Published: February 2023

The stock structure of western North Atlantic bottlenose dolphins (Tursiops truncatus) is complex, with seasonally migratory stocks often overlapping with year-round resident stocks. High rates of exchange between northernmost sites have been documented but movement and seasonal fluctuation in abundance among sites along the southern portion of the US Atlantic coast is not well understood. To better understand seasonal abundance, a three-year mark-recapture study of bottlenose dolphins in coastal and estuarine waters near Charleston, South Carolina, USA was conducted. A robust design was employed in order to minimise bias and more precisely determine seasonal estimates of abundance and concurrently examine temporary immigration/emigration and survivorship. Systematic boat-based surveys were carried out (n = 192) from January 2004 to December 2006. The entire study area was surveyed one week per month; an additional survey was conducted in the months in which seasonal abundance was estimated: January (winter), April (spring), July (summer) and October (autumn). Standard photo-identification techniques were used to accumulate sightings of 521 distinctively marked dolphins, 65% of which were sighted more than once. Pollock’s robust design was applied using MARK and the ensuing abundance estimates were adjusted for the seasonal proportion of unmarked dolphins (ranging from 0.27 to 0.40) in the population. Estimates ranged from 364 (95% CI = 305–442) in January 2004 to 910 (95% CI = 819–1018) in October 2006. Summer abundance estimates were consistently greater than those from winter months, although estimates varied considerably among years. The same model was used to calculate an annual survival rate estimate of 0.951 (95% CI = 0.882–1.00) for marked individuals within the population. A high degree of transience, demonstrated by seasonal influxes of single-sighted individuals, made it difficult to differentiate between mortality and permanent emigration. The results support the occurrence of three distinct dolphin groups found in Charleston waters: year-round residents; seasonal residents; and transients. Reporting abundance and survivorship estimates together is useful in explaining and validating results for populations in which transient individuals occur. These results provide important information for stock and viability assessment of coastal bottlenose dolphins in the western North Atlantic.

Diante da crescente demanda acerca da educação de alunos surdos, bem como da necessidade de uma formação de base e continuada para alunos-professores e professores criarem ambientes de aprendizagem no contexto da educação bilíngue para alunos surdos, este relato apresenta e analisa uma proposta formativa e colaborativa, desenvolvida no âmbito do Programa Institucional de Bolsas de Iniciação à Docência (Pibid), de um grupo de trabalho que implementou ações de imersão e práticas educativas com alunos surdos de uma escola-polo bilíngue do município de Guarulhos. Era objetivo do grupo que os pedagogos, em seu processo de formação inicial, compreendessem questões implícitas ao trabalho docente, direcionado a alunos surdos. Em encontros semanais que aconteciam na universidade, a coordenadora de área do Pibid, também professora na universidade, e a supervisora do programa, também professora na escola-polo bilíngue, organizavam momentos formativos com os alunos-professores que envolviam estudos teórico-práticos e planejamento intervenções com os alunos surdos. A proposta formativa revelou que os alunos-professores passaram a problematizar questões concernentes à educação de alunos surdos, ultrapassando o conhecimento das especificidades linguísticas e aproximando-se das particularidades inerentes às práticas pedagógicas bilíngues.
A Collaborative Acting between School and University: The Formative Experience in Institutional Program of Initiation to Teaching Scholarship in Bilingual Classes of Deaf Students
Abstract
With the growing demand for the deaf students education, as well as the need for basic and continuous training for student-teachers and teachers of a university to create learning environments in the context of bilingual education for deaf students, this report presents and analyzes a formative and collaborative proposal, developed within the scope of the Institutional Program of Initiation to Teaching Scholarship, Pibid in Brazil, of a working group that implemented immersion actions and educational practices with deaf students from a bilingual school in the city of Guarulhos. It was the group's objective that pedagogues, in their initial training process, understood implicit issues in teaching deaf students. In weekly meetings that took place at the university, the Pibid area coordinator, also a professor at the university, and the program supervisor, also a teacher at the bilingual school, organized training moments with student-teachers that involved theoretical and practical studies and interventions with deaf students. The formative proposal revealed that student-teachers began to problematize issues concerning the education of deaf students, surpassing the knowledge of linguistic specificities and approaching the particularities inherent to bilingual pedagogical practices.

