<p><strong>Capacity and Capability Differences on Rice and Shallot Farmers and the Impact on the Farming Productivity. </strong><em>During the last two decades there has been no stepping up in the production of rice and shallots farming. This is caused by low use of research innovation as well as the slow delivery of innovations to users. On the other hand, most of farmers' perceptions on extension workers are not entirely positive. The extension activities have not answered farmers need, and low impact on improving farmers' capacity and capability. The study objectives were (1) to analyze the differences on rice and shallot farmers capacity and capability, (2) to analyze the factors affected the farmers capacity and capability, and (3) to formulate a strategic approach to increase farmers capacity, capability and their farm productivity. The research was carried out through a structured survey of rice farmers in Subang and Boyolali Districts (n=270), and shallot farmers in Cirebon, Brebes, and Grobogan districts (n=249), from May to December 2018. The results of study showed that there was differences in capacity dan capability between rice farmers and shallot farmers affecting productivity among farmers and production gaps at the farm level. The use of innovation as a result of extension activities, had a high opportunity to increase in farmers' production and income. On shallots farmers the The productivity difference among farmers on shallot commodity was relatively high, because of the gap in the application of innovation in farming activities, so that the increase in capability did not directly affect on the production and income of farmers. </em></p>
Preliminary Screening and Formulation of New Generation Nanoparticles for Stable Pickering Emulsion in Cold and Hot Heavy-Oil Recovery
Authors: Wang Zhenjie , Babadagli Tayfun , Maeda Nobuo 
Published: May 2020

Summary
Injecting water with chemicals to generate emulsions in the reservoir is a promising method in the enhancement of heavy-oil recovery because the formation of oil-in-water (O/W) emulsions significantly reduces oil viscosity. Nanoparticles (NPs) (Pickering emulsions) can be used for this purpose as a cost-effective alternative to expensive surfactants; however, such Pickering emulsions need to be stable for successful applications. The objective of this study is to screen the effective emulsifier for O/W emulsions from a broad range of solid NPs and identify suitable Pickering emulsifying agents (e.g., adjusting pH or salt concentration) that can render emulsions stable at relevant conditions, and to investigate how a range of physical parameters, such as particle concentration, water/oil ratio (WOR), and temperature affect emulsion stability.
Five NPs—including cellulose nanocrystals (CNCs), silica, alumina, magnetite, and zirconia—were tested on their capabilities of stabilizing O/W emulsions through glass vial screening tests under various pH and salinity conditions. The screening results showed that the CNC could become an effective emulsifier by either adjusting pH or salinity. In addition, zeta potential measurements were conducted to explain the observations. The stabilization mechanisms of CNCs were studied through an epifluorescent transmitted microscope showing that the formation of a dense particle layer around the oil droplets, as well as a network in the continuous phase, were the two main mechanisms accounting for the high stability of the emulsions stabilized by CNCs. The effects of particle concentrations on the emulsion stability were studied quantitatively by analyzing the droplet-size distributions calculated by the open-source ImageJ software, with the results showing a sharp decrease in droplet size, followed by a smooth change as the particle concentration increased. For the WOR effect, phase inversion from O/W to water-in-oil (W/O) emulsions was observed when the oil content was more than 0.6. The thermal stability of emulsions was studied both macroscopically by glass bottle tests and microscopically through a microscope, both of which show that the CNC-stabilized emulsions remained thermally stable up to 100°C. The rheological properties of both aqueous dispersions of CNCs and the corresponding O/W emulsions were also measured under various salinity conditions. The results showed that the salinity had a great impact on the viscosity of the CNC suspension and the typical shear-thinning behavior of Pickering emulsions.
This study provides an option to enhance emulsion stability without surfactants, which will reduce the costs and facilitate field applications of emulsion flooding in heavy-oil recovery.
Study on Debonding Issue of Cementing Interfaces Caused by Perforation with Numerical Simulation and Experimental Measures

Published: May 2020

SummaryThe debonding of cementing interfaces caused by perforation will increase the possibility of microannuli/microcrack propagation during hydraulic fracturing. This phenomenon will pose a threat to well integrity not only with stimulation operations but also subsequent long-term production. The objective of this work is to quantitatively investigate the debonding degree of cementing interfaces after perforation. A numerical model was used to simulate the process of the wellbore being penetrated by the perforating gun. Then, a real dimensional perforation experiment was conducted with a circular target specimen. The numerical debonding area of the casing/cement interface was verified by this experiment with the method of computerized tomography (CT).The numerical-simulation and experiment results show that the cementing-interface debonding is mainly caused by the displacement difference between the casing, cement sheath, and formation during perforation. The debonding area and the microannuli of the casing/cement interface are larger than those of the cement/formation interface. Sensitivity analysis reveals that the debonding area of the cementing interface shows a positive relationship with the hexogen explosive (RDX) load and the elastic modulus of casing. Therefore, the casing with lower elastic modulus should be preferred to reduce the debonding area of the cementing interface caused by perforation if the principal casing-design criteria were met.

