First Report of Lutzomyia edwardsi and Lutzomyia gasparviannai Infected by Nematodes in a Rio de Janeiro Cave
Authors: Carreira Alves Joao Ricardo
Published: August 2022

In 1984, a case of a wild rodent (Proechimys iheringi) infected with Leishmania (Leishmania) forattinii was reported. Lutzomyia gasparviannai is considered the vector of this etiological agent. In 2001, infection of the species Lutzomyia edwardsi by Leishmania (Viannia) braziliensis was described, suggesting the involvement of L. edwardsi in the transmission cycle of cutaneous leishmaniasis. In 2002, in the Lapinha cave, Belo Horizonte, Minas Gerais, Brazil, specimens of Lutzomyia longipalpis infected by nematodes were captured, providing motivation for studies on the biological control of phlebotominae. Thus, the aim of this study was to collect data from phlebotominae species in Sumidouro, Rio de Janeiro, Brazil. Specimens were captured in a cave and the surrounding Atlantic Forest using Center of Disease Control traps, twice a month, overnight from 18h to 6h. The collection periods were from June 2009 to May 2010 and from March 2015 to February 2016. The phlebotominae were mounted on slides and covered with coverslips at the Oswaldo Cruz Institute. A female L. edwardsi specimen infected with nematodes, captured in 2009, and a female Lutzomyia gasparviannai specimen infected with Wuchereria bancrofti, captured in 2015, were among the collected specimens. Phlebotominae and nematodes were identified by morphological analysis, using an optical microscope. The nematode species W. bancrofti was identified by the curator of the Helminth Collection of the Oswaldo Cruz Institute, where it was deposited along with the L. gasparviannai specimen. Exemplars of L. gasparviannai were deposited in the Entomological Collection of the Oswaldo Cruz Institute. The slide containing L. edwardsi and the nematodes was deposited in the Entomological Biodiversity Laboratory. This is the first report of W. bancrofti nematodes in these species, in a cave, and in the state of Rio de Janeiro. Thirteen species of phlebotominae were collected. L. gasparviannai was the most frequent, followed by L. edwardsi. The predominance of these two species, considered vectors of the etiological agents of leishmaniasis, and their nematode infections suggest that studies on the biological control of nematodes should be conducted and that cases of filariasis in this region should be assessed.
Anesthesia and Braquial Plexus Block in Nine-Banded Armadillo (Dasypus novemcinctus)-Case Report
Authors: Souza Lucchi Sophia
Published: August 2022

The nine-banded armadillo (Dasypus novemcinctus) is the most common species of armadillos in North, Central and South Americas. This case report is about an anesthetic procedure of a male armadillo received for rehabilitation with a radioulnar fracture. For the anesthesia, we use methadone, midazolam, s-ketamine and isoflurane. We also use a human laryngeal mask for secure airway and brachial plexus block with a peripheral nerve stimulator. There is a little information about anesthesia of these species in the literature and the aim of this work is to contribute to this knowledge. Though it is unknown the minimum alveolar concentration of isoflurane in nine-banded armadillo, we concluded that, with the blockage of the brachial plexus, we saw cardiovascular stability and a decrease in isoflurane use. The reversal of midazolam added to a quick recovery. The human laryngeal mask is effective for inhalation anesthesia in nine-banded armadillo.
Edge Effects and Nature Reserves: A Study of Protected Birds in Grasslands Adjacent to Agricultural Landscapes in a Central Brazilian Cerrado
Authors: P Tubelis, Dárius
Published: August 2022

