Authors: Fan Long-Fei , Alvarenga Renato Lúcio Mendes , Gibertoni Tatiana Baptista , Wu Fang , Dai Yu-Cheng
Published: August 2021

Samples of species close to Tremella fibulifera from China and Brazil are studied, and T. fibulifera is confirmed as a species complex including nine species. Five known species (T. cheejenii, T. fibulifera s.s., T. “neofibulifera”, T. lloydiae-candidae and T. olens) and four new species (T. australe, T. guangxiensis, T. latispora and T. subfibulifera) in the complex are recognized based on morphological characteristics, molecular evidence, and geographic distribution. Sequences of eight species of the complex were included in the phylogenetic analyses because T. olens lacks molecular data. The phylogenetic analyses were performed by a combined sequence dataset of the internal transcribed spacer (ITS) and the partial nuclear large subunit rDNA (nLSU), and a combined sequence dataset of the ITS, partial nLSU, the small subunit mitochondrial rRNA gene (mtSSU), the translation elongation factor 1-α (TEF1), the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2). The eight species formed eight independent lineages with robust support in phylogenies based on both datasets. Illustrated description of the six species including Tremella fibulifera s.s., T. “neofibulifera” and four new species, and discussions with their related species, are provided. A table of the comparison of the important characteristics of nine species in the T. fibulifera complex and a key to the whitish species in Tremella s.s. are provided.

Les conférences publiques des facultés catholiques de Lyon : l’enseignement d’un droit chrétien, instrument d’une propagande de défense de l’Église
Authors: Biscay Myriam
Published: August 2021

Dans un contexte de vive concurrence avec la faculté d’État, la faculté catholique de Lyon ambitionne, dès son installation en 1875, de présenter un établissement des plus attractifs. En ce sens s’inscrit, concomitamment à l’instauration d’autres facultés catholiques, la mise en place de différents types de conférences. Parmi celles-ci apparaissent rapidement (entre 1878 et 1880) les conférences du vendredi soir destinées non pas aux étudiants des facultés catholiques mais plus largement à des auditeurs libres. Ces conférences semblent s’inscrire dans le champ de l’éducation populaire et illustrent ainsi une modalité spécifique de l’éducation populaire au xix e  siècle : défendre la foi et raviver les convictions chrétiennes. Les conférences dispensées entre 1880 et 1899 visent ainsi à promouvoir une vision chrétienne du droit et traduisent plus globalement l’attitude de l’Église cherchant à renforcer les effectifs des établissements d’enseignement libre.

Afin de mieux percevoir la relation entre performance et ressources intangibles, nous proposons une étude de cas mettant en évidence l’interdépendance entre le système de management de la performance immatérielle (SMPI) et l’influence de facteurs contextuels tels que l’organisation et l’environnement externe.
Piloter la performance globale dans les organisations publiques. Une analyse par le prisme des points de vue
Authors: Khenniche Samia , Henriot Julien
Published: August 2021

Le concept de performance globale est questionné du fait notamment des difficultés de son pilotage. C’est également le constat que nous faisons dans cet article qui s’appuie sur une recherche-intervention conduite au sein d’une collectivité territoriale. Si, par nature, cette organisation poursuit l’ambition de générer une performance globale, elle ne parvient pour autant pas à concrétiser tout à fait cette ambition. Nous mettons en évidence que la notion de performance est trop complexe et trop dynamique pour être saisie dans sa globalité et qu’elle peut être appréhendée que sous la forme de points de vue, nombreux et variés.
L’international en question ? Colonies, économie et commerce international chez Hobbes et Bentham
Authors: Bourcier Benjamin , Jakonen Mikko
Published: August 2021

