Authors: Albino Izabela , Conde Erick
Published: July 2019

Estresse e ansiedade são variáveis que podem influenciar no desempenho dos jogadores de futebol. Estudos recentes têm demonstrado que condições específicas dos quais os atletas são submetidos no ambiente esportivo podem aumentar a prevalência de determinados transtornos mentais. Pensando nisso, foi realizada uma revisão sistemática com o intuito de verificar estudos que estão investigando essa associação entre estresse e ansiedade nos atletas de futebol profissional, verificando assim os instrumentos utilizados para mensuração dos mesmos. Foram realizadas consultas nas bases indexadoras entre o segundo semestre 2017  e primeiro semestre de 2018 nas bases de dados Pubmed (US National Library of Medicine) e Web Of Science. Para realização da pesquisa foi utilizado os descritores  ("stress” OR “anxiety") AND (“soccer” OR “football” AND “professional”) . Após aplicação dos critérios de inclusão e exclusão, foram analisados 33 estudos. O estudo possibilitou compreender que a maioria dos instrumentos encontrados utilizaram indicadores fisiológicos para mensuração do estresse, portanto se tratando de indicadores no aspecto psicológico não foram encontrados muitos instrumentos, possibilitando assim compreender que nos estudos atuais há uma preferência por indicadores fisiológicos no que  diz respeito aos protocolos e instrumentos utilizados para medir o estresse e ansiedade nos jogadores de futebol.

Authors: Pires Bruna Soares , Carvalho Cristianne Almeida
Published: July 2019

Em um cenário de adaptação global à modernidade (final do séc. XIX e início do século XX) e busca de uma identidade nacional, chega ao Brasil o futebol, incentivando a adesão de homens – mas de mulheres também. É sobre a participação feminina no futebol brasileiro, em especial na capital maranhense, que este artigo versa, cujos resultados apontam que apesar do preconceito ainda presente e falta de reconhecimento às mulheres jogadoras de futebol, elas são “craques da resistência” diante dos obstáculos e se movem a partir de ideais pessoais e coletivos. Espera-se que este artigo possa ilustrar a realidade maranhense e favorecer reflexões importantes sobre o futebol feminino, assim como favoreça mais estudos na área.

Published: July 2019

Makalah ini menyajikan suatu performa metode aliran daya fast decoupled di jaringan distribusi. Karakteristik jaringan distribusi diantaranya rasio saluran R/X tinggi, struktur radial, saluran terdiri dari 1, 2, dan 3 fasa, serta beban tidak seimbang. Permasalahan mengenai kompleksnya karakteristik jaringan tersebut menuntut para peneliti untuk mengembangkan metode aliran daya konvensional agar dapat diterapkan. Metode aliran daya fast decoupled dapat bekerja dengan baik di jaringan transmisi. Karakteristik jaringan distribusi dengan rasio saluran R/X yang tinggi mengurangi kemampuan konvergensinya dan bahkan terjadi divergensi. Oleh karena itu, makalah ini mengajukan pengembangan metode fast decoupled berupa rotasi sumbu yang dilakukan di setiap bus. Pengujian dilakukan pada standar jaringan distribusi IEEE 13 dan 34 bus. Performa pada jaringan distribusi 13 bus membutuhkan 3,5 iterasi dengan waktu komputasi 0,049 detik dan sudut rotasi optimal -43,4°, sedangkan performa pada jaringan distribusi 34 bus membutuhkan 4 iterasi dengan waktu komputasi 0,152 detik dan sudut rotasi optimal -61,4°. Ketika dibandingkan dengan metode Backward-Forward Sweep (BFS) yang merupakan metode favorit dalam melakukan perhitungan aliran daya di jaringan distribusi radial, menunjukkan bahwa keduanya memiliki performa yang sama baiknya. Oleh karena itu, metode rotasi sumbu fast decoupled layak diterapkan dengan variasi karakteristik jaringan distribusi. Selain itu, metode ini dapat diterima secara umum karena tidak hanya dapat diterapkan dengan baik di jaringan transmisi, tetapi di jaringan distribusi.

