PENDAHULUAN Energi merupakan kebutuhan pada kehidupan manusia. Semakin bertambah jumlah penduduk, maka kebutuhan energi juga meningkat. Sumber energi fossil yang digunakan untuk memenuhi kebutuhan energi semakin lama semakin menipis. Sehingga diperlukan sumber energi alternatif atau peningkatan efisiensi dalam pemanfaatan energi. Panas buang merupakan salah satu sumber energi alternatif. Panas buang adalah panas yang dibangkitkan dari pembakaran bahan bakar atau reaksi kimia yang kemudian dibuang ke lingkungan walaupun masih dapat digunakan [1]. Pemanfaatan panas buang bermanfaat untuk mengurangi polusi, konsumsi energi untuk peralatan bantu (kipas, pompa, dll). Indonesia memiliki mayoritas pembangkit listrik tenaga uap [2]. PLTU memiliki panas buang yang berpotensi untuk dimanfaatkan. Temperatur gas buang pada PLTU yang rata-rata sebesar 150 C mampu dimanfaatkan [3]. Pemanfaatan panas buang salah satunya adalah dengan menggunakan siklus rankine organik. Saat ini, teknologi ORC ( Organic Rankine Cycle ) berkembang semakin pesat, sehingga limbah – limbah panas yang awalnya dibuang begitu saja, sekarang menjadi potensi untuk membangkitkan listrik dengan ORC. Prinsip kerja ORC sama dengan RC (Rankine Cycle) hanya saja berbeda pada fluida kerjanya. ORC dapat memanfaatkan sumber panas dengan temperatur sekitar 80 C, dikarenakan titik didih fluida organik yang rendah. Kelebihan dari siklus ORC adalah mampu bekerja pada temperatur rendah. Pemanfaatan limbah panas ini mampu menghasilkan energi listrik tambahan yang dapat meningkatkan efisiensi, dan meminimalisir panas yang terbuang ke lingkungan serta penghematan bahan bakar[4]. Dengan memanfaatkan gas buang hasil pembakaran pada PLTU, diharapkan hasil perancangan siklus ORC dari paper ini dapat meningkatkan efisiensi dan menghemat bahan bakar dari PLTU. Selain itu, pemilihan fluida kerja organik juga mempengaruhi efisiensi siklus organik, pada paper ini juga dibahas pengaruh dari pemilihan fluida kerja organik terhadap performa siklus rankine organik.
Mixed layer depth variability in the Red Sea

Abstract. For the first time, a monthly climatology of mixed layer depth (MLD) in the Red Sea has been derived based on temperature profiles. The general pattern of MLD variability is clearly visible in the Red Sea, with deep MLDs during winter and shallow MLDs during summer. Transitional MLDs have been found during the spring and fall. The northern end of the Red Sea experienced deeper mixing and a higher MLD associated with the winter cooling of the high-saline surface waters. Further, the region north of 19° N experienced deep mixed layers, regardless of the season. Wind stress plays a major role in the MLD variability of the southern Red Sea, while net heat flux and evaporation are the dominating factors in the central and northern Red Sea regions. Ocean eddies and Tokar Gap winds significantly alter the MLD structure in the Red Sea. The dynamics associated with the Tokar Gap winds leads to a difference of more than 20 m in the average MLD between the north and south of the Tokar axis.
DIGITIZED CHILDREN'S GAMES FROM THE PAST IN FUNCTION OF THE REALIZATION OF THE MATEMATICS CURRICULUM IN PRIMARY EDUCATION

Cultural development of the modern society, scientific technological and technical level today is a challenge for teachers, where they should respect the traditional didactic principles in the implementation of the teaching process, but, in the same time to think how to convert modern trends in skills of 21st century skills that will be appropriate to the content and organization of contemporary teaching. This paper analyzes the curriculum for mathematics First, Second and Third grade for nine years basic education in terms of the possibility of applying their performances within digitized children's games from the past, as future potential founding in learning through games.

Mathematics curriculum springs, based on the main laws of teaching that is significantly affect the overall teaching process in all components of its organization.
On the average number of normals through points of a convex body

In 1944, Santal\'o asked about the average number of normals through a point of a given convex body. Since then, numerous results appeared in the literature about this problem. The aim of this paper is to give a concise summary of these results, with some new, recent developments. We point out connections of this problem to static equilibria of rigid bodies as well as to geometric partial differential equations of surface evolution.

