Authors: Ingle Vijaya Manikrao , Kale Lata M. , Gawai Amol S. , Jain Hitendra R. , Mhaske Rupali V.
Published: June 2022

Context:

Pfeiffer in 1938 observed the crystallization pattern of cupric chloride on admixture with blood of cancer patient. Most of the oral squamous cell carcinoma develops from potentially malignant disorders (PMDs).

Aim:

The aim of this study is to validate the efficacy of crystallization test in screening of oral PMDs.

Setting and Design:

The study was carried out in the Department of Oral Medicine and radiology and oral Pathology and Microbiology.

Methods and Material:

The study included 20 oral PMDs and 20 normal healthy participants. One drop of blood was collected and dilution of 6% hemolyzed blood was done; 0.1 to 0.2 cc of this blood sample is added to 10 cc of 20% cupric chloride solution and further is subjected to crystallization test.

Statistical Analysis Used:

The Chi-square test was applied and “P” value was found to be significant. This indicates that crystallization test was statistically significant for the detection of oral PMDs.

Results:

In this study, sensitivity 85% and specificity 90% of crystallization test in screening PMDs was observed. Among 20 PMDs, 17 were positive and 3 were negative and among 20 normal cases, 18 were negative, and 2 were positive for the crystallization test. Positive predictive value and negative predictive value was found to be 89.47% and 85.47% respectively.

Conclusion:

This test is simple, less invasive, economical and can be used at the community level in mass screening of high-risk individuals more prone to develop potentially malignant oral lesions.
Therapeutic Assessment of Intralesional Corticosteroids and Ultrasound Therapy in Management of Oral Submucous Fibrosis
Authors: Parikh Shilpa J. , Parmar Priyanka R. , Shah Jigna S.
Published: June 2022

Background:

Oral submucous fibrosis (OSMF) is a premalignant condition with a chronic, debilitating, and resistant nature. Various treatment modalities have been proposed for this condition including steroid injections and surgical interventions. In literature, there are very few studies signifying the role of therapeutic ultrasound in OSMF and this still remains a hidden field which needs to be explored further.

Aims and Objectives:

To evaluate and compare the clinical efficacy of ultrasound therapy with and without physical exercise with intralesional injection (I/L) of 2 ml dexamethasone (4 mg/ml) + hyaluronidase 1500 IU with physical exercise in patients with OSMF.

Materials and Method:

A total of 30 patients with OSMF were selected irrespective of age and gender and were allocated into groups A, B and C randomly.

Group A:

10 patients treated with I/L injection of dexamethasone and hyaluronidase with physical exercise.

Group B:

10 patients treated with therapeutic ultrasound and soft tissue mobilization with physical exercise.

Group C:

10 patients treated with therapeutic ultrasound and soft tissue mobilization without physical exercise. All the patients were evaluated weekly for 1 month and findings were compared with those at the beginning of treatment.

Result:

Ultrasound in combination with exercises leads to more improvement in mouth opening compared to ultrasound alone. Improvement in mouth opening of ultrasound with exercise was almost similar to intralesional injection of steroids.

Conclusion:

Ultrasound therapy interventions definitely show a significant improvement in the patient's condition with no reported side effects; hence it should be included in the treatment protocol for patients with OSMF.
Therapeutic Evaluation of 5% Topical Amlexanox Paste and 2% Curcumin Oral Gel in the Management of Recurrent Aphthous Stomatitis- A Randomized Clinical Trial
Authors: Gauthaman Jeevitha , Ganesan Anuradha
Published: June 2022

Background:

Recurrent aphthous stomatitis (RAS) minor is a painful oral condition that is characterized by shallow ulcers with an erythematous halo. These ulcers cause difficulty in mastication and speech and have a high recurrence rate.

Objective:

The present study aims to compare the size of the ulcer, erythema, pain score, and recurrence rates in patients using 5% topical amlexanox and 2% curcumin oral paste in the management of RAS minor.

Materials and Methods:

The present study was conducted among 48 participants who were randomly assigned into two groups. Group A comprised participants who were given 5% topical amlexanox paste and Group B comprised participants who were given 2% curcumin oral gel for application. The participants were evaluated on days 1, 4, and 7 for the size of ulcers, erythema level, and pain score. They were reviewed on days 30, 60, 90, and 180 and recurrence episodes were documented.

Results:

There was a significant reduction in erythema (0.041) and pain scores (0.012) in Group B participants who used curcumin. The size of the ulcer had reduced in both the groups though there was no significance. Recurrence rates were high in participants who used amlexanox (92%) and were comparatively low in the curcumin using group (50%).

