Coronary physiology – the news from the last year
Authors: Gatzov Plamen
Published: July 2023

The myocardial blood supply changes, leading to myocardial ischemia deserve deep understanding. They could be on different levels: epicardial arteries, microcirculation or both. Along with the anatomical findings, the functional assessment of coronary vessels is a key moment in making the decision for the type of treatment and the need for coronary revascularization. Together with the established methods for functional assessment of coronary circulation, new technologies nowadays have been applied in the clinical practice. The trends for future development are methods not using myocardial hyperemia, an attempt for functional assessment on the basis of invasive on noninvasive imaging technics and stronger attention to the microcirculatory dysfunction. The new achievements in that direction are on the focus of the current review.

Published: July 2023

A solid basis to address the conservation challenges of amphibians requires an increased knowledge on their natural history and biology. Recent data on reproductive modes in amphibians suggest that they are much more complex and variable than previously thought but understudied. However, detailed information on the reproductive history is especially important to fill the current knowledge gaps. Following recent taxonomic changes in Ranitomeya variabilis, information about captive-breeding management, image-based measurements of total length and surface area of the silhouette for individuals from embryonic to metamorphic development, and detailed larval staging for captive-bred specimens are provided from French Guiana. The development of R. variabilis from the stage eight (Gosner 1960) through metamorphosis took 79 to 91 days (n = 6) with a survival rate of 46%. The developmental stages largely matched those of the generalized staging system of Gosner (1960), with differences in the stages when labia and teeth differentiation and atrophy of the oral apparatus occurred. Compared with other studies the total length of R. variabilis tadpoles was greater at given stages than those of R. variabilis from a Peruvian population and those of the sister species, R. amazonica. Other studies concerning growth curves based on surface area data revealed that R. variabilis tadpoles at peak size were larger than those of R. amazonica, R. imitator, R. reticulata, R. sirensis, and R. vanzolinii, but smaller than R. benedicta. Our results represent the first embryonic and larval staging for R. variabilis, and detailed information is provided on their initial life phases. These data may facilitate the identification of R. variabilis tadpoles in the wild, as well helping to clarify the biogeographical distribution and taxonomic arrangement of the species. In addition, knowledge is added to the captive-breeding methodology for the species.
Beyond the Core Content Framework: Using Experiential Learning to Develop Agentic, Creative and Reflexive Student Teachers
Authors: Egan-Simon Daryn
Published: July 2023

In 2019, the Department for Education introduced the core content framework (CCF) in initial education in England. The framework, which has been criticised for being heavily shaped by research from cognitive science, has, inadvertently, become the baseline curriculum for initial teacher
education. This article explores how experiential learning is being used on a history PGCE course to move beyond the limitations of the CCF and offer student teachers a mode of professional learning that is foregrounded in creativity and critical reflexivity.
Reclaiming Professionalism in Further Education
Authors: Playfair Eddie
Published: July 2023

Further education (FE) is both the most diverse and the most misunderstood sector in English education. FE colleges are sites of social and economic inclusion and personal and collective transformation, offering routes to citizenship, employment and lifelong learning. But the sustained
funding squeeze over the last decade means that FE is also in crisis, with its staff paying the price with their pay and conditions. FE teacher education reflects both the possibilities and the challenges facing the sector. It is rich in commitment and opportunity, and also fragmented and
insufficient. Starting with a personal account of becoming a secondary school teacher and then 'finding' FE, this article touches on some of the current challenges of FE teacher education and looks forward to a better future.

Authors: Killam Laura , Luctkar-Flude Marian , Tyerman Jane
Published: July 2023

Background:

Nurses need to recognize how intersectionality shapes the experiences of individuals and families navigating complex health systems. Guided reflection on complex social justice issues serves as an approach to move beyond simply understanding social determinants of health toward shaping core professional values of developing nurses to promote lasting change.

Method:

Third-year Canadian undergraduate prelicensure nursing students co-created assignment expectations, completed online modules, and submitted initial reflections before class in a mandatory social justice course. In-class debriefing was based on students' reflections and cofacilitated by subject matter experts. Students completed a final reflection that focused on advocating for social change.

