Authors: Komarov Bohdan , Zinchenko Dmytro , Barabas Dmytro 
Published: January 2023

Abstract
The goal of this study was the intention to demonstrate the expediency of utilization of bamboo composites in manufacturing of aircrafts. The research and testing of the material were conducted in the laboratories of the Institute of Aerospace Technolgies (IAT) of the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”. To determine the expediency of using bamboo composite, it is necessary to conduct tests of the material for external effects and analyse economic feasibility. The main advantages of such a material are its environmental friendliness and cheapness of both raw materials and processing. This article is dedicated to analysing the results of the research on the mechanical characteristics and economic aspects. Bars of different sizes, different materials, and different degrees of processing were used for the analysis. The results of the testing conducted have showed that the strength characteristics of a bamboo composite are higher than that of the majority of wood species. At the same time, bamboo elements are lighter judging by weight characteristics. The undisputable advantage of their usage is a powerful and widespread structure of existing manufacturing which does not require creation of new processing machinery.

Abstract
Purpose

This study aimed to explore whether the mode of nutrition intervention delivery affected participant goal achievement in a three-arm randomised controlled trial of early and intensive nutrition intervention delivered to upper gastrointestinal cancer patients.

Methods

Newly diagnosed upper gastrointestinal cancer patients were recruited from four tertiary hospitals in Melbourne, Australia. Participants in the intervention groups received a regular nutrition intervention for 18 weeks from an experienced dietitian via telephone or mobile application (app) using behaviour change techniques to assist in goal achievement. Univariate and multiple regression models using STATA determined goal achievement, dose, and frequency of contact between groups. A p value <0.05 was considered statistically significant.

Results

The telephone group (n=38) had 1.99 times greater frequency of contact with the research dietitian (95% CI: 1.67 to 2.36, p<0.001) and 2.37 times higher frequency of goal achievement (95% CI: 1.1 to 5.11, p=0.03) compared with the mobile app group (n=36). The higher dose (RR 0.03) of intervention in the telephone group compared with the mobile app group positively impacted on participant goal achievement (95% CI: 0.01 to 0.04, p<0.001).

Conclusion

Telephone nutrition intervention delivery led to higher frequency of goal achievement compared to the mobile app intervention. There was also a higher number of behaviour change techniques employed which may have facilitated the greater goal achievement. Mobile app based delivery may have poorer acceptance in this population with high levels of withdrawal.

Practice Implications

We need to ensure that specifically designed technologies for our target populations are fit for purpose, efficacious, acceptable to both patients and healthcare providers.

Testing and Modification of Evaporation models &amp; development of a regression model to compute pan Evaporation in Kulsi Watershed, Kamrup, Assam.
Authors: Yasmin Samima 
Published: January 2023

Abstract
Evapotranspiration constitutes one of the major components of the hydrological cycle and hence its accurate estimation is of vital importance to assess water availability and requirements. Knowing the rate of evaporation from surface water resources such as channels and reservoirs is essential for precise management of the vital resource called water. This study evaluates the performance of five evaporation estimation models viz. Dalton's Model, Penman-Monteith Model, Priestley Taylor Model, Hargreaves Model and Jensen-Haise Model to compute pan evaporation in Kulsi Watershed, Assam. These models involve the use of meteorological parameters such as temperature, solar radiation, relative humidity and wind speed. Model predicted evaporation rates were compared with observed values and considerable discrepancy in model predicted values were observed. An attempt was therefore made to analyze the causes of variation occurring between model predicted and observed evaporation data, based on which all the selected models were modified to make them useful for the region. Further, the modified models were used to predict evaporation rate and it was observed that the modified models could predict evaporation rate with a higher degree of accuracy. The study was also carried out to develop a local regression model with evaporation as the predicted variable and temperature, relative humidity, wind velocity and solar radiation as the predictor variables following multiple linear regression technique based on the data collected over the last ten (10) years. This was done to serve the purpose of a local physical basis and was carried out to study the effect of different climatological parameters on evaporation. The accuracy of estimating actual evapo-transpiration relies primarily on the ability of models to represent the physical laws governing the process and accuracy of observed meteorological data. The model estimated values were compared with the observed pan evaporation data and based on the results the models were modified suitably, to meet local requirements.
Multiple Time Servers Timed-Release Encryption Based on Shamir Secret Sharing