Managing change in complex projects : configuration management , asset information and big data

As we enter an era of ‘big data’, asset information is becoming a deliverable of complex projects. Prior research suggests digital technologies enable rapid, flexible forms of project organizing. This research analyses practices of managing change in Airbus, CERN and Crossrail, through desk-based review, interviews, visits and a cross-case workshop. These organizations deliver complex projects, rely on digital technologies to manage large data-sets; and use configuration management, a systems engineering approach with mid-20th century origins, to establish and maintain integrity. In them, configuration management has become more, rather than less, important. Asset information is structured, with change managed through digital systems, using relatively hierarchical, asynchronous and sequential processes. The paper contributes by uncovering limits to flexibility in complex projects where integrity is important. Challenges of managing change are discussed, considering the evolving nature of configuration management; potential use of analytics on complex projects; and implications for research and practice. © 2015 The Authors.

Spatial and Temporal Features of the Frequency of Cloud Occurrence over China Based on CALIOP

Spatial and temporal distribution of cloud vertical structure are key components of global climate change. The occurrence of clouds over China and its surrounding areas has been calculated based on cloud layer products from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) at 1 km resolution. Results show significant regional differences in the frequency of cloud occurrence. Fewer clouds are found over the Mongolian Plateau and northern Indian Peninsula, with more clouds apparent over tropical seas and southern China. Cloud cover at night is slightly higher than during the day. Single-layer clouds are more common than multilayer clouds in most areas. In most areas, high-level cloud accounts for the largest proportion of single-layer clouds. The occurrence of clouds in summer and autumn is generally greater than in spring and winter. Single-layer clouds over the Mongolian Plateau and northern Indian Peninsula occur less frequently than multilayer clouds, especially in winter. Furthermore, single-layer clouds are common over the eastern part of southwest China all year round. Over parts of the Tibetan Plateau in summer, high clouds account for the largest proportion (>35%) of annual single-layer clouds, as a result of topography and enhanced summer convection.
Sprawl and Urban Growth

Cities can be thought of as the absence of physical space between people and firms. As such, they exist to eliminate transportation costs for goods, people and ideas and transportation technologies dictate urban form. In the 21st century, the dominant form of city living is based on the automobile and this form is sometimes called sprawl. In this essay, we document that sprawl is ubiquitous and that it is continuing to expand. Using a variety of evidence, we argue that sprawl is not the result of explicit government policies or bad urban planning, but rather the inexorable product of car-based living. Sprawl has been associated with significant improvements in quality of living, and the environmental impacts of sprawl have been offset by technological change. Finally, we suggest that the primary social problem associated with sprawl is the fact that some people are left behind because they do not earn enough to afford the cars that this form of living requires.
Vitamin D and Spectrum of Its Roles

Since last few years vitamin D, i.e., calcitriol is gaining popularity for its various nonconventional roles. Vitamin D and its metabolites have their receptors present in various body tissues. Its use in the body is not limited as mere vitamin but now has been extended through many other actions too. Hormones and vitamin D have many similarities. These similarities are based on mainly the mechanism of action. Like hormones vitamin D is subjected to ‘feedback inhibition’ and also have definite ‘target hormone’.

The patient continued this treatment and the symptoms slowly abated with more than 50% recovery on day 4 [Figure 2]. By the time he was discharged on day 7, his symptoms had almost completely resolved. Examination of the throat revealed normal-sized uvula with minimal congestion and no ulceration.
The Contribution of Non-Physical Resources and Strategic Household Decision-making to Environmental and Policy Risks

Physical resources such as land, labour and livestock, and nonphysical resources such as indigenous knowledge and institutions of producers in the grain surplus and deficit regions of the Central Highlands of Ethiopia are examined under situation of environmental and policy risks. Frequency distribution and comparative statistical analysis of the grain-surplus regions suggest that in situations where all producers are subjected to a common source of risk (e.g. rainfall): I) institutional resources become less effective, and ii) combination of land, labour, knowledge and other complementary resources form the basis for adjustment mechanisms and sequential or strategic decisions. On the other hand, when essential resources such as land are government owned and household decisions are shared by the state, local institutions or social networks become an effective means to maintain reproduction of the farm and producers through providing access to or sharing of resources. In the extreme case of environmental degradation (e.g., drought), farmers follow sequential decision-making. This sequence of decision-making begins with minimization of expenditure, selling of resources that are intended to stabilize farm income, selling of resources essential to farming and depletion of household items, and finally evacuation. The ability of such farming system to regenerate, however, greatly depends not only on the availability of physical resources but most importantly by the potential of knowledge and institutions of producers to adjust to environmental changes, and support from governmental or non-governmental sources.
Effects of Azospirillum brasilense on growth and yield compounds of maize grown at nitrogen limiting conditions

