Authors: Kulikova M. M. , Solomay T. V. , Semenenko T. A.
Published: March 2022

At the moment, the clinical differences between primary acute and reactivation of chronic infection caused by Epstein-Barr virus (EBV) have not been fully studied.The aim is to identify clinical and laboratory differences between primary acute and reactivation of chronic EBV infection in children aged 0—17 years.Materials and methods. A systematic review and meta-analysis of publications was carried out, which were searched through the bibliographic databases PubMed, Cyberleninka, eLibrary, as well as using the Researchgate scientific network. The total number of keyword search results was 1,830 publications, of which 26 were included in the study according to the results of the selection. 1318 cases of active EB infection were subjected to meta-analysis, including 917 cases of acute primary and 401 cases of reactivation.Results. Distinctive signs of primary acute EBV infection are fever, generalized lymphadenopathy, enlargement of cervical lymph nodes, acute tonsillitis, exanthema, excess of ALT reference values, leukocytosis, the presence of atypical mononuclears. With the reactivation of chronic EBV infection, the clinical manifestations are  less pronounced, but in 24% of cases the disease is accompanied by the development of interstitial pneumonia. Characteristic signs are hypertrophy of the lymphoepithelial pharyngeal ring and thymomegaly, not described in primary acute infection.Conclusion. The revealed clinical and laboratory differences between primary acute and reactivation of chronic EBV infection in children aged 0—17 years can be used for differential diagnosis of these conditions.
Common Institutional Blockholders and Reporting Practices: Evidence from Accounting Comparability
Authors: Peng Qiyuan , Yin Sirui , Zhang Rui-Zhong
Published: March 2022

SYNOPSIS

This study investigates whether common institutional blockholders (common owners) affect the accounting comparability of their portfolio firms. We document that accounting comparability between a pair of industry peers increases with common ownership presence and intensity. Common owners’ demand for comparability is more pronounced (1) when the firm pairs have higher operating uncertainty, (2) when their information environment is opaque, and (3) when they weigh more within the common owners’ portfolio. To address endogeneity concerns, we exploit financial institutions mergers as quasiexogenous shocks to common ownership. Difference-in-differences tests confirm the positive association between common ownership and accounting comparability. We conclude that common owners are important capital-market participants that create a demand for and have a significant impact on accounting comparability. To the extent that achieving higher comparability is an important goal in standard setting, our study has implications for standard setters and regulators evaluating the determining factors of accounting comparability.

When Adipose Tissue Lets You Down: Understanding the Functions of Genes Disrupted in Lipodystrophy
Authors: Rochford Justin J.
Published: March 2022

Lipodystrophy syndromes are conditions in which the adipose tissue mass of an individual is altered inappropriately. The change in adipose mass can range from a relatively modest and subtle redistribution in some individuals with partial lipodystrophy to a near-complete absence of adipose tissue in the most severe forms of generalized lipodystrophy. The common feature is a disconnection between the need of the individual for a safe, healthy lipid storage capacity and the available adipose mass to perform this critical role. The inability to partition lipids for storage in appropriately functioning adipocytes leads to lipid accumulation in other tissues, which typically results in conditions such as diabetes, dyslipidemia, fatty liver, and cardiovascular disease. Several genes have been identified whose disruption leads to inherited forms of lipodystrophy. There is a link between some of these genes and adipose dysfunction, so the molecular basis of disease pathophysiology appears clear. However, for other lipodystrophy genes, it is not evident why their disruption should affect adipose development or function or, in the case of partial lipodystrophy, why only some adipose depots should be affected. Elucidating the molecular functions of these genes and their cellular and physiological effects has the capacity to uncover fundamental new insights regarding the development and functions of adipose tissue. This information is also likely to inform better management of lipodystrophy and improved treatments for patients. In addition, the findings will often be relevant to other conditions featuring adipose tissue dysfunction, including the more common metabolic disease associated with obesity.
Keeping It Local in Metabolic Disease: Adipose Tissue Paracrine Signaling and Insulin Resistance
Authors: Kahn Darcy E. , Bergman Bryan C.
Published: March 2022

