Industrial waters are discharges classified as hazardous because of their quantity, concentration or the physical and chemical properties of their constituents (turbidity, heavy metals, organic or phosphorus compounds) that threaten human health and the environment. Among the hazardous industrial waters, we distinguish industrial wastewater. These industrial discharges contain various products in insoluble or soluble form of mineral and/or organic origin, more or less biodegradable and sometimes toxic even in very low concentrations.
In this work, the coagulation-flocculation process was used as a new technology approach for the treatment of this type of rejection. In this study, the jar test was used to determine the optimal conditions of the coagulation-flocculation process using mimosa tannins as natural coagulant by applying a response surface methodology (RSM) based on the bencken box design (BBD) of three levels with three factors (PH, coagulant dosage and setting time) . The BBD is successfully demonstrated to effectively determine the optimized parameters, where 97% of the water turbidity was removed with an initial value of 201 NTU for the optimal conditions of pH (5), coagulant dosage (10 mL/L), settling time (60 min). To evaluate the performance of optimization and modeling of coagulation flocculation process, the coefficients of determinations R2 and R2 adjusted were used, the results obtained clearly show that the R2 (97.20%) and R2 adjusted (92.16%) obtained confirm the validity of this mathematical model.

PT Pertamina Patra Niaga West Java Region is an investment implementation function based on the budget written in RKAP of each period. The investments carried out are spread in each work location at Jakarta, Banten and West Java. Fuel Terminal Tanjung Gerem is one of the Main Transit Fuel Terminals in the Pertamina Patra Niaga – West Java Region. Located near seafront made Fuel Terminal Tanjung Gerem have high corrotion rate more than 0,05 mm/year. Based on the pareto diagram analysis, the main cause for the high operating cost budget year 2021 of Fuel Terminal Tanjung Gerem was the High Maintenance Cost of Concrete Structure of Jetty, Fuel Tank and Piping due to high corrotion rate. Maintenance cost especially for retrofit activity usually use common fiber reinforced polymer. The weakness of common fiber reinforced polymer cannot strengthen the structural strength of existing facilities. To overcome this problem, Mamboo3 (Material Admixture Bamboo Fiber with Honeycomb Configuration MOR 3) is determined as alternative solution of Common Fiber Reinforced Polymer. By applying Mambo3, the Quality of Structure (Concrete and Metal) after retrofit have Tensile strength min 564 Mpa and yield strength min 734 Mpa (better than quality of new facilities). In addition lifetime of existing facilities increased to 8 years and reducing maintenance cost 30,2% (USD 51,77 / m2).
This innovation has been endorsed by an external party, PT Surveyor Indonesia, PT. Sucofindo and Institut Teknologi Bandung. Replication has been carried out for the Fuel Terminal PT. Pertamina Patra Niaga – West Java Region and Central Java Region.
Petrography and Textural Characteristics of Late Cretaceous Orbicular Gabbro West of Elazığ (Turkey)
Authors: Ertürk Mehmet Ali , Sar Abdullah 
Published: May 2023

The lithological units outcropping in the study area are located in the Southeast Anatolian Orogenic Belt, one of the most important parts of the Alpine-Himalayan Orogenic Belt. The units of the study area are Middle Devonian-Lower Cretaceous Keban Metamorphics, Upper Cretaceous Elazığ Magmatics, Upper Maastrichtian-Paleocene Seske Formation, Middle Eocene-Upper Oligocene Kırkgeçit Formation and Quaternary cover units. The study area crops out in a local area within the Hısırık creek in the north of Sarıgül village of Baskil county, which is located in the west of Elazig province in Southeast Turkey. Elazig magmatic complex contains plutonic and sub-volcanic rocks, mainly felsic and mafic compositions. Plutonic rocks with felsic composition include granite, granodiorite, tonalite and quartz monzonites, while sub-volcanic rocks include aplite. Plutonic rocks with mafic composition are represented by diorite, quartz diorite, gabbro and orbicular gabbro, and sub-volcanic rocks are represented by diabase and diorite porphyries. The orbicular gabbros contain orbicles ranging in size from 1 cm to 15 cm, formed by repetitive concentric circles of fine and coarse grains. All these orbicles consist of concentric circles that show magmatic textures both in macro specimens and under the microscope. Orbicular circles were formed by the crystallisation of basic magma in the form of a circular texture by conventional repetition as a result of adding a basic new magma that was later included in the magma chamber during the crystallisation of basic magma. Mineralogical and petrographic features suggest that the orbicular gabbro is part of mafic igneous enclaves within intrusive mafic rocks.

