Crítica à utopia/crítica à modernidade: sobre o alcance e as limitações da teoria da história de Reinhart Koselleck diante da atual crise do tempo
Authors: Rodrigues da Cunha Marcelo Durão , Perini Júlia Freire 
Published: January 2022

Este artigo tem o objetivo de esclarecer o lugar ocupado pela crítica à utopia nos escritos teóricos de Reinhart Koselleck, buscando explorar aquilo que é entendido pelo historiador alemão como o fenômeno de temporalização da utopia. Para tanto, procuramos em um primeiro momento esclarecer o significado da noção de temporalização na obra desse autor, a entendendo como parte central para a compreensão da teoria koselleckiana dos tempos históricos e de sua crítica à modernidade. Em seguida, analisamos a importância assumida pela crítica à utopia no trabalho do historiador desde a escrita da obra Crítica e crise (1959), a compreendendo como parte de sua tentativa de apreensão dos fenômenos da despolitização e do surgimento das modernas filosofias da história no século XVIII europeu. Finalmente, o trato com esses pontos é o que nos permite desenvolver os dois objetivos gerais pretendidos com a escrita do presente artigo: demonstrar a centralidade da noção de utopia – e de sua crítica – nos escritos teóricos de Koselleck e discutir em que medida as soluções empreendidas pelo historiador ao esgotamento da lógica moderna de interpretação utópica da mudança histórica se constituem como respostas plausíveis para se superar a crise contemporânea do tempo, sobretudo, nas periferias do mundo ocidental.

Authors: Silva Wady Wendler Soares Veras e , Rocha Maria Izabel Félix , Teixeira Kelly Sivocy Sampaio , Filho Francisco Artur e Silva 
Published: January 2022

Resumo: O papel do enfermeiro na unidade de diálise peritoneal (DP) é extremamente relevante, pois ele planeja os cuidados, orientações e soluciona problemas que interfiram no método dialítico. O objetivo desse estudo é descrever o papel do enfermeiro na prestação da assistência em pacientes renais crônicos submetidos a DP. Esse estudo apresenta pesquisas nas bases de dados PubMed, LILACS e SciELo, no período de 2009 a 2019. Com manuscritos no idioma português, inglês e espanhol, os descritores utilizados foram “Diálise peritoneal”; “Cuidados de Enfermagem”; “Insuficiência Renal crônica” e “Peritoneal Dialysis”; “Nursing Care”; “Renal Insufficiency, Chronic”. Depois das buscas nas bases de dados selecionadas, foram escolhidos 147 artigos. Ademais, foi realizada uma análise que resultou na amostra de 10 documentos. Após a leitura completa dos artigos selecionados, foram elaboradas quatro categorias de análise, que são: “A DP como escolha do paciente por modalidade de tratamento”; “Orientações necessárias que o enfermeiro deve fornecer para os pacientes em DP”; “Principais diagnósticos de enfermagem e intervenções que o enfermeiro pode realizar em pacientes com DP”; “A assistência prestada pelo enfermeiro ao paciente em processo de DP”. Observou-se que a maioria dos estudos destaca a importância do enfermeiro no auxilio das orientações e cuidados ao paciente dialítico, como a higienização das mãos, dos materiais utilizados, cuidados no domicilio e do local da inserção do cateter. Por fim, o enfermeiro é imprescindível no tratamento da DP, pois o mesmo facilita e traz uma maior eficácia ao processo, melhorando a qualidade de vida e diminuindo possíveis complicações.
Deep-learning-based colorimetric polarization-angle detection with metasurfaces
Authors: Yang Bo , Ma Dina , Liu Wenwei , Choi Duk-Yong , Li Zhancheng , Cheng Hua , Tian Jianguo , Chen Shuqi 
Published: January 2022

Polarization plays a key role in both optics and photonics. Generally, the polarization states of light are measured with birefringent or dichroic optical elements paired with a power meter. Here we propose a direct polarization detection method based on colorimetric asymmetrical all-dielectric metasurfaces to obtain the polarization angles of the incident light. The independently tunable periods and diameters along the

x

and

y

axes enables double-layer nanopillars to realize high-performance dual-color palettes with arbitrary combinations under orthogonal polarization states. The polarization detection network based on residual networks is used to deeply learn the regulations between color palette variations and incident polarization angles, which can accurately recognize extremely slight polarization variations in about 1 s with an accuracy of 81.4% within 0.7° error and 99.5% within 1.4° error. Our strategy significantly improves the compactness of polarization detection, and it can be readily expanded to polarization distribution measurement and colorimetric polarization imaging on an intelligent platform.
Assessing prevalence, knowledge and use of cognitive enhancers among university students in the United Arab Emirates: A quantitative study
Authors: Sharif Safia , Fergus Suzanne , Guirguis Amira , Smeeton Nigel , Schifano Fabrizio 
Published: January 2022

Background
Cognitive enhancers (CE) are often used to improve memory, alertness and cognitive capacity. These products are commercially and pharmaceutically available. Due to high academic pressure, university students are at risk of CE misuse. However, data regarding this issue are limited, especially in the United Arab Emirates (UAE).

Aims
To assess the prevalence of CE intake; evaluate students’ knowledge of these substances; and identify student characteristics associated with CE usage.

