Authors: Fathabad Mohadeseh Nazari , Raesi Rasoul , Hushmandi Kiavash , Hosseini Motahreh , Soleimani Anoshirvan , Daneshi Salman
Published: June 2024

Background

Melasma is a chronic skin disorder that is characterized by the accumulation of irregular brown pigments in the skin. Lesions are usually seen on the forehead, temples, upper lip, and cheeks. This disease is one of the most common reasons for women to visit dermatologists.

Aim

The present study was conducted to determine the clinical and epidemiological characteristics of melasma in women referred to the dermatology clinic.

Methods

This is a cross-sectional study that was conducted on 100 women who were referred to the dermatology clinic of Imam Khomeini Hospital in Jiroft City in the first half of 2021 using a convenient sampling method. Data were collected using a researcher-made checklist and analyzed using SPSS-v20 statistical software and descriptive and inferential tests at a significance level of p˂0.05.

Results

The average age of women with melasma was 32.8±0.64 years. The majority of clients had skin type four (57%) and skin type three (30%). The spread of pigmentation was mainly centro facial (62%), and there was a positive family history in 43% of cases. Moreover, it was found that melasma is not related to any of the variables of age, number of children, duration of the disease, marital status, family history, history of hormonal treatment, history of pregnancy and subsequent exacerbation, thyroid disease and polycystic ovary syndrome, and use of night creams and sunscreen.

Conclusion

Melasma is a relatively common disease in Iran. Additional studies are needed to find the epidemiological and underlying variables and treatment of melasma.

A seizure is the brain's uncontrolled, abnormal electrical activity, which may result in
altered states of consciousness, behavior, memory, or emotion. Seizures start biologically with the
activation of susceptible brain neurons, which causes synchronized discharges of larger groups of
connected neurons. A few potential causes of seizures include medications, genetics, electrolyte abnormalities,
sleep state, infections, brain inflammation, and injuries. Medicinal plants are a rich
source of various chemical molecules with distinct structures and biological activity. Most plants
contain active components, including coumarin, glycosides, alkaloids, terpenoids, flavonoids, peptidoglycans,
and other elements often associated with the effects of antiseizures. Isolating and identifying
biologically active compounds and molecules from nature have resulted in the development of
novel treatments, which in turn have contributed to the advancement of the health and pharmaceutical
sectors throughout the history of humanity. In this review, we thoroughly summarize the information
on the anti-seizure activities of medicinal plants and bioactive chemicals, focusing on molecular
targets and cellular signaling pathways. All available research has contributed to medicinal
plants as a reasonable option for seizure prevention and treatment, as well as drug development and
manufacturing. To better comprehend the underlying molecular mechanisms, more research is required.
If these mechanisms are discovered, it will be easier to identify new targets and create innovative
anti-seizure therapeutic drugs to enhance patient survival and life quality. This work is expected
to provide insights and ideas for the further research of Bioactive compounds from medicinal
plants, their qualities, and the scientific basis for their improved clinical use.
Conformational Dynamics of Post-Translational-Modified α-Synuclein
(pY39 and pS87) and its Interaction with Lipid Membrane
Authors: Das Dorothy , Mattaparthi Venkata Satish Kumar
Published: June 2024

Background:

The biological function of α-Synuclein (α-Syn), which includes controlling
synaptic vesicles, is regulated by phosphorylation at the Tyrosine 39 (pY39) residue. This
function can be important for both normal and aberrant functions, and it relies on the interaction
of α-Syn with the lipid membrane. pY39 α-Syn is found to form morphologically distinct fibrils
relative to wild-type (WT) α-Syn and shows less affinity to negatively charged vesicles. Also, the
phosphorylation at position Serine 87 (pS87) is increased in synucleinopathies, which inhibits α-
Syn oligomerization and affects the interaction between α-Syn and the membrane.

Objective:

This work aimed to study the effects of post-translation modifications of α-Syn (pY39
and pS87) using all-atom Molecular Dynamics (MD) simulation.

