The possible rate of transition to lower-carbon housing
Authors: Lloyd P
Published: January 2017

Two of the challenges facing any transition to a lower-carbon economy in the building sector are the questions of how rapidly the existing low-efficiency stock of domestic housing can be replaced with more efficient housing, and how efficient the new housing stock can be made. This paper therefore develops a model for the replacement of the global housing stock as it ages, and considers what the demand for new housing stock is likely to be. One driver will clearly be the increasing population. Another will be economic growth, which has the counterintuitive effect of reducing the average occupancy of homes as nations develop economically. This not only accelerates the underlying rate of increase in new housing, forced by the increasing global population, but also offers opportunities for higher-value, more energy-efficient homes. Moreover, economic development is usually associated with greater levels of urbanisation, which allows greater use of multi-dwelling buildings with associated improved efficiency potential. Nevertheless, the lifetime of most homes is inherently long in comparison with the apparent urgency of reducing energy demand, and thus lower carbon emissions. It is concluded that, perse, more efficient housing is unlikely to play a significant part in the transition to a lower-carbon world over the next 35 years until 2050.

Background: Adolescence period is very crucial in the life of an individual, when major physical, psychological and behavioral changes take place. Tobacco and areca nut use among school going adolescent is becoming a major public health problem. The aim was to determine the prevalence and pattern of smokeless tobacco and betel nut use among school going adolescents.Methods: The study was a cross sectional study. After taking the permission of principal of Government high school and consent of the parents of adolescents, 546 adolescents were interviewed during February-March 2016. A self-administered questionnaire was used for data collection. Thus collected data was analyzed using SPSS 17 (Trial Version). Results: Age of the study students (total 546) ranged from 10-19 years. (Mean age=14.60 ± 2.84 years). Out of 546 children 166 (30.4%) children had addiction. Prevalence of any type of addiction in girls and boys was 13.4% and 17.0% respectively. Tobacco prevalence was 12.3% and betel nut prevalence was 18.1%. Type of addiction and its association with gender was highly significant. All children addicted to tobacco using chewing form (gutkha) of tobacco. The mean age group of children who consume tobacco and betel nut was 16.14±1.33 years and 16.13±1.51 years respectively. Most common reasons among adolescents for starting addiction of tobacco and betel nut was to look mature (88.0%) followed by to look good (73.5%) and to refresh breathe (56.0%).Conclusions: High prevalence of tobacco and betel nut use among adolescents needs attention of parents, teachers and health officials.
Internal normalization of nascent RNA sequencing experiments to identify age-related changes of the mouse liver transcriptome
Authors: Fonseca Costa Sara S , Ripperger Jürgen A
Published: January 2017

We are interested to detect age-related transcriptional changes in the mouse liver as model system. However, such transcriptional changes are difficult to detect against the transcriptional noise increasing with age. Here, we investigated a relative strategy to improve the sensitivity of RNA-sequencing experiments. An equal amount of nuclei from rat and mouse liver was mixed, and subsequently nascent RNA (nasRNA) extracted. For normalization purposes, the rat sample was the same, while we used triplicate samples from 3- and 15-month-old mice. The reads obtained by Illumina massive-parallel sequencing were separated, and for each gene was calculated the ratio of mouse nasRNA to rat nasRNA. As such, we could identify age-related changes of the liver transcriptome that we were not able to detect previously.
Histone Code and Higher-Order Chromatin Folding: A Hypothesis
Authors: Prakash Kirti , Fournier David
Published: January 2017

Histone modifications alone or in combination are thought to modulate chromatin structure and function; a concept termed histone code. By combining evidence from several studies, we investigated if the histone code can play a role in higher-order folding of chromatin. Firstly using genomic data, we analyzed associations between histone modifications at the nucleosome level. We could dissect the composition of individual nucleosomes into five predicted clusters of histone modifications. Secondly, by assembling the raw reads of histone modifications at various length scales, we noticed that the histone mark relationships that exist at nucleosome level tend to be maintained at the higher orders of chromatin folding. Recently, a high-resolution imaging study showed that histone marks belonging to three of the five predicted clusters show structurally distinct and anti-correlated chromatin domains at the level of chromosomes. This made us think that the histone code can have a significant impact in the overall compaction of DNA: at the level of nucleosomes, at the level of genes, and finally at the level of chromosomes. As a result, in this article, we put forward a theory where the histone code drives not only the functionality but also the higher-order folding and compaction of chromatin.

