Pemberatan Pidana bagi Petugas Lembaga Pemasyarakatan yang Terlibat Peredaran Narkotika Di Lingkungan Lembaga Pemasyarakatan
Authors: Saskara Hanindya Seno
Published: September 2020

Dewasa ini, penyalahgunaan narkotika sangat marak terjadi di Indonesia. Penyalahgunaan narkotika tidak hanya dilakukan oleh masyarakat dengan kemampuan ekonomi yang mapan, bahkan masyarakat dengan kemampuan ekonomi yang rendahpun turut juga melakukan hal tersebut. Hal ini diakibatkan karena akses dalam mendapatkan narkotika relatif mudah karena banyak oknum yang tidak bertanggung jawab yang secara hukum tidak memiliki wewenang untuk menyediakan narkotika. Peredaran gelap narkotika pun bahkan terjadi di dalam Lembaga Pemasyarakatan yang notabene merupakan tempat yang terisolasi dan berada dalam pengawasan yang sangat ketat. Penyalahgunaan narkotika tidak hanya dilakukan oleh masyarakat sipil saja bahkan Pegawai Negeri Sipil khususnya Petugas Lembaga Pemasyarakatan juga bisa melakukan penyalahgunaan narkotika. Hal ini dibuktikan dengan maraknya keterlibatan pegawai negeri sipil dalam penyalahgunaan narkotika. Keterlibatan Petugas Lembaga Pemasyarakatan dalam penyalahgunaan narkotika menimbulkan stigma negatif dimana tingkat keprofesionalitasan Petugas Lembaga Pemasyarakatan sebagai Pegawai Negeri Sipil diragukan. Seharusnya memberikan contoh yang baik bagi masyarakat. Namun terkait aturan pemidanaan bagi Petugas Lembaga Pemasyarakatan belum diatur secara jelas dalam Undang-Undang Nomor 35 Tahun 2009 Tentang Narkotika sehingga dari permasalah tersebut dibuatlah penelitian terkait pemberatan pidana bagi Petugas Lembaga Pemasyarakatan.
Pertanggungjawaban Bank Dalam Perkara Tindak Pidana Pencucian Uang yang Tidak Menjalankan Prinsip Kehati-Hatian
Authors: Istiqomah Istiqomah
Published: September 2020

Tindak Pidana Pencucian Uang yang dikenal dengan istilah money laundering merupakan proses dimana aset-aset pelaku terutama asset tunai yang diperoleh dari suatu tindak pidana dimanipulasikan sedemikian rupa sehingga aset tersebut seolah-olah berasal dari sumber yang sah. Bank sebagai lembaga penyedia jasa keuangan menjadi incaran dan sarana untuk melakukan tindak kejahatan termasuk tindak pidana pencucian uang. Adanya prinsip kehati-hatian bank salah satunya bertujuan untuk mencegah bank menjadi media tindak pidana pencucian uang, turunan dari prinsip kehati-hatian bank adalah prinsip mengenal nasabah yang telah berkembang menjadi prinsip customer due dilligence (CDD) dan enhanced due dilligence (EDD) wajib diterapkan oleh bank, kegiatan berupa identifikasi calon nasabah dan memantau karakteristik transaksi setiap nasabah, serta melaporkan apabila ada transaksi mencurigakan sesuai dengan peraturan perundang-undangan. tindakan bank yang tidak menjalankan prinsip tersebut akan dikenakan hukuman sebagaimana yang diatur dalam peraturan perundang-undangan mengenai prinsip mengenal nasabah. Maka seharusnya bank bertanggungjawab ketika tidak melaksanakan prinsip kehati-hatian bank berkaitan dengan upaya pencegahan tindak pidana pencucian uang.
Tinjauan Yuridis Hubungan Seksual Sesama Jenis
Authors: Al Nohandi Qidam
Published: September 2020