Souvent délaissée, la pensée politique de l’international chez Hobbes et Bentham recèle plus de points communs qu’on ne pourrait le penser. Pour reconstruire philosophiquement cette pensée, en s’attachant plus spécifiquement au rapport entre économie et politique, on explique d’abord leur commune opposition aux colonies et aux politiques étrangères bellicistes. On montre ensuite comment ils comprennent le commerce international, l’économie et le marché en relation avec l’État, et enfin qu’on ne saurait constituer une théorie politique internationale assurant la sécurité, la paix et la prospérité qui soit autonome et séparée de la théorie de l’État.
Epidemiology of Human Trafficking
Authors: Moukaddam Nidal , Torres Melissa , Vujanovic Anka A. , Saunders John , Le Hai , Shah Asim A.
Published: August 2021

Human trafficking (HT) is a growing public and social health issue internationally. HT is a violation of human rights that needs to be fought vigorously by legal policy, law enforcement, and public health policy. People who are trafficked include men, women, and children of diverse cultural and socioeconomic backgrounds and nationalities. Victims of HT are subject to a high prevalence of violence and mental distress and suffer multiple short-and long-term adverse medical and psychological issues resulting from being held captive, working/living in poor conditions, and having limited/no access to health care. Risks for psychiatric disorders among victims of HT can arise from multiple factors: being isolated and cut off from the outside world, physical and mental abuse perpetrated by traffickers, increased likelihood of substance use and misuse, unsafe working conditions, and lack of social support. In this article, we present the basic epidemiology of HT and its mental and physical correlates and discuss directions for future investigations.

Use of a Structured Framework with Novel Outcome Measures to Describe a Consultation-Liaison Psychiatry Service and its Effectiveness
Authors: Hui Andrew
Published: August 2021

This article describes a new consultation-liaison psychiatry (CLP) service at a subacute hospital in Melbourne, Australia, using a structured framework and novel outcome measures. It also describes the psychiatric needs of the rehabilitation and geriatric evaluation and management (GEM) units. The “structure-process-outcomes” framework was used to anchor objective measures of CLP effectiveness. Relevant information was collected on all admissions and CLP referrals between February and July 2019. Planned and post hoc statistical tests were performed to determine significant associations. Results showed that 22.3% of patients in the rehabilitation unit and 44.2% in GEM unit had active psychiatric disorders (APD); this cohort had significantly greater length of stay (LOS) and less funding per day of admission. Geriatricians refer a significantly lower proportion of those with APD than rehabilitation physicians, likely due to shared clinical expertise in managing neurocognitive disorders. Those referred have significantly greater psychiatric comorbidity and LOS than those not referred. Despite this, CLP interventions was associated with a significantly reduced number of readmissions in the 180 days post-initial discharge. Describing a CLP service using a structured framework with objective outcome measures allows for deeper and more nuanced evaluation of service effectiveness. A substantial proportion of patients at rehabilitation and GEM units have APD.

Why Teach Coding to Early Elementary Learners
Authors: Mihm Claudia M.
Published: August 2021

As coding and computer science become established domains in K-2 education, researchers and educators understand that children are learning more than skills when they learn to code – they are learning a new way of thinking and organizing thought. While these new skills are beneficial to future programming tasks, they also support the development of other crucial skills in early childhood education. This chapter explores the ways that coding supports computational thinking in young children and connects the core concepts of computational thinking to the broader K-2 context.
Rhyme and Reason
Authors: Govind Madhu , Hassenfeld Ziva Reimer , de Ruiter Laura
Published: August 2021

The chapter begins with an exploration of computational thinking (CT) and its relationship to computational literacy, followed by a summary of theoretical and empirical work that aims to elucidate the connections among coding, CT, and literacy. The authors argue that these connections thus far have been predominantly one of support (i.e., unidirectional) and motivated by technological and policy advances, as opposed to considering the connections as mutually reinforcing and developmentally coaligned. The authors discuss the coding as another language (CAL) pedagogical approach, a pedagogy that presents learning to program as akin to learning how to use a new language for communicative and expressive functions, emphasizing the bidirectional connections between the two domains. Finally, the authors detail various curricula that use the CAL approach and discuss the implications of CAL for teaching and learning in early childhood.