Method:

In this computational study, we used all-atom MD simulations to investigate the effects
of phosphorylation (pY39 and pS87) on protein-membrane interaction. The MD trajectories obtained
were analyzed, and secondary structural content was calculated using YASARA software
to perform a salt-bridge interaction study. Also, Principal component analysis was performed to
analyze the secondary minima and global minima of the phosphorylated proteins.

Results:

From the MD study, we observed that phosphorylation at the Tyr 39 position in α-Syn
has a marked effect on its interaction with the lipid membrane. The conformational snapshots of
α-Syn obtained showed a high degree of fluctuations in the N-terminal region that disrupts the helix-
2 binding region. The secondary structures of pS87 α-Syn were found to be retained and influence
the NAC region to immerse into the membrane while inhibiting the potential to interact with
other neighbouring molecules. Moreover, it was observed that in the case of pY39 α-Syn as opposed
to pS87 α-Syn, there were larger energy disparities between the local and global minima of
the overall structure.

Conclusion:

Therefore, disruption of the helix-2 binding region may affect the binding to the lipid
membrane and take over interaction with other proteins or vesicles. In the case of pS87 α-Syn, the
structure showed higher stability, but the NAC domain was found to emerge out of the membrane.

Authors: Dutta Srabona , Ghosh Sourav , Rahaman Monosiz , Chowdhury Sejuti Ray
Published: June 2024

Small extracellular vesicles called exosomes, which cells release, have drawn a lot of attention
recently because of their ability to serve as therapeutic delivery systems for drugs and regenerative
medicine applications. The investigation of plant-based exosomes as a cutting-edge platform
for drug administration has emerged as an enticing research topic. A summary of the pharmaceutical
feasibility of exosomes generated from plants and their uses in drug delivery along with regenerative
medicine are the goals of this review study. Plant exosomes can be combined into nanoparticlebased
medication delivery systems to increase their stability, targeting, and cargo delivery capabilities.
By loading plant exosomes with therapeutic compounds and encapsulating them within nanoparticles,
controlled release and targeted distribution to specific cells or tissues may be achieved. In
gene therapy, plant exosomes can be modified to carry nucleic acids like plasmid DNA, siRNA, or
miRNA. Effective gene delivery and therapeutic gene expression regulation can be accomplished by
encasing nucleic acids in exosomes or surface-modifying exosomes to improve their interaction with
target cells. In this review, we through the history and features of plant exosomes, examine how they
differ from mammalian exosomes, and consider how they may be used for gene therapy, tissue regeneration,
and targeted medication delivery. The difficulties and prospects for creating exosomebased
plant medicines are also explored.

Published: June 2024

The development of new courses, the preparedness of instructors, and the
Covid 19 pandemic have each contributed to the emergence of difficulties at
universities. This research examines the possibility for Open Journal Systems (OJS),
which was hitherto merely a manager of periodic electronic scientific publications, to
become a new learning platform for thesis proposal development courses (TPD) during
the Covid-19 pandemic. This is based on two factors: (1) the features of the OJS
editorial review process that are used in the consultation process between supervisors
and students; and (2) the recording function of OJS that will store assistance data along
with the results of the review that are organized in a review article session that is
divided into multiple sections in OJS. Students are required to be able to generate a
thesis proposal and comprehend the scientific publication process, which is a
requirement for graduating from their program of study.

