The Effect of Adsorbent Type and Ratio on Removal of Methylene Blue and Its Isotherm Adsorption (Lia Cundari) THE EFFECT OF ADSORBENT TYPE AND RATIO ON REMOVAL OF METHYLENE BLUE AND ITS ISOTHERM ADSORPTION

THE EFFECT OF ADSORBENT TYPE AND RATIO ON REMOVAL AND ISOTHERM ADSORPTION OF METHYLENE BLUE. Methylene Blue (MB) is one of the dye that are widely used in the textile industry. The wastewater from textile industry that contain MB can reduce the oxygen level in water bodies. This study aims to determine the efficiency of the adsorbent in MB removal and to analyze the isotherm adsorption. The variations conducted in this research was the type of adsorbent and its ratio. The activated carbon that used as adsorbent was fresh betel nut (Cyrtostachys lakka) activated carbon (A), regenerated betel nut activated carbon (B), and coconut shell activated carbon (Cocos nucifera) (C). The type of adsorbent was AB, AC, and BC with ratio of 1:1, 1:2, 1:3, 2:1, and 3:1. The MB concentration was analyzed by using UV-Vis spectrophotometer. Isotherm adsorption was calculated based on Freundlich and Langmuir. The best results showed that the combination of fresh and regenerated betel nuts (AB) with ratio of 3:1 can remove 97.77% of MB. The adsorption process of MB in aqueous solution followed the Langmuir model with regression over 0.99 and adsorption capacity in the range of 2.14 mg/g 3.53 mg/g.
UNBIASED SIMULATION ESTIMATORS FOR PATH INTEGRALS OF DIFFUSIONS

We develop and analyze Monte Carlo simulation estimators for path integrals of a multivariate diffusion with a general state-dependent drift and volatility. We prove that our estimators are unbiased and have finite variance by extending the regularity conditions of the parametrix method. The performance of our estimators is illustrated on numerical examples that highlight some applied problems for which our estimators apply.
Fractal Description of the Spatial and Temporal Variability of Soil Water Content Across an Agricultural Field

Abstract There is an increasing interest in quantifying the space-time variation of soil properties. This issue offers a unique set of problems that have been addressed using various methods. Here, the spatial and temporal scaling behavior of topsoil water content at the field scale was explored using the fractal approach. Results from fractal analysis were compared with those from other methods describing either spatial variability or temporal trends and stability of soil moisture. Time domain reflectometry probes were installed at the 0- to 20-cm depth in a clay loam soil under natural pasture in Ottawa, Ontario, Canada. Soil water content was measured 34 times at 164 points on a square grid with 10-m spacing. Mean soil water content and coefficients of variation showed significant negative linear relationship for both sampling dates (r2 = 0.783) and sampling points (r2 = 0.804). Both spatial and temporal data sets were characterized by a self-affine fractal Brownian motion model that requires two parameters, fractal dimension, D, and crossover length, l. For spatially sampled data sets at different times, D ranged from 2.589 to 2.910 and l ranged from 0.95 to 6.97 m. For temporal data sets measured on 10-m grid nodes, D was between 1.145 and 1.919 and l was from 0.069 to 9.40 days. Fractal analysis added information on the scale dependence of spatially and temporally sampled data sets, which is not taken into account by classical statistics. Also, interpretation of fractal parameters provided further insight when contrasted with temporal stability analysis. Fractal dimension and crossover length of temporal series showed spatial dependence, and ordinary kriging was used to map these two fractal parameters.
Implementation And Comparison Of Constructive Heuristics For The Heterogeneous Fleet Vehicle Routing Problem

: The purpose of this article is, firstly, to implement constructive heuristics for the Heterogeneous Fleet Vehicle Routing Problems and secondly, to compare the performance of these heuristics by taking into account the dimension of studied problems, geographical dispersion of served customers, their angular position in relation to the starting point and customer's demand variability. In our study the performance of a solution is calculated in relation to the cost generated by this one, the execution time is not taken into account because constructive heuristics provide generally acceptable solutions in very short time, in the order of a few seconds or even milliseconds, regardless of the problem size.
Nanostructured Polymers Obtained from Polyethylene-block-poly(ethylene oxide) Block Copolymer in Unsaturated Polyester

We report the phase behavior, the molecular assembly, and the crystallization in blends of unsaturated polyester resin (UP, thermoset polymer) and low molecular mass polyethylene-block-poly(ethylene oxide) (EEO, 1400 g mol-1). Liquid blends containing 2.5−25% of EEO block copolymer were prepared. At a macroscopic level, all the prepared blends are homogeneous at room temperature, exhibiting LCST-type behavior upon heating, with macrophase separation occurring at 75 °C in the studied range of compositions. Curing at a temperature lower than 75 °C prevents macrophase separation and allows the fixing of the structure obtained in the initial liquid state. In these conditions, EEO platelets exhibiting a high aspect ratio (6 nm thick, 500 nm to 1 μm long) constituted of a crystalline PE core, bordered by PEO domains, are observed in the cured state by TEM. For low EEO content, isolated lamellae are obtained. For higher content, aggregation of the lamellae is observed without real isotrope/nematic transformation.