Although studies of edge effects have great importance for reserve design, they have rarely investigated impacts into nature reserves. This study aimed to examine edge effects associated with adjacent agricultural landscape on birds at Parque Nacional das Emas, Brazil. Study sites [n = 36] were plots in the natural grassland habitat located at four distance bands in relation to the boundary line between protected vegetation and agricultural fields [0-500 m, 500-1,000 m, 1,000-1,500 m and interior]. Birds were surveyed through transect counts between October 2006 and February 2007. GLMMs were used to analyse variation in the abundance of selected species and trophic guilds among distance intervals, while species richness was compared through curves of rarefaction. Variation in community composition was evaluated through Correspondence Analysis. A total of 59 species were recorded. Species more sensitive to proximity to agriculture were insectivores such as Culicivora caudacuta and Alectrurus tricolor. Granivores and omnivores were more abundant close to rather than distant from agriculture. The species richness of the whole community and that of guilds did not vary among distance intervals, as result of species replacement. Communities found in the 0-500 m and 500-1,000 m intervals were very distinct from those of the interior. Edge effects penetrated up to 1,500 m into the park, being more intense within 1 km from adjacent modified landscapes. This study suggests that more effort should be done to establish effective buffer zones [> 1.5 km in width] and avoid the settlement of agribusiness adjacent to nature reserves in Cerrado.
Citizen Science for the Knowledge of Brazilian Birds: Breeding Aspects of the Horned Sungem (Heliactin bilophus) (Aves, Trochilidae) in the Brazilian Cerrado
Authors: Tubelis Dárius P
Published: August 2022

Photographic records produced by citizen scientists have been used by professional ornithologists to study tropical birds. Near 90 species of hummingbirds occur in Brazil, and few of them have had aspects of their breeding investigated in detail. The Horned Sungem Heliactin bilophus is a small hummingbird commonly found in central Brazil, and remains poorly known. This study aimed to investigate breeding aspects of H. bilophus in the Brazilian Cerrado through the use of citizen science data. Searches for photographic records were conducted in three online databases in April 2022. Records with evidences of breeding activities (n = 35) were obtained by citizens along 15 years, and included in this study. Most of them (89%) were obtained in the WikiAves database. They were obtained mainly in central and southeastern Cerrado. Nests were cup-shaped, and fixed to forking branches of shrubs. Most records involved nests, while a minor portion referred to young photographed outside nests. Only female adults were associated with nests or young. Clutch size was always two eggs (n = 6). One or two young were found per nest (n = 10). Most records (66%) occurred in the dry season, and fewer of them (34%) were obtained in the rainy season. They were concentrated during the whole dry season, and the late rainy season, having occurred scarcely in other periods of the year. Each phase of the breeding season (nest building, nests with eggs, downy young, greenish young in nests, and fledged young) lasted for 5-7 months. The breeding season of the Horned Sungem in the Brazilian Cerrado comprises at least 10 months, a period much longer than that considered in previous literature. This study suggests that photographic records available in citizen science databases can improve the knowledge of breeding aspects of hummingbird species found in Brazil.

It can be concluded that Iz covered crops with a planted area of 1.0 m x 1.5 m and Bh with a planting area of 0.5 m x 0.25 m have the most appropriate yield and competitive indices.
Epidermolysis Bullosa. A Rare Disturbance in Clinical Veterinary of Felines
Authors: Errante Paolo Ruggero
Published: August 2022

Epidermolysis bullosa is an inherited group of rare genetic dermatosis characterized by mucocutaneous fragility and blister formation, inducible by often minimal trauma. Epidermolysis bullosa is described in humans and domestic animals, and this dermatosis in humans is classified in four categories based predominantly on the plane of skin cleavage in simplex epidermolysis bullosa, junctional epidermolysis bullosa, dystrophic epidermolysis bullosa and Kindler epidermolysis bullosa. In veterinary medicine the classification of epidermolysis bullosa is based in the human classification the according with the level of ultrastructural separation of skin. The epidermolysis bullosa in cats is a rare disease with a description of isolated cases involving the forms simplex, junctional and dystrophic. The laboratory diagnosis of cats under suspicion of epidermolysis bullosa should include dermo histopathology, transmission electron microscopy, immunofluorescence for antigen mapping and when possible, mutation analysis. There is no specific treatment for epidermolysis bullosa in cats, and care is palliative. The few case reports of epidermolysis bullosa in cats indicates a short time of survival with few months to years, being the cats sacrificed or dying during the first months of life. Due to these factors, it is essential the deep studies of disease in cats so that they can present an increase in expectancy and quality of life.

