Authors: Widiarta I Nyoman 
Published: July 2021

<p>Pest and disease are important biotic obstacles to increase rice yield and production in Indonesia since adoption of green revolution to increase rice yield. This is partly due to the irrational use of pesticides. This paper is a review on information technology (IT) based decision support system (DSSs) in line to the integrated pest management (IPM) implementation strategy for extensionists and farmers in the fields. IPM integrates compatible control techniques to manage pest populations below the economic injury level. IT based DSSs ultimately needed so that extension workers and farmers can quickly access sources of information about pests and diseases as well as prediction of development and control techniques to implement IPM. Web based DSSs to grow healthy rice plant, pest observation and monitoring, cyber extension to make famers an expert on IPM were available, except on how to identify and utilize natural enemies are still lacking. Indonesia need to develop more IT based DSSs which accessible on web as well as on smartphone and create enabling environment for improving IPM implementation on rice not only by officer but also gradually by farmers it self to control pests and diseases of rice which are still an obstacle in increasing production.</p><p>Keywords: Rice, pest, diseases, integrated pest management, information technology</p><p> </p><p><strong>Abstrak</strong></p><p>SISTEM PENDUKUNG PENGAMBILAN KEPUTUSAN HAMA TERPADU PADA TANAMAN PADI BE RPBEANSGIESNDALIAN TEKNOLOGI INFORMASI</p><p>Sejak inovasi revolusi hijau diintroduksikan di Indonesia, hama dan penyakit tanaman semakin berkembang sehingga menghambat upaya peningkatan produktivitas dan produksi padi.

<p class="JSDLKatakunci"><strong>Abstra</strong><strong>ct</strong><strong>.</strong> The purpose of this paper is to synthesize all research results qualitatively to explore the potential of biochar as a remediation agent in swamps, including its mechanism, and effectiveness. The soil in swampland is characterized by the presence of pyrite (FeS<sub>2</sub>) which results in high acidity (soil pH &lt;3.5). The reduction process in swamps produces high amounts of ferrous iron (Fe<sup>2+</sup>) which is then released into the environment. The mechanism of iron (Fe) poisoning is indicated by the inhibition of nutrient uptake because the roots are covered with iron. This disturbes the root function as a nutrient absorber. Recent research shows that biochar could be used as an approach to reduce soil pollution in swamps through metal immobilization processes. This review paper uses a qualitative method with meta-aggregation approach based on the Francis-Baldesari method (2006). Principally, the soil remediation mechanism using biochar does not remove metals but accumulate them into hydroxide or carbonate deposits with the help of existing microorganisms. Provision of rice husk Biochar can increase the pH value reaching ≥5.0 and grain yield by 20% in intensively cultivated tidal swamps. Increasing the pH value of the soil will supports the formation of Fe hydroxide deposits which are accumulated on rice roots.</p><p class="JSDLKatakunci"> </p><p><strong>Abstrak. </strong>Tujuan penulisan paper ini adalah mensintesis seluruh hasil penelitian secara kualitatif untuk<strong> </strong>menggali potensi biochar sebagai bahan remediasi pada lahan rawa meliputi mekanisme, dan efektivitasnya. Tanah di lahan ini dicirikan oleh keberadaan pirit (FeS<sub>2</sub>) yang menghasilkan keasaman tinggi (pH tanah &lt;3,5). Proses reduksi di lahan rawa menghasilkan besi ferro (Fe<sup>2+</sup>) dalam jumlah tinggi dan dilepaskan ke lingkungan. Mekanisme keracunan besi (Fe) ditunjukkan dengan terhambatnya serapan hara karena perakaran diselimuti oleh besi sehingga fungsi akar sebagai penyerap unsur hara terganggu. Penelitian terbaru menunjukkan bahwa pemanfaatan biochar sebagai salah satu pendekatan untuk mengurangi pencemaran tanah di lahan rawa melalui proses immobilisasi logam. Paper review ini menggunakan metode kualitatif berdasarkan metode Francis-Baldesari (2006) dengan pendekatan metaagregasi (meta-aggregation). Mekanisme remediasi tanah menggunakan biochar prinsipnya tidak menghilangkan logam tetapi mengakumulasinya menjadi endapan hidroksida maupun karbonat dengan bantuan mikroorganisme yang ada. Pemberian Biochar sekam padi dapat meningkatkan nilai pH mencapai ≥5,0 dan hasil gabah sebesar 20% di lahan rawa pasang surut yang intensif dibudidayakan. Peningkatan nilai pH tanah mendukung pembentukan endapan hidroksida Fe yang diendapkan pada akar padi.</p>

Published: July 2021

As part of the University of Manitoba Libraries Outreach Services, the Winnipeg Regional Health Authority (WRHA) Virtual Library provides library services to hospitals, health centres, community health agencies, and personal care homes throughout the city of Winnipeg, Manitoba. All services of the WRHA Virtual Library, including the collection, are entirely virtual, though staff are physically located in the University’s health library. In March 2020, shortly after the World Health Organization declared the novel coronavirus disease (COVID-19) pandemic, libraries around the world started closing their doors and staff were required to work from home. The virtual infrastructure of our services and collections required no changes in how our patrons accessed the Virtual Library and a smooth transition was expected, but the sudden shift to working from home revealed gaps. This article discusses the unique experience of the WRHA Virtual Library transitioning to a completely virtual environment, the previous reliance on the University’s physical infrastructure, and the inequities identified between librarians and library technicians.

