X-Ray images are the most widely recognized methods for medical imaging accessibility for individuals during the wounds and mishaps. X-rays are most frequent and the oldest form of medical imaging. Yet, the minute fracture identification using the X-Ray image is beyond the realm of imagination,because of the complication of bone organisation and the dissimilarity in visual attributes of fracture upon their location. This is the reason why it it is hard to detect the fractures and furthermore decide the seriousness of the damage. The major challenges of X-Ray imaging are the presence of noise, intensity ambiguity, and overlapping tissues. This creates a hurdle in correct diagnosis and delays treatment. The various rates require the human services experts to analyze countless x-ray images. computerized detection of fractures in X-Ray images can be a huge commitment for helping the doctors in settling on quicker and increasingly precise diagnostic decisions and speeds up the plan for the treatment. This research compares the existing fracture detection techniques.From various fractures, programmed identification is viewed as challenging since they are unique and variable in presentation and their results are quite un predictable.The major challenges for computer-aided fracture detection can be accurate segmentation process, automatic identification of the region of interest (bone fracture), evaluation and suggestive course of action.

Electronic devices and instruments generate heat that can cause serious damage and low efficiency towards its components. The heat that the different electronic elements and components emit can decrease both efficiency and life capacity of the device. And with the increase of use of electronic devices in industries and processes, heat dissipation in electronic devices should be taken into strict consideration. This study aims to develop a cooling system under vapor compression refrigeration system. The prototype fabricated was designed for the cooling system of two Central Processing Units of desktop computer which can be as good equivalent for the electronic devices in industries. Though ventilation was present in the processing units, certain condition such as condition in surroundings can be of great help to improve the device efficiency. This study also aims to analyze the CPU’s efficiency in relation to lowering ventilation temperatures. The vapor compression refrigeration system will be the main device used for lowering and maintaining a suitable temperature inside the CPU casing. The system works like a centralized air-conditioning system wherein the air from the surroundings will be cooled down by the evaporator in the vapor compression refrigeration system. The cooled air will then be delivered to the CPU through the installed air ducting connections. The recording of CPU’s efficiency is provided by the installed software. It also measures the air conditioned parameters and computation of the CPU power consumption. The results from the test and the analysis of the gathered data showed that 165 watts of heat dissipated was removed by the cooling system and the CPU performance index rose up from 424 to 446 with a discharge air temperature of 29.67 oC. Based from the result, the fabricated binary cooling system is efficient enough to increase the performance index of the CPU and absorbing heat dissipated by the device.

Empathy has been referred to as one of the main aspects and the key impact factor of Design Thinking (DT). The DT process allows the outcome to be a technically viable solution, while being a desirable output for the users (consumers of the products) and an economically feasible project. The production in the DT process starts with the user’s desirability to reach pleasurable and better products. A common approach to gain a desirable output is having empathy with the users. The empathy implies understanding the individual's desires (their functional and supra-functional needs). Several techniques have been identified for uncovering the users’ needs and reaching the maximum empathy; albeit it is not achieved straightforwardly. There are lots of products and services in life that are not as delightful, enjoyable and pleasurable as it should be for the end users. The big concern in this context, yet, is to identify the gap in understanding the users’ needs in the empathy approach. In line with this, the present research is an endeavor to identify the issues associated with empathy in the DT process and to recognize the obstacles for deep and real empathy with the end user. This paper majorly revolves around reviewing the Empathy and the DT. Findings acknowledge that misunderstanding is a common phenomenon in the Empathy approach in the DT process and the leading cause for this misunderstanding is attributed to the users’ supra-functional needs. Indeed, it is underscored hereby that misunderstanding the empathy might result in unpleasant senses among the users, as well as leading to producers’ unplanned charges, suggesting that the designers would be urged to minimize misunderstanding in the empathy approach.

The phenomenal speed of corporate development in modern era demands a universal call for action. The role of corporate sustainable practices should be designed to generate value for all stakeholders’, in a manner to ensure positive ethical, social, cultural, economic and most importantly environmental impact. Evolving world order engendered a greater concern for ecology whereas in the race of materialism, sustainable development has just become an illusion. Sympathizing sustainability issues necessitates human to think and appreciate the extended chains of cause and effect relationship of human doings on his future, these doings can be intentional or otherwise. The agenda of corporate sustainable development cannot be fulfilled until the greedy creatures realize the importance of living in harmony with nature. The most ancient known literature in the world had already suggested the sustainable solutions way back in about 1500 and 1000 BCE [3]. Indian mythology since ages is preaching and practicing sustainability in all traits of life for the establishment of a better society. The present paper is an attempt to draw corporate sustainability lessons from Indian mythology literature that projects natural resources as God and also device ways to please the almighty. This paper is an attempt to suggest corporate world to learn sustainability lessons hidden in Indian mythological preaching through rigorous literature content analysis. The ancient Indian literature (Vedas) encompasses several principles of sustainable development. Principles relating to the unavoidability of facing consequences of one’s actions, the interconnectedness of all living beings, the linkage between present and future, the integrity of the human family, the necessity of harmony between humanity and the natural order and many others are equally apt and can guide sustainable corporate growth. The lesson sums up in “Vasudevkutumbakam” (all belongs to one family) that needs to be engrossed in the corporate strategies for a better tomorrow.

