Abstract. Data from ozonesondes launched at ARIES Nainital (29.40° N, 79.50° E, and 1793 m elevation) are used to evaluate the Atmospheric Infrared Sounder (AIRS) version 6 ozone profiles and total column ozone during the period 2011–2017 over the central Himalaya. The AIRS ozone products are analyzed in terms of retrieval sensitivity, retrieval biases/errors, and ability to retrieve the natural variability of columnar ozone, which has not been done so far from the Himalayan region having complex topography. For a direct comparison, averaging kernels information is used to account for the sensitivity difference between the AIRS and ozonesonde data. We show that AIRS can provide quality data of ozone in the lower and middle troposphere and stratosphere with nominal underestimation (<20 %). However, in the upper troposphere and lower stratosphere (UTLS), we observe a considerable overestimation of the magnitude as high as 102 %. The weighted statistical error analysis of AIRS ozone shows higher positive bias, root mean squared error, and standard deviation in the upper troposphere of about 65 %, 65 %, and 25 %, respectively. Similar to AIRS, Infrared Atmospheric Sounding Interferometer (IASI) and Cross-track Infrared Sounder (CrIS) are also able to produce ozone peaks and gradients successfully. However, the statistical errors are again higher in the UTLS region that are likely related to larger variability of ozone, lower ozone partial pressure and inadequate retrieval information on the surface parameters. The monthly variations of columnar ozone (total, UTLS, and tropospheric) are captured well by AIRS, except the total columnar ozone, which shows a strong bimodal variation, unlike unimodal variation seen in ozonesonde and Ozone Monitoring Instrument (OMI). Increases in ozone of 5–20 % (in 2–6 km altitude) after the biomass burning and during events of downward transport (in 2–16 km altitude) are captured well by AIRS. Ozone radiative forcing (RF) derived from total column ozone matches well between ozonesonde (4.86 mW/m2) and OMI (4.04 mW/m2), while significant RF underestimation is seen in AIRS (2.96 mW/m2). The fragile and complex landscapes of the Himalayas are more sensitive to global climate change, and establishing such biases and error analysis of space-borne sensors will help study the long-term trends and estimate accurate radiative budgets.

Published: June 2022

This analysis of the K-8 statistics standards in 41 United States of America (USA) state documents that include grade level expectations (GLEs) is timely given the increased need for statistical literacy as the quantity of available data around us grows. This analysis endeavors to answer the question: What are K-8 students in the USA expected to know and be able to do with regard to statistics as represented in the state standards documents? The study was framed using the four process components outlined in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) Report: (1) formulate questions, (2) collect data, (3) analyze data, and (4) interpret results (Franklin et al., 2007). Among other findings, the analysis highlights two major types of knowledge expected in the documents, the knowledge expected to “do” each of the four processes and the knowledge expected to “understand” and/or “evaluate” the processes.
Collaborative work in statistics classes: Why do it?
Authors:   Universidade de Lisboa, Carvalho Carolina
Published: June 2022

In Portugal like in many other countries we can find statistics in the mathematics curriculum, and statistics is taught in mathematics classes by mathematics teachers until the university level. During the compulsory levels most Portuguese students learn statistics in a traditional way. In this paper, we analyse dialogues of 7th grade students during collaborative work. The main objective was to understand some benefits of this kind of work on students’ statistical reasoning. Our results suggest that collaborative work improves students’ statistical reasoning as a result of the discussions and clarifications of their ideas and resolutions but also shows that this kind of work plays an important role in supporting students’ development of positive orientations towards statistics.