Metadata for Business Intelligence A practical approach of software architecture Extended

: The evolution of the DW / BI environment through successive delivery of decision-making applications gives rise to the recurring need to understand the data, flows, and people that are accountable for them. Much of the information that is generated when creating these applications is either inaccessible or fragmented, hampering the action time of those involved, such as analysts who need to understand the data they see or the technicians who develop data integration processes. This research attempted to understand the tasks and interests of users interacting in a typical information-consuming environment that could benefit from the existence of a metadata repository. A possible approach to the implementation of a metadata architecture is demonstrated by describing a set of architectural concerns associated with the development of a tool that enables users to be more efficient in performing their tasks. The ADD method is used to design the architecture.
OVER-EXPRESSION OF ZmARG ENCODING AN ARGINASE IMPROVES GRAIN PRODUCTION IN MAIZE

Arginase, as one of the three key enzymes in nitrogen catabolism, the physiological role of Arg catabolism in cereal crops has not been fully clarified. Studies have shown that arginase-encoding genes play a key role in providing nitrogen to developing seedlings in many plant species.Yield is a primary trait in many crop breeding programs, which can be increased by modification of genes related to photosynthesis, nitrogen assimilation, carbon distribution, plant architecture, and transcriptional networks controlling plant development. In the present study, a maize arginase gene ZmARG was cloned and introduced into maize inbred lines by Agrobacterium tumefaciensmediated transformation. Putative transgenic plants were confirmed by PCR, Southern blotting RT-PCR analysis. The expression of the ZmARG gene increased arginase activity in several tissues in transgenic lines. Transgenic maize plants had significantly higher ear weight and 100-seed weight as compared with wild-type control. Our results suggested that ZmARG was a potential target gene for crop yield improvement.
ASSESSMENT OF GENETIC DIVERSITY OF SOME COWPEAS (VIGNA UNGUICULATA L.) CULTIVARS GROWN IN EGYPT BASED ON START CODON-TARGETED (SCOT) MARKERS

The different techniques of molecular markers have proved to play a considerable role in assessed the genetic diversity between and within different species. The genetic diversity among the seven cowpea cultivars was characterized using the twelve SCoT markers. The total number of amplicons was 169 with an average of 16.9. Among 169 amplicons, 121 were polymorphic with a level of polymorphism of 71.60%. All primers (12) were successful to identify each of the seven cowpea genotypes by unique positive and/or negative markers. Tiba cultivar showed the highest (15) number of unique markers. The presence of SCoT unique markers among the cowpea cultivars indicates the utility of the approach for fingerprinting purposes. Moreover, the dendrograms constructed from UPGMA divided the seven genotypes into two clusters. The first cluster comprises the cultivar Tiba, Dokki331 and Kaha-1. While the second cluster divided into two subclster the Kareemy7 (subcluster) was separated from other remaining 3 cultivars. The second subcluster contained Balady, Sudan and Kafr-ElShikh, two cultivars that clustered together (Sudany and Balady).
SPATIAL VARIATION IN THE CONTENT AND DISTRIBUTION OF IRON OXIDES IN SEDIMENTS OF THE GHARAF RIVER IN IRAQ

