Developing high-efficiency purely organic blue organic light-emitting diodes (OLEDs) that meet the stringent industry standards is a major current research challenge. Hyperfluorescent device approaches achieve in large measure the desired high performance by combining the advantages of a high-efficiency thermally activated delayed fluorescence (TADF) assistant dopant with a narrowband deep-blue multi-resonant TADF (MR-TADF) terminal emitter. However, this ap-proach requires suitable spectral overlap to support Förster resonance energy transfer (FRET) between the two. Here we demonstrate colour tuning of a recently reported MR-TADF B,N-heptacene core through control of the boron substituents. While there is little impact on the intrinsic TADF properties - as both singlet and triplet energies decrease in tandem - this approach improves the emission colour coordinate as well as the spectral overlap for blue hyperfluorescence OLEDs (HF OLEDs). Crucially, the red-shifted and more intense absorption allows us to pair this MR-TADF emitter with a high-performance TADF assistant dopant and achieve maximum external quantum efficiency (EQEmax) of 15% at colour coordinates of (0.15, 0.10). The efficiency values recorded for our device at a practical luminance of 100 cd m-2 are among the highest reported for HF TADF OLEDs with CIEy ≤ 0.1.

The Union Carbide(UC) catalyst, one of the first ethylene polymerization (EP) catalysts based on supported organometallic compounds, is based on chromocene dispersed on silica; it is distinct from the corresponding Phillips catalysts, based on supported chromium oxide, because it is responsive to H2 enabling tuning the resulting polymer. Yet, despite 50 years of research, the structure of its active sites has also been controversially discussed and remains elusive. Based on a combination of IR, EPR spectroscopies, labeling experiments, and modeling at the DFT level, we identified monomeric surface-supported Cr(III) hydrides, (≡SiO)Cr(Cp)-H, as the active sites of the UC catalyst. These active sites, with distinct EPR signatures, are exclusively formed at high Cr loadings because their formation requires a combination of congruent factors, namely the presence of grafted as well as adsorbed chromocene together with residual surface OH groups, and involves a C-H bond activation step of the Cp ring. These Cr hydrides readily initiate polymerization, yielding Cr(III) alkyl species that insert ethylene monomers through a Cossee Arlman-type mechanism, as evidenced by labeling and spectroscopic studies. This information inspired the design of a well-defined analog, that was prepared and characterized using SOMC by grafting CpCr(CH(SiMe3)2)2 on partially dehydroxylated silica. The resulting surface Cr sites show similar EPR signatures and produce similar polyethylene as the UC catalyst, further supporting the presence of similar active sites and opening the way to generating new classes of catalysts.

Water is arguably the most important molecule for mankind. It is becoming more critical to secure water supply, which is increasingly difficult. Desalination is an ideal solution – taking abundant seawater and turning it into potable water – however requires energy for distillation and/or membrane-based reverse osmosis (RO) processes even though the technologies were highly optimized. Modern desalination technologies, namely RO membranes, is based on the rejection of ions (mostly sodium and chloride) on the phase boundary is the main mechanism. Meanwhile, the development of supramolecular chemistry showed that selective recognition and sequestration of ions can reduce energy input by taking advantage of pre-organized “host” environments. However, this approach renders difficulties in aqueous media due to high hydration energy of ions. Moreover, a regeneration of the host can be cumbersome due to the high affinity between the host and guest ions, which is prerequisite for the recognition. We found a completely different approach: stimuli mediated ion-exchange for removing chloride ions. This is based on well-known Solvay process where baking soda is produced from brine (NaCl + H2O), CO2 and ammonia. After ion exchange between ammonium bicarbonate and salt, ammonium chloride is produced, which is water soluble. By employing hydrophobic amines, now we can mediate Solvay-like process while removing in situ generated ammonium chloride from brine solutions and real seawater samples up to 1 L scale. This method can be applied in a continuous flow system with amine-decorated resin, producing desalinated water by using only CO2 and acid treatment to decompose produced NaHCO3.
Approach to Shock
Authors: Chan Janet
Published: February 2022