Alterations in adipose tissue composition and function are associated with obesity and contribute to the development of type 2 diabetes. While the significance of this relationship has been cemented, our understanding of the multifaceted role of adipose tissue in metabolic heath and disease continues to evolve and expand. Heterogenous populations of cells that make up adipose tissue throughout the body generate diverse secretomes containing a mosaic of bioactive compounds with vast structural and signaling capabilities. While there are many reports highlighting the important role of adipose tissue endocrine signaling in insulin resistance and type 2 diabetes, the direct, local, paracrine effect of adipose tissue has received less attention. Recent studies have begun to underscore the importance of considering anatomically discrete adipose depots for their specific impact on local microenvironments and metabolic function in neighboring tissues as well as regulation of whole-body physiology. This article highlights the important role of adipose tissue paracrine signaling on metabolic function and insulin sensitivity in nearby tissues and organs, specifically focusing on visceral, pancreatic, subcutaneous, intermuscular, and perivascular adipose tissue depots.

Building A Synergy Between The Halal Industry And The Green Industry In The Maqasid Syari'ah Review As The Basis Of Islamic Economics
Authors: Fageh Achmad
Published: March 2022

Industrial estates are usually reflected in the existence of a sure standardization. The halal industry gave birth to "Halal supply chain management," starting with halal standards procurement, manufacturing, distribution, and logistics. The green industrial area was first born by prioritizing environmental sustainability, namely efficiency in using renewable energy, environmentally friendly substitute raw materials, and waste treatment. So far, there has not been continuity seen in the Policy, so the concept of Maqasid Sharia as the basis of Islamic economics, which prioritizes "halalan thoyyiban" or halal and suitable, has not been used as a foundation to synergize the goodness of each industrial area so far. This research offers a concept of halal and environmental sustainability, which is reflected in the following industry supply chains. (1). Procurement of goods in a halal manner with environmentally friendly product raw materials criteria. (2). Manufacturing process by prioritizing the use of renewable energy. (3). Processing of waste products (gas, liquid and solid) to not damage the surrounding environment. (4). Halal Logistics and Distribution. So that what is contained in Maqashid Syariah can be implemented in this new concept

Published: March 2022

Infections with bovine viral diarrhea virus (BVDV), bovine alphaherpesvirus 1 (BoHV-1), and bovine parainfluenza virus type 3 (BPIV-3) cause diseases in cattle with serious economic consequences worldwide. The objective of the present study was to determine of herd-level and animal-level BVDV, BoHV-1, and BPIV-3 seroprevalence, and evaluate some of the associated risk factors on farms in Qazvin province, Northwestern Iran. A total of 1036 cattle in 16 herds were randomly selected, and their serum samples were tested to detect antibodies to these viruses in a cross-sectional study over 2 years. The results showed the seroprevalence of BVDV, BoHV-1, and BPIV-3 was 100%, 56.3%, and 100% at herd-level and 55.1%, 5.1%, and 95.2% at animal-level, respectively. Statistical analysis revealed that the farm was a strong risk factor for all the studied viruses, while the year was determined as a risk factor for only BVDV (P<0.001). The seroprevalence of BVDV and BPIV-3 was significantly (P<0.01) affected by season. The proportion of seropositive cows increased with age for BVDV and BoHV-1 (P<0.001). Concurrent infection was the highest in mixed infections with BVDV and BPIV-3 (53.2%), and there was a positive correlation between BVDV and BoHV-1 seropositivity (R2= 0.106, P<0.001). The present study shows that infections of BVDV and BPIV-3 are common in cattle in Northwestern Iran and which implies the need to implement control programs to reduce the risk of the spread of these viruses.

