In the solution of soft soil improvement by preloading method combined with prefabricated, the horizontal consolidation coefficient Ch is a very important parameter to help predict the settlement speed of soft soil. But when designing the coefficient of horizontal consolidation, it is often assumed that the coefficient of vertical consolidation is quite large. This can lead to settlement over time that will fluctuate in a rather large range of values. In this paper, research and evaluation of the horizontal consolidation coefficient Ch by dissipation test on piezocone penetration device with pore water pressure measurement has been mentioned to determine the permeability parameters in-situ for the soft soil improvement at the projects.

In the world, cyclic triaxial tests are widely used to evaluate the liquefaction potential of soil and determine the cyclic parameters for seismic design. However, the application of cyclic trixial test for evaluation of soil liquefaction is still limited in Vietnam. This paper introduced the cyclic triaxial apparatus, method and testing procedure to access the liquefaction potential of sand under cyclic loading. The research on some saturated sandy soils with high fine-grained content in Vietnam showed that the research results of soil liquefaction potential is reliable. In which, the liquefaction characteristics of sand are evaluated based on the changes of stress, strain and pore water pressure according to the cyclic cycles, thereby determining the liquefaction point and liquefaction boundary for fine sandy soils at different density levels.

Published: November 2023

Laboratory tests are essential for analyzing the behavior of geotechnical materials and models. Two of the most common methods for measuring displacement in laboratory tests are Dial indicator and Linear variable differential transformer (LVDT). However, using these equipments has some limitations, such as measuring only discrete points, and Dial indicators require surfaces to be measured must have a certain hardness. This feature is a significant limitation because geomaterials are not usually rigid masses. To overcome these limitations, the authors studied using laser cameras to support the LVDTs and the Dial indicators. Laser cameras offer high sampling rates, but their accuracy needs to be carefully investigated as they are mainly used to measure large distances. In this paper, we show how to investigate the accuracy of laser cameras with reliable, intuitive observations, reviewing recent studies on using laser cameras in laboratory tests. Experiments, including their advantages, limitations and potential applications: The potential application of laser cameras to measure distances can be evaluated instead of LVDT. We also discuss the challenges and future directions of using laser cameras in laboratory testing. The results showed that laser cameras could improve the accuracy and efficiency of laboratory tests and may become a preferred method for displacement measurement in the future.

In determining pile bearing capacity, static load testing is still considered a highly reliable method and can be used to verify pile load calculations by other methods (BS EN 1997-1:2004, 7.4.(1)P). In practice, often difficult to define an ultimate limit state from a load settlement plot showing a continuous curvature (BS EN 1997-1:2004, 7.6.1.1(3)). Therefore, the determination of pile load capacity from static compression test results is currently not consistent among standard systems. Besides, each standard stipulates different pile static compression test procedures leading to different methods of determining pile load capacity. The article practices calculation of pile load capacity from static compression test results by different methods, thereby comparing the results and making comments.

With the current construction requirements of high-rise buildings, the demand for tower cranes is increasing. It is a construction support device, which helps to transport materials in large quantities quickly and save time. Currently, in the country, the documents on the design, manufacture and safe operation of tower cranes are quite complete. However, there are no guidelines/standards on specialized construction design for tower crane foundations. The majority of construction engineers do not determine the complete and correct tower crane foundation calculation procedure. The selection of references for calculation is also not simple. Therefore engineers often rely on experience, not much in fact, to design. This leads to difficulties in design practice and costs. From the above actual needs, a draft of the tower crane foundation calculation has been compiled. Here are some issues to keep in mind when designing tower crane foundations.

Published: November 2023

The objective of economic stability is fundamental to relative wellbeing of any country. Therefore, exchange rate management is key to fueling growth potentials and relative macroeconomic stability. The study empirically examined the exchange rate management and selected macroeconomic nexus in Nigeria from 1981Q1 to 2021Q4. The technique of generalized auto regressive conditional heteroscedasticity GARCH (1,1) was employed to model the dependent variable of quarterly nominal effective exchange rate( QNEER) on the explanatory variables : quarterly external reserves(QEXRES);quarterly gross domestic product (QGDP) ,and Dummy of effective exchange rate policy (DUMEXPO). The research output showed exchange rate depreciation in Nigeria exhibited a statistically significant inverse relationship with external reserves and gross domestic product during the review period. Whereas, test of exchange rate management policy effectiveness showed a relatively weak policy thrust are implemented to stabilized exchange disequilibrium. The study however, recommended for a consistently well recalibration of exchange policy as well as monetary policy intervention strategies so as to restore convergence, attract capital inflow and macroeconomic equilibrium position.

