An Attempt to Delineate Subsurface Ain Aldawar Cavity Using 2D Electrical Resistivity Imaging Method in Haditha Area, Western Iraq
Authors: Abbas Samir , Al-Saady Hussein , Al-Mahemmdi Waleed
Published: June 2024

The current study used 2D resistivity imaging to identify a shallow subsurface cavity in Haditha, western Iraq. The cavities and voids near the surface restrict land use and create a variety of geotechnical hazards, such as land subsidence, infrastructure damage, and structural cracks. As a result, the presence of an underground weak zone is a major concern for engineers before beginning any development, given the risk of future disasters. The four 2D resistivity traverses in this study were carried out using a dipole-dipole array with a - spacing of 3 m and an n-factor of 6. The data was inverted using RES2DINV software, which employs robust inversion methods. The 2D inverse model reveals a shallow cavity ranging from 5 to 12 meters and a width of around 40 m.
New Research Results on U-Pb Zircon Isotope Age of Ta Cu Granodiorite in Dalat Zone and Geological Significance
Authors: phuc le , Minh Pham , Hieu Pham , Vi Trinh
Published: June 2024

Ta Cu granodiorites from the Dalat Zone, Southern Vietnam, have typical composition of granodiorite, coinciding with the Dinh Quan complex. The granodiorites are composed of plagioclase (45–50%), quartz (20–25%), orthoclase (15–20%), hornblende (5–7%), and biotite (5–7%). Geochemically, they are met aluminous with an average A/CNK value of 0.89- 0.96, low SiO2 (61.68-62.14) and high Na2O/K2O> 1. Petrographical and geochemical characteristics of Ta Cu granodiorites are classified as I-type granite generated from arc-related magmas. Zircons selected from these rocks are characterized by prismatic shape, oscillatory zoning, no luminescent rim, and have high ratio Th/U (0.35–1.11) that are indications of the magmatic origin. We report the first LA-ICP-MS 206Pb/238U zircon ages of 116 Ma for the Ta Cu granodiorite in the Southeastern Dalat Zone in Southern Vietnam. This age value is temporally coeval with Early Cretaceous magmatism previously reported in the Dalat Zone. Zircon ꜪHf(t) values +4.0 to+13.0, whole-rock ꜪNd(t) values -2.0 to +0.2, and average model ages (TDM2) 652 Ma to 957 Ma indicate that the Ta Cu granodiorites were derived from the remelting of Neoproterozoic mantle-derived melt with a minor input of crustal materials. Together with other Late Mesozoic magmatic complexes along the Dalat Zone, the Ta Cu granodiorites are a representative of magmatism linked to Pacific Ocean subduction beneath the Indochina block during the Early Cretaceous.

Published: June 2024

This research investigates the heavy metal pollution in karst lakes, crucial for fisheries, agriculture, and domestic activities. Target metals include Pb, Cd, Cr, Fe, Zn, and Cu. Objectives comprise assessing pollution levels via the Heavy Metal Pollution Index (HPI) and conducting an ecological risk assessment, incorporating the Enrichment Factor, Geoaccumulation Index, and Ecological Risk Index. The Pearson’s correlation and cluster analysis were performed to analyze the connection between samples. Results reveal strong correlations between metals in soil and sediment, such as Pb in soil correlating with Cu in sediment (r = 0.88), Zn in soil with Cu in sediment (r = 0.75), and Zn in soil with Pb in sediment (r = 0.81). Kedokan Lake emerges as the most representative observation (distance 13.1), while Kepleng Lake is the least representative (distance 535). Cluster analysis identifies two distinct clusters: Cluster 1 encompasses Ngrejek Lake, Kedokan Lake, Sodong Lake, Kanigoro Lake, and Ngampelombo Lake. HPI calculations reveal varying contamination levels in lake water and underground river samples within the Bribin Underground River Catchment Area. Notably, one location in Kedokan Lake is categorized as contaminated (HPI value of 188.05). Mean Enrichment Factor values range from no enrichment factor (<1) to low enrichment factor (1–3). Geoaccumulation Index (Igeo) indicates an overall unpolluted classification (Igeo<0) across all sampling sites. These findings underscore the nuanced pollution status in the studied area, emphasizing the importance of continued monitoring and intervention to ensure the sustainability of karst lakes in the face of heavy metal contamination.