The Importance of Vitamins E, A and β-Carotene for the Health and Prosperity of Dairy Calves
Authors: Kadek Romana
Published: August 2022

Raising healthy and viable calves is the goal of every farmer who wants healthy cows in their breeding, with excellent milk production and reproductive parameters. And it is not just infectious and metabolic diseases that are clinically visible. Even minor nutritional deficiencies and insufficient supplementation of certain important vitamins and mineral elements can affect the calf's future health and prosperity. This mini-review summarizes the latest results on the importance of vitamins E, A and β- carotene, especially for the antioxidant and immune system of calves. It also discusses briefly effects of vitamins on the hematological profile of calves. A necessary precondition for ensuring the optimal concentration of these vitamins in calves is their sufficient supply in colostrum/milk or milk replacer. Interesting results were obtained by works focused on the effect of vitamin supplementation (parenterally or per-orally) in pregnant cows before parturition on vitamin concentrations in colostrum and plasma/serum of their calves. This can also be a way to ensure a sufficient concentration of vitamins for calves.

Isoglaridacris hexacotyle (Linton, 1897) Mackiewicz, 1968 was found in Catostomus insignis Baird & Girard and Catostomus clarkii Baird & Girard from 3 streams in Arizona. The morphology of I. hexacotyle is revisited using light microscopy revealing new features. Emphasis is placed on the morphological variability of its scolex. The re-examination of 100 more specimens from the Gila River provided an opportunity to revise the taxonomy of the species and correct and update some old statements and concepts by other observers.
Hemolymphangioma of the Neck
Authors: Demidov Valentyn , Cherniak Olha
Published: August 2022

A 26-year-old female patient presented with a painless soft tissue mass at the lower third of the right neck. The mass appearance and growth was noted during last several years. Longitudinal gray-scale ultrasound (US) showed that long-to-short diameter of this cystic lesion measured 3.51 × 2.12 cm (distances are indicated by even calipers ‘+’ and ‘×’) (Panel A: arrow, position of the probe’s side which corresponds to the probe bump and symbolizes the probe side [arrow] at Panel C; arrowhead, septa; C, cystic component; S, solid component). Lesion is visualized as a multicystic mass (hypoechoic with multiple anechoic areas) with septations and a prominent mixed structure (combination of macro- and microcystic cavities). A honeycomb US pattern and no vascular fill of the anechoic areas (Panel B: arrow, position of the probe’s side; asterisk, neck vessel; arrowhead, weak intratumoral blood flow), most likely represented a lymphangioma. Typically, the strong flow signal is noted from 9.30 to 59.37 percent of hemangioma cases. The artifact of acoustic enhancement―common for the fluid-containing structure―was noted posteriorly to the lesion. The fact that the tumor cannot be compressed using probe indicates that the cystic structure differs from the cystic structure of reported US features of cavernous lymphangiomas (sponge-like neoplasms). The capsulated lesion (Panel D: He, hemolymphangioma) was surgically removed under general anesthesia applying the incision along the anterior margin of the right sternocleidomastoid muscle. During tumor removal, light-gray fluid content was partially evacuated due to the rupture of cystic wall. Panel E shows a specimen―the decreased in volume mass―after the evacuation of its cystic content. The spaces of the intratumoral macrocysts are indicated by arrowheads. Histopathological examination established the diagnosis of a ‘hemolymphangioma’ (also known as ‘hemangiolymphangioma’). The patient showed no signs of recurrence at the end of the 36-month follow-up period. Li et al (2017) emphasized that it’s crucial to perform such preoperative imaging, which can help to avoid biopsy upon differential diagnostics between lymphangiomas and vascular malformations with numerous vessels (which can lead to intensive bleeding).8 In summary, hemolymphangioma is a very rare mixed malformation of both blood and lymphatic vessels. Ohsawa et al (2018) concluded that complete excision of hemolymphangiomas provides the best results with a lower recurrence rate. Diagnostic ultrasound and its Doppler option proved efficacy in case of such malformations.