Published: August 2021

Over the past decade, there has been a growing interest in learning analytics for research in education and psychology. It has been shown to support education by predicting learning performances such as school completion and test scores of students in late elementary and above. In this chapter, the authors discuss the potential of learning analytics as a computational thinking assessment in early childhood education. They first introduce learning analytics by discussing its various applications and the benefits and limitations that it offers to the educational field. They then provide examples of how learning analytics can deepen our understanding of computational thinking through observing young children's engagement with ScratchJr: a tablet coding app designed for K-2 students. Finally, they close this chapter with future directions for using learning analytics to support computer science education.

Published: August 2021

This investigation aims to use corn cover as natural fibers in concrete mixes to improve some mechanical properties like compressive strength, tensile strength, and flexural strength. using any type of fiber in concrete, in general, can improve the tensile and flexural strength of concrete. Concrete is weak in tension, so using fibers such as natural fibers like trunk fibers or industrial fibers such as steel fibers can improve tensile, the flexural strength of concrete and that may be decreasing the use of steel reinforcement in concrete, and also fibers can improve toughness and ductility of concrete because of its work inside the concrete that can reduce the propagation of cracks under loading. This study shows slight improvement on compressive strength by using fibers, but high increments in flexural strength, the optimum ratio of corn cover fibers was 2.5% by weight of cement which gives the highest values in compressive strength and flexural strength. compressive strength increased from (31.2 to 35.9) MPa (about 15% increment), increment for flexural strength was 70.6% for the optimum fibers content and the failure by using corn fibers was a ductile failure compared with plain concrete that gives sudden failure under flexure load, also tensile strength increased by using fibers, more fibers content beyond or more than 2.5% give lower values for the mechanical properties.

Authors: Aziz Fauziah , Arshad Mohd Fadzil , Mansor Hazrina
Published: August 2021

Biaxial Interlocking Block (BIB) is a new interlocking block system introduced in this research work. BIB was designed and expected to have the capacity to resist the biaxial load. In this research, the production of BIB was introduced, and the properties of BIB as the individual and walling unit was identified. The features of BIB in terms of density, compressive strength and MOE was identified. To define the impact BIB to the masonry wall capacity, nine walls panel and nine prisms including Solid Block (SB) and cement sand brick (CSB) have been constructed and tested under concentric compressive load. From the data obtained, the BIB walling system was calculated and identified. All the properties values of BIB masonry obtained compared with SB and CSB masonry values. The relationship of masonry properties by different types of masonry unit was also identified and discuss. From all the data and analysis carried out, it is found that the features of masonry unit have influenced the walling properties of the constructed wall. The higher compressive strength of masonry unit will enhance the capacity of the masonry walls. From this research, it is also found that BIB is having excellent properties as a walling unit as compare to SB and CSB wall. A linear relationship between the compressive strength of the samples regardless of the changing in masonry unit compressive strength has been found appropriate with the same slenderness ratio. This work offers valuable data of BIB to the masonry walls properties under compressive load.

Published: August 2021

The tribological properties of roller and guide tribo-pair are important for the design of deployable structure for space-borne perimeter truss antenna. In this study, carbon fiber epoxy resin composites are used as the guide material; while polyimide and GCr15 steel are used as the roller material. Then, friction coefficient of polyimide ball and GCr15 steel ball against carbon fiber epoxy resin composites disk were compared and investigated on the high-temperature, ball-on-disk tribometer under different operating conditions, respectively. The wear morphology of disk was measured by laser scanning confocal microscope. The results show that the friction coefficient of the polyimide ball against carbon fiber epoxy resin composites tribo-pair has better tribological properties. Meanwhile, the friction coefficients of this pair are mainly depend on abrasive wear under low pressure and velocity conditions while the adhesive wear has dominated influence on the friction coefficient for high pressure and velocity conditions. Besides, the tribological properties of carbon fiber epoxy resin composites are mainly affected by ploughing of surface roughness at low temperature, while by surface debonding at high temperature.

