Corrosion protection of mild steel using nanomaterials coating
Authors: Mohan Prasad , Saravanathamizhan Ramanujam , Thangavelu Perarasu
Published: December 2023

Effectiveness of nanoparticle coatings in preventing corrosion of mild steel metal samples were experimentally determined. TiO2 and ZrO2 nanoparticles coatings were done by brush coating. Different samples were prepared by varying the parameters such as thickness of coatings, concentration of nanoparticles and temperature of heat treatment. Corrosion rate of both uncoated mild steel and coated using TiO2, ZrO2 samples was determined in the corrosive environments of 1M HCl and 3.5 wt% NaCl. From the experiments it was found that the coated mild steel samples prepared at temperature 80oC are more effective than samples prepared at 200 oC. It is observed that TiO2 coatings prepared with ratio 2:0.3, 0.182 mm coating thickness and heat treated at 80oC, and ZrO2 coatings with thickness of 0.185 mm, prepared from nanoparticle paste of 1:0.3 ratios, heat treated at 80 oC, have shown better protection for mild steel in 1M HCl and 3.5% NaCl solutions compared with other TiO2 and ZrO2 coatings.

Published: December 2023

The prediction of boride layer growth kinetics requires the development of a mathematical model. In the present study, two diffusion models (a simple model and an integral method-based model) were proposed to investigate the boriding kinetics of pack-borided AISI H13 steel. These two diffusion models did not consider the effect of boride incubation times of the total boride layer (FeB + Fe2B). The diffusion coefficients of boron in the FeB and Fe2B layers were estimated using the proposed integral method-based model. Additionally, the growth rate constants were determined and the layer thickness was calculated after finding the needed parameters. The results obtained were compared to the experimental ones taken from the work of Nait Abdellah et al.[4] and a good agreement has been noticed. Finally, the mass gain has been calculated for both phases, showing that of FeB increased more compared to that of Fe2B over time.
The right to suspend performance in case of anticipatory breach of contract on international sale of goods
Authors: Zdravković Uroš
Published: December 2023

In this paper, the author analyzes the provisions of the UN Convention on Contracts for the International Sale of Goods (CISG) which regulate the legal remedies available to contracting parties in case of anticipatory breach of contract. Anticipatory or presumed breach of contract implies a situation when one contracting party, on the basis of objective indicators, assumes that the other party will not perform its obligation. In this regard, the CISG provides for two legal remedies available to the contractual party that anticipates the breach of contract: a) to suspend the performance of its obligation, and b) to terminate the contract. This paper specifically analyzes the provisions of Article 71 of the CISG, which governs the right of a contracting party to suspend the performance of its obligation. Article 71 CISG authorizes a seller or a buyer to suspend performance of its obligations under the sales contract if a party is unlikely to receive a substantial part of the counter-performance promised by the other party. The suspending party does not breach the contract if the suspension is rightful. However, if the suspension is not authorized by Article 71 CISG, the suspending party will breach the contract when it fails to perform its obligations. A party may suspend the performance of its obligations if, after the conclusion of the contract, it becomes apparent that the other party will not perform a substantial part of its obligations as a result of a serious deficiency in the party's ability to perform, or the party's creditworthiness, or the party's conduct in preparing to perform or in performing the contract. The right to suspend perfomance under Article 71 CISG is to be distinguished from the right to avoid the contract. Unlike the contract avoidance, which terminates the obligations of the parties, the suspension of contractual obligations recognizes that the contract continues and encourages mutual reassurance that both parties will perform. If the seller has already dispatched the goods, he may prevent the handing over of the goods to the buyer even though the buyer holds a document which entitles him to obtain the goods. This relates only to the rights in the goods as between the buyer and the seller. A party suspending performance, either before or after dispatching the goods, must immediately give notice of suspension to the other party, and must continue with performance if the other party provides adequate assurance of his performance.
The relationship between the prohibition of refoulement and the prohibition of collective expulsion in the context of access to territory: Standards of the European Court of Human Rights and their relevance for the legal system of the Republic of Serbia
Authors: Čučković Bojana
Published: December 2023

