Particle Swarm Optimization Method Combined with off Policy Reinforcement Learning Algorithm for the Discovery of High Utility Itemset
Authors: Logeswaran K. , Suresh P. , Anandamurugan S. 
Published: March 2023

Mining of High Utility Itemset (HUI) is an area of high importance in data mining that involves numerous methodologies for addressing it effectively. When the diversity of items and size of an item is quite vast in the given dataset, then the problem search space that needs to be solved by conventional exact approaches to High Utility Itemset Mining (HUIM) also increases in terms of exponential. This factual issue has made the researchers to choose alternate yet efficient approaches based on Evolutionary Computation (EC) to solve the HUIM problem. Particle Swarm Optimization (PSO) is an EC-based approach that has drawn the attention of many researchers to unravel different NP-Hard problems in real-time. Variants of PSO techniques have been established in recent years to increase the efficiency of the HUIs mining process. In PSO, the Minimization of execution time and generation of reasonable decent solutions were greatly influenced by the PSO control parameters namely Acceleration Coefficient and and Inertia Weight. The proposed approach is called Adaptive Particle Swarm Optimization using Reinforcement Learning with Off Policy (APSO-RLOFF), which employs the Reinforcement Learning (RL) concept to achieve the adaptive online calibration of PSO control and, in turn, to increase the performance of PSO. The state-of-the-art RL approach called the Q-Learning algorithm is employed in the APSO-RLOFF approach. In RL, state-action utility values are estimated during each episode using Q-Learning. Extensive tests are carried out on four benchmark datasets to evaluate the performance of the suggested technique. An exact approach called HUP-Miner and three EC-based approaches, namely HUPEUMU-GRAM, HUIM-BPSO, and AGA_RLOFF, are used to relate the performance of the anticipated approach. From the outcome, it is inferred that the performance metrics of APSO-RLOFF, namely no of discovered HUIs and execution time, outstrip the previously considered EC computations.

The purpose of this study is to complete as an example the fermentation conditions allowing the production of Saccharomyces cerevisiae yeast biomass in large quantities using the juice as the same carbon source. Determination of the best of five factors affects the production of dry biomass by baker’s yeast. The optimal value of the five factors affecting the process of biomass production by the baker’s sourdough was determined. The experimental design was performed using CCD (Central Composite Experimental Design), and the response surface methodology method was used to determine the best possible amount of production of yeast and has reached (41.44 g/L) after 12 hours of fermentation, under the following optimal conditions (temperature (30.11°С), pH (4.75), sugar concentration (158.36 g/L), the ratio of carbon to nitrogen (an essential nutrient for yeast growth) that is (11.9), and initial concentration of yeasts (2.5 g/L). Three kinematic models (Monod, Verhulst, and Tessier) were also selected for the purpose of studying the kinetic performance of S. cerevisiae yeast, and the best results were obtained based on the Verhulst model. The Leudeking Piret model has also been successfully used to estimate substrate during fermentation.
Using Multi-Objective Land Allocation Model to Simulate Urban Growth: The Case of Sarakhs Border City in Iran
Authors: Rahim Rahnama Mohammad 
Published: March 2023

This chapter’s purpose is to simulate urban growth of Sarakhs, using a Multi-Objective Land Allocation (MOLA) model. To achieve this goal, Landsat 7 and 8 and Sentinel 2A satellite images from 2003 to 2020, and 13 variables affecting the location of land uses with spatial decision model (SDM), multi-criteria evaluation (MCE), and MOLA model were used. Considering the increase in the city’s population from 2020 to 2030 and the possibility of turning the city into a Free Economic Industrial Zone (FEIZ), about 322 hectares of land for residential use and 500 hectares for industrial use were estimated until 2030. By using MOLA model, the location of residential and industrial land use with a distance from agricultural lands was simulated in the west of the city. The result of the residential land use simulation is in line with the projected development direction of the City Master Plan to a large extent. But industrial land use is predicted in the vicinity of the Special Economic Zone (SEZ) in the west of the city. Therefore, the research results can be used in simulating of urban growth due to high speed, accuracy, and low-cost compared to traditional methods of preparing Master Plans in the Third World cities.

