Communication in the ICU: An Unintended Nocebo Effect?

To identify medical phrases utilized by the critical care team that may have an unintended impact on the critically ill patient, we administered an anonymous survey to multi-professional critical care team members. We elicited examples of imprecise language that may have a negative emotional impact on the critically ill. Of the 1600 providers surveyed, 265 offered 1379 examples (912 unique) which were clustered into 5 categories. Medical jargon (eg, "riding the vent") was most prevalent (n = 549). There were 217 negative suggestions (eg, "you will feel a stick and a burn"). Hyperboles (eg, "black cloud") were common (n = 198) while homonyms (ie "he fibbed") accounted for 150 examples. Phrases such as "code brown in there" were categorized as metonyms (n = 144). 121 metaphors/similes (eg, "rearranging deck chairs on the Titanic") were provided. Phrases that have the potential to negatively impact critically ill patient perceptions are commonplace in critical care practice. Whether these everyday communication habits lead to an unintended nocebo effect on mental health outcomes of the critically ill deserves further study.

Impact of quintessence and cloud of strings on self-consistent d-dimensional charged thin-shell wormholes

This article evaluates the stability constraints of higher-dimensional geometry of thin-shell wormholes developed from the two equivalent copies of inner and outer d-dimensional charged anti-de Sitter black holes bounded by a cloud of strings and quintessence. Such geometrical structures are built using a cut-and-paste method that joins two identical forms of black hole solutions at the hypersurface. We develop the equation of motion for the constructed wormholes and then use the linear radial perturbation approach to examine the stable configuration. The stability constraints depend on the dimensions of the black holes, cloud, and quintessence parameters. It is worth mentioning that the possibility of a stable structure is greatest for the choice of d-dimensional charged anti-de Sitter black holes with quintessence and a cloud of strings.

'A Constant Black Cloud': The Emotional Impact of Informal Caregiving for Someone With a Lower-Grade Glioma.

Those closest to people with lower-grade gliomas (LGGs) often assume the role of informal caregiver (IC). The additional responsibilities mean ICs of people with cancer can experience adverse impacts on their own lives. We explored the emotional impact of informal caregiving for people with LGGs. This was a descriptive qualitative study within the multi-method Ways Ahead project. We conducted semi-structured interviews with individuals from the United Kingdom, who currently, or in the past 5 years, informally cared for someone with an LGG. Interviews encompassed experiences of emotional impact as a consequence of caregiving for someone with an LGG. Inductive thematic analysis was undertaken. We interviewed 19 ICs (mean age 54.6years; 14 females, 5 males). Participants reported substantial emotional impact. Four themes and associated subthemes were generated: Emotional responses to the illness (e.g. feeling helpless), Emotional responses to the unknown (e.g. anxiety about future uncertainty), Emotional consequences of care recipient changes (e.g. challenges of changed relationship dynamics), and Emotional weight of the responsibility (e.g. feeling burnout). Emotional impact in one area often exacerbated impact in another (e.g. future uncertainty impacted feelings of helplessness). Participants detailed the factors that helped them manage the emotional impact (e.g. being resilient). ICs of people with LGGs can experience wide-ranging emotional responses to and impacts of the illness, uncertain prognosis, care recipient changes, and the toll of caregiving. Adjustment and resilience are key protective factors, though further consideration of ways to identify and fulfil the emotional support needs of ICs of people with LGGs is required.