Published: March 2022

Haplotypes of candidate genes namely: apoptotic protease activating factor 1 (APAF1 p.Q579X or HH1), glycinamide ribonucleotide formyltransferase (GART or HH4), structural maintenance of chromosomes 2 (SMC2 or HH3), and haplotype cholesterol deficiency (HCD) genes associated with recessive fertility defects (loss of fertility) were investigated in imported Canadian Holstein cows reared at “Medeu Commerce” LLP breeding farm in Kazakhstan. The genotypic profiling of the APAF1/HH1, GART/HH4 fertility haplotype carriers was carried out by PCR-RFLP methods using BstC8I and Tru9I and MseI, while the genotypic profiling of the SMC2/HH3, and HCD fertility haplotype carriers was carried out using our own primer designed by internal primer marker methods. The study revealed that the PCR-RFLP diagnostic markers APAF1/HH1 and GART/HH4 for recessive fertility defects were monomorphic in the Canadian Holstein cows investigated. However, the diagnostic markers SMC2/HH3 and HCD fertility haplotype carriers (our own design diagnostic markers) were polymorphic, with frequencies of 3% and 11%, respectively, in the investigated Canadian Holstein cows. The study concluded that genetic monitoring of recessive fertility defects enables the timely identification of carriers of harmful lethal mutations, and control of the fertility haplotype elimination process.

Published: March 2022

The sustainable development of the national economy is mainly due to the balanced and steady development of its regions. The vast territory of Russia led to the formation of federal districts, which present a unity of the certain territories, on which relatively coordinated mechanisms of territorial development are formed, taking into account the socio-economic characteristics of the regions that are part of macroregions - federal districts. There arises an applied scientific interest in studying the general trends and strategic priorities for the development of a particular federal district, which influence the formation of development prospects for the subjects of the federation. The key socio-economic indicators of the development of the Ural Federal District have been analyzed, the structural and dynamic features of the regions included in its composition have been defined. The strategic priorities of the territorial development of the Ural Federal District are identified, which are detailed in the regional strategies for long-term socio-economic development. Based on the analysis of the territorial specifics of the socio-economic development of the Yamal-Nenets Autonomous Okrug, its significance in the development of the macroregion is determined, and the most acute problems of economic and social development are identified. Based on the results of the SWOT analysis, the Yamalo-Nenets Autonomous Okrug was assessed in three main areas (groups of factors): parameter “Person”, parameter “Economy”, parameter “Space”. MatFigs of the SWOT-analysis are illustrated for the priority areas under consideration, which present the factors, strengths and weaknesses, opportunities and threats of the region. The priority areas for the development of the raw and non-resource sectors of the regional economy of the okrug were identified, strengthening its balanced and progressive development.
Mechanisms and tools for managing development of logistics infrastructure of seaports in Caspian region
Authors: Volynskiy Ilya Aleksandrovich
Published: March 2022

Development of the logistics infrastructure of the seaports in the Caspian region is conditioned by their geographical location in the south of Russia and by high transit potential on the Trans-Caspian route of the international transport corridor North-South. The lack of inter-organizational coordination, as well as the limited investment opportunities of sea terminal operators do not allow to compete with the transnational transport and logistics companies engaged in foreign trade transportation along the vectors “West-East” and “North-South”. Increasing the competitiveness of the seaport logistics operators in the Caspian region can be possible as a result of the development of a mechanism that coordinates the interaction of transport and logistics services market entities and the state based on the centralization of logistics infrastructure development management functions at the macro-, meso- and micro levels. The subjects of management are defined: a single operator at the federal level, an information and analytical center of the port special economic zone of the Astrakhan region at the regional level and a logistics coordinator as a structural subdivision of a Single operator in seaports. Management technologies and tools are presented, management objects at each level are specified. The business process “management of the centered logistics system of the seaport” has been developed to coordinate interactions with the allocation of the subprocess “management of logistics infrastructure development projects”, which allows regulating the sequence and content of subprocesses, implementation tools, incoming and outgoing information flows. The operation of the interaction mechanisms between the entities managing the development of the seaport logistics infrastructure in the Caspian region is illustrated.

