Construction of (n+ 1) -dimensional dual-mode nonlinear equations: multiple shock wave solutions for (3 + 1) -dimensional dual-mode Gardner-type and KdV-type

The goal of this study is to offer an exclusive functional conversion to produce (n+ 1) -dimensional dual-mode nonlinear equations. This transformation has been implemented and new (3 + 1) -dimensional dual-mode Gradner-type and KdV-type have been established. Finally, the simplified bilinear method is used to tell the necessary conditions on these new models to have multiple singular-solitons. - 2019, The Author(s).This work is financially supported by UKM Grant: DIP-2017-011 and Ministry of Education Malaysia Grant FRGS/1/2017/STG06/UKM/01/1.Scopu

The Linguistic Variants of Allah Expressions in Jordanian Arabic

This paper is bifocal. Its first purpose is to shed some light on the widespread use of Allah expressions in Jordanian Arabic as well as other dialects of Arabic. These are expressions that are used repeatedly by Muslims on a daily manner in different venues reflecting their belief that Allah alone is the One who has influence over every aspect of their lives. The second purpose is to draw the attention to some expressions containing the word Allah. In some of these expressions, the word Allah has disappeared as a result of being blended into other particles as in the case of jalla meaning “let” and jaallah meaning “barley”. However, in other expression, the word Allah is still witnessed but used in totally new meanings as in expressing astonishment and seeking protection and guidance

A safety-centric change management framework by tailoring agile and V-Model processes

Safety critical systems are evolutionary and subject to preventive, perfective, corrective or adaptive changes during their lifecycle. Changes to any part of those systems can undermine the confidence in safety since changes can refute articulated claims about safety or challenge the supporting evidence on which this confidence relies. Changes to the software components are no exception. In order to maintain the confidence in the safety performance, developers must update their system and its safety case. Agile methodologies are known to embrace changes to software where agilists strive to manage changes, not to prevent them. In this paper, we introduce a novel framework in which we tailor a hybrid process of agile software development and the traditional V-model. The tailored process aims to facilitate the accommodation of non-structural changes to the software parts of safety critical systems. We illustrate our framework in the context of ISO 26262 safety standard

Breeding Potential of Durum Wheat Landraces from Jordan Ill. Rate and Duration of Grain Fill

Grain fill of durum wheat coincides with terminal drought and high temperature stress in the Mediterranean region. Genotypic variation for rate and duration of grain fill was studies in 250 landrace durum wheat genotypes collected in Jordan. A quadratic polynomial was used to describe the relationship between kernel weight and accumulated growing-degree-days from anthesis to maturity. Fitted curves were employed to estimate rate and duration of grain fill. Genotypic differences were found for both traits. Genotypes with high grain filling rate and high kernel weight were identified. Based on grain yield per spike, spikelet fertility, 1000-kernel weight, rate and duration of grain fill, four clusters were identified in this germplasm collection. Correlations between these traits were inconsistent across these clusters, however, rate and duration of grain fill were not correlated across clusters, suggesting that high rate and short duration of grain fill can be combined in one genotype. Canonical discriminant analysis confirmed univariate analysis of variance and resulted in 95% correct classification of genotypes

Breeding Potential of Durum Wheat Landraces from Jordan IV. High Molecular Weight Glutenin Subunit Variation.

Variation in high molecular weight glutenin subunit composition among 177 durum wheat genotypes, derived from a collection of durum wheat landraces from Jordan, was investigated using one-dimensional sqdium dodecyl sulphate polyacrylamide gel electrophoresis. A total of 22 alleles, in addition to the null allele, Glu-A I c, were identified; three and seven novel variants were identified at the Glu-A I and Glu-B I loci, respectively. The null allele, Glu-A I c, had the highest (7 6. I%) frequency, followed by Glu-B I b (34. 7% ). Two loci at the Glu-B I locus were lacking, these were Glu-B I c and Glu-B I i. Glu-A I b was present with low (6.7%) frequency in this collection, however, it might have a positive effect on gluten strength of the end products of durum wheat. Polymorphism (He) at the Glu-A I and Glu-B I loci averaged 0.261 0.04 and 0.7330.02, respectively. He for Glu-A I was negatively (r=-0.467; P) correlated, while He for Glu-B I was positively (r=0.615; P), correlated with altitude of collection site. However, both He estimates were positively and significantly correlated with rainfall quotient

The Effectiveness of a Sports Program in Developing the Social Skills of Deaf Individuals in a Jordanian Sample

In this paper, we examine the impact of a sports program on the social skills of deaf individuals. The sample consisted of 60 deaf individuals in Zarqa Governorate, with 40 individuals randomly selected for the study. The sample was divided into an experimental group of 20 individuals and a control group of 20 individuals. The effectiveness of the sports program in developing social skills was evaluated using a scale specifically designed for deaf individuals. The results, analyzed using statistical methods, demonstrated that the sports program effectively improved the social skills of the deaf individuals. These findings were consistent with previous studies, and several recommendations were made to aid in the integration of deaf individuals into society