Authors: Al-Owaidi Mohanad , Hussein Mohammed , Al-Rubaiee Abdul-Kareem
Published: June 2024

The limestone of the Nfayil Formation was studied in Diwaniya Governorate, west Euphrates River, southern Iraq. The analyses of the Geochemical and Geotechnical properties showed that the Nfayil Formation limestone is suitable for the Portland cement industry. The results indicated that the averages are 91% lime, 4.9% magnesia, and 0.4% alkalis. While, the average uniaxial compressive strength is 95 mega N/m², reflecting high toughness on average. These oxide percentages are expected to theoretically achieve the mineral phases of the produced clinker when using Bogue equations, which are compatible with international standards. This studied site contributes extra quantities to the reserves of limestone raw materials suitable for the cement industry. It opens prospects for establishing a new cement factory close to cities in central Iraq.
PHARMACEUTICALLY ACTIVE COMPOUNDS (PhACs) IN WATER OF ASIAN COUNTRIES: A META ANALYSIS REVIEW ON THE OCCURRENCE, DISTRIBUTION AND ENVIRONMENTAL RISK
Authors: KAMARUDIN SITI NUR ZAHIRAH , TUAN OMAR TUAN FAUZAN
Published: June 2024

Pharmaceutically active compounds (PhACs) have received a lot of attention due to their enormous consumption proportions, significant bioactivity, and prospective ecotoxicity that tend to impact the health of marine ecosystems and humans. In this study, five commonly used pharmaceuticals were studied in water bodies of Asian countries. The main objective of this study was to review the occurrence and distribution of selected PhACs such as diclofenac, fluoxetine, caffeine, propranolol, and triclosan in the water bodies of Asian countries. This review was found that the range of concentration of pharmaceuticals was 0.055 to 11.4 x103 ng/L. Five distribution maps were plotted using the Geographical Information System (GIS) software. China has been identified as the country that discovered most of the selected PhACs occurrence and distribution compared to other nations. Data obtained from the present review was analyzed for risk assessment analysis using the Risk Quotient (RQ) technique, which is typically applied to assess PhACs with potential ecological concerns in water ecosystems. The findings of the study showed that 31 RQ was found to be non-significant. Fluoxetine compound was classified as having the highest RQ value calculated for phytoplankton, with an RQ value of 136.08. Hence, PhACs surveillance in the water ecosystems must be strengthened, and research on PhACs occurrence and potential risks should be highlighted in global environmental research.

Published: June 2024

The goal of this study is to ascertain whether the essential oils (EOs) derived from the plants Pandanus amaryllifolius (pandan) and Cymbopogon citratus (lemongrass) have any potential to be effective insecticides against the adult Rynchophorus ferrugineus (red palm weevil, RPW). The effectiveness of the EOs is evaluated based on their capacity to kill RPW instantly upon contact and also on their ability to block acetylcholinesterase (AChE) enzymes. These EOs’ impact on protein synthesis was also identified. After five days of exposure, the mortality rate of RPWs was found to be between 11% and 33%, with female RPWs being more affected than male RPWs. However, increasing the concentration of EOs from 5% to 10% (v/v) had no discernible effect on mortality. Both EOs are ineffective AChE inhibitors because they had no effect and rather increased the activity of the enzyme. The enzyme AChE in female RPWs is significantly inhibited by just 10% of the lemongrass. With the exception of 10% EOs, which markedly increased the TSP of female RPWs, the RPWs’ total soluble proteins (TSP) were much lower after treatment. In conclusion, both EOs have the potential to be applied as insecticides against adult RPW. Additionally, it may be said that both EOs function in a similar way towards RPW. These results add to the body of knowledge regarding the search for new insecticides that may be helpful in controlling the RPW because this study has yet to be conducted before.