Authors: El Sayed Ziad , Abd-Alrazzaq Mohamed , El-Galy Islam
Published: August 2021

Open-cell Al-Si foam samples were produced using infiltration casting technique. The metal infiltration process was performed in a specially designed and built setup consisting of a vertical chamber resistance furnace, a pressurization chamber connected to an Argon gas cylinder through a control manifold. To control the relative density of the produced foams, non-compacted and compacted preforms (5 MPa) were prepared from 2 or 4 mm NaCl particles. The compaction was performed using a hydraulic press in the same infiltration chamber. Argon pressure of 3 bars was applied to infiltrate the preforms with the aluminum alloy after melting at 750 °C. The produced aluminum foam specimens show no lack of filling, a high degree of preform replication, and good homogeneity of pore sizes. The preliminary physical and mechanical characterization tests, including relative density, plateau stress, densification strain, and elastic modulus of the foam, are comparable to the values reported in previous investigations, in which more complicated, time-consuming, higher energy, and costly techniques were used. Further investigations on wider ranges of particle sizes, compaction, and infiltration pressures are currently in progress.

Published: August 2021

Background

Parkinson's disease (PD), which occurs in 1% of the population, is the second most common neurodegenerative disorder. Despite the broad spectrum of PD manifestations and high disease prevalence, there are insufficient data on medicine utilization and prescription strategies. The purpose of the current study was to analyze published data concerning treatment approaches and to compare them with Bulgarian therapeutic practice.

Design and methods

We conducted a systematic review of the PubMed and Google Scholar databases, and we calculated medicine utilization in Bulgaria during 2018 and 2019 using the WHO methodology.

Results

The literature search identified a total of 311 publications, but only 12 met the inclusion criteria. Eleven studies pointed out that levodopa-containing medicine are the most frequently used, followed by dopamine agonists. The highest rate was found for levodopa-containing products and decarboxylase inhibitor (1.06 and 1.33 DDD/1000 inh/day), followed by anticholinergic Biperiden (0.494 and 0.455 DDD/1000 inh/day) during 2018 and 2019 in Bulgaria.

Conclusion

Overall, the treatment approaches used in the last decade comply with guideline recommendations, despite variations in levodopa and dopamine agonist utilization. Even though new medicines have been approved for PD management, levodopa- containing products are still most often prescribed and used worldwide.

Published: August 2021

Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome that accounts for more than half of all heart failure patients. Identification, early diagnosis and management of patients are still complex, and no targeted treatment is available, since all tested drugs were not able to lower hard clinical outcomes. A multi-hormonal deficiency syndrome has been described in HFpEF patients suggesting that different hormones may represent new biomarkers of the disease, but their clinical utility is still debated. The natriuretic peptides are the cornerstone biomarker in heart failure, predicting cardiovascular death and heart failure hospitalization. Testosterone and DHEA-S deficiencies have been reported in HFpEF and associated with right ventricular impairment and diastolic dysfunction. IGFBP-1/IGF-1 axis correlates with echocardiographic parameters of HFpEF patients and with several prognostic biomarkers including NT-proBNP and C reactive protein. Low triiodothyronine syndrome is frequently found in HFpEF and thyroid hormones should represent a potential biomarker of risk stratification and prognosis.