Fly ash as coal burning waste contains a variety of main compounds such as CaO, SiO2, Al2O3, Fe2O3, MgO, MnO, Na2O, K2O and some heavy metals. The composition of each compound is different depending on the combustion condition parameters in the industry. Rice husk waste reaches 20-30% of the grain produced and has not been utilized optimally by farmers. Therefore, the use of a mixture of fly ash and husk requires further study as an innovative soil improvement product. The aim of this research is to identify the use of fly ash and rice husks as environmentally friendly soil amendments or fertilizers. Fly ash is mixed with organic components such as burnt husks, goat manure with different compositions. The product obtained is then placed in the soil of the chili plants using the method of spreading 0.5 g on 1.5 kg of soil. Tests were carried out both on the soil regarding the value of the degree of acidity and humidity and the growth of chili plants as indicators of the effect of adding fly ash on their growth. The results of fly ash waste can be used as a soil conditioner with a range of acidity between 6.5 to 8.5 fly ash with a nitrogen content of 0.49%, 0.18% phosphorus, 0.6% potassium with a carbon value of 6.9% and C/N ratio 14.08. These conditions are good for the soil for chili plants. The increase in height increases on days 1 to 9, while leaf width tends to remain constant on days 3 to 9. The results of this research contributes on the developing the use of fly ash in agriculture so that the absorption of fly ash waste can be done on a large scale.

Published: June 2024

Leaves of citronella (Cymbopogon nardus L.) have pretty much essential oil. Essential oil from citronella leaves is generally extracted by conventional methods. Conventional method is still less effective. The problem can be overcome by using non-conventional methods in the form of UMAE (Ultrasound-Microwave Assisted Extraction). UMAE is an extraction process assisted by ultrasound and microwaves. NaCl solution can be used as a solvent in the UMAE method because NaCl has a large dielectric constant. The aim of this study was to examine the effect of extraction time and the addition of salt on the yield and color of essential oils produced using the UMAE. The extraction process begins with the raw material preparation stage, such as harvesting, size reduction, and drying. Then, pre-treatment was carried out using ultrasound for 5 minutes at 35oC with the addition of 2, 4, 6, 8, and 10% (w/v) salt. Pre-treatment results were followed by the extraction process using microwaves for 30, 45, 60, 75, and 90 minutes. The best results were obtained with the addition of 6% salt and 60 minutes of extraction time with a feed to solvent ratio of 0.1 with a yield of 1.975% and the color is yellow.

This article resurfaces an enslaved female whom we encounter, drowning, in the archive of the Middelburgse Commercie Compagnie (MCC). To unfold a reading beyond the transcription of her commodified death, I investigate the five localities that conditioned her bodily inscription into history: the archive, the law, the ship, the ocean, and the womb. Traveling through these localities, I disclose, at once, the historical violence against black females through the transatlantic slave trade system and the excess black females proved to be to this very system. Excessive thus, black female lineage provides an alternative to white, patriarchic systems of relation.
Opacity in Open Air: Producing Queer Outsides through Glissant’s Poetics of Relation
Authors: Garea Albarrán M.
Published: June 2024

This essay provides a queer reading of Édouard Glissant’s critique of Western metaphysics as presented in his 1990 work Poetics of Relation. Glissant’s text is interpreted as offering conceptual tools for understanding the production of an outside of the gender binary, as well as for a critique of the naturalisation of the bourgeois framework underlying queer visibility and inclusion as political ends. Based on the self-transgressive character shared by the notions of Relation and queerness, it is further argued that both the potentialities and the aporetic elements of Glissant’s proposal can elucidate those of queer theories and practices.

This research investigates how different online payment methods impact the behavior of consumers, the efficiency of banking services, and the overall economic growth of the e-commerce industry. The study focuses on how Generation X online shoppers in Thailand perceive and use online financial services. A survey conducted between January and April 2023 gathered data from 400 participants. By using statistical methods like mean rating, standard deviation, and structural equation modeling (SEM), the study revealed important insights. While the ease of using online services did not directly affect transaction behavior, the study found that the perceived usefulness indirectly influenced behavior through ease of use, highlighting the importance of usefulness as a mediator. By enhancing the perceived usefulness of online financial services, businesses can strengthen this mediating role between ease of use and service usage. This strategic approach can enhance user engagement, foster loyalty, and promote early adoption of online financial services.
Unlocking Loan Approval: Data-Driven Insights and Machine Learning Precision
Authors: Jain Sameer
Published: June 2024