Shock is a life-threatening pathophysiologic state referring to inadequate organ perfusion, which can progress to end-organ dysfunction and eventually, multiple organ failure and death. The diagnosis of shock is clinical, necessitating good understanding of the underlying etiology, pathophysiology, as well as the clinical, biochemical, and hemodynamic manifestations of the various presentations of shock. This article describes an approach to shock, highlighting the important initial actions, pertinent clinical findings, and the four main types of shock, and offers an overview of the inotropes and vasopressors used in the intensive care setting. A case study and additional figures are included to supplement the presented concepts.

Knowledge on the reproductive biology of the endemic clupeids Limnothrissa miodon and Stolothrissa tanganicae, two main target species of the pelagic fisheries of Lake Tanganyika, is constrained by fragmented monitoring activities. Here, we investigate the nursing areas of L. miodon, the timing of reproductive activities of littoral and pelagic L. miodon, and the timing of reproductive activities of pelagic S. tanganicae in the Congolese waters of the northern end of Lake Tanganyika (Bujumbura sub-basin). Nursing areas were determined year-round (2009–2010) based on the presence of clupeid larvae at two sandy and two stony beaches. The gonadosomatic index (GSI) and the proportion of fish having ripe gonads were used to study variation in reproductive indices in space (littoral vs. pelagic zones) during one year (2013–2014), as well as in time (dry vs. rainy season) during three years (2013–2016). Larvae of L. miodon were more frequently encountered on sandy than on stony beaches. Mature L. miodon females were more abundant in the littoral than in the pelagic zone, while the proportion of mature males in both habitats was similar. Irregular, low amplitude peaks could be distinguished in the GSI and proportion of mature males and females, but averages only differed between the dry and the rainy season in males. In contrast, GSI and proportions of mature males and females in S. tanganicae were higher in the dry season than in the rainy season. The reproductive effort of males and females of S. tanganicae and littoral L. miodon, but not pelagic L. miodon, was strongly synchronized. Interestingly, reproductive investment was also synchronised between pelagic male L. miodon, and pelagic S. tanganicae. Our time series strongly supports the view that L. miodon reproduces year-round in the littoral zone, while reproduction in S. tanganicae is seasonal. For fisheries management, we recommend year-round protection of sandy beaches, which are the main breeding grounds for L. miodon.

The aim of this study was to evaluate the amounts of time that selected crossbreeds of Holstein (H), Red-Holstein (R), and Czech Fleckvieh (C) cattle spent chewing, eating, being physically active using a Vitalimetr 5P neck responder during the period around oestrus in all seasons of the year. Oestrus and the days preceding it greatly affected the times of events of increased activity, eating, and rumination. Eating and chewing times were longest for H cows, at 51–74%, and shortest for C cows, at > 88%. The number of events of increased activity was highest (533.4 ± 8.94 events, P < 0.01) for cows R 51–74%. Oestrus in dairy cows was manifested by decreases in the times of chewing and eating and the frequency of events of increased activity. Feeding time decreased by 8.01 min from the second day before oestrus to the day of oestrus. Rumination time also decreased from the second day before oestrus to the day of oestrus. Rumination time on the day of oestrus decreased by an average of 61.80 min but increased the next day by 33.39 min. In contrast, events of increased activity were highest on the day of oestrus (623 ± 7.68 events). Our findings on differences between breeds, lactation order, and months may contribute to the improvement of algorithms for detecting oestrus, thereby improving the economic status of farms.

