Authors: Olivares-Hernández Alejandro , Escala-Cornejo Roberto A. , García-Domínguez Araceli R. , Cruz-Hernández Juan J. 
Published: April 2020

Introduction Immunotherapy represents one of the fundamental points on the oncological treatments. The increasingly frequent use of these treatments has allowed us to observe various side effects in up to 10 to 20% of patients and endocrine side effects are one of the most commonly described. We report a case of diabetic ketoacidosis in a 46-year-old male patient as debut of type-1 diabetes mellitus secondary to treatment with nivolumab.
Case Report The patient who went to the emergency department due to abdominal pain associated with vomiting 48 hours previously. Diagnosed 4 years ago of clear cell renal carcinoma stage IV, due to pulmonary metastatic involvement, the patient was under treatment with nivolumab. Urgent blood and urine tests were performed in the urgency evaluation; the patient was diagnosis of severe diabetic ketoacidosis. Pancreatic endocrine complications are observed in 0.5 to 5% of the patients with immunotherapy. Among the adverse effects described are alterations in baseline fasting glycaemia and the possible development of type-1 diabetes. These molecules increase the activity of T-cells, amplify the cellular immune activity with the consequent increased immune response, which can lead to a destruction of the pancreatic β-cells. Strict endocrine control is necessary during immunotherapy treatment; however, there are no clear indications for the monitoring of pancreatic reserve levels or glycemic control. For these reasons, we propose the need for closer and regular monitoring of C-peptide and HbA1c (glycosylated hemoglobin) to prevent the development of the diabetes and their complications.
The Rise and Fall of the Aid Effectiveness Norm
Authors: Brown Stephen 
Published: April 2020

AbstractThis article analyzes the rise and fall of the aid effectiveness norm, using the lens of Finnemore and Sikkink’s norm ‘life cycle’. I argue that, although donors and recipients endorsed the founding principles, the norm was only feebly internalized: they were unwilling to overcome their reluctance—and important disincentives—to substantially change their practices on the ground. After the norm cascaded, the donor-led process sought to gain legitimacy and diffuse the norm more broadly by trying to bring in a wider range of actors through norm substitution. These changes failed to convince emerging donors to engage and caused the norm to decay to the point where it ceased to constitute a norm. This case highlights the importance of refining the life cycle model to take into account weak internalization and the potential existence of a second phase in which norms decline and potentially die.

Published: April 2020

Abstract
Drought tolerant sorghum varieties cultivation on dryland areas is one of the potential sources of plant biomass to be used for bioethanol production. East Nusa Tenggara which has a short month of rainfall and mainly consists of drought-prone areas is suitable for sorghum to thrive where most other food crops simply withered. Eleven sorghum genotypes were evaluated on the dry land of East Flores in East Nusa Tenggara with treatment in the different applications of organic liquid fertilizer. Results showed that genotypes values were significantly different in all traits observed, and the interaction factors between fertilizer and genotypes had a significant effect on all traits except panicle length and width. The application of liquid organic fertilizer, however, did not significantly affect traits in both plant and stem biomass. Super 2 genotype showed the highest stem biomass value and differed significantly compared to other genotypes, even though fertilized treatment obtained less yield (29.87 t.ha−1) compared to without fertilizer (44.11 t.ha−1). Pearson correlation between all observed traits showed that stem biomass was significantly highly correlated to various traits, such as number of internodes (r = 0.77), plant height (r = 0.74), stem diameter (r = 0.72), and plant biomass weight (r = 0.97).