Published: March 2023

Effect of treatment of coupling agent (mono-alkoxy pyrophophato
coupling agent) on mechanical properties of composites made from
HDPE/EVA/Mg(OH)2/ Composites is reported here. The coupling
agent in the form of solution (1.5%) was used for treatment of the
filler .The treatment resulted in enhancement of mechanical properties
of composites when compared with composites containing untreated
Magnesium hydroxide. The properties under consideration were
tensile strength, modulus at (%) elongation at break, elastic modulus,
hardness, etc. Although good reinforcement was observed due to
treatment of 1.5% coupling agent, observed was very much
remarkable by its comparing to untreated once. Comparison of
properties of composites filled with treated and untreated Magnesium
hydroxide established that the treatment of Magnesium hydroxide
imparts better reinforcing properties. The properties under
consideration were tensile strength, (%) elongation at break, elastic
modulus, hardness, etc. Tensile strength was improved by 19.10%,
(%) elongation at break was improved by 9.01%, elastic modulus was
improved by 100%, while hardness was improved by 0.5%, at (0.14)
volume fraction.

Authors: Al-Hawbani Ali M. 
Published: March 2023

The Suwar Ni-Cu sulfide host rocks are located at the northwest of Yemen, about 18 km of Hajjah city. The host rocks at Suwar are associated with the ultramafic component of differentiated gabbroid intrusive.
The results of chemical analysis of the major elements present in host rocks of Ni-Cu in Suwar area shows that, the magnesium oxide ranges from 20 to 30% , the silica oxide has an average 40% and iron oxids is also variegate between 14.4 and 18%.
Based on the comparison between the results of the studied Ni-Cu sulfides in Suwar area with that obtained from famous international host rock, it is clear that there is a possible large collection of sulfides and Suwar host rocks which belong to the group which contains magnesium oxide (MgO) ranged between 15 and 33%, associated with high percentage of nickel and low percentage of copper. It also indicates similarity to Jinchuan and Kambalda magmatic bodies in China and Australia respectively. In addition, it shows that the nickel increases in ore with the increase of MgO contents in hosted rocks. Thus, there is a possibility of increasing percentage of nickel concentration in Suwar ore while the study is in progress.
Effects of Some Gate Lip Shapes on Downpull Force in Dam Tunnels
Authors: Ahmed Thamir M. 
Published: March 2023

The gate which controls the flow through the dam tunnel is termed as lift gate. Such gates are subjected to the hydrostatic and hydrodynamics forces, since the flow passes over and beneath the gate and produces pressures at the top and bottom of the gate surfaces. The differences between these two pressure forces are termed as downpull force. The evaluation of this force is very important due to its effects on closure of the gate, its positive and / or negative values.
The estimation of downpull force requires the determination of top and bottom pressure coefficients for wide range of discharges, gate openings, velocity, and pressure distribution in many locations .For the present research these measurements have prepared for different types of gate lip shapes along with laboratory hydraulic tunnel model which have been used. Various flow conditions and gate openings have been examined .The results concluded from the measurements and analysis tend to confirm the effects of the gate lip shapes on the values of downpull force, which in case of its negative value will prevent the gate to close and make some failures and damages.
Missed Miscarriage Runs without Complete Evaluation: A Retrospective Study
Authors: Al Harazi Abdelrahman H 
Published: March 2023

