High Amylase Production by a Novel Strain of Bacillus amyloliquefaciens M37 Isolated from Can Gio Mangrove Forest, Vietnam

Amylases are one of the most important industrial enzymes and find applications in many areas such as textiles, chemicals, food, and pharmaceuticals. Most of the amylases are derived from microbes. The objective of the present study was to evaluate amylase production by a bacterium isolated from the Can Gio mangrove forest. The bacterium was identified as a species of genus Bacillus based on morphological and biochemical characteristics. The analysis of 16S rRNA sequences was then confirmed that this strain belonged to Bacillus amyloliquefaciens species (100% similarity). The effect of culture conditions such as temperature, pH, and carbon sources on amylase production through shake-flask culture was investigated. Maximum amylase activity of 904 IU/mL was obtained after 24 h of cultivation in LB medium containing 1% soluble starch at 35oC and pH 7.0. The highest enzyme activity of 1279 IU/mL was achieved in the bioreactor after 30 h of cultivation at optimum conditions. In addition, B. amyloliquefaciens M37 can grow on soybean meal medium. The high bacterial cell number of 456 × 109 CFU/g and amylase activity of 1039 IU/g were obtained after 36 h of cultivation. This newly isolated B. amyloliquefaciens M37 could be a potential producer for industrial amylase production and probiotics with commercial implications.
Zakat Sebagai Pengurang Penghasilan Kena Pajak

Zakat memiliki peranan penting bagi kepedulian sosial seorang Muslim dimana dalam sebagian hartanya ada yang merupakan hak orang lain yang wajib dikeluarkannya yang sesuai dengan ketentuan Undang-undang No. 38 Tahun 1999. Zakat merupakan ibadah yang bukan hanya berdimensi vertikal antara seorang Muslim dengan Allah Swt, namun zakat juga merupakan bentuk kepedulian sosial seorang Muslim. Pelaksanaan zakat sebagai pengurang penghasilan kena pajak yang dilaksanakan di Kota Pekanbaru sudah terlaksana akan tetapi pengurangan pajak bagi pembayar zakat masih minim dilakukan oleh wajib pajak orang pribadi, salah satu penyebabnya yaitu bagi wajib pajak yang tahu akan aturan tentang perlakuan zakat atas penghasilan dalam perhitungan penghasilan kena pajak tetapi mereka cenderung belum bisa melaksanakannya karena hal tersebut dianggap merepotkan. Sementara bagi wajib pajak yang belum tahu karena belum adanya sosialisasi secara umum akan adanya pengurangan pajak bagi pembayar zakat yang dibentuk dan disahkan oleh pemerintah. Disarankan bagi pemerintah untuk gencar melakukan sosialisasi mengenai penerapan zakat sebagai pengurang penghasil kena pajak.
A Systematic Review of Methods for Business Knowledge Extraction from Existing Software Systems

Software maintenance and evolutions often result in large cost overruns and delayed delivery of required changes or improvements. As numerous studies have shown, adopting software to meet ever-changing business needs constitutes a major part of the software maintenance cost. The demand to facilitate software maintenance has led to the emergence of dierent methods for automated knowledge extraction from source code and other artefacts of existing software systems. This paper presents a systematic literature review of peer-reviewed conference and journal articles on this topic. The review has been undertaken to summarise the state-of-the-art in the research field, identify any gaps and explore possible directions for the further research. In this review, 7 digital libraries were searched and 24 papers dealing with the topic were identified and classified according to the four dimensions: extracted business knowledge kind, extraction techniques, kinds of software artefacts used as input sources, and extracted knowledge representation forms. The results of this study indicate that the research field is still immature and requires more comprehensive research. The results also show that there is a minority of methods that rely on widely adopted business knowledge classification schemes and only very few of methods employ standards for knowledge representation. It is believed that this review and classification scheme proposed in the paper would serve as a guide for both researches and practitioners in the further studies.
Node Reliability in WDM Optical Network

The Wavelength Division Multiplexing (WDM) technology has significantly enhanced the performance and reliability of optical components. Still failures occur. Due to the massive increase of bandwidth supported by fiber networks it becomes extremely important to identify the impact of individual failures may have on the network performance. Node failures in a WDM optical network result in a very high value of Call Drop Probability (CDP). In a backbone network, a node usually carries a huge amount of data and a low CDP is desirable. This paper focuses on understanding the different parameters that affect the reliability of optical networks with emphasis on failures caused due to the optical components comprising the network infrastructure. One algorithm has been developed for calculation of node reliability in WDM optical network. The algorithm is implemented in NSFNET (National Science Foundation Network), Ring and Mesh topology. The parameters affecting the Node Reliability of the optical network are presented, discussed and compared. The different scenarios under study are based on a national USA network topology i.e. NSFNET.
Design of 3-Dimension Remote Controller Applying the EMD Algorithm which Attenuates the Effect of Noise