Published: November 2023

The negative impact of oil and oil products on the environment is well known and represents the most important ecological problem. Although manufacturers and logistics services work in compliance with environmental legislation, oil, and its products still occur in the environment. As a result, oil transformation products enter the biosphere, and change the composition of soils, surface and underground waters, and the atmosphere. The research aimed to study the content of petroleum products in the waters of the Bartskhanistskali River and evaluate its ecological condition. The river Bartskhaniststskali flows into the territory of the city of Batumi and is attached to the Black Sea. Most of the entire catchment area of the river is crossed by roads close to the Batumi oil terminal and the main oil highway. It studied the quantitative and qualitative conditions of the Bartskhanistskali River in two observation areas: one at the mouth of the sea, and the other 5 km from the head of the river. The experiment was conducted in 2022–2023, and water samples were taken in different seasons. The results of the study showed the change in the oil content in the Bartskhanitskali River in different research areas and in different seasons of the year. The concentration of the pollutant in the water is variable and dependent on climatic conditions (temperature) and weather. The highest level of oil content was recorded in the river area, where highways, oil reservoirs, and transfer pipes are adjacent. Its content is also especially high in summer.
Effects of Silvicultural Interventions on Carbon in High Mountain Forests in Türkiye
Authors: Oktan Ercan , Kalender Aysen
Published: November 2023

High montane forests are defined as forests between high montane (oreal) and subalpine ranges, which are under pressure against extreme climatic conditions and anthropogenic influences and have difficulty in regenerating themselves under these conditions. High montane forests, which are constantly struggling with poor growing environment conditions, have difficulty in regenerating themselves and cannot respond to the forestry activities implemented. However, due to unfavorable terrain and climatic conditions, carbon accumulation in both subsoil and above-ground vegetation in high mountainous areas remains in very low amounts. Therefore, silvicultural interventions that can be applied by increasing the carbon stock capacity of high mountain forests and revitalizing the ecological role of high mountain forests should be done in accordance with their nature. In order to increase the amount or potential of carbon storage, conservation and sustainable use of forest ecosystems are important for combating climate change and global carbon balance. Therefore, special planting practices should be implemented in high mountain forest areas to accelerate carbon storage. As a result, the potential production, biomass increase and carbon sequestration capacity of high mountain forest areas can be better utilized. Within the scope of this study, the effects of silvicultural interventions on carbon in high mountain forests in Türkiye will be evaluated.

Published: November 2023

Many expectations such as benefiting from forests all year round, providing transportation for people, protecting forests, transporting wood raw materials are only possible with forest roads that provide access to forests. Today, with the increase of global warming, forest fires have affected the whole world. If the forests cannot be reached and intervened during the fire, the forests that hold carbon start to release carbon during the fire. This situation reveals the importance of forest roads, which make it possible to fight fires. In this study, the effect of forest road construction on existing forest asset will be tried to be revealed by using geographic information systems. For this purpose, analyzes were carried out on a forest road built in 2019 in Osmangolu Forest Management Directorate, which is within the borders of Kastamonu Regional Directorate of Forestry Ilgaz Operation Directorate. Controlled classification was made using SNAP software on two satellite images of 2018 and 2023 and the current forest change was revealed. By determining the differences between these two situations, the effect of this change on forest carbon, the effects of the road construction area on the surrounding stands and the condition of these stands after the road construction were evaluated. As a result, the relationship between the construction of a forest road and the existing vegetation and thus forest carbon has been tried to be revealed.

Published: November 2023

Forests are one of the important carbon sinks that struggle with the possible negative effects of global climate change. In this sense, it is very important to determine the carbon calculations in forests with the right methods in order to take measures against climate change. In many studies, it has been determined that the carbon stored in forest ecosystems varies according to the forest structure. Therefore, it is important to determine separately the effects of stand establishment, tree species, bedrock and soil characteristics on carbon storage. Features such as age, stratification, closure, density and mixing ratio that make up the stand establishment are effective on the amount of carbon stored and to be stored. For this purpose, carbon storage amounts of Alder (Alnus glutinosa L.) in different stand establishments were calculated in this study. This study was carried out on the Alder stands affiliated to Trabzon Forest Management Directorate, Düzköy Operation Chief. Since 2008, biomass and carbon calculations of our forest areas have been made with the method mentioned in the Ecosystem Based Functional Forest Management Plans (ETFOP). In this study, BEF coefficients developed based on FRA-2010 within the scope of ETFOP were used. In the study conducted with samples taken from three different sections in the stand, the amount of above-ground carbon storage (TUK) was found to be 1.7233 tons in section 1 with 0.4-0.5 confinement. The amount of TÜK was found to be 2.8208 tons in the 2nd compartment with 0.3-0.4 closure. The amount of TÜK was found to be 2,0557 tons in the 3rd compartment with a clearance of 0.2-0.3. In this context, carbon storage amounts for each stand differed depending on the changes in the factors that make up the stand establishment.

