Estimating Factors Affecting the Sustainable Environmental Development

An issue of Sustainable Environmental Development has occupied a wide range of interests of researchers and economists in some developing countries. The environmental issues are tightly linked to the development policies and the environmental grasp is no longer a matter of social welfare, but rather is a matter of economical; social and human dimensions. The research displays a concept of sustainable development, then estimating the impact of two variables: the economic development and the bio-ecological system on the sustainable development of some countries, including Iraq according to the fact that “increasing demand for foods and products in these countries has led them towards the intensive usage of natural resources which has, eventually, impairs the rates of development and contributes in the deterioration of bio-ecological system and impairs the sustainable development. The results of the analysis showed that the environmental ecosystem variable has a greater impact on sustainable environmental development than the economic development variable, which means that the environmental situation of some countries, especially the developing countries, continue to deteriorate, requiring all specialists and governments to make efforts to preserve the ecosystem for future generations

Effect of sodium chloride concentration on the functional properties of selectec Legume flours

Providing safe, nutritious, and wholesome food for poor and undernourished populations has been a major challenge for developing countries. This has led to the necessity of assembling complete food composition tables, yielding information about the traditional foods and on the functional properties of the plant foods that are consumed regularly in the developing countries. Sodium Chloride (NaCl) is the common salt used at household and industry levels to improve palatability of processed foods. Therefore, the main aim of the present study was to investigate the influence of different concentrations of NaCl on the functional properties of selected legume flours. The effect of increasing concentration of NaCl on the protein solubility, emulsifying and foaming properties of white bean, pigeon pea, cowpea and hyacinth bean were studied. The results revealed that the protein solubility of pigeon pea, cowpea and white bean flours significantly increased by increasing salt concentration and reached a maximum at 0.4 M NaCl (for pigeon pea and cowpea flours) and 0.6 M for white bean flour and then gradually decreased at higher salt concentration. The protein solubility profile of hyacinth bean fluctuated with the salt concentration, with the highest solubility at 0.6 M NaCl and lowest solubility at 0.4M NaCl. With the exception of white bean, the maximum emulsifying activity of all selected legume flours was found at 0.4 M NaCl whereas that of white bean was found at 0.2 M NaCl. Generally, with increasing salt concentration, the emulsifying activity slightly decreased for the legume flours, except for cowpea which fluctuated. Addition of NaCl significantly decreased the emulsion stability and foaming capacity of the four of selected legume with the maximum improvement being observed at 0.2 M NaCl, and then decreasing gradually at higher salt concentration. Significant improvement of foaming stability was observed when salt concentration increased. Based on the results of the present study the selected legume flour demonstrated good functional properties following the addition of NaCl, which makes these legume flours potential ingredients for application in salt containing foods.Keywords: functional properties, Legumes, Protein solubilityAfrican Journal of Food, Agriculture, Nutrition and Development, Volume 12 No.

Optimization algorithms for transportation problems with stochastic demand

The purpose of this paper is to solve the stochastic demand for the unbalanced transport problem using heuristic algorithms to obtain the optimum solution, by minimizing the costs of transporting the gasoline product for the Oil Products Distribution Company of the Iraqi Ministry of Oil. The most important conclusions that were reached are the results prove the possibility of solving the random transportation problem when the demand is uncertain by the stochastic programming model. The most obvious finding to emerge from this work is that the genetic algorithm was able to address the problems of unbalanced transport, And the possibility of applying the model approved by the oil products distribution company in the Iraqi Ministry of Oil to minimize the total costs, Where the approved model was able to minimize the total costs by 25%. A future study investigating optimization heuristic with stochastics demand would be very interesting

Bitcoin Prediction with a hybrid model

. In recent years, Bitcoin has become the most widely used blockchain platform in business and finance. The goal of this work is to find a viable prediction model that incorporates and perhaps improves on a combination of available models. Among the techniques utilized in this paper are exponential smoothing, ARIMA, artificial neural networks (ANNs) models, and prediction combination models. The study's most obvious discovery is that artificial intelligence models improve the results of compound prediction models. The second key discovery was that a strong combination forecasting model that responds to the multiple fluctuations that occur in the bitcoin time series and Error improvement should be used. Based on the results, the prediction accuracy criterion and matching curve-fitting in this work demonstrated that if the residuals of the revised model are white noise, the forecasts are unbiased. Future work investigating robust hybrid model forecasting using fuzzy neural networks would be very interesting

Fiberoptic bronchoscopic cryo-ablation of central bronchial lung cancer

AbstractBackgroundRadiotherapy and chemotherapy are the standard palliative treatments in patients with inoperable carcinoma of the lung present with obstruction of the central airway but have limited effectiveness in reopening obstructed airways. Cryosurgery is one of the several techniques that can be used to reopen an obstructed tracheobronchial lumen.ObjectiveThe aim of this study was to evaluate safety and clinical efficacy of flexible cryoprobe as an important option to treat the patients with inoperable obstructive central bronchial lung tumors.Patients and methodsThis study was conducted on 38 patients with central endobronchial malignant tumor. A flexible cryoprobe was used during flexible bronchoscopy. The endobronchial tumors and symptoms were assessed 2 and 6weeks after cryotherapy.ResultsAfter 6weeks, the endobronchial lesions were completely removed in 32/38 patients (∼85%), partly removed in 4/38 patients (∼10%), and could not be removed in 2/38 patients (∼5%), with a symptomatic improvement in dyspnea, cough and hemoptysis 78%, 63.0%, 85% after 2weeks and up to 89%, 84.0%, 100% after 6weeks respectively.ConclusionCryotherapy using fiberoptic bronchoscopy is a safe with a high efficacy technique in treating endobronchial malignant obstructive lesions

New Fast Transform for Orthogonal Frequency Division Multiplexing

In this paper, a new fast and low complexity transform is introduced for orthogonal frequency division multiplexing (OFDM) wireless systems. The new transform combines the effects of fast complex-Walsh-Hadamard transform (CHT) and the fast Fourier transform (FFT) into a single unitary transform named in this paper as the complex transition transform (CTT). The development of a new algorithm for fast calculation of the CT transform called FCT is found to have all the desirable properties such as in-place computation, simple indexing scheme and considerably lower arithmetic complexity than existing algorithms. Furthermore, a new OFDM system using the FCT algorithm is introduced and its performance has been evaluated. The proposed CT-OFDM achieves a noticeable reduction in peak-to-average-power-ratio (PAPR) and a significant improvement in the bit-error-rate (BER) performance compared with the conventional OFDM.Comment: 12 pages, 8 figures, 1 tabl