Published: August 2021

Psychological trauma occurs when a person suffers from serious threat or loss to his/her life. Childhood psychological trauma can be of various forms such as physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect. Such adverse childhood experiences, if not effectively dealt or resolved, may lead to the development of drug dependence including alcohol dependence syndrome (ADS) in adult life. In many cases, development of ADS is preceded by the occurrence of childhood psychological trauma(s). Such a person with a history of childhood psychological traumas may consume alcohol to cope with his/her trauma-related distress. Alexithymia is a state characterized by a triad of difficulty in identifying one's own feelings, difficulty in differentiating between physical sensations and emotional arousal, and difficulty in explaining one's own feelings to others. Alexithymia has a role in the development of drug dependence including ADS. The number of childhood psychological trauma among persons with ADS was associated with alexithymia in adulthood. Childhood psychological traumas, mainly emotional abuse, might act as a predisposing factor for the development of alexithymia in persons suffering from ADS. This case series presented clinical picture of two individuals with ADS in which both childhood psychological trauma(s) and alexithymia were assessed by using standard and psychometrically valid psychological tools such as Childhood Trauma Questionnaire and Toronto Alexithymia Scale-20 item, respectively. This case series is unique because the assessment of childhood psychological trauma(s) and alexithymia is neglected area in Indian psychiatric research field and detailed ample of literature is not available at present in which the relationship between childhood psychological traumas, alexithymia, and ADS has been assessed. In the present case series, first individual with ADS had clinically significant alexithymia, severe emotional abuse, severe emotional neglect, moderate physical abuse, and moderate physical neglect, while second individual with ADS had no alexithymia but he had moderate-level emotional neglect and mild levels of emotional abuse, physical abuse, and physical neglect.

Published: August 2021

There are a variety of perspectives on wildlife management and conservation, necessitating interdisciplinary research to develop better management strategies. We answered the call to action provided by Teel et al. (2018) to integrate social sciences into conservation and explored an important but understudied issue: views on the international pet-trade of exotic animals. Some pet owners advocate the pet trade as a means to promote conservation, where removing wild animals from their natural habitat could protect them from degraded environments. To gauge how prevalent this attitude is in a cross-national sample, we conducted an online survey that asked 882 participants worldwide to evaluate the pet trade and its relationship with biological conservation. Overall, our survey results showed regional patterns and indicated that younger respondents were more likely to consider international pet trade as a form of acceptable conservation practice compared to older respondents. Education also played a role in shaping views on the pet-trade and indicated that respondents with higher education degrees were less prone to accept pet trade as a substitute for conservation practices. Our research provides novel insights applicable to education programmes and international conservation efforts while highlighting variation in attitudes even among professionals with formal training in natural sciences and ecology.

Authors: Karia Sagar , Desousa Avinash , Shah Nilesh
Published: August 2021

Background:

Cerebroprotein hydrolysate (cerebrolysin) is a nootropic and neurotrophic drug used widely in the management of various forms of dementia, stroke and head injury. A number of case series and anecdotal case reports on its efficacy exist. This study is a retrospective chart review of 34 patients with dementia treated at a tertiary general hospital psychiatry department that were given oral cerebroprotein as add on to their existing treatment for dementia.

Methodology:

34 patients were administered twice daily oral cerebroprotein 90 mg tablets for 90 consecutive days. The cognitive assessment was done before the first injection and after the last dose using the Adenbrook's Cognitive Examination-Revised (ACER) and the Mini Mental Status Examination (MMSE).

Results:

Changes on cognitive assessment were minimal and no major improvements were seen though isolated areas of improvement were reported by many patients. The scores on the ACER and MMSE remained in the dementia range though improvement in scores were noted. None of the patients experienced any major side effects with the drug.

Conclusions:

Oral cerebroprotein is a useful agent in the management of dementia and must be tried as an add-on to regular dementia treatment. Larger studies in prospective cohorts with further stringent assessments warrant exploration.

Published: August 2021

Background:

There is a need to study age-sensitive psychological management for improving the clinical and overall health outcome for elderly adults. Hence, we intended to evaluate the effects of selection, optimization, and compensation (SOC) model, usually studied in nonmental health settings predominantly, in managing depression and well-being of the elderly in a clinical mental health setting in an Indian context.

Methods:

A pre–postintervention with a 2-month-follow-up approach was adopted. We delivered six sessions over 4–5 months. An independent rater assessed participants using the Beck Depression Inventory-II and World Health Organization's Well-Being Index (WHO-5) at baseline, postintervention, and a 2-month follow-up.

Results:

There was a clinically significant improvement in depression severity and well-being of participants at the postintervention and 2-month follow-up.

