Authors: Gschwantner Thomas , Schodterer Heimo , Kainz Christoph , Freudenschuß Alexandra 
Published: November 2024

Abstract
The initial development stage of forests forms the basis for the future tree generation. Various driving and interacting factors determine the regeneration process at small and large scale. Based on the latest Austrian National Forest Inventory 2016–2021 the regeneration assessments and estimation methods were collated. Analyses were conducted to estimate the forest area regarding regeneration necessity and occurrence, the causes of regeneration deficits, the origin from natural and artificial regeneration, tree species occurrence as well as browsing impact.
The results show a sea level gradient of increasing shares of necessary but missing regeneration, ranging between 15% at the lowest and 60% at the highest altitudes. Accordingly, high shares can be found in protective forest without yield (50%) and in the growth regions of the mountainous areas of the Alps (up to 40%). Due to the multitude of driving and interacting factors, the assessed causes of regeneration deficits show divers patterns. Light as a limiting factor appears to be more relevant at low altitudes, and competition through ground vegetation is highest at low and high altitudes. The influence of the humus layer on the seed bed was assessed to increase with altitude, as well as the impact of forest pasture, while game browsing as cause of regeneration deficits show no clear tendency over the analysed strata. About 91% of the necessary and occurring regeneration originates from natural regeneration and the remaining from artificial or a mixture of both regeneration types. The number of tree species in the ground vegetation layer decreases with altitude. Considering browsing impact the results show percentages of affected areas between 40% and 80%. The highest browsing impacts were found at intermediate altitudes between 600 and 1,500 m above sea level.
From a large-scale perspective as provided by NFIs, the results show divers patterns of regeneration necessity and occurrence and impacts on the regeneration. Representative large-scale monitoring by NFIs provides the opportunity to identify and quantify the adverse impacts and forest strata that are affected by regeneration deficits, and therefore support the development of forest management strategies that aim at the establishment of the future tree generation under changing climate conditions.
Legal Transformation of a Public Tertiary Institution: Turnaround and Public Interest of the Ghana Institute of Management and Public Administration (GIMPA)
Authors: Agomor Kingsley S. 
Published: November 2024

Abstract
Just over a decade ago, public tertiary institutions depended on the government for funding and received instructions on running their day-to-day affairs from the state. Recently, GIMPA a public tertiary institution deployed legal options to gain autonomy to stabilize its financial performance and service delivery. This article updates the progress that has since been made in understanding the reversal of the stressful financial situation of the institute through the lens of the existing legal framework. Further, the paper examined an ambitious organizational structure dwelling on a robust legal framework to redirect management policies, rules, regulations, and functional decisions of a public tertiary institution serving public management and public administration training and consultancy. Termed “legal framework,” this set of legal instruments is cultivated into efficient and effective operations that yield financial stability that ensures growth and is trajected towards national development.

Abstract

Introduction
The enteric nervous system (ENS) in the wall of the gastrointestinal tract is complex and comprises many neurons, which are differentiated in terms of structure, function and neurochemistry. Neuregulin 1 (NRG 1) is one of the neuronal factors synthesised in the ENS about the distribution and functions of which relatively little is known. The present study is the first description of the distribution of NRG 1 in the ENS in various segments of the porcine small intestine.

Material and Methods
Fragments were excised from the duodenum, jejunum and ileum of five euthanised Piétrain × Duroc sows, 18–20 kg in weight and eight weeks of age. Paraformaldehyde-fixed and dehydrated tissue was sectioned and double-labelling immunofluorescence was performed using Alexa Fluor-conjugated secondary antibodies to visualise neuregulin 1 and its colocalisation with vasoactive intestinal polypeptide (VIP), galanin (GAL), and the neuronal isoform of nitric oxide synthase (nNOS) in the myenteric and inner and outer submucosal plexuses, with PGP 9.5 serving as a pan-neuronal marker.