Leptospirosis is a zoonotic disease caused by Leptospira, which is transmitted through infected mammalian species, including small mammals. However, the prevalence of pathogenic Leptospira spp. in small mammals, particularly between different site categories in the eastern part of Peninsular Malaysia, is still underexplored. Therefore, in this study, we aimed to determine the species composition of small mammals and the prevalence of pathogenic Leptospira spp. between different site categories from Dungun, Terengganu. We selected five case sites (leptospirosis cases were recorded) and five control sites (no leptospirosis cases were recorded) in Dungun, Terengganu, based on previous reports by the Ministry of Health (MOH) Malaysia (2016-2020). For three consecutive nights, 100 cage traps were used for each trapping session. In addition, kidney samples from captured individuals were extracted for the Polymerase Chain Reaction (PCR) detection of pathogenic Leptospira spp. Overall, 89 individuals from five species were captured (6.43% trapping success), consisting of Rattus norvegicus (n = 39), Rattus rattus (n = 27), Suncus murinus (n = 11), Rattus exulans (n = 10) and Tupaia glis (n = 2). Out of 89 individuals captured, 14 tested positive with a 15.7% (n = 14/89) prevalence rate. R. norvegicus was the most dominant captured species and had the highest number of infected individuals with pathogenic Leptospira (20.5%, n = 8/39). The statistical analysis revealed that there is a significant difference in pathogenic Leptospira spp. between case and control sites (P < 0.05), with control sites recording higher positive individuals (78.6%, n = 11/14) compared to case sites (21.4%, n = 3/14). However, no significant differences were observed between species and sex (P > 0.05). The results show that the monitoring of leptospirosis cases should not only focus on case areas but also control areas in order to prevent the outbreak of this disease in the future.

Studi global menunjukkan bahwa penyandang disabilitas menghadapi tantangan besar dalam menghadapi bencana, terutama selama pandemi COVID-19. Tulisan ini mengevaluasi respons kebijakan pemerintah terhadap kebutuhan kelompok ini dalam penanggulangan bencana di Indonesia. Fokusnya adalah empat kebijakan nasional terkait: Undang-Undang No. 24 Tahun 2007 tentang Penanggulangan Bencana, Undang-Undang No. 8 Tahun 2016 tentang Penyandang Disabilitas, Peraturan Pemerintah No. 42 Tahun 2020 tentang Aksesibilitas pada Permukiman, Pelayanan Publik, dan Pelindungan dari Bencana bagi Penyandang Disabilitas, serta Peraturan Kepala BNPB No. 14 Tahun 2014 tentang Penanganan, Perlindungan, dan Partisipasi Penyandang Disabilitas dalam Penanggulangan Bencana. Melalui perspektif inklusivitas, analisis ini menyoroti sejauh mana kebijakan mendukung upaya perlindungan, pemenuhan hak, dan partisipasi penyandang disabilitas. Pengumpulan data dilakukan melalui analisis substansi dan implementasi kebijakan, serta diskusi kelompok terpumpun dan wawancara semi- terstruktur dengan para pemangku kepentingan. Hasilnya menunjukkan bahwa regulasi saat ini belum optimal dalam mengakomodasi unsur inklusivitas yang diperlukan, sehingga memengaruhi implementasinya. Rekomendasi utama mencakup tinjauan ulang kebijakan, penyelarasan kebijakan terkait, dan alokasi anggaran yang komprehensif untuk mendukung penanggulangan bencana inklusif, khususnya bagi penyandang disabilitas.Abstract Global studies indicate that individuals with disabilities face significant challenges during disasters, particularly amid the COVID-19 pandemic. This paper evaluates the government’s policy response to the needs of this group in disaster management in Indonesia. It focuses on four relevant national policies: Law No. 24 of 2007 on Disaster Management, Law No. 8 of 2016 on Persons with Disabilities, Government Regulation No. 42 of 2020 on Accessibility for Settlements, Public Services, and Disaster Protection for Persons with Disabilities, and Head of the National Disaster Management Agency Regulation No. 14 of 2014 on the Treatment, Protection, and Participation of Persons with Disabilities in Disaster Management. Through an inclusive perspective, this analysis highlights how these policies support inclusive efforts for the protection, fulfillment of rights, and participation of individuals with disabilities. Data collection involves substantive and implementation policy analysis, focus group discussions, and semi-structured stakeholder interviews. The results indicate that the current regulations are not optimal in accommodating the necessary inclusivity elements, affecting their implementation. The main recommendations include a policy review, alignment of related policies, and comprehensive budget allocation to support inclusive disaster management, especially for individuals with disabilities.
Dampak Konseling Kelompok dalam Pencegahan Relaps Narapidana Narkotika Keluar Lapas Salatiga dan Ambarawa
Authors: Purwandari Eny , Kanafi Mochamat
Published: June 2024