Results:

Student feedback, reflections, and grades as well as faculty observations support the success of this interactive student-centered approach.

Conclusion:

A flexible approach to debriefing modular content informed by universal design for learning and simulation theory enables nurse educators to promote in-depth, meaningful, and lasting student learning.

Some stochastic orderings of multivariate skew-normal random vectors
Authors: Li Xueyan , Yin Chuancun
Published: July 2023

In this paper, we investigate some multivariate integral stochastic orderings of skew-normal random vectors. We derive the results of the sufficient and/or necessary conditions by applying an identity for $ Ef({\mathbf Y})-Ef({\mathbf X}) $, where $ {\mathbf X} $ and $ {\mathbf Y} $ are multivariate skew-normal random vectors, $ f $ satisfies some weak regularity condition. The integral orders considered here are the componentwise convex, copositive, completely-positive orderings and their corresponding increasing ones as well as linear forms of stochastic orderings, which play a vital role in transforming the unmanageable multivariate components into an easy-to-handle univariate variable.

Published: July 2023

Depression and suicidality are significant challenges faced by cancer patients, particularly those in advanced stages of the disease or nearing the end of life. Conventional antidepressant therapies often have limited effectiveness or delayed onset of action, making the exploration of alternative treatments crucial. The use of ketamine as a potential treatment for depression and suicidality in cancer and terminal patients has gained considerable attention in recent years. This review article aims to provide a comprehensive analysis of the current data regarding the efficacy and safety of ketamine in this specific population. This review presents an overview of clinical trials and case studies investigating the use of ketamine in this population. It explores the effectiveness of ketamine as a standalone treatment or in combination with other interventions. Furthermore, the article addresses the limitations and future directions of research in this field. It highlights the need for larger, well-controlled studies with long-term follow-up to establish the efficacy, safety and optimal treatment parameters of ketamine for depression and suicidality in palliative care.

Des circassien·ne·s périphériques aux prises avec la globalisation: Trajectoires transnationales et controverses esthétique périphériques aux prises avec la globalisation
Authors: Dupuy Aurore
Published: July 2023

À partir d’une enquête ethnographique au long cours, cet article étudie l’insertion de circassiens issus d’un espace périphérique, le Chili, sur le marché du cirque global, avec ses effets sur les modes de vie et les esthétiques. L’étude de deux trajectoires transnationales met en lumière les stratégies pour exister en marge ou au sein de cirques hégémoniques depuis un espace subalterne, avec un focus sur les circulations entre le Chili et la France. Deux grandes tendances se dessinent et s’affrontent. La première s’inspire du cirque contemporain « artifié » qui s’exporte depuis la France. Il est proposé de considérer la seconde comme un cirque cosmopolite insurgé, à l’inspiration des épistémologies du Sud et de l’anthropologie post-coloniale. Les assises sociales, éthiques et politiques de ces controverses esthétiques sont ainsi mises au jour, révélant des processus d’exclusion, de transfiguration, d’altérisation et d’invention en lien avec les hiérarchies globales.Based on a long-term ethnographic inquiry, this article studies the integration of circus artists from Chile, a peripheral space, into the lifestyle and aesthetics of the global circus market. An analysis of two transnational trajectories, with a particular focus upon circulations between Chile and France, reveals strategies for existing in either the margins or at the center of hegemonic circus companies when coming from a subaltern space. Two overarching trends emerge and clash. The first is the French export of contemporary circus, which has gone through a certain process of “artification.” I propose that the second be considered a rebel cosmopolitan circus, inspired by epistemologies from the South and post-colonial anthropology. The social foundations, ethics, and politics of these controversial aesthetics are hereby brought up to date to reveal processes of exclusion, transfiguration, othering and invention in relation to global hierarchies.
SEGAN-BASED LESION SEGMENTATION AND OPTIMIZED RideNN FOR DIABETIC RETINOPATHY CLASSIFICATION
Authors: Sagvekar Vidya , Joshi Manjusha
Published: July 2023