This research study explores the realm of loan approval prediction, leveraging a comprehensive dataset encompassing a wide array of applicant-related variables, including loan parameters, credit scores, education, and asset holdings. The primary objective is to construct an effective predictive model to aid lending institutions in making informed decisions regarding loan applications. Furthermore, this study identifies key factors that significantly influence loan approval determinations, offering insights into prioritising services for applicants with higher approval probabilities. The dataset employed in this study comprises critical financial information typically used to assess loan eligibility, such as CIBIL scores, income, employment status, loan terms, loan amounts, asset values, and loan status. Employing advanced machine learning and data analysis techniques, this research develops predictive models capable of estimating the likelihood of loan approval based on these features. Key findings reveal that a higher CIBIL score positively correlates with increased chances of loan approval, while a larger number of dependents diminishes approval probabilities. Additionally, applicants with more substantial assets, encompassing both movable and immovable holdings, are more likely to secure loan approval. Furthermore, individuals requesting higher loan amounts with shorter tenures exhibit greater odds of approval. The research employs machine learning models, including the Decision Tree Classifier and Random Forest Classifier, to forecast loan approval outcomes. These models yield impressive accuracies of 92.98% and 90.98%, respectively, with the Decision Tree Classifier outperforming the Random Forest Classifier within this context.

Published: June 2024

BACKGROUND

Symptoms and side effects change frequently during outpatient cancer treatment. As electronic patient-reported outcome (ePRO) systems used in oncology have become more common, they have been primarily designed to collect symptoms from patients and shared with providers without making the data collected available to patients. The goal of this study was to develop and evaluate ePRO and sensor data visualizations that patients could access online during chemotherapy.

OBJECTIVE

The goal of this study was to develop and evaluate patient-facing ePRO and sensor data visualizations that patients could access online during chemotherapy.

METHODS

As part of an ongoing NCI-funded study to develop a remote symptom monitoring system, we created mobile-friendly web visualizations of daily symptom ratings, wearable data and self-management resources, available to patients undergoing chemotherapy. At the end of the three month study, 141 patients completed a survey.

RESULTS

Survey respondents were heterogenous in age (M 61 years old, range 29- 92 years old), race (80%, 113/141 white, 20%, 28/141 other) and cancer stage (56%, 75/135 Stage IV). About half (54%, 76/141) of participants accessed the link to their data visualizations. There were no significant differences between the participants who did and did not click the link during the study in terms of average age (P =.74), gender (P =.66), race (P =.50) or cancer stage (P =.31) . Of those who accessed the platform, most (54%, 41/76) viewed it a few times, while 13% (10/76) used it daily. Most (77%, 58/75) believed it was “Somewhat” or “Very Helpful/Informative.” All ten daily users joined the study within three months of starting chemotherapy for the first time.

CONCLUSIONS

Findings suggest that patients new to chemotherapy may be most interested in viewing visualizations of daily symptom and sensor data and that the web application is widely accessible for patients of different ages, races, and cancer stages.

En defensa del territorio ancestral: activismo, peritaje antropológico y juicio agrario
Authors: Velázquez Solís Alberto C.
Published: June 2024

En este artículo se describe un conflicto territorial entre dos ejidos que se remonta a la década de los ochenta, cuando las autoridades agrarias crearon un segundo núcleo que fue dotado con tierras, que previamente habían sido asignadas al ejido de Kanxoc. A raíz de este conflicto, se inició un juicio agrario que continúa sin resolverse. Dentro de ese litigio, se solicitó un peritaje antropológico, por parte del ejido de Kanxoc, para determinar la posesión ancestral que han tenido como pueblo maya y esclarecer el proceso histórico por el cual se dotó dos veces una misma superficie de tierra. En este documento, se reflexionan algunas aristas sobre el peritaje antropológico desde el papel del activismo en la defensa del territorio.
Apuntes teórico-metodológicos para investigar la relación entre jóvenes y política
Authors: Suárez Zozaya María Herlinda , Torres Martínez Rubén
Published: June 2024