The use of crude oil in the treatment of diseases is gaining popularity in several parts of Nigeria. The impact of handling and storage on the toxicity profile of the Nigeria Crude oil has not been determined. A few hepatic and renal parameters were used in this study to assess the toxicity of crude oil samples found in different parts of Nigeria.  Three different crude oil samples from Onitsha market, Lagos markets and NNPC refinery Port Harcourt were administered orally for 30 days at three dose levels (750, 1500 and 3000 mg/kg) while the control was given water (10 ml/kg). There was a rise in serum BUN of 1500 mg/kg and 3000 mg/kg for both NNPC (Groups C & D) and Lagos (Groups I & J) samples while for Onitsha, a significant rise was observed only in the 3000 mg/kg dose group (Group G). Similarly, a significant percentage rise in creatinine was observed in 1500 mg/kg and 3000 mg/kg doses for both NNPC (Groups C & D) and Lagos (Groups I & J) samples, while all doses of crude oil from Onitsha showed no significant increase. Furthermore, all doses of the three samples of crude oil showed a significant percentage increase in serum levels of AST, whereas only the 1500 mg/kg dose of crude oil from NNPC showed a significant percentage rise in the serum levels of ALT. The results of the histological studies for the liver and kidney tissues demonstrated more abnormality in NNPC and Lagos samples than in the Onitsha samples. Conclusively, crude oil from the NNPC refinery and Lagos market was more toxic than the samples from the Onitsha market. Factors likely to contribute to differences in toxicity profiles could be exposure, environmental conditions, and time.

The incidence of Sickle Cell and Rhesus Factor disorders has a considerable impact on death rates across the world. Unmarried students in the Department of Health Education at the University of Ilorin were tested on their knowledge of Sickle Cell and Rhesus Factor compatibility. The study looked at how knowledge about Sickle Cell illness and Rhesus Factor compatibility varied according to gender, (ii) academic level, (iii) age, and (iv) religion. The study used a survey-style descriptive research approach. The study's participants were single students in the Department of Health Education. A multi-stage sampling process was used to choose 200 respondents for the study. Data was collected using a validated structured questionnaire with a reliability value of 0.72. The data was analyzed using descriptive statistics of percentages, and inferential statistics of independent test and Analysis of Variance (ANOVA) at the 0.05 alpha level. Among the findings were that:
1. The level of knowledge of sickle cell was moderate.
2. The level of knowledge of Rhesus factor compatibility was also moderate.
3. There was no statistically significant difference in the knowledge of sickle cell based on gender (t{198} = 1.21, p>0.05).
4. There was no statistically significant difference in the knowledge of sickle cell based on age range (t{198} = 1.218, p>0.05).
5. There was no statistically significant difference in the knowledge of sickle cell on religion (t{198} = 1.491, p>0.05).
The study revealed, among other things, that the students' understanding of Sickle Cell and Rhesus Factor compatibility was moderate. As a result, it was suggested that students be educated about the consequences of Sickle Cell and Rhesus Factor incompatibility through health symposiums, public announcements, and social media, as well as the various ways in which it can be avoided, to aid in the development of their knowledge and to assist groups and individuals in making informed decisions in such health matters.

Digital Marketing Devices (DMD) as part of disruptive technology in marketing related activities is described as the use of the Internet, mobile devices, social media, search engines, and other channels to reach consumers. Arguably, TOE model is wildly recognized as a model for adoption/acceptance of technology related studies, its focus is largely on firm’s acceptance neglecting the customers or individual acceptance. Secondly, there has not been any scientific evidence proving how TOE influences the adoption of digital marketing devices at individual level. The objective of the study is to propose a holistic model that will integrate individual behavior in the existing TOE model for acceptance of DMD at the individual level. Acknowledging the existing model of TOE and theory of planned behavior, the study incorporated behavioral in the TOE model to develop Technology- Behavioral -Environment (TBE). The essence is to reflect individual behavior on the acceptance of innovation technology. The proposed framework provided a robust dimension to investigate individual-level technology acceptance.

