Authors: Rasheed R  , Ahmed A
Published: May 2023

Introduction: Due to the high prevalence of Fe deficiency in human populations, especially in developing nations, increasing Fe concentration in cereal crops is a major global challenge. Biofortification of cereals such as wheat with Fe is an attractive approach that can significantly compensate for Fe malnutritionand human health issues. Under nutrient imbalance circumstances, bio-fertilizers have been reported to play a vital role in plant development. Aims/Objectives: The current study was designed to evaluate the potential of PGPR to be used as bio-fertilizers and appraised their capability to enhance plant growth, quality and nutrient content, in combination with Fe treatment to combat malnutrition. Methodology: PGPR were screened for auxin producing ability and biochemically characterized for various growth promoting attributes. Fe in various combinations with PGPR was applied in soil and as foliar spray to the plants. Various growth and biochemical parameters were recorded. Wheat leaves were subjected to atomic absorption spectrometric (AAS) analysis. Results: Five bacteria with maximum auxin production potential were selected as bio-fertilizers. 36% improvement in fresh weight was recorded in Pseudomonas sp.(FS2) inoculations in the presence of 100µg/ml Fe under laboratory conditions, whereas, in wire house setup, plants supplemented with Jeotgalicoccus aerolatus (Tr3)exhibitedremarkable elevation in sugar content 298% with 100µg/ml foliar application of Fe. Data obtained from AAS showed that plants treated with Burkholderia cepacia (FS1) and Proteus mirabilis (Pc3) exhibited 2.17 and 2.28 ppm Fe content as a result of soil and foliar spray of 200µg/ml Fe respectively. Conclusion: Foliar application of Fe along with bio-fertilizers has proven to be a practical approach to improve grain quality and Fe content. Hence, biofortification of cereal crops with micronutrients and bio-fertilizers can assure a sustainable, eco-friendly and cost-effective solution to cure malnutrition and food security in developing countries.

Published: May 2023

"Across the Color Line" is part of a larger digital project, The American Soldier in World War II. The project has made accessible sixty-five thousand pages of uncensored handwritten commentaries composed by US service members, along with quantitative datasets produced by a novel interdisciplinary US Army research branch. This small organization of leading psychologists and social scientists was tasked with analyzing and reporting on soldier morale, including the rank-and-file effects of segregation and relations between the races. This article showcases initial findings derived from a cross-sectional survey of Black and White soldiers administered in February and March of 1943, only months before race rebellions erupted in Detroit, Los Angeles, Harlem, and elsewhere over the country's maintenance of Jim Crow while the US and its allies were at war to save democracy. Text correlation networks reveal in striking visual detail the effects of segregation on the experiences, habits, and opinions of both White and Black US citizen-soldiers, individually and collectively. Network-based visualizations are particularly effective at revealing the inverted epistemology of American racial thought and of W.E.B. Du Bois's popular characterization of Black America's "double consciousness," or "twoness."

The danger of lead in paint that is coated on the human body, silver can enter through the skin and will interact with proteins, DNA, RNA and oxidative stress. Formation of Reactive Oxygen Species (ROS) by lead can cause oxidative stress and is characterized by an increase in the enzymes catalase, malondialdehyde (MDA) and Oxidized glutathione (GSSG). The aim of this study was to analyze blood lead levels against Malondealdehyde (MDA) in silver humans in Semarang City. This study used an observational analytic study with a cross sectional approach to analyze the effect of lead levels on Malondialdehyde levels in silver humans in Semarang City using a t test to see differences in results based on length of work, length of exposure and age on lead levels, and the effect of lead on MDA. The results showed that from 20 human samples, the lowest lead level was 23.9 g/dl and the highest was 61.9 g/dl with an average blood lead level of 37.3 g/dl with an average blood lead level of 37.3 g/dl, and the lowest MDA level was 0.4 mg/L and the highest level is 1.74 mg/L with an average of 1.2 mg/L. Based on the data obtained from the t test, it shows a significant value (P-Value) of 0.610 which means 0.05, this indicates that the decision taken is to reject H1 which means that there is no effect between the results of lead levels on the results of MDA levels.

Published: May 2023

Background:

The Cognitive role of untreated type 2 diabetes mellitus (T2DM) has been less well substantiated.

Objective:

We sought to explore the prospective association of T2DM and untreated T2DM with cognitive function among middle-aged and older Chinese adults.