El objetivo de este texto es presentar aspectos nodales del pensamiento de Hannah Arendt que pueden servir para comprender la condición juvenil contemporánea, visibilizando particularmente la complejidad de la vida política de las personas jóvenes. En este sentido, se señala la importancia de atender su aparición en el espacio público considerándoles “recién llegadas”, portadoras de la novedad, que buscan inclusión en un mundo que ya existe. La propuesta es enmarcar las tensiones inherentes al encuentro entre generaciones en la tesis de Arendt sobre las crisis de autoridad, revelando que en la actualidad la crisis es enorme. En este marco, se ponen de manifiesto las relaciones que guardan las nociones de condición juvenil, diversidad y clivajes con los conceptos arendtianos de condición humana, pluralidad y novedad. El texto es resultado de una investigación documental basada en la revisión analítica, no exhaustiva, de la obra bibliográfica de Arendt, a la luz de los requerimientos teóricos y metodológicos planteados por un proyecto de investigación sobre estudiantes, condición juvenil y participación política actualmente en desarrollo.
Un acercamiento a la introducción de esclavizados a Campeche a través del Asiento de Negros de Inglaterra (1713-1739)
Authors: Victoria Ojeda Jorge
Published: June 2024

Estas líneas abordan la participación de Campeche en el Asiento de Negros concedido a Inglaterra por parte de España, de 1713 a 1739. La introducción de gente esclavizada a través del puerto de Campeche de manera legal, tuvo su mayor índice durante la primera mitad del siglo xviii, debido al Asiento señalado, no obstante que aquella villa no fue considerada entre los puntos para las factorías de llegada y venta dentro del Tratado de 1713. El interés forestal y la expansión comercial de los ingleses abarcó el territorio yucateco, y establecieron en Campeche una “factoría” que subarrendaron a otros comerciantes radicados en Jamaica. A pesar del descontento de España, la “factoría” fue “oficializada” con la designación de una autoridad española que la supervisara. Los diversos acervos históricos consultados y las investigaciones precedentes, confirman que, durante las dos décadas de ese Asiento en Campeche, la migración legal forzada ascendió, hasta donde se sabe, a poco más de 800 esclavizados.
Migrantes catalanes en el comercio maderero desde la Laguna de Términos (finales del siglo XVIII-siglo XIX)
Authors: Torras Conangla Rosa
Published: June 2024

Con la apertura de puertos al comercio atlántico, se extendió la posibilidad para Campeche de comerciar con Barcelona y otros puntos de la costa catalana. Entre 1784 y 1796, Barcelona fue el segundo puerto —después de Cádiz— receptor de palo de tinte procedente de Campeche, Veracruz y La Habana. Ello impulsó la llegada de migrantes originarios de pueblos costeros catalanes quienes se introdujeron a la economía extractiva forestal en auge, en ese periodo, en la cuenca de la Laguna de Términos (partido del Carmen, Campeche). A diferencia de muchos de ellos, que regresaron e invirtieron sus fortunas en sus territorios de origen —los indianos—, es notoria la presencia de catalanes que se quedaron en tierras campechanas, insertándose en las élites asentadas tanto de la villa del Carmen como en San Francisco de Campeche. El presente artículo se propone indagar en las trayectorias y estrategias de dicho grupo migratorio, así como en su presencia en la conformación de imaginarios coloniales regionales.
Domestic Servitude: Socio-Cultural Isolation and Coercive Labour Relations in Peru
Authors: Schalkowski Nicola
Published: June 2024

This article proposes a historical-sociological lens to approach coercive and violent relations within remunerated household labor. Drawing from Orlando Patterson, these relations are understood as interpersonal relations of domination with the concept of domestic servitude. They are analyzed in a qualitative empirical case study on socio-culturally isolated domestic workers in Lima, Peru. While the paper attends to scholars concerning migration and domestic work, its main sociological contribution is to empirically and theoretically enrich debates on “unfreedom” beyond economic exploitation. It argues for a reflective and differentiated elaboration on socialcultural dimensions of coercion and violence that are embedded in colonial and patriarchal power structures.
Preparation of Tourism Development Plan for Koraput District
Authors: Behera Shiv Prasad
Published: June 2024