The most significant issue with diabetes is diabetic retinopathy (DR), which is the primary cause of blindness. DR typically develops no symptoms at the beginning of the disease, thus numerous physical examinations, including pupil dilation and a visual activity test, are necessary for DR identification. Due to the differences and challenges of DR, it is more challenging to identify it during the manual assessment. For DR patients, visual loss is prevented thanks to early detection and accurate therapy. Therefore, it is even more necessary to classify the severity levels of DR in order to provide a successful course of treatment. This study develops a deep learning method based on chronological rider sea lion optimization (CRSLO) for the classification of DR. The segmentation process divides the image into multiple subgroups, which is necessary for the appropriate detection and classification procedure. For the efficient identification of DR and classification of DR severity, the deep learning approach is used. Additionally, the CRSLO scheme is used to train the deep learning technique to achieve higher performance. With respect to testing accuracy, sensitivity, and specificity of 0.9218, 0.9304 and 0.9154, the newly introduced CRSLO-based deep learning approach outperformed other existing DR classification techniques like convolutional neural networks (CNNs), deep convolutional neural network (DCNN), synergic deep learning (SDL), HPTI-V4 and DR[Formula: see text]GRADUATE. The Speech Enhancement Generative Adversarial Network (SEGAN) model in use also produced increased segmentation accuracy of 0.90300.

Published: July 2023

In this paper, we investigate the probability of the charge transfer interaction process from Cu metal to P6 molecule systems using charge transfer rate calculations. The charge transfer rate from donor Cu metal to an acceptor P6 molecule dye is presented with reorientation energy, electronic drive force, and barrier height emphasis on the eﬀects of transfer processes in the Cu/P6 system. Charge transfer flow probability from Cu metal contacts to P6 dye molecule has recently been considered within the perturbation theory method, where the charge transfer rates have been found to be affected by strength coupling and reorientation energy. The charge transfer could be occurred even at large reorientation energy, less driving force energy, and low potential barrier. It requires to reorientation the donor to acceptor energy levels to start the charge transfer. It has been found that the rate of charge transfer processes enhance the flow rate yield of the transfer cross interface dependent on the potential barrier.
Comparison of Carrier Deflection between MAG-TFET and MAG-FinFET
Authors: Boonlua Thanet , Poyai Amporn , Phetchakul Toempong
Published: July 2023

This paper is a comparison of the carrier deflection mechanism of a new magnetic sensor structure between the tunneling Field Effect Transistor (TFET) structure and the FinFET structures so-called MAG-TFET and MAG-FinFET.The device relies on carrier deflection from magnetically induced forces. The MAG-TFET current is caused by electron tunneling and drifting through the bulk under gate while the MAG-FinFET current is caused by the drift channel carrier from the inversion layer induced by gate voltages and there is also a bulk current beneath the substrate. The carrier deflection of the device is due to the current in the induced channel and current in the bulk. From the results, carrier deflection in the induced channel is better than in the bulk. The device sensitivity depends on the proportion of these two currents.

Published: July 2023

The introduction of plastic materials has revolutionised our society. However, excessive use of traditional, non-biodegradable plastic materials, especially for packaging applications, has created many environmental issues. During the past few decades, many biodegradable polymers, bio-based and petroleum-based, have been developed to address the above problem. Several research has been carried out on various biodegradable polymer blends and composites. However, their widespread application is still limited. This paper gives an overview and progress made on biodegradable polymers for flexible packaging applications, a critical analysis of their performance characteristics and recommendations on priority areas for further research. This Paper shows that, among the polyesters, though PHAs is most attractive concerning biodegradability, its low elongation at break, narrow processing temperature and high production cost limit their use for flexible packaging application. For flexible packaging applications, PBS (Polybutylene succinate) is better than PLA (Polylactic acid) and PHAs (Polyhydroxyalkonates), considering thermal characteristics and tensile elongation. In addition, PBS is biodegradable in compost, soil, lake and seawater, though its rate of biodegradation is reported to be slower compared to PHAs.

