HARMONIZING RELATIONSHIPS OF CENTRAL GOVERNMENT AND REGIONAL GOVERNMENTS IN SHARE DIVESTMENT OF MINING COMPANIES
Authors: Tiopan Demson 
Published: November 2020

Menurut Pasal 1 angka 8 Peraturan Pemerintah No. 23 Tahun 2010 tentang Pelaksanaan Kegiatan Usaha Pertambangan Mineral dan Batubara, divestasi saham adalah jumlah saham asing yang harus ditawarkan untuk dijual kepada peserta Indonesia.Upaya divestasi saham ini dilakukan sepenuhnya oleh pemeritah pusat tanpa melibatkan pemerintahan daerah yang menjadi daerah eksplorasi perusahaan tambang.Berlakunya sikap pemerintah pusat kepada pemerintah daerah yang tidak mencerminkan tujuan hukum dalam upaya divestasi saham perusahaan tambang . Penulisan Paper ini menggunakan metode penelitian hukum normatif yaitu dengan meneliti pada data sekunder bidang hukum yang ada sebagai data kepustakaan dengan menggunakan metode berpikir deduktif dan kriterium kebenaran koheren. Untuk menganalisisnya permasalah ini penulis menggunakan teori tujuan hukum dari Gustav Radbruc dikaitkan dengan sistem hukum yang dikemukakan oleh Lawrence Friedman. Penulis menemukan bahwa Norma hukum yang ada pada dasarnya tidak mengehendaki pembagian yang tidak adil akan tetapi di dalam norma-norma hukum yang lain terdapat ketentuan mengenai tindakan-tindakan khusus yang dapat dilakukan pemerintah pusat khususnya di dalam bidang pertambangan yang dapat dijadikan celah pemerintah pusat dalam memonopoli divestasi saham. Upaya hukum juga pada dasarnya mengupayakan sikap pemerintah pusat yang berimbang kepada pemeritnah daerah untuk memajukan masyarakat daerah.Penulis menyarankan bahwa legislatif harus membentuk undang-undang yang mengatur lebih detail mengenai divestasi saham yang dilakukan pemerintah pusat dimana juga megedepankan pemerintah daerah. Jika keuangan pemerintah daerah tidak mampu melakukan upaya divestasi saham perusahaan tambang seharunsya pemerintah wajib meberikan hibah divestasi sahamnya, walaupun pemerintah kehilangan sahamnya tetapi pada prinsipnya hibah tersebut digunakan untuk kemakmuran rakyat di daerah.

Published: November 2020

This paper reports an experimental comparative thermal analysis of a flat plate heat exchanger and corrugated plate heat exchanger (CPHE) of different corrugation angles using ethylene glycol as test fluid. The experiments were carried out counter current mode using water as hot fluid at 75°C. Design of each plate provided with eleven thermocouple sensors to determine the temperatures, in which seven were used to measure the surface temperature of plate and four were used to measure the inlet and outlet bulk temperature of cold and hot fluids. The mass flow rate of test fluid, varied between 0.5 to 4 liters per minute and corresponding steady state temperatures is measured. Using experimental readings, temperature difference between the inlet and outlet streams (DT), logarithmic mean temperature difference (LMTD) and overall heat transfer coefficient (U) are determined. The obtained DT and U values of corrugation angles (300, 500) of CPHE were compared with those of flat plate heat exchangers. For corrugation angle of 30° and 50°, the DT and U values increases with increase of mass flow rate of the fluid.

#naukanatwitterze. O multimodalnym designie informacji w dyskursie cyfrowym
Authors: Makowska Magdalena 
Published: November 2020

The subject of the article are the ways of popularizing scientific and popular science knowledge by using Twitter as a social media platform. The research corpus comprises 100 tweets which come from institutional and individual senders, including both representatives of the world of science as well as of the media that aim to popularize scientific knowledge. As a result of the medialinguistic analysis, which focused on the structural and functional plane of the studied media texts, the high representativeness of multimodal tweets was noted. Namely, language and image contextualize each other: the image allows us to fill the semantic gap resulting from the ellipticalness of the verbal layer of a given tweet. Thus, the contribution of the multimodal information design to knowledge transfer in digital discourse has been demonstrated.