Contemporary art and networks: Analysis of the Venus Project using the UCINET software
Authors: Benito Patricia V.
Published: February 2023

During the first years of the 21st century, the political, economic, and institutional crisis in Argentina, linked to the fall of the convertibility plan; led to the strengthening of associative, collaborative, and community livelihoods (Hintze, 2003; Palomino, 2005; Pastore, 2010). In dialogue with this situation, from the field of visual arts, the Venus Project arises, a network of artists created in Buenos Aires, Argentina. Venus, operated from 2002 to 2006, offers a virtual and analog platform for exchanging services, goods, skills, and/or knowledge between artists and agents interested in cultural consumption and its management. The project aimed to create a micro-community with an experimental authartic economy and its own currency (Pauls, 2002; Sainz and Solaas, 2007; Krochmalny, 2008; Rubinich, 2009; Jacoby, 2011). Throughout its five years, the network had more than 600 members linked through offers and demands. In the present work, the reconstruction of the total network of experience is proposed to identify the flow of exchanges and analyze their effectiveness. Our hypothesis is that it failed to function as an economic device, framed within a collective artistic proposal. In turn, for the survey of our corpus, we use techniques that come from ethnography, data that will be analyzed later from the UCINET software.

Authors: M. Kannan  , R. Thangavel
Published: February 2023

One of the most significant industries, agriculture, is crucial to the socio-economic progress of a nation like India. In agriculture, maintaining crops and preventing illness are difficult undertakings. They need professional human resources for the job, but it is really tough to find an experienced person. Foliar diseases in turmeric plants often cause significant reduction in both quality and quantity and result in economic loss for turmeric products. This paper presents an efficient image segmentation method using Spatial Fuzzy C means algorithms (FCM) to improve the segmentation accuracy using turmeric plant leaf images. The proposed method utilizes the advantage of noise-robust nature and provides more information in segmentation process. Moreover, spatial FCM algorithm is employed to overcome the limitation of K means and fuzzy C means (FCM) algorithm. The benefit of the spatial FCM algorithm for image segmentation in the sense of low computation time and the advantages of spatial FCM algorithm in the sense of accuracy are considered. The challenging task of proposed spatial FCM algorithm for image segmentation performance are analysed and evaluated based on their parameter like MSE, PSNR and Accuracy.
O Brasil na Modernidade e a Modernidade no Brasil: a atualização do discurso de dominação
Authors: Lanças Vinicius Ramos
Published: February 2023

Este ensaio pretende tratar do Brasil e da modernidade, desta enquanto fenômeno macro político e daquele enquanto parte desse fenômeno. É preciso falar do Brasil para que possamos nos conhecer e reconhecer, nos vários sentidos que essas palavras abarcam. Entender o Brasil enquanto uma espécie de reverberação dessa modernidade auxilia na compreensão do conjunto valorativo que orienta as ações contemporâneas, mas é preciso extrapolar as fronteiras da análise sincrônica e pensar como isso foi construído ao longo do tempo e que características imanentes puderam se manter inalteradas em séculos de continua transformação. Compreender isso permite traçar uma crítica interna, na medida em que ajuda a desencobrir o discurso auto-legitimador do status quo e ajuda a compreender também padrões de dominação modernos que operam não apenas aqui, mas em boa parte do mundo, tornando a experiência brasileira útil, se não exemplar, para futuras análises de sociedades que partilhem essa característica chamada ‘modernidade’.

