Authors: Long Kelvin F. 
Published: May 2024

In this paper, we present updated calculations for the SunVoyager probe, a spacecraft conceptual design for a mission to the outer solar heliosphere to a distance of 500–1000 AU, in a trip time of [Formula: see text] traveling at speeds of [Formula: see text]. The spacecraft is innovative, in that it uses an inertial confinement fusion propulsion engine driving a 5.76-mg pellet filled with [Formula: see text] fuel detonated at 10-Hz pulse frequency, augmented with [Formula: see text] expellant propellant for enhanced mass flow rate. The spacecraft is designed to carry a 100-ton payload to include large optical telescopes for long-range imaging of nearby exoplanets. This paper is a follow-up to the earlier one that scoped out the design space, and here we give details on a more refined design configuration, in addition to calculations relating to the pellet ignition design and laser driver with 43.5 MJ delivered to the target. We also describe the power cycle with a jet efficiency of 37.8%, for a jet power of 2.67 GW and a specific power of [Formula: see text].

Published: May 2024

Wśród najważniejszych czynników które mają istotny wpływ na stan zdrowia, a także długość życia należy wymienić sprawność fizyczną (AF). Sprawność fizyczna to jeden z głównych składników zdrowego stylu życia. Istnieje powszechne przekonanie, że sprawność fizyczna jest jedną z ważniejszych kategorii warunkujących prawidłowe funkcjonowanie ludzkiego organizmu. Po piątej dekadzie życia odczuwalne są jego trudy. Obniża się wydolność fizyczna, stan psychiczny. Dokuczliwe są trudności z koncentracją oraz przyswajaniem nowych informacji. Dlatego należy dbać o kondycję fizyczną i psychiczną, ponieważ przedłuża to okres sprawności. Prowadzenie aktywnego stylu życia wiąże się bowiem z wieloma korzyściami. Korzyści z podejmowania aktywności fizycznej są oczywiste. Systematyczna aktywność fizyczna jest bardzo silnym biologicznym stymulatorem i należy do głównych determinant zdrowia fizycznego i psychicznego człowieka. Jej optymalny poziom stymuluje rozwój, zabezpiecza potrzeby ruchowe, wzmacnia wydolność serca, poprawia elastyczność mięśni i stawów, wzmacnia mięśnie i kości. Aktywność fizyczna wiąże się oczywiście z bardzo zróżnicowanym wydatkiem energetycznym, w zależności od intensywności ruchu/wysiłku fizycznego, jego czasu trwania, temperatury otoczenia czy masy ciała osoby wykonującej wysiłek fizyczny. Poprzez sprawność fizyczną osób starszych określa się zdolności motoryczne całego ciała, a także jego samodzielność w wykonywaniu różnych aktywności. Udowodniono, że osoby sprawne fizycznie, w porównaniu do osób mało aktywnych, cieszą się lepszym samopoczuciem, rzadziej odczuwają dolegliwości psychiczne lub fizyczne, takie jak obniżony nastrój czy bóle głowy.
Sprawność fizyczna seniora jest zależna np. od jego trybu życia i aktywności fizycznej, jaką podejmował we wcześniejszych fazach życia. Nawet u osób z obniżoną wydolnością można ją podwyższyć dzięki uprawianiu turystyki, która skłania do aktywności ruchowej. Poprzez turystykę ludzie starsi mogą zrealizować swoje pasje i marzenia, poszerzyć system wartości, opierając go na doznaniach kulturalnych i estetycznych. Mogą urozmaicać swoje życie, odrywając się od codziennej rutyny, a często i samotności. Turystyka pozwala zdobyć nowe wiadomości o świecie, dzięki czemu człowiek rozwija się i posiada większą świadomość otoczenia, wzmacnia swoje poczucie wartości oraz pewności siebie. Człowiek starszy dzięki aktywności turystycznej wolniej się starzeje i dłużej pozostaje sprawny. Można powiedzieć, iż jest to pewna forma terapii, która aktywizuje myślenie, ułatwia nawiązywanie kontaktów interpersonalnych, zapobiega samotności. Turystyka powinna być stałym elementem zdrowego i aktywnego stylu życia ludzi starszych.
Mesenchymal cells as the biological modifiers for stimulation and regulation of cellular and molecular healing and regeneration
Authors: Sachdeva Shivani , Saluja Harish 
Published: May 2024

Biologic modifiers are materials or proteins and factors that have the potential to alter the host tissue so as to stimulate or regulate the wound healing process. Classic examples of biologic modifiers are growth factors. Bioengineered materials are widely utilized due to their biocompatibility and degradability, as well as their moisturizing and antibacterial properties. One field of their application in medicine is to treat wounds by promoting tissue regeneration and improving wound healing. In addition to creating a physical and chemical barrier against primary infection, the mechanical stability of the porous structure of biomaterials provides an extracellular matrix (ECM)-like niche for cells. Growth factors are polypeptide molecules that control the growth, differentiation, and metabolism of cells during each of the three phases of wound healing. They are present throughout the body in only minute concentrations yet exert a powerful local influence on wound repair. They interact with specific receptors in the cell surface, leading to specific responses determined by the receptor-mediated signal transduction pathways within the target cells. Growth factors (GFs) and cytokines, which are secreted by the cells, are essential parts of the complex process of tissue regeneration and wound healing.
A Rapid and Robust DNA Extraction Method for PCR-Based Diagnosis of V. cholerae

