Published: October 2022

Abstract
Present work contains a 3-D Finite Element model created in Abaqus to examine bond behavior in controlled/non-corroded Reinforced Concrete beams. Study evaluated the compatibility between corrosion levels and beam deflections. Cohesive surface-based interaction method is applied to the Data obtained from recent studies in which corrosion was induced by accelerated corrosion technique. The cohesive surface-based interaction approach has been found to be suitable for simulating the interfacial binding between reinforcement bars and the concrete. Analysis of Control and corroded beams along with mesh sensitivity are used for the validation of the work. Study demonstrated that experimental and analytical research are in good agreement with considered level of corrosion and corresponding deflections. The modelling outcomes can be used to validate the bond behaviour of Reinforced concrete cantilever beams without considering the influence of stirrups.

Abstract
Introduction:
The prevention of child abuse and neglect is an urgent matter given the serious effects persisting into adulthood, and the increased risk of the offspring of abused children being abusive themselves. Intervening as early as possible may prevent abuse that can begin in infancy. Although several systematic reviews have investigated the effects of interventions on populations who are at increased risk for perpetrating child abuse and neglect, few studies have focused on women or interventions that start during perinatal periods. This study aims to describe a systematic review to examine the effects of interventions to prevent child abuse and neglect that begin during pregnancy and immediately after childbirth (less than one year). The study will involve performing a systematic review and meta-analysis based on the latest research articles and a broader literature search.
Methods and analysis:
The protocol was prepared using the 2015 statement of Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The review will follow Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. The literature search will be performed using the MEDLINE, PsycINFO, Embase, and Cochrane Central Register of Controlled Trials databases from inception onward. Randomized controlled trials of interventions that begin during pregnancy or the first year postpartum, designed to prevent child abuse and neglect in families who are at increased risk for these issues, will be included. Data collection, quality assessment, and statistical syntheses will be conducted by following the methods in the protocol that are predefined. Any index of child maltreatment will be included as a primary outcome. A meta-analysis and sub-group analyses will be considered based on the characteristics of interventions.
Ethics and dissemination:
This study does not require ethical approval. The findings will be presented at conferences and will be submitted to a peer-reviewed journal.
Systematic review registration: PROSPERO CRD42021266462

Strengths and limitations of this study
- This study will systematically review and analyze evidence on the effectiveness of interventions to prevent child abuse and neglect among pregnant and postpartum women.
- This study will investigate a broader range of electronic bibliographic databases, including MEDLINE, PsycINFO, Embase, and CENTRAL, using a systematic search strategy.
- The study will be based on the latest articles, and the publication period will not be limited.
- As we will only include peer-reviewed articles written in English, a publication bias may occur that excludes related research published in other languages and gray literature.
- We will only access limited databases, and furthermore, using different methods to assess child abuse and neglect may cause heterogeneity among studies.
Oilseeds, innovation and the 4th agricultural revolution: USAID's perspective
Authors:   U.S. Agency for International Development, Michener Michael 
Published: October 2022

USAID has been shaping innovations in agriculture and advancing development in agribusiness and rural communities since its inception in 1961 (USAID, 2013, 2019). In 1968, USAID Administrator William Gaud announced a €œgreen revolution€ with the inception of high yield varieties, driven by Norman Borlaug's research with wheat, inputs and better policies in the developing world. Today, we are at the forefront of a fourth agricultural €œrevolution€ to support a growing population with new knowledge and digital innovations. USAID supports research to enhance agriculture with better seeds, capacity building and technology transfers affecting the value chain, from smallholder farmers through to processors. The USAID Feed the Future Innovation Labs draw on top U.S. universities and research institutions to overcome the world's greatest challenges in food security. As an example, oilseeds are playing an important role in the 4th agricultural revolution; the global oilseed market expanded over 220% in the short 20 years from 1990-2010. Soybean and palm oil production increased 300% in the same period (Byerlee, 2017). Oilseeds can make significant contributions to enhance livelihoods and food security, however Africa makes up less than 1% of global soybean production and holds 24% of palm cultivated land area (Goldsmith, 2019, Ordway, 2019). Africa has the highest rate of stunting in the world at 33% for children under 5 (UNICEF, 2018). Nutrient dense crops like soybean have the potential to alleviate malnutrition, particularly when processed at scale. Unlike the green revolution of the late 1960's however, USAID supports initiatives that alleviate the dynamic tension between environmental concerns, smallholder livelihoods and food security. This new agricultural revolution will be "greener" because it synthesizes criticisms of intensive industrial agriculture while applying past lessons learned. We must work together, as one team of development and industry professionals, to sustain the planet and all of its people.