Published: January 2017

Models of Biological Regulatory Networks are generally based on prior knowledge, either derived from literature and/or the manual analysis of biological observations. With the development of high-throughput data, there is a growing need for methods that automatically generate admissible models. To have a better understanding of the dynamical phenomena at stake in the influences between biological components, it would be necessary to include delayed influences in the model. The main purpose of this work is to have a resulting network as consistent as possible with the observed datasets regarding the conflicts and the simultaneity between transitions. The originality of our work is threefold: (i) the identification the sign of the interactions, (ii) the direct integration of quantitative time delays in the learning approach and (iii) the identification of the qualitative discrete levels that lead to the systems dynamics.In this work the precision of our automatic approach is discussed by applying it on dynamical biological models coming from the DREAM4 Challenge datasets.
Mathematical modelling of promoter occupancies in MYC-dependent gene regulation
Authors: Benary Uwe , Wolf Elmar , Wolf Jana
Published: January 2017

The human MYC proto-oncogene protein (MYC) is a transcription factor that plays a major role in the regulation of cell proliferation. Deregulation of MYC expression is often found in cancer. In the last years, several hypotheses have been proposed to explain cell type specific MYC target gene expression patterns despite genome wide DNA binding of MYC. In a recent publication, a mathematical modelling approach in combination with experimental data demonstrated that differences in MYC-DNA-binding affinity are sufficient to explain distinct promoter occupancies and allow stratification of distinct MYC-regulated biological processes at different MYC concentrations. Here, we extend the analysis of the published mathematical model of DNA-binding behaviour of MYC to demonstrate that the insights gained in the investigation of the human osteosarcoma cell line U2OS can be generalized to other human cell types.

The discussion in this paper concentrates on Tradition Basasuluh contained in Banjar Tribe. In this tradition, there are some steps being taken by men that if the review of the concept of Sayyid Khitbah Sabiq have conformity and non-conformity, so need assessment and description of the implementation of Tradition Basasuluh Banjar tribe in terms of the concept of Sayyid Khitbah Sabiq. This research is an empirical study with a qualitative descriptive approach, and analyzed using the concept of Sayyid Khitbah Sabiq. The results of the analysis concluded that men should do Bacarian Tatuha Kampung, Bapara and Tuntung Pandang. Stages are not in accordance with the concept of Sayyid Khitbah Sabiq is Bacarian Tatuha Kampung and Tuntung Pandang, and appropriate is the stage Bapara. In accordance with the concept stage Bapara Khitbah Sayyid Sabiq because the essence of the thing is to know the condition and status of women desired men, well with intermediaries and direct others to ask themselves. Stages Bacarian Tatuha Kampung and Tuntung Pandang incompatible with the concept of Khitbah Sayyid Sabiq, because there is no essence of ease in these stages, while the concept of Khitbah Sayyid Sabiq facilitate ease in implementation Khitbah.

Pembahasan dalam tulisan ini berkonsentrasi pada Tradisi Basasuluh yang terdapat di Suku Banjar. Dalam tradisi tersebut terdapat beberapa tahapan yang dilakukan oleh laki-laki yang jika ditinjau dari konsep Khitbah Sayyid Sabiq memiliki kesesuaian dan ketidaksesuaian, sehingga perlu pengkajian dan pendeskripsian pelaksanaan Tradisi Basasuluh Suku Banjar ditinjau dari konsep Khitbah Sayyid Sabiq. Jenis penelitian ini adalah empiris dengan pendekatan deskriptif kualitatif, dan dianalisis menggunakan konsep Khitbah Sayyid Sabiq. Hasil analisis menyimpulkan bahwa pihak laki-laki harus melakukan Bacarian Tatuha Kampung, Bapara dan Tuntung Pandang. Tahapan yang tidak sesuai dengan konsep Khitbah Sayyid Sabiq adalah Bacarian Tatuha Kampung dan Tuntung Pandang, dan yang sesuai adalah tahapan Bapara. Pada tahapan Bapara sesuai dengan konsep Khitbah Sayyid Sabiq, sebab esensi hal tersebut adalah ingin mengetahui kondisi dan status dari perempuan yang diinginkan laki-laki, baik dengan perantara orang lain maupun langsung menanyakan sendiri. Tahapan Bacarian Tatuha Kampung dan Tuntung Pandang tidak sesuai dengan konsep Khitbah Sayyid Sabiq, sebab tidak ada esensi kemudahan dalam kedua tahapan tersebut, sedangkan konsep Khitbah Sayyid Sabiq mengutamakan kemudahan dalam pelaksanaan Khitbah.