Results
Neuregulin 1 was observed in all enteric plexuses in each segment of the small intestine. The percentage of NRG 1-positive neurons ranged from 8.38 ± 0.55% of all neurons in the jejunal inner submucous plexus to 21.52 ± 0.98% in the duodenal myenteric plexus. Cells which were NRG 1-positive also contained VIP, GAL and nNOS in all segments of the small intestine to a degree which varied by small intestine segment and enteric plexus type.

Conclusion
The results indicate that NRG 1-positive neurons are present in the ENS of the porcine small intestine and differ significantly neurochemically, which may suggest a multifaceted role for NRG-1 in the controlling of the small intestine activity.

Abstract
Laboratoarele moderne de diagnostic dispun de un spectru larg de teste pentru hemostază utilizate în diagnosticarea și managementul pacienților cu tulburări hemostatice, în screeningul preoperator și în monitorizarea terapiei anticoagulante. Un studiu recent care a inclus laboratoarele de biochimie medicală și de transfuzie din Croația a evidențiat existența unor practici diferite în anumite etape ale procesului de testare a hemostazei și a evidențiat domeniile care necesită îmbunătățiri. Lipsa standardizării testelor, împreună cu nearmonizarea rezultatelor între diferite metode de măsurare, pot determina luarea unei decizii incorecte în tratamentul pacienților, compromițând astfel siguranța pacientului. Prin urmare, cu scopul de a sprijini laboratoarele să genereze rezultate exacte și de încredere, acest articol face recomandări cu privire la procedurile pentru fazele preanalitică, analitică și postanalitică ale celor mai comune teste de investigare a hemostazei: timpul de protrombină, timpul de tromboplastină parțială activată, timpul de trombină, fibrinogen și D-dimeri.

Abstract

Background
Acute kidney injury (AKI), a medical condition associated with increased hospitalization rates which requires interdisciplinary management, is a major health concern because of the burden it places on the health systems of different countries. Biomarkers represent the focus of recent years in furthering the early diagnosis of AKI, providing new opportunities for correct prophylaxis or early therapeutic intervention so that the evolution of patients with this pathology is favorable and the risk of life-threatening complications is negligible.

Methods
We performed an extensive literature search on PubMed and ScienceDirect databases, using keywords related to bio-markers for AKI. We searched for acute kidney injury (AKI), cystatin C (CYS-C), galectin-3 (GAL-3), kidney injury molecule-1 (KIM-1), neutrophil-gelatinase-associated lipocalin (NGAL), interleukin-8 (IL-8), and liver-type fatty acid-binding protein (L-FABP). We included a high number of papers, with an emphasis on more recent publications.

Results
Studies that analyzed the biomarkers for AKI show that CYS-C, GAL-3, KIM-1, NGAL, IL-8, calprotectin, and proteinuria were noted as potential biomarkers for early diagnosis of AKI.

Conclusions
Biomarkers represent the focus of recent years in furthering an early diagnosis of AKI, providing new opportunities for correct prophylaxis or early therapeutic intervention.

Authors: Mezzanotte Valeria , Brivio Sforza Emilio 
Published: November 2024

Abstract
PFAS (per- and poly-fluoroalkyl substances) is a complex family of manmade highly fluorinated aliphatic organic chemicals including thousands of chemical structures identified. A research was carried out at a municipal wastewater treatment plant (MWWTP) in Northern Italy to define the inflowing load of PFAS, the main load sources and the removal efficiency of the treatment processes. Then, the 100 industrial settlements served by the MWWTP were examined, and 8 of them were selected as potential PFAS sources. The calculated loads summed up to 98.5 % of the total load entering the plant. The removal in the WWTP was null and, in some cases, negative. As also reported in the literature some precursors can be transformed in PFAS during the biological process and some sludge accumulated compounds can be released.