Authors: Khadijah Ute Lies Siti , Novianti Evi , Anwar Rully
Published: March 2022

The media played a central role in communication between people, including religious matters. In religious tourism, there were scouting activities between the committee, ustadz, and congregation in the context of worship that was carried out well. The most prominent in this religious tourism was the pilgrimage and umrah. Thus, there were many Hajj and Umrah communities in a Muslim-majority country like Indonesia. This study aims to determine the role of social media in religious tourism guidance and marketing activities. This study used a micro-sociological analysis of qualitative data from activities at one of the Hajj and Umrah guidance centers in Bandung, Indonesia. Using social network analysis, it was found that social media’s role was essential to disseminate information between Hajj and Umrah guidance institutions and their congregations. The use of Facebook for the profile of the guidance institution was beneficial for pilgrims to understand the various opportunities and obstacles that exist in the Hajj/Umrah pilgrimage. WhatsApp was the most frequently used to communicate interactively with the congregation so the clerics and committees. Social media is quite helpful in marketing when the assembly connects with friends and family in telling their experiences when worshiping in Mecca and Medina in Saudi Arabia.

Published: March 2022

Two residents of Depok City, West Java, were confirmed as the first Covid-19 patients in Indonesia on March 2, 2020. This global pandemic has wreaked havoc on many facets of human life, especially slum environment in Depok City. Slum settlements are associated with dense populations, small streets, and disorganized housing structures, and all of which contribute to the high spread of Covid-19. In Depok Village, which is classified as a slum settlement, the number of Covid-19 case is lower than in Mekarsari Village, which is neither slum nor tend to be luxury. This study uses qualitative methods and research sources are from field observations and comparisons with previous studies which are contradictory. The theory used as a guide for this writing is Ekistics, Doxiadis. According to the findings of this study, the low number of COVID-19 cases in slum settlements can be reduced, one of the factors is the impact of improved environmental infrastructure. The Covid-19 Alert Village performance, the social community and public health also play critical roles in assisting people in their efforts to avoid the spread of Covid-19. The active participation of all members of society is the most important factor in preventing Covid-19 spread and transmission. The findings of this case study are not intended to generalize the phenomena that occur in the community, but this is an effort to evaluate and introspect on programs and policies that will be, are being, and have been performed by the local government in collaboration with the community.

Published: March 2022

No Billag – in der Schweiz ist die Debatte um die Notwendigkeit und Finanzierbarkeit des öffentlich-rechtlichen Rundfunks neu entbrannt. Eng damit verbunden sind die Fragen nach dem Public Value der SRG SSR und dem Aspekt, wie viel Schweiz tatsächlich im Schweizer Fernsehen steckt. Basierend auf einer inhaltsanalytischen Sekundäranalyse der Stichprobe aus dem Jahr 2017 der kontinuierlichen Fernsehprogrammforschung in der Schweiz, wird in diesem Beitrag die Darstellung der Schweiz und des Schweizer Volkes in Bezug auf einerseits die Repräsentation in den Fernsehprogrammen der SRG SSR und andererseits hinsichtlich der Verantwortung der Medienproduktion diskutiert. Die Ergebnisse zeigen, dass die Schweiz in informierenden Genres (z. B. Nachrichten) eine wichtige Rolle spielt, während in fiktionalen Inhalten (z. B. Serien, Filmen) nur selten auf die Schweiz Bezug genommen wird. Hinzu kommt, dass fiktionale Inhalte der SRG SSR häufig von internationalen Produktionsfirmen, insbesondere aus den grossen Nachbarländern der Schweiz, verantwortet werden.
No Billag – in Switzerland, the debate about the necessity and financial viability of public broadcasting has been sparked anew. Closely linked are questions about the public value of the SRG SSR and how much of Switzerland is actually portrayed on Swiss television. Based on a secondary analysis of the 2017 data set of the continuous Swiss content analysis study, this paper discusses the representation of Switzerland and the Swiss people in terms of representation in television programmes of the SRG SSR and in terms of media production. Results show that Switzerland plays an important role in informational genres (e. g., News), while in fictional content (e. g., series, movies) references to Switzerland are scarce. Additionally, fictional content broadcast by the SRG SSR is often produced by international production firms, with preferences for content from Switzerland’s next-door-giant neighbours.
Construction of Regular Non-Atomic Strictly-Positive Measures in Second-Countable Non-Atomic Locally Compact Hausdorff Spaces
Authors: Bentley Jason
Published: March 2022