Published: January 2023

Abstract
Timed-release encryption (TRE) is a cryptographic primitive that can realize the data be decrypted and accessed only at a specified time in the future preset by the data sender. Currently, most TRE schemes adopt noninteractive single time server mode. However, once the single time server is attacked or corrupted, it is prone to directly threaten the TRE security application. Although there are some TRE schemes that "distribute" the single time server into multiple ones, there is a problem that they cannot resist single-point failure. For this reason, a multi-time server TRE scheme based on Shamir secret sharing and its variant scheme are proposed. In our proposed schemes, the ciphertext can be decrypted when the number of time trapdoors obtained by the data receiver exceeds or equals to the threshold. It can not only guarantee the security of data sender's identity privacy information, but also greatly improve the reliability of TRE. Security analysis shows that our schemes have data confidentiality, verifiability, anti-advance decryption and multi-time trapdoor robust decryption. Efficiency analysis shows that when choosing a reasonable threshold, the computational efficiency of our schemes is slightly improved compared with the existing multiple time servers TRE schemes.
Systemic Stress in Hunter-gatherers From the Central Pampas Dunefields (Argentina). Evaluating Linear Enamel Hypoplasia During the Holocene
Authors: Marini Narella , Flensborg Gustavo 
Published: January 2023

Abstract

This article aims to evaluate whether the socio-environmental changes observed in the Central Pampas Dunefields (Argentina) throughout the Holocene (ca. 11.700-350 cal yr BP) caused episodes of systemic stress in hunter-gatherer populations. Linear enamel hypoplasia was analyzed macroscopically with a 40X magnifying glass and oblique light in 337 teeth from 26 adult individuals recovered from 11 archaeological sites. Data were analyzed following three levels of observation: individual, tooth, and number of dental enamel lines. 42.3% of the individuals analyzed presented linear enamel hypoplasia. The lines affected males and females similarly. A higher frequency was observed in the Late Holocene (ca. 4200-350 cal yr. BP) about earlier periods. The age of growth-disruption events occurred between 2 and 6.05 years, and stress events are observed at earlier ages in the Late Holocene than in the Middle Holocene. The causes could be related to metabolic stress associated with weaning, variations in the availability of natural resources over time, development of infectious and parasitic diseases during changes in social organization strategies in the Late Holocene, and gastrointestinal diseases by water intake in poor conditions. Comparison at the level of the Pampas region indicates moderate to high values of linear enamel hypoplasia, suggesting the exposure of hunter-gatherer groups to recurrent episodes of stress during the early stages of postnatal life.

Authors: MAHENDRA ROUCHIN , Chandra Ramesh 
Published: January 2023

Abstract
Multispectral electro-optical/infrared payloads are being developed for a variety of defence and commercial system applications. Many applications depend on its ability to detect and recognize low-contrast and distant targets in a complex environment. The development of such systems necessitates the use of specialized optical filters capable of separating different spectral bands. We have designed and developed silicon-based plate beam splitter for 45-degree angle of incidence that will be used to separate the bands from visible to MWIR. This beam-splitter separates MWIR from VNIR and SWIR. The silicon beam splitter was developed using an ion-assisted e-beam evaporation technique. An average reflection of ~ 75% in visible and ~ 83% in SWIR region was measured using double beam spectrometer 1050 from M/s Perkin Elmer. An average transmission ~ 85% in the MWIR region was measured using FTIR frontier spectrometer from M/s Perkin Elmer.

Abstract
Patients with occlusion myocardial infarction (OMI) and no ST-elevation on presenting ECG are increasing in numbers. These patients have a poor prognosis and would benefit from immediate reperfusion therapy, but we currently have no accurate tools to identify them during initial triage. Herein, we report the first observational cohort study to develop machine learning models for the ECG diagnosis of OMI. Using 7,313 consecutive patients from multiple clinical sites, we derived and externally validated an intelligent model that outperformed practicing clinicians and other widely used commercial interpretation systems, significantly boosting both precision and sensitivity. Our derived OMI risk score provided superior rule-in and rule-out accuracy compared to routine care, and when combined with the clinical judgment of trained emergency personnel, this score helped correctly reclassify one in three patients with chest pain. ECG features driving our models were validated by clinical experts, providing plausible mechanistic links to myocardial injury.