Dalam penulisan artikel ini penulis membahas masalah pencabulan sesama jenis kelamin terhadap orang yang telah dewasa. Dalam hal ini terkait tindak pidana pencabulan masuk kedalam kejahatan kesusilaan yang diatur dalam Buku II Bab XIV. Kejahatan kesusilaan ini merupakan kejahatan yang berhubungan dengan masalah kesusilaan yang berarti masalah adab atau perilaku. Ruang lingkup dari delik kesusilaan sangat luas, salah satunya yaitu terkait perbuatan pencabulan tersebut. Penulisan ini di latarbelakangi karena begitu banyaknya penyimpangan seksual yang terjadi dalam masyarakat yang menafsirkan kebebasan seksual sampai dengan menentukan orientasi seksual setiap masing-masing individu. Penelitian ini bertujuan untuk mengetahui penerapan hukum pidana terkait pelaku pencabulan sesama jenis terhadap orang telah dewasa. Karena dalam hal ini tidak ada aturan yang secara implisit mengatur terkait perbuatan ini. Pada dasarnya delik pencabulan sesama jenis ini sama seperti pencabulan yang ada di KUHP, karena bentuk dari perbuatannya sama yang membedakan bahwa dalam pencabulan sesama jenis ini baik pelaku maupun korban memiliki jenis kelamin yang sama. Misalnya homoseksual ataupun lesbian. Oleh karena itu perbuatan pencabulan sesama jenis terhadap orang dewasa ini dapat dijerat dengan ketentuan Pasal 289 KUHP dan 290 angka 1 KUHP.

Authors: Ramadhanti Syifa
Published: September 2020

Dalam penyelenggaraan pemerintahan desa memiliki dua lembaga yang sangat penting yang pertama kepala desa dan Badan Permusyawaratan Desa (BPD). BPD berperan sebagai mitra dari kepala desa dalam menjalankan pemerintahan desa serta dalam membentuk peraturan desa. BPD memiliki fungsi sebagai penyalur aspirasi masyarakat desa serta memiliki tugas menggali aspirasi masyarakat desa. BPD dipilih melalui dua cara yaitu dengan musyawarah keterwakilan dan pemilihan langsung. Dalam proses pemilihan BPD sering terjadi kecurangan yang dilakukan oleh beberapa pihak, dan mengakibatkan calon anggota BPD yang mencalonkan diri dirugikan haknya. contohnya kecurangan terjadi di Desa Jaten Kabupaten Karanganyar, Desa Kalaena Kabupaten Luwu Timur dan Desa Karya Mukti Kabupaten Batanghari. Dengan kerugian yang dialami calon anggota BPD tersebut, mereka melakukan sebuah upaya untuk menegakkan nilai-nilai keadilan. Setiap orang memiliki hak untuk berpolitik, termasuk calon anggota BPD yang mencalonkan dirinya merupakan realisasi dari hak berpolitik. Apabila hak berpolitik seseorang dirugikan tentunya seseorang tersebut dapat melakukan sebuah upaya hukum untuk mendapatkan keadilan. Upaya yang dapat dilakukan oleh para calon anggota yang merasa dirugikan dapat dilakukan melalui mekanisme hukum (litigasi) ataupun non-lititgasi.

The aim of this study was to determine the difference in the estrous performance of Aceh cows with repeat breeding. In this study, ten Aceh cows were used, consisting of five normal cows (KI) and five repeat breeder cows (KII). The criteria of the cows used were 3-5 years old, had a body weight of 150-250 kg, and had at least two regular cycles. All cows in both groups were estrous synchronized with 5 ml PGF2a intramuscularly. Estrous observation was done visually twice a day at 8 am and 4 pm. Estrous intensity was assessed by scoring. The results showed that the intensity, onset, and duration of estrous (KI vs KII) were respectively (18.00 ± 5.70 vs 17.60 ± 6.65), (40.00 ± 14.96 vs 41.60 ± 30.67 hours), and (78.40 ± 10.43 vs 80.00 ± 40.39 hour). To conclude, there was no difference in the intensity, onset, and duration of estrous between normal Aceh cows and those with repeat breeding.

Published: September 2020

Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy of median nerve. The current development of global COVID-19 pandemic urges medical rehabilitation services to deliver a comprehensive approach amidst the physical distancing period. This case report aims to investigate the feasibility and efficacy of implementing telerehabilitation to the conventional therapy in the treatment of CTS. A 51-year old female presented with post carpal tunnel release of the left hand, and chronic-severe CTS on right hand. We maintained 5 weeks rehabilitation programs of combined telerehabilitation and face-to-face rehabilitation therapy and evaluation. The patient showed good compliance with the programs and achieved the intended goals within 5 weeks of therapy. Patient showed improvement (in pain, range of motions, hand functions, and ADLs). Telerehabilitation combined with conventional therapy were effective and feasible in treating patient with bilateral (left post-release and right chronic-severe) CTS. The use of telerehabilitation may add accessibility while reducing physical contact in order to minimize the risk of transmission of COVID-19.

