Title: Fly ashes, phosphogypsum waste and biopolymers in composites aided constant magnetic field

Abstract:One of basic issues of the sustainable development is the protection of the natural environment. Very important is the waste recycling and the introducing of green technological processes. The use of Fly Ashes (FA), from coal combustion in power plants presents a very important problem in all countries, in which the energy production is based on this fuel. Fly ashes, owing to the spherical shape of their particles, provide consistency, easy placement and compaction of fresh concrete. Phosphogypsum (PG) is a waste product generated by the chemical industry during phosphoric acid production. The processing of PG waste was carried out in waste-free manner by heat treatment with mixing. Biopolymers (BP) were formed on the basis of epoxy resin and fillers in the form of starch or cellulose waste. The study concerned development of composites based on waste FA, PG and BP. Constant Magnetic Field (CMF) characterised by magnetic induction value B = 1 T was an additional parameter improving, under specific conditions, the physical properties of the resultant composites. With respect to absorbability of the tested samples, as a result of exposure to CMF their weight changed by 7,4 % for composites. With respect to flexural strength of the tested samples is concerned, CMF processing caused a change of 11,9 % for homogeneous materials (cement) and of 7,0 % for composites. With respect to compressive strength of the tested samples, CMF processing caused a change of 6,6 % for homogeneous materials (cement) and of 4,6 % for composites. One can apply new composites as: building materials, substructure of the ground, concealed installation insulation layer and polymer materials.




Title: PRINCIPLES OF CIVILISATIONAL PROGRESS IN THE LIGHT OF PROPHETIC TRADITIONS: A MAQASIDIC PERSPECTIVE

Abstract:Abstract: This paper adopts the higher Shar’iah objectives (Maqasid al-Shar’iah) as a regulated and guiding framework that explores the Prophetic traditions towards establishing the fundamental ethical and intellectual principles required for civilisational progress. To achieve this, it adopts mixed-analytical methods by selecting holistic Prophetic traditions with connotation fundamental to the development of civilisation. The paper then analyses these traditions to bring to the fore its relevance as principles for civilisation




Title: Heating a Thermoelastic Thick Plate by a Pulsed Laser in View of Fractional Order Theory of Thermoelasticity

Abstract:In this work, the upper surface of a thermoelastic thick plate is heated by a pulsed laser beam in the framework of the fractional order theory of thermoelasticity. Both upper and lower faces are assumed to be traction free. The lower surface of the medium is thermally insulated. The problem is solved using Laplace and Hankel transforms. A numerical method was used to obtain inverse Laplace transform. The results of this problem are presented graphically.




Title: THE COMPETITIVENESS OF THE MEXICAN MANUFACTURING SECTOR AND THE IMPACTING MACROECONOMIC VARIABLES.

Abstract:The competitiveness of Mexican manufacturing exports, take on an extremely \nimportant role, as the bridge to prosperity and economic growth. This work aims to \nestablish the impact it has on it, the real exchange rate and other variables, for which \na multifactorial regression model is used, in order to compare the values of the \nvariables mentioned with the values of the international competitiveness index issued \nby the World Economic Forum (WEF). The results indicate that the real exchange rate \nis not a significant variable that is affecting the competitiveness of manufacturing \nexports. However, there is a high dependence of the economic activity of the country \nwith the US economy, which gives the motivation to promote policies to diversify the \nmarkets, increase the productivity and follow the route of deepening the changes and \ntransformations, which lead to the potential growth of the economy.




Title: A CASE OF METASTATIC BREAST CANCER PRESENTING WITH UNEXPECTED PULMONARY DYNAMICS

Abstract:A 34-year-old woman with breast cancer was transferred to the intensive care unit after intubation. Her pulmonary mechanics showed very high airway resistance (Raw) and low dynamic compliance (Cdyn) with normal other parameters. The patient did not have wheezing, chest or lung stiffness and secretion. The tracheal tube was exchanged due to kinging at 16 cm, but Raw and Cdyn did not return to normal limits. Chest computed tomography showed the compression of the right main and left lower posterior bronchus by metastatic masses with no sign of pulmonary infiltration. Abnormally high Raw was attributed to the narrowing of centrally located bronchi and low Cdyn was connected with unequal distribution of airflow across the lung due to patchy compressed large airways.




Title: ENHANCEMENT OF BONDING STRENGTH OF ZIRCONIA TO RESIN CEMENT USING FRACTIONAL CO2 LASER

Abstract:Background: There are limited studies concerning the effects of fractional CO2 laser as a surface treatment of zirconia ceramic. The aim of current study was to enhance the shear bond strength of zirconia ceramic to resin cement using fractional CO2 laser without any damaging effect to the zirconia material. Material and methods: 44 sintered zirconium oxide discs (10 mm in diameter, 2 mm in thickness) were prepared. For the pilot study, 14 zirconia discs were used to determine the spot distance, time interval, and scan no. to select the laser parameters. For the study group, 30 zirconia discs were divided in to three groups (N=10), five pulse durations were used in each groups (0.1, 0.5, 1, 5 and 10 ms). Group A was treated with 10 W power setting, group B with 20 W and group C with 30 W. A luting agent (cement) was bonded to the irradiated zirconia surfaces and cured for 30 seconds. Shear bond strength was evaluated using a universal testing machine. Results: The highest shear bond strength was measured with20 W/0.1 ms pulse duration as (15.5± 0.3 Mpa) and the lowest values with 10 W/10 ms pulse duration as (6.75± 0.2 Mpa). Apparent micromechanical roughening and irregularities were seen in the treated samples and microcracks formation with increased irradiation time and power setting result in higher surface roughness. Conclusion: Fractional CO2 laser is an effective alternative method as it increments the shear strength of zirconia ceramic to resin cement to about 20% more than other surface roughness methods, and the selection of appropriate laser parameter is a critical factor to produce the desired effect without any damage to the zirconia surface.




Title: Comparison of Nutritional Behaviors in Patients with Allergic Rhinitis and Healthy Controls

Abstract:Background: Allergic rhinitis might be seasonal or permanent. In this regard, inappropriate nutrition can contribute to allergy.\nObjectives: The aim of this study was to compare the nutritional behaviors in patients with allergic rhinitis and healthy controls in Qazvin, Iran.\n Methods: This is an analytical, epidemiologic (Case-Control or Causal-Comparative) study. The study was initiated by selecting the patients diagnosed with the allergic rhinitis based on the clinical signs and the diagnosis of the lung super specialist. The group was compared with the patients\' companions as control group (healthy individuals). The data were collected in both groups using the following questionnaires: 1- Demographic Questionnaire (Age, Gender, Education, and Occupation), 2- Checklist of Disease (Type, History, Duration, and Comorbidity), and 3- Nutritional Behavior Questionnaire. The checklist and questionnaire were completed at the clinic. The data were analyzed in SPSS 22. \nResults: A total of 144 patients and 225 companions were selected. Urban life frequency was significantly higher in control than in patient group. Frequency of hereditary diseases was significantly higher in the patient group than the control. No significant difference was found in terms of nutritional behavior frequency (Good, Moderate, Bad) between the patient and control groups. The frequency of snack, saturated oil and vegetable consumption was significantly higher in the control group than in the case group. No significant difference was found between two groups in terms of the frequency of nutritional behaviors (Good, Moderate, Bad) based on gender, BMI, and age group. \nConclusions: According to the results, vegetable, saturated oil, and snack consumption was significantly higher in control group. However, no significant difference was found between two groups in terms of the prevalence of nutritional behaviors (Good, Moderate, Bad).