Влияние лермонтовской традиции на современного иранского поэта Шафии Кадкани

Man and nature are two inseparable elements of the world, and the unbreakable connection and coexistence between them is the origin of all kinds of literary works. From ancient times to the present day, we often see poems about nature both in Russian and Persian literature. Using the Natural objects and phenomena in the form of myths and symbols in literary works and giving them personality have various reasons, including political ones. Sometimes poems may be composed under the influence of a poet from another country. This influence can be seen in contemporary Iranian literature. Among the contemporary Iranian poets who are very familiar with the ideas and works of Russian poets and writers is the Iranian naturalist (пейзажист) poet Shafiei Kadkani. He composed his poem “Happy Journeys!”) based on Lermontov’s “The Rock” and “The black Clouds” poems. Both poets have used natural images such as plant (растение), breeze (ветерок), blossoms (цветения), rain (дождь), desert (пустыня), dust (пыль), horror desert (пустыня ужаса), rock / cliff (утес) and black clouds (тучи), which have a symbolic role. By comparing the poems, we can see that they are similar in terms of content and have the same message. And some of the symbols of Shafiei Kadkani are the same as the symbols of Lermontov, such as the desert, or they are chosen in terms of meaning very close to the symbols of Lermontov, such as “rock / cliff and milkvetch” or “small clouds and breeze”, as well as the dynamic movement of small clouds and breeze, which are the symbol of transition and change. Like Lermontov, Shafiei Kadkani also complains about the situation of his society, but symbols like “blossoms and rain” at the end of Shafiei Kadkani’s poem, unlike Lermontov’s poems, promise the morning of freedom, prosperity and transition, but with doubts.

Continuous phase transition of the de Sitter spacetime with charged black holes and cloud of strings and quintessence* *Supported by the Natural Science Foundation of China (11705106, 12075143), the Scientific Innovation Foundation of the Higher Education Institutions of Shanxi Province (2020L0471, 2020L0472), the Science Technology Plan Project of Datong City, China (2020153), the Science Foundation of Shanxi Datong University (2022Q1,

Recently, some meaningful results have been obtained by studying the phase transition, critical exponents, and other thermodynamical properties of different black holes. Especially for the Anti-de Sitter (AdS) black holes, their thermodynamical properties nearby the critical point have attracted considerable attention. However, there exists little work on the thermodynamic properties of the de Sitter (dS) spacetime with black holes. In this paper, based on the effective thermodynamical quantities and the method of the Maxwell's equal-area law, we explore the phase equilibrium for the de Sitter spacetime with the charged black holes and the cloud of string and quintessence (i.e., C-dSSQ spacetime). The boundaries of the two-phase coexistence region in both and diagrams are obtained. The coexistent curve and the latent heat of phase transition for this system are also investigated. Furthermore, we analyze the effect of parameters (the state parameter ω and the ratio of two horizon radii /) on the two-phase coexistence region boundary. The results indicate that the phase transition in C-dSSQ spacetime is analogous to that in a van der Waals fluid (vdw) system, which is determined by the electrical potential at the horizon. These results are helpful for understanding the basic properties of black holes and are also of great value for the establishment of quantum gravity.

“Recycling rice straw as a type of agricultural solid waste” Alternatives of using rice straw in Building construction as a tool to protect the environment in Egypt.

The research aims to develop alternatives of using rice straw inconstruction as a tool to preserve the environment in Egypt. where the rice straw isone of the types of solid agricultural waste, which is produced in Egypt in largequantities, as a result of the lack of strategy by the State for how to collect ricestraw from farmers to recycling to benefit from them. Farmers burn it, which causesthe formation of a black cloud annually in Egypt and resulting environmentalproblems and health damage. Therefore, it was necessary to research how to get ridof rice straw by making use of it in recycling and using it in different ways inconstruction work in order to maximize the economic return from it as well as topreserve the environment in Egypt. The research paper deals with alternatives tobenefiting from rice straw, and these alternatives can be considered as amethodology or framework that the government may benefit from in addressing theenvironmental problem facing the country annually.