Published: May 2023

Background: Bell's palsy is a disease involving the seventh cranial nerve, which regulates facial muscle action. Facial muscles get paralyzed when this nerve is damaged. Objective: The primary objective of this researcher is to find out the effect of High Intensity Laser Therapy (HILT) on facial muscle function in patients with chronic bell’s palsy. Subjects and Methods: Twenty patients diagnosed with chronic Bell’s palsy and twenty healthy individuals of both sexes were recruited, falling within the age group of 20-40 years. Participants were assigned into two groups. Group A (Healthy individuals) and Group B (Bell’s palsy patients). Group A participants were intervened with Nd: YAG High intensity LASER, one session/week for total of 4 sessions. Facial angle measurement was done in resting state and in contracted positions of the respective muscles on both the sides of face. These angles were analyzed using the Auto-CAD program. Results: A significant increase in facial angle was observed in raising eye brow, light eye closing, smiling, kissing, and blowing on the non-affected side and a significant decrease of these angles on the affected side following treatment (p<0.05). Comparison between non-affected sides versus affected side showed significant differences in measured angles except for smiling and kissing angles. Conclusion: High-Intensity Laser Therapy (HILT) improved the function of the facial muscles in patients with chronic Bell's palsy.

Background: Lumbar disc herniation (LDH) is one of the most common causes of medical consultation in the orthopedic clinics. LDH is believed to be the root cause of 60-80 percent of low back pain cases over a lifetime. Objective: The current study aims to evaluate the effectiveness of different dissimilar manual therapy techniques (Mulligan’s spinal mobilization with leg movement versus McKenzie technique) in patients with lumbar disc herniation. Design: The present study is a randomized control trial in which 45 individuals diagnosed with LDH were recruited as the participants of the study (mean age 48.54 ± 5.8 years). The participants were randomly allocated into three groups, with n=15 in each group. Intervention: Participants of the group A (Experimental group A) received Mulligan spinal mobilization with leg movement and T.E.N.S. (Transcutaneous Electrical Nerve Stimulation). Group B (Experimental group B) participants received McKenzie technique. Group C (control group) participants only received T.E.N.S. for four weeks. All patients in the three groups received 3 sessions each week. Pain, functional disability, and the H reflex were the primary outcome measures. The visual analogue scale (VAS) was used to assess pain, the Oswestry disability scale was used to assess functional disability, and electromyography was used to assess the H reflex. Results: Significant improvements were seen in the participants of group A, with reduction in the intensity and severity of pain, decreased level of functional disability and improvement in the H reflex, in comparison with other groups. Conclusion: Spinal mobilization with leg movement was more effective than McKenzie technique and TENS to reduce pain and functional disability, and to improve the H reflex, in individuals suffering from lumbar disc herniation.

There is a piece of growing evidence that the sports industry has reached the level of optimum financial stability, but on the other side it has also created an environment for the emergence of specific corruption in the field of sports in the form of match-fixing and illegal betting. The corruption has crossed the roads to public administration and has spread into new areas of society. Corruption in sports involves any illegal, immoral, or unethical activity that attempts to deliberately distort the integrity of any sport thereby affecting or manipulating the outcome of the sports events. As a result, "sports corruption" today is large, global, and organized. The present study was conducted to highlight the rapidly expanding corruption issues in various spheres of public relations. This research has notified the lack of evidence in the field of sports at national and international levels regarding the issues of improving legal and organizational measures to prevent corruption and maintain fairness in sports. The study of scientific positions of experts on this issue in the comparative legal aspect will expand the theoretical provisions of the sciences of criminal law, to develop recommendations for improving existing legislation and law enforcement practice.

Published: May 2023

Building performance has significant impact on humans’ life and ecology as buildings account for 39% of total greenhouse gas emissions and consume about 40% of total global energy consumption. Smart building control is one of the key points to archive high energy efficiency. Each year, the complexity of building state control grows due to the increase in the number of controlled elements that are used to achieve better indoor climate. Therefore, in the manual analysis and implementation of the building control program, an error can easily appear due to the human factor. Artificial intelligence (AI) algorithms could be used as an alternative solution as they could evaluate building dynamics independently. One of strategies for automatic building control adaptation to its dynamic is model based predictive control where neural network is used for different control strategies evaluation. Performance of such control technique is highly dependent on control strategies evaluation accuracy. To achieve top accuracy, several hyperparameters of neural network could be tuned as well as data set for specific construction must be prepared. Preparation of data set could be a problem as random control of building for generation of dataset could be not unacceptable for building users as well as it could damage construction.In this paper authors process optimization of experimental building heating system control algorithm to achieve smaller fluctuations of temperature indoors. For dataset generation were used several data from weather station as well as heating system parameters and temperature indoors while building was controlled by thermostat with build in PID regulation. For evaluation of building dynamics were used temporal convolutional neural network. To achieve high accuracy results of control strategies evaluation, several hyperparameters of neural network were tested. Finally resulting model were tested on physical building. Results indicate that in some cases developed control model could prevent temperature fluctuations which could be caused by limits of heating system power.