Published: July 2019

Salah satu metode pembangkitan gelombang ultrasonik berbasis piezoelektrik adalah dengan memicu transduser oleh pulsa singkat dan tegangan tinggi. Pulsa ini dapat dibangkitkan dengan pensaklaran (switching) tegangan tinggi searah (DC) oleh pulsa penggerak (drive). Makalah ini menyajikan perancangan dan fabrikasi generator pulsa-singkat tegangan-tinggi repetitif terprogram dengan berbasis mikrokontroler ATMEGA 128. Pulsa dibangkitkan dari mikrokontroler ATMega sehingga interval dan skala repetisi dapat diatur melalui tombol input. Parameter-parameter pulsa tersebut ditampilkan pada peraga LCD (Liquid Crystal Display) untuk mempermudah pengguna dalam operasional generator. Pulsa dari mikrokontroler diubah menjadi lebar pulsa yang lebih singkat melalui sebuah multivibrator monostabil. Pulsa dari multivibrator selanjutnya diubah menjadi sinyal singkat level +15V sebagai input gerbang MOSFET untuk pensaklaran tegangan tinggi DC lalu dikonversi menjadi sinyal spike negatif. Hasil pengujian menunjukkan bahwa pulsa singkat repetitif terprogram dapat dibangkitkan untuk pensaklaran tegangan DC oleh MOSFET. Lebar pulsa sinyal spike negatif dibangkitkan hingga 100 ns. Sinyal ini mampu memicu transduser 1 MHz untuk pembangkitan gelombang ultrasonik. Berdasarkan pengujian, dapat disimpulkan bahwa generator dapat membangkitkan sinyal spike negatif dengan repetisi yang terprogram dan sesuai dengan frekuensi kerja transduser ultrasonik.

Compact Fluorescence Lamp Based on Power Electronics Technology: its Advantages and Disadvantages
Authors: Heryana Nana , Iskandar Handoko Rusiana , Widodo Bambang , Purba Robinson
Published: July 2019

Power-electronics based Compact Fluorescent Lamps (CFLs) have been proven to reduce electrical energy consumption for lighting purpose. As in common power-electronics-based electrical devices, CFLs can be categorized as non-linear loads. Therefore, the input current has a non-sinusoidal waveform and contains harmonics. This paper discusses the advantages and disadvantages of CFL application and proposes the attachment of THD value to the product package in order to improve the marketing policy. Total Harmonic Distortion (THD) is a method used to find the percentage value between the total harmonic components and their fundamental components. The percentage of THD causes the greater risk of damage to equipment due to harmonics that occur in current and voltage. Laboratory testing shows that a CFL sample has THD of the input current as high as 67.7%. This THD is relatively high and may degrade the electrical power quality. Moreover, it could lead to the misreading of electrical power and energy meter. Several experiment results are shown and analyzed to confirm the validity of the discussed matter.

More than Luck
Authors: Hightower Ben , East Scott
Published: July 2019

This introduction begins by challenging a common narrative formed in relation to Australia—that it is a “lucky country.” This “exceptionalist” view of Australia is also evidenced in national legal frameworks relating to human rights. Drawing on histories of Australian politics, it is argued that social justice stems not from luck or an exceptional legislative system, but from various forms of social contestation. Especially since the global protests of 2011, more scholars are considering the organization, impacts, and practices of social movements that occur on a global scale. Despite the evolution of globalized protest, this collection is informed by Connell’s southern theory (2007), which identifies the unequal geopolitics of knowledge. The articles in this issue provide a diverse range of case studies that can inform protest practices and evidence the vitality of dissent in Australia. Activist knowledges and a quest for collaborative approaches to protest are the two elements that run throughout this issue of Contention.
"Welcome to Country" and "Acknowledgment of Country"
Authors: Pelizzon Alessandro , Kennedy Jade
Published: July 2019

In the past two decades, “Welcome to Country” and “Acknowledgment of Country” practices have become commonplace at the commencement of most public events throughout Australia, and it is highly unusual to participate in a public event where some words of acknowledgment of the traditional owners and custodians of the locale are omitted. This article traces the origins of such practices while identifying the semantic, political, and conceptual differences between them. It articulates how precolonial protocols of encounter among distinct groups and individuals inform “Welcome to Country” practices, attesting to the ontological and epistemological continuity of the latter in relation to the former. It explores recent trends in the public understanding and positioning of both “Welcome to Country” and “Acknowledgment of Country” speeches and events, contextualizing their emerging positioning within the fabric of Australian settler colonial relations, particularly in the context of contemporary discourses on Aboriginal sovereignty and the constitutional recognition of Aboriginal and Torres Strait Islanders.
The Multiple Modes of Protesting Live Exports in Australia
Authors: Mummery Jane , Rodan Debbie
Published: July 2019

