Authors: Fauzi Novi Irwan , Ulfah Maria , Yunis Yosi Fetria
Published: September 2021

Obesitas merupakan penimbunan lemak berlebih dalam tubuh yang disebabkan oleh lebih besarnya jumlah asupan makanan dibandingkan dengan yang digunakan oleh tubuh. Bawang dayak (Eleutherine bulbosa (Mill.) Urb) merupakan tanaman khas Kalimantan yang sering digunakan sebagai obat. Bawang dayak mempunyai metabolit sekunder seperti fenolik, flavonoid, alkaloid, tanin, saponin yang salah satunya bermanfaat sebagai antiobesitas. Penelitian ini bertujuan untuk mengetahui ada atau tidaknya efek antiobesitas ekstrak etanol bawang dayak pada tikus model obesitas. Tikus Wistar jantan dibagi menjadi 6 kelompok, masing-masing kelompok terdiri dari 5 ekor, yaitu kelompok kontrol normal, kontrol tikus obesitas, kontrol obat (orlistat 120 mg/kgbb), dan tiga kelompok uji ekstrak etanol bawang dayak dosis 100, 250, dan 500 mg/kgbb. Induksi obesitas dilakukan melalui pemberian pakan lemak tinggi selama 7 minggu pada semua kelompok kecuali kontrol normal. Terjadinya kondisi obesitas pada hewan uji dinilai dari nilai Indeks Lee â‰¥ 3. Uji efek antiobesitas dilakukan selama 21 hari pada tikus model obesitas. Efek antiobesitas dinilai dari indeks Lee dan persentase penurunan berat badan. Hasil pengujian menunjukkan ekstrak etanol bawang dayak pada dosis 100, 250, dan 500 mg/kgbb memiliki efek antiobesitas dengan persentase penurunan berat badan pada masing-masing dosis berturut-turut adalah 5,70%, 7,79%, dan 12,53%. Pemberian bawang dayak dosis 500 mg/kgbb selama 3 minggu pada tikus model obesitas dapat mengembalikan kondisi berat badan normal tikus dengan nilai penurunan nilai indeks Lee dari 0,31 menjadi 0,28.

Tahmin edilemeyen bir şekilde ortaya çıkan ve kısa sürede etkisini geniş çapta gösteren Covid-19 pandemisi birçok sektörde olduğu gibi spor endüstrisinde de krize neden olmuştur. Dünya genelinde uygulanan sokağa çıkma kısıtlamalarıyla birlikte spor müsabakaları durma noktasına gelmiştir. Spor müsabakaları normalleşme süreciyle birlikte yeniden başlasa dahi stadyumlara seyirci alınmasına izin verilmemiştir. Bu nedenle spor organizasyonları ne zaman tam anlamıyla sonlanacağı henüz belli olmayan pandemi süreci boyunca kitlelere ulaşmak için farklı yollar aramışlardır. Fiziki olarak kitlelerine ulaşma fırsatı yakalayamayan spor organizasyonlarının son yıllarda giderek gelişen espor olgusunu çalışmalarına adapte ettikleri görülmektedir. Spor organizasyonlarının Covid-19 salgını sürecinde yaşanan kriz döneminde esporu nasıl kullandıklarını ve kriz yönetiminin bir parçası olarak nasıl ele aldıklarını ortaya koymaktır. Sonuç olarak espor etkinliklerinin, spor organizasyonlarına kitlelere ulaşabilme ve onlarla ilişkilerini canlı tutabilme adına farklı bir içerik oluşturma imkânı sağladığı görülmüştür.
Ab-initio study of paramagnetic defects in Mn and Cr doped transparent polycrystalline Al2O3 ceramics