Conclusions:

Curcumin is a potent, safe substitute in the management of RAS minor for its effectiveness in reducing erythema, pain, and recurrence rates. Further studies should be conducted for evaluating the efficacy of curcumin in various clinical types of RAS.

Authors: Mondal Binindita , Vaishali M. R. , David Maria P. , Roopashri G. , Kumar Vinod , Ponnuswamy Indira A.
Published: June 2022

Background:

Personal identification is crucial in natural mass disasters and in man-made disasters when the body is highly mutilated and fragmented. The mastoid process of the skull is important in this regard for sex determination, since it is one of the most protected region and is resistant to damage.

Aim:

To assess the usefulness of morphometric and volumetric analysis of the mastoid process for gender determination in forensic odontology.

Materials and Methods:

The study comprised of 60 retrospective CBCT skull images (30 males and 30 females) of known sex within the age group of 17–65 years. Radiographic measurements of the length, width, height and volume of the right and left mastoid processes were made using customized software.

Statistical Analysis:

The Wilcoxon signed-rank test, the Mann–Whitney U test, and discriminant functional analysis (DFA) were used to analyze all the collected data.

Results:

In the present study, the mean values of length, height, width and volume of the mastoid process were found to be higher in males than in females. The height of the mastoid process was found to be a good indicator of gender determination, with a sensitivity of 76.7%, a specificity of 76.7%, and an overall accuracy of 76.7%.

Conclusion:

We conclude that the mastoid process is a good indicator of gender determination. The volume can also be included as an additional parameter along with length, height, and width. We therefore recommend the use of the mastoid process for gender determination in personal identification in forensic odontology.

Published: June 2022

In recent decades and an aging society, the prevalence of special needs dental patients has increased noticeably both in children and adults. In most dental patients, the dental radiograph is one of the essential diagnostic tools that help make the proper diagnosis and treatment plan. In this article, we report two cases of special needs patients; aging, bedridden, and teenage autism. In the first case, the periapical bisecting-angle and occlusal topographic radiography were taken with the patient on the mobile hospital bed. In the second case, the oblique lateral radiographs were performed for diagnosis of third molar impaction. The principle of periapical bisecting-angle, occlusal topographic, and oblique lateral radiography is also reviewed.

Authors: Jha Snehjyoti , Sangamesh NC , Bhuvaneshwari S. , Mishra Silpiranjan , Bajoria Atul A. , Sikdar Abhik
Published: June 2022

Context:

Oral submucous fibrosis (OSMF) is a chronic debilitating disease with significant malignant potential. The most common symptoms of the condition include burning sensation, trismus, swallowing, and speech impairment as well as gustatory alteration.

Aims:

The aim of the study was to evaluate and compare the efficacy of gustatory functions in oral submucous fibrosis patients, gutka chewers, chronic smokers and healthy individuals.

Methods and Material:

A total of 112 individuals were selected for the study and divided into four groups of 28 participants, each comprising OSMF patients, gutka chewers, chronic smokers with gutka-chewing habits, and healthy individuals. Each participant was assessed for gustatory function using four different tastants for sweet, sour, salty, and bitter, and the taste perception was recorded as hypogeusia, hypergeusia, dysgeusia, and ageusia.

Statistical Analysis Used:

Data obtained were analyzed with SPSS software version 26. A comparison between the four groups was made separately for the four different tastes and the five parameters. A P value of ≤0.05 was considered statistically significant.

Results:

For OSMF patients, gutka chewers, and chronic smokers with gutka-chewing habits, salty taste showed normal perception, sweet taste showed hypogeusia, and bitter taste reported ageusia. The healthy individuals mostly showed normal perception for almost all tastes.

Conclusions:

It can be concluded that OSMF and habitual consumption of areca nut and tobacco appear to have a significant impact on the alteration of the gustatory function, although the type of taste sensation that is affected may vary from person to person.

Authors: Ignatius Ancy V. , Garlapati Komali , Chaitanya Nallan CSK , Saba Asra , Kandi Pallavi , Reddy Chelluri Shreya
Published: June 2022

Background:

Temporomandibular disorders (TMDs) constitute clinical problems that involve the masticatory muscles, the temporomandibular joints, associated structures, or both. The etiology of TMDs is multifactorial. The association between occlusal interferences and TMD is controversial..

Objectives:

This study is designed to evaluate the clinical outcome of T-Scan guided occlusal equilibration in patients suffering from TMD associated with occlusal discrepancies.

Materials and Methods:

A total of 15 patients clinically diagnosed with TMD based on the Diagnostic Criteria for Temporomandibular Disorders and with positive occlusal interferences were included in the study. The occlusal equilibration was achieved by performing T-Scan guided Immediate Complete Anterior Guidance Development.