Published: July 2021

Abstract
To gain insights into tissue-specific gene expression in multicellular systems, gene expression profiles are required to be precisely linked with spatial information. Here, we establish a hight-depth spatial transcriptomics method, photo-isolation chemistrty (PIC), which is able to isolate gene expression profiles only from UV-irradiatied region out of whole tissue section. This method performs reverse transcription on tissue sections using photocaged oligo DNAs. After the UV irradiation, the cDNAs in the irradiated regions are allowed to be amplified and sequenced, thereby providing gene expression profiles linked with spatial information.
Changes in Chemical Composition of Dissolved Organic Matter in Solar Ponds From Salt Lake Brine

Published: July 2021

Abstract
The abundance and chemical composition of dissolved organic matter (DOM) in the brine of solar ponds influence efficiency of mineral extraction and rates of brine evaporation, and cause undesired odor and color of the products. In this paper, we report an investigation on changes of DOM compositions in solar ponds from salt lake brine through different approaches. The results showed that the DOM was primarily composed of carbohydrates, aliphatic and aromatic compounds. Dissolved organic carbon (DOC) analysis revealed that the concentration of DOC in solar pond increased with exposure time, and up to 15−fold upon evaporation/irradiation of salt lake brine. Analyses with the elemental composition, Fourier transform infrared spectroscopy (FTIR) and cross polarization magic angle spinning (CP/MAS) 13C nuclear magnetic resonance (NMR) indicated that the relative abundance of aliphatic compounds (including functionalized ones) increased in solar pond process, while an opposite phenomenon was observed for carboxylic acid moieties, aromatics and carbohydrates. Pyrolysis−gas chromatography−mass spectrometry (Py−GC−MS) revealed that most of the DOM in salt lake brine contained methylene chain, terpenoid-like, carbohydrate and/or aromatic structures. The presence of some sulfur-containing organics implied some anaerobic biotic decays, but microbiological processes were probably subordinate to photo-induced DOM transformations. In the salt lake brine, exposure-driven decay decreased the abundance of polysaccharides and increased that of mono- and polyaromatic pyrolysis products. Finally, the implications and guidelines for removing DOM from brine in the process of brine resource exploitation were discussed.

Abstract
An efficient and new dynamic model of two-link flexible manipulator connected and controlled by flexible joints i.e., prismatic and revolute pairs has been developed to explore the modal analysis to study tip-trajectory characteristics and subsequently investigate the nonlinear steady-state responses under harmonic motion at flexible joints. The governing equations including joint dynamics have been derived using extended Hamilton’s principle. Modal parameters have been graphically presented to highlight the influences of various system parameters on the determination of eigenfrequencies and eigenspectrums. Obtained reduced order equations have then used to study the trajectory characteristics of tip displacements, angular and actuator positions by imparting the appropriate actuator force and joint torque. Further, nonlinear studies have been carried out to compute the steady state responses and their stability and local bifurcation by using 2nd order method of multiple scales. Investigation of the influences of various design parameters on the nonlinear stability and local bifurcation of steady state responses have been demonstrated and those results have been found to be in good agreement with numerically obtained findings. The obtained results find very useful in the applications of long-reach robot manipulators performing complex operations assigning with translating and rotary motion together.

Abstract
Objective: To observe the effect of exercise training on cognitive functions of diabetic rat model. Methods: Male SD rats were given a high fat and high sugar diet, except for control group. After 4 weeks, 35 mg /kg STZ was intraperitoneally injected to establish type 2 diabetes model rats. After successful modeling, rats were randomly divided into the model group, model + exercise group. Animals performed 5 days of consecutive treadmill exercise (60 min/day) with 22 m/min speeds for 60 days. After 60 days, behavioral tests were conducted by Morris water maze method. then rats were weighed and blood samples were obtained to detect blood glucose. Some animals were sacrificed to prepare serum to detect glycosylated hemoglobin. Brain tissues were taken to detect the protein expressions of HMGB1-/RAGE-/NF-κB signal pathway by Western Blot. The brains of other animals were perfused and taken for RAGE and NF-κB immunohistochemical staining.Results: Compared with control group, escape latency and probe distance in the model group were significantly prolonged, swimming time in the target quadrant was significantly shortened, and the number of crossing platform was significantly reduced. The average grayvalues of NF-κB and RAGE were significantly decreased. Expressions of HMGB1,RAGE,p-NF-кBp65 and p-IкBα were significantly up-regulated(P<0.05 or P<0.01). Compared with the model group, escape latency and probe distance were significantly shortened, swimming time in the target quadrant was prolonged and increased the number of crossing platform, it also reduced the fasting blood glucose, increased body weights, reduced the level of glycated hemoglobin, and significantly increased the mean grayvalues of NF-κB and RAGE. The protein expressions of HMGB1, RAGE, p-NF-кBp65 and p-IкBα were decreased in model + exercise group.Conclusion: Exercise training can ameliorate the cognitive dysfunction of diabetic rats, its mechanism may be related to reducing blood glucose, reducing the level of glycated hemoglobin and improving the HMGB1 /RAGE/NF-κB pathway in the brain tissue.