Published: September 2021

Birefringence is a major source of difficulty in sintering of transparent polycrystalline alumina ceramics, especially as the grain size exceeds a few hundred nanometers, which ultimately leads to complete opacity, mainly due to scattering of light. Recent studies have made it clear that by application of a strong magnetic field, alumina grains can be aligned along a particular crystallographic orientation, which minimizes scattering due to birefringence, and enhances transparency. Defects that cause spin delocalization are known to induce a paramagnetic behavior in alumina ceramics. Therefore, such defects have become a focal point of research for magnetic field assisted sintering of transparent polycrystalline alumina, in order to reduce the necessary magnetic field strength during production process. In light of recent studies on paramagnetic potentials of transition metal doped alumina, we have applied Spin Polarized Density Functional Theory (SP-DFT) calculations on manganese and chromium doped and co-doped alumina to calculate the magnetic moments, density of states and defect formation energies, which should be expected from this system of dopants, along with their interactions with oxygen vacancies. The results clearly indicate that formation of a point defect comprised of chromium and manganese positioned substitutionally at adjacent aluminum sites, in vicinity of an oxygen vacancy can induce a magnetic moment equivalent to 5 Bohr magnetons (μβ), outperforming previously reported defects. Based on this study we find it likely that chromium and manganese co-doping in alumina can further reduce the required magnetic field strength for production of transparent polycrystalline alumina.
INVESTIGATING THE IMPACT OF AN EXTERNAL INFLUENCE ON THE DYNAMIC BEHAVIOR OF DISLOCATIONS IN SILICON CRYSTALS
Authors: Drmeyan H.R. , Mirzoyan V.Gh.
Published: September 2021

The results of studying of the influence of a constant magnetic field on the dynamic behavior of dislocations in the crystalline block of an interferometer subsequently subjected to uniaxial mechanical tensile stress along the crystallographic axis of silicon are presented. The periodicity of the dilatation moire image after these influences, the average means free path of a dislocation in a crystal (block), the amount of slip, the average density of dislocations along the slip line, the relative deformation, and Young's modulus are calculated. To study the effect of a stable magnetic field on the dynamic behavior of dislocations in silicon crystals, a special three-block X-ray interferometer was fabricated in one of the blocks, and dislocations were introduced using the technique proposed by us. The experiments were carried out for various values of the magnetic field induction and mechanical stress. It is shown that the sequential action of these external influences leads to an increase in the starting stress, a decrease in the velocity of dislocation movement, a delay in the onset of dislocation movement, and the appearance of a hardening phenomenon. Experiments show that the displacement mobility characteristics are especially sensitive when the modulus of the magnetic induction vector reaches a certain threshold value for a given sample. It was shown that, in a sample containing silicon dislocations, the magnetic memory that appears after storage in a magnetic field is short-lived. It is found that the speed of movement of a dislocation in a magnetic field processed by a magnetic field, "then" subjected to mechanical stress (stretching), changes, but in practice the energy of its activation does not change. A theoretical analysis of the above experimental results is carried out, their scientific substantiation is given, all the factors associated with the phenomena observed in experiments are revealed.
Por que é preciso aprofundar o conceito de gêneros do discurso?
Authors: Lopes Bortolini Fernanda , Da Silva Valério Patrícia
Published: September 2021

Este artigo assume como objetivo revisitar o conceito de gênero do discurso, sob a perspectiva do Círculo de Bakhtin, para, por meio dessa incursão teórica, aprofundar o conceito de gênero em um conjunto de textos, para além do manuscrito clássico que o popularizou. Tem como corpus teórico os escritos de Bakhtin (1924), (2010[1975]), (2016 [1952-1953]); Medviédev (2016[1928]); Volóchinov (2017[1929]). O estudo revela que o conceito de gênero do discurso para Bakhtin e o Círculo assume a estrutura triádica – conteúdo temático, construção composicional e estilo, como parte essencial do conceito, mas outros elementos devem ser levados em consideração, como o contexto de produção do gênero, a esfera de atividade humana em que está ancorado o discurso que se materializa nos gêneros, os sujeitos envolvidos na interação, o auditório social, as relações dialógicas constitutivas do enunciado.
Os gêneros textuais especializados e o conceito de comunidade discursiva como elementos de análise da variação denominativa em terminologia
Authors: Serra Luís Henrique , Filho Francisco Alves
Published: September 2021