This paper presents a constructive proof of the existence of a regular non-atomic strictly-positive measure on any second-countable non-atomic locally compact Hausdorff space. This construction involves a sequence of finitely-additive set functions defined recursively on an ascending sequence of rings of subsets with a set function limit that is extendable to a measure with the desired properties. Non-atomicity of the space provides a meticulous way to ensure that the set function limit is σ-additive.

Authors: Tuğ Aida , Hodžić Mirzeta Memišević , Ballian Dalibor
Published: March 2022

Sweet chestnut forests in Bosnia and Herzegovina are underrepresented in the total forest fund, and their area is declining today. The research aims to determine the correlation relations of morphological traits of chestnut leaves, fruit and cupule in the population of Bosnian Krajina (northwestern Bosnia and Herzegovina) to undertake selection and breeding activities. Eleven traits of fruits, leaves and cupules were measured, seven assessed and six calculated. A mutual correlation for the researched traits was calculated using the Pearson correlation coefficient r. When the fruit traits and cupule traits were compared, the needle length showed a statistically significant correlation with most of the fruit traits. The traits of the number of fruits in the cupule and needle length had a statistically significant correlation coefficient with leaf blade width and leaf petiole length. The correlated traits can be distinguished as important for further selection and breeding of sweet chestnuts. The research results indicate that the genetic material of sweet chestnut is a rich source of genetic diversity and can be used in selection to obtain new varieties and cultivars in Bosnia and Herzegovina and for the protection of the indigenous gene pool.

Published: March 2022

The main goal of this study was to identify the unique gene pool of old and historically valuable Quercus robur L. and Tilia cordata L. to be able to characterise their genetic diversity in order to determine the polymorphism by expressed sequence tag-single sequence repeat (EST-SSR) markers and identify the most valuable specimens.

Morphological description, molecular genetic analysis, and statistical analysis were used in studies. The genetic distances between old-value trees of different Quercus L. and Tilia L. were determined based on EST-SSR markers and morphological characteristics.

Using polymerase chain reaction (PCR), alleles of the expected size were obtained. It was determined that four to eight alleles were obtained by seven SSR markers in the studied Q. robur L. samples. According to the calculated value of the locus polymorphism index (polymorphism information content [PIC]), the most polymorphic was the marker SSRQrZAG 65; the PIC was 0.84. The lowest value of PIC was observed in the marker SSRQrZAG 11; the PIC was 0.69. Intragenetic polymorphism was detected for all studied markers. Among the studied samples of linden, two to five alleles were identified. It was found that the highest value of PIC was obtained for the marker Ts920 – 0.72. The least polymorphic was the marker Ts927 (PIC was 0.28), which is not only due to the small number of alleles, but also their uneven distribution in the sample. Intragenetic polymorphism was detected in four of the six markers analysed for T. cordata L.

In this study, polymorphism was detected in all studied samples of Q. robur L. and T. cordata L., which allows to assess their genetic diversity based on the distribution of alleles.

Published: March 2022

Stability and performance are crucial characteristics for aerospace vehicles. The ability to investigate the aerodynamics and performance of rockets gives an insight into their stability before flight and the potential for design and performance enhancements. For the past 13 years, the rocketry Division within the students’ space Association of Warsaw University of technology has been developing sounding rockets of different designs and mission profiles. Two rockets have been chosen for the CFD (Computational Fluid Dynamics) campaigns, FOK and Twardowsky. This paper describes the mathematical model of aerodynamic loads used by the Division for sounding rocket simulation, followed by CFD campaigns for the two rockets. The results of the CFD analysis are then used to calculate the rockets’ aerodynamic derivatives according to a previously defined mathematical model.