Forest ecosystems, which have an important role in the global carbon cycle by storing large amounts of carbon in the above-ground, below-ground and soil, make up about 30 % of all terrestrial ecosystems. Two different methods are used to determine the amount of carbon stored in forests. In both methods, different parameters should be determined by stand measurements. However, new methods are needed because it is time -consuming and costly to do these studies. In this context, the determination of the carbon storage capacity of forest areas by using the data obtained by remote sensing methods has come to the agenda. For this purpose, the stands selected as a study area were determined with the help of measurement data of terrestrial carbon storage levels in the Gazipaşa Central State Forest Enterprise of Antalya Regional Directorate of Forestry in Mediterranean region. In the satellite image (Sentinel), the relationship obtained from the brightness values of various bands and the amount of carbon stored to be determined by various vegetation indices have been established.

The negative effects of global warming, which is the most important environmental problem particularly during last two decades, continue to negatively affect all social life and the future of the world's natural resources. Increasing the carbon storage level is very important in mitigating the effects of this global problem. In this regard, it is necessary to protect the existence of natural resources with high carbon storage capabilities as well as creating awareness of social environmental cleaning. Forests are at the forefront of these important natural resources. Forests, which naturally have the ability to renew themselves, have different carbon storage abilities at every age and growth stage. However, the problem of global warming, the effectiveness of which is increasing rapidly, negatively affects this important feature of forest resources in terms of carbon storage. In this research, the possible changes in the carbon storage capacities of the forests in Dirgine province, which is located in the Western Black Sea Region, which is one of the regions with productive high forest resources which has very valuable pure and mixed forest resources, due to the effects of global warming, were investigated by using climate change models. For this purpose, Shared Socio-economic Pathways (SSPs) presented in the 2021 IPCC sixth evaluation report (AR6) for the years 2040, 2060, 2080, and 2100 in the WorldClim database, using 19 different bioclimatic variables, including altitude, and aspect, according to 245 and 585 global climate change scenarios. Modeling was done with Maximum Entropy software using topographic variable. As a result of the model applications, the annual mean temperature, the maximum temperature in the warmest months, the mean temperature in the driest period, the mean temperature in the warmest period and seasonal precipitation were determined as the bioclimatic variables that have the most important effects on the change in the carbon storage capacity of pure and mixed stands in the research area. According to these model applications, the carbon storage capacity of pure forest will decrease by 13.6% in 2040, 23.8% in 2060, 34.7% in 2080 and 41.3% in 2100. Depending on the effects of global warming, it has been determined that it will weaken by 11.5% in 2040, 20.7% in 2060, 30.8% in 2080 and 37.9% in 2100 in the mixed forest resources in the Dirgine province.

Published: November 2023

“Kesong puti,” a local variety of soft cheese, is known in some parts of the Philippines but it is less acceptable in the Visayan region. The incorporation of sweetened purple yam is seen to improve the cheese’s flavor and overall appeal. The addition of probiotic starter curter was intended to produce a probiotic flavored cheese with viable number of live microorganisms. This study was conducted to evaluate the growth of live lactic acid bacteria (LAB) on the flavored cheese. It also determined the formulation and processing condition that produced sufficient level of live microorganisms on the probiotic product to deliver its intended effects. Results of the study revealed the microbial count to be generally high, exceeding 106 cfu/g, in the treatments incubated at 44°C for 15 hours and treatments with low concentrations of salt. The incubation period showed a direct relationship with the microbial count. Growth of LAB increased with the corresponding increase of the incubation period. Salt, however, offered an inverse relationship with the microbial count. At constant incubation time, treatment with 1.0% salt concentration produced higher bacterial growth than treatments with 2.5% and 4.0% salt.

The eggplant fruit and shoot borer (Leucinodes orbonalis Guen´ee), also known as EFSB, is anotorious major insect pest of eggplants. Researchers have been striving to find effective management strategies to reduce the population of this pest and achieve higher yields with minimal or no insecticide application. This study aimed to investigate the influence of intercropping eggplants with different repellent plants as a means to mitigate EFSB infestation, considering the heavy reliance on insecticides in eggplant production. The experiment followed a Complete Randomized Design (CRD) with six treatments replicated three times.The treatments included lemongrass, oregano, marigold, a combination of repellent plants (lemongrass + oregano + marigold), farmers’ practice (methomyl), and the control (sole eggplant). Data analysis was conducted using analysis of variance, and the differences across treatment means were calculated using Tukey’s Honest Significant Difference. The results revealed that intercropping eggplants with marigold, oregano, and lemongrass exhibited repellent effects on EFSB moths, leading to a significant reduction in the percentage of shoot damage. These findings suggest the potential utilization of intercropping with repellent plants as a more environmentally friendly approach, reducing the need for insecticide usage and potentially increasing farmers’ income.
Conspecific Homogenate Pyloric Caecum, Feeding Attractant for the Crown-of-Thorns Starfish Acanthaster planci