Abstract: This article examines the 13 tourist destinations in Koraput, connecting them by the development of a tourism circuit and infrastructure. The district, which is otherwise thought of as a picturesque place located amidst hills, forests, waterfalls, and streams, has poor tourist foot traffic as a result of inadequate basic infrastructure and marketing of the travel destinations. However, the place fails to draw tourists due to the lack of facilities such as drinking water, toilets, accommodation, amusement, or security. The quality of the roads leading to popular tourist spots like Gupteswar, the Gulumi and Duduma waterfalls, the state's highest mountain Deomali, and the little hilltop settlement Maliguda shows how little effort has been put into promoting tourism in Koraput. In contrast, Araku valley in Andhra Pradesh is a tourist destination. Also, there has been an increase in the inflow of foreign tourists from 1,169 in 2015-16 to 1,500 in 2016-17, It shows that although there are no proper services available, still tourist footfall is increasing, but these numbers can be increased if these centres would be developed properly having all necessary services available for tourist.

Wetlands, as part of ecological technology commonly applied in wastewater treatment, are an innovative solution in environmental protection and restoration. Floating Treatment Wetland Systems (FTWs) are a new concept in wastewater treatment using macrophytes rooted in aquatic plants modified as floating systems. Use of a local aquatic plant that is often found and thrives as a weed in rice fields throughout Aceh, namely Actinoscirpusgrossus. Variables varied according to plant height, pond I 90cm – 150cm, pond II 50cm – 90cm and pond III control without plants, influent and effluent were analyzed every two weeks for 18 weeks with 9 analytical sampling times. The results of the domestic wastewater experimental parameter test showed that the average degradation efficiency (%DE) was pH 6.92, total suspended solid (TSS): 98.28%, biological oxygen demand (BOD): 97.77% and chemical oxygen demand (COD): 98.30%, very significant results. The management process of regularly cutting plants is an important part for the Actinoscirpusgrossus aquatic plant to achieve optimum results in processing wastewater, namely for 112 days with a maximum plant growth height of 165cm and 173cm for the two variations of the experimental ponds.
Stereotype of the Devil: SATANIC PANIC
Authors: Jakub Pavlík
Published: June 2024

A visual study/moodboard/presentation of a certain conspiratorial and often delusional stereotype of the character of the devil in the context of what was known as "SATANIC PANIC" in the era of 80's and early 90's in the US.

Even though many of these associations come mainly from the western world, they have been more or less understood and recognized as "devilish" across the world and in the visual culture.

There is a certain stereotype about calling something "SATANIC". Labeling things, activities, clothing, art, products, people etc. as "devil worshipping" often isnt connected to any kind of worship what so ever.

There is this re-accuring act of calling out something as "Satanic" often snowballing the situation into an idea of an active threat, thats dangerous to the public.

The "SATANIC PANIC" era lead to over a 12,000 unsubstantiated cases of these so called "Satanic practices" and many people ended up in jail because of it.

This Satanic labeling has become a parcipatory missinformation quest.
Pride and Prejudice: What Influences Australians’ Attitudes towards Changing the Date of Australia Day?
Authors: Mortimer-Royle Eliza , Webb Stephanie , McLinton Sarven , Watkins Michael , Clark Yvonne
Published: June 2024

