Control of the Chagas disease vector, Triatoma infestans(Klug) (Hemiptera: Reduviidae) with synthetic pesticides in Bolivia has become increasingly inefficient due to the development of resistance in the insects. In the Chaco region of Bolivia, guaraní populations have approached the problem by fumigating their houses with the smoke of native plants. Through interviews and field work with local guides, the main plant used by the guaraníes was collected and later identified as Capsicum baccatumL. var. baccatum(Solanaceae). In choice bioassays, filter papers exposed to the smoke of the plant repelled nymphs of T. infestans. Activity remained significant after storing the exposed filter papers for 9 days. Chemical analysis of smoke and literature data suggested that capsaicinoids present in the smoke were responsible for the repellent effect. The data presented provide a rationale for the use of C. baccatumvar. baccatumto control the Chagas vector bythe guaraní populations.

The species Lippia integrifoliais an aromatic, sub-woody shrub, distributed from Northwest and Central Argentina to Bolivia. It is among the most important native aromatic species. It presents medicinal properties, some of which have been scientifically proven. As an alternative to harvesting, the process of domestication of the species was initiated. The objective of this work was to assess the phenotypic variability based on botanical-taxonomic and morpho-agronomic descriptors and the use of indicators to evaluate its natural situation in the west-center of Argentina. We worked in five wild populations, registering morphological variables, phenology, natural regeneration, herbivory and presence of diseases. L. integrifoliapresents a wide morphological variability, which can be explained with three morphological descriptors. Natural regeneration ́s rate is very low to zero, in four of the sites. The results obtained are of importance to make decisions related to the sustainable use in situ, and to begin a program of domestication of the species.

The effect of multilocational housing on the definition of local residence

Article examines the relationship between residents and public administration from the multilocational dwelling point of view. The data consist of 25 multilocational dwellers’ interviews analyzed by content analysis. The interviewees present themselves as free-time residences, multilocational dwellers and vagabonds between municipalities. Subsequently 12 interviews of multilocational dwellers were analyzed to identify elements of multilocational citizenship. The results show that multilocational residence is produced by questioning the relevance of legal residence and participation rights. As a result, multilocational citizenship is challenging administrative monolocationality leading to a framework of multilocal citizenship.
Luonnonsuojelusta ilmastopolitiikkaan

Artikkelissa tarkastelemme sitä, miten ympäristöpolitiikan käsitteistö ja termistö ovat muuttuneet ja kuinka niiden hallinnasta ja oikeasta käyttötavasta on käyty kamppailua eduskunnan täysistuntokeskusteluissa vuosina 1960–2020. Artikkelin aineistona ovat eduskunnan digitoidut täysistuntopöytäkirjat, joita analysoimme yhdistämällä laskennallisten yhteiskuntatieteiden tekstinlouhinnan ja eksploratiivisen data-analyysin menetelmiä perinteiseen laadulliseen analyysiin. Artikkelissa esitellyt tulokset osoittavat eduskunnassa käydyn ympäristöteemaan liittyvän keskustelun muuttuneen merkittävästi sekä määrällisesti että sisällöllisesti. Keskustelun intensiteetti ja volyymi ovat kasvaneet tasaisesti, mutta samalla aikasarja-analyysi heijastelee politiikan aikapelitiloja, joka näkyy etenkin keskusteluintensiteetin melko voimakkaana vaihteluna. Sisällöllisesti keskeinen muutos näkyy siirtymisenä luontokeskeisestä puhunnasta ilmastonmuutosvetoiseen retoriikkaan. Erityisesti 2000-luvulla ilmastonmuutos-johdannaisista käsitteistä on muodostunut yläkäsitteitä, mikä nähdäksemme ilmentää ilmastonmuutos- vetoisen retoriikan valtavirtaistumisen heijastumista parlamenttipuheeseen: ilmastonmuutoskeskustelu on nykyisin metakeskustelu, jonka alla keskustellaan niin ympäristönsuojelusta, luonnon monimuotoisuuden säilyttämisestä kuin konkreettisista toimista maapallon lämpenemisen hillitsemiseksi.

Määräysvalta vai mahdollisuus?