Authors: Sapri Muh.S. , Mashuri Mashuri
Published: July 2023

Research on the mechanical thermal stability of micro-porous carbon-based micro composites with marine paint matrices has been carried out. Microporous carbon has the property of absorbing radar waves so it is very interesting to research and develop into a microwave shielding material synthesized from coconut shell (cocoa nucifera) by carbonization process at 600°C for 45 minutes. The molecular structure and phases of micro porous carbon were characterized using Fourier Transform Infrared (FTIR) and X-Ray Diffraction (XRD) with the results confirmed of micro carbon with reduced graphene oxide (rGO) phase. Furthermore, micro-composites made from porous micro carbon with marine paint as a binder were made using the wet mixing-casting method. Mechanical thermal testing was carried out by means of a shear test at a temperature range of 30 – 70°C using a Dynamics Mechanical Analysis (DMA) tool. The test results showed that the value of the storage modulus of porous micro carbon composites was 1.653 MPa, 10.196 MPa, 13.068 MPa, 118.567 MPa, respectively. The value of the composite storage modulus increases with increasing concentration of porous micro carbon with an optimum value of mechanical thermal stability at a composition of 70:30 %wt. The results of mechanical thermal testing showed that porous micro carbon with rGO phase from coconut shells has the potential to be used as an anti-radar shielding material. 068 MPa, 118.567 MPa.

Published: July 2023

A Haar cascade classifier is a machine learning (ML) algorithm used for object detection. In this paper, the Haar algorithm is introduced in the context of a non-destructive evaluation of fibrereinforced composite (FRC) structures. The Haar learning model is used for flaw identification from thermal images. Thermal images are created from cross-ply (CP) carbon fibre-reinforced laminates with flat-bottomed holes (6–10 mm) of different depths from the surface (0.5–1.5 mm). After training is complete, the model successfully detects similar artificial flaws in previously unseen thermal images. In doing so, the feasibility of Haar classifiers for automatic evaluation of FRCs is established.

Published: July 2023

The hydrothermal synthesis of amikacin modified carbon dots-doped nitrogen and zinc- (N,Zn-CDs) and its capacity to detect Escherichia coli (E. coli) have been investigated. Amikacin is one of the aminoglycoside antibiotics utilized in this study as a ligand of N,Zn-CDs to attach to E. coli. This study also examined the effect of nitrogen (N) and zinc (Zn) dopant content on enhancing N,Zn-CDs fluorescence emission intensity. N,Zn-CDs were characterized using a spectrofluorometer, UV-Vis spectrophotometer, FTIR, EDX, XRD, and TEM, which revealed their amorphous nature and average particle size of 3 nm. The emergence of bond vibrations of C=O, CN, and ZnO indicates the success of N and Zn dopants. Amikacin was then included in the structure of N,Zn-CDs to enhance their ability to detect E. coli. The maximum fluorescence intensity was seen in N,Zn-CDs with a mole ratio of 1:4:4 mmol for the carbon precursor, N, and Zn dopants, and a volume of 0.1 mL amikacin. Based on the fluorescence response of amikacin-modified N,Zn-CDs against E. coli, a limit of detection 1,490 cfu mL-1 was obtained.

Published: July 2023

Cerebral Aspergillosis (CA) is an opportunistic fungal infection that usually affects immunocompromised hosts. A man was admitted for loss of consciousness and aphasia. Computed Tomography (CT) scan showed a left cerebral frontal lesion. Nasal swab showed hyphae of Aspergillus spp.; isavuconazole was started. Lumbar Puncture (LP) tested positive for galactomannan (index 1.9), and Aspergillus fumigatus grew on the Cerebrospinal Fluid (CSF) culture. Unfortunately, a new episode of fever and a general deterioration then ensued up to the death. In immunocompetent patients as well, chronic fungal rhinosinusitis deserves attention due to its potential for rapid evolution to Central Nervous System (CNS) involvement.

Motor Dysfunction of Gastric Antral Smooth Muscle in Diabetic Rats: Contribution of ATP-Dependent Potassium Channels
Authors: Khoshavi Najafabadi Fatameh , Sadraei Hassan , Mehranfard Nasrin , Ghasemi Maedeh
Published: July 2023

Background:

The goal of the current research was to further elucidate the role of adenosine triphosphate (ATP)-sensitive potassium (KATP) channels in the motility and contractility force of gastric smooth muscle of diabetic rats.

Materials and Methods:

Male Wistar rats (190–230 g) were grouped into control and streptozotocin (STZ)-induced diabetes (55 mg/kg) rats. Thirty days later, gastric muscle contractility was measured using a myograph and a force transducer of antral segments immersed in a tissue bath. Gastric emptying response was measured through feeding of standard pellet. Furthermore, the expression of KATP channel subunits in antral smooth muscle was determined by western blot technique.