Methods:

Data of 7,230 participants without baseline brain damage/mental retardation, or memory-related diseases in China Health and Retirement Longitudinal Study (CHARLS) from 2011– 2012 to 2015, were analyzed. Fasting plasma glucose and self-reported information on T2DM diagnosis and treatment were assessed. Participants were categorized into normoglycemia, impaired fasting glucose (IFG), and T2DM (including untreated and treated T2DM) groups. Episodic memory and executive function were assessed by modified Telephone Interview for Cognitive Status every two years. We used generalized estimating equation model to examine the association of baseline T2DM status with cognitive function in succeedingyears.

Results:

Compared to those with normoglycemia, T2DM was associated with worse overall cognitive function after controlling for demographic variables, lifestyles, follow-up time, major clinical factors, and baseline cognitive function, although the associations were statistically non-significant ( β= –0.19, 95% CI: –0.39, 0.00). However, a significant association was mainly observed for those with untreated T2DM ( β= –0.26, 95% CI: –0.47, –0.04), especially in the domain of executive function ( β= –0.19, 95% CI: –0.35, –0.03). In general, IFG and treated T2DM individuals had similar levels of cognitive function with normoglycemia participants.

Conclusion:

Our findings supported a detrimental role of untreated T2DM on cognitive function among middle-aged and older adults. Screening and early treatment for T2DM are warranted for maintaining better cognitive function in later life.

Published: May 2023

Background: Resistant hypertension (RH) is a major risk factor for stroke, cognitive decline, and dementia. Sleep quality is increasingly suggested to play an important role linking RH to cognitive outcomes, although the mechanisms linking sleep quality to poor cognitive function have yet to be fully delineated. Objective: To delineate biobehavioral mechanisms linking sleep quality, metabolic function, and cognitive function among 140 overweight/obese adults with RH in the TRIUMPH clinical trial. Methods: Sleep quality was indexed using actigraphy measures of sleep quality and sleep fragmentation, as well as self-reported sleep quality from the Pittsburgh Sleep Quality Index (PSQI). Cognitive function was assessed using a 45-minute battery assessing executive function, processing speed, and memory. Participants were randomized to a cardiac rehabilitation-based lifestyle program (C-LIFE) or a standardized education and physician advice condition (SEPA) for 4 months. Results: Better sleep quality at baseline was associated with better executive function (B = 0.18 p = 0.027), as well as greater fitness (B = 0.27, p = 0.007) and lower HBA1c (B = –0.25, p = 0.010). Cross-sectional analyses revealed that the sleep quality executive function association was mediated by HBA1c (B = 0.71 [0.05, 2.05]). C-LIFE improved sleep quality (–1.1 [–1.5, –0.6] versus+–0.1 [–0.8, 0.7]) and actigraphy steps (+922 [529, 1316] versus+56 [–548, 661]), with actigraphy mediating improvements in executive function (B = 0.40 [0.02, 1.07]). Conclusion: Better metabolic function and improved physical activity patterns levels play important roles linking sleep quality and executive function in RH.
If Midlife Brain Injury Is a Risk Factor for Alzheimer’s Disease and Related Dementias, What Is the Neuropathologic Mechanism?
Authors: White Lon R.
Published: May 2023

While we know that brain injuries related to sport and military activities sometimes lead to cognitive impairment or early onset dementia, it is unclear if and how they might influence the development of Alzheimer’s Disease and Related Dementias (ADRD). Published analytic conclusions have been mixed. Two reports in the Journal of Alzheimer’s Disease reach the same answer: a history of brain injury appears to be a risk factor for generalized brain atrophy, which would likely increase vulnerability to the subsequent development of any variety of ADRD, or to dementia directly attributable to reduced brain mass.

Authors: Sun Shuwan , Bian Weixin , Xie Dong , Xu Deqin , Huang Yi
Published: May 2023

With the development of wireless communication technology and the rapid increase of user data, multi-server key agreement authentication scheme has been widely used. In order to protect users’ privacy and legitimate rights, a two-factor multi-server authentication scheme based on device PUF and users’ biometrics is proposed. The users’ biometrics are combined with the physical characteristics of the Physically Unclonable Functions (PUF) as authentication factors, which not only ensures the security of the scheme, but it also is user-friendly without a password. The proposed scheme can be applied to telemedicine, smart home, Internet of Vehicles and other fields to achieve mutual authentication and key agreement between users and servers. In order to prove the security of the proposed scheme, the widely accepted ROR model and BAN logic are used for formal security analysis. The scheme can effectively resist various security attacks, and the comparison with existing schemes shows that it has better performance in terms of communication cost and computational complexity.
A novel optimization control of gas turbine based on a hybrid method using the BELBIC and adaptive multi input multi output feedback control
Authors: Li Lin
Published: May 2023