This article examines the relationship between the prohibition of refoulement contained in Article 3 of the European Convention on Human Rights and the prohibition of collective expulsion of aliens guaranteed by Article 4 of Protocol No. 4. After identifying common and distinctive elements of the two provisions, the author tests the main hypothesis that the prohibition of refoulement and the prohibition of collective expulsion are separate prohibitions with an independent existence but that they are intertwined in a variety of ways in the specific context of access to territory. The analysis has led to the conclusion that, despite the open questions that remain, the linkage between the two provisions can be used for corrective purposes, particularly in light of the recent lowering of standards by the ECtHR in relation to the prohibition of collective expulsion. It is also suggested that the difference between the positive obligations contained in the two ECHR articles has no significance for the authorities acting on the ground. As the protection afforded by the two prohibitions is complementary , national authorities must ensure that both border practices at and outside the means of legal entry comply with the ECHR standards in relation to both provisions.
Labour law effects of death and loss of legal capacity of an employer acting in the capacity of a natural person
Authors: Dragićević Marija
Published: December 2023

The employer may act in the legal capacity of a natural person or a legal entity. In the former case, the subject of an employment relationship is a natural person per se or a natural person in the capacity of a sole trader or a freelancer. In the latter case, given that a natural person is identified with his/her own enterprise (as they constitute one body), the question arises what happens in the event of a change in the legal status of a natural person as the employer (a holder of a sole proprietorship), which will primarily take place in the event of death or loss of legal capacity. Considering that the labour legislation of the Republic of Serbia does not provide an answer to this question, the author will address this question by seeking answers within the framework of general rules of labour, inheritance, family and company legislation. In that sense, the paper analyzes the effects of death and loss of legal capacity of an employer (a natural person) on the existing employment relations. The author aims to respond to the question whether the employer's death necessarily causes the termination of employment, or whether such employment may be continued by the employer's successors (in which case, it may be considered as the change of employer). In particular, the author focuses on the provisions of the Business Companies Act, which regulate the possibilities to continue conducting the business in the event of the sole trader's death while implicating their shortcomings, unclarities and issues they cause in the interpretation and practical application thereof. In that context, the author examines the legal grounds enabling the successor to take over the sole trader business, the subject matter of such succession, the labour law status of employees, and the possibility for the co-successors' community (a number of natural persons) to act in the capacity of the employer.
Protection of cultural goods in Croatia and Serbia, with reference to restrictions of ownership rights
Authors: Klasiček Dubravka , Nedić Tomislav , Budiša Vlasta
Published: December 2023

In the Article 52 of the Constitution of Croatia, cultural goods are declared as goods of special interest to the Republic of Croatia that enjoy the special protection of the state. Article 69 of the Constitution stipulates that, among other things, the state protects cultural goods as spiritual national values. Article 89 of the Constitution of Serbia determines the obligation of every person to preserve, among other things, cultural heritage as an asset of general interest. The authors believe that something similar exists in most modern legal systems. Various legal subjects own many cultural goods. Still, given their status and the special protection they enjoy, the owners of such goods are subject to certain ownership restrictions and have obligations that owners of most other things do not have. In this paper, the authors will analyze Croatian and Serbian legal acts that regulate the protection of cultural goods with special reference to restrictions of ownership rights over cultural goods in these two countries. There are certain similarities but also some differences in how the protection of cultural goods is regulated in Croatia and Serbia. The types of cultural goods and their protection vary in certain ways, as well as the rights and obligations of owners of cultural goods.

Published: December 2023

Modified metal transfers in MAG welding bring a number of advantages in terms of technology and operation. Likewise, it is possible to apply the same for cladding, where it is necessary to understand the influence of certain parameters. In this paper, the influence of the polarity balance of the AC MIG process on the geometrical characteristics and macrostructure during cladding of S355JR grade steel with 2205 duplex steel wire was investigated by producing three specimens with different current balances. Tests on the geometry of the welded layer as well as on the dilution rate were performed, and results indicating significant changes in geometry as a function of the change in polarity balance.

Published: December 2023

Improvements in brazing technologies are not widely present as in welding technologies. Many artefacts from the encient times show that brazing technologies are in use over 5000 years, what make them older from welding procedures. A long time the brazing was applied on the king courts for making jewels and/or ornamental pieces. For a particular technologies from that time hardly to be said that they are "primitive", because they are founded in application (as we today use to say diffusion welding/brazing procedure), which are nowdays are in use in changed form (by application of a pressure) in production of reliable components from airor cosmic industry. The application of MIG method is known and widely used in welding procedures, almost for steels (both for common structural or stainless) also in numerous non-ferrous metals (aluminium, copper, titanium, etc.), but this method markably less is used for brazing. Here will be shown couple of examples of MIG brazing of some complex structural shapes.