Results:

The obtained data was subjected to statistical analysis using SPSS version 20.0 software. There was a statistically significant reduction in the occlusion time, i.e., from 0.77 ± 0.6 pre-treatment to 0.31 ± 0.2 post-treatment (P = 0.005), and also disclusion time, i.e., from 1.71 ± 1.09 pre-treatment to 0.11 ± 0.03 post-treatment (P = 0.000). There was a statistically significant reduction in the VAS score post-treatment (P = 0.000).

Conclusion:

T-Scan guided occlusal equilibration in TMD patients has resulted in significant improvement of symptoms. Hence, we emphasize the importance of the identification and correction of occlusal interferences in the management of symptomatic TMDs.

Authors: Harika Naidu , Sridevi Koduri , Krishnaveni Buduru , Kumar Nalli Prasanth , Mounika Gutta , Naga Deepika Adari Devi
Published: June 2022

Background:

HIV is a life-threatening disease that increases morbidity and mortality due to the alterations of the body's immune system, leading to several opportunistic infections due to the progressive loss of CD4+ T lymphocytes.

Aim:

To identify and correlate the Candida strains with CD4+ count in Human Immunodeficiency Virus (HIV) patients on Highly active antiretroviral therapy (HAART) and evaluate the in-vitro susceptibility to fluconazole and voriconazole.

Materials and Methods:

A total of 100 HIV-positive patients who were not under HAART therapy were examined at three different intervals for the presence of Candida strains along with their CD4+ count and evaluated for in-vitro susceptibility to fluconazole and voriconazole. The obtained values were analyzed using the Spearman correlation test and Chi-square tests with a significant P value of 0.005 and SPSS version 20.0 software.

Results:

C. albicans was the most common species isolated, followed by C. krusei, C. glabrata, and C. tropicalis. C. glabrata showed a positive correlation with CD4+ count at 6 months of HAART therapy. The variation in CD4+ count prior to HAART therapy and at 3 and 6 months of HAART therapy showed a significant increase in the CD4+ count. Antifungal susceptibility testing showed that all Candida strains were resistant to fluconazole and susceptible to voriconazole.

Conclusion:

The correlation of CD4+ count with Candida strains and in-vitro susceptibility of voriconazole to all the identified strains of Candida as observations from the present study suggests the need for more periodic studies among different sample populations with larger sample size.

Reverse smoking is a unique style of tobacco use in which the smoker places the lit end of a chutta into his or her mouth while smoking and then inhales the smoke from the lit end. The purpose of this scoping review is to explore reverse smoking and identify its effects among Indian reverse smokers. Literature search was conducted using PubMed, PubMed Central, Embase, and CINAHL Plus. Boolean operators AND/OR was used with the search terms. Search was limited to the original research articles, English language articles, and full-text articles. Finally seven original articles were selected for the scoping review. The studies were conducted between 1971 and 2016, where more studies were identified in the 21st century (2002–2016). Four themes emerged from the data analysis. The first themes explore the palatal mucosal changes in reverse smokers; the second theme presents carcinoma and reverse smoking; third theme focuses on effects of keratinization on detection of epithelial atypia, and lastly, the fourth theme focuses on reverse smoking and psychosocial factors. Reverse smokers are more likely to develop precancerous palatal alterations and squamous cell carcinoma of the palate. To make healthy choices, a strong focus on health promotion is required, which includes initiatives that emphasize the need of educating individuals about disease risks.

Published: June 2022

Obesity is a growing worldwide health hazard that is characterized by excess malnutrition. Excess food intake leads to dysregulated energy homeostasis and increased adiposity, activating pro-inflammatory physiologic pathways that can contribute to the chronic inflammatory state associated with many chronic illnesses. Obesity is a preventable illness, but its multifaceted etiology, including genetic, behavioral, and environmental variables, is critical to understanding its epidemiology and pathophysiology. Obesity is a critical predisposing factor for illnesses including type II diabetes, cardiovascular disease, and cancer, with higher morbidity and death. Obesity rates are rising, and so will the need for perioperative anesthesia for subjects with obesity. Obesity epidemiology, biochemistry, and pathophysiology are significant concepts in perioperative anesthesia management for subjects with obesity. To provide optimal intraoperative care for subjects with obesity, preoperative cardiovascular assessment for coronary artery disease and drug monitoring is required. Individuals suffering from obesity have significantly higher oxygen consumption rates and a higher risk of desaturation and surgical complications. Individuals suffering from obesity require specialized perioperative treatment related to higher prevalence of perioperative complications.