Abolition of speak Indonesian ability for foreign workers (TKA) it certainly will make Indonesia as a target for foreign workers. Tht is why the use of foreign workers eligible to be reviewed in the survey maslahah mursalah. Ths study include into the research that examines the normative principles of law. The results of this study indicate that the regulation changes of foreign workers usage in the Minister of Labor Regulation Number 16 in 2015 about Procedures of Foreign Workers usage reviewed based on the principle of employment is inappropriate with the principles of employment, such as the principle of non-discrimination that is about Indonesian repeal mandatory requirement for foreign workers. While in maslahah mursalah theory, requirements to upload licensing documents through the online system, and the abolition of Indonesian requirements for foreign workers is also not appropriate because of the changes in these terms, makes it easier for foreign workers to work in the territory of Indonesia.

Penghapusan kemampuan berbahasa Indonesia bagi Tenaga Kerja Asing (TKA) bisa dipastikan akan menjadikan Indonesia sebagai sasaran bagi TKA. Sebab itulah penggunaan TKA layak untuk dikaji dalam tinjauan maslahah mursalah.Penelitian ini termasuk ke dalam penelitian normatif yang meneliti tentang asas-asas hukum. Hasil penelitian ini menunjukkan bahwa perubahan ketentuan penggunaan TKA dalam Peraturan Menteri Ketenagakerjaan No. 16 Tahun 2015 tentang Tata Cara Penggunaan TKA ditinjau berdasarkan prinsip ketenagakerjaan belum sesuai dengan prinsip-prinsip ketenagakerjaan, seperti prinsip non diskriminasi yaitu tentang pencabutan syarat wajib Bahasa Indonesia bagi TKA. Sedangkan dalam teori maslahah mursalah, persyaratan untuk mengunggah (upload) dokumen perizinan melalui sistem online dan dihapusnya syarat bahasa Indonesia bagi TKA juga belum sesuai karena dengan perubahan ketentuan tersebut, memudahkan bagi TKA untuk bekerja di dalam wilayah Indonesia.

Looking at the phenomenon purchase transactions are growing today, a lot going on sale and purchase of Clash of Clans Account (COC) through online, as happened in the Facebook group “Sell Buy Clash Of Clans Indonesia”. In the case of sale and purchase of Clash of Clans Account (COC) of the goods bought and sold does not belong to gamers, but belongs to the game master. As in the object of sale and purchase of goods bought and sold the goods can be used, the goods are in the hands diakadkan and reserved people who do contract. But the issue this time the goods are bought and sold is not privately owned but belongs to the game master. But in reality rife Clash of Clans Account bought and sold, where buying and selling did not meet the elements that exist in buying and selling, but selling is still rife among gamers.

Melihat fenomena transaksi jual beli yang berkembang saat ini, banyak terjadi jual beli Account Clash of Clans (COC) melalui online, seperti yang terjadi di grup Facebook “Jual Beli Clash Of Clans Indonesia”. Pada kasus jual beli Account Clash of Clans (COC) tersebut barang yang diperjualbelikan bukan milik pemain game, melainkan milik game master. Sebagaimana dalam objek jual beli barang yang diperjualbelikan yakni barang dapat dimanfaatkan, barang yang diakadkan ada ditangan dan milik orang yang melakukan akad. Namun dalam permasalahan kali ini barang yang diperjualbelikan bukan milik pribadi melainkan milik game master. Akan tetapi dalam kenyataannya Account Clash of Clans marak diperjualbelikan, yang mana jual beli ini tidak memenuhi unsur-unsur yang ada dalam jual beli, akan tetapi jual beli tersebut masih marak di kalangan gamer.