Conclusions:

SOC-based intervention has potential therapeutic effects in improving depression severity and well-being of elderly individuals in clinical settings. We recommend the current protocol to be studied in a randomized design study with a larger sample size and a longer follow-up period.

Authors: Grover Sandeep , Chakravarty Rahul , Mehra Aseem , Chakrabarti Subho
Published: August 2021

Aim:

To assess the prevalence of metabolic syndrome (MetS) in elderly patients with depressive disorder.

Methodology:

By using retrospective study design, the treatment records of all the elderly patients (aged ≥60 years) diagnosed with depressive disorders diagnosed as per the International Classification of Diseases, 10th Revision, were reviewed and data of patients for fasting blood glucose levels, lipid profile, and anthropometry (height, weight, waist circumference, and blood pressure [BP]) were extracted. The diagnosis of MetS was made as per the consensus criteria.

Results:

Data of 93 patients were included in the study. The mean age of the study participants was 65.65 (standard deviation [SD]: 5.61) years and the mean number of years of education was 8.33 (SD: 6.65) years. The mean duration of illness was 70.93 (SD: 107.39) months, with the mean duration of the current episode at the time of collection of data as 5.38 (SD: 3.54) months. More than half (57%) of the patients fulfilled the criteria for MetS. Besides more than half of the patients fulfilling the criteria for MetS, about one-tenth (9.7%) fulfilled one criterion, and one-third (32.3%) fulfilled 2 criteria for the MetS. The most common criteria of MetS which was fulfilled included abnormal waist circumference, followed by raised blood pressure, abnormal triglyceride levels, and abnormal high-density lipoprotein. Fasting blood glucose level was the least common abnormality. The presence of MetS was associated with a higher level of education, higher income, and presence of physical comorbidity.

Conclusions:

Considering that more than half of elderly patients with depressive illness also suffer from MetS, it is important to monitor elderly with depression for MetS, to reduce the risk of future cardiovascular morbidity and mortality.

Authors: Mehra Aseem , Rani Seema , Sahoo Swapnajeet , Nehra Ritu , Grover Sandeep
Published: August 2021

Aim:

To compare the level of cognitive functioning among those with and without noncommunicable diseases (NCDs).

Methodology:

Using a cross-sectional study design, 104 patients attending the NCD clinic of a community rural health center and 101 elderly participants attending the hospital as caregivers of patients coming to the same community clinic with different ailments, were assessed on Hindi Mental State Examination (HMSE), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) scale.

Results:

Those with NCD performed poorly on all the domains of HMSE except orientation and registration. When the HMSE score of <25 was used to categorize the sample into those with and without cognitive impairment (CI), it was seen that the prevalence of CI was more among those with NCDs. The significant difference between the two groups persisted, even after controlling for age, gender, the income of the family, number of years of education, type of family, socioeconomic status, mean score of PHQ-9, and mean score of GAD-7.

Conclusion:

NCDs are negatively associated with cognitive functioning even after controlling for age, gender, the income of the family, number of years of education, type of family, socioeconomic status, mean score of PHQ-9, and mean score of GAD-7.
Are donor predonation variables related to the quality of single donor platelets? – A tertiary care center experience
Authors: Chatterjee Priti , Sehgal Shivali , Bhardwaj Swati , Bhushan Reema , Pathak Chintamani , Jain Manjula
Published: August 2021

Introduction:

Platelets are the most common product collected by apheresis. The product obtained is called single donor platelets (SDPs). The quality of the SDP is determined by the platelet yield (that is platelet count of the SDP product), which in turn directly influences the patient recovery.

Materials and Methods:

In the present study, donor demographic and complete blood count parameters were studied and their influence on the yield of the SDP was analyzed. With such an analysis, a better quality product (with a good platelet yield) can be obtained consequently improving clinical outcome. This would allow prolonging intervals between transfusions.