Authors: Tesoro Rosa , Hagerman Andres , Molliqaj Granit , Ellenberger Christoph , Licker Marc
Published: June 2022

The administration of glucose-insulin-potassium (GIK) has demonstrated cardioprotective effects in cardiac surgery. A 58-year-old male with severe disabling back pain due to posterolateral lumbar pseudarthrosis was scheduled for spine surgery. He previously experienced two episodes of acute coronary syndrome that required percutaneous coronary interventions (PCIs). Coronary angiogram showed intrastent occlusions and multiple coronary lesions that were not suitable for percutaneous or surgical revascularization. During pharmacological stress imaging, myocardial ischemia developed in 19% of the ventricular mass and was reduced to 7% when GIK was administered. After anesthesia induction, the GIK solution was also infused and surgery was uneventful, with no signs of postoperative myocardial injury. Four days later, the patient was successfully discharged to a rehabilitation center. This is the first clinical report of GIK pretreatment during non-cardiac surgery in a patient with ischemic heart disease (IHD).
Patients with sleep-disordered breathing for bariatric surgery
Authors: Oh Matthew W. , Chen Joy L. , Moon Tiffany S.
Published: June 2022

The prevalence of patients with obesity continues to rise worldwide and has reached epidemic proportions. There is a strong correlation between obesity and sleep-disordered breathing (SDB), and, in particular, obstructive sleep apnea (OSA). OSA is often undiagnosed in the surgical population. Bariatric surgery has been recognized as an effective treatment option for both obesity and OSA. Laparoscopic bariatric procedures, particularly laparoscopic sleeve gastrectomy (LSG), have become the most frequently performed procedures. OSA has been identified as an independent risk factor for perioperative complications and failure to recognize and prepare for patients with OSA is a major cause of postoperative adverse events, suggesting that all patients undergoing bariatric surgery should be screened preoperatively for OSA. These patients should be treated with an opioid-sparing analgesic plan and continuous positive airway pressure (CPAP) perioperatively to minimize respiratory complications. With the number of bariatric surgical patients with SDB likely to continue rising, it is critical to understand the best practices to manage this patient population.

Published: June 2022

The dream is now real! We had started thinking of establishing “Bariatric Anesthesia Fellowship” (BAF) program in our setting since 2012. The reason was the increasing number of bariatric surgical cases for weight loss under general anesthesia (GA). The journey till establishing the BAF program consisted of two phases. Phase I started in 2012 to establish clinical practice guidelines (CPG) in “Anesthesia for Patients with Morbid Obesity undergoing weight loss surgery”. Phase II started in 2015 to establish BAF program. In 2021 the first draft of BAF program was submitted to the medical education for approval. In March 2022, we got the interim approval of the program. Though the journey took sometime but ultimately it ended with success and achieving the dream. In this review, we are going to discuss a roadmap consisted of two phases in an attempt to reach our goal of establishing the BAF program.

Published: June 2022

Bariatric surgeries are effective long-term management for morbid obesity with its adverse sequelae. Anesthesia of bariatric surgeries poses unique challenges for the anesthesiologist in every step starting with vascular access till tracheal extubation. The usage of ultrasound in anesthesia is becoming more prevalent with a variety of benefits, especially in the obese population. Ultrasound is successfully used for obtaining vascular access, with more than 15 million catheters placed in the United States alone. Ultrasound can also be used to predict difficult intubation, as it can confirm the tracheal intubation and assess the gastric content to prevent pulmonary aspiration. Ultrasound is also used in the management of mechanically ventilated patients to monitor lung aeration and to identify respiratory complications during positive pressure ventilation. Moreover, intraoperative echocardiography helps to discover the pulmonary embolism and guides the fluid therapy. Finally, ultrasound can be used to perform neuraxial and fascial plane block with a less overall time of the procedures and minimal complications. The wide use of ultrasound in bariatric anesthesia reflects the learning curve of the anesthesiologists and their mounting efforts to provide safe anesthesia utilizing the updated technology. In this review, we highlight the role of ultrasonography in anesthesia of bariatric surgery and discuss the recent guidelines.

Published: June 2022

Obesity is no longer a disease of the affluent. The prevalence of obesity has risen at an exponential rate globally, with an increasing burden on healthcare resources. Perioperative management of patients with morbid obesity is known to be challenging, and this is particularly so in the management of their airway, a crucial procedure that requires meticulous planning and modifications. Anesthesiologists will expect to see more patients with obesity in their practice presenting for both bariatric and non-bariatric surgery, or even for emergency surgery. Hence, any generalist anesthesiologist should be confident in managing such a patient, with the appreciation that these patients often pose a significant challenge to the practice of anesthesia. This article describes different techniques and looks at the evidence for airway management in the morbidly obese. Other aspects of perioperative management of such patients are beyond the scope of this article.
Task Scheduling Techniques for Energy Efficiency in the Cloud
Authors: Kak Sanna Mehraj , Agarwal Parul , Alam M. Afshar
Published: June 2022