Drug abuse remains a national issue that is difficult to control, and rehabilitation or imprisonment does not necessarily effectively cure addiction. Many inmates relapse after being released from prison. This article investigates the impact of group counseling in preparing drug inmates for release to prevent relapse, using a quasi-experimental method with a pretest-posttest control group design. The research subjects were 20 males aged 23 to 51 in Salatiga and Ambarawa prisons. The results showed that group counseling interventions significantly reduced the tendency to relapse, proving that group therapy can be implemented in prison rehabilitation programs. The DPR RI needs to oversee the implementation of Law No. 1 of 2023 concerning the Criminal Code and provide feedback to BNN RI, the Ministry of Law and Human Rights (KemenkumHAM), and the National Police (POLRI) regarding the preparation of inmates before release to prevent relapse after release.Abstrak: Penyalahgunaan narkotika masih menjadi masalah nasional yang sulit dikendalikan, dan rehabilitasi atau hukuman penjara belum tentu efektif dalam menyembuhkan ketergantungan.

Book Review: Moser, K. (2024). Fake News in Contemporary Science and Politics. A Requiem for the Real? Palgrave Macmillan
Authors: Manolescu Dan
Published: June 2024

When the conditions are right, there are ideas and concepts that ignite and burn with such intensity that they outshine any others of the same time period. Fake News in Contemporary Science and Politics presents a very good example of what its author, Keith Moser, describes as infodemic, “or the increasing inability of a large segment of the population to distinguish between reality and its ubiquitous misrepresentation on a plethora of divergent screens.” In this context, the current volume is meant to send a wake-up call regarding the consequences of this constant transmission of information ad infinitum that may affect our existence on this planet and even lead to a misinterpretation of democracy and its basic grasp on reality.
Aristoteles'in Penceresinden Adaletin Neliği: "Eudaimonia" ve Siyaset Bağlamında Bir Değerlendirme
Authors: Çiğdem İbrahim
Published: June 2024

Yaşamda hemen her alan erdem ile ilişkilidir. Özellikle iktisadi, toplumsal ve siyasal düzlemde erdemin olmasına yönelik güçlü bir inanç vardır. Bu inançla paralel bir şekilde Antik Dönemden günümüze kadar siyasal düşünceler tarihi külliyatında adil bir toplumsal düzenin ve adil bir siyasal yönetimin nasıl olması gerektiği hususu sıkça tartışılmıştır. Erdem ile siyasetin birbirinden ayrılmaz görüldüğü Antik Dönemin ünlü filozofu Aristoteles, bu bağlamda, adalet kavramına dair önemli argümanlar ortaya koymuştur. Aristoteles, adaleti, tıpkı diğer erdemler gibi, mutluluğa (“Eudaimonia”) giden yolda bir araç olarak görmüştür. Bununla birlikte, onun adalet kavramına ilişkin bazı argümanlarının, kendi içinde tutarlı gibi görünse de, ne kadar “adil” olduğu tartışmalıdır. Makalede Aristoteles’in toplumsal ve siyasal düzlemde adalet arayışına ilişkin felsefi argümanları bütüncül bir açıdan incelenmiş, konuyla ilgili genel açıklamaların ötesinde ona eleştirel bir yaklaşımla literatüre katkı sağlanması amaçlanmıştır.

