Gender differences in a Drosophila transcriptomic model of chronic pentylenetetrazole induced behavioral deficit

A male Drosophila model of locomotor deficit induced by chronic pentylenetetrazole (PTZ), a proconvulsant used to model epileptogenesis in rodents, has recently been described. Antiepileptic drugs (AEDs) ameliorate development of this behavioral abnormality. Time-series of microarray profiling of heads of male flies treated with PTZ has shown epileptogenesis-like transcriptomic perturbation in the fly model. Gender differences are known to exist in neurological and psychiatric conditions including epileptogenesis. We describe here the effects of chronic PTZ in Drosophila females, and compare the results with the male model. As in males, chronic PTZ was found found to cause a decreased climbing speed in females. In males, overrepresentation of Wnt, MAPK, TGF-beta, JAK-STAT, Cell communication, and Dorso-Ventral axis formation pathways in downregulated genes was previously described. Of these, female genes showed enrichment only for Dorso-Ventral axis formation. Most significant, ribosomal pathway was uniquely overrepresented in genes downregulated in females. Gender differences thus exist in the Drosophila model. Gender neutral, Dorso-Ventral axis formation may be considered as the candidate causal pathway in chronic pentylenetetrazole induced behavioral deficit. Prior evidence of developmental mechanisms in epileptogenesis underscores the usefulness of fly model. Gender specific pathways may provide a lead for understanding brain dimorphism in neuropsychiatric disorders

Direct solution of higher order ordinary differential equations using one-step hybrid block methods with generalised off-step points In the presence of higher derivative

A great number of physical phenomena can be expressed as initial or boundary value problems of higher order ordinary differential equations (ODEs) which may not have analytical solutions. Thus, there is a need to develop numerical methods for approximating the solution of higher order ODEs. One of the well-known direct methods which frequently employed is block method. Even though this method is capable of finding the approximate solutions at several points simultaneously, it fails to overcome the zero-stability barrier. Thus, a hybrid block method was introduced to tackle this drawback. The main benefit of this method is its ability of using data at off-step points which contribute to better accuracy. Most of the existing hybrid block methods, however, only focus on specific off-step point(s) in deriving the methods with the exception of the method proposed by Abdelrahim in 2016. Although he has successfully developed one-step hybrid block methods with generalised off-step point(s) for solving high order ODEs directly, nevertheless, the methods are only confined to initial value problems. Moreover, he did not consider higher derivative in developing those methods. Thus, this study introduced new one-step hybrid block methods with generalised off-step point(s) in the presence of higher derivative for directly solving higher order ODEs. In developing these methods, a power series was used as an approximate solution to the problems of ODEs of order m. The power series was interpolated at m points, while its mth and (m+1)th derivatives were collocated at all points in the given interval. Investigations on the properties of the new methods such as order, error constant, zero-stability, consistency, convergence and region of absolute stability were also carried out. Several initial and boundary value problems of higher order ODEs considered in literature were then solved by using the newly developed methods in order to investigate the accuracy of the solution in terms of error. The numerical results revealed that, in general, the new methods were able to produce smaller errors compared to the existing methods in solving the same problems. In conclusion, this study has successfully developed viable methods for directly solving both initial and boundary value problems of higher order ODEs