O texto apresenta um conjunto de reflexões acerca da relação entre a Terminologia e outros campos da Linguística e como essa relação pode colaborar para a ampliação da disciplina. São campos que colaboram na discussão a Linguística Textual e as Teorias dos Gêneros e do texto. No último campo, em especial, seria interessante um diálogo com os trabalhos de John Swales sobre a noção de comunidade discursiva. Parte-se do pressuposto que a análise de fenômenos estudados pela Terminologia pode ser feita a partir do diálogo da Terminologia com esses campos de conhecimento. As reflexões aqui apresentadas são feitas a partir da análise de um corpus diversificado com características que estão condicionadas à forma de comunicação dos especialistas de uma comunidade de especialista no setor da cana-de-açúcar. Os resultados mostram que muitos aspectos da variação terminológica podem ser entendidos a partir do tratamento de dados com reflexões teóricas do texto e do discurso presentes na Linguística.

Kurumsal muhafaza üzerine yapılan çalışmalar, kavramsal bir çerçeve olarak kurallar ve normlar ile kurumsal ilişkiler ve pratikler arasında genel bir uyum ve bu uyum sayesinde tutarlı bir işleyiş olduğunu göstermektedir. Fakat geçmiş çalışmalar, bu uyumun olmadığı durumlarda kurumsal muhafazanın nasıl gerçekleştiği sorusunu ihmal etmektedir. Bu çalışma, Soma Maden Faciası bağlamında, güvenlik kurallarının yaşamsal olduğu çok tehlikeli bir sektörde, güvenliği neredeyse yok sayan ve ilgili kurallarla çelişen üretim odaklı dar bakışın ve kurumsal işleyişin nasıl olup da bu kurallara dayanarak muhafaza edilip sürdürülebildiği sorusuna cevap arayarak literatürdeki bu açığı gidermeye çalışmaktadır. Çalışma, madenlerde güvenlik kurallarının üretimi sınırlamamak koşuluyla, keyfi, daha fazla güvenlik yönünde değişikliklere yol açmayacak şekilde, yeterince denetlenmeden ve madencilere ilgili eğitim verilmeden uygulandığına işaret etmektedir. Bu uygulama amirler ve madenciler arasındaki ilişkide üretim odaklı işleyişi besler ve amir-madenci ilişkisini üretim odaklı işleyişin sürmesini sağlayan bir kurumsal muhafaza işine dönüştürür.

Research is underway to develop a range of methods for assessing and managing exploration risk, progress, and value. As part of the research, a collaborative project was undertaken by SRK Consulting, working with Placer Granny Smith (the operating company of the Granny Smith Joint Venture owned by Placer Dome Asia Pacific, 60%, and Delta Gold, 40%) and Placer Dome Asia Pacific, to review and quantify exploration success in a mature program that has delivered several mines. In particular, an objective was to develop a measurement technique that is more commercially robust and informative than the traditional “cost per resource ounce discovered” method.

The project reviewed gold exploration over the past 13 years in the Laverton district of Western Australia. Placer Granny Smith has spent AUD$52 million (about US$30 million at recent exchange rates) defining 12 deposits with combined resources of more than 10 Moz (310 tonnes) of gold. Exploration centered on the Archean Granny Smith gold deposit, and was primarily targeted at outlining additional resources to feed through the Granny Smith mill. At an overall cost per resource ounce of less than US$3, this has clearly been a successful program. However, our analysis demonstrates that this figure fails to provide a complete value picture, and that the program could have delivered even greater value to the participating companies.

While the quantitative results of the review are specific to the Laverton district, the methodology can be applied to near-mine, advanced, and grassroots exploration programs for any deposit style in any geologic environment. Key outcomes of the review are as follows: Measuring exploration success in terms of the net present value of the deposit outlined produces a markedly different and arguably more commercially realistic outcome than measuring it in relation to the average cost of resources defined.Early recognition and prompt drill testing of key targets is critical in optimizing opportunities and realizing exploration value. Indeed, the principal destroyer of value in exploration is spending too much time and money prior to drill testing the best targets in any area.Continual and robust ranking of exploration targets should be undertaken. Exploration should aim to rapidly identify and systematically test the best exploration targets, rather than systematically exploring the project areas.