Published: June 2024

Türkiye tarımında önemli bir rol oynayan endüstri bitkileri, bitkisel üretim kapsamında birçok sanayi sektörüne doğrudan veya dolaylı olarak ham madde sağlayarak ulusal gelir ve ihracata önemli katkı sunmaktadır. Bu çalışma pandemi öncesi ve pandemi sonrası Türkiye’deki bazı endüstri bitkilerine ait hasat edilen alan, verim ve üretim miktarındaki değişimlerin analiz edilmesi amacıyla yapılmıştır. Çalışmada 2012-2022 yılları arasındaki FAO ve TÜİK kayıtlarından elde edilen bazı endüstri bitkilerinin; hasat edilen alan, üretim miktarı ve verim değerlerine ait ikincil veriler kullanılmıştır. Ayrıca internet kaynakları, yerli ve yabancı kaynaklardan derlenen genel bilgiler, konuyla ilgili istatistik verilerden de faydalanılmıştır. Çalışmada endeks hesabı yönteminden faydalanılmıştır. Çalışma bulgularına göre; tarım sektöründe birçok alanda olduğu gibi endüstri bitkilerinin verim, üretim ve hasat edilen alan değerlerinin değişmesinde sebeplerden birinin de pandemi olduğu kanısına varılmıştır. Pandemi sürecinde gıda güvenliği ve kendi kendine yeterlilik konularının ön plana çıkması bazı çiftçilerin endüstri bitkilerinden gıda ürünlerine yönelmesine neden olmuştur. Yine bazı üreticilerin, yüksek belirsizlik nedeniyle endüstri bitkileri yerine daha hızlı gelir getiren veya temel gıda maddeleri üretimine yönelmeleri, endüstri bitkileri için ayrılan ekim alanlarında azalmaya neden olmuştur. Sonuç olarak; COVID-19 pandemisi, Türkiye'de endüstri bitkileri üretimini birçok açıdan etkilemiş, işgücü ve tedarik zinciri sorunları, pazar belirsizlikleri ve değişen ekim alanları, üretim ve verimlilik üzerinde belirleyici olmuştur. Bu süreçte, tarım sektörünün dayanıklılığını artırmak ve gelecekte benzer krizlere hazırlıklı olmak için tarım teknolojilerinin benimsenmesi, eğitim ve destek politikalarının güçlendirilmesi son derece önemlidir.

The nearshore reefs play several important ecosystem functions in marine environments, especially in coastal areas. Six relatively unknown nearshore reef sites were surveyed in the southern Kuantan coastal waters using the coral video transect (CVT) technique between April 2021 and September 2022 to estimate coral reef benthic components. Data analysis on coral reef benthic components indicated that these uncharted nearshore reefs have ‘fair’ coral cover with an average percentage of 39.4 % ± 17.8 in which ST 1 recorded the highest live coral cover coverage with 68.06 %. Abiotic components (sand and rock) were the second-most abundant and the coverage of dead coral was relatively low at all stations. A total of 33 coral genera were recorded in this study in which Porites, Acropora and Montipora mean percentage cover dominated most of the reef sites. Bathymetry data indicated that some of these uncharted reefs were located on submerged shoals with a depth range between 12 – 17 meters. The variation in benthic community composition observed among reef sites highlights the importance of location-specific management and conservation strategies.

Marine environment is a harsh and severe environment for a metal structure like vessel, oil rigs and port infrastructure. A regular survey or monitoring is needed to reduce a structure failure due to the corrosion. To be seaworthy, a vessel should undergo a regular survey under specified timeframe. This survey is time consuming and costly. An alternative approach is required to predict the structural integrity of a vessel. Artificial Neural Network is one of the current methods that can be used to predict the deterioration rate of a structure. Corrosion integrity of RV-Discovery was determined via plate thickness measurement, coating thickness measurement and potential measurement. The data obtained from these measurements were used in artificial neural network to predict the deterioration rate. The results indicate that the plate and coating thickness reduction percentage is within minimal range while the average potential changes show that the structure is in passivation state. It implies that the structural integrity is in a good state with no or minimal maintenance required. The prediction of deterioration rate also shows that Scaled Conjugate Gradient (SCG) training algorithm was able to predict with over 95% of confidence and low mean square error.