Authors: Đurić Aleksija , Milčić Dragan , Klobčar Damjan , Marković Biljana , Milčić Miodrag
Published: December 2023

Multi-material design was developed as a modern design concept for lightweight structures (Lightweight design - LW) which aims to integrate different types of materials into one structure. The main problem when joining sheets made of different, i.e. dissimilar materials, primarily steel and aluminum alloys, are the different mechanical, physical and chemical properties of the materials being joined. Through this paper, the state of the art will be analyzed when it comes to modern technologies for joining steel and aluminum alloys sheets. The term "modern joining technique" refers to all innovative joining technologies that have been developed or have seen significant application in the last few years.
Investigation of welded joints of 700 MPa grade high strength low alloy steel
Authors: Bulatović Srđan
Published: December 2023

The requirements of economical consumption of energy and raw materials direct steel producers to the production of weldable steels of high strength, and designers and constructors to their application in welded constructions. The use of high strength low alloy steel (HSLA) in metal constructions is increasingly prevalent, primarily due to their forming properties, where weldability is of particular importance. Therefore, over time, a whole series of test procedures has been developed, the aim of which is to better understand the properties of the welded joint of the mentioned materials and to use them more rationally. The analyzed properties, such as tensile testing, impact toughness and hardness, give a broader picture of the welded joints of high strength low alloy steel and their properties and compared with the requirements of international standards in the field of arc welding.

Published: December 2023

More often than not, documentation about making and testing of welded structures does not include visual test reports, or includes such reports which are not in accordance with relevant standards. Welded structure failure is caused by cracks, which typically occur in welded joint defects. Some of these defects can only be detected using visual testing. In addition, visual testing is a reliable method for determining which parts of a welded joint have increased risk of crack initiation, i.e., repair locations during fabrication or exploitation, which also need to be subjected to other non-destructive test methods. In this way, probability of failure is decreased, i.e., welded structure safety is improved. This is of particular importance for pressure equipment. This paper shows the failure of a tank used for storage of liquid oxygen during exploitation. During tank fabrication, a number of defects were made in the welded joint. One of these defects, in the form of a notch, lead to the destruction of the tank after years of exploitation.

This research was motivated by the problem that was found that there were still many students lacking training in writing Arabic, especially in imla'. Therefore, research was carried out on the analysis of word writing errors using the imla' al-masmu' method which aims to describe the forms of errors and the causes of errors in writing Arabic at the student level. The type of this research is a descriptive qualitative approach with analysis applying the Rusydi Ahmad Tha'imah method, divided into three stages, namely three steps, namely error recognition (Ta'rif Al-Khatha'), exposure and error data (Tausif Al-Khata') along with the interpretation and explanation of errors (Tafsir Al-Khata') in the documentation results of Arabic language education students 1 Stambuk 2021 UINSU, totaling 33 documentations. This research collects data by applying methods, namely documentation, observation and interviews. The results of this research show that imla' errors were made 6 times. These types of errors include errors in identifying the sounds of Arabic letters, errors in connecting letters, errors in the use of tanwin, errors in the use of ta' marbutha, errors in the use of mad, errors in writing the hijaiyah form. The factors that cause errors in writing Arabic are the reader's lack of clarity in pronouncing the letters, dictating too quickly and students not really understanding the rules of imla' well
ANÁLISE ESTATÍSTICA DO BRILHO SOLAR NO ESTADO DOACRE ENTRE OS ANOS DE 1991 E 2015 PARA DETERMINAÇÃO DE NORMAIS CLIMATOLÓGICAS PROVISÓRIAS DE INSOLAÇÃO
Authors: Muniz da Silva Helmut
Published: December 2023

No intuito de contribuir com a compreensão sobre a variabilidade temporal da insolação (brilho solar ou horas de sol) e o aprofundamento do tema, o presente trabalho realizou uma análise estatística sobre as médias diárias mensais das horas de sol dos dados diários coletados por estações meteorológicas convencionais do Instituto Nacional de Meteorologia (INMET) para as cidades de Rio Branco, Tarauacá e Cruzeiro do Sul, no estado do Acre, entre os anos de 1991 e 2015 para apresentar Normais Climatológicas Provisórias para o referido parâmetro. Para tanto, foram determinadas as medidas de tendência central, de dispersão, de assimetria e curtose de cada estação, bem como os resultados para os indicadores estatísticos do erro médio (MBE), do desvio médio absoluto (MAD) e do erro médio quadrático (RMSE). Os resultados mostraram que as curvas de insolação média mensal para as três estações demonstraram um comportamento muito semelhante ao longo do ano com disponibilidades do brilho solar com valores maiores no período do inverno local, provavelmente, devido às características do clima local. Foram obtidas ainda correlações lineares entre essas medidas, originando fatores de proporcionalidade e coeficientes de correlações. Finalmente, promoveram-se comparações com os registros descritos por outros autores e com as Normais Climatológicas para os períodos de 1961 a 1990 e de 1981 a 2010. Os resultados mostraram que as curvas de insolação média mensal para as três estações demonstraram um comportamento muito semelhantes ao longo do ano com valores maiores quando comparados com a literatura, bem como para as Normais Provisórias de Insolação.