Results:

The amplitude of KCl-evoked twitch contractions of diabetic antral strips was about 25% more than control (P < 0.05). Application of minoxidil, a KATP channel opener, dose dependently decreased the force of twitch contractions in both normal and diabetic antral strips. Application of 10 μM glibenclamide, a KATP channel blocker, did not antagonize the minoxidil-induced relaxation of antral strips. Diabetic gastric emptying was faster than normal, although not significant. Despite the relaxant effect of minoxidil on gastric emptying rate in normal rats (P < 0.05), this effect was not observed in diabetic rats. Also, glibenclamide increased gastric emptying and antagonized minoxidil-induced relaxation in normal rats (P < 0.05). Furthermore, the expression of KATP Kir6.1 and SUR2B subunits was substantially reduced in antral smooth muscle in diabetic condition (P < 0.01).

Conclusion:

These results propose that KATP channels may contribute to the development of gastric motility disorders in diabetes.

Authors: Baro Baneswar , Saloi Ritu , Bora Bhabajyoti , Rabha Gunamani
Published: July 2023

Background:

Anatomical knowledge is an integral component of medical education. As there is little consensus over the best teaching methods, teachers may use a variety of teaching aids to help students understand a particular topic.

Aims and Objectives:

The aims and objectives of the study were to evaluate the impact of three-dimensional (3D) models as a teaching tool for the pelvis.

Subjects and Methods:

We conducted a study among 100 phase 1 MBBS students at a tertiary medical college to assess their level of understanding of pelvic anatomy from a teaching perspective. 3D models were constructed and used as teaching tools. Participants were evaluated using a Likert scale and knowledge-based tests, such as multiple-choice questions and identification questions.

Results:

The results showed that the teaching tool used significantly (P < 0.05) improved the understanding of the topic, and most of the students strongly agreed that the teaching was informative (71.4%) and interesting (73.7%). A total of 76.4% of students agreed that they could easily take notes. All students (100%) agreed that the teaching tool used was clear, audible, understandable, well organized, advancing their understanding of the subject, and helpful for revision and memory retention.

Conclusions:

The results suggest that using physical 3D models as a teaching tool improve the overall understanding of the pelvic region. However, further studies are required to assess the long-term impact of the 3D model as a teaching tool.

Published: July 2023

The fatty acid composition, cholesterol and fat-soluble vitamin levels in the muscle tissue of economically important freshwater fish Luciobarbus esocinus, Capoeta trutta and Luciobarbus mystaceus were investigated. The analysis of fatty acid methyl esters was carried out by gas chromatography, and cholesterol and fat-soluble vitamin amounts were determined by high-performance liquid chromatography (HPLC). Among polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA, C20:5n-3) was found to be higher in C. trutta (14.84%) compared to the other fish species, while the highest amount of docosahexanoic acid (DHA, C22:6n-3) was determined in L. mystaceus (20.43%). While the maximum amount of total n-3/n-6 PUFA ratio was determined for C. trutta with 4.64%, it was determined that the sum of EPA and DHA from n-3 series fatty acids was higher in C. trutta with 31.74%. When the fat-soluble vitamin and cholesterol levels of the species were compared, it was found that the difference between the amounts of δ-tocopherol, α-tocopherol, D3, K1, K2 and cholesterol did not differ between the species. In conclusion, L. esocinus, C. trutta and L. mystaceus living in the Keban Dam Lake are valuable food source in terms of fatty acids, vitamin and cholesterol. It is thought that the findings of this study is beneficial for researchers and fish consumers.
Only Survivors Grow – Effects of Predation on Stocked Juvenile Common Carp (Cyprinus carpio Linnaeus, 1758) in a Stagnant Waterbody
Authors: Sturmberger Valentin , Unfer Günther , Friedrich Thomas
Published: July 2023