Measuring Islamic Stock Performance in Indonesia with A Modified Sharpe Ratio

Since the late 1960s, one of the stock performance analysis tools commonly used is Sharpe Ratio. The Sharpe Ratio consists of three components, namely stock return, risk-free returns, and stock risk. Many studies approach risk-free returns with interest rates, including when measuring the performance of Islamic stocks, while interest rates are prohibited in the concept of Islamic finance. Moreover, the stock risk is measured by a standard deviation which assumes returns are normally distributed, while many stock returns are non-normally distributed. This paper intends to measure the performance of Islamic stocks listed on the Indonesian Stock Exchange (IDX) for the period of January 2011 to July 2018 using a modified Sharpe Ratio. The ratio is modified by replacing the interest rate with four approaches: eliminating the interest rate, changing with zakah rates, changing with inflation, changing with the nominal gross domestic product, and replacing the risk measurement from Standard Deviation to Value at Risk (VaR). The findings provide almost the same results as the original measurement and thus, show very high suitability for using these models in other circumstances. Therefore, on the concept of Islamic finance, risk-free returns can be measured using these four approaches, especially inflation and GDP. This study also recommends inflation and GDP to measure risk-free returns in the Sharia's Compliant Asset Pricing Model (SCAPM) or Islamic Capital Asset Pricing Model (ICAPM).====================================================================================================ABSTRAK – Pengukuran Kinerja Saham Syariah di Indonesia menggunakan Sharpe Ratio Modifikasi. Sejak akhir 1960-an, salah satu alat mengukur kinerja saham yang biasa digunakan adalah Sharpe Ratio. Model Sharpe Ratio terdiri atas tiga komponen, yaitu return saham, return bebas risiko, dan risiko saham. Return bebas risiko diukur mengunakan variabel suku bunga yang digolongkan riba dan dilarang dalam konsep keuangan islam. Sedangkan risiko saham diukur dengan standar deviasi yang mengasumsikan data berdistribusi normal. Paper ini bertujuan untuk mengukur kinerja saham syariah yang terdaftar pada Bursa Efek Indonesia (BEI) untuk periode Januari 2011 sampai Juli 2018 dengan menggunakan Sharpe Ratio modifikasi. Kajian akan memodifikasi model Sharpe Ratio dengan mencari variabel alternatif penganti suku bunga dengan empat pendekatan, yaitu: menghilangkan variabel suku bunga tersebut, mengganti dengan zakat rate, mengganti dengan inflasi, dan mengganti dengan produk domestik bruto, serta mengganti standar deviasi dengan Value at Risk (VaR) sebagai pengukur risiko saham yang selanjutnya diimplementasikan pada pasar modal syariah di Indonesia periode Januari 2011 - Juli 2018. Hasil kajian menunjukkan kesesuaian yang sangat tinggi untuk hasil pengukuran kelima model tersebut. Dilihat dari kedekatan hasil pengukuran kinerja, kelima model tersebut dapat dikelompokkan menjadi dua, yaitu model dengan tingkat suku bunga, inflasi, dan PDB sebagai kelompok pertama, sedangkan model tanpa suku bunga dan tingkat zakat sebagai kelompok kedua

Penyisihan Konsentrasi Logam Zn Menggunakan Mangrove Avicennia marina

Hutan mangrove di Indonesia terutama Pulau Jawa terus mengalami degradasi akibat konversi peruntukan yaitu tambak, penebangan kayu mangrove untuk berbagai keperluan,disamping rendahnya kesadaran masyarakat tentang fungsi ekologis hutan mangrove dan ketidakpastian status kawasan. Keseimbangan ekologi lingkungan perairan pantai akan tetap terjaga apabila keberadaan mangrove dipertahankan karena mangrove dapat berfungsi sebagai biofilter, agen pengikat dan perangkap polusi, penangkap sumber pencemar yang sangat banyak dan memiliki toleransi yang tinggi terhadap logam berat. Tujuan dari penelitian ini adalah untuk menghitung seberapa besar efisiensi mangrove Avicennia  marina dalam meremoval larutan artifisial logam ZnSO4. Pada penelitian ini digunakan variabel konsentrasi polutan larutan artifisial ZnSO4 setelah dilakukan uji pendahuluan Range Finding Test. Variabel konsentrasi setelah uji Range Finding Test yaitu 100 mg/L,200 mg/L dan 300 mg/L dengan pengulangan tiga kali/triplo. Pada penelitian ini digunakan reaktor skala laboratorium dengan sistem batch. Berdasarkan hasil penelitian, efisiensi removal  mangrove Avicennia marina pada konsentrasi 100 mg/L yaitu 79,83%, pada konsentrasi 200 mg/L yaitu 70,75% dan konsentrasi 300 mg/L yaitu 67,17%

Design and Analysis of a Hyperbaric Chamber

Hyperbaric is defined as an act of operating at pressure higher than atmospheric pressure. The hyperbaric chamber is an improvised version of pressure vessel where a pressure vessel is designed in a way that the vessel can be excess via door, in order for a components to be inserted and tested at high pressure. The high pressure acted in the vessel can be maneuvered or controlled by a fluid that is pumped to the vessel. The main purpose of designing this hyperbaric chamber is to support the UTP Deep-water Research for testing a deep-water Oil and Gas instrument at high pressure. Hence, the aim of this project is to design and analyze the Hyperbaric Chamber according to the pressure vessel design guideline drawn by ASME VIII standards with the defined parameter taken by previous researcher in deep-water oil and gas field. There are four major parts designed in this hyperbaric chamber which are the vessel main body, vessel heads, nozzle instrumentation attached to the vessel and the vessel supports. The designed simulation is carried out by two mechanical engineering software which is CATIA V5R and ANSYS 14. CATIA V5R is used to drawn the virtual designed of hyperbaric chamber and then it is transferred to ANSYS for further analysis. Based on ANSYS simulation results, there are 7 critical stress points defined in the designed hyperbaric chamber. Compared with the theoretical stress calculated to the results analyzed by ANSYS, proved that the stress acted in the hyperbaric chamber wall does not failed due to over pressure at operating condition. Hence, the design is acceptable as per required design specification