ACE2 receptors are reported to have an important role in myocardial injury in Covid-19. Direct myocardial toxic effect of virus, myocarditis, cytokine injury, microangiopathic injury related to virus infection may cause myocardial injury and eventually troponin levels increase. Those mechanisms are; unstable plaques in coronary arteries resulting in myocardial hypoxia, upregulation of ACE2 receptors in coronary arteries and cardiac tissue, direct toxic effect of virus towards myocytes, systemic inflammation, myocardial interstitial fibrosis, excessive immune response to interferon, increased cytokine release from helper T lymphocytes which lead to myocardial injury. In this reported case, clinical course was mild and outcome was good, patient was followed in ward and he did not need intensive care.

Published: September 2020

This article discusses the unique experiences and methods of independent examination of the level of communicative (specifically receptive and productive) English language skills of the first year undergraduate students studying English as the first foreign language in a Russian university, who previously passed the Unified State Exam (USE) in English. The results analyzed came from the tests the students took at the beginning of their first academic year. This study attempts to lay the foundations for the transition to level-oriented learning or to introduce differentiation in groups where students’ levels range widely – from A1 to C1. The assessment of the English language proficiency of students studying Philology, Linguistics, Foreign Regional Studies, and Pedagogy was carried out in the format the B2 First Cambridge exam (FCE). The results of the assessment were used to analyze their level of language knowledge and language skills according to the Common European Framework of Reference for Languages: Learning, Teaching, Assessment (CEFR). A number of typical mistakes made by students were revealed, based on which the students as well as their teachers were offered a number of recommendations to improve each of the skills.

Authors: Dinis Maria Lurdes , Gonçalves Maria Inês
Published: September 2020

This work aimed to assess and characterize the air quality in what concerns particulate pollution in urban-industrial environments. The main objectives were to study the spatial variability of the deposition flux of particulate pollution identifying areas with higher deposition, associate the variability with climatological variables and with possible surrounding emitting sources. The method for collecting the deposited particles was based on the standard NF X 43-007. Sampling for particulate pollution took place between April 2015 and February 2016, through seven sampling campaigns. Maps of the spatial dispersion for the particulate pollution were obtained through statistics and geostatistics techniques. Elemental identification by scanning electron microscopy (SEM) was also used but only in two sampling campaigns. The results show that the sampling campaigns that took place during hot and dry periods, 2nd and 3rd, present higher deposition flux: 2.04 g/(m2 x month) and 1.72 g/(m2 x month), respectively. Lower deposition fluxes were registered in the 6th and 7th campaigns: 0.23 g/(m2 x month) and 0.24 g/(m2 x month), respectively. It was also observed a recurrent high deposition at specific sampling points which may be due to both the nearby road traffic and the presence of chimneys. SEM analysis allowed to associate repetitive element deposition, at the same sampling point, to the same emitting source.

Published: September 2020

Rationale: Examining trends in patient characteristics, processes of care and outcomes, across an epidemic, provides important opportunities for learning. Objectives: To report and explore changes in admission rates, patient characteristics, processes of care and outcomes for all patients with COVID-19 admitted to intensive care units (ICUs) in England, Wales and Northern Ireland. Methods: Population cohort of 10,287 patients with COVID-19 in the Case Mix Programme national clinical audit from 1 February to 2 July, 2020. Analyses were stratified by time period (pre-peak, peak, post-peak) and geographical region. Multivariable logistic regression was used to estimate differences in 28-day mortality, adjusting for patient characteristics over time. Main results: Admissions to ICU peaked simultaneously across regions on 1 April, with ongoing admissions peaking ten days later. Compared with pre- and post-peak periods, patients admitted during the peak were slightly younger but had greater respiratory and renal dysfunction. Use of invasive ventilation and renal replacement reduced over time. Twenty-eight-day mortality reduced from 43.5% (95% CI 41.6% to 45.5%) pre-peak to 34.3% (95% CI 32.3% to 36.2%) post-peak; a difference of −8.8% (95% CI: −5.2%, −12.3%) after adjusting for patient characteristics. London experienced the highest admission rate and had higher mortality during the peak period but a greater reduction in post-peak mortality. Conclusion: This study highlights changes in patient characteristics, processes of care and outcomes, during the UK COVID-19 epidemic. After adjusting for the changes in patient characteristics and first 24-hour physiology, there was substantial improvement in 28-day mortality over the course of the epidemic.