Abstract
BackgroundBorder malaria remain as one of the greatest challenges facing elimination in China. Malaria control interventions among migrant population across border relies on personal protection from mosquito bites. Understanding the knowledge of the link between mosquitoes and malaria will inform malaria control and elimination programmes on those targeted risk population.MethodsFrom March 2018 to September 2019, 108 migrant workers from Vietnam were enrolled conducted in Ning Ming County in Guangxi. Each people were interviewed using the structured questionnaires. Blood samples were collected and sent to the PCR detection and sequenced.ResultsMalaria knowledge was poor with 19.4% on transmission, 23.2% on clinical symptoms, 7.4% on awareness of the risk of death, and 14.8% on awareness of prevention methods. No significant difference was found among occupations except for migrant workers, whose knowledge rate were higher than other occupations. Most of the participants (80.6%) had mosquito nets and 73.2% of them had 2 persons who were under the bed net at night. The usage rate of bed-nets accounted for over 49.1%. For parasitological study, 5.6% (n = 6) of all participants infected tested positive for malaria, and no statistically significant differences in the positive rate among different age, sex, family size, nationality, occupation and different behaviors.ConclusionThe health education focus on the high risk population such as migrant workers and forest goers should be strengthened. Therefore, health education based on verbal communication such as web, radio, and mobile phone may be required under the COVID-19 pandemic situation. Further risk assessment of importation and proactive case detection should also be carried out, not only in Ningming County, but also in other border counties in Guangxi, which aimed to timely detect the patients, as well as the asymptomatic infections that could cause the re-establishment of malaria.

Abstract
Periodically, heavy rainfall associated with extreme El Niño events severely damage the Peruvian road-network. This study aims to assess the socio-economic effects of these non-frequent but recurrent climate shocks. For this purpose, we build a Computable General Equilibrium model that addresses the consequences of El Niño-related damages through an increase in interregional transportation costs and a negative externality effect on activities’ output, which has been estimated beforehand using a firm database. For designing simulation scenarios over a ten-year period where extreme El Niño events occurs at random as observed in the past in Peru, we model the occurrence of these events as a stochastic process with a VAR representation based on historical climatic data. Within this framework, we first show that such events constitute a significant one-off disaster risk for the country, threatening shifts of − 2.8% in GDP and + 1.9% in poverty rates with an annual probability p = 1.4%. We further show that they also present a longer-term risk, leading to average annual deviations from normal trend by − 0.8% in GDP and + 0.4% in poverty rate with a probability p = 12.6% over a ten-year period. However, we finally show that Peru might reduce these risks in constructing more disaster-resilient road infrastructure.

Abstract
Background: Uterine Corpus Endometrial Carcinoma (UCEC) ranks fourth among female cancers in the world. Frustratingly, the 5-year survival rates for advanced patients are only 17%. KDM4B is overexpressed or dysregulated in a variety of cancers and could be associated with tumor progression and poor prognosis. Therefore, we performed bioinformatics analysis and in vitro assays to assess the role of KDM4B in UCEC. In addition, its relevance to immune cells in the tumor microenvironment was explored.Methods: The mRNA level and protein level of KDM4B in UCEC was evaluated using the TCGA, HPA and GEO database. Immunohistochemistry and western blotting were used to verify the protein expression level of KDM4B in two batches of clinical samples. Kaplan-Meier curves, Univariate and multivariate analysis were used to assess the correlation between KDM4B expression and prognosis. GO and KEGG were used to predict the function and mechanism of KDM4B, and four immunity related database were used to explore their relevance to the tumor immune microenvironment.Results: Firstly, the present study showed that KDM4B was significantly overexpressed in UCEC from several databases at the mRNA and protein levels, respectively. Immunohistochemistry and western blotting confirmed the abnormally overexpression of KDM4B. In addition, upregulation of KDM4B was associated with different clinicopathological prognostic factors. Secondly, overexpression of KDM4B was also associated with shorter OS and PFS. Univariate and multivariate analyses confirmed that KDM4B was an independent prognostic factor for poor prognosis. Then, GO and KEGG analysis revealed that KDM4B is enriched in biological processes and cellular signaling pathways closely related to immunity. Finally, KDM4B expression was closely associated with immune cell infiltration and immune checkpoints and it may be a new immune-related potential oncogene in UCEC.Conclusions: KDM4B may be a new potential oncogene for UCEC patients. It is of clinical significance that KDM4B may not only be used to assess the clinical prognosis of UCEC patients but may also be a target for immunotherapy or gene targeted therapy.