A study of the spatial distribution of iron oxides in the deposits of the Al-Gharaf river was conducted in some soils of Wasit and Thi Qar governorates due to the effect of six regulators of the Al-Gharaf river and its role in the quantitative and qualitative distribution, where the sampling areas were identified in front and rear each of the regulator, on the banks of the Al-Gharraf river channel, Within the area confined between the origin of the regulator and the channels which fed by the regulator. Soil samples were taken during spring season 2019, where 12 pedons distributed along the bank of the canal were digged in the middle of the variability in water levels between the highest and lowest levels of water and the depth of the digging is determined by the level of the water table. After bringing the samples, they were prepared for examination, and the necessary analyzes were performed on them. The results showed an increase in the total iron oxide values in soil of the front of the regulator compared to the soil at rear of the regulator in all locations and for both depths. The values of amorphous iron oxides were lower than that of Crystalline Free Iron Oxides in all the soils of the study. There was no clear and specific distribution of the values of amorphous iron oxides, either in the horizontal or the vertical plane, in the soils of the study. The values of crystalline iron oxides increased at both the surface and subsurface depths in soils of the front of the regulator compared to the soil of the rear of the regulator in all study locations. The vertical distribution of active iron values within the surface and sub-surface depths was the opposite of the distribution of the values of crystallized iron oxides. The values of active iron increased within the subsurface layers compared to the surface layers at all location. As the role of the regulators appears through their direct influence on the process of distributing iron oxides forms through sorting them according to their sizes, in addition to the role of the regulators in controlling the variability in water levels, which is reflected on its effect on the iron oxide content with the depth.
The thermal accommodation coefficients of gases. II. Determinations at room and at liquid-oxygen temperatures

The accommodation coefficients of helium, neon, argon, hydrogen and oxygen, on a tungsten surface, are smaller at liquid-oxygen than at room temperature. The accommodation coefficients of the inert gases varies, at both temperatures, approximately as the square root of the atomic weights. The increase in the accommodation coefficient of helium, with the hot-working of the wire observed by Roberts (1930), has not been confirmed for heating times up to 30 hr.

EVALUATION OF PROTHROMBIN GENE POLYMORPHISM FREQUENCY IN PATIENTS WITH ISCHEMIC STROKE IN IRAQI POPULATION

Stroke is one of the leading causes of death worldwide, and increasing evidence indicates that coagulation abnormalities cause stroke and the formation of a secondary ischemic stroke, either in the accompanying vessel or in the form of an embolus. Therefore, the balance between coagulation and fibrinolysis is a critical component of the ischemic stroke. The study population was included 75 ischemic stroke patients and 25 healthy subjects. The estimated incidence of ischemic stroke increased in the age group 65-74 years, with a significant difference (p<0.05) in comparison with the other groups. Results of coagulation tests indicated that no significant differences were found in the results of prothrombin time between the IS patients and control. A PCR-SSP technique was performed for detection prothrombin gene 20210 G/A (rs1799963) polymorphism, in ischemic stroke patients. The genotype distribution results of the 20210 G/A SNP of prothrombin gene were not showed significant differences (p>0.05) between controls (GG : n = 25, 100%; GA: n = 0; AA: n = 0) and ischemic stroke patients (GG : n = 66, 88%; GA: n = 8, 10.66%; AA : n = 1, 1.333%). The results of prothrombin time did not differ according to the prothrombin gene genotype and it statistically not significant (p>0.05) in ischemic stroke patients that carrier A allele or G allele than controls. Results showed that G allele of the 20210G/A and the mutant allele (A) was not statistically significantly linked with the ischemic stroke (OR = 0.251, 95% CI = 0.032-1.996, p = 0.16). However, the 20210 G/A mutant allelesare not entirely absent among Iraqi patients with ischemic stroke.

STOCK PRICE PREDICTION USING MICROBLOGGING DATA

- Stock market prediction is that the act of trying to work out the longer term value of a corporation stock held at some securities market. Successful prediction of a stock’s future price could yield a major profit. Volatile market makes prediction difficult. “Stock Price Prediction Using Microblogging data” a technique for predicting stock prices is developed using news articles and historical stock prices. The changes available prices of a corporation, the rises and falls, are correlated with the general public opinions being expressed in tweets this company. Understanding author’s opinion from a chunk of text is the objective of sentiment analysis. Positive news and tweets in social media a couple of company would definitely encourage people to speculate within the stocks of that company and as a result the stock price of that company would increase. A prediction model for locating and analyzing correlation between contents of tweets and stock prices so making predictions for future prices may be developed by using machine learning. stock market could be a subject that's highly littered with economic, social, and political factors. There are several factors e.g. external factors or internal factors which may affect and move the exchange. Stock prices rise and fall every second thanks to variations in supply and demand. Techniques using machine learning will give more accurate, precise and easy thanks to solve such issues associated with stock and market prices so use of regression method provides better prediction.
A Simheuristic Approach for Robust Scheduling of Airport Turnaround Teams

