Gravitational redshift explained as a Doppler Effect in uniformly accelerated frames
Authors: Sfarti A.
Published: November 2023

Einstein predicted a change in the energy of photons in the proximity of a gravitational field, the change being directly proportional with the distance from the gravitational source. In the early 60’s Pound and Rebka have set to verify Einstein’s prediction. The experiment was reprised with even higher precision by Pound and Snider. Later, Vessot reprised the experiment in space at a much improved precision. The standard explanation of gravitational redshift falls out straight from the Schwarzschild solution of the Einstein Field Equations (EFE). In the following, we will present an approach to the experiment relying on the Einstein Equivalence Principle and on the recently derived expressions of Doppler Effect for uniformly accelerated motion of the source and the receiver. We will conclude with a chapter on the numerical limits of applicability of the described method.

Enhancing Equitable Access to COVID-19 Vaccination through the Implementation of Mobile Vaccination Clinics: A Community-Based Approach in Louisville, Kentucky
Authors: Brown Valenchia , Rashid Salwa , Chandler Thomas , Furmanek Stephen , Manson Delanor , Carrico Ruth
Published: November 2023

The COVID-19 pandemic has underscored the pivotal role of vaccination in preventing severe illness, hospitalization, and fatalities resulting from SARS-CoV-2 infection. This virus has disproportionately impacted minority communities, revealing a stark disparity in vaccination rates. The pandemic has worsened existing disparities in the United States concerning race, social status, and economic conditions, resulting in a greater risk of exposure to the SARS-CoV-2 virus, limited access to protective resources, and disparities in illness and increased death rates among individuals living in low-income neighborhoods, indigenous populations, and communities with predominantly non-white populations. Vaccine hesitancy stemming from mistrust of vaccine safety information and skepticism regarding traditional vaccination procedures has further exacerbated lower vaccination rates and higher COVID-19 hospitalization rates among non-white populations. This paper explores the transition from mass immunization to mobile vaccination clinics in Louisville, Kentucky, with a particular focus on the community-based versus community-placed approach. It outlines the training program and challenges encountered in the implementation of this crucial strategy during a dynamic pandemic landscape.

Published: November 2023

In this paper, we present a novel numerical scheme for a model involving novel mathematical concepts of significant importance for interpreting and examining real-world problems. This paper presents a numerical method for chaotic problems. Using differential and integral operators in the sense of Caputo-Fabrizio, we investigated the chaotic system of mathematical equations able to capture chaotic behaviour. Solutions are obtained for the fractional-order chaotic model using a fractional operator with a non-singular kernel. Uniqueness and boundedness for solution are proved through fixed point theory. Finally, we applied a numerical power series method to solve the proposed fractional model. Due to the high non-linearity of our problem, we used a suitable numerical scheme to solve this system of equations numerically.

Der Rundfunk Berlin-Brandenburg (rbb) kommt seit über einem Jahr nicht zur Ruhe. Nun soll sein Staatsvertrag im Zeichen der Schlesinger-Affäre novelliert, die Macht der Intendantin zugunsten diversifizierter Entscheidungsmodi beschnitten und ein Zeichen für Kontrolle, Transparenz und Regionalität gesetzt werden. Einige der mit dem Änderungsvorschlag des rbb-StV verbundenen Umgestaltungen der inneren Ordnung der Anstalt wurden in der medialen Öffentlichkeit kritisiert und in einem Kurzgutachten Joachim Wielands für verfassungswidrig befunden. Nach unserer Ansicht erscheint insbesondere die Verfassungskonformität der vorgesehenen zeitlichen Mindestvorgaben für die regionale Berichterstattung äußerst fraglich, an anderen Stellen handelt es sich jedenfalls rundfunkpolitisch nicht um einen großen Wurf für die Zukunft.
PENGARUH BIAYA PRODUKSI DAN HARGA JUAL TANDAN BUAH SEGAR (TBS) TERHADAP TINGKAT KEUNTUNGAN PADA PERKEBUNAN SAWIT RAKYAT DESA BANGUN HARJA KECAMATAN SERUYAN HILIR TIMUR KABUPATEN SERUYAN
Authors: Bandrang Tirsa Neyatri
Published: November 2023