Published: September 2020

With the every passing day, the demand for data traffic is increasing and this demand forces the research community not only to look for alternating spectrum for communication but also urges the radio frequency planners to use the existing spectrum smartly. Cell size is shrinking with the every upcoming communication generation which makes the base station placement planning complex and cumbersome. In order to make the next-generation cost-effective, it is important to design the network in such a way which utilizes minimum number of base stations while ensure coverage and quality of service. This paper aims at develop a new approach using hybrid metaheuristic and metamodel applied in multi-transmitter placement planning (MTPP) problem. We apply radial basis function (RBF) metamodel to assist particle swarm optimizer (PSO) in a constrained simulation-optimization (SO) of MTPP to mitigate the associated computational burden of optimization procedure. We evaluate the effectiveness and applicability of proposed algorithm in a case study by simulating MTPP model with two, three, four and five transmitters.

Published: September 2020

Epigenetic aging has been found associated with a number of phenotypes and diseases. Few studies investigated its effect on lung function in relatively older people. However, this effect has not been explored in younger population. This study examines whether lung function at adolescent can be predicted with epigenetic age accelerations (AAs) using machine learning techniques. DNA methylation based AAs were estimated in 326 matched samples at two time points (at 10 years and 18 years) from the Isle of Wight Birth Cohort. Five machine learning regression models (linear, lasso, ridge, elastic net, and Bayesian ridge) were used to predict FEV1 (Forced Expiratory Volume in one second) and FVC (Forced Vital Capacity) at 18 years from feature selected predictor variables (based on mutual information) and AA changes between the two time points. The best models were ridge regression (R2 = 75.21% ± 7.42%; RMSE = 0.3768 ± 0.0653) and elastic net regression (R2 = 75.38% ± 6.98%; RMSE = 0.445 ± 0.069) for FEV1 and FVC, respectively. This study suggests that the application of machine learning in conjunction with tracking changes in AA over life span can be beneficial to assess the lung health in adolescence.
Significance and Distribution of Apatite in the Doig Phosphate Zone
Authors: Lacerda Silva Pablo , Bustin R. Marc
Published: September 2020

The Doig Phosphate Zone (DPZ) is a phosphate-bearing marine unit located at the base of the Doig Formation, in the Triassic section of the Western Canada Sedimentary Basin. The DPZ has a maximum thickness of 90 m and extends across northeastern British Columbia and western central Alberta. In this study we characterize the significance and interpret the origin of apatite in the DPZ, through mineralogical and geochemical analyses, thin section study and field emission-scanning electron microscopy. The occurrence of apatite in the DPZ is not evenly distributed, but restricted to discrete 10 to 20 cm thick beds, located near the base of the DPZ. Phosphorites are of two types: grainstones composed primarily of unconformity-bounded coated grains, and intraclastic phosphorites composed of detrital silt-sized grains and apatite coated grains in a cryptocrystalline phosphatic matrix. The phosphorite beds are records of stratigraphic condensation due to low detrital input during transgression. The erosionally-truncated phosphatic coated grains and intraclasts are interpreted to be a result of various phases of phosphatization, exhumation, erosion reworking, winnowing and redeposition in alternating quiescence and storms or bottom currents. The abundance of pyrite and chalcophile trace elements, as well as the low concentration of proxy elements for organic matter productivity and preservation, are further evidences of stratigraphic condensation, with sulfidic pore water development and extensive organic recycling promoted by biological activity during the long exposure times. The phosphorites were formed under oxygenated water conditions, as suggested by the depletion in Ce and presence of a diverse benthic fauna.
Does Immediate Removal of Urinary Catheter Prevent Urinary Morbidities Following Cesarean Section: A Prospective Randomized Study
Authors: Maskey Upasana , Marahatta Rita , Vaidya Biloni
Published: September 2020