Black clouds in surgery: A study of surgical resident workload and burnout

BackgroundThe concept of a ‘black cloud’ is a common unfounded perception in the healthcare workforce that attributes a heavier workload to specific individuals or teams. Prior studies in non-surgical disciplines have demonstrated that ‘black cloud’ perceptions are not associated with workload, albeit such perceptions may influence behavior. The influence of ‘black cloud’ perceptions on surgical resident workload and burnout remains to be investigated. This study assesses the associations between ‘black cloud’ self-perception with actual workload and burnout among surgical residents in different specialties. MethodsA cross-sectional survey study of postgraduate year (PGY) 2 and 3 residents enrolled in different surgical residencies at the Icahn School of Medicine at Mount Sinai was conducted between September–November 2021. ResultsThe survey response rate was 62.1% (41/66). 46.3% of respondents were female. The majority of subjects were single (61%) and PGY2 trainees (56.1%). In a multivariate regression analysis demographic factors and workload variables, such as the number of pages responded, notes, and amount of sleep, were not significant predictors of a ‘black cloud’-self-perception. A significantly lower Burnout Index Score (BIS) was observed among females (p< .001). A significantly higher BIS was observed among residents who are single (p = .003), training in general surgery (p = .02), and orthopedic surgery (p = .03). There was no significant association between ‘black cloud’ self-perception and BIS. DiscussionThe findings demonstrate that a ‘black cloud’ self-perception is not associated with a high workload and burnout among surgical residents. Gender, marriage/domestic partnership, and certain surgical specialties influenced burnout among the study cohort.

Quasi-periodic oscillations of test particles and red–blue shifts of photons in the charged-Kiselev black hole with cloud of strings

Here we examine the circular motion of test particles and photons in the spacetime geometry of the charged black hole surrounded by quintessence and clouds of strings for the equation of state parameter ω q = − 2 / 3 . We observe that there exist stable circular orbits in this geometry for very small values of the quintessence and the string cloud parameters, i.e., 0 < γ < < 1 and 0 < α < < 1 . We also observe that if the values of γ and α get increase, then the test particle can more easily escape the gravitational field of the black hole. While the effect of the charge Q of the black hole on the effective potential is just opposite to that of the parameters γ and α . Further we investigate the quasi-periodic oscillations of test particles near the stable circular orbits in the vicinity of the black hole considered here. With the increasing values of Q , the stable circular orbits move away from the central black hole, therefore, one can observe lower epicyclic frequencies away from the central gravitating source with the increase in the values of Q . The stable circular orbits get closer to the central object as the parameters γ and α increases. Thus, one can observe the epicyclic frequencies closer to the central object and would be higher as compared to the epicyclic frequencies observed in the case of pure Riessner-Nordstrom black hole, i.e., without quintessence and string clouds. The redshift parameter z , of the photons emitted by the charged test particles moving in the stable circular orbits around the charged quintessential black hole with clouds of strings, increases with an increase in the values of the parameter α and decreases with an increase in the values of the charge Q of the black hole. For different values of the parameter γ , it stays constant. In the study of the Banados-Silk-West (BSW) process, in the spacetime geometry of the charged-Kiselev black hole with string cloud, we notice that the centre-of-mass energy at the horizon of the black hole increases indefinitely if the charge of one of the colliding particles attains its critical value. We observe that the effective force on the test particles decreases as the values of the parameters γ and α go on increasing, and it increases with the increasing values of the charge Q of the black hole. For a better understanding of the study, we show the dependence of the radii of the circular orbits, energy and angular momentum of the particles, effective potential, effective force, quasi-periodic oscillations and red-blue shifts of photons of the test particles in the circular orbits on the parameters α , γ and Q graphically. • We have examined the circular motion of test particles and photons for the spacetime with a charged black hole surrounded by quintessence and clouds of strings. • We observe that if the values of γ and α increase, the test particle can more easily escape the gravitational field of the black hole. • With the increasing values of Q , the stable circular orbits move away from the central black hole. • The epicyclic frequencies closer to the central object would be higher than the epicyclic frequencies observed in the case of the pure Riessner-Nordstrom black hole. • The redshift parameter z of the photons emitted by the charged test particles moving in the stable circular orbits around the black hole.