In this study, a remote controller was designed using localization technique. The designed remote controller system consists of infrared transmit/receive module for time synchronization, ultrasonic transmit/receive module for measuring the TOA value, and micro-controller for processing the measured data value. For the position estimation method of remote controller, the Savarese method was used which does not have a problem of diverging solution depending on initial value. The noise included in the measured value was removed by separating the signal and noise with the use of EMD method which is the non-stationary signal analysis technique. The designed system was tested by constructing a simulation environment, and the improvement of accuracy and precision for the application of EMD method was examined.
Adding active clamping and soft switching to boost-flyback single-stage isolated power-factor-corrected power supplies

Single-stage isolated power-factor-corrected power supplies (SSIPP) have the attractive features of fast regulation and a single control loop. However, SSIPP circuits also have higher voltage stress and heavier loss (when compared with a normal DC-DC power converter), which severely limit their practical applications. In this paper, the authors propose to add active clamping to SSIPP to recycle the energy trapped in the leakage inductance of their transformer (to keep the switch voltage stress low) and to achieve soft switching of their electronic devices (to further reduce the loss). This arrangement significantly improves the viability of SSIPP for practical applications. The auxiliary active-clamping transistor in the proposed circuit uses the same control/driver circuit as the main switching transistor. Simulations and experimental works verifying the operation of the converter are reported.
Quantification of Optimal Target Reliability for Seismic Design: Methodology and Application to Midrise Steel Buildings

Quantification of the optimal target reliability based on the minimum lifecycle cost is the goal standard for calibration of seismic design provisions, which is yet to be fully-materialized even in the leading codes. Deviation from the optimally-calibrated design standards is significantly more pronounced in countries whose regulations are adopted from the few leading codes with no recalibration. A major challenge in the quantification of optimal target reliability for such countries is the lack of risk models that are suited for the local construction industry and design practices. This paper addresses this challenge by presenting an optimal target reliability quantification framework that tailors the available risk models for the countries from which the codes are adopted to the local conditions of the countries adopting the codes. The proposed framework is showcased through the national building code of Iran, which is adopted from the codes of the United States, using a case study of three midrise residential steel building archetypes. The archetypes have various structural systems including intermediate moment-resisting frame (IMF) and special concentrically braced frame (SCBF). Each of these archetypes are designed to different levels of the base shear coefficient, each of which corresponds to a level of reliability. To compute the lifecycle cost, the initial construction cost of buildings is estimated. Next, robust nonlinear models of these structures are generated, using which the probability distribution of structural responses and the collapse fragility are assessed through incremental dynamic analyses. Thereafter, the buildings are subjected to a detailed seismic risk analysis. Subsequently, the lifecycle cost of the buildings is computed as the sum of the initial construction cost and the seismic losses. Finally, the optimal strength and the corresponding target reliability to be prescribed are quantified based on the notion of minimum lifecycle cost. The results reveal a 50-year optimal reliability index of 2.0 and 2.1 for IMF and SCBF buildings, respectively and an optimal collapse probability given the maximum considered earthquake of 16% for both systems. In the context on the case study of the national building code of Iran, the optimal design base shear for IMF buildings is 40% higher than the current prescribed value by the code, whereas that of SCBF buildings is currently at the optimal level.
Evidence of gender equity in pupils’ achievement in phonics, when exposed to adult and children-generated illustrations

The study examined evidence of gender equity in pupils achievement in phonics, when exposed to adult and children-generated illustrations in Njikoka Local Government Area of Nigeria. The study employed a non-equivalent quasi‐experimental 2 x 2 factorial research design. Some 158 primary two pupils from 4 schools were used for the study. The English Achievement Test (EAT) was used to collect data. Three hypotheses were tested. The data were analysed using descriptive statistics and Analysis of Covariance (ANCOVA). The results showed that there was a significant main effect for the mode of illustration on pupils’ achievement in phonics F(1,153) = 21.315, p=. 000; there was no significant main effect of gender F(1,153) = 1.082, p =. 300, and there was no significant interaction effect of mode of illustration and gender F(1,153) = . 701, p =. 404. The study recommended that since the children-generated illustrations were more effective in teaching phonics and enhancing pupils achievement in phonics, the Ministries of Education should ensure that textbook authors incorporate children-generated illustrations in the instructional materials for pupils in primary schools. Mode of illustration had no differential effects on male and female pupils achievement in phonics. As such the present system of teaching both males and females in the same class should be encouraged. Authors and publishers of children’s books should engage pupils’ in illustrating their books.
A Statistical Methodology for the Analysis of the Life-Cycle of Reusable Containers