The problem of developing robust daily schedules for the teams turning around aircraft at airports has recently been approached through an efficient combination of project scheduling and vehicle routing models, and solved jointly by constraint programming and mixed integer programming solvers, organized in a matheuristic approach based on large neighborhood search. Therein, robustness is achieved through optimally allocating time windows to tasks, as well as allocating slack times to the routes to be followed by each team throughout their working shift. We enhance that approach by integrating discrete event simulation within a simheuristic scheme, whereby results from simulation provide constructive feedback to improve the overall robustness of the plan. This is achieved as a trade-off between the interests of each separate turnaround service provider and that of the airport as a whole. Numerical experiments show the applicability of the developed approach as a decision support mechanism at any airport.
Effect of bacterial isolates on organic and sustainable farming of medicinal plant: ashwagandha (Withania angustifolia)

A total of 104 isolates of rhizobacteria were obtained from rhizosphere and rhizoplane of Ashwagandha plants collected from three locations of Haryana. Of these 36 were from rhizosphere and 68 were from rhizoplane. All the isolates were screened for their growth promoting activities in terms of biomass production in sandy soil without addition of any organic or inorganic fertilizers. Inoculation with these isolates produced more plant biomass than control to a varying level. Only four isolates (HRP-7, RRP-8, and RRP-26 & YRP-11) produced plant biomass more than 10g/plant. Highest plant biomass was produced by inoculation of isolate YRP-11 (16.49 g/plant) followed by RRP-26 (15.86 g/plant). Isolate HRP-7 produced least plant biomass. Isolates selected on the basis of higher plant biomass production showed useful traits like nitrogen fixation, and production of growth promoting substances like indole acetic acid. Inoculation with selected isolates increased plant biomass more in presence of farmyard manure than without farmyard manure. Mixture of these isolates produced biomass at par with mixed biofertilizer formulation containing Azotobacter and phosphorus solubilizing bacteria.
EFFECT OF BLACK POLY ETHYLENE MULCH AND IRRIGATION DEFICIT ON ONION PRODUCTIVITY AND QUALITY AT WEST NORTH COAST IN EGYPT

Two experiments were conducted at Marsa Matrouh Experimental station, Marsa Matrouh governorate (latitude 31o 20’ N and longitude extends about 600 km from Alexandria in the east at 29o 50’ E to El-Salloum on the Libyan border in the west at 25°10' during two consecutive seasons (2018-2019 and 2019-2020). The aim of the currentstudy was to investigate the effect of different irrigation rates (T1, T2, T3, T4 and T5) according to 20, 40, 60, 80 and 100 percent of onion water requirements in addition (T0) rainfed treatment as a control. Irrigation treatments were assessed with soil mulching and non-mulching treatments. Results showed that, onion growth, yield and its characters significantly affected by soil mulching and irrigation treatments. The highest onion plant fresh weight and bulb yield were obtained from T4, T5 followed by T3, while T0 then T1 and T2 produced the lowest plant fresh weight and bulb yield. Soil mulching treatment positively affected plant growth and yield compared with bare soil especially in the second season when average seasonal precipitation was limited. Moreover, soil mulching with irrigation treatments deeplyenhanced WUE and IWUE especially in the second season where seasonal precipitation was limited. T1 with soil mulching recorded the highest values of WUE and IWUE (15.2, 26.5 kg/Fed-1/m-1) and (87.8, 124.3 kg/Fed-1/m-1) in two seasons respectively. On the other hand, T5 with bare soil recorded the lowest WUE and IWUE values of (9.8, 17.1 kg/Fed-1/m-1) and (6.3, 16.4 kg/Fed-1/m-1) in first and second season respectively. Our study recommended that, under north eastern Mediterranean coast, sufficient onion yield can be achieved with soil mulching even ifirrigation water deficit within 50 to 60 percent of onion water requirements especially throughout heavy rain seasons. Investment ratio calculations led to conclude thatit can be recommend that, under Marsa Matrouh region conditions, the necessity of using black plastic mulch combined with 40–60 percent of water requirements as a supplemental irrigation is required for onion production to save water as well as to achieve high return. Key wards: Onion, rainfed, soil mulching, irrigation water deficit, onion yield, wue and investment ratio
Ion transport in polypyrrole and a polypyrrole/polyanion composite

The ionic conductivities of polypyrrole/poly(styrenesulfonate) (PPY/PSS) and polypyrrole perchlorate (PPY/ClO 4 - ) films on electrodes have been measured in 0.2 M NaClO 4 (aq) as a function of oxidation level by impedance spectroscopy. As the oxidation level is increased, the ionic conductivity of PPY/ClO 4 - increases, while that of PPY/PSS decreases. It is concluded that anion transport is primarily responsible for the ionic conductivity of PPY/ClO 4 - , while cation transport dominates in PPY/PSS