Looking for Justice in the Black Cloud: Providing Justice for Victims of Sexual Harassment in Indonesia

According to Komnas Perempuan, sexual harassment is a sexual act through physical or non-physical touch that targets the sexual organs or sexuality of the victim. This includes using whistles, flirting, sexually suggestive speech, displaying pornographic material and sexual desires, touching or touching body parts, gestures or gestures of a sexual nature that cause discomfort, be offended, feel humiliated, and possibly cause health problems. and safety. The law also has its own interpretation of sexual harassment. In the Criminal Code (KUHP) there is no term sexual harassment, but in Article 289 to Article 296 of the Criminal Code it is called obscenity. R. Soesilo in the book “KUHP and its comments”, sexual harassment includes acts that violate a sense of decency, or other vile acts, and all of them are in an environment of sexual lust. For example, kissing, groping the genitals, groping the breasts and so on. The term sexual harassment, according to Ratna, refers to sexual harassment which is defined as unwelcome attention or legally defined as an imposition of unwelcome sexual demands or creation of sexually offensive environments.&#x0D;

Neurotransmitters: A Computational and bio mathematical approach at the time of COVID-19

COVID-19 has already swept millions of lives and created the deep black cloud made up of negative emotions. Acanthus ilicifolius was used as Traditional Indian medicine (TIM) and Traditional Chinese medicine (TCM). The plants showed many clinical properties. Still, the neurological related functions and disorders are not well explored in this plant. Complex interplay of positive and negative emotions orchestrated by intricately associated neuronal circuits, neurotransmitters coupled with endocrinal in- fluence holds responsible for human behavior, considered as the root of human civilization, is currently facing existential crisis during COVID-19 pandemic. In the present study, an attempt was made to identify the interaction between A. ilicifolius natural compounds and Echinacoside as reference compounds were to study the neurotransmitters functions through biomathematical and computational method. Initially, in silico molecular docking was performed to identify the potent natural compounds against neurological disease. The results show among 8 natural compounds, 26.27-Di(nor)-cholest-5,7,23-trien-22-ol, 3-methoxymethoxy, Cholest-5-en-3-ol (3, Beta.)-, carbonochloridate, Cholesterol and Echinacoside exhibited maximum interaction with all the target proteins. Especially, Echinacoside exhibited the maximum interaction with (Serotonin) 5-hydroxytryptamine receptor 2A (-17.077), Sodium-dependent serotonin transporter (-15.810) and (Histamine) Histamine H2 receptor (-17.556). These two neurotransmitters act as a major concern related to the mental disorders and neurological functions. The natural compounds may potent inhibitor for neurological disorders.

Thunderstorm Activity over the Qinghai–Tibet Plateau Indicated by the Combined Data of the FY-2E Geostationary Satellite and WWLLN

Thunderstorm activity over the Qinghai–Tibet Plateau (QTP) has important climatic effects and disaster impacts. Using the thunderstorm feature dataset (TFD) established based on the black body temperature (TBB) and cloud classification (CLC) products of the Fengyun-2E (FY-2E) geostationary satellite, as well as the lightning data of the World Wide Lightning Location Network (WWLLN), the temporal and spatial distributions and some cloud properties of the thunderstorms over the QTP were analyzed. Approximately 93.9% and 82.7% of thunderstorms over the QTP occur from May to September and from 12 to 21 o’clock local time, and the corresponding peaks are in August and at 14:00, respectively. There are three centers featuring frequent thunderstorms in the southeast, south-central, and southwest regions of the QTP. The average thunderstorm cloud area (the region with TBB ≤ −32 °C) is 1.8 × 104 km2. Approximately 32.9% of thunderstorms have strong convective cells (SCCs) composed of areas with TBB ≤ −52 °C. The average number and area ratio of SCCs are 3.6 and 25.4%, respectively, and their spatial distribution is given. The average cloud area and the number and area ratio of SCCs of extreme-lightning thunderstorms (thunderstorms with the top 10% of lightning numbers) are approximately 30.0, 3.9, and 1.5 times those of normal thunderstorms. The spatial distribution of the thunderstorm activity is quite different from that of lightning activity given by the Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) over the northeastern and southwestern QTP, which may mean that the convection intensity, cloud structure, and charge structure of the thunderstorms over the QTP are different between different regions and seasons.