An Intrusion Detection Mechanism for MANETS based on Deep Learning Artificial Neural Networks (ANNS)
Authors: Sultan Mohamad T , Sayed Hesham El , Khan Manzoor Ahmed
Published: February 2023

Mobile Ad-hoc Network (MANET) is a distributed, decentralized network of wireless portable nodes connecting directly without any fixed communication base station or centralized administration. Nodes in MANET move continuously in random directions and follow an arbitrary manner, which presents numerous challenges to these networks and make them more susceptible to different security threats. Due to this decentralized nature of their overall architecture, combined with the limitation of hardware resources, those infrastructure-less networks are more susceptible to different security attacks such as black hole attack, network partition, node selfishness, and Denial of Service (DoS) attacks. This work aims to present, investigate, and design an intrusion detection predictive technique for Mobile Ad hoc networks using deep learning artificial neural networks (ANNs). A simulation-based evaluation and a deep ANNs modelling for detecting and isolating a Denial of Service (DoS) attack are presented to improve the overall security level of Mobile ad hoc networks.
Spectrum Sharing between Cellular and Wi-Fi Networks based on Deep Reinforcement Learning
Authors: Ragchaa Bayarmaa , Kinoshita Kazuhiko
Published: February 2023

Recently, mobile traffic is growing rapidly and spectrum resources are becoming scarce in wireless networks. Due to this, the wireless network capacity will not meet the traffic demand. To address this problem, using cellular systems in an unlicensed spectrum emerged as an effective solution. In this case, cellular systems need to coexist with Wi-Fi and other systems. For that, we propose an efficient channel assignment method for Wi-Fi AP and cellular NB, based on the DRL method. To train the DDQN model, we implement an emulator as an environment for spectrum sharing in densely deployed NB and APs in wireless heterogeneous networks. Our proposed DDQN algorithm improves the average throughput from 25.5% to 48.7% in different user arrival rates compared to the conventional method. We evaluated the generalization performance of the trained agent, to confirm channel allocation efficiency in terms of average throughput under the different user arrival rates.

Maize (Zea mays) is a cereal of great importance for human and animal food security. Yields are conditioned by genetic and nutritional factors, especially Nitrogen (N), incorrect application can affect grain yield or cause environmental damage. In this research, the effect of two commercial hybrids of hard yellow maize by nitrogen dose and grain yield was studied. This work was carried out during the months of June to November of the year 2019, in the premises of the Pichilingue Tropical Experimental Station at the National Institute of Agricultural Research (INIAP), belonging to Mocache canton, Los Ríos province. Doses of 0, 69, 138, 207 y 276 kg.ha-1of nitrogen were evaluated. For the development of the research, a plot of 1440 m2 was used, designed in complete blocks at random in divided plots, with three repetitions and twelve treatments. The variables were subjected to statistical analysis and the analysis of variance was used to determine the interaction between hybrids and nitrogen, the means of each treatment were compared using Tukey's test (p>0.05). The high-yield hybrid H2 expressed its productive potential with the evaluated doses of N; however, doses higher than 69 kg.ha-1of N are not necessary for this hybrid as it has the same behavior in its grain yield.

Cocoa (Theobroma cacao L.) is a crop of economic importance distributed in 50 countries. It has great connotation in the international market and the chocolate industry. Its productivity in the field is limited by biotic and abiotic conditions; the same onesthat affect the fertilization of the flower. For this reason, the objective of this documentary research work is to know the incidence of more efficient pollinating agents on the fertilization of the cocoa flower. The bibliographic review was based on collecting information from primary sources that expose results of studies on entomophilous pollination of cocoa crop flowers, giving greater importance to research carried out in Ecuador. Emphasis was placed on the biotic factors of the agro-system of cocoa cultivation, such as the tree species that favor the habitat of the different pollinating agents; among the abiotic factorsarewind, water, temperature, humidity and soil. In the consulted literature, it was found that the most relevant benefits of the presence of pollinators in the cocoa crop are the increase in fertilized flowers and therefore the production of cobs.It is concluded that the interaction of the different populations of pollinating agents with biotic and abiotic factors within the crop ecosystem favors cocoa production. Therefore,it is advisable to use good techniques in the management of the plantation to guarantee the presence of pollinators.