The causes of missed miscarriage are often unknown. The aim of this study was to know the rate of missed miscarriage and to assess whether the underlying causes are identified at time of termination. This study was a retrospective carried out in Al-Saba’een Hospital – Sana’a during a year (from Jan. 1st to Dec. 31st 2010).
The hospital records were reviewed for all women admitted with miscarriage. The women with missed miscarriage were identified and their demographic and clinical data were obtained. The histopathological results noted when available. Of the 621 miscarried women, 225 patients were diagnosed as having missed miscarriage giving the rate of 36.2% of the overall miscarriages. Only 17.3% of these cases the underlying etiologies were diagnosed whereas in the remaining 82.7% patients the causes of loss were undetermined (p=0.0002). The histopathological study was performed only in 18.7% of patients.We concluded that missed miscarriage more frequently runs without complete evaluation of the underlying causes. It is a neglected and invisible issue and more efforts are needed to translate the theoretical knowledge into proven practice.

Authors: Al-Alousi Maha , Al-Makdad Abdulsalam , Al-Jarfi Arafat 
Published: March 2023

Viral hepatitis is a general term meaning inflammation of the liver and can be caused by a variety of viruses such as hepatitis B virus.
Hepatitis B is a serious transfusion-transmissible disease affecting millions of people throughout the world.
This study was designed to evaluate the prevalence of HBsAg and the risk factors for HBV infection among blood donors in Thamar governorate/Yemen, and to focus upon the importance of blood transfusion in spreading the hepatitis B virus.
A total of 200 blood donors at the blood bank of Thamar hospital and Al-Wehda teaching hospital, during the period of January 2009 to October 2009, and January 2010 to July 2010, were screened for the presence of hepatitis B surface antigen (HBsAg) . Each patient filled a questionnaire including age, sex, dental visit, blood transfusion ..etc. The donors were all male adult (age: 17-45 years).
Four out of 200 (2%) donors were found to be HBsAg positive by an enzyme-linked immunosorbent assay (ELISA) using monoclonal antibodies to HBsAg. Two of the four (50%) HBsAg-positive donors have relative symptoms of HBV (i.e jaundice) while the other two HBsAg-positive donors were asymptomatic. Questionnaires revealed that: The four positive donors were all married. The two asymptomatic HBsAg-positive donors were army soldiers. The other two symptomatic donors were civil workers.
One of the two asymptomatic donors has donated a blood a year ago and found to be HBsAg negative.
One of the symptomatic positive donors has had two previous surgical operations and received several pints of blood.
This study emphasizes the need for an accurate detection of this virus, and the need for using confirmatory tests for HBsAg detection and also the need to undertake serious measures to control the spread of HBV among Yemeni people.

Factors influencing school nurse service utilization in selected schools of Kathmandu district: a mixed method study
Authors: Sharma Saraswati , Bhandary Shital 
Published: March 2023

Introduction: One school one nurse is a new program in Nepal aiming to improve students' health. This study aimed to find utilization of school nurse service and associated factors in selected schools of Kathmandu district using mixed methods approach.

Method: Study included Kirtipur Secondary School and Shivapuri Higher Secondary School. It used concurrent triangulation mixed method design. Quantitative phase included survey among 30 students, 15 from each school while qualitative phase had 4 in-depth interviews and 2 key informant interviews. Fisher’s exact test and Braun and Clarke’s six-step thematic analysis based on socio-ecological model were used to analyze factors associated with service utilization quantitatively and qualitatively. Results were triangulated using convergent, divergent and expansive findings.

Result: Out of 30 participants, 27(90%) had ever contacted to school nurse for any health issue. Student's visit to school nurse for mental health issue was the only factor found significantly associated with frequency of visit. Qualitative analysis explored many associated factors at different socio-ecological level. No sex wise variation in sharing sensitive health issue with school nurse was convergent finding. Divergent findings were identified regarding factors like health issues to visit school nurse, motivator, perceived privacy and sex. Expansive finding was that a school nurse appointed in a school also served nearby schools beyond her job description.

Conclusion: An effort from individual level to policy level is needed to resolve hindering factors of school nurse service utilization and maintain the promoting ones.