Exposure to pollutants is considered one of the potential reasons of population declines in bats. In the context of previous studies, we managed to create and keep a wide collection of cell lines from European bat species. Liver cells were chosen for testing, as they represent the preferred model for toxicological studies. Bats are protected, cell lines replacing experimental animals thus represent a unique opportunity to examine effects of pollutants which animals are exposed to in their environments. Moreover, cell incubation temperature variation may simulate physiological states of heterothermic bats. Liver cell lines were cultivated to the required cell number. Exposure to five different concentrations of permethrin (PM) and imidacloprid (IMI) were used to determine cytotoxic effects of these pesticides on Nyctalus noctula-derived liver cells cultivated at 37 °C and 8 °C for 24 h. An assay based on the measurement of activity of lactate dehydrogenase released from damaged cells was used for quantitating cytotoxicity. Cytotoxicity of IMI ranged from 0% to 47% and from 56% to 67% at 37 °C and 8 °C, respectively. Cytotoxicity of PM ranged from 36% to 56% and from 43% to 88% at 37 °C and 8 °C, respectively. Permethrin was tested on the cells at an order of magnitude lower concentrations; even so, higher degree of cytotoxicity was recorded. Imidacloprid was more toxic to bat liver cells at a hibernation temperature than at body temperature of 37 °C.

The monitoring of radiocaesium in the ecosystems of particular areas in the Czech Republic is necessary even decades following the Chernobyl nuclear disaster. We report an evaluation of the radioactive contamination of the meat of wild boars hunted in the Novohradské (Gratzen) Mountains in the period of December 2012 to December 2019. Radionuclide 137Cs is surveyed for food safety as a source of food chain contamination and a possible risk for human health. Overall, 654 samples of game meat from wild boars were analysed for 137Cs activity. The 137Cs legal limit of 600 Bq·kg-1 was exceeded in 238 samples (36.4%) of hunted wild boar meat. Statistical analysis showed that 137Cs activities measured in wild boar muscle in March reached lower values compared to the period from June till November (P < 0.05). Higher values were reported in September (P < 0.05) as well as in August (P < 0.01) compared to December. A signiﬁcant season-based 137Cs level was found (P < 0.000). Higher 137Cs activities in wild boar in the winter season (November to April) are related to decreasing access to a naturally occurring diet with a lower 137Cs content. The keepers of the wild boar in this area were ordered to comply with obligatory emergency veterinary precautions set by the Regional Veterinary Administration to analyse all hunted game meat for radiocaesium. All wild boars with an above-limit 137Cs value had to be excluded from the food chain by hunting ground keepers and disposed of safely.

La situación económica a la que se enfrentan las parroquias rurales del Ecuador es preocupante debido a la escasa formulación de proyectos que contribuyan a crear oportunidades para mejorar las condiciones de vida de la población. En este sentido, el turismo puede constituirse en una alternativa de generación de empleo y crecimiento económico. El presente estudio tiene como objetivo determinar la potencialidad turística de la parroquia Seis de Julio de Cuellaje del cantón Cotacachi, provincia de Imbabura. Para el efecto, se empleó la metodología de jerarquización de atractivos y generación de espacios turísticos del Ministerio de Turismo del Ecuador 2018 y se adaptó la fórmula de evaluación multicriterio, misma que es igual a la división del criterio alcanzado por el atractivo sobre la ponderación estándar de los criterios de valoración. Se analizaron 20 atractivos turísticos, tres corresponden a la jerarquía II y 17 son de jerarquía I. Los criterios: estado de conservación e integración sitio/entorno, accesibilidad y conectividad obtuvieron mayor puntuación, sin embargo, su potencialidad es media. La puntuación de los siete criterios restantes es deficiente, por lo que se puede concluir que el nivel de potencialidad turística del territorio es bajo. Los actores públicos, privados y comunitarios deben trabajar mancomunadamente para mejorar las condiciones que actualmente desfavorecen al territorio como destino turístico emergente.