This study aimed to evaluate the agronomic performance of different doses of Azospirillum brasilense in peat formulation on maize crop grown under limited N fertilization, using a completely randomized design with four replicates. The treatments tested consisted of absence of N fertilizer, the full N recommendation and a combination of the half of recommended N associated with the inoculation of three doses of A. brasilense in peat formulation (100 g, 150 g or 200 g per 25 kg of seeds). The following variables were evaluated: insertion height of the first ear height, number of kernel per row, number of row per ear, shoot dry biomass, root dry biomass, chlorophyll content, thousand seed weight, grain N content, shoot N content and grain yield. Half the dose of N fertilizer combined with 150 g per 25 kg of seeds of A. brasilense in peat formulation provided significantly superior results in agronomic performance of maize, particularly regarding grain yield, thousand seed weight and dry biomass of both shoot and root.
A New Approach and Analysis of Modeling the Human Body in RFID-Enabled Body-Centric Wireless Systems

Body-centric wireless systems demand wearable sensor and tag antennas that have robust impedance matching and provide enough gain for a reliable wireless communication link. In this paper, we discuss a novel and practical technique for the modeling of the human body in UHF RFID body-centric wireless systems. What makes this technique different is that we base the human model on measured far-field response from a reference tag attached to the human body. Hereby, the human body model accounts for the encountered human body effects on the tag performance. The on-body measurements are fast, which allows establishing a catalog of human body models for different tag locations and human subjects. Such catalog would provide a ready simulation model for a wide range of wireless body-centric applications in order to initiate a functional design. Our results demonstrate that the suggested modeling technique can be used in the design and optimization of wearable antennas for different real-case body-centric scenarios.
Hatching behaviour of the rice cyst nematodes Heterodera sacchari and H. oryzicola in relation to age of host plant

Hatching of the rice cyst nematodes, Heterodera sacchari and H. oryzicola, has been examined in rice root diffusate, banana root diffusa te, soi! leachate and distilled water using cysts which had been coUected from rice plants at five successive monthly intervals. The rwo species have markedly different hatching behaviours. Irrespective of the age of the host plant producing cysts, H. oryzicola is dependent on root cliffusates to induce substantial hatch. The dependence of H. sacchari on diffusates is Jess easily defined; it is only with cysts from the last rwo extractions that a small proportion of eggs were dependent on root diffusates for hatch and the total percentage hatch from these cysts was considerably less than from cYStS coUected from younger plants. The hatching behaviour of the rwo species are discussed in the context of their contrasting strategies for survival in the absence of a host crop.
THE MEDIATING ROLE OF STRATEGY ON SMALL FIRM PERFORMANCE

Small firms face unique challenges in crafting strategies that best utilize their resource bases. Combinations of resources and strategies lead to firm performance. Current evidence in the entrepreneurship literature shows that firm performance is a function of the contingent effects of strategy and external factors, however the consistency between firm strategy and resources is less well studied. Based on the contention that the quality of a firm’s strategy cannot be judged independently of the resources upon which it is based (Barney & Zajac, 1994), we examine the relationship between firm resources, strategies, and performance in a cross-section of 284 small firms. Using a structural equation analysis, we examine the mediating role of firm strategies as they lead to firm performance in small firms that are operating in less glamorous industries. Our findings demonstrate that neither resources nor strategies alone explain firm performance, but instead that small firms fit their strategies to their resource profiles. Human and organizational resources in combination with a strategy of quality/customer service enhance firm performance. Author
The Role of Regime Type in Counterinsurgency Outbreaks and Outcomes

What effect, if any, does democracy have on outcomes of counterinsurgency wars? Previous studies have provided inconclusive answers mainly because of the challenges involved in testing the question empirically: First, insurgencies are not accidental and the anticipated outcomes also affect whether they break out in the first place. Second, regimes are non-random and their determinants can also affect insurgency incidence and its outcomes. Moreover, different aspects of democracy can have opposite effects on the government's chances of winning. I address these challenges by conducting a critical test to distinguish between different causal mechanisms. I find that domestic institutions that are associated with public goods provision make insurgency onsets less likely. I also show that once we control for this selection effect, domestic political institutions do not influence insurgency outcomes.
The interrelationship of proficiency in ~ secpnd languageand understanding of scientific concepts