Os resultados da avaliação de desempenho operacional de Sistemas Fotovoltaicos de Bombeamento podem ser influenciados pelo número de dias de ensaio e pela contribuição da proporção de irradiação difusa (PD) ao longo do ensaio. Diante disso, foram analisados modelos de predição do volume bombeado diário a partir da irradiação global no plano do gerador fotovoltaico, utilizando-se modelagens de regressão linear simples. Para obter os dados para elaboração dos modelos, foram ensaiadas quatro motobombas, duas de 1,5 HP e duas de 2 HP. Para todos os modelos desenvolvidos, a validação estatística foi feita por meio do Coeficiente de Determinação (R2), Valor-p da Análise de Variâncias (ANOVA) e Erro Médio Absoluto Percentual (MAPE). Dessa forma, inicialmente, para determinar-se o número mínimo de dias, desenvolveram-se modelos contendo todas as observações coletadas nas campanhas de medição e modelos contendo apenas seis (6) amostras, considerando apenas PD ≤ 25%. Para as quatro motobombas, as modelagens de regressão desenvolvidas a partir de todas as amostras apresentaram [0,73 ≤ R² ≤ 0,95] e [1,26% ≤ MAPE ≤ 3,84%]; já para os elaborados com menor número de observações, obteve-se [0,89 ≤ R² ≤ 0,97] e [1,51% ≤ MAPE ≤ 2,25%]. Após essa validação do número mínimo de ensaios, realizou-se a análise estatística para modelos construídos com amostras reduzidas, mas diferentes PD’s (até 25%, 30% e 40%), a fim de verificar a influência desta variável sobre a qualidade dos modelos. Para as duas motobombas com dados suficientes, considerando dias com PD ≤ 25%, obteve-se modelagens com [1,51% ≤ MAPE ≤ 1,97%]; para aqueles modelos com PD≤ 30%, verificou-se [2,03% ≤ MAPE ≤ 2,57%] e, para aqueles com PD ≤ 40%, observou-se [3,11% ≤ MAPE ≤ 4,54%]. Portanto, recomenda-se, para ensaios de desempenho de Sistemas Fotovoltaicos de Bombeamento, a realização de, no mínimo, seis (6) dias de testes com PD ≤ 25%.

Probabilistic Soil Liquefaction Assessment: A Case Study for Agartala City in Tripura in North-East India
Authors: Paul Avik , Ghosh Sima , Majumder Priyanka
Published: December 2023

A sudden increase in pore water pressure causes the effective stress to decrease significantly, which in turn causes a loss of shear strength and the subsequent outcome of allowing the soil to behave as a liquid, resulting in soil liquefaction. Agartala, the capital of Tripura, is located in northeastern India, and the entire region is considered seismically active according to the seismic zoning map of India as per IS 1893:2002 (Part 1); the entire region is classified as Zone-V. Significant earthquakes have struck this region, including the 1897 Shillong and 1950 Assam earthquakes. The city is vulnerable to liquefaction due to alluvial soil and a low groundwater table. Several parameters are involved in assessing liquefaction potential in the deterministic method and have different input parameter uncertainties, resulting in inconsistent outcomes. As a result, evaluating liquefaction susceptibility requires a thorough probability approach that considers parameter uncertainty. In this work, the soil liquefaction potential of Agartala City is assessed using fuzzy logic and compared to the conventional Reliability technique using the first-order second-moment method. Soil liquefaction potential was properly calculated using both approaches for the 71 boreholes in and around Agartala city. The outcomes are shown as contour maps representing spatial variations of the probability of liquefaction at different depths. In this study, Fuzzy logic is used to model the relationships between different soil parameters, which can help better understand the soil\'s behaviour during liquefaction. This developed method can assess the vulnerability of liquefaction potential and select appropriate materials and construction processes.