Information is provided on the legislative documents of the Russian Federation regulating activities of the organizations in the field of fire safety. The relevance and expediency are argued related to applying the process approach at the stage of formation and implementation of a fire safety system based on the regulatory legal acts (their individual provisions) containing mandatory requirements, the assessment of compliance with which is carried out within the framework of the federal state fire supervision. The methodological substantiation is presented concerning the process approach to the development of a fire safety system in the organization based on the systematic approach using the well-known PDCA principle, basic issues of its applicability are considered. A conceptual matrix of processes and sub-processes is compiled in accordance with the typology of processes according to ISO (ISO/TC 176/SC 2/N 544R3), management processes of the organization, the processes of measurement, analysis and improvement, the main processes and the processes of resource management are presented, the processes are ranked by levels. A conceptual model is developed for creating a fire safety system based on the process approach, SADT structural analysis and design technology, and IDEF0 functional modeling methodology. The main context diagram of the process of forming a fire safety system in IDEF0 notation, as well as the decomposition of the processes of the second and third levels is considered, all their functional relationships are described. The presented process modeling methodology makes it possible to achieve a positive effect in terms of management, minimization of costs and terms for the development of a fire safety system. It is demonstrated that the process approach used in the design of this system makes it possible to structure the composition of processes, clearly define their input and output parameters, process participants, resources, ensure control and adjustment of the processes.

The article deals with the problem of ensuring the sustainability of functioning of hazardous production facilities in the Donetsk People's Republic. Brief historical remark about the emergence of the problem of increasing the sustainability of the objects functioning is given. The problems of ensuring the sustainability of the functioning of hazardous production facilities faced by the Donetsk People's Republic in the war time are noted. The main ones are named: rational distribution of productive forces; preparation of economic facilities for recovery after the impact of natural and man-made disasters, means of destruction of the enemy; organization of public administration in emergency conditions. It is noted that it is possible to increase the sustainability of the functioning of hazardous facilities through the measures based on the provisions of the regulatory and scientific bases. Quantitative analysis is given in the article concerning potentially hazardous facilities in the Donetsk People's Republic, as well as a description of the hazard classes of production facilities. Considerable attention is paid to the sustainability of the functioning of hazardous production facilities and the reasons that impede its provision in the modern conditions. At present, ensuring the sustainability of the functioning of hazardous production facilities is complicated by the conduct of hostilities. It is proposed to introduce automated industrial safety management systems to increase the sustainability of the operation of hazardous production facilities and reduce the possible risks of emergency situations. Potentially the most hazardous enterprises are indicated in terms of the threat of large-scale emergencies; the necessity of carrying out measures aimed at preventing the threat of emergency situations is emphasized.
Research Into Potential Therapies Against COVID-19, With Focus On Ivermectin
Authors: Khanghah Reza
Published: August 2022

Purpose: Ivermectin is a broad-spectrum antiparasitic and an effective drug to treat COVID-19. In this article, we looked at the effects of ivermectin on coronavirus and its patients in three ways. We have discussed and organized other previously discovered potential therapies and reviewed them in Table 2 and in the last section.

Methods: We searched for articles on MedRxiv, PubMed, Google Scholar, MEDLINE, EMBASE uses the appropriate search terms. ClinicalTrials.gov was searched for available clinical trials evaluating the effectiveness of ivermectin. We also use EU clinical trial registry data and ANZ registry data for clinical trials. Also, we performed our methods in 4 stages: Identifying studies, Selection of Studies, Collating Studies, Reporting results.

Results: Results are variable. Some studies have shown the effectiveness of ivermectin, others have not. Furthermore, some studies show that a combination of ivermectin with other drugs is useful.

Conclusion: Overall, we believe the reason ivermectin is useful is that it goes back to its origin, which is soil. Our theory and hypothesis is that if the coronavirus, created by man or by nature, can generally be treated with nature, that is, the soil. The interesting thing is that today we know that ivermectin is effective in the fight against the coronavirus. In fact, other drugs like teicoplanin, cyclosporine and rapamycin that are effective against the coronavirus have come from the soil. We hope that this article has been able to take a step in finding a corona drug, InshaAllah.
Emotional Acuity in Lorrie Moore’s “How to be an Other Woman” from Self-Help
Authors: Deepa S.
Published: August 2022

Lorrie Moore is one of the famous fictionists of contemporary America. Using the first-and-second-person narratives and shuttling of narrative between past and present, she proves herself a typical postmodernist even in her first collection of short stories titled Self-Help published in 1985. She does not brand herself a feminist, yet woman related issues are dealt by her in almost all the stories in this collection. While focusing her attention on women issues, she relates them to the world which is overflowed with various internal and external relationships. Man-woman relationship in love, marriage and in extra-marital relationship determines woman’s position in the family as well as the society. Hence with the strained relationships the women of Moore suffer from a kind of psychological imbalance and mental turmoil. The protagonist, Charlene of the short story titled “How to be an Other Woman” is obsessed with the thought, being a mistress to a married man and hence suffers from guilty consciousness.