Across the globe, vector-borne diseases (VBD) are causes of health and economic concern, particularly for companion animals such as dogs and cats. The common clinical presentation ranges from subclinical to acute infection even a proportion with symptomatic manifestation. The diagnosis of asymptomatic animals with VBDs is quite challenging since veterinary practitioners do rely on presenting clinical signs to inform the choice of diagnostic plan. In Malaysia, blood smears (thin and thick) are employed in the diagnosis of VBDs such as babesiosis, anaplasmosis, theileriosis and trypanosomiasis. This method is readily available and inexpensive; however, the sensitivity and specificity are low as the diagnosis is strongly dependent on the experience of the examiner. Conventional polymerase chain reaction (PCR) on the other hand is used in larger veterinary clinics and hospitals in Malaysia and is only utilised when there is a suspicion of VBDs. This study attempts to compare the thin blood smear method and conventional PCR in the diagnosis of of Anaplasma phagocytophilum, A. platys, Babesia canis, B. gibsoni, Ehrlichia canis in dogs in Malaysia. Thirty clinically healthy dogs (17 males and 13 females) averaging 2 years of age were randomly selected from clinic walk-ins to screen for VBDs with both blood smear and conventional PCR. In general, the conventional PCR was 2.5 times more sensitive and specific than the blood smear in the detection of VBDs including Babesia canis, Babesia gibsoni and Ehrlichia canis in the asymptomatic sampled dogs. The detection rate for blood smears was 20% (6/30) in comparison with 50% (15/30). Therefore, it is imperative to conduct screenings for VBDs in dogs, even when they present as asymptomatic, in order to avert the oversight of potential health emergencies. Conventional PCR emerges as the recommended methodology for screening asymptomatic dogs for VBDs.

This study studies the complex relationships between maize growth, soil organic matter, and soil physico-chemcial properties, with an emphasis on biochar. It examines how soil organic matter affects pH, bulk density, Cation Exchange Capacity (CEC), porosity, and nutrient levels. Biochar and soil organic matter increase soil pH by decomposing organic anions. With biochar, increasing soil organic matter concentration reduces bulk density, improving soil structure, porosity, and water retention. By increasing Cation Exchange Capacity (CEC), biochar and soil organic matter improve soil nutrient retention and delivery, which is essential for soil fertility. As a soil organic matter component, biochar provides macro and micronutrients, boosting soil production. The study also highlights the importance of soil porosity in plant growth, with sandy soils having high porosity and leaching susceptibility and soil organic matter. However, loam soils, made of sand, clay, and silt, have a balanced porosity and soil organic matter concentration that makes them ideal for agriculture. These data show how organic matter, and biochar, affect maize growth and soil physico-chemical properties. This finding has major implications for protecting the environment and sustainable agriculture.

Water use for agricultural production in water scarcity regions requires precise irrigation water for sustainable irrigation management. The correct amount of irrigation water should be applied to ensure the survival of plants. Currently, farmers apply irrigation without considering the actual amount of the crop water requirement (ETc), which may lead to over or under-irrigation. These problems may cause water logging, crop stress, reduced yield and inefficient farm management. Durian (Durio zibethinus) is an important economic crop of Southeast Asian countries, including Thailand, Malaysia, and Indonesia. Lately, durian plantation has been increasing in Malaysia with innovative and sustainable approaches through irrigation or fertigation. The growth of durian is highly affected by water and nutrients given to the plants. This paper highlights the effect of precise irrigation through durian water requirement. Hence, this study aims to compare the difference in growth performance between existing practices (irrigation without ETc) and irrigation based on ETc. The study was conducted in the durian plantation at Sri Lalang, Kluang, Johor. There were two treatments tested on the durian, which are treatment 1 (T1) existing practice (irrigation without ETc) and treatment 2 (T2), irrigation based on ETc. The experimental design for this experiment is a Randomized Complete Block Design (RCBD) with four (4) blocks, and four trees for each treatment per block. The data collection includes the height of the tree, canopy width, girth’s diameter, node distance, leaf length and leaf weight. These data were analysed using ANOVA and LSD. Data was collected from April until November 2020. There was a significant difference in node distance from April until September. However, there were no significant differences for other growth parameters, suggesting precise crop water requirement can save water and minimize cost for the whole irrigation management.