Abstract The effectiveness of recycling reusable containers as a means of spreading container costs depends on a knowledge of container life-cycle characteristics expressed through parameters such as trip-page, trip duration, loss rate, and expected useful life. Most existing estimation methods in industry are based on static ratios of inventory records. This paper describes, with numerical examples, a rigorous approach for data analysis and modeling which yields the needed parameters through a systematic examination of inherent statistical properties in routinely available data on container issues and returns. The results are important to functions such as pricing, marketing, accounting, and inventory and financial control in a container filling plant.
Faunistic Contributions, and Ecological and Zoogeographical Evaluations on Staphylininae (Coleoptera: Staphylinidae) Fauna of Eastern Black Sea Region of Turkey

ABSTRACT The focus of this study is to make contributions to Staphylininae (Coleoptera: Staphylinidae) fauna of Turkey with additional material which was composed of specimens collected from Eastern Black Sea Region between 2013 to 2015. Totally, 71 taxa of 19 genera belonging to 3 tribes of Staphylininae were recorded. Among them, Ocypus almensis Coiffait, 1967 and Quedius edmundi Coiffait, 1969 are collected from Turkey for the first time. Moreover, first detailed localities for Philonthus picimanus (Ménétriés, 1832), Philonthus splendens sideropterus Kolenati, 1846 and Tasgius globulifer (Geoffroy, 1785) are given with this study. General distribution pattern of the species depending on collecting months, altitudes and habitats, and species diversity of the region are presented and compared. Distribution of species in other regions of Turkey and zoogeographical regions are included, and the zoogeographical statuses of species are discussed. European and Middle Eastern species compose the most of the collected species. Since the region is transition between Caucasia and Europe through the Anatolian peninsula, species composition reflects the regional characters, and consequently, represents this pathway.
Advanced characterisation of multi-recycled warm asphalt pavement (MRWAP) with high content of recycled asphalt pavement

The main results of the French collaborative project Improvmure, funded by the National Research Agency are presented. A very wide study was performed on bituminous mixtures produced on experimental sites or in laboratory at different scales (semi-industrial process or lab process). Objectives were to evaluate the influence of the recycling rate (0%, 40% and 70%), the number of successive recycling cycles (from 1 to 3 cycles), and the manufacturing process (hot mix or warm mix using additives or foamed bitumen). The impact was studied in laboratory on the emitted fumes during the production process, on the properties used for mix design (compactability, water sensitivity, complex modulus at 15°C/10 Hz, fatigue), on advanced thermomechanical behaviour (linear viscoelasticity, crack behaviour at low temperature, crack propagation) and on surface properties (skid resistance). The paper gathers many valuable results, showing the possibility to recycle bituminous mixtures multiple times, at high rates and with warm manufacturing process.
Investigation of population structure and molecular genetic diversity under coastal agro-ecosystem in rice (Oryza sativa L.)

Molecular markers are useful tools for evaluating genetic diversity and determining cultivar identity. Thirty nine simple sequence repeat (SSR) markers were selected in order to evaluate the genetic diversity in 88 genotypes. A total of 115 alleles were detected in 39 SSR polymorphic markers. The number of alleles per marker ranged from 1 to 5, with an average of 3 alleles per locus. An average polymorphism information content value of 0.5615 was recorded. It ranged from zero (RM431, RM379 and RM262) to 0.6476 (RM324), indicating significant genetic diversity among and within the rice accessions of the present study. The average observed heterozygosity was 0.1136, while the average expected genetic diversity was 0.6105. A dendrogram constructed using the Unweighted Pair Group Method with Arithmetic means (UPGMA), grouped the 88 rice genotypes into three well differentiated major clusters. The structured program without prior information provided support for the existence of three genetically distinct clusters (K=3).
Improved coupling for aperture coupled microstrip antennas

An aperture shape that gives significantly improved coupling for an aperture coupled microstrip antenna is described. This ‘dogbone’ aperture consists of the usual rectangular slot, augmented with loading slots at each end. Measured data show an increase of more than three for the resonant input impedance of an antenna using the dogbone-shaped aperture, as compared with the input impedance of the same antenna with a rectangular slot of the same overall length. The field distributions of both slots are also measured, and compared.
New design for low-loss star couplers and arrayed waveguide grating devices

We propose a new loss reduction method in star couplers employing UV-written tapers that replace the free propagation region in the conventional star couplers and apply them to an arrayed waveguide grating (AWG) device. The insertion loss of the new AWG device can be reduced to 0.31 dB, which is about 0.7 dB lower than that of the AWG without UV-written tapered waveguides.
Evaluation of Machine Learning Methods for Monitoring the Health of Guyed Towers