Kelapa sawit (Elaeis guineensis Jacq) merupakan komoditas perkebunan unggulan dan utama Indonesia. Tanaman yang produk utamanya terdiri dari minyak sawit mentah (Crude Palm Oil atau CPO) dan minyak inti sawit (Palm Kernel Oil atau PKO) ini memiliki nilai ekonomis yang tinggi dan menjadi salah satu penyumbang devisa negara yang terbesar dibandingkan dengan komoditas perkebunan lainnya. Salah satu komoditi dari subsektor perkebunan yang mempunyai peran cukup penting dalam kegiatan perekonomian di Kabupaten Seruyan adalah kelapa sawit. Namun, sayangnya, perkebunan kelapa sawit di Kabupaten Seruyan masih di dominasi oleh pihak swasta termasuk penetapan harga jual. Berdasarkan gambaran lebih lanjut terkait permasalahan tersebut, maka dilakukan penelitian ke petani rakyat desa Bangun Harja dalam jangka waktu 3 bulan Mei sampai dengan bulan Juni 2021. Penelitian ini bertujuan untuk melihat pengaruh biaya produksi dan harga jual terhadap tingkat keuntungan petani rakyat. Dari 48 petani rakyat ini diperoleh bahwa terdapat pengaruh positif antar biaya produksi terhadap tingkat keuntungan petani. Berbeda dengan harga jual. Harga jual berpengaruh negatif terhadap tingkat keuntungan petani sawit rakyat. Hal ini dikarenakan harga jual ditetapkan oleh perusahaan sawit sehingga posisi tawar menawar petani sawit rakyat masih sangat rendah dan pada saat penelitian ini berlangsung terjadi anjlok harga TBS di tingkat petani. Secara simultan biaya produksi dan harga jual berpengaruh positif terhadap tingkat keuntungan petani Sawit. Berdasarkan hasil pengujian nilai korelasi antara biaya produksi terhadap tingkat keuntungan yakni 0,995 artinya biaya produksi memiliki keterikatan yang sangat kuat dengan tingkat keuntungan. Sedangkan harga jual memiliki tingkat korelasi -2,44 hal ini mengartikan bahwa harga jual berpengaruh nyata terhadap tingkat keuntungan.

Maintenance of a cement spacer as definitive treatment of post traumatic osteomyelitis, a case report.
Authors: McDermott Michael R , DiPasquale Luke , Rebic Ante , Steimle Jerrod
Published: November 2023

Background

Septic nonunion is a devastating outcome following a tibial plafond fracture, causing significantly increased morbidity and a lengthy recovery. Treatment options include antibiotics and irrigation and debridement procedures focused on preventing posttraumatic osteomyelitis. If these options fail, surgical intervention is necessary to clear infection and debride nonviable bone, often resulting in a substantial bony void. Masquelet technique and Cement augmentation are well studied, multi-stage procedures designed specifically for combatting these defects. These procedures are associated with significant patient burden, a long non-weight-bearing period, and a lengthy recovery. The case presented here today highlights a variation of these techniques that reduced the need for the standard second stage procedure and resulted in a quicker return to normal activity.

Case

A 51-year-old obese male presented with a septic nonunion with posttraumatic osteomyelitis following a tibial plafond fracture. The patient underwent implant removal with simultaneous irrigation and debridement of all nonviable bone resulting in a substantial bony void. The nonunion was then stabilized with an antibiotic tibial nail, and an antibiotic cement spacer to fill the bony void. The patient was allowed to partial weight bear post operatively and quickly progressed weight bearing status. By postoperative week eight, the patient’s activity level had returned to near his baseline, and the patient was not interested in another procedure to remove the spacer and bone graft. At this time, it was elected to permanently maintain the cement spacer, and only exchange it for bone graft as needed. By one-year, radiographic films demonstrating bony healing around the cement spacer, and the patient was back to full pain-free function.

Conclusions

Permanently maintaining the cement spacer in cement augmentation or the Masquelet technique allowed this patient to quickly progress weight-bearing status, regain function, and return to normal life without the need for the stage two procedure.