Objective: Urinary catheters are known cause of urinary morbidities. The longer the catheter is retained, the greater the risk for contamination and infection. An increasing body of literature suggests routine practice of catheterization and retaining it for 24 hours does not add any procedural advantage. Thus, we sought to study outcomes in relation to early vs. delayed removal of urinary catheters following cesarean section. Methods: We randomly assigned 116 patients into early and delayed removal of urinary catheter groups. In the early group, catheter was removed immediately after the procedure and in the delayed removal group, catheter was removed 24 hours later. Clinical outcomes were measured in terms of significant bacteriuria 72 hours postop, voiding difficulties, urinary retention, mobilization time, length of hospital stay, and patient satisfaction. Results: Study revealed higher incidence of bacteriuria in the delayed removal group (32.8% vs. 15.5%, P = 0.030). Urinary frequency was also higher (34.6% Vs. 8.6%, P=0.001). However, there were no difference between the two groups in other urinary complaints including dysuria and urgency (P = 0.103 & P = 0.087). Urinary retention was more frequent in the early group, but difference was not significant (P = 0.080). Patients with immediate removal of the urinary catheter had early ambulation and early discharge from hospital (P = 0.001 and P = 0.040) and were generally satisfied with the procedure (P= 0.010). Conclusion: Our study showed that immediate removal of urinary catheter was associated with lower urinary complications, shorter length of hospitalization and associated cost.

Authors: Miñana-Signes Vicente , Monfort-Pañego Manuel
Published: September 2020

The aim of this study was to analyze the level of specific back-health-related physical activity and exercise knowledge. This is a cross-sectional study. A representative sample of 1500 students were recruited with a confidence level of 95% and an accepted standard error of ±2.53%. Individuals were aged between 13 and 18 years old (mean age= 15.18; SD = ±1.446). Self-reported questionnaires were used to record back-health-related physical activity and exercise knowledge concerning back care in adolescents. The level of specific knowledge of back health education related to physical activity and exercise in adolescents was low (X = 2.05, SD = ±2.264). Only 10.9% of the students passed the specific knowledge test, achieving a grade equal or superior to 5. The boys average score was higher (X = 2.17, SD = ±2.312) than the girls (X = 1.94, SD = ±2.212) with statistically significant differences (p = .048). The level of specific knowledge increased with age (F = 11.531; p < .001). High school students have a low level of specific knowledge. Physical Education teachers should apply the conceptual content properly. Knowledge is the first step towards changing behavioral habits. Back care education in the school curriculum is recommended.
Taxonomy and Phylogenetic Research on Ralstonia solanacearum: A Complex Pathogen with Extraordinary Economic Consequences
Authors: Paudel Sujan , Dobhal Shefali , Alvarez Anne M. , Arif Mohammad
Published: September 2020

The bacterial wilt pathogen, first known as Bacillus solanacearum, has undergone numerous taxonomic changes since its first description in 1896. The history and significance of this pathogen is covered in this review with an emphasis on the advances in technology that were used to support each reclassification that finally led to the current separation of Ralstonia solanacearum into three genomic species. Frequent name changes occurred as methodology transitioned from phenotypic, biochemical, and molecular studies, to genomics and functional genomics. The diversity, wide host range and geographical distribution of R. solanacearum has resulted in its inclusion in a “species complex” as genomic analyses of elucidated phylogenetic relationships among strains. Current advances in phylogenetics and functional genomics now open new avenues for research into the epidemiology and control of the devastating bacterial wilt disease.
Perspectives on Adversarial Classification

Published: September 2020

Adversarial Classification (AC) is a major subfield within the increasingly important domain of adversarial machine learning (AML). Most approaches to AC so far have followed a classical game-theoretic framework. This requires unrealistic common knowledge conditions untenable in the security settings typical of the AML realm. After reviewing such approaches, we present alternative perspectives on AC based on Adversarial Risk Analysis.
Public Participation in Smart-City Governance: A Qualitative Content Analysis of Public Comments in Urban China
Authors: Gao Zhe , Wang Siqin , Gu Jiang
Published: September 2020