This paper presents the development of a methodology to detect and evaluate faults in cable-stayed towers, which are part of the infrastructure of Brazil’s interconnected electrical system. The proposed method increases system reliability and minimizes the risk of service failure and tower collapse through the introduction of predictive maintenance methods based on artificial intelligence, which will ultimately benefit the end consumer. The proposed signal processing and interpretation methods are based on a machine learning approach, where the tower vibration is acquired from accelerometers that measure the dynamic response caused by the effects of the environment on the towers through wind and weather conditions. Data-based models were developed to obtain a representation of health degradation, which is primarily based on the finite element model of the tower, subjected to wind excitation. This representation is also based on measurements using a mockup tower with different types of provoked degradation that was subjected to ambient changes in the laboratory. The sensor signals are preprocessed and submitted to an autoencoder neural network to minimize the dimensionality of the resources involved, being analyzed by a classifier, based on a Softmax configuration. The results of the proposed configuration indicate the possibility of early failure detection and evolution evaluation, providing an effective failure detection and monitoring system.
A New Version of Prototype for Mechanical Distribution of Natural Enemies

The aim of this research is to assess the performances of a new version of the device patented by University of Catania and already used in natural enemy distribution trials on greenhouse vegetable crops. The prototype has been designed and constructed by Mechanics Section of DIA in order both to increase the work capacity and to promote a low impact pest control, which respects the environment and consumers' and farmers' health. This version has the same working principle of the former prototype, but materials and dimension of the hopper, the distributor and the rotating disc have been changed. Moreover it has a handle directly carried by the worker. From the laboratory trials, the dosage and distribution mechanism of the prototype seem well suited to biological pest control strategies. Negligible or absent impact on natural enemies proves prototype efficacy and enables its usage both with technical and economic advantages on manual distribution. With this model the device performance is improved in manoeuvrability. Consequently, greater work capacity and higher work quality will be achieved in greenhouses and in field.
Science and Technology Parks and University Collaborations

Science and technology parks (STP) are seen as a catalyzer for the economic and industrial development for developing countries. For future STPs , it’s needed to determine from beginning to last version of them, their properties, similar and different structures, regional priorities, expectations and etc. This study will demonstrate to create a new science and technology parks, what the potential advantages and disadvantages are and what the factors should be taken account, etc. as a compiling review. The success of the STPs close related to University collaborations. Universities are supporting the STP firms as researchers and laboratories. University based STPs have much more benefits for researches and innovations, incubation activities, start-up/spin off firms and entrepreneurship opportunities.
The Effect of Incorporating an Exergame Application in a Multidisciplinary Weight Management Program on Physical Activity and Fitness Indices in Children with Overweight and Obesity

Children with overweight/obese (OW/OB) have low physical activity (PA) levels and excessive daily screen times. Although access to personal smartphones may complicate restricting sedentary screen time, these devices may be used to promote PA and improve fitness. Therefore, we aim to examine the impact of incorporating an exergame application (APP) into an existing weight management program on BMI, physical activity, fitness levels, and attitude toward PA among OW/OB children. Seventy-nine children (51% girls), median age 10 years, completed an established 5-month weight management program. The intervention included structured PA sessions (2/week), nutritional, and behavioral counseling. An exergame app was installed on the smartphones of the intervention group (APP, n = 32). BMI, physical fitness, PA level, and attitudes toward PA were assessed before and after the intervention. BMI decreased (p < 0.0001) in both groups by 0.67 kg/m2 (Q1, Q3: −1.36–0.12). There were improvements in more fitness components in the APP group than controls, with significantly greater improvements in aerobic fitness (p = 0.038), speed and agility (p = 0.01), and leg strength endurance (p = 0.05) compared to controls. PA levels increased similarly in both groups during the intervention period. The incorporation of an exergame application leads to more significant improvements in fitness components. These findings support the use of exergame apps to improve fitness in OW/OB children.
A NOVEL CENTRALISED WIND FARM CONTROLLER UTILISING VOLTAGE CONTROL CAPABILITY OF WIND TURBINES

As many other European countries, Ger- many is now going to install large wind farms off shore. The turbines used in such farms are variable speed wind turbines, either doubly-fed induction generators or syn- chronous generators with full size converter. These tur- bines offer the capability of decoupled active and reactive power control. Modern onshore and offshore wind farms must provide reactive power or voltage control at the point of common coupling (PCC) on demand of the system op- erators. But fast changes in active power as a result of changing wind speeds can lead to fast changes in the volt- age at the PCC. In this paper, a new wind farm control system will be presented which makes use of local voltage controller at each turbine using voltage reference settings from the wind farm controller. The controller is charac- terized by a hierarchical system structure with a high degree of autonomous local control capability. The pro- posed approach is demonstrated by simulation results conducted for a wind farm, currently under planning in Germany.
