Background: The AIDS control and prevention program is one of the PH programs that faces with many ethical challenges. This study aimed to explore the perspectives of HIV/AIDS strategic plan headquarters experts about the relevant ethical considerations.\nMethods: In this qualitative study, focused group discussion method was utilized. After obtaining the license, purposeful introduction of experts, and previous coordination for the purpose, the subject and time of the meeting, two meeting sessions were held with the participation of six ministry and university experts of HIV/AIDS control program. After frequent review of the data and using content analysis, main themes and subthemes were categorized. Recording and writing the experiences of participants were done accurately and impartially. In order to findings transformability to similar situations, the data were checked by three other experts.\nResults: The participants agreed that HIV/AIDS control requires focusing on prevention, treatment, care and support services, and considering the general population and all vulnerable groups including pregnant mothers and children. In this study, five main themes were emerged: training and informing, confidentiality, stigma and discrimination, support and empowerment, and accountability. \nConclusion: Regarding the participants mention to some of the moral norms in the HIV/AIDS strategic plan, training of moral norms in PH programs with a special look to AIDS, and using a practical framework for systematic ethical evaluation of the program are recommended in order to ensure the achievement of program goals.

We study the global dynamics of following type systems of difference equations:\n \nwhere and initial values are non-negative real numbers. Several numerical simulations are provided to support obtained results.

Portico as elements of high value in the exterior of the building will be the subject of my study. Their treatment as architectural and decorative values will be realized as part of churches with inscribed cross. The porch is a long and narrow exonarthex. Often it is closed with columns or arcades. Situated at the entrance to the church and traverses across its width.

The review paper illustrates traditional medicine aspects, phytochemistry and pharmacology studies of Mandragora species (Mandrake) from Solanaceae family. Iranian traditional medicine (ITM) uses and therapeutically index and scales, pharmacologically active compounds and their biological activities of Mandrake have been obtained from textbooks and related articles. \nTemperament is a principle in ITM and dependent to four elements which are Fire, Water, air and water. ITM physicians were cured patients using disease and drug temperaments equivalency. Mandrake is an herb that has been widely used in ITM. Root of Mandrake as main medicinal organ has cold and dry temperament. The plant has been used in ITM for skin disorder and digestive, nervous and skeletal systems diseases and abortion prevention. The major phytochemical compounds are tropane alkaloids and Coumarins. In addition, the main biological activities of Mandrake are anesthetics, hypnotic, antipsychotic, immunomodulatory and anti-diabetic effects.

In this paper a new method for automatic text classification is proposed. This system consists of two phases, text processing and text classification. To extract the features we have usedin the first phase several indexing criteria like bigram, trigam and quadgram. Then in the second phase the machine learning algorithm W-SMO was applied to teach the algorithm. Macro-F_1 and Micro-F_1 are calculated for different indexing methods to evaluate and compare results of two criteria i.e. accuracy and recall. Results of the tests done on 7676 standard text documents of Reuters indicated that our proposed method has the best efficiency to algorithms W-j48, Naïve Bayes, K-NN and Decision Tree.

The rapid growth of demand for cloud computing resources by massive data centers, have increased the rate of energy consumption. One of the solutions for reducing energy consumption is relocation of services. This article has presented an algorithm for integration of related services which are called collaborative services through live migration. Integration of these collaborative services would decrease their communicational expenses to zero and would also decrease their energy consumption. The recommended algorithm by immigrating services on a priority basis, from hosts with very high or very low workloads (in a way that would increase energy consumption) to hosts with collaborative services, would increase the use of existing resources and decrease energy consumption. The recommended algorithm has been simulated using Cloudsim 3 software and parameters of reducing energy consumption, number of migrations and the number of hosts that were turned off were compared and evaluated through policies of minimum utilization, random choice policy and minimum migration time; results showed that the recommended algorithm had a desirable function.

Alkylphenols (APs) received great attention in the past decade because they were on the priority hazardous substances list. The kinetics of a lab-scale moving bed biofilm reactor (MBBR) that was fed with synthetic wastewater containing 4-NonylPhenol (4-NP) and 4-tert-OctylPhenol (4-t-OP) was investigated in this paper. The MBBR reactor was evaluated under different Aps, organic loading rates, and hydraulic retention times (HRT). The substrate removal rate was predicted with First order, Second order, Stover–Kincannon and the Monod substrate removal models.\n4-NP and 4-t-OP pollutants were removed in the different percentages of 87.1% to 99.9% and 83.2% to 99.9%, respectively. Biokinetic parameters like Y, KS, k, µmax and kd that would be favourable to design an MBBR were evaluated. Based on the results, the second-order (Grau), Stover–Kincannon and Monod models were observed to be the most suitable for this reactor. These models showed high correlation coefficients of about 99.6%, 99.1% and 92.9%, respectively. Consequently, these models could be utilized in anticipating the performance and design of MBBR reactors.