Signaling dissatisfaction with particular events, policies, or situations, modes of protest encompass individual expressions through to the development and mobilization of social movements. Indeed, protests can range from bodies blocking space and time to the aggregation of clicked signatures in an online petition and the sharing of campaign content through social media. All of these modes are currently employed within the Australian public sphere to bring about change or closure of the live export industry. This article analyzes the current dimensions and flows of public protest against Australia’s live export industry, examining how they are shaped not only by a myriad of organizations but also by differing modes of protest, as well as by the different modes of appeal in use by activists to mobilize the Australian public sphere in protest. Through this discussion, insight is gained into some of the capacities and efficacies of multimodal protest and its significance for both public engagement and political and industry uptake.

Published: July 2019

As a result of mineralogical and thermobarogeochemical researches of different-age basaltic complexes of Archipelago Franz Josef Land (FJL) regular changes in time of compositions of plagioclases, clinopyroxenes and melt inclusions are established. Chemical compositions of inclusions directly testify to prevalence in Early Jurassic of plateau basaltic melts similar (according to the content of the basic components, and also trace and rare-earth elements) to typical basalt tholeiitic magma of the Siberian platform. In Early Cretaceous melts already had the enriched subalkaline character. Calculations of conditions of magma generation, spent on the basis of the data on melt inclusions, have shown evolution from Early Jurassic to Early Cretaceous (with allocation of three peaks of magmatic activity: 192.2±2.8, 157.4±3.5 and 131.5±0.8 million years) depths and temperatures (accordingly: 70-110 km and to 120 km, 1430-1580°С; 60-110 km, 1390-1580°С; 50-140 km, 1350-1690°С) of mantle melting with formation of deep sources of the FJL magmas.

Authors: Nursidika Perdina , Mahargyani Wikan , Anggraeni Fitri Kurnia
Published: July 2019

Total cholesterol is the composition of many substances including cholesterol, triglycerides, LDL cholesterol, and HDL cholesterol. Cholesterol examination is one of the most frequent tests required in the laboratory to monitor vascular and cardiovascular diseases. Most clinical pathology laboratories use photometer to perform clinical chemistry checks. Cholesterol testing can also be done with Point of Care Testing (POCT) which has a working principle of biosensor technology. This research method is experimental, using 40 samples that can represent normal and pathological levels. All samples will be checked for total cholesterol with a photometer of CHOD-PAP method and 3 POCT Lipid Pro. The results showed linear regression y = 0.955x + 1.8325 with R2 of 0.9955. The linear regression value is calculated by Total Error (TE), while the Total Error Allowable (TEa) cholesterol is 10%. The bias value is 0.31%, TE for normal level = 5.92% and TE for high pathological level = 3.00%, it can be stated the result of examination can be compared or accepted. The% TE value obtained is less than the TEa value of cholesterol. It can be concluded that the total cholesterol results examined by the photometer and LipidPro are comparable. For further research it is advisable to use a total cholesterol sample that has a value of more than 400 mg/dL.

OBJECTIVE:

In order to verify the effect of short recovery periods (24-hours) in the subsequent match, the response of salivary cortisol (sC) and match intensity were investigated in two successive soccer matches during an official tournament.

METHODS:

Twenty (20) young soccer players (16.8 [Formula: see text] 0.5 years; 172.9 [Formula: see text] 7.7 cm; 65.0 [Formula: see text] 7.9 kg) accepted to participate and 14 completed the 2 matches within a two day-period. Subjects provided saliva samples before and after each match and the session rate of perceived exertion, (session-RPE) method was utilized to define the match intensity.