An Experimental and Numerical Evaluation of the Structural Performance of Concrete Beams Containing Bamboo Shear Reinforcement
Authors: Jahami Ali , Khatib Jamal , Bawab Jad
Published: November 2023

Alternatives to steel reinforcement in concrete are being actively investigated for environmental, economic, and durability concerns. Several studies suggest that bamboo is a potential substitute for steel reinforcement. In this study, the shear behavior of five reinforced concrete beams incorporating bamboo strips as shear reinforcement at different spaces and configurations were assessed. Structural concrete having a compressive strength of 25 MPa was used for this purpose. The experimental program involved applying four point bending test to the beams to determine their load deflection curves, crack pattern, and strain distribution. In addition, a numerical analysis was conducted for validation and prediction purposes. It was observed that including bamboo strips as shear reinforcement influenced a more brittle behavior with marginal differences when changing their spacing. On the contrary, the spacing was decisive for the load carrying capacity, as smaller spacing caused higher capacity. Strain distribution results followed a similar pattern to that of the deflection. All the curves exhibited a brittle shear failure evidenced by the crack propagation process. Further, the numerical study performed produced accurate results in comparison with the results obtained experimentally, in terms of both the load deflection curves and the crack pattern.
Isolation and Macroscopic Characterization of Molase and Alginate Bacteria from Mangrove Sediments in Shrimp Ponds
Authors: Al Falah Inda Hawa
Published: November 2023

Bacteria are microscopic organisms capable of thriving in various environments that support their growth, including mangrove sediment. Bacterial characteristics in mangrove sediment were examined using two different media: molasses and alginate. This process included preparing solid media, diluting sediment samples, isolating bacteria, and characterizing isolates. On molasses media (both Molasses Media I and Molasses Media II), bacteria generally displayed entire, undulate, and lobate margins, with diverse shapes (round, irregular, punctiform, rhizoid), colors (opaque, clear), and elevations (convex, flat, umbonate). On alginate media (Alginat Media I and Alginat Media II), after repetition, bacteria typically had entire and lobate margins, varied shapes (round, irregular, punctiform, rhizoid), colors (opaque, clear), and elevations (convex, flat, umbonate). Bacterial isolation utilized the spread plate technique on solid agar media, revealing higher colony growth on molasses media due to richer nutrients compared to alginate. Colony counts were determined via serial dilution, and bacteria displayed diverse macroscopic traits, evaluated using a comparison table considering colony margin, color, elevation, texture, and shape.
Selection on plastic adherence leads to hyper-multicellular strains and incidental virulence in the budding yeast
Authors: Ekdahl Luke I , Salcedo Juliana A , Dungan Matthew M , Mason Despina V , Myagmarsuren Dulguun , Murphy Helen A
Published: November 2023

Many disease-causing microbes are not obligate pathogens; rather, they are environmental microbes taking advantage of an ecological opportunity. The existence of microbes whose life cycle does not require a host and are not normally pathogenic, yet are well-suited to host exploitation, is an evolutionary puzzle. One hypothesis posits that selection in the environment may favor traits that incidentally lead to pathogenicity and virulence, or serve as pre-adaptations for survival in a host. An example of such a trait is surface adherence. To experimentally test the idea of ‘accidental virulence’, replicate populations of Saccharomyces cerevisiae were evolved to attach to a plastic bead for hundreds of generations. Along with plastic adherence, two multicellular phenotypes— biofilm formation and flor formation— increased; another phenotype, pseudohyphal growth, responded to the nutrient limitation. Thus, experimental selection led to the evolution of highly-adherent, hyper-multicellular strains. Wax moth larvae injected with evolved hyper-multicellular strains were significantly more likely to die than those injected with evolved non-multicellular strains. Hence, selection on plastic adherence incidentally led to the evolution of enhanced multicellularity and increased virulence. Our results support the idea that selection for a trait beneficial in the open environment can inadvertently generate opportunistic, ‘accidental’ pathogens.
Using synchronized brain rhythms to bias memory-guided decisions
Authors: Stout John J , George Allison E , Kim Suhyeong , Hallock Henry L , Griffin Amy L
Published: November 2023