Results:

Parameters such as height, weight, and body mass index did not statistically influence the platelet yield in this study, unlike the results obtained by past studies. The most consistent parameter found to influence the platelet yield was platelet count of the donor. Healthy donors with high platelet counts can yield better platelet yield in SDPs in a shorter time and therefore improve the clinical outcome in patients with thrombocytopenia.

Conclusion:

It is important to consider hematological characteristics of the donors on an individual basis so as to ensure a good quality of the plateletpheresis product.
A review of rare palatal fractures and their management
Authors: Kumar Umesh , Jain Pradeep
Published: August 2021

Objective:

The objective of this study was to diagnose rare palatal fractures and to subcategories them to formulate a definitive treatment plan depending upon the fracture lines.

Materials and Methods:

All patients presenting in triage with palatal fractures were classified after computed tomography scan. Thirteen patients diagnosed with complex and transverse palatal fractures were included in the study. Complex fracture was further subdivided into five groups: (a) comminuted, (b) oblique, (c) S shaped, (d) C shaped, and (e) T shaped. The patients were divided into two groups. In Group A, six patients were managed without palatal vault plating, and in Group B, seven patients were managed with palatal vault plating along with anterior alveolar and anterior maxillary buttress plating.

Results:

Twelve patients presented with complex fracture and one patient presented with transverse fracture. The male-to-female ratio and age range of the study were 5.5:1 and 15–55 years, respectively. Le Fort I and II fracture was present in five patients, isolated Le Fort II fracture in four patients, Le Fort I was present in two, and Le Fort I, II and III fractures was present in two patients.

Conclusion:

Complex palatal fractures can be subcategorized which simplifies the management and documentation of the fracture. Palatal vault plating should be attempted in cases where there are two large fracture segments to achieve the better stability of fracture and reduce the duration of maxillomandibular fixation in postoperative period.

Tubular adenoma is a rare benign neoplasm of the breast. It is commonly seen in premenopausal women and has no association with an increased risk of breast cancer. It is difficult to diagnose tubular adenoma clinically, radiologically, and cytologically. Histopathological examination remains the gold standard in diagnosing tubular adenoma.
Narrow equidistribution and counting of closed geodesics on noncompact manifolds
Authors: Schapira Barbara , Tapie Samuel
Published: August 2021

We prove the equidistribution of (weighted) periodic orbits for the geodesic flow on noncompact negatively curved manifolds toward equilibrium states in the narrow topology, i.e. in the dual of bounded continuous functions. We deduce an exact asymptotic counting for periodic orbits (weighted or not), which was previously known only for geometrically finite manifolds.

Comparison of Nutrition Values of Discarded Fish By Bottom Trawl Fishing in the Mersin Bay
Authors: Dağtekin Büket Buşra
Published: August 2021

In the present study, proximate composition and meat yield of discarded fish Tub gurnard (Chelidonichthys lucerna Linnaeus, 1758), brown comber(Serranus hepatus Linnaeus, 1758) and Scaldfish (Arnoglosus laterna Walbaum, 1792) caught in Mersin Bay (Northeastern Mediterranean) by bottom trawlers were investigated. The highest protein values and the lowest total lipid and ash values were recorded during spring in three species (P<0.05). Meat yield was found to be different significantly among spring and autumn samples (P<0.05). Mean meat yield of tub gurnard, brown comber and scaldfish were 50.94%, 53.85% and 64.56%, respectively. Results of study show that although these species are considered to be discarded, they can be considered as food or additive for various living groups due to their high nutritional quality, thus they can contribute significantly to the food requirement and economy of the country. Thus, both the ecological balance in the marine environment will be protected and economic losses will be prevented.