This study aims to investigate the suitability of an entirely stocking-based fisheries management strategy to establish a self-sustaining carp population in two water bodies within the Danube catchment east of Vienna. The assessment was generally based on two factors: the effect of predation on juvenile carp`s mortality and potential differences in the growing performance of different age classes. The investigation on predation effects showed, that after one year ~541 of initially 1000 stocked K1 survived in the water body with decreased pressure of predation, while there was no evidence of surviving stocked juveniles in the water body with increased pressure. Regarding the growth-rate, the stocked K1 showed the overall steepest growth curve compared both to the stocked K2 cohort and selected wild populations. After five years the younger stocked cohorts ML was even higher than the older cohorts one at the same age, although the stocked K2 had by far a larger initial TL.
Our results showed that predation can massively impact the mortality rate of stocked K1 juveniles and thus the success of fisheries management strategies. Moreover, it demonstrated the benefits of stocking fish in early life stages regarding a best possible adaptation to the given environmental conditions.

Тогда рационально тривиальные 0-циклы на $X$ образуют абсолютно простой и существенный подмодуль в $Z_0(X)$.

e-Sys Electric Axle: Electrification Solution for Commercial
Vehicles
Authors: Beraldo Carlos Eduardo , Pereira Cassiano , Noro Eugenio , Botelho Rogério , Mauri Tainan
Published: July 2023

With the increase in demand for energy sustainability projects over the last few
years, the Brazilian commercial vehicle industry was guided to develop projects
based on ESG policies. Aligned with this need, an initiative that ended up
becoming a reality was the “e-Sys” electrification solution, by the company
Suspensys. This solution includes a power source (battery), an e-powertrain
(motors, inverters and drive axle) and an intelligent control system (VCU with
embedded code and sensors). The main motivational drive was the hybridization of
semi-trailers, in order to generate a reduction in fuel consumption in cargo
transport in Brazil, in addition to the consequent reduction in the emission of
particles into the environment and promoting the safety of the operation. It was
also adopted, as a premise of the project, that the electrification system was
totally independent of the truck’s electronic system (stand alone system), in
order to facilitate the operation of the fleet owner. The solutions went through
the four main phases of an automotive development: PoC, MVP, Fleetseeding
(customer experimentation) and SoP. All of these were supported by various
safety, functionality, performance and endurance tests, unrestricted for product
validation in terms of robustness and, above all, safety. The regenerative brake
system also proved to be one of the additional benefits within the product’s
payback chain, given the reduced need for maintenance. During development, it
was identified that the application of the electric axle would not be restricted
to the hybridization of semi-trailers due to the synergy with other models of
commercial vehicles, both in the helper/hybrid mode (in which the system acts as
a support, helping the main system truck tractor), and in full electric mode (in
which the system acts as the vehicle’s only tractor). In addition to
representing the entry of Suspensys into the electromobility market, e-Sys also
paved the way for the construction of the first Brazilian battery assembly plant
with 100% Brazilian capital and know-how, within the Caxias do Sul manufacturing
park.

Abstract
5 - Role Duality among School-age Children Participating in Farming in Some Villages in Kwara State, Nigeria
Authors: Adisa Rashid S. , Adekunle Oluwasegun A.
Published: July 2023

The paper examines rural children’s role duality as school pupils and farm par- ticipants. Multi-stage cluster random sampling was used to elicit data from 229 respondents aged between five and sixteen years. It was found that 44 per cent of the respondents were simultaneously schooling and farming, while the re- maining were only either in school or farming. Using eight common farm activi- ties, a coefficient of farm participation (cfp) was computed, while another eight agricultural innovations were used to compute agricultural innovation aware- ness index (awi) for each respondent. It was found that no significant difference existed in farm participation levels of respondents attending school and those that were not, while a significant difference in innovation awareness (awi) ex- isted in favour of respondents in school. Parental influence, peer group and school farms were also found to be significantly related to respondents’ partici- pation in agriculture. It is thus imperative to keep rural children in school even as they are engaged in farming activities.