Published: November 2024

Abstract
A hypothesis is proposed on the possibility of creating a gas turbine electric power-generating device working on fuel gas, and propane, and the results of preliminary research experiments are given to evaluate the validity of this hypothesis. The criteria for mixing fuel gas-propane with air and assessing the quality of combustion have been identified. In particular, the colour of the fuel gas combustion and the force acting on the gas turbine blade of the flue gas flow injected from the combustion chamber. At atmospheric pressure, without heating, the optimal content of the mixture of propane and air, and the force acting on the gas turbine blade have been experimentally determined. An experimental relationship between the force acting on the gas turbine blade and the diameter of the combustion chamber has been obtained, by which it is possible to determine the diameter and height required for the chamber of a specific capacity according to the force acting on the gas turbine blade. A simplified method is proposed to determine the possible amount of electrical energy depending on the force acting on the gas turbine blade. It has been shown that when burning an optimal mixture of propane with air, two chambers with a capacity of 0.1 m3 can ensure the nominal operation mode of a 1.5 kW capacity electric generator.
Study of the Microbiological Efficiency of a Hospital Ventilation System With Hepa Filtration in the Prevention of Airborne Pathogens
Authors: Santos Ricardo Andrade , Hasslocher-Moreno Alejandro Marcel 
Published: November 2024

Objective: To evaluate the microbiological efficiency in air conditioning systems with HEPA filtration in an infectious disease hospital.

Theoretical Framework: Air conditioning in intensive care units and wards must consider the spread of microorganisms through respiratory pathways, as both patients and healthcare professionals are exposed to infectious agents transmitted by bioaerosols. Due to the possibility of environmental infection, there is a growing recognition that poorly designed air conditioning systems enhance the transmission of pathogens in areas with constant flow of individuals, particularly immunocompromised patients, who are more susceptible to infections. Air conditioning with HEPA filtration is a hospital engineering technique that shows great potential for filtering airborne contaminants, thereby reducing their dispersion in the environment.

Method: Air samples were collected using the active impaction method over a 32-week period in the intensive care unit and wards of a reference hospital for infectious diseases.

Results and Discussion: In the hospital environment, 67% of fungi and 33% of bacteria were identified, along with their respective subcategories. The colony-forming unit count exceeded the standards established by current regulations. The study highlights that hospital air is a pathway for the transmission and persistence of pathogenic microorganisms.

Research Implications: The importance of ensuring a safe and healthy hospital environment is emphasized.

Originality/Value: There are few studies addressing pathogens transmitted by bioaerosols. This study contributes to expanding knowledge on this topic and suggests the need for a review of current regulatory standards.

Translate and cross-culturally adapt the original English version of the lower extremity functional scale into the Sinhalese version
Authors: Thebuwanaarachchi Sanka Theekshana 
Published: November 2024

Objectives:
Functional ability is critical for quality of life (QOF), and its evaluation is vital in a clinical context. However, there is a deficiency of a universally recognized grading scale in Sinhala for assessing functional capacity in athletes with lower extremity musculoskeletal conditions. This research aimed to validate the linguistic and cross-cultural adaptation of a translated Sinhala version of the lower extremity functional scale (S-LEFS).

Materials and Methods:
A two-stage observational study was conducted. The lower extremity functional scale was cross-culturally adapted to Sinhala through independent, double forward, and backward translation. An experienced clinical researcher tested the translated version to establish the linguistic validation of S-LEFS. The finalized version was validated for construct, convergent, and criterion validity. A total of 112 participants, comprising 57 healthy (50.89%) and 55 unhealthy (49.11%) lower limb athletes, completed S-LEFS.

Results:
S-LEFS demonstrated excellent reliability with a Cronbach’s alpha of 0.952. Exploratory factor analysis revealed good factor loadings (>0.48) for all 20 items, with three components accounting for 70.63% of cumulative variance. Scale got a sensitivity of 87.5% and specificity of 81% at a cutoff point of 67.5. Kaiser-Meyer-Olkin (KMO) value was 0.918 (P < 0.0001), and Bartlett’s Test of Sphericity was significant (P < 0.01). No correlation was detected between S-LEFS and World Health Organization QOF-Bref (r = 0.281).

Conclusion:
S-LEFS is a reliable and valid tool for evaluating lower limb function in athletes.