Published: June 2022

Radioactive isotopes of rare earth elements have effective nuclear-physical properties and are promising for the development of new therapeutic radiopharmaceuticals. Rare earth elements (REE) include 17 elements of the secondary subgroup of group III of the periodic table of chemical elements of D.I. Mendeleev with atomic numbers 21, 39, 57, 58–71: scandium, yttrium, lanthanum and 14 lanthanides. Some radioactive isotopes of these elements are already used in medicine, as a radioactive component of approved medicines, for example, the isotopes of 153Sm and 177Lu, and for some the possibility of their use in medicine is only being studied. Thus, the isotope scandium – 47Sc is being studied as a potential radioisotope for cancer diagnosis, holmium – 166Ho as an isotope for radiosynovectomy and brachytherapy, praseodymium – 142Pr is promising for brachytherapy. The ability of rare earth elements to form chemical bonds with organic molecules, including peptides of natural and synthetic origin, is the basis for the development of new drugs for targeted therapy of breast and prostate cancer, neuroendocrine tumors, disseminated lung cancer and other types of diseases. To determine the list of the most promising for irradiation at the rector of the WWR-K REE in order to develop radioactive isotopes, an assessment of the ways of developing radioactive isotopes and an analysis of their nuclear physical characteristics according to literature data was carried out. Isotopes such as: 166Ho, 165Dy, 90Y, 175Yb, 153Sm, 177Lu, 147Nd, 170Tm, 159Gd and 141Ce can be used in the treatment of oncological diseases. This research work makes it possible to evaluate the possibility of obtaining REE radioisotopes by reaction (n, γ) at the WWR-K reactor, and reflects the prospects for using these isotopes in the development of new-generation radiopharmaceuticals for the treatment of oncological diseases.
Antonio Gramsci’nin Hegemonya Kavramının Uluslararası İlişkiler Disiplinine Girişi ve Yorumlanması
Authors: EKREN Alican
Published: June 2022

Robert W. Cox’un Gramsci’den alarak uluslararası ilişkiler disiplinine uyarladığı “hegemonya” kavramı, uluslararası sistem içinde yer alan devletlerin yanında devlet dışı aktörlerin de yer aldığı, rızaya dayalı bir ilişki biçimi olarak tanımlanmaktadır. Cox’a göre hegemonya, yalnızca devletler arası ilişkiler ile anlaşılamaz; çünkü, hegemonya, devletlerin sosyal sınıfları ile bağlantı kurmasını sağlayan, uluslararası düzeyde bir üretim modeli üzerine kuruldur. Cox’un uygulamaya çalıştığı bu yaklaşım, sosyal güçler, devlet yapısı ve devlet dış politikası arasındaki ilişkiyi ortaya koymayı amaçlamaktadır. Robert W. Cox’un hegemonya kavramı çerçevesinde inşa etmiş olduğu kuram, yeni-Gramşiyan perspektifi etkileyen ve besleyen bir metedollojiye sahiptir. Bu metedoloji, bilhassa belirsizlik dönemlerinin adlandırılması ve gelecek ihtimaller hakkında düşünülmeyi kolaylaştıran olanaklara sahiptir.

Bu çalışma, Robert W. Cox’un Gramsci’nin hegemonya kavramını uluslararası ilişkiler disiplinine katarken kullandığı metodlardan bahsederken, aynı zamanda uluslararası ilişkiler teorilerinin hegemonya görüşlerini de açıklamaktadır. Çalışmanın asıl açıklamaya çalıştığı sorunsal ise Cox’un hegemonya yaklaşımının günümüz uluslararası sistem içerisindeki geçerliliğidir.

The health emergency is compelling us to adopt new habits, including education-related practices. Therefore, it may be worth considering targeted teaching strategies and their future development. Current research in e-learning and technology-supported teaching has recently developed in an attempt to identify possible future transformations at all levels of education.This paper focuses on tertiary-level education and describes a study on educators’ views on courses delivered via Moodle during the pandemic and on the most commonly used pedagogical models.Using a case study on methodology, the author analyses some possible forms of online education, from the most basic, to those implemented through a combination of digital activities and resources, and their application at the University of Urbino (Italy). Data were collected by means of a questionnaire administered to 231 university teachers during the first year of the pandemic.The findings suggest that there is a good basic tendency to use technology but also inevitable stress that is however combined with an underlying sense of satisfaction. The educators’ technological skills, their tools, and the advice offered by the institution appear satisfactory, while students seem to have found some basic difficulties in accessing online lessons. The most commonly used didactic practices are sharing files via Moodle, using web conferencing software and text chats during lessons. Finally, future developments are to be expected as lecturers express their willingness to continue using the same technological resources that they have found most effective during the COVID-19 emergency.