Authors: Melati Sari , Riswan
Published: December 2019

Penelitian ini bertujuan untuk memprediksi nilai modulus elastisitas batuan utuh dan modulus deformasi massa batuan. Pemboran inti pada batulempung di kedalaman 35, 42, dan 60 meter serta batubara di kedalaman 164 dan 181 meter telah dilakukan untuk mendapatkan contoh batu berbentuk silinder. Kemudian gaya diukur dan perpindahan titik diamati selama contoh diuji kuat tekan uniaksial. Selanjutnya regangan dan tegangan dihitung untuk membangun kurva perilaku konstitutif. Modulus elastisitas batuan utuh diprediksi dari Modulus Young Rata-rata karena tipe kurva tegangan-regangan contoh batubara dan batulempung yang diuji termasuk fase elastik pendek. Modulus deformasi massa batuan diprediksi dari Modulus Young Sekan yang diukur dari tegangan nol sampai lima puluh persen dari tegangan puncak. Hasil penelitian menunjukan bahwa Modulus Young contoh batubara 0.30 dan 0.44 GigaPascal (GPa), sedangkan contoh batulempung 3.92, 4.14, dan 4.28 GPa. Modulus deformasi massa batuan batubara  diprediksi 0.11 dan 0.35 GPa, sedangkan modulus deformasi massa batuan batulempung diprediksi 2.40, 3.86, dan 4.46 GPa. Dengan demikian dapat dikatakan bahwa batuan sedimen di Formasi Tanjung Kalimantan Selatan memiliki karakteristik modulus deformasi massa batuan yang 20-63% kurang dari modulus elastisitas batuan utuh. Mengingat studi mengenai topik tersebut masih terbatas jumlahnya, data empiris yang didapatkan dari penelitian ini sangat berharga untuk berbagai kepentingan di bidang mekanika batuan. Contoh terapannya yaitu modulus deformasi massa batuan sebagai parameter masukan pada analisis tegangan-regangan di sekitar bukaan tambang bawah tanah menggunakan permodelan numerik, penilaian kondisi tegangan insitu dan distribusi tegangan terinduksi melalui pemantauan pergerakan massa batuan, atau perhitungan energi regangan dari ledakan batuan (rock bursts).

Perlindungan Hak Perempuan dalam Perkembangan Hak Azasi Manusia di Indonesia
Authors: Sumirat Iin Ratna
Published: December 2019

Hak asasi manusia yang dipahami sebagai natural right merupakan suatu kebutuhan dari realitas sosial yang bersifat universal. Berdasarkan sudut pandang ini, sangat wajar sekali apabila hak asasi manusia telah berkembang sebagai suatu tatanan yang semula hanya sebatas negara tertentu saja, sekarang telah mendunia dan merupakan cerminan dari bermacam-macam norma perilaku yang diterima secara khusus oleh sebagian besar negara-negara di dunia. Asumsi inilah sebenarnya yang dijadikan sebagai dasar dari diterimanya pernyataan hak asasi manusia sedunia pada tahun 1948 oleh suatu badan internasional yaitu PBB. Namun harus disadari pula, salah satu masalah pokok yang dihadapi setiap upaya untuk melembagakan ide-ide pemajuan dan perlindungan hak asasi manusia adalah soal penegakan berbagai instrumen hak asasi manusia dalam praktek di negara-negara yang beranekaragam, baik dalam kondisi-kondisi sosial ekonomi dan budayanya maupun dalam tingkat perkembangannya masing-masing. Karena itu, sering muncul perbedaan yang kerap kali diawali dari adanya perbedaan pandangan, baik mengenai universalitas konsep hak asasi manusia itu maupun mengenai relativitas prosedural upaya-upaya untuk mengimplementasikan prinsip-prinsip hak asasi manusia yang universal

Historicizing Race, Ethnicity, and the Crisis of Citizenship in Sudan and South Sudan
Authors: Idris Amir
Published: December 2019

This article critically outlines the discursive construction of racial and ethnic identities in Sudan and South Sudan, arguing its legacy is essential to understand the entanglement of state-formation, nationalism, citizenship, and political violence in both countries. Race and ethnicity
were central to the colonial, nationalist, and postcolonial projects of inventing the "North" and the "South" as self-contained entities, and the politicization of race and ethnicity after independence is largely a product of "Orientalizing" cultural differences through colonial administrative
rules and postcolonial policies.
Correlated Depletion and Dilution of Lithium and Beryllium Revealed by Subgiants in M67
Authors: Boesgaard Ann Merchant , Lum Michael G. , Deliyannis Constantine P.
Published: December 2019