Published: March 2022

High-frequency electromagnetic fields (EMF) can have a negative effect on both the human body and electronic devices. Monitoring and measurement of the electromagnetic field generated by devices is important from the point of view of environmental protection, the human body and electromagnetic compatibility. In this study, we tested the value of the electromagnetic field strength determined by the NHT3DL by Microrad with measurement probes during flights in the Robinson R44 helicopter. The reference point for the results obtained were the normative limits of the electromagnetic field permitted to affect the crew and passengers during flight. The maximum RMS values recorded during the measurements were E = 4.399 V/m in the 100 kHz–6.5 GHz frequency band and for the magnetic component H = 2.829 A/m in the 300 kHz–30 MHz frequency band.

Climate change is a global challenge that threatens the world today. Efforts to deal with the problem of climate change are inseparable from the extent to which individuals understand the issue of climate change. The purpose of this study was to determine the understanding of pre-service science teachers at Sriwijaya University on the issue of climate change. Data obtained through questionnaires and interviews. Data were analyzed qualitatively. The subjects of this study were 24 final semester students consisting of Physics Education, Biology Education and Chemistry Education study programs. The results showed that 1) pre-service science teachers (students) still did not explore and understand the issue of climate change where 75% of the responses of pre-service teacher students thought it was important to find solutions and understandings to overcome climate change; 2) students assume that climate change is a simple problem, this is shown from student response data, namely 59% know that increasing greenhouse gases can cause climate change. In addition, the difficulties that students experience in reducing the impact of climate change stem from behaviors that are often carried out by students in daily life such as being difficult to save electrical energy, difficult to dispose of waste according to its type. Students' understanding of climate change issues is still lacking and there needs to be awareness within each of them in order to encourage them to take climate change mitigation actions

The article highlights the prospects of using a new type of cream-dressing based on chlorella mi-croalgae. Due to changes in human life conditions, namely, a decrease in his physical activity, there is a need for a balanced diet containing the components necessary for a person. One of the sources of useful substances is algae. Due to the geographical location in the Russian Federation, the use of algae is not included in the historical food culture of the country's population. The im-portance of algae is underestimated. Cream-dressing based on chlorella algae, developed for the consumer who is accustomed to other components of nutrition perfectly combines national char-acteristics and beneficial properties of microalgae. The article reflects the beneficial properties of cream-dressing for humans and its effect on the body.

In this article, the growth, development and yield of peanuts (Arachis hipogaea L.) of the variety "Otradokubansky" in the conditions of the CDR are studied. As a result of the conducted research, it was found that peanuts are an ecologically plastic culture and easily adapts to the climatic fac-tors of the Central Asian Region. According to the results of phenological observations, deviations in the interphase period from sowing to emergence were revealed. The period of germination – budding and budding – flowering correspond to the development of culture in other regions. The entire growing season from sowing seeds to harvesting was 143 days. The use of two leafy top dressing Lebozol – and Revitaplant Legumes + NMgS and combinations of these fertilizers during the growing season is positive effect on the elements of the yield structure. The maximum yield according to the variants was 92g/m2.
Growth Functions, Rates and Classes of String-Based Multiway Systems

Inspired by the recently emerging Wolfram Physics Project where “Multiway Systems,” graph representations of abstract rewriting systems equipped with a causal structure, have played an important role in discrete models of spacetime and quantum mechanics, this paper establishes several more fundamental properties about the growth (number of states over steps in a system’s evolution) of string rewriting systems in general. While proving the undecidability of exactly determining a system’s growth function, we show several asymptotic properties all growth functions of arbitrary string rewriting systems share. Through an explicit construction, it is proven that string rewriting systems, while never exceeding exponential functions in their growth, are capable of growing arbitrarily slowly, that is, slower than the asymptotic inverse of every Turing-computable function. Additionally, an elementary classification scheme partitioning the set of string rewriting systems into finitely many nontrivial subsets is provided. By introducing arithmetic-like operations under which Multiway Systems form a weakened semiring structure, it is furthermore demonstrated that their growth functions, while always being primitively recursive, can approximate many well-known elementary functions classically used in calculus, which underlines the complexity and computational diversity of Multiway Systems. In the context of the Wolfram Physics Project, some implications of these findings are discussed as well.