Australia Day, celebrated on January 26, is rooted in Australia’s
colonial history and causes pain for many of Australia’s First Peoples.
This study was the first to investigate predictors of Australians’
attitudes towards the date, whilst exploring whether intervention may
improve attitudes towards a date-change. An Australian community sample
( N=559) were recruited through social media for an anonymous survey.
Participants indicated their support for date-change, and responded to a
variety of demographic (e.g., Age) and sociodemographic (e.g., Racism)
questions, then being randomly allocated to an intervention statement,
indicating their final attitudes post-intervention. Findings suggest
sociodemographic factors were more important predictors than
demographics, with Racism ( β =.50***), Traditionalism ( β
=.18**), Patriotism ( β =.13*) and Age ( β =.10*)
significantly predicting participants’ date-change resistance. Racism
demonstrated the most predictive strength, underscoring the importance
of a date-change, with those open to change often identifying any
alternative date should not offend First Peoples. In addition,
intervention produced significant improvement in participants’
date-change attitudes, among those able to become more open to a
date-change; however, differences were not present between intervention
conditions. This illuminates the factors predicting Australians’
attitudes towards Australia Day, whilst demonstrating a potential path
towards date-change through intervention.

Implementing a near real-time patient experience feedback process in inpatient rehabilitation: mixed-methods process evaluation informed by the Normalization Process Theory
Authors: Jesus Tiago Silva , Struhar Jan , T Walters , K Gracz , M Sheth , A Fernandez , C Lopez
Published: June 2024

Purpose: Near real-time patient experience feedback (NRTPEF)
can enable patient-centric quality improvement. We 1) assess the
utility, feasibility, and acceptability of implementing a new NRTPEF,
perceived by patients and providers; and 2) understand how the NRTPEF
became embedded into routine provider practices. Materials and
Methods: Mixed methods process evaluation of the 8-month implementation
of an innovative NRTPEF in an inpatient rehabilitation unit, using
interviews and focus groups with all the service-unit leaders and
interviews with a randomized sample of patients. Beyond descriptive
statistics and content analysis, the Normalization Process Theory (NPT)
informed a framework analysis. Results: Patients and
service-unit leaders perceived high utility in the NRTPEF (median: 9 for
both; 0-10 scale) and qualitative comments emphasized the value of
providing/obtaining timely feedback. The system was found feasible and
acceptable for patients (median: 9.5), but with an improvement margin
for providers (median: 7.3). Suggestions include strengthening the
data-relay format. Even in the pilot form, providers found the NRTPEF
became embedded into practice (median 10; average: 8.6). The
NPT-informed analysis shows how providers saw differential value,
engaged with, and used the patient feedback into reconfigured practices.
Conclusion: An innovative NRTPEF was found useful, feasible and
acceptable, but with refinement opportunities before scale-up.
High-resolution three-dimensional micro-computed tomography assessment of micro-architectural patterns in non-adults with cribra orbitalia : correlation between macro- and micro-scale bone features

Published: June 2024

Skeletal porous lesions such as cribra orbitalia (CO) have long
been of interest to bioanthropologists worldwide, mainly due to their
high prevalence in osteological material. Previous studies considered CO
as an external morphological manifestation, and therefore, research has
mainly focused on visible (macroscopic) CO patterns. However, the
understanding of CO-induced micro-scale bone changes is still scarce.
Therefore, here we performed high-resolution micro-computed tomography
imaging to investigate three-dimensional CO-induced micro-architectural
patterns in non-adults, with a particular focus on the correlation
between macroscopic and micro-architectural orbital features. Cortical
and trabecular micro-architectural changes in the orbital roof were
analyzed in non-adults up to 15 years of age, using orbital roof samples
with and without macroscopic traces of CO (n=28). A widely accepted
five-grade macroscopic CO scoring system was applied to analyze CO
severity. Areas affected with CO (area 1) and areas without macroscopic
CO traces (area 2) were analyzed separately. The conducted
high-resolution analysis showed that cortical and trabecular
micro-architecture varied with CO presence, lesion severity (CO grade),
and the analyzed area. Inter-grade comparisons suggested that most of
the analyzed micro-architectural parameters were not significantly
different between adjacent CO grades. Based on the micro-architectural
evaluation of areas 1 and 2, the porous lesions were much more extensive
than revealed by gross examination. Our analysis also revealed that
micro-architectural differences were particularly pronounced in younger
non-adults. Taken together, the macroscopic examination of CO appears to
reflect only the tip of the iceberg, as the micro-architectural
changes are much larger than macroscopically identified.
To understand the elusive: how to avoid the disappearance of a species at the edge of its continuous range? - the example of the black grouse.