Published: November 2020

BACKGROUND: There is insufficient data to recommend screening for bladder cancer (BC). For future BC screening trials, it is important to understand how and if tumor (T) stage can act as a surrogate outcome marker for overall (OS) and cancer-specific (CSS) survival. OBJECTIVE: To characterize OS and CSS between primary tumor (T) stages in non-metastatic bladder cancer (BC) patients. METHODS: Non-metastatic BC patients were identified in the National Cancer Database (NCDB; 2004-2015) (n = 343,163) and National Cancer Institute Surveillance, Epidemiology, and End Results database (SEER) (n = 130,751). Cox multivariable regression compared relationships between T stage (LGTa, HGTa, Tis, LGT1, HGT1, T2-T4) and OS or CSS for all patients and sub-cohorts. RESULTS: Compared to stage LGTa as a reference, overall (SEER; NCDB) and cancer-specific (SEER) survival significantly declined with increasing T stage. Using SEER, OS ranged from HGTa (HR 1.16, CI 1.13–1.21, p < 0.001) to T4 (HR 5.70, CI 5.41–6.00, p < 0.001) with a steep inflection between HGT1 (HR 1.68, CI 1.63–1.73, p < 0.001) and T2 (HR 3.39, CI 3.30–3.49, p < 0.001), which was verified with NCDB. The association of stage and CSS was even more pronounced: HGTa (84% 10 year-CSS, HR 1.94, CI 1.81–2.08, p < 0.001), Tis (82% 10 year-CSS, HR 2.28, CI 2.09–2.47, p < 0.001), LGT1 (84% 10 year-CSS, HR 2.30, CI 2.11–2.51, p < 0.001), HGT1 (72% 10 year-CSS, HR 4.24, CI 4.01–4.47, p < 0.001), T2 (48% 10 year-CSS, HR 12.18, CI 11.57–12.82, p < 0.001), T3 (45% 10 year-CSS, HR 14.60, CI 13.63–15.64, p < 0.001), and T4 (29% 10 year-CSS, HR 22.76, CI 21.19–24.44, p < 0.001). CONCLUSIONS: Earlier T stage at diagnosis was associated with better OS largely due to differences in CSS. A clinically significant difference between Stage I and Stage II was verified herein in multiple cohorts. Therefore, earlier stage at diagnosis, specifically preventing muscle invasive BC, could potentially improve survival.
Entrevista com o professor David Lambert

Published: November 2020

Esta entrevista foi realizada durante contextos políticos conturbados tanto na Inglaterra quanto no Brasil. Enquanto nos trópicos vivenciamos tempos-espaços de reformas e instabilidades político-econômicas, o Reino Unido experimenta a incerteza do futuro “Brexit”. A entrevista com Dr. David Lambert aconteceu no dia 18 de maio de 2017, na Universidade de Londres (Institute of Education, UCL). Os corredores das salas do Departamento de Currículo Pedagogia e Avaliação vêm testemunhando mudanças, proposições e alternativas, particularmente no âmbito do currículo, há mais de quatro décadas. Nesta entrevista, David Lambert nos apresenta a dinâmica curricular na Inglaterra e, em particular, defende “a virada do conhecimento”, como abordagem que resgata a potencialidade da organização curricular por disciplinas e o protagonismo do oficio docente, afastando-se assim de uma perspectiva conservadora, da educação tradicional. Para tanto, ele sustentou seu argumento a partir da categoria de “conhecimento poderoso” de Michael Young, em que se baseia na função epistemológica da escola e seus desdobramentos para a justiça social.
A construção do pensamento geográfico escolar no Brasil: uma análise a partir dos livros didáticos produzidos por professores do Colégio Pedro II
Authors: Silva Elaine Queiroz 
Published: November 2020