Shared Vision Based Teamwork Cohesiveness: Catalyst for Organizational Commitment and Organizational Citizenship Behavior (Self Congruence Theory Perspective)
Authors: Amiruddin1 Ahmad , Rongre Yohanis , Sudirman Sudirman , Malik Abdul
Published: February 2022

This paper reviews the important role of Shared Vision Based Teamwork Cohesiveness (SVBTC) in bridging Organizational Commitment (OC) and Organizational Citizenship Behavior (OCB) for employees of an organization. One of the positive behaviors that are expected to grow in an organization is the presence of high OC and OCB in employees. Several previous studies have shown that employees who have good OC are not always supported by good OCB. In this study, a catalyst in the form of Shared Vision Based Teamwork Cohesiveness (SVBTC) is presented from the point of view of Self Congruence Theory (SCT) which is believed to be able to strengthen the relationship between OC and OCB. It is hoped that this paper will provide a new perspective on the factors that can increase OCB for employees in an organization.

The demographic problem today is complex and ambiguous, which can be seen in the example of the Republic of Belarus. When writing the article, the methods of analysis, synthesis, deduction, induction, comparison, and grouping were used. The study is based on the conceptual provisions, ideas, and results of the analysis of the demographic problem in the world, and on the example of the Republic of Belarus, in particular. The object of the study is demographic problems in the Republic of Belarus. In Belarus, the demographic situation is assessed as a serious threat to the sustainable development and national security of the country and is put at the center of its social policy. The main goal of the demographic policy of the republic, both at the national and regional levels, is to create conditions that ensure an increase in the population and an improvement in its age structure. Demographic security can contribute to the creation of the best conditions for Belarusian society – it is an integral part of national security, which determines the state of protection of the socio-economic development of the state and society from demographic threats To achieve an improvement in the demographic situation in the Republic of Belarus, it is necessary to solve the following tasks: strengthening the status of the family, which implies the adoption of a number of measures to stimulate the birth rate; reducing the death rate; creating a mechanism for migration replacement of natural population decline in certain regions, etc.

Scholars has emphasized that community involvement are an important factor in achieving sustainable tourism goals, including community empowerment. The study purpose is to identify community perception of social empowerment resulted from tourism development, to analyze the community involvement in tourism development and to analyze the relationship between community involvement and perceptions related to social empowerment in tourism development. The method employ in this research was a quantitative approach (i.e., household survey). The result showed that majority respondents have a positive perception related social empowerment indicators, including conflict in the area. Community involvement in tourism industry and decision-making process could enhance respondents’ perceptions toward social empowerment indicators. It can be seen from the percentage of the respondents who has positive perception is higher than those who do not involve in tourism industry or decision-making process. The interesting finding is, however, despite the limited resources due to island condition and the ethnic composition that dominate by certain ethnic group, the conflict occurs in the area seems to be low. Since more respondent are disagree if tourism in their area increase the conflict.

Blekok tourism village has become an ecotourism-based mangrove conservation area based on Situbondo Regent Regulation No. 13 of 2017. In less than 30 years, the mangrove forest has decreased by 50% this is due to the rapid population growth and lack of information from the community around the mangrove forest area. Decreasing the quality and quantity of mangroves can have an impact on the survival of the surrounding community and ecosystems that have been formed previously, so calculations are needed as a reference in the use of environmental services in the mangrove forest area. The purpose of this study is to determine the value of direct, indirect and optional economic benefits and to determine the value of the total economic benefits of the mangrove ecosystem economy. The method used was observation and interviews as primary data and literature studies as secondary data. The results obtained are the value of direct benefits of IDR. 681.284.900,00 per year obtained from the catch of crabs and ecotourism. The value of indirect use is obtained as much as IDR. 87.336.000,00 per year which is obtained from catching fish and making breakwaters. The value of choice is IDR. 1,399,923.00 (1 USD= IDR. 14.814,00. The total economic value generated by the mangrove forest area of ​​Kampung Blekok is IDR. 1.027.904.350,00 per year.

