Buckling upon Inflation in Soft Porous Nonlinear Geometric (SPoNGe) Metamaterials
Authors: Tubaldi Eleonora , Barvenik Kieran , Bonthron Michael , Jones Anthony
Published: September 2024

Cellular metamaterials represent unique platforms to manipulate structure property relationships and enhance mechanical responses. While their unconventional behaviors have traditionally been obtained via pattern-transformations under compressive loading or deflation, we theoretically investigate and experimentally realize a new class of soft porous metamaterials that undergo buckling
instability upon inflation, unlocking superior programming and sequencing capabilities for soft intelligent machines. Our soft porous nonlinear geometric (SPoNGe) metamaterial reimagines the traditional rubber slab with periodic holes by incorporating a single internal pressure cavity. This novel structure, actuated via a single internal positive pressure, can be engineered to exhibit global short-wavelength buckling modes with controllable circumferential lobe count of the cylindrical pores. First, we experimentally demonstrate the programmable post-buckling behavior by tuning the geometric parameters. Then, with a combination of analytical and numerical methods, we accurately predict the critical buckling pressure and pattern reconfiguration of the cellular metamaterial. By enabling different pattern rearrangements of the collapsing pores, we achieve a new actuation mechanism to suddenly reconfigure the global structure, selectively grasp slender objects, and operate multiple fluid channels with a single input.

Authors:   Anuradha Navnath Karale1,,   Bhavna Nigam2,   Indra Jeet Chaudhary1*
Published: September 2024

The world's food problem is partly caused by the enormous hurdles that the growing global population presents to agricultural output. Increased yield losses are caused by a number of stressors, including bacteria, fungus, salt, ozone, UV-B radiation, drought, and metal toxicity. Agricultural management uses a variety of techniques targeted at reducing yield loss and environmental impact to address these problems. In order to increase crop yields, nanoparticles are used in the creation of nano fertilizers, nano insecticides, and nano fungicides. Therefore, present study conducted to assess effectiveness of ZnO and TiO2 nanoparticle on Green gram seed germination, root length, and shoot length and fresh weight and dry weight of plants. Results demonstrated that TiO2 is more effective in seed germination than ZnO nanoparticles and showed 100% rate at 48-h observation. All nanomaterials stimulated root elongation and promoted shoot growth and biomass of plants at 50 ppm concentrations. The purpose of this study is to evaluate the mechanisms and efficacy of nanoparticles in promoting seed germination. The knowledge gathered from this research is essential for the creation of eco-friendly nanotechnologies, which will ultimately help to lessen the world's food crisis. According to the study, additional field research is necessary to have a more comprehensive understanding, especially in order to completely comprehend the impacts of NPs on the growth, improvement, and health of agricultural plants.

Published: September 2024

Background:Measuring nurse work environments is essential to address the nursing shortage.
Aim: To translate and validate the “Practice Environment Scale of the Nursing Work Index” (5 items version) in Greek.
Methods: Study population included 80 nurses in Greece. We performed our study during August 2024. We employed the forward-backward method to translate and adapt the “Practice Environment Scale of the Nursing Work Index” (PES-5) in Greek language. We examined the construct validity of the PES-5 by performing confirmatory factor analysis. We examined the concurrent validity of the PES-5 using the “Quiet Quitting Scale” (QQS), the single item burnout measure, and the single item turnover intention measure. We examined the reliability of the PES-5 by calculating Cronbach’s alpha.
Results: The PES-5 showed very good psychometric properties. Our confirmatory factor analysis confirmed the one-factor structure of the PES-5. Concurrent validity of the Greek version of the PES-5 was very good. We found a statistically significant negative correlation between PES-5 and QQS (r = -0.410, p-value < 0.001), and single item turnover intention measure (r = -0.227, p-value = 0.043). We found that the PES-5 had very good reliability since Cronbach’s coefficient alpha was 0.651.
Conclusions: The Greek version of the “Practice Environment Scale of the Nursing Work Index” is a reliable and valid tool to measure the nursing practice environment.