Published: June 2022

Introduction: Pregnant women are at high risk for coronavirus because of their physiologic and immunologic changes. Hence, preventive measures are essential as they prevent higher mortality. However, there is a paucity of evidence on the knowledge, attitude, and practice of the prevention of coronavirus in the study area. Thus, this study assesses knowledge, attitude, practice, and associated factor towards coronavirus prevention among pregnant women is crucial. Methods: An institution-based cross-sectional study was employed among 549 pregnant women from June 1 to 30, 2021. A multi-stage sampling technique was used to select the study participants. Data were collected using an interviewer-administered structured questionnaire. The software Epi-data version 4.6 and SPSS version 23 were used for data entry and analysis, respectively. Binary logistic regressions (bivariable and multivariable) were performed to identify statistically significant variables. Adjusted odds ratio with a 95% CI was used to declare statistically significant variables on the basis of a p-value < 0.05 in the multivariable logistic regression model. Results: Of the overall sample required (N = 549), 538 pregnant women with 98.0% response rate. The prevalence of good knowledge was 67.3% (95% CI: 63.0, 71.0), a desirable attitude was 43.0% (95% CI: 42.6%, 50.6%), and good practice was 51.6% (95% CI: 47.0, 55.9%) towards coronavirus prevention. Urban residents (AOR: 2.12, 95%, CI: 1.40, 3.20), unemployed husbands (AOR: 0.39, 95%, CI: 0.25, 0.62) and less than 3000 Ethiopian birr family income (AOR: 0.53, 95%, CI: 0.32, 0.85) were found to be statistically significant with knowledge of coronavirus, where as participants’ age (32–38 years) (AOR:2.24, 95%, CI:1.02, 4.26), participants’ education( AOR:2.33, 95%CI:1.19, 4.55), husbands’ education (AOR:2.88(95% CI:1.35,4.54),and husband’s occupation (AOR: 1.94, 95%, CI: 1.24, 3.03) were also significantly associated with the practice of coronavirus prevention. Conclusions: The findings have indicated that the prevalence of the study participants who had good knowledge, attitudes, and practices towards prevention of coronavirus were low compared to developing countries. Hence, healthcare providers should provide health education to pregnant mothers during antenatal care visits and disseminate leaflets regarding the COVID-19 preventive measures.

The present study was conducted to detect possible chemicals (phytoconstituents), and investigate antioxidant, antimicrobial and thrombolytic activities of the extract of Aphanamixis polystachya (stem bark). Phytochemical screening was carried out using the standard test methods of different chemical group. For investigating the antioxidant activity, two complementary test methods namely DPPH free radical scavenging assay and total phenolic content determination were carried out. For the evaluation of in Vitro antimicrobial activity, disc diffusion method, and to determine the thrombolytic activity, the method of Prasad et al., 2007 with minor modifications were used. The bark extracts were a rich source of phytochemicals. In DPPH free radical scavenging test, the Carbon tetra chloride soluble fraction showed the highest free radical scavenging activity with IC50 value 19.86 µg/ml. while compared to that of the reference standards ascorbic acid. Aphanamixis polystachya was also found as a good source of total phenolic contents. Moreover, the extracts revealed broad spectrum antimicrobial activity at the concentration of 400 µg/disc. By comparing with the negative control the mean clot lysis % was significant (p value <0.0009). Therefore, further studies are suggested to determine the active compounds responsible for the biological activities of the plant extracts.