Variación de la línea de costa en playas de Santiago de Cuba
Authors: Castellanos González Juan Ramón , Velázquez Labrada Yunior Ramón , Pérez Benitez Mayelin
Published: July 2023

El artículo tiene como objetivo determinar la variación de la línea de costa, tanto por erosión como acreción, en ocho playas del municipio Santiago de Cuba, en un promedio de 14 años. Se tuvo en cuenta la fotointerpretación y digitalización de la línea costera, a partir de imágenes satelitales Sentinel y el empleo del software QuantumGIS 3.22. Los resultados demostraron una variación total de la línea de costa de -14.06 m en el período de estudio, para un promedio -1.76m según el total de playas analizadas. De manera particular, la erosión costera, alcanzó una sumatoria de -39.08m. La tasa de erosión promedio se comportó en -0.58 m/año. Las playas más afectadas fueron Casonal, Baconao, Verraco y Juraguá con tasas anuales de -1.61m en el primer caso, -0.7 m en el segundo y -0.49m en los restantes. Por otra parte, la variación por acreción se comportó en 10.96 m durante todo el período, con un promedio de 1.37m atendiendo al total de playas estudiadas y una tasa de 0.33 m/año. Estuvo presente en seis playas. Los valores más elevados de tasa anual promedio se muestran en Baconao, Cazonal y Verraco con 0.7m, 0.51m y 0.49m respectivamente. Lo anterior evidencia las modificaciones en la línea de costa, el incremento progresivo de dicha tasa y la incidencia directa de factores naturales y antrópicos.
Manejo integrado de pastos marinos en el sector Aserradero-Chivirico, Santiago de Cuba
Authors: Blanco Ojeda Josefina , Velázquez Labrada Yunior Ramón , Tamayo Fonseca Jorge Antonio
Published: July 2023

En la investigación se diseñó un programa de manejo integrado para los pastos marinos del sector costero Aserradero- Chivirico, municipio Guamá, provincia Santiago de Cuba. En correspondencia con el enfoque de Manejo Integrado de Zonas Costeras, se efectuaron cuatro visitas de trabajo de campo al área de estudio y se realizó el levantamiento de los principales usos y recursos con influencia sobre los pastos marinos. Los resultados demostraron siete problemáticas ambientales que influyen directamente sobre los pastos marinos. Se identificaron 22 actores y cuatro asuntos claves a manejar. El empleo de matrices de uso-uso y uso-recurso arrojaron que el vertimiento de desechos líquidos y sólidos genera el principal conflicto y son fuentes de aporte de sedimentos al mar. El programa de manejo incluyó seis acciones que dan respuesta a los objetivos estratégicos y asuntos claves identificados. Se concluye que la puesta en práctica de dicho programa podría constituir una alternativa para la conservación de los pastos marinos.
Roman Silver Objects from the Ancient Kingdom of Kartli (Caucasian Iberia) in Georgia (Mtskheta, Dedoplis Gora [Kareli district]) – a Lead Isotope Investigation
Authors: Parjanadze Teimuraz , Bode Michael
Published: July 2023

Seven silver objects from antique Georgia, e. g. a raven and a goddess Diana sculpture, have been archaeometallurgically investigated. Six are dated into the 1st century AD and have been found in a burnt down palace at “Dedoplis Gora”. They are all strongly affected by  a fire which was caused by an earthquake in 80 AD. Another object of study is a fragmented silver box of the 3rd century AD, excavated  at Mtskheta, the old capital of the Kingdom of Kartli. All objects come from a time of great political influence from Rome. The  provenance investigation by lead isotope analysis points not only to three different sources in the Roman Empire, the Central Balkans, the Cévennes (Massif Central) in France and the Pangeon Mountains in northern Greece, but also to lead-silver mines in Iran.
Identity and Publishing in Archaeometallurgy
Authors: Sabatini Benjamin , Mödlinger Marianne
Published: July 2023

This paper covers aspect of the gender, education, and current profession of individuals engaged in archaeometallurgy from an anonymous questionnaire submitted by the authors to the ARCH-METALS LISTSERV. While the questionnaire itself was answered by only a fraction of the total list members, and likely excludes a portion that do not subscribe, we believe those that responded are some of the most active individuals in the field and it therefore has value as the first self-reflexive poll of its kind. It allowed the authors to  obtain anonymous information regarding the academic training of practicing archaeometallurgists, and aspects of the review and paper publication preferences in the field. Recommendations for improving publishing and review speed are also discussed based on the questionnaire results and current review literature.