Indigenous Knowledge About Disaster in Folk Prose Narratives of Indonesian Coast

Indonesian people consists of various ethnic groups living in urban, rural, mountainous, and coastal areas. The people who inhabit each region have stories that describe the topography of the region and its culture. An example is people from coastal areas. The location of their residences which are close to the ocean makes them experts in recognizing natural signs and disaster characteristics from the sea. Their knowledge is shared with the social environment by verbal. One type of oral tradition originating from the natives is folk prose narratives such as legends, fairy tales, and stories of the origin of a place. This study aims to explore indigenous knowledge in folk prose narratives from the Indonesian coast. The results showed that the knowledge contained in folk prose narratives was how to recognize disaster signs from the sky (roaring wind, lightning flashes, pitch-dark sky, black cloud, and very heavy rain), disaster signs from the sea (low tides, hurricanes), ways to save yourself (climbing trees, climbing hills, and going to higher ground), and disaster prevention (not killing animals and cutting down trees carelessly). The conclusion is indigenous knowledge about disasters in folk prose narratives from the Indonesian coast is how to recognize natural signs, how to save themselves, and mitigation. The findings in this study are that Indonesian ancestors had knowledge in making flying vehicle and making fish feed on natural ingredient (chicken feathers).

A CNN-based multi-task framework for weather recognition with multi-scale weather cues

Automatic image-based weather recognition has a great significance in the practical use of computer visual applications. The weather recognition approaches via multi-task learning obtain the description of weather conditions by jointly tackling weather-cue segmentation task and weather classification task. However, the existing approaches neglect the multiple scales of weather cues, which may decrease the ability to deal with both large and small weather cues in weather-cue segmentation. They also fail to assign appropriate weights, which the multi-task learning for weather recognition relies on, to the two tasks. To address these problems, we propose a novel end-to-end Convolutional Neural Network (CNN)-based Multi-task Weather Recognition Network with multi-scale weather cues (CMWRN). Specifically, in the weather-cue segmentation task, we propose to segment weather cues, e.g. blue sky and black clouds, by capturing multi-scale weather-cue features. Arbitrary-scale weather-cue regions in the outdoor images can be accurately and effectively classified via resampling the weather-cue features at multiple scales. In the weather classification task, a generalized pooling method is introduced to generate more discriminative weather representations. To further promote the weather classification, the multi-scale weather-cue features are exploited to provide weather clues for weather representations. Moreover, we develop an adaptive weighting scheme to automatically balance the weather classification task and weather-cue segmentation task for more effective training. Compared with the state-of-the-arts, experimental results on two public available benchmark datasets demonstrate the superior performance of our approach.

Black Clouds and Silver Linings: Exploring the Psychosocial Consequences of the COVID-19 Pandemic on Expatriates Living in Hong Kong

Background: While global media, international and local health organisations, epidemiologists, and opinion makers disseminate regular updates on the spread and mortality of COVID-19, the psychosocial effect of the pandemic is often neglected. This is amplified for expatriates living outside their native country as stringent quarantine measures make travelling to their home countries prohibitive, if not impossible, in terms of time and money. Objective: The aim of this study was to understand the psychosocial consequences of the COVID-19 pandemic on expatriates living in Hong Kong. Method: An exploratory qualitative research design was employed. Qualitative data from semi-structured interviews and surveys were analysed using template analysis. Findings: Data revealed that COVID-19 adversely affected the mental and social wellbeing of most of the respondents. There were silver linings in finding new ways to connect, appreciating a slower pace of life and the opportunity to reassess priorities, although the black clouds of separation from family, concern for youth, missing milestones and mental & financial concerns dominated most of the data. These negative consequences were exacerbated by the lack of reasonableness, inclusivity, openness and transparency of the COVID-19 restrictions and regulations. Conclusion: As the psychosocial consequences of the pandemic are expected to continue for some time, this study has implications for public health policy and practice in HK, and internationally, in planning how to mitigate the negative effects of the pandemic.

Experimental determination of the lower explosion limit for two gasoline samples

The explosive atmosphere may be caused by flammable gases / vapours or combustible dust. If the amount of the substance, mixed with air, is sufficient, then a source of ignition is needed to cause an explosion. Liquids (for example petrol and other fuels) and solvents from industrial products emit flammable vapours which, when mixed with air, can ignite or explode. At normal temperatures, flammable liquids can emit enough vapours to form combustible mixtures with air, heat, and often thick, black, and toxic clouds of smoke. The behaviour of a fuel-oxidant mixture is characterized by certain explosions parameters, including explosion limits, which characterize the range of concentrations in which combustion propagates at very high speeds. For this work were performed experimental determination of the lower explosion limit for two commercial gasoline samples.