ICMS: REPERCUSSÕES ECONÔMICAS DA TRIBUTAÇÃO INTERESTADUAL E ALTERNATIVAS DE MUDANÇA
Authors: Pedrosa Ivo Vasconcelos
Published: December 2023

Examina questões relativas ao Imposto sobre Circulação de Mercadorias e Prestação de Serviços de Transportes e Comunicações (ICMS), principalmente as relacionadas com a distribuição de receita entre os Estados e o Distrito Federal. Mostra que o rateio desse imposto pelos Estados, baseado em alíquotas diferenciadas, usadas quando transações envolvem compradores de um Estado e vendedores de outro, deveria ser mudado porque provoca problemas relativos às decisões sobre localização das unidades de produção e ou distribuição. Pesquisa junto aos 5.000 maiores contribuintes do ICMS de Pernambuco, no ano de 1996, evidencia a correlação entre as alíquotas diferenciais e a carga de imposto, medida pela relação entre o imposto e o valor adicionado pela unidade econômica. Conclui que o tipo de tributação adotado pelos Estados no Brasil favorece a região Sudeste, onde existe metade da indústria nacional, porque as unidades econômicas situadas lá pagam menos imposto que as localizadas nas regiões pobres, menos industrializadas. Propõe um novo mecanismo de distribuição de receita entre as Unidades Federadas, de modo a reduzir o processo de concentração econômica.
Salam, Islam, and the Bomb: Exploring the Ahmadiyya Muslim Community’s Perspective
Authors: Rameez Raja
Published: December 2023

For atomic powers, surrendering nuclear weapons is tough but not impossible if their hatred is turned into amity and concord. Even though Islam encourages peace, few scholars have utilized the Holy Quran to endorse nuclear weapons for deterrence, which may incite Muslim states to obtain nuclear weapons. Abdus Salam, a Pakistani academic and scientist, is accused of assisting Islamabad in bomb-making while belonging to the Ahmadiyya Muslim Community, which opposes the introduction/use of nuclear weapons. Similarly, scientist Robert Oppenheimer openly contributed to the bomb-making in the United States which ultimately resulted in the mass murder of innocent Japanese people. This article tackles various people's concerns regarding Salam's ties with Pakistan's nuclear weapons. It is my attempt to refute the studies/allegations that Islam favours weapons of mass destruction for deterrence, security, and peace, so addressing the case of Salam, who became unjustly associated with nuclear weapons.

Between the lines, it will discuss how Laila Lalami’s short story “The Fanatic” shows how the rise of political Islam in Morocco is partly responsible for conflicts between parents and their children. While the parents embrace what they perceive as a liberal Western culture, the children choose to support Islamic movements for political purposes. Hanif Kureishi, a Pakistani-British author, uses the theme of the generational gap, like Lalami, to critique the contentious environment that political Islam has created. Specifically, in his work “My Son the Fanatic,” he intentionally opens a debate on multiculturalism, cultural identity, and alienation to demonstrate how Western media’s misrepresentation of Islam easily creates a cultural struggle between parents and their children. Therefore, this article will compare the two short stories and eventually discuss how political Islam after the Iranian revolution in 1979 significantly had an impact on Muslim youths, whether at home or in diaspora.

Estrategia para la atención del recién nacido con cardiopatías congénitas en Belice
Authors: Pedroso Filiberto Eduardo
Published: December 2023

Las cardiopatías congénitas tienen una incidencia a nivel mundial, según la OMS, aproximadamente de 6 – 8 por 1 000 nacidos vivos, de las que 3 x 1000 serían consideradas críticas, con un 70 % de probabilidades de fallecer en el primer mes de vida de no realizársele algún tipo de cirugía paliativa en ese tiempo. Uno de los retos a los que se enfrentan los países subdesarrollados es el poder garantizar estos costosos tratamientos, que requieren además de un bien coordinado sistema de salud, lo cual en ocasiones se hace difícil de lograr. Para hacer más efectiva la ayuda solidaria de los países con condiciones para prestar esta atención a los países económicamente en desventaja, estos últimos han de tener un mínimo de atención cardio-pediátrica que facilite el diagnóstico temprano. La orientación, por parte del equipo médico a la futura madre, del nacimiento de este en un centro médico de recepción pre-natal con condiciones para su mejor atención al momento de nacer es esencial. En las condiciones actuales de Belice, el Hospital ¨Karl Heusner Memorial¨, que cuenta con un equipo formado por obstetras, neonatólogos y cardio-pediatra, apoyados con las condiciones de la unidad de cuidados intensivos neonatales (NICU), es la institución de referencia.
Neurofibromatosis tipo 2. Presentación de un caso y revisión del tema
Authors: Herrera Pérez Belkis Milady , Mantilla Villegas Yadira
Published: December 2023