Chaos in a Pendulum Adaptive Frequency Oscillator Circuit Experiment
Authors: Lİ Xiaofu , BEAL Aubrey , DEAN Robert , PERKİNS Edmon
Published: February 2023

Adaptive oscillators can learn and encode information in dynamic, plastic states. The pendulum has recently been proposed as the base oscillator of an adaptive system. In a mechanical setup, the horizontally forced pendulum adaptive frequency oscillator seeks a resonance condition by modifying the length of the pendulum's rod. This system stores the external forcing frequency when the external amplitude is small, while it can store the resonance frequency, which is affected by the nonlinearity of the pendulum, when the external amplitude is large. Furthermore, for some frequency ranges, the pendulum adaptive frequency oscillator can exhibit chaotic motion when the amplitudes are large. This adaptive oscillator could be used as a smart vibratory energy harvester device, but this chaotic region could degrade its performance by using supplementary energy to modify the rod length. The pendulum adaptive frequency oscillator’s equations of motions are discussed, and a field-programmable analog array is used as an experimental realization of this system as an electronic circuit. Bifurcation diagrams are shown for both the numerical simulations and experiments, while period-3 motion is shown for the numerical simulations. As little work has been done on the stability of adaptive oscillators, the authors believe that this work is the first demonstration of chaos in an adaptive oscillator.

Geçtiğimiz yüzyılın başlarından itibaren hızlanan kırsal yerleşim alanlarından kentlere göçün ortaya çıkardığı aşırı nüfus yoğunluğu ve mega kentler, bu kentlerde yaşayanların barınma sorunu da beraberinde getirmiştir. Yerel yönetimlerin bu sorunun çözümünde çok farklı yöntemler geliştirse de kent yayılmasının önüne geçilememiştir. Şüphesiz ki bu durum kenti besleyen kıymetli tarım topraklarının da imar planlarına dâhil edilmesi anlamına gelmektedir. Bu nedenle kentlerin çeperlerinde tarım yapmaya elverişli kırsal alanlar her geçen gün azalmakta ve kentlerin kendini besleyebilme kabiliyeti zayıflamaktadır. Geldiğimiz noktada kentliler sağlıklı ve ucuz gıdaya erişim anlamına gelen “Gıda Güvenliği” sorunu ile karşı karşıya kalmaktadır. Merkezi ve yerel hükümetlerin sürdürülebilir kalkınma amaçları kapsamında; kent toprağı ve dolayısıyla tarımının korunması her geçen gün daha da önem kazanmaktadır. Bunun için kentsel kullanım alanlarının doğal kaynakları koruyacak şekilde planlanması ve nihayetinde tarımın da kent planlarına dâhil edilmesi elzemdir. Tarımsal alanlarının kent planlarına dâhil edilmesi, kavramsal olarak her ne kadar kentin kırsala yaklaşımını çağrıştırsa da esasen tarımın kente uyumlanması anlamına gelmektedir. Zira kent tarımı kısıtlı alanlardan maksimum verimi almayı hedefleyen teknik ve yöntemlerle yapılmaktadır. Şüphesiz kentsel alanlarda tarla ölçeğinde tarım yapılması olası değildir. Bu nedenle yakın gelecekte “Tarım Arsaları” kavramı kaçınılmaz bir şekilde yakın gelecekte en sık duyduğumuz kavram haline gelecektir.