Leptospirosis is a zoonotic disease in sub-tropical and tropical climates, could develop into epidemics in both rural and urban areas. Leptospirosis usually occurs after the patient comes into after contact with flood. In the last 5 years the case of disease has increased in DKI Jakarta, as well as in the Kebagusan sub-district of South Jakarta which consists of 8 RWs, from 2017-2019 there were found 5 cases and  potential for an epidemic at surrounding of neighborhood. Therefore, community engagement has a vital role to improve a disease prevention needs,  thus those  community are able to do an independently prevention activity or groups in their habitant. The activity begins with conducting an environment observational, advocacy and coordination, education and training for cadres, public facilities and infrastructure handling workers (PPSU) and residents representative of 3 RWs. From education results activities carried out on 36 targets, the pre-posttest on educated intervention was significant (p=0.000, T-paired test). It’s mean that the target increase their knowledge and understands the potential and risk of leptospirosis disease carried by rats for individual health and community after interventions. Empowerment can be started from the family level to maintain the cleanliness of the home environment as a form of personal responsibility and an important key to break the chain of leptospirosis transmission caused by rats

Sukosari Village is one of the villages in Kasembon District which has great potential in agriculture. In Sukosari Village, there is a Kelompok Wanita Tani (KWT) called KWT “Sri Tanjung” which has been producing food processing and agricultural handicrafts. Processed food products that have been produced and marketed are corn, cassava, and gadung chips, and packaged drinks called "Jaselang". These products have been packaged in good packaging and following the packaging requirements of food products. However, due to a large number of competitors with attractive packaging, this KWT member felt that packaging was one of the important things in attracting buyers. Another problem faced by partners is that so far they have done the packaging manually, there is no packaging machine used to package the food products produced. Thus, the purpose of Doktor Mengabdi program is to transfer knowledge related to packaging technology and provide assistance in the product packaging process. The method used in this activity is counseling and assistance related to food product packaging technology. Also, because in this activity two packaging machines were donated, namely an automatic bottle closing machine and a horizontal band sealer machine, the practice of using both machines was carried out. The results of this activity show that the empowerment activities are going well, KWT members have good knowledge of packaging technology. In addition, the existence of two packaging machines that were donated further increased their productivity.

The Zaaiplaats tin field is host to two of the historically most significant tin mines in South Africa. The geological maps of Zaaiplaats and Groenfontein have not been updated since the 1980s and 1950s respectively and warrant a renewed investigation. Cassiterite is hosted in the Bobbejaankop and Lease granites, of the Zaaiplaats and Groenfontein tin mines, which are part of the Lebowa Granite Suite of the Bushveld Complex. Tin mineralisation is primarily hosted as low-grade disseminations and within networks of high-grade hydrothermal pipes and lenticular ore-bodies. One difficulty in mapping such formations arises from the limited lithological variability between mineralised and unmineralised granitic facies. In order to map the granitic lithologies and discriminate alteration zones, an integrated approach is applied by combining remote sensing and in situ portable X-ray fluorescence (pXRF) mapping. The pXRF large ion lithophile (LIL) element distribution mapping, specifically correlating Rb, Sr and Ba with Sn, points to the concentration of late-stage magmatic-hydrothermal fluids, which are associated with endogranitic mineralisation. The use of the Rb/Ba ratio highlights regions of late-stage magmatic-hydrothermal alteration, effectively delineates granitic facies and identifies zones of potential tin mineralisation. Spectral image processing techniques were used as tools to support the mapping of these granites, their variable degrees of magmatic-hydrothermal alteration and regions of endogranitic disseminated mineralisation. We thus exemplify that an expert-based and synergic approach, combining inexpensive in situ pXRF and freely available satellite remote sensing data, supports the mapping and identification of endogranitic mineralisation in early exploration stages. Furthermore, due to its versatility, this approach can easily be applied to other styles of plutonic mineralisation.