Energy efficiency is a key goal in cloud datacentre since it saves money and complies with green computing standards. When energy efficiency is taken into account, task scheduling becomes much more complicated and crucial. Execution overhead and scalability are major concerns in current research on energy-efficient task scheduling. Machine learning has been widely utilized to solve the problem of energy-efficient task scheduling, however, it is usually used to anticipate resource usage rather than selecting the schedule. The bulk of machine learning approaches are used to anticipate resource consumption, and heuristic or metaheuristic algorithms utilize these predictions to choose which computer resource should be assigned to a certain activity. As per the knowledge and research, none of the algorithms have independently used machine learning to make an energy-efficient scheduling decision. Heuristic or meta-heuristic approaches, as well as approximation algorithms, are frequently used to solve NP-complete problems. In this paper, we discuss various studies that have been used to solve the problem of task scheduling which belongs to a class of NP-hard. We have proposed a model to achieve the objective of reduced energy consumption and CO2 emission in a cloud environment. In the future, the model shall be implemented in MATLAB and would be assessed on various parameters like makespan, execution time, resource utilization, QoS, Energy utilization, etc.

Some patients with visceral leishmaniasis (VL), or kala-azar, suffer relapses and low quality of life despite adequate drug therapy, especially those co-infected with HIV. Occasionally, physicians indicate splenectomy, but the benefit of the procedure needs to be analyzed systematically. Therefore, a retrospective open cohort study was conducted in Teresina, Brazil. Inpatients from a reference hospital with relapsing VL who had a rescue splenectomy between 2012 and 2019 after the nationally recommended drug therapy failed were studied. The procedure’s risks and benefits were assessed in a limited-resource setting. The primary outcomes were surgical complications, complete blood count, CD4+ cell count, hospitalizations, survival time, and medical complications preceding death. Thirteen adult patients received medical and surgical indications of splenectomy (12 men and one woman). Eleven had HIV infection. Two had early and two had late complications. Four died, all of whom were infected with HIV. An additional HIV-coinfected patient, apart from the cohort, died just before surgery. The death rate after surgery was 13.3 overall and 22.1 per 100 person-years among HIV-infected patients (31% overall and 36%, respectively). The impressive rise of complete blood counts and reduction of blood transfusions and hospitalizations were observed among all patients. Also, a meaningful increase in CD4+ cells in HIV-infected patients was noted. Splenectomy may benefit patients with relapsing VL. However, before performing splenectomy, available combined drug therapy for VL should be tried.

Published: June 2022

Dengue in Paraguay is an endemic disease of public health importance. Several studies suggest that an increased density of Aedes aegypti and the presence of dengue cases may be associated with climatic conditions. This study aimed to establish the phenotypic variations of Ae. aegypti from four cities (Asunción, Itauguá, Minga Guazú, and Ciudad del Este) and the potential association of environmental variables with the number of eggs in capture sites. Eleven morphometric phenotypic characters were evaluated, and environmental data were obtained from Earth Engine and local meteorological stations. An analysis was carried out using principal component analysis and linear discriminant analysis, and we estimated the correlation using [relative humidity, Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI)] between variables and the number of eggs in each site. Differences in mean NDVI and NDWI between cities and their relationship with the morphometric performance of individuals were also assessed. The study demonstrated morphometric variations between the populations of Ae. aegypti from two ecoregions, with the Litoral ecoregion populations presented a greater phenotypic variation than those observed in the Alto Paraná ecoregion. Significant statistical associations were registered between the number of eggs with relative humidity (r = –0.45) and the NDVI at 100 meters from the capture points (r = –0.61) for Minga Guazú, and with the NDWI at 100 meters (r = 0.54) for Ciudad del Este. Future studies on these Ae. aegypti populations, and its dispersion could contribute to improve vector control measures and foster future genetic studies.

Published: June 2022

Melioidosis is reported to cause a high fatality rate in children, even in the absence of risk factors for disease. The aim of this study was to identify characteristics of fatal pediatric melioidosis infection. We performed a retrospective analysis of children aged < 15 years with culture-confirmed melioidosis admitted to Bintulu Hospital in Sarawak, Malaysian Borneo, from January 2011 to December 2020. Forty-one children had culture-confirmed melioidosis. Nine (22%) had a fatal outcome; 8 (89%) had no predisposing risk factors. Bacteremia, septic shock, and acute respiratory distress syndrome were present in all fatalities. Demographic characteristics, presenting manifestation, and disseminated infection were not significantly associated with mortality, whereas the presence of splenomegaly, cytopenia, disseminated intravascular coagulation, and hepatobiliary dysfunction, all of which are features of hyperferritinemic sepsis-induced multiple-organ dysfunction syndrome, were associated with mortality. Hyperferritinemic sepsis-induced multiple-organ dysfunction syndrome may be a key component in the pathogenesis of fatal pediatric melioidosis.
Pedometre, GNSS ve IMU ile Mesafe Ölçüm Doğruluğunun Tespit Edilmesi ve Yeni Geliştirilen İvme Sensörü Temelli Yöntem
Authors: ACAR Uğur
Published: June 2022

