Vector control of the Aedes aegypti mosquito in the pre-imago stage is strategy to reduce dengue infection. The aim of this study was to analyze the difference domestic sewage water pH to the hatchability of Ae. aegypti. This was an experimental study with a posttest only control group design. Independent variables were domestic sewage water media with pH of 6.5, pH of 7.5, pH of 8.5, and pH of 9.5 and dependent variable was egg hatchability of Ae. aegypti. The results showed that the most average number of Ae. aegypti eggs hatched into larvae was at pH 7.5 with 40.68% and the lowest at pH 5,5 with 0%. The results of the Kruskal Wallis test showed that there were differences in the pH of domestic sewage water to the hatchability of eggs of Ae. aegypti (p = 0.001). The results of the Mann–Whitney U test showed that there was a significant difference between the number of egg hatched in the pH of domestic sewage water at pH of 5,5. Research proves that the eggs of Ae. aegypti is able to hatch in domestic liquid waste media with pH range at pH of 6,5 – pH of 9,5. In the future Aedes aegypti mosquito control program is not only focus on clean water container water but also on the environment, especially drainage which has the potential to become a breeding place for Ae aegyptiKeyword : Hatchability, Ae. aegypti, Domestic Sewage Water

Sanggrahan landfill is an area used as place to collect solid waste in Temanggung Regency. The existence of a landfill to reduce waste accumulation in the environment, but on the other side a landfill can cause a problem like air pollution caused by waste decomposition. Waste pickers in the landfill have a risk respiratory disorder as a result of exposure to air pollutants. The purpose of this study was to analyze association between the use of personal protective equipment (PPE) and individual characteristics with respiratory disorders on waste pickers at Sanggrahan landfill. The type of this study was an observational analitical using a cross sectional approach. Subjects involved in this reseach were 69 waste pickers and were taken by using total sampling technique. The results showed that there were 68,12% waste pickers suffered complaints of respiratory disorder, the most of them having cough 43,4%, flu 47,8% and fever 27,5%. Chi square analyze showed that there were no association between gender(p=0,464), age (p=0,206), education (p=0,318), and smoking habit (p=0,585) with complaints of respiratory disorder. While, there were association between the working hours (p=0,039), length ofwork(p=0,025), use of PPE(p=0,0019), and the use of respiratory protective equipment (p=0,021) with complaints of respiratory disorder. It is expected that waste pickers can use full PPE such as a hats, long clothes, gloves, foot protection, and standard mask during their working activites or while working in the landfill area.

The unwanted pregnancy rate in Indonesia reached 15 percent (7% unwanted pregnancy and 8% mistimed pregnancy) in 2017. Unwanted pregnancy have an impact on increasing the risk of maternal mortality (305 per 100.000 population) and infants mortality (24 per 1.000 live births) in Indonesia, that these rates are still relatively high. This research aims to determine the relationship of several factors with unwanted pregnancy. This research is a quantitative with a cross sectional design using secondary data from the 207 IDHS. The sample used is pregnant women in Indonesia based on the 207 IDHS data as many as 1.996 respondents. Statistical analysis used chi-square test. The result showed that the highest of unwanted pregnancy occured in pregnant women who worked (3,9%), had a history of non-ideal parity or more than two children (11,1%), had used contraception (5,1%), and are breastfeeding (13,9%). Unwanted pregnancy occured equally in respondents with good and poor knowledge of reproductive health, respectively 3,7%. Chi-square analysis showed that the factors that were significantly associated with unwanted pregnancy were history of parity (p = 0,0001; OR = 18,97; 95%CI = 9,33-38,58), history of contraceptive use (p = 0,0001; OR = 5,29; 95%CI = 2,36-11,86), and breastfeeding behavior (p= 0,005; OR= 0,23; 95%CI = 0,09-0,63). The factors that were not significantly related were employment status (p = 0,804; OR = 0,904; 95%CI = 0,56-1,46 ) and knowledge of reproductive health (p = 1,0; OR = 0,012; 95%CI = 0,53-1,94). The conclusion of this study is history of parity, history of contraceptive use, and breastfeeding behavior are factors associated with unwanted pregnancy.

AbstractHeart rate variability assessment of neonates of pregestational diabetic mothers have shown alterations in the autonomic nervous system (ANS). The objective was to study the effect of maternal pregestational diabetes on ANS at the fetal stage by combining cardiac and movement parameters using a non‐invasive fetal magnetocardiography (fMCG) technique. This is an observational study with 40 participants where fetuses from a group of 9 Type 1, 19 Type 2 diabetic, and 12 non‐diabetic pregnant women were included. Time and frequency domain fetal heart rate variability (fHRV) and coupling of movement and heart rate acceleration parameters related to fetal ANS were analyzed. Group differences were investigated using analysis of covariance to adjust for gestational age (GA). When compared to non‐diabetics, the Type 1 diabetics had a 65% increase in average ratio of very low‐frequency (VLF) to low‐frequency (LF) bands and 63% average decrease in coupling index after adjusting for GA. Comparing Type 2 diabetics to non‐diabetics, there was an average decrease in the VLF (50%) and LF bands (63%). Diabetics with poor glycemic control had a higher average VLF/LF (49%) than diabetics with good glycemic control. No significant changes atp < 0.05 were observed in high‐frequency (HF) frequency domain parameters or their ratios, or in the time domain. Fetuses of pregestational diabetic mothers exhibited some differences in fHRV frequency domain and heart rate‐movement coupling when compared to non‐diabetics but the effect of fHRV related to fetal ANS and sympathovagal balance were not as conclusive as observed in the neonates of pregestational diabetic mothers.