RESULTS:

The sC concentration significantly increased in both matches ([Formula: see text] 0.05), representing an increase of 74% and 112% in matches 1 and 2, respectively. Moreover, the variation was not different between the matches ([Formula: see text] 0.05). There was no variation in match internal load for match 1 to match 2 ([Formula: see text] 0.05). A significant difference was noted between high and low salivary cortisol groups divided a posteriori into both matches (match 1: [Formula: see text] 0.001; ES: 2.7 and match 2: [Formula: see text] 0.001; ES: 2.3).

CONCLUSIONS:

The findings of this study indicate that the short recovery-time did not influence the sC and match internal load responses in the subsequent match. In addition, athletes with high responsiveness to the stressful demands of the matches tend to maintain this condition regardless of the time on field and the RPE reported.

Published: July 2019

BACKGROUND:

Distal radius fractures are the third most common fracture observed in osteoporotic patients. In addition, wrist muscle weakness may be a risk factor for such fractures because of the protective role these muscles play during falls.

OBJECTIVE:

The main objective was to explore isokinetic wrist muscle strength in osteoporotic and matched non-osteoporotic postmenopausal women.

MATERIALS AND METHODS:

Twenty osteoporotic postmenopausal women (patient group) and 15 healthy non-osteoporotic postmenopausal women with a normal DXA score (control group) were recruited. Bone mineral density was measured using a DXA device. Vertebral (L1–L4), femoral neck, and femoral total measurements were recorded. Wrist muscle strength was evaluated isokinetically.

RESULTS:

Peak moment values of the wrist flexors at 60 and 180[Formula: see text]/s were significantly lower in the patient group than in the control group. Extensor muscle strength did not differ significantly between the 2 groups.

CONCLUSION:

Wrist flexors strength is lower in osteoporotic postmenopausal women than their non-osteoporotic counterparts. As this variation might be a risk factor for distal radius fractures in osteoporotic postmenopausal women, strengthening this muscle group should be seriously explored.

Published: July 2019

Relevance. A key role in the pathogenesis of the brain injury is played by destructive changes in the hypothalamus neuroendocrine cells. For the correction of such disorders, promising is carbacetam, which has antihypoxic, anti-edema and anti-shock effects. Objective: to investigate the effect of carbacetam on the processes of neurodegeneration in the paraventricular and supraoptical nuclei of the hypothalamus in the experimental brain injury. Material and methods. Brain injury were modeled on the V.M. Elskyy &S.V. Ziablitsev model on white non-breeding male rats weighing 200±10 g. Experimental animals (n=10) received intraabdominal injection of carbacetam at a dose of 5 mg/kg in 1 ml of physiological saline during the seven days after injury. In the control group (n=10), 1 ml of physiological saline was injected. Hypothalamic tissue microparticles performed a morphological and immunohistochemical evaluation of neurodegenerative changes when stained with hematoxylin and eosin and immunohistochemically to detect NSE, S-100 and GFAP neuromarkers. Results. Carbacetam reduced the degenerative processes in the nervous tissue of the paraventricular and supraoptical nuclei of the hypothalamus, which was manifested by the restoration of normal morphological features, in contrast to rats that did not receive the drug. Immunohistochemically, GFAP and S-100 glial markers exhibited reduced, reflecting a reduction in degenerative changes in the nerve tissue. Expressions of the neurons marker NSE increased, reflecting high metabolic activity of the neurons. Conclusions. Revealed changes in the expression of markers of neurons and glia showed a restoration of normal neuronal activity due to the introduction of carbacetam.

Published: July 2019

Introduction: Hemolysis, Elevated liver enzyme, low platelet (HELLP) syndrome is often noted as a complication of preeclampsia but can occur without this association as well. Severe form often requires termination of pregnancy. Vitamin B12 deficiency is common in vegetarian population and can mimic HELLP syndrome.

Case Summary: We present an interesting case which was initially thought to be HELLP syndrome based on the clinical presentation and patient was planned for induction of labour,  but later on it was found out to be a case of Vitamin B12 deficiency on the basis of Lab findings. Patient responded well to the B12 supplementation and unjustified termination of pregnancy was avoided.

Conclusion: This case illustrates an interesting clinical misdiagnosis of HELLP syndrome in an overt megaloblastic anemia. An elaborated workup with clinical suspicion should be made for megaloblastic anemia in such condition.