O Colégio Pedro II sustentou ao longo de sua história o caráter modelar, que de certa forma se mantem até a atualidade. Seu acervo, composto pelos mais diversos documentos, muito tem a auxiliar para a compreensão da constituição dos mais diversos campos disciplinares, inclusive da Geografia. No caso da Geografia, devemos nos recordar da importância do Colégio Pedro II para a sua institucionalização, tanto no âmbito da escola básica quanto da academia (ROCHA, 2009, 2014; SILVA, 2012). Desde a sua fundação, o seu quadro docente era formado por ilustres professores, intelectuais reconhecidos pelo “notório saber” selecionados na comunidade letrada do Império e que possuíam diversas formações e atuações, “membros de uma elite intelectual que buscou sua formação inicialmente no exterior e mais tarde no Brasil” (SANTOS, 2009, p. 71). Logo, não podemos diminuir a importância destes intelectuais e seu papel crucial para a história do pensamento geográfico escolar e universitário brasileiro. Estudos acerca destes professores, de suas trajetórias, e, principalmente, de sua produção didática, podem elucidar importantes informações sobre a situação escolar, a formação docente e o ensino de Geografia ao longo de sua história. Ressaltamos a importância da produção, pois consideramos o livro didático um objeto de “múltiplas facetas” (BITTENCOURT, 1993), sendo, sobretudo, um veículo de valores ideológicos e/ou culturais. Diante de tais fatores, analisaremos, neste artigo, algumas obras publicadas por autores que atuaram como professores do Colégio Pedro II durante o período que se estende do início da Primeira República ao fim do Estado Novo (1889-1945).

Authors: Hossain Nasrin , Khan Farhana Tarannum , Mahmud Mohammad Sharif 
Published: November 2020

Background: Ovarian cancer is the ninth most common cancer in women and it ranks fifth as the cause of cancer death in women. Epithelial ovarian cancer (EOC) represents the most lethal malignancy of the female genital tract. EOC is typically diagnosed in advanced FIGO (Federation of International Gynaecology and Obstetrics) stages due to lack of symptoms in the earlier stages. So, the aim of this study was to determine the disease free survival (DFS) of EOC after treatment and also to find out the prognostic factors such as age, FIGO stage, histopathological subtypes and grade for recurrence of disease.
Methods: A retrospective study was conducted in gynaecological oncology department of National Institute of Cancer Research and Hospital (NICRH), Dhaka. Study period was 02 years from January 2017 to December 2018.Histopathologically confirmed epithelial ovarian malignancy after completion of treatment was included in this study. Non-epithelial ovarian malignancy was excluded from this study.
Results: Mean age was 53 yrs (range 25-80 yrs).Final surgical staging (FIGO stage) of disease were as follows stage I; 24 (25.8%), stage II; 18 (19.4%), stage III; 45 (48.4%) and stage IV; 6 (6.5%). Mean follow-up time was 34 months (range 24-60 months). DFS according to FIGO stages were 35 months, 27 months, 25 months and 9 months respectively. DFS based on the complete and incomplete surgical staging were 27 months and 22 months respectively. At univariate analysis, factors significantly associated with decrease DFS and increase recurrence which included age (HR- 1.39 95% CI), stage (HR- 1.22, 95% CI), histopathological type (HR-1.28, 95% CI) and grade of tumor (HR-1.65, 95% CI). At multivariate analysis, FIGO stage (HR-3.9, 95% CI), histopathological type (HR-1.86, 95% CI) and grade (HR-1.11, 95% CI) having an association with decease DFS.
Conclusion: Surgical stage was one of the strongest independent prognostic factors of DFS for EOC. Increasing age, histopathology and grade are also independent predictors of decrease DFS in patient with EOC treated with current standard therapy.

Early Urological Complications After Live Related Renal Transplantation: An Update
Authors: Hossain Tohid Mohammad Saiful , Karim Tahmina 
Published: November 2020

Background: Kidney transplant is the standard of care for end stage kidney disease and associated with immunological, vascular and urological complications. Urological complications remain the most common type of surgical complication in the early post-transplant period, inspite of major procedural advances many grafts are still being lost due to same.
Objectives: The purpose of this review was to discuss the different presentations, compare various ureterovesical anastomosis techniques and provide a basic overview for the management of post-transplant urological complications hence to improve graft and patient survival.
Methods: This study was a narrative review. Recent available literature was searched by keywords. The most recent information from relevant articles were collected and reviewed. This write up was compiled after the review of articles from the last 50 years.
Results: Majority of these complications could be traced back to the time of retrieval and anastomosis of ureter. So, the high degree of suspicion, early detection, accurate diagnosis and timely management of urological complications occurring after kidney transplant were the key tasks of transplant team managing the patients. A delay in diagnosis or management of these complications could lead to morbidity to the recipient even graft loss and or mortality.
Conclusion: To minimize the early complications of post kidney transplantation high degree of suspicion and prompt intervention is needed for graft and patient survival.

