This work also investigated the causes and factors affecting C&D waste to understand the actual waste management activities and proposed strategies to minimize the waste generated at the local level. This study estimated C&D waste generation rates based on data collected from five construction projects and two demolition projects in Kuwait. In addition, a questionnaire survey was conducted to evaluate the causes of C&D waste generation. The results showed that the average C&D waste quantities generated by construction activities were 49.5 kg/m2 for public/commercial building projects and 35 kg/m2 for residential projects. At the same time, public/commercial construction, residential construction, and demolition works generated 1.480 ton/m2, 0.0495 ton/m2, and 0.035 ton/m2, respectively. The average composition of C&D wast...

This study is about finding economic optimization scenarios for Iraq power mix, as the country is in dire need to minimize its power generation costs and finding the ultimate power mix structure that can help in developing the country for the better. Mean Variance Approach (MVA) is used to optimize the national power mix. It considers various costs that are involved in the power generation and the associated risks of using a particular power generation technology. The three main generation power technologies that were taken into account are gas turbines, thermal and diesel power stations in addition to the electricity imported and the generated electricity by the independent power producers (IPPs). The study proposes an optimization scenario balancing between the involved costs and risks associated with the power mix. The optimal scenario is to use around 47% gas turbines, 14% thermal, 0.04% diesel, 2% hydro and 33% IPPs.

Phonological and morphological awareness are shown to be predictors of hearing and deaf children'... more Phonological and morphological awareness are shown to be predictors of hearing and deaf children's literacy achievements in various languages, and Arabic is assumed to be no different. However, this might not be the case for two reasons. Firstly, the linguistic context of the Arab world is characterised by diglossia, i.e. the use of two different varieties of the same language in different settings. Hearing and orally educated deaf children will therefore encounter the vernacular variety of Arabic outside school, but are introduced to literacy in the more prestigious variety of Standard Arabic during instruction in school. Secondly, Arabic orthography has two forms: a fully vowelised script, which is typically taught in the first two years of school, and a non-vowelised script, which is the form of the written language widely used in society. This study specifically aims to investigate whether phonological and morphological awareness are independent predictors of the emergent literacy achievement of hearing and orally educated deaf Kuwaiti children. This is in addition to the question of whether children's awareness of the two language forms, i.e. their dialect awareness, contributes to their literacy achievement and to their levels of phonological and morphological awareness. This investigation was carried out longitudinally through a number of phonological, morphological and dialect awareness measures utilised as predictors of literacy outcome skills of word reading, word spelling, pseudo-word decoding and reading comprehension. Variances of age and general cognitive ability were controlled for throughout all the analyses undertaken. The results for the first target group of hearing children (N = 78, aged 6; 2 years) indicated a significant superiority of phonological awareness as the predominant predictor of all literacy skills across grade levels one and two. Morphological awareness was a predictor of firstgraders' spelling ability, and was subsequently implemented to predict all the literacy skills of second-graders. Dialect awareness was a predictor of the word reading and reading comprehension ability only for second-graders, and its mediational effect was revealed when it was seen to significantly reduce the effect of phonological and morphological awareness on second-graders' reading skills after being examined as a control measure. The results for the second target group of orally educated deaf children (N = 34, aged 7; 6 years) indicated that phonological, morphological and dialect awareness were varyingly significant independent predictors of the subjects' literacy skills. A mediational effect of dialect awareness on the predictive link between morphological awareness and word spelling outcome was also evident. Although the prediction association between literacy predictor and outcome measures was mostly consistent and similar across both groups, exceptions in the predictive pattern revealed that the deaf children were at a disadvantage in developing language awareness skills that facilitate efficient mapping of speech into the written form. These findings are discussed in terms of language-general and language-specific properties. The outcomes offered by the current study cannot imply a cause-and-effect association, but allow for constructive identification of literacy predictors and assist in clarifying possible implications for children's literacy capabilities. As the strengths and needs of the examined groups have been clearly recognised, future investigations of causal and mediational analyses will validate the current findings about the Arabic diglossic phenomenon, and additionally specify an appropriate response in terms of practical educational plans. Although standard written Arabic and spoken Arabic dialects are all derived from classical Arabic, all the spoken dialects differ from the written form. The extent of variation between the standard form and the spoken form is seen in the domains of phonology, morphology, semantics and syntax. As the current study is concerned with Kuwaiti Arabic, the spoken variety used in the State of Kuwait, and standard Arabic, the lingua franca used in learning and education across the Arab world, the main linguistic variances between both forms are reviewed. These are presented in terms of the phonological, morphological and syntactic systems, as well as the lexical choices made by speakers (

The upper one is permeable and below one is stretching and hot. The distance between two plates changes with time. The final equations were solved via MAPLE, and to analyze the impact of active factors, two significant functions were calculated. Two new formulas for Nu and En were suggested based on numerical data and outputs were summarized as contours and plots. Nu has various behaviors with change of α. Results depict that Nu declines about 21.29% with rise of α from 0 to 2. Positive impact of R on Nu is more significant for lower α and 37.44% augmentations were reported when R augments. Thinner boundary layer with rise of m results in higher Nu and 437% augmentation can be seen with rise of m from 0 to 3. With rise of particle interaction with rise of φ, temperature augments and greater heat transfer rate appears. Inclusion of nanopowders leads to augmentation in Nu about 3.54%. At first Nu rises with rise of R augments and then reduces, while opposite trend was observed for α. Nu for α = 2 is 1.13 times greater than that of α = 0 when R = 5, m = 1. To reach greater influence of nanoparticle dispersion, the lower values of m should be selected. As m augments, Nu reduces about 57.58% which means that a higher value of m leads to lower conduction mode.

The transportation of nanopowder was controlled by magnetic force and insert of porous media boosts the cooling rate. Such zone needs special model to involve the impact of porous media and in this paper, non-Darcy technique was utilized. Low fraction of hybrid nanomaterial leads to good accuracy of homogeneous model and empirical correlations have been employed to forecast the features of operating fluid. Entropy generation was studied to find the influence of each term on irreversibility of unit. Also, two significant functions were calculated, namely, Be and Nu. Influences of Ra, Da and Ha on contours plots were reported in outputs. As Ra augments, the convection becomes stronger and augmentation of [Formula: see text] proves this fact. Also, temperature of elliptic surface declines about 48% with intensifying Ra. Temperature of elliptic surface augments about 34.6% with augment o...