Abstract
The basic principle of ohmic heating is the dissipation of electrical energy into heat which causes warming effect and membrane cell permeability. The aim of this study was to explore the tools that use the ohmic heating method to extract essential oils from lemongrass. The extraction process of citronellal and geraniol was using several temperature variations which were at 90 °C using aquadest (citronellal 31.77% and geraniol 18.49%) and at 80 °C using ethanol-n-hexane (citronella 31.75% and geraniol 18.65%). The ohmic heating method based extraction process resulted in a variety of electrodes that were producing the alpha-cadinol compounds which were not found in the control. The average electrical power in the treatment using copper plates were 1287.7 watts and 1116.04 watts. Moreover, the result showed that the produced citronella oil has fulfilled the criteria for citronella oil quality standard according to SNI 06-39531995 which has a density value in the range of 0.850 - 0.892 g/cm3

Abstract
This research aims to test the performance of palm oil foaming agent solution (POFAS) in a laboratory for the prevention and fire extinguishing of a peatland surface. The materials used in this research were POFAS formulas, i.e. NF45 and NF46, at various concentrations of 1%, 2%, 3%, and 6%. Measuring tools and machines used were patternator and spraying measurement tools, a knapsack mist blower for the foam method, a knapsack electric sprayer, and an air blower for the non-foam method. Results of this research showed that the minimum droplet diameter, maximum droplet density, maximum effective spraying width, and minimum effective spraying debit were 452.06 μm, 136.22 droplets cm−2, 72 cm, and 1.47 liter min−1 for foam method, and 452.24 μm, 148.33 droplets cm−2, 56 cm, and 1.84 liter min−1 for non-foam method. In the foam method, the NF45 formula with a concentration of 2% was the most effective POFAS formula for the prevention and extinguishing of the peatland surface because it has the largest ability to cover the peat surface pore spaces. In the non-foam method, the NF46 formula with a concentration of 3% was the most efficient POFAS formula because it has a large effective spraying width and the smallest effective spraying debit so that this POFAS application was the shortest and most efficient in POFAS consumption.

Published: April 2020

Abstract
Carbon dioxide (CO2) has been stated as one of major contributor to climate change and affects marine ecosystems. Among other CO2 capturing technology, adsorption is widely used due to its numerous advantages. Rubber seed shell (RSS), an agriculture waste from rubber plantation was used as precursor for preparing activated carbon (AC) by chemical activation using Malic acid as activating agent for CO2 adsorption. In this research, the AC was characterized and analysed by SEM, Micrometric ASAP 2020, TGA and FTIR instruments. The optimum condition was found at activation temperature of 600 °C, sample A. Results from specific surface and porosity analyzer shows the AC total pore volume, specific surface area and diameter were 0.2635 cm3/g, 480.5692 m2/g and 2.1937 nm, respectively. The CO2 adsorption studies showed the CO2 uptake for the AC was 2.26 mmol/gwhich is better most agricultural wastes’ and commercial AC. It was found that malic acid helps to prolong the thermal stability of AC. The presence of a new FTIR peak in samples indicated N-H stretching and C=N stretching might due to remaining malic acid on the surface which increased the CO2 affinity and was an attractive source for CO2 adsorption applications.

Published: April 2020

Abstract
Accurate assessment of reservoir sanding risk is a key link in the optimization design of offshore oil-gas fields. Based on the Monte Carlo risk probability assessment method, three factors affecting sand production, such as rock Poisson’s ratio, rock density and acoustic time difference, are considered. At the same time, combined with the existing sand production index prediction theory, the probability distribution calculation model of sand risk is established and analyzed. The established prediction model is used to analyze the sand production case. The model was combined with the logging data and seismic data of some layers in Oilfield HZ 32-5 to form the probability distribution map of the sand production index of the J22, J50 and K08 horizons in HZ 32-5 Oilfield. The probability of different sand production levels of the three reservoir rock horizons is predicted, and the corresponding sand control risk prevention and control plan is formulated. Through the on-site application of HZ 32-5 Oilfield, it is proved that the model can more accurately assess the sand production risk in offshore oilfields, and has a good guiding significance for the design of oil-gas well completion schemes.