The present research paper aims to find out the effect of the Covid-19 problem on learning English language of students in the Jalgaon District. English is the most important language in the world. In India, use of English language from daily transaction to the Indian constitution is notable. Due to Covid-19, the whole world suffered.  Because of this  pandemic people from the entire world were badly impacted, they suffered a lot economically, socially, and also educationally. COVID-19 is a viral disease so, it can be spread from one person to another through touch. To prevent this COVID-19 there was a lockdown in the whole world. The impact of this lockdown education was provided by the government on the online mode. Students could learn all subjects online but they have difficulty to learning English language because to learn any new language or English there should be social contact and a proper atmosphere to learn that language. Still, In the time of the pandemic, there was no proper atmosphere to spoken English at home, some students faced a problem in learning the English language because they could not afforded a mobile which is important for learning English, and some students were from the rural areas faced network issues, lack of discipline, time table of the study were disturbed, Social distance, and lack of interaction with teachers and friends in English language. Now lockdown is over so all schools and colleges are opening so teachers have to give more attention to their students, they should teach them English from a basic level. Students also need to be focused on improving their English to speak fluent English.
Preliminary Study on the Adhesiveness Properties of Hide Glue
Authors: MIU Lucreția , NICULESCU Mihaela
Published: August 2022

Adhesives based on collagen extracted from the skin, tendons, cartilage, bones of animals and fish have been widely used over time as binders and consolidating agents for various organic and inorganic materials. The use of these types of adhesives or glues or gelatins in the restoration activity has been practiced by restorers due to their properties, but also to the special requirements of reversibility of treatments that are stipulated in national and international norms specific to the restoration of heritage objects. For this purpose, the technology of gelatin extraction from bovine hide was studied, and then gelatins were characterized in terms of chemical properties (ash, total nitrogen, amino nitrogen, dermal substance, pH of analytical solution) and gluing experiments were conducted on collagen substrates (leather and parchment, newly made specifically for the restoration activity and some samples of historical parchment, pieces of parchment detached from the back of a heritage object) and characterized in terms of physical-mechanical properties (shear strength and peel strength). Gelatins made from bovine hide were also compared to a commercial product, rabbit glue, a material frequently used in the field of restoration.

Published: August 2022

Identity authentication and identification as the main activities in the modern human daily life, in the development of social economy and technological innovation of science and technology, information security and public security and other fields of identity recognition technology put forward higher request, not only to accurately record the relevant data information, and use of advanced technology concept advanced authentication technology is put forward. Knowing the living habits of current social residents, they need to choose appropriate ways to prove their identity, whether they enter the computer system or participate in financial services. For example, passwords, keys, ID cards and other contents are traditional means of identity authentication. As the reliability of traditional identity authentication means is getting lower and lower in today’s social network environment, in order to meet the needs of increasingly innovative network platforms and enhance the security and reliability of identity authentication technology, researchers propose to use biometric identification, among which face recognition is the most common. This recognition method is more direct and effective than palmprint, retina, fingerprint and so on, and occupies an important position in the current biometric research topic. After understanding the application of hidden Markov model (HMM) based on wavelet transform and its improved model in the field of face authentication, this paper analyzes the influence of various observation vector optimization methods on the authentication probability, and proposes a dynamic threshold method combined with the authentication model, in order to obtain a better authentication probability. The final design and implementation of the face information as the core of the identity authentication system. The improved hidden Markov model can effectively represent the correlation between face organs, so it has a positive role in the application of face modeling and authentication technology.
Roughness Effects of Textured Surfaces in Hydrodynamic Lubrication
Authors: Bahi Youssef , Gadari Mhammed El , Rahmoune Miloud
Published: August 2022