Public participation is crucial in the process of urban governance in smart-city initiatives to enable urban planners and policy makers to take account of the real public needs. Our study aims to develop an analytical framework using citizen-centred qualitative data to analyse urban problems and identify the areas most needed for urban governance. Taking a Chinese megacity as the study area, we first utilise a web-crawling tool to retrieve public comments from an online comment board and employ the Baidu Application Programming Interfaces and a qualitative content analysis for data reclassification. We then analyse the urban problems reflected by negative comments in terms of their statistical and spatial distribution, and the associative factors to explain their formation. Our findings show that urban problems are dominantly related to construction and housing, and most frequently appear in industry-oriented areas and newly-developed economic development zones on the urban fringe, where the reconciling of government-centered governance and private governance by real estate developers and property management companies are most needed. Areas with higher land price and a higher proportion of aged population tend to have less urban problems, while various types of civil facilities affect the prevalence of urban problems differently.

In this paper, we proposed the numerical method called the variational iteration orthogonal collocation method (VIOCM), for the approximate solution of the deadly Corona virus model using Mamadu-Njoseh polynomials as basis functions. The proposed method is an elegant mixture of the variational iteration method (VIM) and the orthogonal collocation method (OCM). It was observed that the proposed method converges rapidly to the exact solution even as N increases. This suggests that the use of orthogonal polynomials as trial functions for the SEIR model is indeed an effective approximant as it produces the analytic solution at just few iterations. Resulting numerical evidences were compared with the standard variational iteration method as available in literature. All computational frameworks were executed with MAPLE software.

Published: September 2020

Stormwater management is a key urban issue in the world, in line with the global issues of urban sprawl and climate change. It is urgent to investigate the effectiveness in managing stormwater with different strategies for maintain urban resilience. A method based on a storm water management model (SWMM) was developed for assessing the control of stormwater runoff volume and the percentage removal of suspended solids by implementing a Sponge City strategy. An interdisciplinary approach was adopted incorporating Low Impact Development (LID) with urban Green Infrastructure and Gray Infrastructure paradigms in a typical old residential community in Suzhou, China. Four types of sponge facilities for reducing stormwater runoff were bio-retention cells, permeable pavements, grassed pitches, and stormwater gardens. The simulation results indicate that the stormwater pipe system can meet the management standard for storms with a five-year recurrence interval. The volume capture ratio of annual runoff is 91% and the reduction rate of suspended solids is 56%. This study demonstrates that Sponge City strategy is an effective approach for managing stormwater, particularly in old and densely populated urban areas. Implementing spongy facilities with a LID strategy for stormwater management can significantly enhance urban water resilience and increase ecosystem services.
Money Often Costs Too Much: A Study to Investigate The Effect Of Twitter Sentiment On Bitcoin Price Fluctuation
Authors: Verma Mitul , Sharma Pritish
Published: September 2020

Introduced in 2009, Bitcoin has demonstrated a huge potential as the world’s first digital currency and has been widely used as a financial investment. Our research aims to uncover the relationship between Bitcoin prices and people’s sentiments about Bitcoin on social media. Among various social media platforms, micro-blogging is one of the most popular. Millions of people use micro-blogging platforms to exchange ideas, broadcast views, and to provide opinions on different topics related to politics, culture, science, and technology. This makes them a potentially rich source of data for sentiment analysis. Therefore we chose one of the busiest micro-blogging platforms, Twitter, to perform sentiment analysis on Bitcoin. We used ELMo embedding model to convert Bitcoin-related tweets into a vector form and SVM classifier to divide the tweets into three sentiment categories - positive, negative, and neutral. We then used the sentiment data to find its relation with Bitcoin price fluctuation using the linear mixed model.