In recent years, the use of Gas Turbines (GTs) to generate electricity has grown exponentially. Therefore, for the optimal performance of gas power plants, a lot of research has been done on modeling different parts of GTs, estimating model parameters, and controlling them. But most of the available methods are not accurate enough, like most linear methods, or are model-based, which require an accurate model of the system (like most nonlinear methods), or there is a constant need to adjust the controller parameters. To address these shortcomings, this study uses a new hybrid method including the brain emotional learning-based intelligent controller, the nonlinear multivariate method in the form of feedback linearization, and an adaptive control method of mode predictive reference model used to quickly control the GT. The Rowen model is used to simulate the nonlinear model of the GT. Owing to the influence of exhaust temperature on the speed of GT and the multivariate system model, nonlinear multivariate controller design is considered. First, the adaptive control method of the state-predictive reference model for a multi-output multi-input system, in general, is presented, and then, the proposed method for a GT with real dynamic values is implemented. The simulation results show the ability of the proposed controller to control the GT. In order to prove the efficiency of the proposed method, the obtained results are compared with the PID industrial controller method and the classical reference model method.

Published: May 2023

By the reaction of a mixture of isomers (2.4-2.6) of toluene diisocyanate with aliphatic, individual or oligomeric diols (such as polyoxypropylene glycols of different molecular weight) in cyclohexanone, oligodiurethane diisocyanates with the diol component of different nature and length in their structure are synthesized in the first stage. In the second stage, the synthesized oligodiurethane diisocyanates were blocked by monofunctional aliphatic alcohols of normal structure with different lengths of fatty radical. The structure of the latter is confirmed by the absence of absorption bands characteristic of free –NCO groups in the IR spectra. Both series of isolated oligodiureta diisocyanates and oligotetraurethanes are characterized by refractive index and Ubellode drop temperature, molecular weights, content of free –NCO groups, and IR spectra. They are well soluble in esters, ethers, chlorinated and aromatic hydrocarbons, ketones, and aprotic solvents; they are poorly soluble in aliphatic hydrocarbons. The presence in the structure of such compounds of polar urethane groups simultaneously with relatively high molecular weight suggests that they will be useful not only as plasticizers, but also as modifiers of the properties of polymers and composite materials.

On an energy basis, without involving the apparatus of dynamics of

structures, an analytical solution of the problem was obtained to determine the dynamic

additional loads in complexly stressed reinforced concrete elements of multi-storey frames

in a transcendental state caused by special emergency effects. The stress state, crack

patterns and fracture patterns in the crossbars of the considered frame structures are

determined by the complex stress state of the frame elements caused by the combined action

of torsional and bending moments. The assessment of the bearing capacity of such

structures was carried out by the diagram method based on the use of energy ratios in the

structural elements before and after a special impact, which makes it possible to determine

the maximum dynamic deformations, curvatures and forces in the first half-wave of

vibrations using the results of nonlinear static calculations according to the primary and

secondary design schemes.

У часи післявоєнного відновлення, економічні успіхи України в значній мірі будуть залежить від використання нею водного транспорту, який сприятиме інтенсифікації її торгівлі з рештою світу. Особливо важливою для розвитку водного транспорту України є роль людського капіталу. Нестача висококваліфікованих моряків торгового флоту може створити певні виклики на шляху підвищення конкурентоспроможності водного транспорту України у період післявоєнного відновлення. Мета роботи полягає у виявленні залежності рентабельності діяльності підприємств водного транспорту України від середньооблікової кількості штатних працівників, які працюють на українські судноплавні компанії, повністю забезпечують потребу у людських ресурсах для перевезення вантажів водними шляхами та ходять під прапором України. Для вирішення поставлених завдань використовувалися такі методи: системно-структурний, абстрактно-логічний аналіз і групування – при дослідженні структури особового складу моряків-громадян України; економіко-математичного моделювання – при побудові залежності рентабельності діяльності підприємств водного транспорту України від середньооблікової кількості штатних працівників; розрахунково-аналітичний – при аналізі динаміки середньомісячної заробітної, руху персоналу на підприємствах водного транспорту та при проведенні перевірки якості побудованої нами математичної моделі. Досліджено структуру особового складу моряків-громадян України та динаміку середньооблікової кількісті штатних працівників, зайнятих на підприємствах водного транспорту України. Проведено аналіз динаміки середньомісячної заробітної плати штатних працівників, зайнятих на підприємствах водного транспорту України та рух персоналу на підприємствах водного транспорту України. Побудовано залежність рентабельності діяльності підприємств водного транспорту України від середньооблікової кількості штатних працівників, зайнятих на них в Україні. Вказана залежність була записана математично та представлена графічно. Нами було досліджено щільність зв’язку між рентабельністю діяльності підприємств водного транспорту України і середньообліковою кількістю штатних працівників, зайнятих на них. Для перевірки якості побудованої моделі нами було розраховано ключові показники та проведено ряд спеціальних тестів. З метою підвищення конкурентного потенціалу водного транспорту України в статті розроблено рекомендації щодо збільшення кількості моряків, які працюють на українські судноплавні компанії, повністю забезпечують потребу у людських ресурсах для перевезення вантажів водними шляхами та ходять під прапором України.