Published: May 2024

Cholera, caused by _V. cholerae_, needs rapid diagnosis because of its threat for rapid spread. Recent molecular diagnosis by PCR assay is more advantageous than the conventional methods. The bottleneck in PCR diagnosis lies in the delay in template DNA extraction of _V. cholerae_, which is the basic requirement. This study describes a simple, less expensive, and rapid template DNA extraction method to lessen the total time for PCR diagnosis of _V. cholerae._ To obtain template DNA, our method involves boiling of _V. cholerae_ suspension in distilled water (takes 18-24 hours) instead of boiling the suspension in broth medium, which is a lengthy process (takes 72 hours). The validation of our template DNA was conducted using 40 _V. cholerae_ O1 strains that were confirmed previously, and its usefulness was checked on 20 clinical strains of _V. cholerae_ O1 isolated from acute diarrhea patients; results were compared with those of conventional template DNA. The analysis of our template DNA in simplex and quadruplex PCR assays revealed the presence of _ctxA_, _tcpA _(El Tor), _rfb _(O1), _ToxR_, _ctxB_, _zot_, _ace,rst _, and _OmpW _genes in _V. cholerae _O1. The comparison of the results of PCR assays using the template DNA from both sources showed equal results and matched correctly. The sensitivity of our template DNA was 1.5x103 CFU per assay. Our template DNA extraction method is simple, less expensive, and rapid, and it can be employed for early diagnosis of _V. cholerae_ during outbreaks, in research laboratories, and in hospital setups where infrastructures are available.

Authors: Safarida Nanda , Lili Irawati  , Safwan Kamal  
Published: May 2024

Purpose: This study aims to determine the effect of firm size, leverage, managerial ownership, and profitability on earning management in a convenience goods company, PT. Tiga Pilar Sejahtera Food Tbk, wich is listed on the Indonesian stock exchange under the name AISA.
Method: Secondary data are collected through the company’s financial statement from 2006 to 2020. The data were collected from the Indonesian Capital Market Directory (ICMD) and the Indonesian stock exchange websites. The quantitative approach was used to analyze the data. Then, the data were regressed by Ordinary Least Square estimation using Eview 12 software.
Findings: Results revealed that firm size, managerial ownership, and profitability have no significance influence on earning management. However, leverage partially has a negative and significant effect on the earnings management. Meanwhile, firm size, leverage, managerial ownership, and profitability simultaneously influence earnings management of PT. Tiga Pilar Sejahtera Food Tbk significantly from 2006 to 2020 period.
Research limitation: This research only uses some of the determinants of earnings management from many other factors that also have a contribution such as institutional ownership, board of commissioners, auditor reputation, etc. In addition, the use of several research objects in the form of companies engaged in the same business sector is also recommended for further research in order to obtain a more comprehensive and representative view.
Practical Implication: This research has implications for the company's management considerations in making decisions to carry out earnings management. This form of intervention is ideal as long as it is carried out in accordance with accounting principles. This must be ensured so that the company's economic picture remains visible and risk management can still be carried out.

Published: May 2024

Objective: To determine the linear physical dimensions of dried Mexican cocoa beans to estimate their geometric properties and differentiate them through a principal component analysis.
Design/Methodology/Approach: For the research, 51 dry samples of cocoa beans (Theobroma cacao L.) were collected from three producer states in Mexico. The physical properties of cocoa beans were determined based on their linear dimensions: length, width, thickness, geometric diameter, sphericity, volume, and shape factor. Moisture, average weight, and ether extract were also determined.
Results: The results revealed the relation between linear and geometric properties, particularly the fact that bean weight is significant (p<0.001) regarding all the properties evaluated, except moisture. Said relation explained 98.8% of the total variation in the first two components observed in the cocoa samples from the three states (Tabasco, Chiapas, and Oaxaca). Average bean weight, sphericity, and volume contributed the most to the total variation.
Findings/Conclusions: The only quantitative variable that showed significance was bean weight. The other measurements—length, width, and thickness—did not. However, there was significance when coupling the measurements in the expressions of surface area and volume.

The present study attempted an empirical investigation to the marital adjustment and suicidal ideation of adulthood. In order to collect data, participants were selected purposively; a total 108 respondents were selected. Out of these 108 respondents, 54 were of single family and 54 were of joint family. In the 54 single families, 27 were of rural areas and 27 were of urban areas. And in the 54 joint families, 27 were of rural areas and 27 were of urban areas. Again, each group consisted of 9 early adulthood, 9 middle adulthood and 9 late adulthood. Their age ranges were from 17 to 60 above years. The Bangla version of "Dyadic Adjustment Scale (DAS) (Ilyas 2001)" and "Suicidal ideation scale (Uddin and Hossain 2007)" were used to measure marital adjustment and suicidal ideation. The data were analyzed using mean, standard deviation t-value, one- way analysis of variance (ANOVA) and Pearson product moment correlation. The findings of the present study showed that mean of marital adjustment of late adulthood shows more marital adjustment than middle and early adulthood (F=68.98,df=2,p< 0.00); mean of marital adjustment of joint family was more than single family (F =14.24, df =1, p .< 0.00); mean of marital adjustment of rural areas was more than the urban areas (F = 12.23, df = 1, p < 0.00). On the other hand, early adulthood was more suicidal ideation than middle and late adulthood (F·=. 19.49, df =2, ·p <0.00); single-family was more suicidal ideation than joint family (F = 6.08, df = l, p <0.01); but residence had no significant on suicidal ideation. Result also 'showed negative correlation (r= - 0..32, p<0.001 ) between marital adjustment and suicidal ideation of adults.