Planktonic foraminiferal biomineralization intensity, reflected by their shell calcite mass, affects global carbonate deposition and is known to follow the climate cycles by being increased during glacial stages and decreased during interglacial ones. Here we measure the dissolution state and the mass of the shells of the planktonic foraminifera species Globigerina bulloides from a Tropical Eastern North Atlantic site over the last two glacial-interglacial climatic transitions and we report no major changes in plankton calcite production with the atmospheric pCO2 variations. We attribute this consistency in foraminifera calcification to the climatic and hydrological stability of the tropical regions. We however recorded increased shell masses midway through the penultimate deglaciation (Termination II). In order to elucidate the cause of the increased shell weights we performed δ18O, Mg/Ca and μCT measurements on the same shells from a number of samples surrounding this event. We find that shells of increased mass are internally contaminated by sediment infilling and that shell weights are responding to local hydrographic changes.
Carbon Balance in Salt Marsh and Mangrove Ecosystems: A Global Synthesis
Authors: Alongi Daniel M.
Published: September 2020

Mangroves and salt marshes are among the most productive ecosystems in the global coastal ocean. Mangroves store more carbon (739 Mg CORG ha-1) than salt marshes (334 Mg CORG ha-1), but the latter sequester proportionally more (24%) net primary production (NPP) than mangroves (12%). Mangroves exhibit greater rates of gross primary production (GPP), above-ground net primary production (NPP) and plant respiration (RC) with higher PGPP/RC ratios, but salt marshes exhibit greater rates of below-ground NPP. Mangroves have greater rates of subsurface DIC production and, unlike salt marshes, exhibit significant microbial decomposition to a soil depth of 1 m. Salt marshes release more soil CH4 and export more dissolved CH4 , but mangroves release more CO2 from tidal waters and export greater amounts of POC, DOC and DIC to adjacent waters. Both ecosystems contribute only a small proportion of GPP, RE (ecosystem respiration) and NEP (net ecosystem production) to the global coastal ocean due to their small global area, but contribute 72% of air-sea CO2 exchange from the world’s wetlands and estuaries and contribute 34% of DIC export and 17% of DOC + POC export to the world’s coastal ocean. Thus, both wetland ecosystems contribute disproportionately to carbon flow of the global coastal ocean.

Technological advances in game-mediated robotics provide an opportunity to engage children with CP and other neuromotor disabilities in more frequent and intensive therapy by making personalized, programmed interventions available 24/7 in children’s homes. Though shown to be clinically effective and feasible to produce, little is known of the subjective factors impacting acceptance and of such assistive/rehabilitative gamebots by their target populations and their families. This research describes the conceptualization phase of an effort to develop a valid and reliable instrument to guide the design of A/R gamebots. We conducted in-depth interviews with 8 children with CP and their families who had trialed an A/R gamebot for 28 days in their homes to understand how existing theories and instruments were either appropriate or inappropriate to measuring the subjective experience of A/R gamebots. Key findings were the importance of differentiating the paradigm of rehabilitative from that of assistive technology, the need to incorporate the differing perspectives of children with CP and those of their parents into A/R gamebot evaluation, and the potential conflict between the goals of preserving the quality of the experience of game play for the child while also optimizing the intensity and duration of therapy provided during play.

Understanding the importance of gut microbiota (GM) in non-alcoholic fatty liver disease (NAFLD) has raised the hope for therapeutic microbes. We have shown that high hepatic fat associated with low abundance of Faecalibacterium prausnitzii in humans and further, administration of F. prausnitzii prevented NAFLD in mice. Here, we aimed to target F. prausnitzii by prebiotic xylo-oligosaccharides (XOS) to treat NAFLD. First, the effect of XOS on F. prausnitzii growth was assessed in vitro. Then, XOS was supplemented or not with high (HFD) or low (LFD) fat-diet for 12-weeks in Wistar rats (n=10/group). XOS increased F. prausnitzii growth having only minor impact on the GM composition. When supplemented with HFD, XOS prevented hepatic steatosis. The underlying mechanisms involved enhanced hepatic β-oxidation and mitochondrial respiration. 1H-NMR analysis of caecal metabolites showed that compared to HFD, LFD group had healthier caecal short-chain fatty acid profile and the combination of HFD and XOS was associated with reduced caecal isovalerate and tyrosine, metabolites previously linked to NAFLD. Caecal branched-chain fatty acids associated positively and butyrate negatively with hepatic triglycerides. In conclusion, our study identifies F. prausnitzii as a possible target to treat NAFLD with XOS. The underlying preventive mechanisms involved improved hepatic oxidative metabolism.