Authors: Gotama Bangkit , Addina Khalisa , Ananda Nur Afrie Rizqie
Published: May 2023

White pepper is one of the staple spices of East Kalimantan. In order to boost the competitiveness of white pepper commodities, it is necessary to raise the added value of the commodity by transforming it into high-value goods, such as white pepper oil. This research intends to evaluate the production of local (LPL) white pepper oil (MLP) with commercial white pepper oil (LPK) using different extraction techniques (microwave-assisted hydro distillation, MAHD; and ultrasonic following hydro distillation, US-HD). This experiment also evaluated the effect of extraction factors on oil yield, including microwave power on MAHD, ultrasonic wave power on US-HD, sonication duration on US-HD, and solvent volume. A comparison of the energy usage of both approaches was also conducted in order to identify the most effective approach. The MAHD and US-HD techniques were used to extract 80 grams of dry white pepper powder mixed with aquadest for 90 and 180 minutes, respectively. Specifically for US-HD, the combination of raw materials was sonicated for 3-5 minutes prior to extraction utilizing the HD method. In both MAHD and US-HD, LPK includes more MLP than LPL, according to experimental findings. MLP yield may be increased by the addition of solvent, wave power (micro and ultrasonic), and sonication time. Based on its efficiency and energy consumption, the US-HD approach is superior to the MAHD.

This study aims to determine the absorption of nutrients N, P, total chlorophyll, and combination interactions due to the application of tofu liquid waste and growing media to long beans. The study used a factorial randomized block design (RBD) with 3 replications. Factor I of tofu liquid waste treatment (T) consisted of 3 levels, namely: T0 (0 ml), T1 (150 ml), T2 (300 ml ), and Factor II , Growing Media (M) consisted of 3 planting media, namely M1 (compost of cow dung + rice husk charcoal), M2 (compost of cow dung + cocopeat), and M3 (compost of cow dung + chopped fern). The observed variables included nutrient uptake of N-Total, P, and total chlorophyll content. The results showed that the treatment of tofu liquid waste had a very significant effect on N-Total and P nutrient uptake, namely 150 ml (T1) and the administration of 300 ml (T2) had a very significant effect on total chlorophyll content. The growing media had a very significant effect on nutrient uptake of N, P, and total chlorophyll content in the M3 treatment( cow manure compost + chopped fern). There was no interaction between tofu liquid waste and planting media for all observed variables

The article considers the peculiarities of implementation of performance indicators of the sales department at construction enterprises. Achievement of the planned indicators is possible through effective resource management based on information about the company's economic and operational activities, analysis and prevention of possible deviations from the plan. In addition, these indicators should be fully consistent with the fundamental strategic goals of the entire organisation. In this regard, special attention is paid to setting achievable values that will satisfy both the fundamental aspirations of the owners to increase profits and the real market and organisational capabilities of the construction industry. The KPI system is used as the main tool for regulating this task, due to its ability to identify and control specific, measurable actions. The position of the KPI system in the overall structure of the sales department has been determined. The key performance indicators of a sales manager in the context of his activities at a manufacturing enterprise with specifics of work in the construction materials market are researched. An analysis of the results of the commercial department's activities in terms of meeting the planned indicators is carried out. It has been found that when implementing KPIs, the motivation system becomes clear and transparent, since planned and actual values are recorded. The applied strategy reveals its weaknesses and the necessary principles of employee motivation in relation to the set goals. The internal factors of influence on the performance of the sales department are proposed, which improve the internal climate and create favourable conditions for motivation and initiative of employees. It is proved that the use of KPI performance indicators allows identifying and adjusting specific tasks necessary to achieve the planned goals, more efficiently managing available resources in key areas of activity, and controlling the economic and operational activities of the company.