Functional interactions between the prefrontal cortex and hippocampus, as revealed by strong oscillatory synchronization in the theta (6–11 Hz) frequency range, correlate with memory-guided decision-making. However, the degree to which this form of long-range synchronization influences memory-guided choice remains unclear. We developed a brain-machine interface that initiated task trials based on the magnitude of prefrontal-hippocampal theta synchronization, then measured choice outcomes. Trials initiated based on strong prefrontal-hippocampal theta synchrony were more likely to be correct compared to control trials on both working memory-dependent and -independent tasks. Prefrontal-thalamic neural interactions increased with prefrontal-hippocampal synchrony and optogenetic activation of the ventral midline thalamus primarily entrained prefrontal theta rhythms, but dynamically modulated synchrony. Together, our results show that prefrontal-hippocampal theta synchronization leads to a higher probability of a correct choice and strengthens prefrontal-thalamic dialogue. Our findings reveal new insights into the neural circuit dynamics underlying memory-guided choices and highlight a promising technique to potentiate cognitive processes or behavior via brain-machine interfacing.
Genetic analysis of two species of Mnomen in the Kalamazoo Watershed reveal panmixia in Z. Aquatica, structure among Z. Palustris, and hybridization in areas of sympatry
Authors: Kieleczawa Katarina A. , Luke Kaylee , Gregory Andrew
Published: November 2023

Mnomen or wild rice of the genus Zizania is an important part of Native American culture, especially in Michigan for the Ojibwe nation. An oil spill in 2010 along the Kalamazoo River and the subsequent clean-up lead to renewed interest in management of Mnomen within the Kalamazoo watershed. The affected water bodies were surveyed for Zizania species to map existing populations, determine the existing genetic diversity and species present, and to identify potential hybridization. Using Traditional Ecological Knowledge of rice beds and opportunistic sampling of encountered plants, 28 rice beds were sampled. Two species of Zizania were identified Z. palustris and Z. aquatica. Genetic diversity was measured using 11 microsatellite loci and was moderately high for both species (Z. aquatica HE = 0.669, H0 = 0.672, n = 26 and Z. palustris HE = 0.697, H0 = 0.636, n = 57). No evidence of population bottle-necking was found. Z. palustris was found to have k = 3 populations on the landscape, while Z. aquatica was found to be a single panmictic population. Several individual hybrids were confirmed using genotyping and they were all found in areas where the two species co-occurred. Additionally, Z. aquatica was found to have expanded into areas historically with only Z. palustris downstream of the oil spill, potentially due to dredging and sediment relocation as part of the clean-up effort.
Ergonomic analysis applied in aquaculture

Published: November 2023

Aquaculture plays a very important role in the current Brazilian scenario, helping the income of small families. This activity is considerably new and does not have a specific methodology developed for the fishing activity. Due to these factors, this ergonomic analysis at work (AET) study was carried out, with the purpose of identifying the causes of complaints of body pain and fatigue caused by this activity. For this analysis, the Ergolândia software was used, which is composed of several ergonomic methods. The method used in unloading was the National Institute for Occupational Safety and Health (NIOSH), which deals more specifically with lifting and transporting loads, which analyzes the weight of the load, position of hands and feet, inclination of the trunk, height of the load is raised. Collected data and images were also used as assistance. After carrying out the analyzes and verifying that at all stages the Lifting Index (IL) is above the recommended level, some improvement proposals were made to alleviate or eliminate these employee posture problems. All methodologies identified risk levels that require immediate or short-term ergonomic intervention, aiming to guarantee the safety and health of workers who carry out such activity. The implementation of measures designed to eliminate or minimize risk may involve the allocation of significant human and material resources, increasingly necessary for efficient management. Considering the complexity and variability of the tasks developed, it is recommended that such a decision be preceded by a new study using more precise risk assessment methodologies.