Published: November 2021

Vallan tutkijat ovat kiistelleet perinteisesti siitä, miten määritellä valta, jotta sen pätevä tutkiminen tulisi mahdolliseksi. Tässä artikkelissa kysytään, miten itse politiikan toimijat – tässä veteraanikansanedustajat haastatteluissaan – puhuvat ’vallasta’, eli millainen poliittisen toiminnan väline ’valta’ on. Kiinnostuksen kohteena on, ymmärtävätkö veteraaniedustajat vallan yksilölle kuuluvana määräysvaltana, yhteistyössä syntyvänä vaikutuksena vai kenties pelitilan luomisena. Keskeinen tulos on vallan monimerkityksellisyys, se on yhtä hyvin vastustamisen väline kuin oman toiminnan merkittävyyden arvioinnin väline. Artikkeli yhdistää käsitehistorian ja digitaalisen tiedonlouhinnan menetelmiä kooltaan laajan aineistokokoelman laadullisessa analyysissä.
Whiteness Owns it, Blackness Defines it
Authors: Swain Amy , Baker Timberly L.
Published: November 2021

Any examination of schools and schooling in the rural Southern Black Belt must interrogate the enduring logic of plantation politics and examine rural equity work through a racialized lens. We defined rural and identify a rural reality for life in the Black Belt South. Critical Race Theory (CRT) and antiblackness are offered as potential race-conscious theoretical frameworks to a plantation rurality, and we propose an alternative vision of rural education scholarship in the Southern Black Belt that invites space for anticolonial liberation.
Why Hillbillies Matter in Social Studies
Authors: Colley Lauren M.
Published: November 2021

In 2016, J. D. Vance, a previously unknown author, surprisingly hit the bestseller’s list with his memoir, Hillbilly Elegy: A Memoir of a Family and Culture in Crisis. However, historically scholars have pushed back against the stereotypes that Vance portrays and have argued for a narrative that embraces the diversity of the Appalachian region. Using content analysis, this research study investigated the frequency and context of key terms related to Appalachia across the K-12 social studies standards of states labeled as being part of the region by the Appalachian Regional Commission (ARC). Results illustrate the lack of inclusion of these terms and that, when included, they do not represent the rich history or culture of the region. These results suggest that researchers, teacher educators, and teachers should consider the ways in which standards define curriculum on topics such as Appalachia and how these definitions interact with the powerful narratives being portrayed within our mainstream democracy. Guidance and suggestions for disrupting Appalachian stereotypes within social studies education are provided.
“I feel the Responsibility”
Authors: Marichal Nidza V.
Published: November 2021

Rural schools in the United States are facing an increase in the number of Emergent Bilinguals (EBs). Teachers in rural communities must facilitate learning for EB students whose linguistic and cultural backgrounds differ from the mainstream. However, rural teachers are less prepared to address EBs’ educational needs, and little is known about the actual teacher knowledge (TK) required to provide effective EB instruction in secondary rural settings. Grounded in teacher knowledge and place-based education frameworks, this qualitative study examined what teachers say they know related to the teaching and learning of EBs in a rural secondary school community. The study addressed two main questions: (1) What personal and professional knowledges do secondary teachers reveal about teaching EBs in rural settings? and (2) What place-based knowledges do secondary teachers reveal about their work with EBs? Primary data from four secondary teachers teaching EBs in a rural school in the southeastern United States consisted of video-recorded interviews and photo elicitation that illuminated teachers’ told narratives of their personal, professional, and place-based experiences via stories. Thematic data analysis followed an iterative approach. Findings from this study demonstrated that the teachers’ personal and place-based knowledges emerged as the most prominent influences in their work. Teachers’ bilingualism, hispanidad, and faith were leveraged to build relationships with their rural secondary EBs. Thus, relationship-building was central to teachers’ knowledge-base of working with EBs. A four-dimensional teacher knowledge model is proposed. Findings may inform teacher education programs and extend the research base on rural secondary EB education

The freedom of choice by motorists of their route, parking places, the duration of rest, as well as the choice of the type of rest in a complex with the natural resource potential of the Crimean Peninsula determine the advantages of campsites over other accommodation facilities. Crimea has a rich and diverse resource potential of recreation and tourism, which determines the popularity of auto tourism. However, the richness of the natural environment is negatively offset by the low aesthetic level of the territories of car camps themselves, where no work on landscaping and landscaping of places of short-term stay of motorists is often assumed. The variety of climatic zones of the Crimean Peninsula implies an individual approach to the landscaping of parking lots and careful selection of plants that can grow in these conditions with minimal care. During the reconnaissance survey on the territories of objects currently used as car camps on the coast of the Crimean Peninsula, an assessment of landscape features, the degree of landscaping, and compliance with GOST R 58187-2018 "Tourist services" was carried out. Camping sites". In the course of the study, the complete or partial absence of landscaping in the territories of car camps and non-compliance with the requirements of GOST (to varying degrees) was established. The assortment for landscaping of car camps on each of the coasts has been selected, taking into account the main limiting factors.