Authors: Song Kyungsub , Jang Woo Sung , Park Namhee , Kim Yun Seok , Kim JaeBum 
Published: January 2023

Abstract
Background: Retrograde aortic root dissection toward the coronary ostium is uncommon, and acute myocardial ischemia is a potentially fatal condition in this situation. Repairing dissected coronary arteries to prevent myocardial malperfusion is difficult and we introduce our technique with case presentation.
Case presentation: A 52-year-old male patient was admitted for acute type A aortic dissection. Circumferential detachment of the right coronary artery (RCA) ostium was detected intraoperatively. The proximal RCA was dissected, the intimal RCA was circumferentially detached with inner intussusception, and only adventitia was partially connected to the aortic root. Instead of performing coronary artery bypass grafting surgery to the RCA, direct RCA implantation to the ascending graft was performed after repairing the dissected lumen of the proximal RCA. Cardiopulmonary bypass weaning was smooth, and no complications related to the RCA were observed.
Conclusion: Repairing dissected coronary artery at retrograde aortic root dissection is feasible option.

Published: January 2023

Abstract
This research is mainly dealt with determining the effectiveness of base isolation in multiple degree of freedom systems (MDOF) of different fundamental natural time periods (FNTP). Base isolation devices avert the detrimental ground shaking to maximum extends and mitigates the lateral forces caused by earthquakes. In this research, it is intended to study about under what circumstances base isolation system will be effective in reducing the lateral forces caused by earthquakes. Every MDOF system will be having its own FNTP with respect to its mass, stiffness and damping matrices. In order to determine the effectiveness of base isolation, five number of five-story buildings of different FNTP, i.e., 0.4 sec, 0.8 sec, 1.2 sec, 1.6 sec and 2.0 sec had been selected. Different FNTP were obtained by maintaining constant mass as well as damping matrices while changing stiffness matrix for each building. Subsequently, comparison was made between the structural responses of buildings with and without providing base isolation. Finally, it was found out that a building of lower FNTP was performing well when it was provided with base isolation.

Published: January 2023

Abstract
Plant disease can cause reduce quality and quantity of agriculture crops. In some countries farmers spend considerable time to consult with plant protection, while the time is an important factor to controlling of disease. Due to the fact that Powdery Mildew and Anthracnose fungal diseases cause the most damage in cucumber greenhouses, in this study, by presenting a non-destructive method based on image processing technique and artificial neural network, these two types of fungal diseases have been diagnosed. The steps related to the implementation of the proposed method are divided into three parts: segmentation, separation of damaged parts from the leaf and classification of the disease type class. After color and texture features were extracted from cucumber leaf samples, a multilayer perceptron neural network with error post-diffusion learning algorithm was used to separate different classes of images. Network input is the average of the main color components (R, G, B) of the images and the output is zero as a healthy leaf, number one as Powdery Mildew and number two as Anthracnose. The structure of this network was 24-3-4-3, which uses the tansig transfer function for the hidden and output layer, and among the educational functions. So back propagation (BP) algorithm in neural network by using lovenerg marquart (LM) function training has been successfully to diagnosis and classifies plant diseases in 6 second with 99.95% accuracy.

Published: January 2023

Abstract
N-doped multi-shelled Ru-Co/Co3O4 graphene coated nano-spheres have been synthesized from metal organic frameworks (MOFs) using hydrothermal method. Annealing temperature of 250oC, 310oC, 380oC, 450oC and 530oC at heating rate of 2oC/min in presence of melamine under N2 atmosphere have resulted into multiple shell structured nano-spheres. Annealing temperature becomes the controlling factor in number of shell formation inside the nano-spherical materials and in better incorporation of nitrogen into the spherical structure. The present research work has shown the formation of quintupled shell structured nano-sphere at 530oC with greatest incorporation of nitrogen. Number of shell and nitrogen incorporation becomes the pivotal point of these materials’ electrocatalytic performance in water splitting. Therefore, quintupled shell structured nanospheres have shown remarkable electrocatalytic performance during water splitting with highest current density at lowest over-potential value in hydrogen and oxygen evolution reactions (HER and OER) under acidic media. Similarly, electrocatalytic activity gradually diminishes with decrease in the shell numbers inside nano-spheres.