Published: May 2020

Abstract
Background The largest proportion (amongst total newborns requiring inpatient care) is constituted by healthcare needs of small and sick neonates. This has to be delivered by a team of skilled and competent healthcare professionals. Very few comprehensive packages exist for management of premature and sick newborns. WHO-CC, AIIMS with the help of nearly thirty-five leaders in neonatology and nursing champions caring for preterm infants developed a multimodal educational package with philosophy of “Do No Harm” Methods The creation of the educational package included formative research for assessing health facility readiness, defining content deliverables and their layout. The modules thus developed were then field tested and validated. Each of the ten modules was then organized as pre-defined learning objectives, deliverables including text, videos, webinars, posters and job aids. The entire content is available as self-directed web based E-learning platform ( www.pretermcare-eliminatingrop.com ) designed to make users aware of the best care practices for preterm infants.Results The inputs from the field testing workshop on content, interaction and teaching learning methodology were incorporated in the educational package. The participants felt that the content was explicit and clearly defined and the workshop facilitated free interaction. The online platform has 2500 registered participants registered till date. Nearly 80% of the participants felt that quality of information presented, organization of content and the degree to which the examples related to real scenarios was excellent to exceptional. Discussion The learners are actively involved in the learning process and teachers are actually facilitators rather than ‘fact generators.’ The package focuses on the transformative learning strategies and the impact is likely to be revolutionary once it is taken to scale. In addition, the online web based learning platform along with its multimedia contents can be easily used for distance learning following which the participant can come for skill learning.

Abstract
Background

The kidney has a rich endoplasmic reticulum system. A close relationship exists between endoplasmic reticulum stress (ERS) and diabetic kidney disease (DKD). The current study aimed to investigate serum glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer binding protein homologous protein (CHOP) concentrations in type 2 diabetes mellitus (T2DM) Chinese patients, especially those with microalbuminuria.
Methods

We evaluated the relationships between serum GRP78 or CHOP levels and DKD. We recruited 67 patients with T2DM and 63 control subjects. We determined serum GRP78 and CHOP concentrations by ELISA, collected anthropometric data, and measured biochemical parameters in a clinical laboratory.
Results

Compared with control groups, Chinese T2DM patients showed decreased serum levels of GRP78 [0.21 (0.16–0.24) vs. 0.16 (0.16–0.19) ng/mL, p < 0.01] and CHOP [3.8 (3.0–5.5) vs. 5.5 (3.7–7.9) ng/mL, p < 0.01]. Reduction in GRP78 and CHOP serum levels was more pronounced in patients with more severe categories of microalbuminuria. Amounts of serum GRP78 correlated directly with serum fasting c-peptide, cystatin-c (cys-c), creatinine (Cr), blood urea nitrogen (BUN), and uric acid, and inversely with glomerular filtration rates. Serum CHOP level was positively correlated with age, Cr, BUN, cys-c, urinary microalbumin/creatinine (UmALB/Cr), and eGFR. Serum GRP78 was predicted independently by Cr, BUN, serum uric acid, eGFR, and cys-c, while CHOP depended on age, Cr, BUN, serum uric acid, eGFR, UmALB/Cr, and cys-c. After controlling for confounding factors, GRP78 and CHOP expression was significantly associated with DKD (binary logistic regression, p < 0.01).
Conclusions

T2DM patients showed increased serum GRP78 and CHOP concentrations. Receiver operating characteristic (ROC) areas under the curve for predicting DKD based on GRP78 and CHOP were 0.686 [95% CI: 0.558–0.813] and 0.670[0.524–0.816], respectively.

Published: May 2020

Abstract
Background

Hyperglycemic Emergency (HE) denotes critical cases of decompensated diabetes mellitus (DM). Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are the extreme cases of HE. This study aims to assess the treatment outcome of HE and predictors.
Method:

Four-year medical records of DM patients admitted for HE at Hiwot Fana Specialized University Hospital (HFSUH) were reviewed retrospectively. The data abstraction tool was adapted from the preceding studies. Data were entered into and cleaned by Epi-InfoTM7 software. The statistical analysis was executed using the statistical package for social sciences software (SPSS) version 24. Chi-square test and student’s t-test were done to compare categorical and continuous variables. Logistic regression with the level of α set at 0.05 and AOR of 95% CI was done to determine the predictors. Statistical significance was established at AOR ≠ 1 within a 95% CI and P-value < 0.05. The model was verified using the Hosmer-Lemeshow goodness of fit test (P = 0.392).
Results

This study included 321 eligible patients. The median duration of hospital stay was 7 days. The pooled HE mortality was 16.5%; 21.4% of HHS and 11.1% of DKA died. Infection (AOR = 3.74, 95% CI: 1.85–7.57, P < 0.001), comorbidity (AOR = 2.95, 95% CI: 1.34–6.48, P = 0.007), and lower admission Glasgow Coma Scale score ≤ 8 (AOR = 2.58, 95% CI: 1.17–5.71, P = 0.019) were the independent predictors of HE mortality.
Conclusion

Mortality and duration of hospital stay stand high among DM patients admitted for HE at HFSUH. Infection, comorbidity, and lower admission GCS ≤ 8 are the independent predictors of HE mortality. Operative strategies targeting the predictors ought to be devised to control the morbidity and mortality among DM patients hospitalized for HE.