The present study was conducted to assess the cytotoxicity, thrombolytic, anthelmintic and antioxidant activity of mehanolic extract of Litsea monopetala (Family: Lauraceae) leaves in laboratory using in vitro methods. Cytotoxicity test was done by brine shrimp lethality bioassay where the extract concentration was 400, 200, 100, 50, 25, 12.5, 6.25, 3.125, 1.5625, 0.78125 (µg/ml). In vitro thrombolytic activity of Litsea monopetala was performed by clot lysis method using extract concentration 2.5, 5, 10 and 20 (mg/mL) in saline water. Anthelmintic activity test was done by using adult earthworms where 10, 20, 40, 60, 80 (mg/ml) extract concentration were used. Finally antioxidant activity was determined by total phenolic content determination using Folin-Ciocalteu reagent. The Litsea monopetala extract showed cytotoxic activity against brine shrimp nauplii and LC50 value was 41.05(µg/ml) and the investigated thrombolytic activity in our research was 9.52, 9.49, 13.64 and 17.50 % respectively as % of clot lysis. The paralysis time were at 76.75 min, 60 min, 51.75 min, 44.5 min and 64.5 min and death were at 90.50min, 63.75min, 55.50min, 44.75min and 71min. respectively. The Litsea monopetala extract displayed significant antioxidant activity which was 20.75 (mg of GAE / gm) of extracts. The activities observed could be attributed to presence of some of the phytochemicals which have been related with cytotoxic, thrombolytic, anthelmintic and antioxidant property.

Quality in higher education academic programs in general and in particular engineering education programs is one of the essential issues in the process of developing and modernizing the education system within the vision of the Kingdom of Saudi Arabia 2030. The development of engineering programs outcomes is also one of the challenges facing engineering colleges in Saudi universities. To achieve a comprehensive educational quality practice that leads to bridge the gap between engineering education outcomes and labor market requirements, engineering programs outcomes should be developed in line with the changes of the modern era and the requirements of the accelerated technological labor market. This target is one of the basic and strategic pillars for achieving this ambitious vision through the effective role of Saudi universities in this context. In the present study, the development of learning outcomes in the previous period for engineering education programs is reviewed through the National Center for Academic Assessment and Accreditation (NCAAA) as well as through the Accreditation Council for Engineering and Technology (ABET). A model for developing study plans and redesigning various engineering programs to achieve a distinct level of the quality of engineering education is presented through the National Transformation Program 2020. Through this philosophy of change to formulate learning outcomes for engineering programs and their diversity, the updated assessment methods have been reviewed and proposed to measure those outcomes in a distinct way. This study will offer a guide that helps the teaching staff to choose the most appropriate assessment methods with setting the priorities of the measurement methods for each educational outcome of the curriculum. The presented scientific paper provides a model for continuous evaluation plans of the educational process in engineering programs to achieve the goals of engineering programs that seek to distinguish their graduates and raise their productivity and increase their competitiveness in a way that suits the nature of the current labor market.

Published: June 2022

Environmental pollutants of oil and gas flaring are fast emerging major threats to the global health communities and environmental authorities; and also, an important source of morbidity and mortality. From purposively selected 94 volunteers exposed to toxic oil and gas flared pollutants in Ogoni land, Niger Delta, Nigeria, serum samples were used to evaluate possible association between non-communicable diseases (NCDs) and insulin resistance using C-peptide and Insulin kits. Volunteer’s age ranged 18 to 50 years, and were exclusively females resident consistently, in the various communities, in the order of 10 years and above. When compared to control, the outcomes of this study indicated high levels of insulin resistance, insulin, beta cell function, blood glucose of 78%, 76.2%, 71.6%, 52.5%with corresponding decrease in connecting peptide value of 43.2% was associated within creases in various physio-metabolic risk factors including low density lipoprotein, triglyceride, total cholesterol, high density lipoprotein and body mass index of 64.9%, 62.4%, 60.6%, 52.5% and 52% respectively in the exposed population to oil and gas flaring pollutants. Meanwhile, the prevalence of cardio-metabolic risk factor ratio (TG/HDL-C) was higher for the exposed population (63.6 %.) than the control (36.4%); while the prevalence of hyperinsulinemia/insulin resistance showed age and time dependent increase of exposure. This study validates both insulin resistance and toxic pollutions of oil and gas flaring as sensitive indicators of multiple metabolic abnormalities. Further, the inherent capacity of toxic oil and gas flared pollutants to elicit detectable pathologies in various tissues and organ induced-insulin resistance, might plausibly be the mechanist-link, in metabolic derangements, in the development and progression of a number of chronic non-communicable diseases, including diabetes, dyslipidaemia, hypertension, cardiovascular diseases, cancers, respiratory diseases, obesity and complications and disabilities and even death.