Published: November 2023

The responses of crown-of-thorns starfish (COTS) Acanthaster planci to water-borne stimuli derived from conspecific homogenate of COTS pyloric caeca, tube feet and test and injured conspecific, was investigated to establish its potential application as COTS attractant or repellent. The study followed a randomized complete block design (RCBD) with blocks corresponding to 50 replicates per treatment with one (1) individual starfish per treatment level. Each of the six COTS was placed at the center of the choice chamber with a distance of 1.25 m at both ends. Closed-circuit television (CCTV) was installed to provide additional monitoring. Ninety (90%) to ninety-eight percent (98%) of the 50 samples responded to the conspecific stimuli. COTS displayed significant response towards the homogenate pyloric caeca (X2=3.9; df=1; p<0.05) and away from injured starfish (X2=4.18; df=1; p<0.05). The chemo attraction and avoidance of COTS to the crude extract of pyloric caeca and injured COTS could be due to the product of digestion from coral tissues and the release of saponin to alert others by predation. The capability of COTS to detect water-borne stimulus derived from the conspecific homogenate of pyloric caeca and injured starfish provided us the knowledge to develop COTS feeding attractant and repellent system.

Yoghurt is a probiotic product due to the presence of beneficial microorganisms so-called lactic acid bacteria (LAB). However, the viability of LAB in the product must reach the optimum microflora balance of 106 to 108 cfu.ml-1 to be considered as probiotic and for consumers to enjoy its health benefits. One of the alternatives in maintaining the viability of LAB in yoghurt is to encapsulate the LAB cells which would protect the cells from the environment. In this study, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, the yoghurt starter cultures, were encapsulated in different levels of alginate-taro starch matrix. Physico-chemical properties of the reconstituted skim milk medium and the sensory qualities of resulting yoghurt were determined. The developed alginate-taro starch encapsulated, non-encapsulated and pure alginate encapsulated starter cultures were compared in terms of their effectivity in yoghurt production. The highest percentage of taro starch (1.5%) was found to retain a high viable cell count of 3.4 x1010 cfu.ml-1 after 12-day storage at 4oC. No significant effect of encapsulated starter cultures was observed on the physico-chemical properties (i.e. pH, TSS, and % lactic acid) of reconstituted skim milk. Incubation and storage periods significantly affected the physico-chemical properties of the reconstituted skim milk (p <0.05). No significant differences among the treatments were found for sensory qualities. However, the yoghurt produced from 4% alginate-1.5% taro starch-encapsulated LAB, which was stored for 2 weeks, was found to be acceptable due to its right degree of sweetness and acidity and similarity with the control treatment. It can be concluded that taro starch is, indeed, a potential wall material that can be used with alginate to encapsulate yoghurt starter cultures and can retain or increase the lactic acid bacteria cell viability without affecting the activity of the cultures.

Based on the content of the previous two projects, the objective of this project is to collect quantitative data through a survey questionnaire and qualitative data through in-depth interviews. The author uses both methods simultaneously to collect data in both breadth and depth, to gain an overall understand of the topic. After collecting quantitative and qualitative data from 301 valid survey questionnaires, the author uses statistical software such as SPSS and AMOS to analyze the data. Both qualitative and quantitative analyses produced consistent results. Specifically, (1) Factors such as welfare policies, training activities, recruitment and selection, information sharing, job challenges, delegation of authority in the enterprise, and safe working environment have a positive impact on employee commitment to the organization; (2) Employee commitment has a positive impact on the quality of human resources; (3) The quality of human resources has a positive impact on the development of human resources. The findings of this topic provide us with an objective and overall view of the field of human resource development in organizations. From this, we can develop practical policies to apply in management practices to continuously improve the quality and performance of human resources.

Published: November 2023

Organizational Citizenship Behavior (OCB) is a challenge in the world of work today, because organizations will certainly feel happy if they have employees who behave OCB. Organizations need to pay attention to employees and be able to manage employees so that they have superior employees that are not owned by other organizations. In this case it will also be beneficial for the organization. Problems that occur in organizations related to work ethics such as discipline. Therefore, it is necessary to build an OCB model that impacts Job Satisfaction in the workplace. In order to solve these organizational problems, it can facilitate the emergence of a work ethic. This research is a quantitative study, with a sample of 138 respondents from PT Pertamina Lubricants â€“ Production Unit Cilacap. Multiple linear regression analysis instruments and data processed using SPSS. The empirical test results prove that the dimensions of OCB including altruism, awareness, politeness, sportsmanship, and the virtues of citizenship have a significant effect on job satisfaction. The contribution of this study uses the perspective of human capital theory with managerial implicit which emphasizes the importance of building an adaptive work environment, building a better colletivism culture and increasing spirituality in the workplace.