Published: November 2024

In this paper, we have constructed a five-dimensional Bianchi type I cosmological model with strange quark matter in the context of Saez-Ballester theory of gravity. We have discussed a five-dimensional cosmological model by using the special rule of variation for the Hubble parameter in the shape of H = Da-1 and the equation of state for strange quark matter. Two different models for n ≠ 0 and n = 0 have been discussed. Also, the accelerated expansion of the Universe has been discussed by using various physical parameters and its graphical representation.

Published: November 2024

Perovskite-based solar cells are currently attracting growing interest from researchers and industry alike, thanks to the advantages of this type of solar cell, particularly in terms of manufacturing simplicity and the promising power conversion efficiency, which has recently reached remarkable levels. This paper focuses on numerical simulation to improve the performance of the Formamidinium Tin Iodide (FASnI3) solar cell configuration by using Cerium Dioxide (CeO2) as ETL and Poly (Triaryl Amine) (PTAA) as HTL. The simulation has been carried out using Solar Cell Capacitance Simulator (SCAPS-1D) tool under the spectrum of AM 1.5 G. An intensive modeling has been realized to improve the output parameters of the suggested configuration based on FASnI3 as absorber. The proposed structure (ITO/CeO2/FaSnI3/PTAA/Au) achieves a tremendous power conversion efficiency (PCE) of 39.24%, an open-circuit voltage (VOC) of 1.31 V, a short-circuit current density (JSC) of 33.7 mA/cm2 and a fill factor (FF) of 90.12%.
Effectiveness of A Combination of Kitolod Leaves (Laurentia longiflora), Papaya Leaves (Carica papaya), and Lemongrass (Cymbopogon citratus) as Candidates for Biocides on Bactrocera Pests in Citrus sinensis Plants

Published: November 2024

Bactrocera is a pest that is detrimental to citrus farming. Bactrocera attacks cause developmental disorders in citrus fruit, including changes in fruit color (black spots appear from Bactrocera infection) and premature rot. Bactrocera also has a symbiotic relationship with Liberibacter asiaticus which causes Citrus Vein Phloem Degeneration (CVPD) disease which attacks phloem tissue in citrus plants. Bactrocera pest control was carried out by combining plants that have the potential to be used as biocides, namely kitolod, papaya, and lemongrass plants. This combination was used to switch the habits of fruit farmers who previously used synthetic pesticides to control pests. Natural biocides are expected to have the same effectiveness as synthetic pesticides, but leave no residue on cultivated plants. A combination biocide from the three plants was made using the maceration method to obtain an infusion from each plant. Before being tested on Citrus plantations, an assay was carried out using an olfactometer to determine the effectiveness of the biocides. The research revealed that the combination of these three plants has the potential to be used as a natural biocide without leaving residueand causing damage or other developmental disorders to citrus plants.

The effect of atherosclerotic lesions of the carotid arteries (CA) on the success of the cognitive function recovery procedures in cardiac patients has not been sufficiently studied. This study aims to evaluate the effects of cognitive rehabilitation depending on the presence of CA stenosis in patients after coronary artery bypass grafting (CABG) using neurophysiological indicators.Material and methods. The cohort prospective study involved 85 patients (16 of them women), aged 45 to 75 years, admitted for elective CABG. All patients underwent standard clinical and instrumental, neurological, extended neuropsychological and neurophysiological examination.Results. After multi-task training, the patients with CA stenosis had higher levels of high-frequency beta power (13-30 Hz), while the spectral power of the alpha1 rhythm (8-10 Hz) in this group was lower compared to patients without stenosis. In the case of successful cognitive rehabilitation (absence of POCD) at 11–12 days after CABG, compared with the group with POCD, patients without stenoses had higher total power of alpha 1 power and lower — beta power than patients with stenoses CA.Conclusion. The absence of CA stenosis in the patients with successful completion of multi-tasking training contributed to the optimization of brain activity with an increase of alpha power. Whereas the patients with CA stenosis were characterized by an increase in high-frequency brain activity, both in the case of successful multi-tasking training and in its absence, in the early postoperative period of CABG. This study may serve as a basis for the development of special cognitive rehabilitation programs for patients with atherosclerotic lesions of the carotid system.