Healthcare workers (HCWs) are known to be at a high risk of being exposed to the SARS-CoV-2, or the COVID-19 virus because they are required to interact with their patients at a distance of less than two meters, for more than ten minutes at a time. Due to limited resources, most HCWs are inadequately protected. This study describes the development and the performance of an affordable full-body isolation pod (isopod). The isopod structure consists of composite side panels and aluminum poles and strips. A clear tarpaulin sheet is used to seal its structure. Two identical a high-efficiency particulate air (HEPA) filters are used to filter the air that goes through the isopod while the pressure inside it is maintained within the range described by the Airborne Infection Isolation (AII) room of the United Stated of America Centers for Disease Control and Prevention (CDC). This isopod could be the solution for hospitals in developing countries to enhance the protection among HCWs from the deadly virus since it is attainable and satisfies the CDC requirements.

BACKGROUND: Bartholin’s abscess is an infection of the Bartholin gland that often occurs in women of childbearing age. The prevalence of Bartholin’s abscess is 2% in the female population worldwide. Patients often complain dyspareunia with a high recurrence rate. Bacterial Vaginosis (BV) is a syndrome of changes in the vaginal ecosystem that occurs spontaneously in sexually active women. BV can contribute to the development of a Bartholin’s gland abscess.
CASE REPORT: A 30-year-old woman came with the chief complaint of a 5 cm × 5 cm erythematous, tender, and mobile mass on the right side of the labia majora. In addition, the patient also experienced recurrent vaginal discharge. The patient was diagnosed with Bartholin’s abscess with BV coinfection that was successfully treated with a modified word catheter and combination of antibiotics that showed no recurrence.
CONCLUSION: Combination of modified word catheter and antibiotics can be a simple yet effective way in treating Bartholin’s abscess.
Le Parlement dans la crise sanitaire

Published: November 2021

Dans l’opinion publique, l’image du Parlement reste celle d’une assemblée trop dépendante de la volonté présidentielle, en dépit des réformes qui visaient à renforcer son rôle propre. Paradoxalement, l’entrée à l’Assemblée nationale de personnes issues de la société civile a contribué à affaiblir sa position. En outre, la crise sanitaire a conduit à légiférer par ordonnances et à réduire le contrôle sur le gouvernement. Il convient de redéfinir les rapports entre l’exécutif et le Parlement.

Pediatric Craniospinal Irradiation – The implementation and Use of Normal Tissue Complication Probability in Comparing Photon versus Proton Planning
Authors: Balasubramanian S. , Shobana M. K.
Published: November 2021

Purpose:

The preferred radiotherapy treatment for medulloblastoma is craniospinal irradiation (CSI). With the aim of developing the potential to reduce normal tissue dose and associated post-treatment complications with photon and proton radiotherapy techniques for CSI. This report aims to carefully compare and rank treatment planning and dosimetric outcomes for pediatric medulloblastoma patients using normal tissue complication probability (NTCP) formalism between photon (three-dimensional conformal radiotherapy, intensity-modulated radiotherapy [IMRT], volumetric-modulated arc therapy [VMAT], and HT) and proton CSI.

Methods and Materials:

The treatment data of eight pediatric patients who typically received CSI treatment were used in this study. The patients were 7 years of age on average, with ages ranging from 3 to 11 years. A prescription dose of 3600 cGy was delivered in 20 fractions by the established planning methods. The Niemierko's and Lyman–Kutcher–Burman models were followed to carefully estimate NTCP and compare different treatment plans.

Results:

The NTCP of VMAT plans in upper and middle thoracic volumes was relatively high compared to helical tomotherapy (HT) and pencil beam scanning (PBS) (all P < 0.05). PBS rather than IMRT and VMAT in the middle thoracic region (P < 0.06) could significantly reduce the NTCP of the heart. PBS significantly reduced NTCP of the lungs and liver (all P < 0.05).

Conclusion:

The NTCP and tumor control probability (TCP) model-based plan ranking along with dosimetric indices will help the clinical practitioner or medical physicists to choose the best treatment plan for each patient based on their anatomical or clinical challenges.
Diagnostic Utility and Accuracy of Scrape Cytology in Evaluation of Neoplastic Lesions
Authors: Sharma Tanya , Singhal Sheetal , Kapoor Neelkamal
Published: November 2021

Background:

Frozen section, intraoperative fine needle aspiration cytology (FNAC) and imprint cytology have been used traditionally by the surgical pathology laboratories for rapid intraoperative diagnosis of tumors. Scrape cytology is a modification of imprint cytology that involves lightly scraping or brushing cells from freshly cut surface of the surgically removed tumor specimens. The present study was carried out to evaluate the utility of scrape cytology in diagnostic evaluation of tumors.