Abstract. The Arctic is a rapidly changing ecosystem, with complex ice–ocean–atmosphere feedbacks. An important process is new particle formation (NPF), from gas-phase precursors, which provides a climate forcing effect. NPF has been studied comprehensively at different sites in the Arctic, ranging from those in the High Arctic and those at Svalbard to those in the continental Arctic, but no harmonised analysis has been performed on all sites simultaneously, with no calculations of key NPF parameters available for some sites. Here, we analyse the formation and growth of new particles from six long-term ground-based stations in the Arctic (Alert, Villum, Tiksi, Zeppelin Mountain, Gruvebadet, and Utqiaġvik). Our analysis of particle formation and growth rates in addition to back-trajectory analysis shows a summertime maxima in the frequency of NPF and particle formation rate at all sites, although the mean frequency and particle formation rates themselves vary greatly between sites, with the highest at Svalbard and lowest in the High Arctic. The summertime growth rate, condensational sinks, and vapour source rates show a slight bias towards the southernmost sites, with vapour source rates varying by around an order of magnitude
between the northernmost and southernmost sites. Air masses back-trajectories during NPF at these northernmost sites are associated with large areas of sea ice and snow, whereas events at Svalbard are associated with more sea ice and ocean regions. Events at the southernmost sites are associated with large areas of land and sea ice. These results emphasise how understanding the geographical variation in surface type across the Arctic is key to understanding secondary aerosol sources and providing a harmonised analysis of NPF across the Arctic.
Assessment of frost damage risk in a historic masonry wall due to climate change
Authors: Choidis Petros , Coelho Guilherme Barreto Arez , Kraniotis Dimitrios
Published: February 2023

Abstract. Historic masonry buildings are an integral part of human cultural heritage, and they need to be preserved for future generations. Brick is susceptible to frost damage which is common in regions with cold and humid climates. The frost damage on the masonry walls is accumulated over the years becoming more and more critical for the integrity of the historic buildings and it is also affected by climate change (CC). In the current research, the focus was placed on a coastal region in southern Norway with a significant number of historic masonry buildings. The frost damage risk of the masonry walls was assessed by using data from a climate reanalysis for the present conditions and from a climate model under past, present, and future conditions. Two climate-based (CB) indices accounting for the air temperature and one material response-based (MRB) index considering the temperature and moisture content inside a simulated masonry wall were used for the frost damage risk assessment. The inputs for the MRB index were calculated by heat, air, and moisture (HAM) transfer simulations. Within the HAM simulations, the indoor climate was in one case representative of an unconditioned building with air leakages and many openings, while in the second case it was representative of a small, conditioned room. The overall impact of CC was a decrease in the frost damage risk of the masonry walls. However, an increased frost damage risk was observed from the present to the future conditions according to the MRB index for the walls of small, conditioned rooms with higher driving rain load and lower solar radiation gains. The (i) number of freeze-thaw events, (ii) periods during which freeze-thaw events occur, and (iii) CC-related trends varied based on the considered index with the most explicit risk assessment being the MRB one. Moreover, the freeze-thaw events experienced by the masonry walls of unconditioned, leaky buildings were 20 times more than the ones for the small, conditioned rooms. Significant differences were observed between the results from the climate model and the climate reanalysis which were mainly linked to the underestimation of the air temperature and the overestimation of the precipitation by the climate model. The outputs of the MRB index were translated into certain damage categories while suggestions on improving the limitations of the current research were made.
Exploiting the signal to noise ratio in multi-system predictions of summertime precipitation and maximum temperatures in Europe
Authors: Acosta Navarro Juan Camilo , Toreti Andrea
Published: February 2023

Abstract. Droughts and heatwaves are among the most impactful climate extremes. Their co-occurrence can have devastating consequences on natural and human systems. Early information on seasonal timescales on their possible occurrence is beneficial for many stakeholders. Seasonal climate forecast has gradually become more used; but limited skill in certain regions and seasons still hinders a broader use. Here we show that a simple forecast metric from a multi-system ensemble, the signal to noise ratio, can help overcome some limitations in the boreal summer. Forecasts of maximum daily near surface air temperature and precipitation in boreal summers with high signal to noise ratio tend to coincide with observed larger deviations from the mean than years with small signal to noise ratio. The same metric also helps identify processes relevant to seasonal climate predictability. Here we show that a positive phase of a North Atlantic Sea surface dipole during boreal spring may favor the occurrence of dry and hot summers in Europe.