Several studies have been conducted to improve and model the lubricated contact between surfaces. The main subjects were defining the hydrodynamic parameters to reduce energy losses and protect the environment. Some of the proposed models have studied the effect of textures in hydrodynamic lubrication and have proved that adapted shapes and geometries can improve the performance of lubricated contacts. A hydrodynamic model was developed by assuming the roughness of the textured surface and considering the cavitation in a steady-state regime. The proposed model was validated and compared with the analytical model of Fowell et al. [1]. Three different textures shapes were considered. The results showed that the rough-textured thrust affects the hydrodynamic performance significantly. Thus, by increasing the arithmetic roughness of textured surfaces, the hydrodynamic pressure, and the lifting force increase depending on the texture shape. A rougher surface slightly increases the friction force for the three considered textures.
Evaluation of Velocity and Acceleration Effect on Mecanum Wheel Robot Positioning
Authors: Bączyk Aleksander , Wojtowicz Przemysław , Klekiel Tomasz
Published: August 2022

In this paper, a Mecanum wheel omnidirectional robotic platform made for taking measurements in harsh and dangerous conditions is introduced. Due to the necessity of highly accurate displacement of the platform for measuring the conditions at the exact measurement point and due to known Mecanum wheel slippage and relatively poor position accuracy, a calibration procedure for minimizing positioning error had to be implemented. For this task, a highly accurate stereographic digital image correlation (DIC) system was used to measure platform displacement. A series of parameters, namely linear maximum velocity and acceleration/deceleration values, were taken into account during the calibration procedure to find the best combination allowing precise movement of the robot. It was found that low acceleration values were the main causes of the robot’s poor positioning accuracy and could cause the robot’s motors to stall. Max speed values proved to have little effect on the robot’s positioning.
Tensile Fault Dislocation in an Irregular-Layered Elastic Half-Space
Authors: Savita  , Sahrawat Ravinder Kumar , Malik Meenal
Published: August 2022

In the present paper, an analytical solution for the static deformation of a two dimensional model consisting of an infinite homogeneous isotropic elastic layer of uniform thickness placed over an irregular isotropic elastic half-space due to movement of a long tensile fault has been obtained. The rectangular shaped irregularity is assumed to be present in the lower half-space and assuming that the fault lies in the elastic layer at a finite depth say ’h’ to the upper surface of the layer. For numerical computation, the expressions of displacements and stresses are calculated by using Sneddon’s method and the effect of source depth and irregularity on the displacements and stresses has been investigated graphically.

Introduction

An analysis of samples originating from domestic and exotic animals from Lower Silesia but also from other parts of Poland was carried out based on research conducted in 2014–2017.

Material and Methods

The materials used for the study were 11,338 tumour samples taken in vivo during surgery and as biopsies and posthumously during necropsies. They were sent to the Department of Pathology at Wrocław University of Environmental and Life Sciences for histopathological diagnosis.

Results

The largest group were canine tumours, of which there were 9,745 (85.95%), followed by feline tumours, totalling 1,397 (12.32%), tumours from exotic animals (186; 1.64%), from horses (7; 0.06%), and from cows (2; 0.02%). A significant number of cases of animals suffering from more than one tumour were also found, which had not been frequently diagnosed previously.

Conclusion

The number of neoplasms diagnosed in pets and exotic animals is increasing every year. The average animal age at diagnosis continues to fall. The greatest number of neoplasms were diagnosed in mixed-breed dogs and cats, and the number of tumours in a pure breed strictly correlated with breed’s popularity in the research period. Mesenchymal tumours are still the most prevalent type of tumours in dogs, while in cats epithelial tumours predominate. The neoplasm case pattern in animals conforms to that in humans in the same area.

The study examined the moderating effect of institutional ownership on relationship between audit tenure, audit independence, board independence and audit quality of listed deposit money banks (LDMBs) in Nigeria. The study population comprises 14 LDMBs on the Nigerian Stock Exchange as at 31st December, 2020. 13 LDMBs were used as sample of the study. Logit regression technique was used as a tool of data analysis. Findings of the study revealed that, in the direct relationship, audit independence, board independence and institutional ownership have significant effect on the audit quality of LDMBs in Nigeria. The finding of the moderated model of the study reveals that institutional ownership has a significant negative moderating role on the relationship between audit tenure, audit independence, board independence and audit quality of LDMBs. It is therefore recommended among others that listed deposit money banks in Nigeria should ensure that they consider long-term institutional shareholding since those with a long-term stake have the motivation to monitor management and thereby, requesting a better audit quality through BIG4 auditors.