Published: January 2017

Sistem pernapasan adalah sistem organ yang memenuhi oksigen tubuh. Merokok dapat menyebabkan perubahan struktur dan fungsi sistem pernapasan serta gangguan aliran udara. Penelitian ini bertujuan untuk menentukan karakteristik gangguan aliran udara pada sistem pernapasan perokok aktif, dengan analisis bilangan Reynolds. Pengukuran dilakukan menggunakan alat Spirometer Vernier Ordo SPR-BTA, yang dihubungkan ke komputer melalui aplikasi Logger-Pro untuk mengukur volume paru-paru dan menghitung flow rate (aliran udara) paru. Dari 56 sampel orang perokok aktif berusia 22 tahun yang memiliki Indek Massa Tubuh (IMT) 18-25 kg/m2, yang memiliki aktifitas olahraga antara 0-2 kali per minggu, dan jumlah konsumsi rokok perhari antara 3-24 batang. Data flow rate yang terekam dianalisis menggunakan program Matlab R2013a untuk mendapatkan bilangan Reynolds. Uji korelasi Pearson antara bilangan Reynolds dengan  flow rate dan jumlah konsumsi rokok untuk menunjukkan hubungannya.  Hasil perhitungan analisis bilangan Reynolds didapatkan karakteristik aliran dikatakan laminer jika nilai bilangan Reynolds 0-2300 dan didapatkan sebanyak 7 orang (13%) dari sampel, karakteristik aliran dikatakan transisi dengan nilai bilangan Reynolds antara 2300-4000 dan didapatkan sebanyak 47 orang (84%) dari sampel dan karakteristik aliran dikatakan turbulen dengan bilangan Reynods lebih dari 4000 dan didapatkan sebanyak 2 orang (3 %) dari sampel. Hasil uji statistik antara bilangan Reynolds dengan flow rate didapat p=0,001 dan  r =1,00 dan uji korelasi bilangan Reynolds dengan jumlah konsumsi rokok didapat p= 0,001 , r=0,960 menunjukkan ada hubungan signifikan, dengan koefisien korelasi yang kuat. Sehingga dapat disimpulkan bahwa perilaku merokok menyebabkan gangguan aliran udara, namun ada faktor lain yang juga mempengaruhi yaitu aktivitas, dan lama merokok.

Abstract: Total solar eclipse on March 9, 2016, could only be observed optimally in Indonesia. It’s the best condition to analyze the intensity fluctuation of corona. Intensity data retrieval can  be done under the total solar eclipse because the corona are visible at that time. The data retrieval did not use coronagraph, but DSLR camera which connected to a telescope. This became a simple acquisition system. Intensity analysis was obtained by using IRIS 5.59 software and it has  200 pixels length in the corona. Height by intensity based data between 8,895.58-15,099.72 was equivalent to 4,000 km – 40,000.46 km from the defined solar’s surface.

Development of Expressed Sequence Tag-Simple Sequence Repeat (EST-SSR) markers derived from public database is known to be more efficient, faster and low cost. The objective of this study was to generate a new set of EST-SSR markers for broccoli and its related species and their usefulness for assessing their genetic diversity. A total of 202 Brassica oleracea ESTs were retrieved from NCBI and then assembled into 172 unigenes by means of CAP3 program. Identification of SSRs was carried out using web-based tool, RepeatMasker software. Afterwards, EST-SSR markers were developed using Primer3 program. Among the identified SSRs, trinucleotide repeats were the most common repeat types, which accounted for about 50%. A total of eight primer pairs were successfully designed and yielded amplification products. Among them, five markers were polymorphic and displayed a total of 30 alleles with an average number of six alleles per locus. The polymorphic markers were subsequently used for analyzing genetic diversity of 36 B. oleracea cultivars including 22 broccoli, five cauliflower and nine kohlrabi cultivars based on genetic similarity matrix as implemented in NTSYS program. At similarity coefficient of 61%, a UPGMA clustering dendrogram effectively separated 36 genotypes into three main groups, where 30 out of 36 genotypes were clearly discriminated. The result obtained in the present study would help breeders in selecting parental lines for crossing. Moreover, the novel EST-SSR markers developed in the study could be a valuable tool for differentiating cultivars of broccoli and related species.

Published: January 2017

Somatic embryogenesis is a technique for regenerating embryos derived from somatic cells of various plant species. This technique along with the utilization of plant growth regulator (PGR) might benefit for mass propagation and improvement of plant species through biotechnological tools. The study aimed to determine the effect of different plant growth regu-lators, namely 6-benzyladenine (BA) and thidiazuron (TDZ) on the embryogenic callus induction as well as casein hydrolysate and malt extract on the somatic embryo development of mangosteen. The explants used were in vitro young stems of mangosteen clone Leuwiliang. This study consisted of two experiments, namely induction of embryogenic callus and formation of somatic embryo. The first experiment was arranged as factorial in a completely randomized design with BA (0 and 0.7 mg l-1) as the first factor and TDZ (0, 0.1, 0.5 and 1.0 mg l-1) as the second factor. The second experiment consisted of four treatments, i.e. casein hydrolysate and malt extract at the rate of 500 and 1,000 mg l-1. The results showed that the best medium for embryogenic callus induction was MS supplemented with 0.1 mg l-1 TDZ, which resulted semifriable calli. Casein hydrolysate and malt extract could not induce the formation of somatic embryos. After two times subcultures on the same MS medium supplemented with 0.5 mg l-1 TDZ and 0.7 mg l-1 BA, a total of 33.8 somatic embryos per explant was induced. The successful somatic embryogenesis would support mangosteen breeding and in vitro mass propagation program.