Analisis Resiko Usaha Pembesaran Lele Sangkuriang Probiotik Dan Non Probiotik (Study Kasus Usaha Lele Bapak Wahyu) Di Desa Karang Binangun II BMR OKU Timur
Authors: Munsiarum  , Wiwiek Tri Setyarini
Published: June 2022

The catfish farming business is a fairly developed business in the fisheries sector of East OKU district. Enlargement of catfish on limited land with high stocking density and poor feed management will worsen pond water conditions due to accumulation of organic matter that is toxic to catfish which causes stress and causes various diseases. Currently, probiotics are being used in fisheries for disease prevention efforts. The probiotic application itself gave birth to different attitudes and opinions for sangkuriang catfish rearing actors in Karang Binangun II Village, a stronghold that responded positively to revealing that real results had been obtained, in fact reducing production costs and boosting productivity. Meanwhile, from the camps that disagree, arguing is only wasteful and detrimental.

The average cost incurred for probiotic sangkuriang catfish enlargement per 100 m² in one production cycle is Rp. 16,017,705 with an average total receipt of Rp. 21,098,500 so that the average income of probiotic sangkuriang catfish enlargement is Rp. 5,080,795. while the average cost incurred on non-probiotic sangkuriang catfish enlargement per 100 m² in one production cycle is Rp. 16,228,200 with an average total revenue received of Rp. 19,239,500 so that the average income for raising sangkuriang catfish non probiotics is Rp. 3,011,300.

The cost risk of probiotic sangkuriang catfish rearing the coefficient of variance is 0.0063 while nonprobiotic sangkuriang catfish rearing the coefficient of variance is 0.0277, this is due to the large production costs that must be incurred by non-probiotic sangkuriang catfish rearing farmers, such as fertilization costs, liming costs , the cost of immunostimulants, and the cost of feed.

For the production risk of probiotic sangkuriang catfish rearing with a coefficient of variance of 0.0048, while the non-probiotic sangkuriang catfish rearing with a variance coefficient of 0.0729 The results of the analysis show that the production risk of probiotic sangkuriang catfish rearing is smaller than that of nonprobiotic sangkuriang catfish rearing. this is due to the large production obtained on the enlargement of probiotic sangkuriang catfish.

On the income risk of probiotic sangkuriang catfish rearing the coefficient of variance is 0.14 while on non-probiotic sangkuriang catfish rearing the coefficient of variance is 0.31. The results of the analysis show that the income risk of probiotic sangkuriang catfish enlargement is smaller than non-probiotic sangkuriang catfish enlargement, this is due to the low production cost of probiotic sangkuriang catfish with high production yields so that the income obtained on probiotic sangkuriang catfish enlargement is high.

Fully residential schools (FRS) or boarding schools in Malaysia produce quality candidates with towering personalities. This study seeks to explore the choice of career as well as the parents and gender influences on the career as a teacher among top FRS students in Malaysia. A survey design, which is mainly quantitative in nature, was used in this empirical study. A self-designed questionnaire was used in collecting data from 305 participants from three top FRS in Malaysia. This study revealed that only 6.2% of students selected 'teacher' as a career of choice. Other respondents opted for different professions such as medical doctors, engineers, and scientists. Of the students who chose ‘teacher’ as their career of choice, 31.6% have one or both parents from a teaching background. The study also found that the influence of gender on the career as a teacher was not significant with t (303) = 0.446, p = 0.656. Several recommendations were made. This study suggests further increasing the FRS students' exposure to the teaching career with the recommendations proposed.