Published: September 2020

Проблема перспективы $n$ точек (PnP), или обратная пространственная фотограмметрическая засечка, состоит в нахождении положения и ориентации модели камеры центральной проекции по заданным пространственным координатам данных
точек и соответствующим координатам их проекций на снимок. В связи с имеющимися приложениями в области робототехники и машинного зрения представляют интерес прямые безытерационные методы решения такой задачи. Известный
общий метод прямого безытерационного решения задачи PnP в случае четырех
опорных точек ($n=4$) требует двойной линеаризации и выглядит несколько громоздко. В настоящей работе предложено другое более простое решение данной задачи для случая $n=4$. Предложенный метод обеспечивает уменьшение требований к
вычислительным ресурсам, необходимым для решения данной задачи. В случае
большего числа опорных точек решение, полученное для четырех точек, может
быть использовано как начальное приближение с последующим применением итераций Гаусса-Ньютона или в схеме RANSAC.
О трехмерном численном моделировании гидродинамической и гравитационной неустойчивости протопланетного диска

Рассматривается трехмерная газодинамическая модель протопланетного диска, который вращается вокруг гравитирующего центра. Моделируется динамика малых
возмущений во вращательном сдвиговом потоке. Развитие начальных азимутальных возмущений скорости вращения приводит к образованию спиральных рукавов
плотности, а самогравитация увеличивает ее локальные максимумы, создает гравитационную неустойчивость и фрагментацию диска. Полученные результаты представляют интерес для теории образования протопланетных систем.

The processing of coffee can be classified into 3 types namely: dry, semi-wet and wet processing. And then, roasting is the process of forming the taste and aroma of coffee. The study was conducted at Pakuwon Experimental Station, Coffee and Cacao Processing Units, and Integrated Laboratory of Balittri, and TTPHP Laboratory of IPB Bogor, from July until October 2019. The study aimed to investigate (1) the effect of processing methods on physical quality characters of green beans, and (2) the effect of processing methods and roasting temperatures on chemical characters of coffee roasted and organoleptic characters of coffee brewed. The completely randomized design in factorial 2 factors and 3 replications was used in this study. The first factor were 3 type of processing methods (dry, semi-wet, and wet), and the second factor were 2 level of roasting temperatures (180oC and 210oC). The variables observed in the green beans were physical quality characters, while in roasted coffee were water content, caffeine content, and antioxidant activity, and in brewed coffee were organoleptic characters. Result showed that the best green beans was produced from a wet processing method with a minimum total defect value of 21.33 (quality 2). Roasting temperature has a very significant effect (p<0.01) on water content and antioxidant activity, while caffeine content is not significantly affected. Based on the results of cupping test, the best brewed coffee (final score >80.00) was obtained from the treatments of a dry, semi-wet and wet processing method with a roasting temperature of 210°C.

The coffee berry borer (CBB) Hypothenemus hampei (Coleoptera: Curculionidae: Scolytinae), is one of the main pests that cause yield losses in coffee plants. This pest directly attacks the coffee berries, both immature and ripe. The entomopathogenic fungi is one of the potential biological agents for CBB, environmentally friendly and does not kill non-target organisms. The study was conducted at the Integrated Laboratory, Industrial and Beverage Crop Research Institute, from June to October 2018. The aim of this study was to examine the effectiveness of bioinsecticide based on entomopathogenic fungus of Talaromyces pinophilus (EFTP) and vegetable oil on CBB. The completely randomized design with 31 treatments and 3 replications was used in this study. The 31th of treatments consisted of 9 formulas of bioinsecticide based on EFTP and vegetable oil, control-positive (bioinsecticide based on EFTP and water), and control- negative (Klorpirifos insecticide). Variables observed were the activities of EFTP enzyme, effectiveness of vegetable oil as a carrier material, mortality of CBB beetles, percentage of CBB attacks, percentage of hollow berries, and number of holes per 10 coffee berries. Results showed that the formula of bioinsecticide based on EFTP produce the chitinase and protease enzymes which were potential as biological agents to control CBB in vitro. Soybean oil is the most effective as a carrier material in formulating EFTP. The formula of S69MK30 and S79MK20 in concentration of 7.50% respectively have the highest potential as biological agents to control CBB. Other potential formula is S69MKT30 in concentration of 7.50%.