Authors: Yang Wei , Cao Yuemeng 
Published: April 2020

Abstract
The development of disruptive technologies in the Marine field is an important means to seize the commanding heights of international scientific and technological competition and requires policy support from the government. Based on the concept of strategic niche management, this study quantitatively studied the construction and evolution of policy protection space during the development of China’s deep-sea carrier equipment technology from 2001 to 2018. The research shows that :(1) from 2001 to 2018, three different types of policy tools were used in relevant technology policies, with the proportion of “expect establishment” 62.50%, “network construction” 6.58% and “learning and experiment” 30.92%, but the use of policy tools was not balanced. (2) on the whole, the growth trend of the number of deep-sea submersible development is lower than the trend of the use of policy tools, indicating that the use of policy tools has a certain impact on the development of deep-sea vehicle technology, but the effect is limited. From 2010 to 2018, the number of deep-sea vehicles developed and the number of policy tools used increased by three times and four times respectively compared with that from 2001 to 2009, indicating that the use of policy tools after 2010 has a significant role in promoting the development of deep-sea vehicle technology and industry. (3) China’s deep-sea delivery equipment industry is still in the stage of technological niche, and the use of protective policy tools such as network construction should be strengthened.

Published: April 2020

Abstract
Aiming at the problem that it is difficult to effectively identify rolling bearing faults, a method for motor rolling bearing faults based on IMF sample entropy and particle swarm optimization SVM (PSO-SVM) is proposed. Firstly, the complementary collective empirical mode decomposition (CEEMD) is applied to the adaptive decomposition of bearing vibration signals to obtain a group of Intrinsic Modal Functions (IMFs). Then the sample entropy of the IMF component containing the main fault feature information was calculated to obtain the sample entropy matrix of the signal component, which was input as the feature vector into the particle swarm optimization SVM for training and testing. Through the analysis of simulation and experimental data, the method has a high identification accuracy for fault types.

Published: April 2020

Abstract
High pressure output pumps are one of the critical equipment in LNG terminals. Since the health condition of high pressure output pumps has a direct influence on production capability of the terminal, health assessment for these pumps in real time plays an important role on guaranteeing efficient productivity of LNG terminals. Using condition monitoring data, a machine learning based health assessment model for high pressure output pumps is proposed. Health features are constructed based on time domain statistical analysis and wavelet packet decomposition, and a SVR model is trained to calculate a health index from extracted features. Actual operating data in Qingdao LNG terminal are used for model validation. Results show that the calculated health indices are sensitive to faults and anomalies of the pumps, and are good indicators of pump health status. The proposed model also shows capability of early warning for some sudden failures, which can be valuable in the operation and maintenance management of LNG terminal equipment.

Abstract
Miniaturized lasers with wavelength variability are of crucial importance for various ultracompact photonic devices. Here, we report fine tunable microlasers built by mechanically stretching the flexible microcavities and elastic substrate. The flexible microcavities fabricated by precisely printing dye-doped polymer solution on elastic substrate, enabled whispering-gallery-mode laser under optical pumping. Furthermore, on account of the outstanding structural flexibility of organic materials, reversible wavelength-tunable laser can be realized through adjusting the shape of microcavity via mechanical stretching the elastic substrate. The results will provide guidance for the rational design of photonic devices with novel performances based on the characteristic of organic flexible materials.

Published: April 2020

Abstract
Spatial interpolation widely is used to predict rainfall in ungauged location. There are two methods of spatial interpolation, deterministic method such as Inverse Distance Weighting (IDW) method and geostatistics such as kriging. Daily rainfall in the tropical Indonesian maritime region such as Sulawesi is generally uneven. Although, in a location has heavy rainfall, a zero rainfall can be found in adjacent places. It makes choosing suitable spatial interpolation method for ungauged rainfall prediction is difficult. The aim of this research is evaluate the impacts of the rainy season to the interpolation method. Root mean square (RMSE) and correlation is used as statistical parameter to determine the goodness of interpolation method. The result shows that heavy rain event has big impact to interpolation, both IDW and kriging. Log transformation can little improve in RMSE in rainy season, but not recommended in dry seasons.The most biggest deviation of the interpolation result spreads in south west coast, plain at middle of Sulawesi and north part of the Bone Gulf in January and only south west coast of Sulawesi and north part of the Bone Gulf in dry season July.