Published: July 2019

Background

Vitamin D deficiency is a global health problem, and its role as an immune modulator has been recently tightened. The main role of vitamin D is to maintain calcium and phosphorus homeostasis, thus maintaining bone health. Recent evidence has shown that vitamin D may play a role in a variety disorders such as endocrine diseases, adrenal diseases, polycystic ovary syndrome and particular type 1 diabetes, type 2 diabetes. We evaluated the association between thyroid disorders (subclinical or overt hypothyroidism and subclinical or overt hyperthyroidism) and serum vitamin D3 level in the Indian population and its association with ionized calcium.

Methods

The cross-sectional study, included patients who visited Shree Krishna Hospital, Karamsad for thyroid evaluation or follow-up. We conducted this study involving a total of 84 individuals with normal thyroid function, were recorded as control. The cases group included 75 patients with hypothyroidism (overt or subclinical) and 10 patients with hyperthyroidism (overt or subclinical). Serum levels of vitamin D3, thyroid function and calcium ionized were measured in all adult subjects. Deficiency of vitamin D is defined as the level of vitamin D3 in the serum less than 50 nmol/L. Vitamin D insufficiency is defined as serum vitamin D3 level between 50 - 75 nmol/L. Vitamin D sufficiency is defined as serum Vit D3 level >75 nmol/L.

Result

The prevalence of vitamin D deficiency in subclinical and clinical hypothyroidism cases (36 of 40, 90%) was significantly higher than that observed in healthy individuals (0 of 40, 0%). The prevalence of vitamin D deficiency in subclinical and clinical hyperthyroidism cases (4 of 40, 10%). The prevalence of vitamin D insufficiency in subclinical and clinical hypothyroidism cases (24 of 62, 38.7%) was significantly lower than that observed in healthy individuals (controls) (35 of 62, 56.5%).The prevalence of vitamin D insufficiency in subclinical and clinical hyperthyroidism cases (3 of 62, 4.8%).  The prevalence of vitamin D sufficiency in subclinical and clinical hypothyroidism cases (15 of 67, 22.4%) was significantly lower than that observed in healthy individuals (controls) (49 of 67, 73.1 %). The prevalence of vitamin D sufficiency in subclinical and clinical hyperthyroidism cases (3 of 67, 4.5%).

Conclusion

Vitamin D deficiency was associated with hypothyroidism especially clinical hypothyroidism. Low serum levels of vitamin D3 were associated with high serum TSH levels.

Introduction: Cardiovascular diseases are the most prevalent cause of mortality and morbidity in both developed as well as developing countries. Coronary artery disease (CAD) is usually due to atherosclerosis of large and medium sized arteries. Dyslipidemia and hyperglycemia have been found to be the important contributing factors.

Aims and objectives: Present study is done to know the pattern of dyslipidemia and blood glucose status as per National Cholesterol Education Program – Adult treatment panel III (NCEP-ATP III) guidelines and American Diabetes Association (ADA) criteria respectively in young doctors and to sensitize the importance of its implication and to take timely preventive measures.

Material and methods: This is a retrospective observational study conducted in a tertiary care hospital. The study group comprised of 173 young doctors from all over India, between age 25 to 29 years who reported to lab for routine medical investigations. The study group included 118 males and 55 females. Serum lipid profile and plasma glucose for 173 subjects were analyzed.

Results: In our study 71.7% of total study group had impaired range of plasma glucose values and 10.4% had diabetic range plasma glucose.5.78% of total subjects had Triglyceride (TG) level more than 200 mg/dL.11.56% had total cholesterol (TC) level >240 mg/dL. 45.66% of total subjects had Low density lipoprotein cholesterol (LDLc) more than 130 mg/dL. 37.2% of males had high density lipoprotein cholesterol (HDLc) less than 40 mg/dL. 40% of females had HDLc less than 50 mg/dL. Thereby implying that even apparently healthy young medical professionals are at increased risk of metabolic disorders like diabetes and dyslipidemia.

Conclusion: This study revealed higher prevalence of hyperglycemia and dyslipidemia in apparently healthy medical professionals suggesting higher risk for metabolic disorders like coronary artery disease and diabetes mellitus. The study indicates the need for physical exercise, change in dietary pattern and regular monitoring of biochemical indicators of metabolic diseases.