Published: November 2020

BackgroundAccumulating evidence has suggested that aberrant expression of long non-coding RNAs (lncRNAs) may contribute to cancer progression in association with radioresistance. The current study aimed to identify the potential role of lncRNA MAGI2-AS3 and the underlying mechanism in its regulation of the radio-sensitivity of esophageal cancer cells.Methods and ResultsInitially, we detected high expression of HOXB7 from microarray-based gene expression profiling of esophageal cancer. Then, we identified the interactions among MAGI2-AS3, HOXB7, and EZH2 by dual-luciferase reporter gene assay, RNA pull-down assay, RIP assay and ChIP assay. HOXB7 was highly-expressed, while MAGI2-AS3 was poorly-expressed in esophageal cancer tissues and cells. The effect of MAGI2-AS3 and HOXB7 on esophageal cancer cell proliferation and apoptosis as well as tumorigenicity of radioresistant cells was examined by gain- and loss-of-function experiments. Interestingly, MAGI2-AS3 down-regulated HOXB7 through interaction with EZH2, which promoted cell apoptosis and inhibited proliferation and radio-resistance. Besides, down-regulation of MAGI2-AS3 exerted a promoting effect on these malignant phenotypes.ConclusionTaken together, our results reveal the potential role of MAGI2-AS3 over-expression in controlling esophageal cancer resistance to radiotherapy by down-regulating HOXB7, this providing a candidate biomarker for resistance to radiotherapy.
Land-Use Changes and the Effects of Oil Palm Expansion on a Peatland in Southern Thailand
Authors: Srisunthon Prapawadee , Chawchai Sakonvan 
Published: November 2020

Tropical peatlands are one of the largest reservoirs of terrestrial organic carbon. However, present-day tropical peat swamp forests are under threat by anthropogenic disturbances and have already been widely degraded. Anthropogenic pressures on peatland ecosystems have resulted in ecological and biogeochemical changes and the release of carbon to the atmosphere. In Southeast Asia, the conversion of peatlands to oil palm plantations has accelerated significantly during the last 2 decades. This research analyzed direct and indirect land-use changes (DLUC and ILUC) that have been associated with oil palm expansion and anthropogenic impacts in the Princess Sirindhorn Wildlife Sanctuary (PSWS), Narathiwat, southern Thailand. Our analysis is based on land-use and land-cover data of the Land Development of Thailand from two different periods: 2000–2009 and 2009–2016. For the purpose of comparison, the data were reclassified into 12 types of land use: oil palm, para rubber, paddy field, abandoned paddy field, orchard, other agriculture lands, wetlands and peatlands, mangrove, evergreen forest, water area, build-up area, and unused area. In addition, the area of net change due to DLUC and ILUC was calculated, and carbon stock changes were estimated from above- and below-ground biomass and soil organic carbon. The results show that the total oil palm plantation area has increased from 0.04% in 2000 to 6.84% in 2016, because of a Thai government policy promoting the use of biodiesel and increasing capacity of palm oil production in 2005. Paddy field, evergreen forest, wetlands, and peatlands were the main areas being replaced. The clearance of natural forest greatly increased in the period of 2000–2009. The ILUC indicates that the expansion of oil palm plantations invades other croplands (paddy field, para rubber, and orchard). The results demonstrate that the conversion of natural landscapes (evergreen forest, mangrove, wetlands, and peatlands) to oil palm plantations at Princess Sirindhorn Wildlife Sanctuary area had a negative effect, with carbon stock changes of 4 million Mg C during 2000–2016 (0.25 million Mg C/year). Given the significance of carbon stock changes arising from land-use changes, this research highlights the need for sustainable land-use management and long-term monitoring.