COVID-19 in India: Weighing Schools Reopening Amid Black Clouds of Third Wave Hovering Around

The Coronavirus disease (COVID-19) wreaked havoc across the globe with the onset of year 2020, which posed an extra ordinary situation in front of mankind. The black clouds of third wave are still hovering around us. We all have seen a lot of ups and downs with respect to every front of this disease including restriction of movements and closure of schools. In the current scenario, many voices are being heard to reopen the school with a justification that if we don’t open the schools then we going to witness a generation that has missed months or years of schooling. In this regard, we must weigh the decision or consideration of reopening of schools against amid third wave predictions in near future. Read more...

Proficient Masked Face Recognition Method Using Deep Learning Convolution Neural Network in Covid-19 Pandemic

The COVID-19 pandemic is an incomparable disaster triggering massive fatalities and security glitches. Under the pressure of these black clouds public frequently wear masks as safeguard to their lives. Facial Recognition becomes a challenge because significant portion of human face is hidden behind mask. Primarily researchers focus to derive up with recommendations to tackle this problem through prompt and effective solution in this COVID-19 pandemic. This paper presents a trustworthy method to for the recognition of masked faces on un-occluded and deep learning-based features. The first stage is to capture the non-obstructed face region. Then we extract the most significant features from the attained regions (forehead and eye) through pre-trained deep learning CNN. Bag-of- word paradigm to has been applied to the feature maps to quantize them and to get a minor illustration comparing to the CNN’s fully connected layer. In the end a Multilayer Perceptron has been used for classification. High recognition performance with significant accuracy is seen in experimental results.

Time Optimization of Unmanned Aerial Vehicles Using an Augmented Path

With the pandemic gripping the entire humanity and with uncertainty hovering like a black cloud over all our future sustainability and growth, it became almost apparent that though the development and advancement are at their peak, we are still not ready for the worst. New and better solutions need to be applied so that we will be capable of fighting these conditions. One such prospect is delivery, where everything has to be changed, and each parcel, which was passed people to people, department to department, has to be made contactless throughout with as little error as possible. Thus, the prospect of drone delivery and its importance came around with optimization of the existing system for making it useful in the prospects of delivery of important items like medicines, vaccines, etc. These modular AI-guided drones are faster, efficient, less expensive, and less power-consuming than the actual delivery.

Beautiful Black Cloud of Modern Egyptian Art

This paper contextualizes the Art and Liberty group within the scope of Egyptian modern art. In doing so, it argues that this movement does not simply translate “central” Parisian surrealism to so-called “peripheral” Cairo. Rather, Art and Liberty represents a pivot in a continuum of Egyptian modern art and an important node in the transnational expansion of surrealism in the late 1930s. To situate the movement in a larger arc, this article spans the 1910s to the 1950s. An analysis of famous sculptor Mahmoud Mukhtar (1891–1934) first represents the nationalist and classicist origins of Egyptian modern art. Second, an examination of the Long Live Degenerate Art manifesto explicates the complexity of the group’s ideology in its early days. Third, Kamel Telmisany’s (1915–72) shift from expressionist painter and draftsman to realist filmmaker signals how aesthetics and mediums adapted to new iterations of the Art and Liberty ideology. Fourth, painter Abdel Hadi el-Gazzar (1925–66) and the Contemporary Art Group epitomize the impact of Art and Liberty after World War II. This chronological progression illustrates how the Egyptian Art and Liberty group reacted vociferously against nationalism in politics and art, both locally and regionally. In doing so, they shifted the audience of modern Egyptian art and created a new, transnational public. For these reasons, the author calls this movement the “Beautiful Black Cloud” of modern Egyptian Art. It was violent, stormy, and did not always look “pretty,” but it was beautiful in its legacy.