BIOPHYSICAL CONSTRAINTS AND ECOLOGICAL COMPATIBILITIES OF DIVERSE AGROECOSYSTEMS

International audienceA diagnostic approach based on multi-scale integrated analysis and model simulations was employed to identify specific or common biophysical constraints, technological changes and ecological compatibilities of the diverse subsistence (SUB) and organic (ORG) agro-ecosystems in the Fertile Crescent (FC) of West Asia and the organic and conventional (CNV) agro-ecosystem in the Northern Corn Belt (NCB) and Northern Great Plains (NGP) of the U.S. For each agro-ecosystem, soil carbon, total yield, temporal yield variance and yield coefficient of variation per crop rotation were used as sustainability indicators. Thresholds of technologies necessary for the proper functioning and flow of agro-ecosystem services were identified under the most-likely IPCC-projected climate change scenarios for the next 30 years. The carbon budgets of agro-ecosystems were largely related to the choice of crops, crop sequence, and length of the crop rotation, and were influenced by external inputs, tillage system and removal of crop residues. Carbon depletion is expected to be less in organic and subsistence agro-ecosystems when nitrogen-fixing legumes are included in more diverse crop rotations and when crop residues are incorporated into the soil. Potential nutrients loss to the environment was significantly larger in conventional systems, and nutrients are expected to be depleted over time in subsistence- faster than in organically-managed soils. Optimal and sustainable agricultural intensification is feasible through agroecosystem diversification and the proper integration of genetic and natural resources management. In all agroecosystems, for more diverse rotations to be adopted at a large scale, there needs to be large and easily accessible markets for the additional product

Characterization of surface proteins of Cronobacter muytjensii using monoclonal antibodies and MALDI-TOF Mass spectrometry

<p>Abstract</p> <p>Background</p> <p><it>Cronobacter </it>spp. is a newly emerging pathogen that causes meningitis in infants and other diseases in elderly and immunocompromised individuals. This study was undertaken to investigate surface antigenic determinants in <it>Cronobacter </it>spp. using monoclonal antibodies (MAbs) and MALDI-TOF Mass spectrometry.</p> <p>Results</p> <p>Spleenocytes from mice that were immunized with heat-killed (20 min, 80°C) <it>Cronobacter </it>cells were fused with SP2 myeloma cells. Five desirable MAbs (A1, B5, 2C2, C5 and A4) were selected. MAbs A1, B5, 2C2 and C5 were of IgG2a isotype while A4 was an IgM. Specificity of the MAbs was determined by using immunoblotting with outer membrane protein preparations (OMPs) extracted from 12 <it>Cronobacter </it>and 6 non-<it>Cronobacter </it>bacteria. All MAbs recognized proteins with molecular weight ranging between 36 and 49 kDa except for one isolate (44) in which no OMPs were detected. In addition, MAbs recognized two bands (38-41 kDa) in four of the non-<it>Cronobacter </it>bacteria. Most of the proteins recognized by the MAbs were identified by MALDI-TOF peptide sequencing and appeared to be heterogeneous with the identities of some of them are still unknown. All MAbs recognized the same epitope as determined by an additive Index ELISA with their epitopes appeared to be conformational rather than sequential. Further, none of the MAbs recognized purified LPS from <it>Cronobacter </it>spp. Specificity of the MAbs toward OMPs was further confirmed by transmission electron microscopy.</p> <p>Conclusions</p> <p>Results obtained in this study highlight the immunological cross-reactivity among <it>Cronobacter </it>OMPs and their <it>Enterobacteriaceae </it>counterparts. Nevertheless, the identity of the identified proteins appeared to be different as inferred from the MALDI-TOF sequencing and identification.</p

Influence of sonication and in vitro evaluation of nifedipine self‑nanoemulsifying drug delivery system

In order to develop a self-nanoemulsifying system, three components, olive oil, Tween 80, and Capmul, were used to construct a ternary phase diagram that helped to find the optimum formulation, which was loaded with nifedipine. The effect of sonication on drug loading was also evaluated. After that, measurement of the droplet size, size distribution, zeta potential, and scanning electron microscopy were conducted for evaluation and characterisation of the formulations. The phase diagram of four formulations showed nanosizes below 200 nm; however, only one was selected to be loaded with nifedipine. The selected formulation had the lowest droplet size of 98 nm and size distribution 0.192, and was composed of 48% Tween 80, 32% Capmul, and 20% olive oil. The nifedipine self-nanoemulsifying drug delivery system (SNEDDS) showed a significant change in the particle size (97 nm) and size distribution (0.257) after sonication. Its zeta potential was -32.3 mV indicating good stability. The SEM photographs of nifedipine showed particles with spherical shape and smooth surface. Finally, a self-nanoemulsifying formulation containing nifedipine, loaded in olive oil, was successfully prepared by mixing the oil with various types of surfactants and co-surfactants. A significant nifedipine self-nanoemulsifying system was developed and significantly improved accordingly