Especially in the current climate of a depressed resources sector, the exploration industry needs to compete aggressively for the investor’s dollar. The industry needs more robust and quantitative methodologies for measuring exploration effectiveness, and for informing management, investors, and shareholders of exploration risk, reward, value, and progress to discovery. The probabilistic methods described below provide such a framework.
Is the Redox state of the Archean Atmosphere Constrained?
Authors: Phillips G. Neil , Law Jonathan D.M. , Myers Russell E.
Published: September 2021

The nature of the Archean atmosphere has significant ramifications for ore-forming processes, and it is widely held that it was more reducing than at present. The case for a more reducing atmosphere (i.e., without ferric iron) during part of the Archean relies on evidence from inferred detrital uraninite and pyrite, the lesser volume of redbeds before 2 Ga, and possible altered paleosols. In favor of an oxidizing atmosphere similar to Present and with stable ferric iron are the inferred pisolites on unconformity surfaces in the Witwatersrand basin, some redbeds older than 2 Ga, and several Archean sulfate-bearing assemblages. Carbon and sulfur isotopes might favor an oxidizing atmosphere, as might the positive correlation between carbon and clay in clastic sediments, but much other evidence is either poorly supported, or nondiagnostic of atmosphere conditions. Inferred detrital pyrite, uraninite, and gold, and inferred paleosols also appear to be nondiagnostic, given the evidence for widespread alteration.
SEG Presidential Address: I Never Met a Rhyolite I Didn’t Like – Some of the Geology in Economic Geology
Authors: Price Jonathan G.
Published: September 2021

Rhyolites and their deep-seated chemical equivalents, granites, are some of the most interesting rocks. They provide good examples of why it is important to look carefully at fresh rocks in terms of fıeld relationships, mineralogy, petrography, petrology, geochemistry, and alteration processes. Because of their evolved geochemisty, they commonly are important in terms of ore-forming processes. They are almost certainly the source of metal in many beryllium and lithium deposits and the source of heat for many other hydrothermal systems. From other perspectives, rhyolitic volcanic eruptions have the capacity of destroying civilizations, and their geochemistry (e.g., high contents of radioactive elements) is relevant to public policy decision-making.
Remote Sensing in Mineral Exploration
Authors: Bedell Richard
Published: September 2021

The proliferation of remote sensing platforms has resulted in unprecedented opportunities for ore deposit vectoring. Importantly, remote sensing technology is now beyond the vague identifıcation of alteration, and can accurately map specifıc minerals and directly contribute to the understanding of ore systems. Remote sensing is making discoveries of new alteration zones within classic and previously well mapped ore systems, as well as outlining their geometry and mineralogy. Confıning this review to the geologically important reflected-light remote sensing systems, there are four main categories of sensors readily available to economic geologists, including the following: (1) submeter resolution panchromatic satellites that offer little spectral information but provide base maps; (2) multispectral Landsat satellites that can map iron and clay alteration; (3) the new ASTER satellite that can map important alteration groups and some specifıc minerals; and (4) hyperspectral airborne scanners that can provide maps of specifıc mineral species important to detailed alteration mapping.

At the core of comprehending this plethora of technology is the difference between spectral and spatial resolution. This review will provide an understanding of the more fundamental aspects of remote sensing systems that will help fıeld geologists to interact better with and leverage this rapidly evolving technology.