Authors:   Assistant Professor (Law), Government Law College, Pali. And Research Scholar, Department Of Law, University Of Rajasthan., Singh Kabawat Kirtipal
Published: September 2024

Women right of reproduction is a fundamental right guaranteed by Indian constitution under article 21 i.e. right to life and personal liberty. In a recent landmark judgment of right to privacy honble supreme court has again affirmed that women has full liberty to decide whether to have or not to have their child.Bearing a child is one of the important aspects of the institution of marriage. However, there may be various instances where this task is not achieved owing to medical infertility or medical complications either of husband or wifeor of both. Although there are several instances where, in order to maintain the physical fitness certain women having no such medical complications or infertility opt for artificial procreation. Single Individuals, divorced, widows and so on and so forth may be fertile but are unable to have a child as the process of procreation requires a male and female. Homosexual individuals and couples also fall under this head. Taking into account the plight of these groups Indian Parliament has recently passed two new legislations namely, The Assisted Reproductive Technology(Regulation) Act 2021 and The Surrogacy (Regulation) Act 20211. It was not like that, before these enactments children were not born using these Assisted Reproductive Technology,but in the garb of infertility several poor women were exploited in the name of commercial surrogacy and they were left in lurch after the prospective parents refused to take the child or some citizenship issues arises and the poor overburdened family was forced to take care of that child. This lead to several court cases. This paper will deal with the new laws as well as judicial pronouncements relating to womens right of reproduction and how these laws will help in protecting the womens right of reproduction.

Authors: Teltayev Bagdat , Aitbayev Yerbol , Zhaisanbayev Azamat
Published: September 2024

In the article, under field conditions (on the lane of a city road for public transport), using modeling and traffic flow analysis methods, the formation of ruts on an asphalt concrete pavement is studied. The maximum total rut depth on the road section under consideration reaches 110 mm. 715 buses and 25 trucks pass along a separate lane of the road per day, the relative rutting impact of which is from 5.68 to 16.41 compared to the design vehicle. The design of the road pavement on the experimental section with a total thickness of 48 cm is too weak for the actual traffic flow, which was the main reason for the premature failure of the road due to unacceptable rut sizes on the asphalt concrete pavement.

Authors: Fan Yumeng , Yang Guolai
Published: September 2024

The permanent magnet eddy current brake (ECB) discussed in this paper are expected to brake a strong impact load for a large-scale machinery, and its design requirement is to brake smoothly within a given displacement limit. A design method is proposed to be able to design and calculate the based on the design requirements. According to the requirements of the brake displacement, an expected brake force can be calculated. Then, through the analysis of the permanent magnet operating point and the analysis and calculation of the design parameters, a reasonable design scheme that matches the prime design requirements can be obtained. When facing strong shock loads, in addition to satisfying braking requirements, different shock conditions can lead to different practical braking process. Making the corresponding braking process smoother can be regarded as an additional design objective, thus the design scheme obtained can be optimized in a certain range accordingly. A multi-objective optimization design of the ECB is carried out in combination with the Stackelberg game theory. After verifying the optimization results, it can be obtained that the given design and optimization methods are applicable and can satisfy the design and optimization objectives.

Published: September 2024

Background:  Cognitive impairment (CI) is frequently observed in patients with chronic kidney disease (CKD). There are many factors associated with CI in CKD patients in international studies but no study has been done previously in Pakistan on this important issue.
Objective: The objective of this study was to determine factors affecting CI in CKD patients   
Methods: This observational study was carried out in Nephrology Department of Mayo Hospital, Lahore (January 2023 to March 2023). All CKD patients, regardless of cause, were included while patients on renal replacement therapy (RRT) were excluded. The Mini-Mental State Examination (MMSE) tool was employed to evaluate cognitive function.
Results: A total of 100 patients were enrolled. The average age of the patients was 50.44±12.58 years, with diabetes mellitus (DM) being the leading cause of CKD in 53(53.0%) patients. CI was identified in 61(61.0%) patients while mild and moderate CI was found in 34 (34%) and 27 (27 %) respectively. Female gender (RR=1.40, 95%CI=1.01-193, p=0.042), low estimated glomerular filtration rate (eGFR) (RR=1.92, 95% CI=1.27-2.91, p=0.002), anemia (RR=1.23, 95% CI=1.01-1.50, p=0.003) and lower educational qualifications (RR= 3.39, 95% CI=1.65-6.94, p=<0.001) were found significant factors of CI. Increasing age was associated with increased CI severity (r=-0.110, p=0.278) while eGFR has positive correlation with CI score (r=0.271,p=0.006) .
Conclusion: CI was frequently prevalent among patients with CKD. Female gender, low eGFR, anemia and low level of education were independent predictors of CI in CKD patients. Advancing age has negative correlation while GFR has positive correlation with CI score.