Konum belirleme uygulamaları, son yıllarda mobil telefonlarının da konum belirleyebilmesi kabiliyetini edinmesi ile yaygınlaşmaya başlamıştır. Genel olarak GNSS ile konum belirleme yöntemleri kullanılırken, kapalı alanda GNSS sisteminin verimli olarak çalışmaması neticesinde, konum belirleme için başka yöntemler geliştirilmesi çabası içine girilmiştir. Yaygın olarak yerel ağlar kurmak ve bu yerel ağlar ile mesafeler ölçerek konum belirlemek bu yöntemlerin temel çalışma prensibidir. Bunun için, Bluetooth, kablosuz ağlar ve değişik frekanslara sahip sinyaller, ses ötesi sinyaller, radyo frekansları ile çalışan RFID modülleri vb. sistemler kullanılmaktadır. Hem gerçek zamanlı veriler üretilebilmekte hem de üretilen veriler sunuculara kaydedilerek saklanabilmekte ve daha sonra kullanıcılar hizmetine sunulmaktadır. Kullanılan teknolojiye göre yüksek ve orta konum doğruluğuna sahip veriler elde edilebilmektedir. Ancak bu sistemlerin ağ oluşturma gereksinimi yüzünden yüksek maliyetli olması ve açık alanlarda sonuç üretememesi yüzünden özellikle spor uygulamalarında IMU temelli sadece mesafe ölçen çözümlerin oluşturulmasına neden olmuştur. Sunulan makalede, konum belirlemenin temeli olan mesafe ölçümünün yüksek doğrulukta sadece ivme sensörü kullanılarak elde edilmesine yönelik yöntem ve filtreler geliştirilmiştir. Elde edilen sonuçlar, diğer mesafe ölçme yöntemleri ve gerçek mesafe ile kıyaslanmıştır. Geliştirilen filtreler, değişken adım uzunluğu tespiti ile mesafe ölçümü hesabına dayalı olarak, yanlış adım tespitini engellemek, statik hareketleri filtrelemek ve genel olarak ivme sensörünün gürültülerini azaltarak doğru mesafeyi hesaplamak amacıyla geliştirilmiştir. Filtreler kullanılmadan ivme sensörü ile elde edilen mesafede hata miktarı %60’lara ulaşırken, geliştirilen yöntem ile hata miktarı %2’nin altına düşmüştür. Bu sonuçlar, geliştirilen yöntemin mesafe ölçümünde ve metre altı konum belirlemede kullanılabileceğini açıkça göstermiştir.

Authors: Chaplyhina Angela B. , Yuzyk Diana I. , Savynska Nadiia O. , Hramma Viktor M.
Published: June 2022

The diet composition of collared flycatcher nestlings, Ficedula albicollis (Temminck, 1815), in the transformed forests of northeastern Ukraine was investigated to present an argument for conservation management actions that could benefit the species. Food pellets were collected from nestlings in four study sites with differing levels of recreational disturbance over 10 breeding seasons. The invertebrates they contained were identified, divided into trophic groups and compared across sites. A total of 1,160 food pellets were collected, containing 3,253 invertebrates from 294 species. Insects comprised 83% of the prey, with the most abundant orders of Diptera, Coleoptera and Lepidoptera. The smallest diversity of prey species was found in samples from the most disturbed site. The qualitative composition of the prey items showed that zoophages were the most frequent trophic group encountered, followed by phytophages, saprophages, polyphages, and necrophages. However, the order of trophic group frequency varied between sites. Although collared flycatchers forage within a limited area, their diet is characterized by a wide diversity of prey, and they exploit all forest layers. Key words: collared flycatcher, diet, trophic links, zoophages, phytophages, saprophages, necrophages, polyphages

Authors: Singh Keshav , Fatima Nishat
Published: June 2022

One of the most promising approaches to address the worldwide water crisis is wastewater treatment and utilization. Vermifiltration is a novel wastewater treatment method that involves using composting earthworms to remediate contaminated water. It is considered as an innovative technology that offers a long-term strategy for wastewater treatment with simultaneous sludge reduction and remediation. The treatment capacity parameters by vermifilter of wastewater has a strong association with earthworm activity. It's a biofilter in which the earthworms breakdown the suspended particles trapped on the filter bed, decompose organic matter via enzymatic activity, and aerate the system through burrowing action while removing pathogens. The present review focuses on vermifiltration and the mechanisms underlying it, as well as the current situation of the technology for the treatment and reutilization of pollutants produced in domestic and industrial fields.