Published: August 2021

This study investigated the bacteria present in natural and cultured fish species from the same aquatic system, and difference of their antibiotic resistance. A total of 129 fish, Georgian shemaya (Alburnus derjugini), black sea salmon (Salmo labrax) and rainbow trout (Oncorhynchus mykiss), were sampled on a monthly basis between the months of October 2016 and September 2017 in Kürtün Dam Lake. A total of 41 bacterial isolates were isolated from the fishes. The bacterial species were identified by molecular methods (PCR) using universal primers for bacteria. Acinetobacter lwoffii, Acinetobacter sp., Aeromonas sobria, and Pseudomonas sp. were isolated from both wild and cultured fish. Yersinia ruckeri was isolated from cultured fish, which showed severe mortality rate and typical symptoms. Various antibiotics including ampicillin (AMP10µg), gentamicin (CN10 µg), oxytetracycline (T30 µg), amoxicillin/clavulanic acid (AMC10µg), enrofloxacin (ENR5µg), trimethoprim/sulfamethoxazol (TMP-SMZ25µg), florfenicol (FFC30µg), sulfamethoxazol (SMZ25µg) and erythromycin (E15µg) were used for determination of the bacterial resistances. The highest resistances were determined against ampicillin (56%), sulfamethoxazol (46.3%) and oxytetracycline (34.1) in all bacterial isolates. While the bacteria isolated from wild fish did not show resistance to enrofloxacin and amoxicillin/clavulanic acid, those from cultured fish did not show resistance to gentamicin and erythromycin.

Nimonic C263 a nickel base super-alloy is generally used in the major components particularly in various structural and hottest sections of the gas turbine engine mainly in the combustor, exhaust sections including blades, discs, liners, and casings, etc. The interpulse gas tungsten constricted welding process is a modified controlled heat input arc welding technique. In this experiment response surface, rotatable central composite experimental design is methodically implemented for the evaluation of the impact of the key factors (i.e. interpulse current, weld current, weld speed and background current) on the tensile strength of butt-welded joints. The welded coupons are tested for tensile tests and obtained a maximum of 1152MPa. The outcome of this experimental examination and thorough optimization will be useful in choosing the most appropriate and suitable welding ranges of the above-mentioned factors for interpulse gas tungsten constricted arc welding of Nimonic superalloy C263 for automotive and aerospace applications.
Experimental Testing of Low Power Consumption and Cost-effective Converter for De-icing System in Aircraft, Wind Turbine and Solar Panel with the Help of Induction Heating
Authors: Ganapathi R. , Harinarayana T.
Published: August 2021

This paper shows a topology about de-icing of aircraft wings and tails with the help of voltage fed high frequency parallel resonant inverter with the induction heating load. Icing of aircraft reduces the lift and trust of the aircraft. The aircraft de-icing system is economically expensive and consumes more power. To overcome the above factor the new proposed model is developed. It is based on the operation of the rectifier used in a circuit and Pulse Width Modulation technique. Bridgeless rectifiers used to convert the AC to boosted DC voltage without the help of choppers and parallel resonant converter proposed to do high frequency conversion help to reduce the losses in power. The characteristics are analysed by the simulation operation and practical results in terms of temperature, time, voltage and current. Analysis is carried out with the help of MATLAB and waveform is obtained. The prototype is built and tested the practical results to reduce the de-icing system. The icing melting point is 0?C and water to steam conversion melting point is achieved with 80C in our proposed converter and also practical tested in a pilot scale model.

Published: August 2021

Accuracy and safety of tank guns are dependent a great degree on the condition of its gun bore. Many parameters affect accuracy and safety and have strong and complex interdependencies. While it is extremely difficult to monitor all these parameters during battle conditions, it is also essential to enhance the accuracy of the gun by measuring and compensating these parameters. Among all, bore wear and bore centreline are predominant factors. The surface characteristics of the bore also are indicative of potential accidents/deterioration, which should be monitored continuously. Hence, condition monitoring of tank gun bore characteristics in near real-time is an impending need with huge potential for enhancing the combat effectiveness of tank formations. This paper analyses various bore parameters affecting accuracy and safety and proposes a comprehensive condition monitoring method that uses vision camera, thermal camera and mechanical profiler. This integrated approach provides enhanced accuracy in measuring surface characteristics of tank bore that has been partially validated.