Abstract. Microbial release of CO2 from soils to the atmosphere reflects how environmental conditions affect the stability of soil organic matter (SOM), especially in massive organic-rich ecosystems like the peatlands and grasslands of the Qinghai-Tibetan Plateau (QTP). Radiocarbon (14C) is an important tracer of the global carbon cycle and can be used to understand SOM dynamics through the estimation of time lags between C fixation and respiration, often assessed with metrics such as age and transit time. In this study, we incubated peatland and grassland soils at four temperature (5, 10, 15 and 20 °C) and two water-filled pore space (WFPS) levels (60 and 95 %), and measured the 14C signature of bulk soil and respired CO2. We compare the relation between the Δ14C of the bulk soil and the Δ14CO2 of respired carbon as a function of temperature and WFPS for the two soils. To better interpret our results, we used a mathematical model to analyse how the calculated number of pools, decomposition rates of carbon (k), transfer (α) and partitioning (γ) coefficients affect the Δ14C -bulk and Δ14CO2 relation, with their respective mean age and mean transit time. From our incubations, we found that 14C from peatland was significantly more depleted (old) than from grassland soil. Our results showed that changes in temperature did not affect the Δ14C values of respired CO2 in either soil. However, changes in WFPS had a small effect on the 14C CO2 in grassland soils and a strong influence in peatland soils, where higher WFPS levels led to more depleted Δ14CO2. In our models, we observed large differences between slow and fast cycling systems, where low values of k modified Δ14C patterns due to the incorporation of 14C-bomb in the soil. Hence, the correspondence between Δ14C and age and transit time strongly depended on the internal dynamics of the soil (k, α, γ and number of pools) as well as on model structure. We conclude that the stability of carbon in these systems depends strongly on the direction of change in temperature and moisture and how it affects the rates of SOM decomposition. Finally, Δ14C modelling along with empirical data from SOM dynamics is a useful tool to improve predictions on interactions between terrestrial and atmospheric carbon.
Evidence-based requirements for perceptualising intercatchment groundwater flow in hydrological models

Abstract. Groundwater-dominated catchments are often critical for
nationally important water resources. Many conceptual rainfall–runoff models
tend to degrade in their model performance in groundwater-dominated
catchments, as they are rarely designed to simulate spatial groundwater
behaviours or interactions with surface waters. Intercatchment groundwater
flow is one such neglected variable. Efforts have been made to incorporate
this process into existing models, but there is a need for improving our
perceptual models of groundwater–surface water interactions prior to any
model modifications. In this study, national meteorological, hydrological, hydrogeological,
geological and artificial influence (characterising abstractions and return
flows) datasets are used to infer a perceptual model of intercatchment
groundwater flow (IGF) and how it varies across the river Thames, United
Kingdom (UK). We characterise the water balance, presence of gaining/losing
river reaches and intra-annual dynamics in 80 subcatchments of the river
Thames, taking advantage of its wealth of data, densely gauged river
network and geological variability. We show the prevalence of non-conservative river reaches across the study
area, with heterogeneity both between, and within, geological units, giving
rise to a complex distribution of recharge and discharge points along the
river network. We infer where non-conservative reaches can be attributed to
IGF and where other processes (e.g. surface water abstractions) are the
likely cause. Through analysis of recorded reach length water balance data
and hydrogeological perceptualisation, we conclude that outcrops of
carbonate fractured aquifers (Chalk and Jurassic limestone) show evidence of
IGF both from headwater to downstream reaches, and out-of-catchment via
spring lines. We found variability across the study area, with more
seasonality and variability in river catchments on Jurassic limestone
outcrops compared to Chalk and Lower Greensand outcrops. Our results
demonstrate the need for local investigation and hydrogeological
perceptualisation within regional analysis, which we show to be achievable
given relatively simple geological interpretation and data requirements. We
support the inclusion of IGF fluxes within existing models to enable
calibration improvements in groundwater-dominated catchments, but with
geologically specific characteristics, and (when perceptually appropriate)
connectivity between catchments.