Authors: Joshi Roli , Singh Pankaj , Srivastava Shalini
Published: November 2023

Introduction: The thyroid gland regulates the basal metabolic rate, somatic growth, and physical growth. The thyroid gland plays a major role in the normal growth of a foetus during the prenatal period. There are few literatures on foetal thyroid gland. Aim: To study the various morphometric and histological changes during intrauterine life in both gender of human foetuses. Materials and Methods: This cross-sectional study was carried out in the Department of Obstetrics and Gynaecology, Dr. Sushila Tiwari Hospital Government Medical College, Haldwani (UK) and Saraswati Medical College, Unnao in the period of August 2015-2022. Government Medical College, Haldwani for duration of three years on medically terminated 70 foetus of both sexes of known gestational age ranging from 10 to 40 weeks. These foetuses were divided among three groups as group 1 (10-20 weeks), group 2 (21-30 weeks), group 3 (31- 40 week). Midline dissection of neck was done to expose the thyroid gland. Morphometric parameters like length, width, and thickness of each lobe and the isthmus were measured by digital Vernier caliper, weight was also taken by digital weighing machine, then tissue processing was done and paraffin blocks were prepared. All sections were stained with Haematoxylin and Eosin stain (H&E) and studied under the microscope aided camera. By using Analysis of Variance (ANOVA) test and Independent sample test (t-test) comparison among different age groups and gender has been done. Results: There was a significant increase in foetal thyroid weight, length and widths of the right and left lobes, and length of the isthmus with increase in gestational age, while no significant relation was found between male and female foetuses of measured morphometric parameter. The histological features revealed that development of thyroid gland starts earlier and thin capsule was seen at 12 week and it became thicker and more vascular till 35 weeks. Follicles started to form at 14 week and matured follicle were seen at the age of 24 weeks, at 25th week, the lining epithelium of follicles was low columnar to cuboidal, colloid material was seen almost in every follicle. C cells were found at 22 weeks. At the 36 weeks, the follicles were seen spherical and reached to maturity level. Conclusion: As the gestational age increases, the morphometric parameters must increase, if not so, it means the growth of gland is hampered. The knowledge of the growth and differentiation of foetal thyroid will be helpful for clinicians, to judge the thyroid structure prenatally.

A total of 127 formalin-fixed cadaveric brain specimens were used to measure the lengths of different parts of the lateral ventricle using a Vernier Calliper. Additionally, MRI scans of 35 patients were used to measure the same lengths. The mean values of the lateral ventricle lengths measured in formalin-fixed brain specimens and MRI scans were compared using Student’s t-test to determine statistical significance. Furthermore, variations in the lengths of the lateral ventricle according to age and gender were also measured using MRI. Results: Among the 127 brain specimens, 78 were from male brains and 49 were from female brains. Out of the 35 MRI scans, 23 were from male cases and 12 were from female cases. The average length of the frontal horn, body, and inferior horn was found to be greater in MRI scans (34.83 mm, 54.37 mm, and 51.09 mm, respectively) compared to the dissection method in cadavers (30.64 mm, 35.49 mm, and 42.29 mm, respectively). All parts of the lateral ventricle measured in MRI scans were found to have greater lengths in males, although the difference was not statistically significant. Conclusion: A significant difference was observed when comparing the lengths of the lateral ventricle measured in MRI scans and formalin-fixed cadaveric brain specimens.

This study examined village councils' transparency in managing Community-Driven Projects (CDPs) in Mlimba District Council, Morogoro Region, Tanzania. For project success, Community-Driven Development (CDD) strategies emphasize community engagement and local autonomy. CDP management relies on village councils to involve community members in decision-making to match projects with local priorities. This qualitative case study collected data from 24 purposively selected respondents of Chita and Ikule villages through interviews with village leaders and focused group discussions with village council members. The data were analyzed through a thematic analysis of how the village council practices transparency in CDP management. The study found that community meetings, notice boards, public speakers, and structured documentation increase transparency. Regular audits and project document accessibility ensure financial integrity. For CDPs to succeed, diverse communication, transparency, and community involvement were crucial. The study emphasizes CDP management transparency and inclusivity by highlighting diverse communication strategies to address local challenges. It is recommended that village councils maintain and continue to implement current transparency measures while enhancing and broadening their communication strategies. This may entail leveraging social media and digital platforms to effectively engage a wider audience, particularly the younger demographic. It is recommended that village council members undergo regular communication and community engagement training in order to enhance their current capabilities. Establishing a sub-committee within the village council's team that is specifically focused on enhancing transparency and communication strategies has the potential to enhance these endeavours. Communication strategies should be studied for their long-term effects on community engagement and project outcomes. Studies on how cultural and social dynamics affect communication in diverse communities could help tailor strategies to specific contexts.