The correlations of reduced glutathione (GSH) and glutathione peroxidase (GPx) levels with biochemical markers of liver and kidney damage in Trypanosoma brucei brucei infection were studied in rats. Forty adult male rats divided into 2 groups of control and infected were used. Infected rats were inoculated intraperitoneally with 1.0 ml of blood at concentration of 1 x 106 trypanosomes per ml. Serum and tissue samples were collected on days 0, 3, 5 and 7 post-infection (pi) for biochemical analyses. Serum GPx activity had a significant (p < 0.05) positive correlations with liver (r = 0.96) and kidney GSH (r = 0.93) levels. All the measured serum parameters had significant (p < 0.05) negative correlations with serum GPx activity. In conclusion infection of rats with T. brucei brucei caused a decrease in the serum GPx activities and organ GSH levels with increasing parasitaemia and duration of the infection.

Published: September 2021

Body and craniofacial measurements are essential tools in identifying species and characterising their external traits. Body surface measurements were obtained from six African pangolins (Manistricuspis) – 3 males and 3 females. Facial and body measurements obtained from the pangolins revealed that the females had higher averages for body weight, body length and girth. The dimensions of the head showed that the males had a wider zygoma. Also, the manus and arm (humerus) in the females were longer (27.52±3.80 mm and 59.69±3.54 mm respectively) than in the males (26.95±3.35 mm and 50.68±10.22 mm respectively), while the lengths of the arm and the leg (all its components) were longer in the males. Data obtained from this study may provide basic information in assessing and comparing other species of the pangolin, and find application in archaeological, forensic and comparative anatomy of wildlife.

Three developmental abnormalities were found out of a total sample of eight hundred and twenty two within the genus Culicoides. These are two rare cases of double abdomen in females of the Schultzei and Imicola groups and a polar gynandromorphism, all in the genus Culicoides (biting midges) from Makurdi, Benue State, Nigeria. These females show double symmetrical abdomens equally attached to the meta-thorax and are related both on dorsal and ventral relative positions as well as larger and smaller relative capacities. The bi-abdomens in the Culicoides oxystoma (Schultzei group) were also separated by a speculated third rudimentary abdomen similarly attached to the meta-thorax; both abdomens possess three spermathecae (receptacula seminis) each but two spermathecae in the Culicoides imicola (Imicola group). The dorsal abdomen possesses eleven spiracles while the ventral sac, ten in the Culicoides oxystoma and revealed evidence of functionality; the dorsal abdomen was observed filled while the ventral only shows a smaller content volume. Both bi-abdominal specimens demonstrated no other apparent morphological dysfunction of other parts. On the other hand, the polar gynandromorphic specimen on stereomicroscopy revealed a typical female anterior portion and a posterior portion characteristic of male adult Culicoides. Further examination of the specimen showed absence of spermatheca. These abnormalities are the first reports of any type in invertebrates in Nigeria.

This study was carried out to document the pelvic and testicular biometric characteristics of Sahel goats. Record of body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference were obtained from 400 male and 600 female Sahel goats. All the goats were approximately 1.5 years old and weighing 14 to 18 kg, with body condition score of 3 or 4 (scale of 1-5). The mean bodyweight of Sahel bucks was 15.12 ± 1.10 kg while that of Sahel does was 13.22 ± 1.12 kg, height at withers in bucks and does were 52.22 ± 1.20 cm, and 48.13 ± 1.23 cm respectively. The scrotal length and circumference in Sahel bucks were 11.39 ± 1.12 cm and 17.95 ± 1.21 cm respectively. The external pelvic circumference in Sahel does was 55.13 ± 1.16 cm. There was significant (P<0.05) positive correlation between the body weight and body condition score in bucks (r=0.52) and in does (r=0.42). It was observed that there was weak but positive correlation between the body weight and height at withers (r=0.34), in bucks and in does (r=0.25; P <0.5). A low but significant positive correlation was found between the body weight and scrotal circumference r=0.28, (P<0.05) in bucks. There was a highsignificant positive correlation between the scrotal length and scrotal circumference r=0.66, (P <0.05).  The external pelvic circumference in Sahel does was also significantly positively correlated with body weight r=0.40, (P<0.05) and with the body condition score r= 0.33, (P<0.05). In conclusion, the body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference of Sahel goats in Maiduguri were successfully determined, these parameters studied might serve as a bases for determining the breeding soundness of Sahel goats.