The surface content of lithium (Li) and beryllium (Be) provides insight into the mixing and circulation mechanisms in stellar interiors. The old open cluster, M67, has been well-studied for Li abundances in both main-sequence and evolved stars. The Be abundances give us a probe to a deeper level in stars. We have taken high-resolution spectra with Keck I with HIRES to determine Be abundances along the subgiant branch of M67, where there are dramatic depletions of Li. These subgiants range in mass from 1.26 to 1.32 M
⊙ and have evolved from main-sequence stars that would have occupied the region of the Li–Be dip found in younger clusters. Lithium abundances have been adjusted to the same scale for 103 stars in M67 by Pace et al. The more massive stars—now the coolest and furthest-evolved from the main sequence—show a drop in Li by a factor of 400 across the subgiant branch. Our new Be abundances also show a decline, but by a factor of ∼50. The two elements decline together with Li showing a steeper decline in these subgiants than it does in the Li–Be dip stars. The relative decline in Be abundance compared to Li is remarkably well fit by the models of Sills & Deliyannis, made specifically for the subgiants in M67. Those models include the effects of mixing induced by stellar rotation. These M67 subgiants show the effects of both main-sequence depletion and post-main-sequence dilution of both Li and Be.
On the Sensitivity of Heliosphere Models to the Uncertainty of the Low-energy Charge Exchange Cross-section
Authors: Bzowski M. , Heerikhuisen J.
Published: December 2019

Models play an important role in our understanding of the global structure of the solar wind and its interaction with the interstellar medium. A critical ingredient in many types of models is the charge-exchange collisions between ions and neutrals. Some ambiguity exists in the charge-exchange cross-section for protons and hydrogen atoms, depending on which experimental data is used. The differences are greatest at low energies, and for the plasma-neutral interaction in the outer heliosheath may exceed 50%. In this paper we assess a number of existing data sets and formulae for proton–hydrogen charge exchange. We use a global simulation of the heliosphere to quantify the differences between the currently favored cross-section, and we suggest a formulation that more closely matches the majority of available data. We find that in order to make the resulting two heliospheres the same size, the interstellar proton and hydrogen densities need to be adjusted by 10%–15%, which provides a way to link the uncertainty in the cross-section to the uncertainty in the parameters of the pristine interstellar plasma.

INTRODUCTION: Prohibited substances issue and their abuse have become a scourge for people in Indonesia. This situation creates concern for every level of society since this is very influential to damage and can even eliminate generations at a later time.
AIM: This study aims to determine the characteristics of age, education, psychological and social problems related to substance dependence experienced by individuals with substance disorders who undergo rehabilitation in Medan, Indonesia.
METHODS: This study is a cross-sectional analytic, in which the sample of this study was individuals who underwent rehabilitation in the Rehabilitation Center in Medan City who fulfilled the inclusion and exclusion criteria. A structured interview was carried out with the MINI ICD-10 on part M. disorders related to psychoactive substances. Furthermore, to see the level of dependence, WHO ASSIST questionnaire (The Alcohol, Smoking and Substance Involvement Screening Test) was used.
RESULTS: This study discovered that subjects with age above 21 years were the most dominant of the prohibited substance users group as many as 87 people (69%), Batak tribe with 73 people (57.9%), residence originating from outside the city with 70 people (55.6%), Unmarried with 87 people (70.2%), education level is medium (junior high school) with 117 people (92.9%) and work as many as 77 people (61.1%). The study also found that the most dominant number of prohibited substances users were single users of methamphetamine and a combination of two substances, each of which was 49 people (38.9%). There is no relationship between social factors and patterns of prohibited substance use. Also, the most dominant users of prohibited substances who undergo rehabilitation are those based on family and police (involuntary admission). Finally, as many as 70 people used methamphetamine require intensive intervention.
CONCLUSION: This study shows that social and demographic factors are not related to the pattern of prohibited substance use.

The aim of the research was to investigate the rheological behaviour of hydroxyethyl cellulose gels, which are used in the development of the composition and technology of the medicine with anti-inflammatory activity. The objects of research were hydroxyethyl cellulose gels in the concentration of 1.0%; 1.5%; 2.0%; 2.5% and 3.0%. Investigation of the rheological behavior of HEC gels (structural and mechanical properties) was performed using the Rheolab QC rheometer from Anton Paar (Austria) using the C-CC27 / SS Coaxial Cylinder System. The obtained results showed that excipients influence on the rheological behaviour in the following way: propylene glycol and polyethylene oxide 400 reduce rheoparameters, while PEG 40 hydrogenated castor oil increases these parameters. The further study of the rheological properties in comparison with medicines “Troxerutin” and “Thiotriazolinum” showed that the developed gel fully corresponds to technological and consumer requirements.