Aquaculture stands as a vital marine economic sector in Vietnam's coastal provinces, with specific significance in Ba Ria - Vung Tau. The steady growth of this sector plays a pivotal role in local socio-economic development. However, this growth has led to legitimate concerns about environmental sustainability and socio-economic progress. Building on the findings from sociological surveys conducted through questionnaires and comprehensive interviews in 2022, this article has applied the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis method to pinpoint the existing issues that need attention in the aquaculture sector. Moreover, this study proposes strategies and guidelines for aquaculture development in a manner that ensures responsible environmental management while balancing economic growth with societal well-being. The aquaculture industry in Ba Ria-Vung Tau is presented with numerous growth opportunities, driven by the rising consumer demand for seafood consumption, ongoing technological advancements, and the pursuit of sustainable development goals. Yet, it has to navigate challenges such as resource scarcity, market competition, regulatory constraints, and the perpetual threats of climate change and disease. The industry's advancement is contingent on the collaboration of stakeholders to leverage strengths, address weaknesses, seize opportunities, and confront threats, all while minimizing adverse impacts on nature, ecosystems, and socio-economic aspects. To secure long-term sustainability, the industry must embrace prudent management practices, foster innovation, encourage collaboration, and proactively tackle these challenges. This work underscores the multifaceted nature of sustainable aquaculture and underscores the indispensable role of informed, forward-thinking management in ensuring its enduring viability.

Radon inhalation as well as ingestion through the use of water has a high potential of causing serious harm to sensitive cells and organs of the body when absorbed into the bloodstream. Therefore, this study aimed to assess the radiological health damage caused by radon in drinking bottled water available in Benin City, Edo State, Nigeria. Radon concentration was measured using a RAD7 electronic radon detector. The mean activity concentration radon is 137.18 ± 0.25 mBq/L. This mean value is slightly higher than 0.1 Bq/L recommended by the Standard Organisation of Nigeria but lower than the maximum contaminant level (MCL) of 11.1 Bq/L set by the United States Environmental Protection Agency and 100 Bq/L set by the World Health Organisation (WHO) for consumption of radon in drinking water. The mean total annual effective dose is 1.07±1.91 (\(\mu\)Sv/y) for infants, 0.61±1.09 (\(\mu\)Sv/y) for children, and 0.70±1.24 (\(\mu\)Sv/y) for adults. The computed annual effective dose to the public by inhalation and ingestion radon through the use of bottled water in the study areas are lower than the 0.1 mSv/y limit recommended by WHO. The estimated average for the age group excess lifetime cancer risk are 3.21 ± 5.71, 1.836 ± 3.26, 2.086 ± 3.71 (x 10-6) for infants, children and adults respectively. These values are below the world average permissible levels. Hence, consumption of the water examined poses no serious health risk to consumers.
Status of River Water in India: A Review
Authors: Kumari Pooja , Jangra Mohan Singh
Published: November 2023

Water means life which is a cyclic, inexhaustible, renewable prime natural resource. It is both a basic human need and a valued asset possessed by all living creatures. Hydrosphere, cryosphere, atmosphere, lithosphere and biosphere are all sources of water around the world. Water covers 71 % of the earth’s surface but only 1% of water is potable. Rivers like the Ganga, Yamuna and Sabarmati are revered throughout India. River water is critical for commercial and industrial development, hydroelectric power generation, agriculture, new multipurpose dams and tourism attractions. However, the presence of different contaminants such as pesticides, heavy metals, organic waste, chemical waste and direct sewage discharge has harmed the river's water quality. In India, river water pollution is a major issue that has harmed not only human and animal health, but also the economy of the country. In this review, a substantial number of studies on river water pollution in India are examined. Data on various physical, chemical, and biological characteristics are carefully analysed and interpreted, and it is discovered that river water in India is severely polluted. Furthermore, after careful interpretation of data and discussions published in research articles, this review explains the interrelationships among distinct physical and chemical parameters. EC and TDS are complementary to each other and temperature has a direct impact on pH and DO levels. Also, BOD and DO are reciprocally related with each other. This review provides a concise set of guidelines for assessing river water pollution and calculation of water quality index.