Published: January 2023

Abstract
This work is focused on the effects of kiwi zinc oxide (ZnO) nanoparticles that are prepared through green synthesis, on Staphylococcus aureus isolated from different cosmetic tools. Zinc acetate was utilized ions while kiwi peels extract was used as a reducing agent. The formation of zinc oxide nanoparticles (ZnO NPs) was confirmed by the change of the color from green to brown and the UV-visible spectral analysis which revealed a strong surface plasmon. In addition, transmission electron microscope, and Atomic Force Microscopy (AFM) characterization showed that ZnO NPs has a spherical shape with a mean diameter of 19.76 nm. Forty swab samples were taken from different cosmetics tools and were cultured. S. aureus was identified by the biochemical and molecular identification methods. Results showed powder sponge recorded the highest, among the cosmetic tools, that harbors staphylococci bacteria. The Minimum Inhibitory Concentration (MIC) with different concentrations (128, 64, 32 and 16) mg/ml of ZnO NPs, was studied. A well diffusion test was performed to detect S. aureus sensitivity towards Kiwi ZnO nanoparticles and the result showed that the lowest inhibition zone (of 17 mm) was produced by (16mg/ml) concentration and the greatest zone (of 27 mm) was recorded by (128mg/ml) concentration.

Published: January 2023

Abstract
Purpose
To investigate the accuracy of intraocular lens prediction formulas in highly myopic eyes that have been implanted with a negative-powered intraocular lens.
Methods
A retrospective review of 19 eyes that underwent uneventful phacoemulsification with negative power Acrysof MA60MA. A multiple comparison analysis test was used to compare three different set of formulas:(a) third generation formulas (SRK-T, Haigis, Hoffer Q and Holladay 1) with optimized constants, (b) third generation formulas with axial length (AL) adjustment and (c) fourth generation formulas (Barrett Universal II). Preoperative, intraoperative, and postoperative data were collected for analysis.
Results
Mean preoperative spherical equivalent was − 22.63D with a mean AL of 32.61mm. Among the group of third generation formulas with optimised constants, Haigis had the lowest mean numerical error (MNE) and mean absolute error (MAE) of 0.070D and 0.581D respectively. A significant difference was found compared to Holladay 1 and Hoffer Q formula(p < 0.05). Haigis Formula performed better among third generation formulas with AL adjustment as well (MNE − 0.658 D and MAE 0.354 D). But no statistical difference was found with SRK-T, Hoffer Q and Holladay1 with AL adjustment. Barrett Universal II Formula had MNE of 0.026 D, MAE 0.416 D. Paired t-test showed that Haigis Formula with AL adjustment and Barrett Universal II Formula performed statistically better than Haigis formula with optimized constant.
Conclusion
Our study recommends using Barrett Universal II formula or third generation formulas with AL adjustment in highly myopic patients that require a negative MA60MA IOL implantation for cataract surgery.
Time to interval cholecystectomy and associated outcomes in older people with mild gallstone pancreatitis
Authors: BLUNDELL JIAN D , GANDY ROBERT C , CLOSE JACQUELINE CT , HARVEY LARA A 
Published: January 2023

Abstract
Background:
Cholecystectomy on index admission for mild gallstone pancreatitis (GSP) is recommended, although not always feasible.1 This study examined rates and outcomes of older people who underwent interval (delayed) cholecystectomy at increasing time points.
Methods:
Hospitalisation and death data were linked for individuals aged ≥ 50 years admitted to hospital in New South Wales, Australia with mild GSP between 2008–2018. Primary outcome was interval cholecystectomy timing. Secondary outcomes included mortality, emergency readmission for gallstone-related disease (GSRD) (28 and 180-day), and length of stay (LOS) (index admission and total six-month GSRD).
Results:
3,003 patients underwent interval cholecystectomy: 861 (28.6%) at 1–30, 1,221 (40.7%) at 31–90 and 921 (30.7%) at 91–365 days from index admission. There was no difference in 365-day mortality between groups. Longer delay to cholecystectomy was associated with increased 180-day emergency GSRD readmission (17.5% vs 15.8% vs 19.9%, p < 0.001) and total six-month LOS (5.9 vs 8.4 vs 8.3, p < 0.001). Endoscopic retrograde cholangiopancreatography (ERCP) was increasingly required with cholecystectomy delay (14.5% vs 16.9% vs 20.4%, p < 0.001), as were open cholecystectomy procedures (4.8% vs 7.6% vs 11.3%, p < 0.001). Extended delay was proportionally more likely in patients of lower socioeconomic status, regional/rural backgrounds or who presented to a low volume or non-tertiary hospital (p < 0.001).
Conclusion:
Delay to interval cholecystectomy results in increased rates of emergency readmission, overall LOS, risks of conversion to open surgery and need for ERCP. Index admission cholecystectomy is still recommended, however when not possible, interval cholecystectomy should be performed within 30 days to minimise patient risk and healthcare burden.
