan mudah diimplementasikan. Tapi ada beberapa kendala yang mungkin dihadapi, seperti kurangnya waktu untuk berdiskusi dan keterbatasan ruang yang bisa digunakan. Untuk mengatasi masalah ini, diperlukan sebuah model yang menyediakan media untuk bertemu peserta dan guru tanpa ruang dan waktu yang terbatas. Modelnya dikenal sebagai blended learning. Model blended learning memungkinkan peserta dan guru mendiskusikan, berbagi materi dan mempraktikkan pertanyaan di kelas virtual. Penelitian yang dilakukan adalah mengembangkan model blended learning menggunakan analisis kerangka kerja implementasi blended dan penggunaan teknologi WordPress Content Management System (CMS). Dengan model ini diharapkan bisa menjadi media tambahan yang digunakan untuk menunjang proses belajar mengajar. Kata kunci: blended learning; kelas virtual; wordpress.

Natural Cities Generated from All Building Locations in America
Authors: Jiang Bin
Published: April 2019

Authorities define cities – or human settlements in general – through imposing top-down rules in terms of whether buildings belong to cities. Emerging geospatial big data makes it possible to define cities from the bottom up, i.e., buildings determine themselves whether they belong to a city based on the notion of natural cities that is defined based on head/tail breaks, a classification and visualization tool for data with a heavy-tailed distribution. In this paper, we used 125 million building locations – all building footprints of America (mainland) or their centroids more precisely – to derive 2.1 million natural cities in the country (http://lifegis.hig.se/uscities/). These natural cities – in contrast to government defined city boundaries – constitute a valuable data source for city-related research.
Structuredness as a Measure of the Complexity of the Structure and the Role of Post-Dissipative Structures and Ratchet Processes in Evolution
Authors: Mikhailovsky George
Published: April 2019

As shown earlier, the algorithmic complexity, like Shannon information and Boltzmann entropy, tends to increase in accordance with the general law of complification. However, the algorithmic complexity of most material systems does not reach its maximum, i.e. chaotic state, due to the various laws of nature that create certain structures. The complexity of such structures is very different from the algorithmic complexity, and we intuitively feel that its maximal value should be somewhere between order and chaos. I propose a formula for calculation such structural complexity, which can be called - structuredness. The structuredness of any material system is determined by structures of three main types: stable, dissipative, and post-dissipative. The latter are defined as stable structures created by dissipative ones, directly or indirectly. Post-dissipative structures, as well as stable, can exist for an unlimited time, but at the micro level only, without energy influx. The appearance of such structures leads to the “ratchet” process, which determines the structuregenesis in non-living and, especially, in living systems. This process allows systems with post-dissipative structures to develop in the direction of maximum structuring due to the gradual accumulation of these structures, even when such structuring contradicts the general law of complification.

Cardiovascular diseases are one of the leading causes of death and generally originated as coronary artery disease (CAD) or hypertension. In later stages, many patients develop left ventricle dysfunction (LVD). Left ventricular (LV) function is the most prognostic factor in CAD patients. LVD is a complex multifactorial condition in which the left ventricle of the heart becomes functionally impaired. Various genetic studies have correlated LVD with dilated cardiomyopathy (DCM). In recent years, enormous progress have been made in identifying the genetic causes of cardiac diseases, which has further led to a greater understanding of molecular mechanisms underlying each disease. This progress has increased the probability of establishing a specific genetic diagnosis, and thus providing new opportunities for practitioners, patients, and families to utilize this genetic information. A large number of mutations in sarcomeric genes have been discovered in cardiomyopathies. In this review, we will explore the role of the sarcomeric gene in LVD in CAD patients, which is a major cause of cardiac failure and results in heart failure.
Scaling Up the Production and Commercialization of Tamarind Fruit in Kenya: The Missing Value Chain Links
Authors: Simon Omondi
Published: April 2019

There is limited information on Tamarind production, trade and value added products in Kenya.   Of late, there is growing interest in the domestic and export markets due to its multiple uses. The objective of this paper is to review existing literature to identify the missing value chain links which may help catalyse the scaling up of production and commercialization of Tamarind. Selected literature and interviews with traders and extension staff in the Coastal Counties were used to collect information for this study. Tamarind fruits are mainly collected in the wild in semi-arid areas of the country and marketed through informal channels. Mombasa is the terminal market for tamarind from Kenya and Uganda, from where domestic consumers and exporters obtain their supplies. Globally, virtually every part of tamarind tree (pulp, seed, leaves, flowers, bark and roots) has either nutritional, industrial or medicinal value. Tamarind fruit contains substantial levels of carbohydrates, proteins, vitamins, minerals and essential amino acids making it potentially useful in addressing wide spread malnutrition. Its anti-oxidant, anti-inflammatory, anti-microbial, anti-fungal and anti-diabetic properties gives tamarind wider application in conventional and traditional medicine. The findings suggest that scaling up the production and commercialization of tamarind in the country requires both public and private sector investment. The structure of this partnership should consist of the following value chain links: An efficient Seed / seedling system as a source of planting materials; production hubs by farmer associations, government institutions and private farms; aggregation centres for assurance of volumes and quality; processing, value addition and product diversification; an efficient distribution systems of wholesalers and retailers, particularly supermarkets; exporters and consumers. The agenda for further research should include breeding and availing early maturing cultivars demanded by the export market, quality management andvalue addition technologies.
Wet-dry Cycling Delays the Gelation of Hyperbranched Polyesters: Implications to the Origin of Life
Authors: Mamajanov Irena
Published: April 2019

In extant biology, biopolymers perform multiple crucial functions. The biopolymers are synthesized by enzyme-controlled biosystems that would not have been available at the earliest stages of chemical evolution and consist of correctly sequenced and/or linked monomers. Some of the abiotic “messy” polymers approximate some functions of biopolymers. Condensation polymers are an attractive search target for abiotic functional polymers since principal polymers of life are produced by condensation and since condensation allows for the accurate construction of high polymers. Herein the formation of hyperbranched polyesters that have been previously used in the construction of enzyme-like catalytic complexes is explored. The experimental setup compares between the branched polyesters prepared under mild continuous heating and the wet-dry cycle conditions. The results reveal that period wetting during which partial hydrolysis of the polyester occurs, helps control the chain growth and retards the gel transition. It is significant to the origin of life studies that environmental, prebiotically plausible conditions could achieve such control without enzymes or a skilled chemist. As expected in marginally controlled systems, the identification of each component of the heterogeneous system has proved challenging, but it is not crucial for drawing the conclusions.
Applying Philosophy to Refereeing and Umpiring Technology
Authors: Collins Harry
Published: April 2019

This paper draws an earlier book (with Evans and Higgins) entitled Bad Call: Technology’s Attack on Referees and Umpires and How to Fix It (hereafter Bad Call) and its various precursor papers. These show why it is that current match officiating aids are unable to provide the kind of accuracy that is often claimed for them and that sports aficianados have been led to expect from them. Accuracy is improving all the time but the notion of perfect accuracy is a myth because, for example, lines drawn on sports fields and the edges of balls are not perfectly defined. The devices meant to report the exact position of a ball – for instance ‘in’ or ‘out’ at tennis – work with the mathematically perfect world of virtual reality, not the actuality of an imperfect physical world. Even if ball-trackers could overcome the sort of inaccuracies related to fast ball speeds and slow camera frame-rates the goal of complete accuracy will always be beyond reach. Here it is suggested that the purpose of technological aids to umpires and referees be looked at in a new way that takes the viewers into account.