There is debate as to whether poor performance in academic tasks by English Second Language students is due to language difficulties or to conceptual difficulties. In this paper I suggest that these two aspects are very closely interrelated. Evidence from written tasks completed by students on a university bridging year suggests that students' proficiency in written English is dependent on their understanding of the task and the scientific concepts relevant to that task.
Using Diversity for Classifier Ensemble Pruning: An Empirical Investigation

The concept of `diversity' has been one of the main open issues in the field of multiple classifier systems. In this paper we address a facet of diversity related to its effectiveness for ensemble construction, namely, explicitly using diversity measures for ensemble construction techniques based on the kind of overproduce and choose strategy known as ensemble pruning. Such a strategy consists of selecting the (hopefully) more accurate subset of classifiers out of an original, larger ensemble. Whereas several existing pruning methods use some combination of individual classifiers' accuracy and diversity, it is still unclear whether such an evaluation function is better than the bare estimate of ensemble accuracy. We empirically investigate this issue by comparing two evaluation functions in the context of ensemble pruning: the estimate of ensemble accuracy, and its linear combination with several well-known diversity measures. This can also be viewed as using diversity as a regularizer, as suggested by some authors. To this aim we use a pruning method based on forward selection, since it allows a direct comparison between different evaluation functions. Experiments on thirty-seven benchmark data sets, four diversity measures and three base classifiers provide evidence that using diversity measures for ensemble pruning can be advantageous over using only ensemble accuracy, and that diversity measures can act as regularizers in this context.
Association of the rs2279744 Promoter Polymorphism in the MDM2 Gene with Breast Cancer in a Mexican Population

Introduction: The MDM2 gene plays an important role as negative regulator of the p53 tumor suppressor. Data on polymorphisms in the MDM2 gene have revealed associations with cancer, particularly for the rs2279744 promoter polymorphism (309 T > G), which attenuates the P53 pathway and promotes tumorigenesis in the mammary gland. Material and Methods: We examined the role of the MDM2 309 T > G polymorphism through a comparison of the genotypes of 408 healthy Mexican women with those of 529 Mexican women with breast cancer (BC). Results: The genotype frequencies of the MDM2 309 T > G polymorphism in controls and BC patients were 25% and 23% for T/T (wild type), 50% in BC and controls for T/G, and 25 and 27% for G/G (polymorphic type), respectively. The obtained odds ratio (OR) was 1.07, with a 95% confidence interval (95% CI) of 0.79-1.45, p = 0.64 for the T/GG/ G genotypes. The association was evident when the distributions of the G/G genotypes in patients exhibiting the following characteristics were compared: breastfeeding >6 months (OR 2.1, 95% CI 1.3-3.4, p = 0.002), obesity (OR 1.8, 95% CI 1.2-2.7, p = 0.003) and high GGT levels (OR 1.7, 95% CI 1.1-2.5, p = 0.012). The genotype G/G of the MDM2 309 T > G. Conclusions: The MDM2 309 T > G polymorphism was associated with BC susceptibility, particularity in breastfeeding, obesity and high GGT levels in the analyzed Mexican population.

Journal Writing and the Question of Transfer of Skills to Other Types of Writing('National Policy' for Foreign Language Education : Searching for the Ideal)

This report looks at the effect of journal feedback and the possible transfer of skills from journal writing to in-class compositions. Although no statistically significant justification for belief in a positive transfer-of-skills effect was found, only the meaning-focused feedback group was found to have made a steady increase in the number of error-free clauses over time, in both their journal entries and in their in-class writing samples. 本稿は英語日記に対するのフィードバックの効果、ならびに英語で日記をつけることで 得たスキルが、授業の中でのライテイングへ転化されるかどうかを検証する。 スキルの 有効な転化がある、という見解を裏付ける統計的に有意な確証は得られなかったが、意味 に中心をおいたフィードバックを受けたグループについては、誤りのない文節の数の着実 な増加が、日記への書き込みにも、授業の中でのライテイングのサンプルにもみとめられ た。