Material and Methods:

A prospective study was carried out at a tertiary care teaching hospital in Central India. A total of 50 consecutively received specimens in the Department of Pathology and Laboratory Medicine with clinical or radiological suspicion of neoplasia were included in the study. Scrape smears were prepared from freshly cut surface of tumor specimens received unfixed or in 10% formalin.

Results:

Overall, the scrape cytology diagnosis was concordant with final histopathological diagnosis in 48 out of 50 cases with a diagnostic accuracy of 96%. The sensitivity was 90.9% (CI-58.72% to 99.77%) and specificity was 97.4%(CI-86.52% to 99.94%). Positive predictive value and negative predictive value were 90.91% and 97.44%, respectively.

Conclusion:

Scrape cytology is a cost-effective and reasonably accurate cytodiagnostic technique for rapid tumor diagnosis. Scrape cytology can be a useful supplementary tool to frozen section, and may be applied for rapid diagnosis where frozen section technique is not available. The material and knowledge obtained from scrape cytology of routinely received histopathological specimens can be utilized as a teaching material and may help unveil diagnostic cytopathological features of infrequent cytologically encountered lesions.
The Effect of the Extent of Neuroendocrine Differentiation on Cytopathological Findings in Primary Neuroendocrine Neoplasms of the Breast
Authors: Guzelbey Burcu , Hacihasanoglu Ezgi , Talu Canan Kelten , Cakir Yasemin , Nazli Mehmet A.
Published: November 2021

Objective:

This study aimed to describe the cytological features of neuroendocrine breast tumors and to show the effect of the extent of neuroendocrine differentiation on cytological features.

Methods:

Breast tumor excision materials showing immunostaining with neuroendocrine markers (Synaptophysin or Chromogranin A) were determined and divided into two groups: cases with focal (10%–50% of tumor cells) staining and cases with diffuse (>50% of tumor cells) staining. A group of cases without neuroendocrine features/staining was used as control group. Fine needle aspiration biopsy specimens of the tumor mass or metastatic lymph nodes were examined and compared.

Results:

Twenty cases with neuroendocrine differentiation were included. Eleven cases were in the diffuse group, nine cases were in the focal group. Clean background, high cellularity, loosely cohesive cell groups with monotonous appearance, and naked nuclei were more common in the diffuse group. On the contrary, tight cohesive cell groups, the proportion of large cells, nuclear pleomorphism, and nucleolar prominence were higher in the group with focal staining. Plasmocytoid appearance, isolated cell groups, and binucleation were in similar distribution in both groups. Although round-oval nuclei were dominant in both groups, round nuclei were observed to be slightly more in the diffuse group. Only two cases in diffuse group showed cytoplasmic granularity and one case in focal group showed necrosis and mitosis. In the control group, tight cohesive groups, large cell size, pleomorphism, prominent nucleoli, and coarse chromatin were more commonly encountered.

Conclusions:

Clean background, hypercellularity, loss of cohesion, naked nuclei, monotonous cells with round nucleus, and granular cytoplasm were more prominent in cases showing diffuse staining with neuroendocrine markers. Suspecting neuroendocrine differentiation in tumors that show focal staining with neuroendocrine markers can be challenging in cytological preparations.
Image Enhancement Using Weighted Bi-Histogram Equalization
Authors: Trongtirakul Thaweesak , Phanthuna Nattapong
Published: November 2021

Image enhancement is one of using in various digital signal processing areas. Advances in microcontrollers, microcomputers and computers have developed traditional algorithms in order to improve the quality of the resulting image and have implied many avenues to the design of new innovations using various techniques. This paper proposes contrast enhancement using weighted bi-histogram equalization based on distributed area ratio. Moreover, this technique must use a weighted factor which is calculated by the ratio of the histogram distribution. Likewise, an original image will be equalized by the modification of the probability density function of the gray levels. As result of the experiment, the contrast of resulting image is improved for implement and human perception – as well as also reduces the absolute mean brightness error (AMBE) than the traditional technique of image enhancement.