Published: September 2024

Perioperative Neurocognitive (PND) disorders represent a prevalent complication
among geriatric patients, manifested in diverse forms of cognitive impairment following anesthesia
and surgical procedures. Even though the exact origin of PND disorders is still unknown,
neuroinflammation has been identified as a significant contributing factor, particularly in older
patients. Hence, this review aims to provide a deeper insight into the underlying mechanism and
associated potent therapeutic targets for the efficient management of perioperative neurocognitive
disorders. Many factors, such as PRRs, chemokine receptors, immunoglobulin superfamily
receptors, and purinergic receptors, are involved in the development and occurrence of perioperative
neurocognitive disorders to varying degrees and may be valuable biomarkers for their effective
management. Here, we present a comprehensive overview of the involvement of neuroinflammation
in PND disorders, including their onset and possible therapeutic targets. This
review would benefit future researchers in elucidating a better therapeutic approach for the management
of perioperative neurocognitive disorders. We have also briefly outlined the clinical
trials associated with Postoperative neurocognitive disorders in the last section of the review.
Altogether, this review would help the researchers investigate better therapeutics for the management
of PND disorders.

Authors: S. Sharath , Kadavigere Rajagopal , Maiya G. Arun
Published: September 2024

Background:

Diabetic peripheral neuropathy (DPN) is the prevalent microvascular
complication of diabetes mellitus (DM). 30-50% of diabetics are likely to be affected by DPN. It
significantly impacts the skeletal muscles, resulting in an accelerated loss of muscle mass. The
objective of this systematic review was to evaluate the ankle and foot muscle changes in diabetic
peripheral neuropathy using ultrasound.

Method:

A comprehensive search was conducted in Scopus, Embase, and PubMed databases,
which yielded 64 studies, out of which 5 studies are included in this meta-analysis.

Result:

The meta-analysis shows that the thickness and cross-section area of the extensor digitorum
brevis muscle are reduced in DPN as compared to the control group with p-value<0.004
and p-value<0.001, respectively. The thickness of MIL muscle was also smaller in DPN
p-value=0.02. Similarly, the thickness and CSA of AH muscle are also reduced in DPN patients
compared to the control group, with p-values of 0.21 and 0.14.

Conclusion:

Meta-analysis reveals that diabetic peripheral neuropathy (DPN) patients have reduced
foot muscle thickness and cross-sectional area (CSA) compared to controls without neuropathy.
This highlights the importance of ultrasound in detecting muscle atrophy early in diabetic
patients since it provides objective measures beyond traditional screening with its real-time
and non-invasive nature.

Published: September 2024

Son yıllarda, geleneksel seramik, metal ve polimerlerin yerini alabilecek üstün özelliklere sahip ve ekonomik açıdan avantajlı malzemelere yönelik ilgi önemli ölçüde artmıştır. Bu durum, malzeme bilimi ve mühendisliği alanındaki araştırmacıların dikkatlerini kompozit malzemelere yönlendirmesine neden olmuştur. Özellikle çevre dostu ve sürdürülebilir özelliklere sahip biyo-bazlı kompozitler, bu alandaki çalışmaların odak noktası haline gelmiştir. Bu araştırma çalışmasında, toz formda kullanılan muz kabuğu (MK) ve pirinç kabuğu (PK) oranlarının polimer kompozitler üzerindeki fiziksel, termal ve tribolojik etkileri incelenmiştir. Polimer kompozit üretiminde, atık kazanımına katkıda bulunması amacıyla geri dönüştürülmüş polipropilen (R-PP) tercih edilmiştir. Çalışma kapsamında yapılan deney sonuçları, organik atıkların R-PP’nin termal direncini artırdığını ortaya koymuştur. Ağırlıkça %30 konsantrasyonunda takviye ilavesiyle, ısıl çarpılma sıcaklığı (HDT) ve vicat yumuşama sıcaklığı sırasıyla %5 ve %4 oranında artış göstermiştir. MK/PK oranının artması yoğunluğu artırırken, aşınma oranının da artmasına neden olmuştur. Organik katkı maddelerinin yapısındaki hidrofilik bölgelerin nem çekme özelliği nedeniyle, maksimum takviye oranıyla polimer kompozitlerin nem emme oranı %36 artmıştır.

Published: September 2024

To present a rare clinical case of a man affected simultaneously by Becker phenotype Muscular Dystrophy (MD) and Klinefelter syndrome and the way how he was diagnosed. A 35-year-old man was evaluated in the context of hospitalization for respiratory failure. Since childhood, he had a clinical and muscle biopsy diagnosis of muscular dystrophy, possibly type Becker. His physical examination showed severe weakness of the pelvic and shoulder girdle, with a waddling gait, grade II scoliosis associated with tall height, obesity, and hypogonadism. Banding cytogenetics detected a sexual trisomy, 47, XXY in ~64% of peripheral blood cells. A heterozygote missense mutation in the dystrophin gene (DMD) was found in parallel using next-generation sequencing. Biparental origin, both X chromosomes suggest nondisjunction in paternal meiosis I, followed by a postzygotic trisomic rescue in a subset of fetal cells during embryonic development. Maternal inheritance of the DMD gene mutation was excluded, suggesting a de novo origin. This is the eighth case where Klinefelter syndrome and Becker phenotype Muscular Dystrophy are parallel. As the patient presents with relatively mild MD symptoms for his age, a skewed X-inactivation pattern in the 47, XXY cell line may be suggested.