Published: October 2022

An eco-friendly dry tribo-electrostatic separation technique has been investigated to produce native plant-based protein concentrates from yellow pea flour using a lab-scale tribo-electrostatic separator. In this approach, a mixed-level full factorial (32 Ã— 22) experiment was designed to evaluate the influence of process parameters on the protein content and protein separation efficiency of the resulted protein-enriched product. A multiple linear regression model was used to analyze the data along with optimizing the process with the objective of maximizing the protein separation efficiency while reaching a protein content of at least 57%. Air flow rate, milling type (Pin and Ferkar), and milling intensity were found to have statistically significant impacts on the protein content while only plate voltage had an impact on protein separation efficiency. Although plate voltage and air flow rate had no impact on the response variables, the interactions of plate voltage with milling intensity and air flow rate with plate voltage were found to be significant. The optimal conditions for air flow rate, plate voltage, milling type, and milling intensity were found to be 7 LPM, -6.5 kV with pin milled flour at the higher milling intensity. It resulted in 57.1% of protein content for the protein-enriched flour. The theoretical predictions had a good agreement with the experimental results.

Abstract

Aim:
Pediatric femoral central venous catheter insertion is sometimes difficult due to small vein size. External iliac vein (EIV) compression may provide a tourniquet effect to the femoral vein (FV) and may facilitate catheterization. This study was conducted to determine the effect of EIV compression on FV size and femoral venous catheterization success rates.

Methods:
This study had 2 parts. The first part was a single-arm experimental study. The second part was a randomized controlled trial. Children weighing 2.5–15.0 kg were included. First part: All patients received the same intervention and measurements. FV anteroposterior and medial-lateral diameters were measured by ultrasound without EIV compression, after which EIV was compressed using the assistant’s finger, and FV diameters were measured. Second part: Patients were randomized into compression and control groups. The compression group received EIV compression during femoral venous catheterization. The control group did not receive the compression.

Results:
A total of 30 patients (15 in each group) participated. EIV compression significantly increased FV anteroposterior diameter (3.36 ± 1.01 mm with compression, 2.39 ± 0.76 mm without compression, mean difference = 0.97 mm, 95% CI = 0.73, 1.21, P &lt; 0.001) and medial-lateral diameter (4.58 ± 1.40 mm with compression, 3.86 ± 1.32 mm without compression, mean difference = 0.72 mm, 95% CI = 0.43, 1.01, P &lt; 0.001). Catheterization success rates were not different between groups.

Conclusions:
EIV compression increased FV size, but the effect on femoral venous catheterization success rates was inconclusive due to a small sample size.

Precursores electroacústicos: lo que las músicas electroacústicas les deben a otras músicas y a otras artes
Authors: Reinoso Daniel 
Published: October 2022

Llamamos músicas electroacústicas a las distintas variantes de arte sonoro que utilizan fundamentalmente la cadena electroacústica como instrumento musical. Podemos ubicar sus orígenes en la reciente historia de la música contemporánea y, por una especie de “selección artificial”, derivaron en lo que hoy son.
La intención de este trabajo es pasar revista a la memoria de esta selección; desandar el camino que éstas recorrieron al ir conformándose. Atenderemos en cada tipo, las búsquedas de apertura del lenguaje musical, la tecnología condicionante en sus momentos y las posibles influencias de las otras disciplinas artísticas anteriores y contemporáneas a su desarrollo.

Planning comparison of imrt versus vmat techniques for boost treatments during breast cancer radiotherapy
Authors: M 1 Thirumal 
Published: October 2022

In this study, the IMRT and VMAT boost plans for 10 left-sided breast cancer patients were analysed using DVH parameters and treatment delivery parameters. Before treatments, IMRT and VMAT plans were made for every patient and they were evaluated qualitatively by noting the dose distributions slice-by-slice and then quantitatively by analysing various DVH parameters. The results were noted and statistically analysed for the significant differences in the mean values.It was noted that the VMAT plans resulted in significantly higher mean doses as well as higher near-maximum doses. The doses to the Heart, contralateral breast, contralateral lung, were found to be statistically similar in both techniques. However, the mean doses to the ipsilateral lung were significantly lesser in IMRT techniques. Similarly, the IMRT technique gave lesser low dose volume V5%(%) than that of VMAT. In contrast, VMAT plans required significantly less MUs per fraction as compared to IMRT plansIt is concluded that both IMRT and VMAT plans resulted in good conformation of dose with homogenous dose distribution, depending on dose-volume tolerance of the ipsilateral lung being exceeded or not, and on compliance issues of the patient during treatment, the final decision of choosing the technique is to be made.