The Effects of Temperature and Median Age on Infection Rates of Human-To-Human Transmission of SARS-Cov-2 Virus: Preliminary Findings from a Global Study
Authors: Manickum Thavrin
Published: November 2021

Aims: A preliminary epidemiological study, for COVID-19, for the period January to 31 March 2020, was undertaken for the six major global regions, covering 173 infected countries. Factors that were considered to affect the human-to-human transmission of the SARS-CoV-2 virus: the effect of average monthly country temperature and median age, were investigated.

Methods: Documented case infections were accessed from the WHO website . Temperature, median age, COVID-19 testing data were obtained from relevant sites. Standard statistical data analysis was used to investigate any relationships.

Results: The optimum temperature range for viral infection with SARS-CoV-2 appears to be ± -2,71°C up to 10,50˚C based on about 91% of the total infections occurring at this range. Transmission does appear to occur at a fairly wide temperature range of ± -26˚C up to +33°C. Relatively more cases seem to occur in human subjects at median age of 40,1 ± 5,0 years (56,6%), as noted for Europe, compared to younger subjects of age 20,1 ± 4,3 (0,5%), for Africa.

Conclusions: The virus appears to be fairly stable, and of varying transmission, at extreme conditions of low and high temperature. There may be a seasonal behavior regarding its occurrence in line with a recent finding.

This research aims to explore the effects of social media usage on parents and children interpersonal relationships. Relationships among parents and children are an essential factor in having excellent bonding of family. The total numbers of respondents were 384, who were selected according to Morgan and Krejcie’sformula. Islamabad was the city where the survey was conducted. Probability sampling was used for this study. The study was based on the theory of Time displacement by Robert Putnam (1970). He argued that when we give more time to our virtual world, our time to our real-world will be less. Two hundred children and 184 parents were the respondents of this study. Results showed that most of the users are heavy users; they use social media more than 4 hours on a daily basis. The outcome revealed that Facebook is much admired social media site among users. According to results, 65% of respondents elaborated that social media unite families, and the rest of 35% said that they are against this statement. Furthermore, 73% of the total population responded that social media decreased face-to-face interaction between parents and children. On the other hand, 14% were neutral, and 11% were against this statement. According to results of hypothesis it has been found that both parents and children support positive aspects of social media usage. This study also finds out that heavy social media usage causes many troubles like sleeplessness, interest in the virtual world, and face-to-face interaction between children and parents. This study recommends the less usage of the virtual world and social sites to make strong relations in real life.

Published: November 2021

Abstrak: Kemunculan inovasi dalam dunia keuangan digital beberapa tahun terakhir ini mendapat perhatian dari berbagai pihak yang biasa dikenal dengan teknologi finansial. Inovasi ini berupa teknologi penggalangan dana (crowdfunding) dan teknologi terdesentralisasi berupa blockchain. Kedua inovasi ini tidak hanya dapat digunakan untuk tujuan komersial, tetapi juga untuk kepentingan sosial, termasuk wakaf. Potensi wakaf uang di Indonesia sangat besar. Namun demikian, realisasinya masih relatif rendah. Penelitian ini bertujuan untuk menganalisis sekilas wakaf blockchain di Indonesia yang dapat mengoptimalkan realisasi pengembangan wakaf di Indonesia. Metode penelitian kualitatif melalui studi literatur. Hasil penelitian menunjukkan bahwa Indonesia sangat mungkin menerapkan wakaf blockchain karena jumlah penduduk Muslim yang mencapai lebih dari 80%, konsep fikih wakaf yang fleksibel dan munculnya industri halal. Tantangan terbesar yang dihadapi adalah terkait dengan literasi wakaf untuk meningkatkan kesadaran masyarakat. Penelitian tentang niat yang dirasakan untuk menggunakan wakaf blockchain melalui kuesioner dan wawancara mendalam dengan para pemangku kebijakan penting untuk penelitian di masa depan.

Virtual Indication of the Torque for a Marine Gas Turbine
Authors: Niculescu Filip , Vasile Mirela Letitia , Balan George , Săvescu Adrian , Nicolae Roxana
Published: November 2021

Gas turbines are used in marine applications where high propulsion power is required compared to engine size and mass. In some cases, the torque and engine power developed cannot be measured with a special transducer implemented in applications or if there are indications, they need to be compared with the calculated torque indication. For this purpose, we developed in the engine control software application a mathematical model for calculating and displaying the torque and power developed by the engine. Through comparisons in the tests with the engine on the test bench, this mathematical model was refined. At this time the comparative sampled data can be used as a virtual indication of torque in cases where this is necessary.