So, it is obligatory to find out a competent contractor among all, for the successful completion of the work. Construction bidding is the process of offering a proposal to undertake a construction project. And it is one of the methods for the selection of a contractor. Bidding strategies vary from contractor to contractor and each contractor has a different view of the factors affecting their bid decisions. This study aims to find an effective strategy for the selection of competent contractors and bid evaluation. There are many factors that influence the bidding strategy. These factors influence depend on the situation when the research is done.

Canine Visceral Leishmaniasis (CVL) is a disease caused by the protozoan genus Leishmania and transmitted by the bite of the sand fly mosquito. It is considered a zoonosis and its control is based on the diversity of urban vector reservoir agents, where dogs are the main reservoirs of the parasite. The present article aimed to investigate the prevalence and incidence of CVL in different regions of Brazil, from a literature review. An analysis of scientific articles focusing on the epidemiological, clinical, diagnostic, prophylaxis and control aspects of the disease was carried out. The prevalence of CVL in Brazilian regions is determined by means of clinical, epidemiological and laboratory diagnostic methods. Laboratory confirmation is necessary to avoid false positive results, whose consequences can be fatal, such as euthanasia in non infected animals. The study is based on the survey of transmission areas with the evaluation of the effectiveness of actions to control and progress the disease, such as the reduction of prevalence and lethality, with measures of interventions and environmental sanitation that can reduce its incidence. It was found that the knowledge of the epidemiological indicators of CVL are essential to implement health actions to promote control and prevention in susceptible populations.

The climate of Brazil is predominantly tropical, which favors the high prevalence and
incidence of hemoparasitosis such as Erliquiosis and Anaplasmosis. transmitted by ticks, especially the brown tick of the species Rhipicephalus sanguineus. Thus, considering the seasonality, the Uberlândia region favors the development of ectoparasites, especially the "brown" tick of the species Rhipicephalus sanguineus, the agent that transmits these diseases. The present article aimed to investigate the prevalence, incidence, morbidity, lethality and mortality caused by Erliquiosis and Anaplasmosis of cases seen in a veterinary clinic in Uberlândia, in the period between May 09 and October 23, 2021. Hemoparasitosis was confirmed in 46.87% of the suspected animals, and Ehrlichia canis was identified in 12 animals (80%), with a prevalence of 2.29%. Anaplasma platys was identified as the pathogen responsible for the disease in 3 animals (20%), with a prevalence of 0.76%. There was no evidence of high mortality rate in positive animals, which may be related to the early diagnosis of the disease. It was possible to conclude that the hemoparasitoses Erliquiosis and Anaplasmosis are diseases that are becoming more prevalent in the clinical routine.
ANÁLISE CRÍTICA DE TRANSITIVIDADE DE REPRESENTAÇÕES DISCURSIVAS DO MINISTRO DA ECONOMIA PAULO GUEDES SOBRE PRIVATIZAÇÃO
Authors: Tavares da Silva Emmannuel Alexandre , Silva Bezerra Fábio Alexandre
Published: June 2022

Tendo em vista a influência que o discurso como prática e evento social exerce nas representações e nas relações em sociedade, este artigo objetiva analisar o discurso do ministro da economia Paulo Guedes em entrevista concedida à CNN Brasil em novembro de 2020. Para isso, adotamos uma perspectiva crítica a partir da Análise Crítica do Discurso (ACD) e utilizamos conceitos e categorias de análise da Gramática Sistêmico-Funcional (GSF) de Halliday e Matthiessen (2014), mais especificamente o sistema de TRANSITIVIDADE. Em seguida, utilizamos a perspectiva de Fairclough e Fairclough (2012) para investigarmos como as representações advindas das realizações discursivas contribuem para a construção de um processo de legitimação argumentativa, com especial atenção para potenciais características de hegemonização neoliberal no Brasil presentes no discurso do ministro. Os resultados apontam que as representações construídas pelo ministro são utilizadas como ferramentas de materialização e construção dos atores representados negativamente como sendo ameaças tangíveis e reais. Nesse sentido, participantes representados negativamente, usualmente na posição de Ator, são encontrados quando construídos como prejudiciais, ao passo que o governo, na posição de Meta em relação a tais processos e atores, é construído como vítima. Sobre a argumentação prática, demonstramos que a estrutura da fala analisada se apresenta sólida dentro da perspectiva utilizada, exceto pela falta dos componentes “contra-argumento” e “consequências negativas”. Por fim, acerca da questão dos traços ideológicos econômicos, encontramos duas principais características: privatização de empresas estatais e procura de controle de dívida por meio dessas privatizações.
PARADOXO DO BILDUNGSROMAN MODERNISTA:
Authors: Albus Maria Lua , Felix José Carlos
Published: June 2022