AbstractAutophagy is important for protein and organelle quality control. Growing evidence demonstrates that autophagy is tightly controlled by transcriptional mechanisms, including repression by zinc finger containing KRAB and SCAN domains 3 (ZKSCAN3). We hypothesize that cardiomyocyte‐specific ZKSCAN3 knockout (Z3K) disrupts autophagy activation and repression balance and exacerbates cardiac pressure‐overload‐induced remodeling following transverse aortic constriction (TAC). Indeed, Z3K mice had an enhanced mortality compared to control (Con) mice following TAC. Z3K‐TAC mice that survived exhibited a lower body weight compared to Z3K‐Sham. Although both Con and Z3K mice exhibited cardiac hypertrophy after TAC, Z3K mice exhibited TAC‐induced increase of left ventricular posterior wall thickness at end diastole (LVPWd). Conversely, Con‐TAC mice exhibited decreases in PWT%, fractional shortening (FS%), and ejection fraction (EF%). Autophagy genes (Tfeb, Lc3b, and Ctsd) were decreased by the loss of ZKSCAN3. TAC suppressed Zkscan3, Tfeb, Lc3b, and Ctsd in Con mice, but not in Z3K. The Myh6/Myh7 ratio, which is related to cardiac remodeling, was decreased by the loss of ZKSCAN3. Although Ppargc1a mRNA and citrate synthase activities were decreased by TAC in both genotypes, mitochondrial electron transport chain activity did not change. Bi‐variant analyses show that while in Con‐Sham, the levels of autophagy and cardiac remodeling mRNAs form a strong correlation network, such was disrupted in Con‐TAC, Z3K‐Sham, and Z3K‐TAC. Ppargc1a also forms different links in Con‐sham, Con‐TAC, Z3K‐Sham, and Z3K‐TAC. We conclude that ZKSCAN3 in cardiomyocytes reprograms autophagy and cardiac remodeling gene transcription, and their relationships with mitochondrial activities in response to TAC‐induced pressure overload.

Published: May 2023

Abstract
This study explores the decision-making behaviour of economic actors in relation to transfer pricing by applying a three-layer practice theory. A critical review of the literature using snowball sampling and a thematic analysis of interview data from the Ministry of Finance, tax consultants and the Zimbabwe Revenue Authority bring to light novel conceptualisations and perspectives on the transfer pricing phenomenon. This study addresses scholarly gaps by exploring a confluence of legal, implementation and exploitative dimensions in transfer pricing regulation. The study also makes a novel contribution by proposing a model that could be useful to policymakers and tax authorities in ameliorating tax avoidance through transfer pricing.
Volume Integral Equations and Single-Trace Formulations for Acoustic Wave Scattering in an Inhomogeneous Medium
Authors: Labarca Ignacio , Hiptmair Ralf 
Published: May 2023

AbstractWe study frequency domain acoustic scattering at a bounded, penetrable, and inhomogeneous obstacleΩ−⊂Rd\Omega^{-}\subset\mathbb{R}^{d},d=2,3d=2,3. By defining constant reference coefficients, a representation formula for the pressure field is derived. It contains a volume integral operator, related to the one in the Lippmann–Schwinger equation. Besides, it features integral operators defined on∂Ω−\partial\Omega^{-}and closely related to boundary integral equations of single-trace formulations (STF) for transmission problems with piecewise constant coefficients. We show well-posedness of the continuous variational formulation and asymptotic convergence of Galerkin discretizations. Numerical experiments in 2D validate our expected convergence rates.

Abstract
In this work, Flammulina velutipes was used as a novel protein and fibrous structure source to prepare animal-free patties, and transglutaminase (TGase) was added to improve their functional properties. The results showed that the addition of mushroom increased the gel strength, texture profile, and sensory property of animal-free patties. However, the presence of mushroom made the microstructure of patty become loose, with large holes. Interestingly, TGase (6–8 U/g) significantly decreased the size of holes in microstructure and induced to form a uniform and compact microstructure. Because TGase decreased the content of free amino acid group and soluble protein, and induced the formation of new protein polymers with high molecular weight in SDS-PAGE results. The covalent cross-linking catalyzed by TGase helped to form a stronger gel matrix in patty, leading to the formation of patty with higher hardness, adhesiveness, chewiness, water holding capacity, and sensory scores.
Study of time-fractional delayed differential equations via new integral transform-based variation iteration technique

Published: May 2023

Abstract
The present article proposes a new-integral transform-based variational iteration technique (NTVIT) to study the behavior of higher-order nonlinear time-fractional delayed differential equations. The NTVIT is a hybrid technique that is developed via the concept of variational theory with the use of the properties of a new integral transform. The stability and convergence of NTVIT are analyzed via Banach’s fixed point theory. The effectiveness and validity of NTVIT solutions are demonstrated via the evaluation of error norms: relative/absolute errors for some test suitable delayed problems of different fractional order. The numerical experiments confirms that NTVIT is capable of producing highly accurate behaviors as compared to some existing techniques.