Wildlife hunting is important in satisfying people’s need for meat as a source of dietary protein as well as being of economic value to the studied communities. Many people in Indonesian New Guinea rely on the benefits obtained from the extraction of plants and animals in the tropical forests, including hunting. This review aims to synthesise existing knowledge and identify areas that are fundamental to the body of knowledge on Indigenous hunting that has been integrated into many forest people societies in Indonesian New Guinea. People keep a relationship with nature by harmonising Indigenous hunting and cultural background. Available food source from wildlife and limited access to livestock were the major reason to acquire wild animals for consumption through hunting. Throughout of Indonesian New Guinea, the commercial hunting provide more opportunities for income generation. Indigenous hunting has long been part of cultural life of forest, providing a source of dietary protein to the household, and offer forms of income generation to the studied communities.

Background: De novo metastatic breast cancer is seldomly encountered in patients visiting doctor’s clinics for the first time. This article reports a case of cervical/submandibular metastatic breast cancer treated with neoadjuvant endocrine therapy (NET) with anastrozole (ANA). Case description: We herein report on a patient affected by HR+, HER2−, and metastatic breast cancer treated with NET that presented after 6 months with the possibility of breast-conserving surgery due to clinical and radiological complete response, revealing after surgery pathological complete response. Conclusion: Even for patients with metastatic luminal breast cancer, NET with an aromatase inhibitor, especially ANA, is a good option for postmenopausal women with fewer side effects and allowing for breast-conserving surgery with less morbidity when comparing with chemotherapy and yet yielding good results.

Objectives: To analyze the aspects of mammography in the early screening of breast cancer, in Brazil, from 2015 to 2019. Methodology: Descriptive epidemiological study, with secondary data extracted from the Department of Informatics of the Brazilian Unified Health System (DATASUS), through the Cancer Information System (SISCAN). Information related to mammography examinations was classified by place of care according to the clinical indication (screening or diagnosis), age group (70 years), previous mammography, high risk of breast cancer (BC), examination completion time, and the Breast Imaging Reporting and Data System (BI-RADS®), which classifies radiological findings as 0 (undefined), 1 (negative), 2 (benign), 3 (probably benign), 4 (suspect), 5 (highly suspicious), and 6 (diagnosed with cancer). Results: Between 2015 and 2019, 3,031,607 mammograms were performed in Brazil, of which 2,955,262 occurred by screening and 76,345 by clinical diagnostic indication. Among the screening mammograms, 63.2% were performed on women in the age group recommended by the Brazilian Ministry of Health (MS), from 50 to 69 years old. The previous history of this examination was confirmed by 2,300,995 women, where 17.5% were at high risk for BC. For the examination time, 1,396,105 mammograms took place within 30 days, and 775,971 and 859,531 over 60 days. BI-RADS was higher in category 2 (1,520,469 mammograms), followed by category 1 with 1,071,514 of mammograms, and in the target population recommended by the Brazilian Ministry of Health, the largest number of tests was concentrated in BI-RADS category 2 with 34.2%. Conclusion: Characterization of the main aspects involved in mammography, such as age, high risk, and among others, allows to infer that the early screening of BC when prioritized by public health policies, aiming at the promotion of women’s health, impacts on the early detection and the reduction of the incidence and mortality by BC in women in Brazil.

Published: February 2022

This study is targeting at portraying the sorts and the errors of discourse markers made in the articles on Hamlet drama composed by the 6th semester students of English education program at University of Mataram in the academic year 2019/2020. The technique of conducting this investigation is a blended strategy or mix of qualitative and quantitative techniques. The data were gathered from 26 students’ articles. The result of this study showed that all the types in three functional classes of discourse markers by Bruce Fraser (2009) were used by students in their articles. They are Elaborative Discourse Markers with total number of occurrences 200 times (43.20%), Contrastive Discourse Markers with total number of occurrences 169 times (36.50%), and Inferential Discourse Markers with total number of occurrences 94 times (20.30%). The researcher found that Elaborative Discourse Markers are most frequently employed by students to elaborate the ideas. Furthermore, there are some errors in student’s articles related to Kao and Chen's theory (2011) about the six types of misuse patterns. Turns out three of six misuse patterns occur in students’ articles such as distraction, wrong relation, and semantic incompletion. There are no surface logicality, non-equivalent exchange, and overuse occurred in students’ articles.