Raw Photoplethysmography as an Enhancement for Research-Grade Wearable Activity Monitors
Authors: Hibbing Paul R , Khan Maryam Misal
Published: September 2024

Wearable monitors continue to play a critical role in scientific assessments of physical activity. Recently, research-grade monitors have begun providing raw data from photoplethysmography (PPG) alongside standard raw data from inertial sensors (accelerometers and gyroscopes). Raw PPG enables granular and transparent estimation of cardiovascular parameters such as heart rate, thus presenting a valuable alternative to standard PPG methodologies (most of which rely on consumer-grade monitors that provide only coarse output from proprietary algorithms). The implications for physical activity assessment are tremendous, since it is now feasible to monitor granular and concurrent trends in both movement and cardiovascular physiology using a single noninvasive device. However, new users must also be aware of challenges and limitations that accompany the use of raw PPG data. This viewpoint paper therefore orients new users to the opportunities and challenges of raw PPG data by presenting its mechanics, pitfalls, and availability, as well as its parallels and synergies with inertial sensors. This includes discussion of specific applications to the prediction of energy expenditure, activity type, and 24-hour movement behaviors, with an emphasis on areas in which raw PPG data may help resolve known issues with inertial sensing (eg, measurement during cycling activities). We also discuss how the impact of raw PPG data can be maximized through the use of open-source tools when developing and disseminating new methods, similar to current standards for raw accelerometer and gyroscope data. Collectively, our comments show the strong potential of raw PPG data to enhance the use of research-grade wearable activity monitors in science over the coming years.

Background. The massive russian military aggression against Ukraine has been continuing from February 24, 2022, and has caused the number of individuals who received combat wounds and psychological trauma to be significantly increased. After experienced traumatic events, the psychological changes appear first. They further strongly impact the physical condition of people. The acute stress which occurred after body injuring can further lead to the altering in the endocrine system. It is necessary to point out that during military conflict in Ukraine, the studying of hormonal influence on the particularities and rate of wound healing hasn’t been carried out. Therefore, the purpose of this work was to determine the connection between wound volume and altering of some hormone levels in blood serum at different stages of wound healing process in male combatants. Materials and methods. One hundred and twenty male combatants who were divided into 4 groups of 30 individuals depending on the wound volume have taken part in our investigation. The first group was the minor injuries; the second group — the moderate wounding; the third group was the serious injuries, and the fourth group (controls) included not wounded combatants. The certain periodization has been used depending on the processes which occur in the body in particular period: days 1–3, 4–5 and day 14 after wounding. The average age of patients was 34.2 ± 4.3 years, average body mass was 78.0 ± 3.5 kg. The concentrations of human growth hormone, testosterone, adrenocorticotropic hormone, aldosterone, thyroid-stimulating hormone, free triiodothyronine, free levothyroxine and dehydroepiandrosterone sulfate were evaluated. Results. The activating of practically all chains and complexes of endocrine system is its usual reaction to the injury. The main links between wound volume and serum hormone levels of combatants at the different stages of wound healing process have been revealed in our research. Conclusions. The metabolic response which occurs in human body independently of trauma severity is associated with necessity of the functioning of all organs and systems at the highest level in order to save lives of victims. The altering of all kinds of metabolism occurs. The metabolic signs of urgent adaptation are formed in the acute period of wound healing process related to katabolic processes. After that, the normalization of homeostasis with activating of anabolic processes gradually occurs. A positive correlation was found between the hormone levels and severity and term of injuring of male combatants. The continuation of monito­ring the hormonal status of male combatants with the involvement of large number of participants and detailing of wound localization, endocrinological history, neurological and mental status, hemodynamic parameters and the system of homeostasis is appropriate.