La neurofibromatosis tipo 2 es una enfermedad poco frecuente, caracterizada por presentar tumores cerebrales de tipo benigno, centralmente localizados. Debido a que crecen lentamente, pueden estar inertes durante muchos años antes de empezar a provocar síntomas. La presencia de schwannomas vestibulares bilaterales o unilaterales es muy característica, aunque puede acompañarse también de meningiomas, gliomas y cataratas subcapsulares. Se presenta un paciente de 28 años de edad,masculino, con cuadro clínico de 7 años de evolución, progresivo, determinado por aumento de volumen de la región parietal izquierda y pérdida de la audición bilateral. Se realizaron estudios de neuroimagen. La tomografía computadorizada identificó un meningioma en placa y meningioma de la convexidad. El estudio de resonancia magnética reveló la presencia de schwannomas vestibulares bilaterales, un neuroma del cuero cabelludo y un tumor intramedular. Se diagnostica el paciente como neurofibromatosis tipo 2; se realiza la resección quirúrgica de los meningiomas y se evoluciona con neuroimagen.

Published: December 2023

Se estudió la flora bacteriana y su patrón de sensibilidad antimicrobiana en la cavidad oral de 33 monos Saimiri oerstedii: 31 silvestres y 2 en cautiverio. Con torunda estéril se rasparon los dientes y la cavidad bucal de cada mono y se resuspendió en 2 mL de solución salina estéril (0.85%); se prepararon tubos de transporte para cultivos aerobios y anaerobios y una vez en el laboratorio, se inocularon placas de agar sangre que se incubaron en aerobiosis y anaerobiosis. Los aislamientos se identificaron con sistemas miniaturizados API® (20NE, Staph y 20A); las determinaciones de la sensibilidad a los antibióticos se realizaron con galerías ATB® (G5, Staph y ANA). Se aislaron 137 cepas bacterianas: 106 aerobias (77.4%) y 31 anaerobias (22.6%). El predominio fue de bacilos Gram negativos aerobios (100 cepas), siendo Enterobacter el género más frecuente (42%), seguido de Burkholderia y Aeromonas (27% c/u); los anaerobios más comunes fueron Clostridium (36%) y Fusobacterium (12%). Estos resultados revelan semejanzas y diferencias con respecto a la flora oral humana y la de otros monos costarricenses; la alta frecuencia de algunos géneros sugiere que son parte de la flora oral de monos y no contaminación secundaria de bacterias del suelo. El 90% de los bacilos Gram negativos aerobios fue resistente a cefalotina y el 89% a cefoxitina; altas tasas de resistencia se presentaron también ante otras drogas; solamente ceftriaxone y pefloxacina fueron efectivos contra todas las cepas analizadas; sólo dos cepas fueron sensibles a todos los antibióticos evaluados. El mayor porcentaje de resistencia en anaerobios ocurrió ante el metronidazole (26 a 35%) seguido por cefotetán (26%) y clindamicina (23%); el 39% de los aislamientos fue sensible a todos los antibióticos evaluados. La resistencia múltiple fue menor en los anaerobios (26%) que en los aerobios (77%). Este estudio contribuye al conocimiento y a la preservación del mono tití, especie ame- nazada, y muestra que pocas barreras son capaces de contener los genes de resistencia y sus hospederos bacterianos, aun en animales silvestres.

Using camera traps to determine group demography in a paraguayan population of Sapajus cay
Authors: Smith Rebecca L. , Briggs Emily S.
Published: December 2023

The understudied Hooded Capuchin (Sapajus cay) is the only representative of its genus in Paraguay. The species is distributed throughout the Upper Paraná Atlantic Forest, a biome that historically covered most of eastern Paraguay but has been reduced to small, isolated fragments by agricultural encroachment. Understanding group composition and demographics is important for monitoring the viability of populations. In this study, video camera traps were used to monitor a single group of Hooded Capuchins during their visits to a provisioning platform in a small Atlantic Forest fragment in Reserva Natural Laguna Blanca, Departamento San Pedro, Paraguay. Video analysis enabled identification and assignation of age classes to all 18 individuals of the group. Sex determination was possible for 8 adults, 2 subadults, and 2 juveniles. This study provides the first information of group demographics and composition of wild Hooded Capuchins in Paraguay.