Galliformes are one of the most rapidly declining groups of bird species
in Europe. The black grouse belongs to species closely related to the
types of habitats that are disappearing due to environmental changes
caused by man, climate crisis, and an increase in the number of predator
species. While the populations of this species in Northern and
North-Eastern Europe are still relatively stable, in Central and Western
Europe the black grouse is declining very quickly. For example, in
Poland there has been an approximately 100-fold decrease in its
population over the last 50 years. However, there is a difference
between the rate of decline in black grouse numbers in Central European
lowlands and mountain refuges - e.g. the Alps and the Carpathians. The
European mountains, still offering habitats shaped by relatively severe
climate, may soon be the only type of habitat for this species to
survive in this part of the continent. Our study aimed to indicate the
main environmental factors determining the occurrence of the species in
a mountain refuge, on the southwestern border of this species’
continuous range. Based on a comprehensive model containing data on land
cover by vegetation, topography, and human disturbance, we assessed
environmental factors that shape the probability of black grouse
occurrence in one of its last refuges in Europe. Our results reveal a
trend for black grouse to prefer habitats of an early succession stage,
and those can only persist in specific climatic conditions, or thanks to
active protection. Detailed knowledge of the habitat choice of an
endangered species is valuable data necessary to avoid the fragmentation
of remaining patches of its habitat, to assess the state of the
environment in times of climate crisis, and to protect its features that
ensure and increase the survival of vulnerable species, such as black
grouse.
Analysis of Steady-State Operation of Active Distribution Network under Uncertain Conditions
Authors: ruijin Zhu
Published: June 2024

Recently, distributed generators (DGs) have been widely integrated into
distribution network, so that the distribution network is gradually
transforming into an active distribution network (ADN). Due to the
influence of meteorological conditions, the output of DGs has high
uncertainty. At the same time, considering the increasing variety of
loads in ADNs, the uncertainty of load demand of user side is also
increasing. In order to fully consider the uncertainty of measurement
and quantitatively evaluate the operational status, this paper proposes
a steady-state analysis method for ADNs under uncertain conditions.
Firstly, this paper proposes a steady-state analysis method including
power flow analysis model and evaluation indicators for the operation
status from the perspectives of node and network. Secondly, the
uncertainty factors are elaborated from three aspects: sources, impact
on evaluation index and impact on scheduling. The evaluation indicators
considering uncertain conditions, the impact on system security and
scheduling of network are further discussed. Finally, through the
simulation analysis of the modified IEEE 33-node test system, The
effectiveness of the proposed method are verified.

The experiments conducted in this work aimed at studying and developing a Fe-Cu-Ni-Sn-WC-based alloy, with different additions of Boron Carbide. The production of this metallic matrix is intended for the manufacturing of beads, to be used in diamond wires for cutting ornamental rocks. Five compositions were used for the investigation: samples with 2% B4C, 4% B4C, 5% B4C, 8% B4C, and 10% B4C. Initially, rectangular geometry composites were obtained via hot pressing, and then sintered under the same temperature conditions (800°C) and pressure (34MPa). The obtained segments reached approximately 18.00 mm in length, with widths between 12.80 mm and 15.20 mm, and a height of 3.00 mm. The process of obtaining the density of the samples involved using the Archimedes' method, which consists of submerging the sample in a liquid of known density and measuring the amount of displaced liquid. The density of the sample is then calculated by the ratio of its mass to the volume of displaced liquid. This method is particularly useful for determining the density of irregular or porous solid materials, such as the mentioned composites.The conducted studies serve as a basis for the development of new research aimed at the production of diamond matrices for use in cutting tools.