Background. Limb loss inevitably leads to changes in the physical, social, and mental domains that trigger a cascade of events: a more sedentary lifestyle, decreased ability to self-care, and increased use of health services. In addition, limb loss can negatively affect metabolic regulation and contribute to an increased risk of obesity and all associated metabolic consequences. The aim of the study was to justify the role of doctors of therapeutic specialties in the multidisciplinary team of the rehabilitation center based on the study of patients’ concomitant diseases. Materials and methods. The study included 379 patients from the Charitable Organization “Charity Fund “Superhumans”. They had an amputation and received a prosthesis and/or underwent rehabilitation from July 2023 to March 2024. Among participants, there were 9 women and 370 men, with an average age of 37.22 ± 9.74 years. Results. The role of doctors of therapeutic specialties in the multidisciplinary team of the rehabilitation center is substantiated based on the study of concomitant diseases of patients who have undergone amputation of one or more limbs. The study identified the following comorbidities: overweight (193 cases, 50.9 %), hypertension (108 cases, 28.5 %), liver damage of viral and non-viral origin (71 cases, 18.7 %), dyslipidemia (44 cases, 11.6 %), chronic gastritis (19 cases, 5.0 %), gastroesophageal reflux disease (15 cases, 4.0 %), rhythm disturbances (mainly sinus tachycardia or bradycardia) (14 cases, 3.7 %), chronic pancreatitis (11 cases, 2.9 %), duodenal ulcer (10 cases, 2.6 %), chronic cholecystitis (9 cases, 2.4 %), urolithiasis (4 cases, 1.1 %), chronic cystitis (4 cases, 1.1 %), chronic pyelonephritis (3 cases, 0.8 %), atrioventricular block (3 cases, 0.8 %), chronic obstructive pulmonary disease (2 cases, 0.5 %), bronchial asthma (2 cases, 0.5 %), autoimmune thyroiditis (2 cases, 0.5 %), nodular goiter (1 case, 0.3 %). Conclusions. Based on data obtained, the risks of progression of metabolic disorders and comorbidities in patients with limb amputations were determined.

The 2020 Indonesian Health Profile states that diarrhea is an endemic disease that has the potential to cause extraordinary events. Diarrhea is still one of the contributors to death in Indonesia, especially in children under 5 years old. This study aimed to evaluate the use of zinc and probiotic supplementation on the length of stay (LoS) of patients under 5 years old with diarrhea. It was an observational study using medical records of patients under 5 years old with diarrhea at the Academic Hospital, UGM Yogyakarta in the period of 2021 to 2022. Patient characteristics, including use and medications such as zinc supplementation and probiotics, as well as clinical outcomes including LoS were obtained from 100 medical records. Data were analyzed using chi square from Microsoft Excel 365 & Statistical Program for Social Science (SPSS) with a 95% confidence level (p<0.05). The majority of patients were male (61%) with age range 12-23 mo (47%), 3-4 times frequency of diarrhea (69%), dehydration mild-moderate (89%), and acute diarrhea (96%). The treatment of diarrhea was antidiarrheal (44.81%), fluid rehydration (32.55%), and antibiotics (22.64%). Most patients left the hospital in an improved condition and were allowed to go home (92%). There is a significant relationship between the use of zinc, probiotics, and a combination of zinc and probiotics on LoS.

Published: September 2024

Patients of intensive care unit (ICU) have a complicated condition due to disease, comorbid, and other risk factors. Some ICU patients need to get an invasive process to reduce pain, anxiety, and support their condition. During an invasive process, including mechanical ventilation which causes pain or anxiety, the patient is givensedative and analgesic agents to support the procedure and reduce the patient’s pain and anxiety. However, the use of fentanyl/midazolam has the potential to cause adverse effects, for instance, hypotension, hypoxia, and delirium in several ICU patients. Several risk factors that can lead to adverse effects are aging, obesity, underlying cardiac disease, and the amount of dosage. Therefore, it is essential to recognize the risk factors and monitor the use of fentanyl/midazolam to prevent the worsening condition of patients.

Rapid shelf-life of traditional supplementary drink still becomes major issue for herbal production in household industries. In this study the stability formula of an herbal suspension, so called as jamu kunyit-asam, was investigated. The jamu kunyit-asam Formula-1 (F1) contains combination of Citrus aurantifolia and Curcuma longa. While the Formula-2 (F2) is consisted by mixture of Tamarindus indica and C. longa. The two formulas were compared to justify better stability between preparations. No preservatives were added, in order to comply with the local regulation. To simulate the real situation, all samples were stored in 4 different conditions: opened bottle (room temperature), closed bottle (room temperature), closed bottle (refrigerator), and freeze-thaw condition. To evaluate the stability profile, an organoleptic testing and pH alteration were frequently checked for 12 consecutive days. Several parameters including color changing, sting odor, and microscopic appearance were looked over. As the results, mold, precipitation and pungent odor were formed faster from the F1 (C. aurantifolia combined with C. longa). These findings indicates that jamu kunyit-asam herbal drink suspensions containing C. longa has less stability in combination with the C. aurantifolia (F1) compared to the T. indica (F2).