Nilai Dan Otoritas Firman Tuhan Menurut Kitab Mazmur 19 Bagi Kehidupan Para Hamba Tuhan
Authors: Maria Hanie E.
Published: February 2023

Taurat, yakni Firman Allah, merupakan landasan hidup umat Tuhan. Dualoh batu berisi ringkasan dari semua perintah dan ketetapan Tuhan yang diberikan kepada Musa, bagi umat Tuhan. Dua loh batu itu kemudian disimpan dalam tabut perjanjian, yang selalu diletakkan di ruang Maha Kudus, kemah pertemuan atau di Bait Allah. Disebut “kemah pertemuan” atau Bait Allah karena merupakan tempat di mana Allah ingin bersekutu dengan umat-Nya.

                Dalam sejarah bangsa Israel, ternyata mereka sering mendukakan hati Tuhan, dengan mengabaikan atau menyimpang dari Firman Tuhan, yang berdampak dalam kehidupan yang tidak berkenan kepada Tuhan, baik secara spiritual, moral, dan praktis.

                Adapun tujuan penelitian ini adalah untuk menjelaskan bahwa Firman Allah memiliki nilai dan otoritas tinggi dalam hidup orang percaya. Dan metode penelitian yang penulis pakai adalah eksegetis terhadap teks Mazmur 19, dan untuk mendapat data konkrit tetang kehidupan orang percaya dalam kaitannya dengan Firman Tuhan, maka penulis menyebarkan angket, dengan sembilan pertanyaan terbuka dan satu pertanyaan tertutup
The Impact of COVID-19 on Access, Delivery, and Utilisation of Essential Primary Healthcare in Region 4 of Guyana
Authors: Jhagru Hemchand
Published: February 2023

Background: The COVID-19 pandemic has posed considerable operational challenges for public health systems to deliver COVID-19 response and maintain essential health services simultaneously. Low-resource countries were significantly affected by the COVID-19 pandemic because of weak health infrastructure, reduced health systems capacity and significant socio-economic inequalities.
Objectives: This study aimed to explore the impact of COVID-19 on access, delivery and utilisation of essential primary health services in Region 4 of Guyana.
Methods: An explanatory sequential study design was used to collect data on health services utilisation from 41 health centres in Region 4. The statistical data informed a semi-structured questionnaire to explore community and healthcare providers' perceptions of the COVID-19 pandemic and their experiences concerning access and delivery of primary health services during the COVID-19 pandemic in Guyana. The statistical data were analysed descriptively with SPSS version 20 software and by time series trend analysis. The qualitative data were descriptively analysed with SPSS software and by thematic analysis.
Results and Discussion: An analysis of the statistical data showed a stable trend of essential health services utilisation from January 2018 – May 2019. However, during the COVID-19 pandemic, there were significant decreases in utilising all essential health services across the 41 health centres of Region 4. Healthcare providers and community perspectives and experiences identified fear and anxiety among the common causes for decreased access to primary healthcare during the pandemic.
Conclusions: This study confirmed that during the COVID-19 pandemic, access, delivery, and utilisation of essential health services were severely affected in the health centres of Region 4 in Guyana.

TDDFT-DFT Theoretical Method and Topological Analysis to the Behavior Understanding of Two Tungsten Carbonyl Complexes
Authors: M A E Dems M A E Dems
Published: February 2023

We present here a study based on Density Functional Theory (DFT) calculations, to contribute to the understanding of the complexes behavior based on tungsten carbonyls ([W(C7H7NS)(CO)5], [W ( C3H6N2S)(CO)5 ] ), which consider as targets molecules of biological interest and easily detectable probes by IR spectroscopy. The results showed good agreements between the calculated and experimental values of the geometric parameters for the two complexes. A peak in the IR spectrum at 2030 cm-1 is due to the stretching of the C-O triple bond, according to the AIM analysis (0.07 andlt;ρ andlt;0.15 ), the existence of an intermediate interaction between the tungsten and the CO ligand. Moreover, these complexes are stable, the spectra of TD–DFT analysis showed these complexes absorb in the same domain of wavelengths, through absorption features at about 110-160 nm, characterized by natural transitions of HOMO/LUMO; of type MLCT for both complexes