Nurses are an integral part of the health care system. Studies have shown that when hospitals and other health facilities have the right number of nurses, it improves patient safety, mortality rates, and overall patient outcomes. The lack of nurses is a complex problem with several causes. There are many aspects to play, from the aging population of nurses, fatigue from work overload, stressful working environment, low wages and work dissatisfaction.  The combination of these factors causes a shortage of nurses and causes them to grow over time. The mental and physical pressure on nurses can increase their burnt out and is the main reason for the hectic retraction of nurses from their professions. This literature review is discussing the main reasons for the nursing shortage, and its negative impact on health systems and patient care, then finally discusses the solutions for this problem from the literature.

Medical imaging is extremely important in the domain of medicine. Image classification is now utilized to distinguish aberrant tissues from healthy tissue in brain imaging. The brain tumor is identified from MRI images by using some classification techniques, where the area of the tumor as well as the tumor size is detected. Automatic tumor detection using brain MRI is efficient and time- saving, assisting the neurologists in diagnosis.  Tumors can increase the risk of  cancer,  which  is  the  most  common  cause  of  death  or major cause of mortality worldwide. To detect brain tumors at the moment, effective automation of tumor detection is essential. Marker based Watershed algorithm is a typical segmentation technique which is used for identifying brain tumors. For brain tumor detection, we performed marker based watershed classification on MRI images with the use of gray scale images, then   by noise removal and morphological operations. The steps in the methodology are as follows:  Gray-level and sharpening was used in the pre-processing, and the image was segmented using thresholding as well as the marker based watershed algorithm, and the CNN was used for classifying the images. Finally, the tumor's location and size were determined.

Magmatic Ni-Cu-platinum group element (PGE)-Te mineralization in the Gondpipri mafic-ultramafic layered intrusion of ca. 3323 ± 74 Ma age, western Bastar craton, central India, is one of the most prospective exploration targets for magmatic sulfides in India. The Gondpipri layered intrusion is divided into two distinct groups of rocks based on their mineralization potential, which include (1) mineralized layered gabbro and pyroxenite and (2) a barren olivine gabbro intrusion. The host rocks show Cu + Ni concentrations up to 5,000 ppm with a Cu/Ni ratio <1 and all PGE values between 0.1 and 1.1 ppm. Mineralization occurs in two modes: type I mineralization occurring as blebs, specks, and dissemination and type II mineralization occurring as stringers and minor veins. The geochemical data suggest that the parental magma of the host rock was generated at depths between spinel and garnet peridotite mantle source regions and subsequently modified by assimilation fractional crystallization (AFC) of the continental crust. High large ion lithophile elements, Th/Yb ratios of the studied rocks, and Sm-Nd isotope studies are consistent with a depleted mantle source. The geochemical proxies such as Th versus Ba/Th and (Ta/La)PM versus (Hf/Sm)PM and higher Sr/Nd (2.21–82.58) ratios indicate involvement of fluid-related subduction metasomatism and enrichment processes in an island-arc tectonic setting.

Mineral assemblages and textural relationships between platinum group minerals (PGMs) and base metal sulfides suggest that sulfide-silicate liquid immiscibility was brought about by the precipitation of magnetite/Cr magnetite resulting in sulfide saturation in the melt by decreasing S solubility. Sulfur isotope compositions (δ34S: 1.61–3.30‰) and Sm-Nd geochemistry suggest that the sulfur was added in the tholeiitic magma by magmatic process. Crustal contamination played a significant role in sulfide saturation and in bringing about PGE and Te, As, Bi, Sb, Se (TABS) mineralization. PGM-NiTeBi developed at relatively low temperatures, whereas moncheite (PtPd)Te2 and merenskyite (PdTe) were formed at 650°C. The identification of Ni-Cu-PGM-Te in the margin of the western Bastar craton boosts deeper subsurface exploration.
