A private information retrieval (PIR) scheme allows a user to retrieve file from database without revealing any on the being requested. As of now, PIR schemes have been proposed for several kinds storage systems, including replicated and MDS-coded systems. However, problem constructing regenerating codes has sparsely considered. code is whose codewords are distributed among nodes, enabling effi...

Background & Aims of the Study: In order to design membrane bioreactors (MBR) properly, it is essential to comprehend the behavior of microorganisms in such wastewater treatment processes. Materials & Methods: In this study, a lab-scale MBR process was operated to determine the biokinetic coefficients of the MBR system under different MLSS concentrations of 6800, 7000, 74...

Classification learning applies to a wide range of tasks, from diagnosis and troubleshooting to pattern recognition and keyword assignment. Many methods have been used to build classification systems, including artificial neural networks, rule-based expert systems (both hand-built and inductively learned), fuzzy rule systems, memorybased and case-based systems and nearest neighbor systems, gene...

Oily wastewater is generated from various sources within the petrochemical industry, including extraction, refining and processing, storage, transportation. Over years, large volumes of oily this industry have made their way into environment, negatively affecting human health, economy. The raw waters can differ significantly complex features, making them difficult to treat. Membrane bioreactors...

Membrane bioreactor-reverse osmosis process (MBR-RO) is widely applied in wastewater treatment, especially when high-quality treated water needed. Although MBR shows better performances the removal of pathogens than conventional activated sludge process, stable operation RO latter step MBR-RO depends on residual bacteria filtrate microfiltration membranes. Species and sizes found with 0.2 μm po...

Two different membrane treatment scenarios have been applied for of the high strength dark color alkaloid industry wastewater. A bioreactor (MBR) system having separately UF and MF membranes was operated with raw wastewater (scenario-A) anaerobically pre-treated (scenario-B). NF 270, 90 RO (XLE) were used as a polish-ing step at two recovery ratios 50% 75% both scenarios. In scenario-A, COD re-...

During China’s rapid economic development and urbanization, numerous cases of urban malodorous black river (MBR) have occurred. MBR refers to a polluted that smells bad, is almost in color, has no aquatic plants or animals, consequently causes many social environmental problems. The Chinese government sought public participation during the whole process treatment as part comprehensive action pl...

a membrane bioreactor (mbr) system based on a dead-end immersed hollow fiber membrane and filamentous fungus aspergillus oryzae were used for treatment of baker’s yeast wastewater. the fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. average organic loading rate of 4.2 kg cod/m3.d was entered the bioreactor. mbr system was able to redu...

Masyarakat Berpenghasilan Rendah (MBR) adalah masyarakat yang mempunyai keterbatasan daya beli sehingga perlu mendapat dukungan pemerintah untuk memperoleh fasilitas sosial ekonomi melalui program MBR. Meningkatnya penduduk miskin Kota Surabaya diikuti dengan meningkatnya jumlah MBR banyaknya ingin mendapatkan bantuan meningkat. Program akan dikelompokkan berdasarkan 40% berstatus terendah dika...

Mountains provide as much as 90-100% of the freshwater to surrounding basins in arid and semiarid regions because of their distinctive and complex topography, and the consequent effects on precipitation (P) and evapotranspiration (ET). One of the primary objectives of this dissertation is to estimate mountain-block recharge (MBR), an important component of the mountain contribution to groundwat...