Este artigo analisa o romance Filhos e Amantes (Sons and Lovers, 1913), de D. H. Lawrence, e sua versão cinematográfica de mesmo nome (1960), dirigida por Jack Cardiff, partindo da hipótese interpretativa de que a focalização dupla por Paul e Gertrude, estruturalmente amalgamados pelo texto do narrador, resulta em conarrativas indicativas do paradoxo da forma do Bildungsroman — circunscrito na tensão indecidível e ao mesmo tempo suplementar entre individualidade e coletivismo, tradição e experimentação. Por meio de uma leitura cerrada de excertos do romance e cenas do filme, discutimos como a dupla focalização resulta em uma aporia que inscreve em Filhos e Amantes uma dimensão de transgressão das convenções desse gênero na notável busca pelo experimentalismo característico do modernismo literário em língua inglesa. Os estudos narratológicos de Bal (2009), estilísticos de Leech e Short (2007), cinematográficos de Bordwell e Thompson (2013) e Bazin (1997), e intermidiáticos de Rajewsky (2005) fundamentam a análise estrutural dos objetos, enquanto Adorno (2012a, 2012b), Beards (1974) e Jeffers (2005) embasam a discussão acerca das convenções e transgressões sobre o romance de formação perpetradas por Lawrence e Cardiff.

Introduction. Carrying out studies of the toxicity of combustion products (HCL50) of polymer materials: epoxy glue grade EK-5T and compound ELPLAST-180 ID according to GOST with the additional use of gas chromatography with mass selective detection. Objective. Experimental study of the toxicity of combustion products (HCL50) of polymer materials in various modes of thermal oxidative degradation: epoxy glue grade EK-5T and compound ELPLAST-180 ID, as well as a survey mass spectrometric analysis of products of thermal oxidative degradation. Material and methods. The studies were carried out in accordance with GOST 12.1.044-89. Equipment: “Toxicity” unit, “Infracar M2.01” gas analyzer, Focus GC chromato-mass-spectrometric instrumental complex with DSQ II mass spectrometer (Thermo Scientific, USA), Nova Medical Stat Profile automatic analyzer of blood gases, electrolytes and oximetry Model CCX (USA). Blood sampling was carried out in capillaries “Stat Profile Critical Care Express Capillary Tube 230 µL with Na Heparin” LOT 107669, CO2 chamber. Results. In the course of studying the products of outgassing of polymer materials using an exposure chamber and a gas chromatomass spectrometer, a significant increase in toxicity (4.8 times) of a mixture of chemicals released from epoxy glue EK-5T during the transition from thermal-oxidative decomposition (smoldering) to flame combustion was established. The toxicity index of the combustion products of the ELPLAST-180 ID compound under the same conditions increases by 1.8 times. A linear dependence of the percentage of lethality of laboratory animals on the integral indicator of the toxicity of combustion products has been established. Limitations. Studies of the toxicity of combustion products were carried out on non-metallic materials: epoxy glue EK-5T, compound ELPLAST-180 ID. These materials are planned to be used in hermetically sealed objects of the Navy. Conclusion. The expediency of using gas chromatography-mass spectrometry for assessing the combined effect of combustion products is shown.
Manuel Carranza Vargas y la pintura histórica en Costa Rica
Authors: Araya Incera Manuel
Published: June 2022

El ensayo aborda la pintura histórica como uno de los géneros preeminentes del arte pictórico. Como recurso visual, la pintura histórica cuenta una historia y constituye un medio alternativo al discurso escrito o hablado propio del historiador. En Costa Rica el género de la pintura histórica ha sido muy escasamente desarrollado. A finales del siglo XIX figuran en este género Lorenzo Fortino, Toribio Jerez y Enrique Echandi; el italiano Aleardo Villa pintó en su país, la alegoría sobre la producción del café y del banano que adorna el Teatro Nacional desde su inauguración en 1897. En el siglo XX figuran temas históricos en obras de Lilly Artavia y de Carlos Aguilar Durán. Destaca en nuestros días la obra de Manuel Carranza Vargas quien dio al género de la pintura histórica un impulso novedoso en la plástica costarricense, al aportar en sus obras al óleo, imágenes estéticas de exquisita belleza y calidad técnica depurada.