Method
A cross sectional study based on a validated online survey that was distributed using university-licensed software (Qualtrics) as a direct web link via email and social media to all Medical, Pharmacy, Dentistry, Nursing and Engineering students enrolled in six UAE universities. Associations between student characteristics and CE use were investigated using the chi-squared test and multiple logistic regression. Reasons for CE use, temporal patterns of use, details regarding purchase and types of CE used were compared by gender.

Results
One quarter of students had used CEs. There was a clear difference between users and non-users in terms of gender (p<0.001). CE users were disproportionately represented by students from either UAE or other Arab countries (p<0.001), and by students of Medicine, followed by Pharmacy, Dentistry, and Engineering (p<0.001). CE use increased with year of study, reaching the highest level in the fourth year (p<0.001), which for most programmes is the final year. Modafinil was self-administered, especially in males, for concentration and alertness; B12 was typically taken by female students for academic performance and concentration; and high-dosage caffeine compounds were ingested to improve alertness levels. Use of the internet for both obtaining information and purchasing CEs was frequently reported. Multiple logistic regression analysis showed that gender, nationality, and year of study were associated with CE use among UAE university students.

Conclusions
Universities need to address the prevalence of CE use amongst their students by providing effective support programs.

Authors: Trivedi Jaimin R. , Pahwa Siddharth V. , Whitehouse Katherine R. , Ceremuga Bradley M. , Slaughter Mark S. 
Published: January 2022

Background
The objective of this study was to evaluate annual heart transplant volumes and 3-year post-transplant outcomes since establishment of United Network for Organ Sharing (UNOS) database stratified by race.

Methods
The UNOS thoracic transplant database was evaluated for adult patients since 1987. The available database was then stratified by Race: Black, White and Other and era of transplant: group 1(1987–1991), group 2(1992–1996), group 3(1997–2001), group 4(2002–2006), group 5(2007–2011), group 6(2012–2016) and group 7(2017 and later). Demographic and clinical factors were evaluated.

Results
A total of 105,266 adults have been listed since 1987 and 67,824 have been transplanted. Of the transplanted patients 11,235 were Black, 48,786 White and 6803 were of Other race. The proportion of Black patients listed increased from 7% in 1987 to 13.4% in 1999 and 25% in 2019 and those transplanted increased from 5% in 1987 to 13.4% in 2001 and 26% in 2019. The survival of Black patients gradually improved.

Conclusion
Historically, fewer Black patients received cardiac transplantation however, their access gradually improved over the years and account for over 25% of cardiac transplantations performed in recent years. The historically poor survival of Black patients has recently improved and became comparable to the rest.
Gravitation near the Schwarzschild radius
Authors: L. Khokhlov D. 
Published: January 2022

The problem of gravitation near the Schwarzschild radius is addressed. The pressure due to free fall velocity is introduced. At the Schwarz-schild radius, this pressure produces the force balancing the gravity thus stopping the collapse of the matter. The minimum radius of the source of gravity is defined as a radius at which the proton reaches the Planck energy. The compact object as a thin shell at the minimum radius is considered. The proton is assumed to decay at the Planck scale into positron and hypothetical Planck neutrinos. Under accretion onto the compact object, half the protons decay, and the other protons retain at the minimum radius.Â Â
Periodic orbit in the photo-gravitational restricted three body problem around the collinear Lagrangian points when more massive primary is an oblate spheroid and source of radiation
Authors: John Derick , Krishan Sharma Ram 
Published: January 2022

The circular Restricted Three Body Problem is considered with the more massive primary as an oblate spheroid and source of radiation. A new mean motion expression given by n2=1+6A is used in the present study, when the secular effect of the oblateness on the mean motion, argument of perigee and right ascension of the ascending node is considered. The locations of the collinear Lagrangian points are found. It is found to have some variation from the previous study conducted on the same because of the new mean motion that is considered in this study. The variations of the location of the Lagrangian points due to the unperturbed as well as the perturbed problem due to oblateness and radiation pressure are studied. A study on the eccentricity e and angular frequency s at L1, L2 and L3 is carried out. It is observed how the change in effect of oblateness and radiation pressure has affected the location, angular frequency and eccentricity at L3, though there are only small changes noticed in the case of L1 and L2.Â Â
Determination of fluorescence lifetimes of fluorescein from fluorescence quenching data
Authors: Ogunsipe Abimbola , Opeolu Olutunji 
Published: January 2022

The fluorescence quenching of fluorescein by 1,4-benzoquinone (BQ) in five solvents â€“ methanol, ethanol, phosphate buffer saline (PBS, pH 7.4), N,N'-dimethylformamide (DMF) and dimethylsulphoxide (DMSO) is hereby investigated. Fluoresceinâ€™s fluorescence was effectively quenched by BQ, and the quenching was dynamic (purely collisional) within the BQâ€™s concentration range (0.001 to 0.004 M) used in this work. Accordingly, the quenching data were in conformity with the Stern-Volmerâ€™s model. Stern-Volmerâ€™s constant (KSV) values range between 17.4 in DMSO and 43.4 in methanol. KSV values, together with the calculated bimolecular rate constants (kD) in the respective solvents, were used to semi-empirically estimate the fluorescence lifetimes (tF) of fluorescein in the individual solvents. Just as for KSV values, tF values are solvent-viscosity dependent, with the lowest values being obtained in methanol and the highest in DMSO, which are the least and most viscous solvents respectively. tF values obtained in this work are 3.55, 3.71, 3.78, 4.13 and 4.51 ns (in methanol, PBS 7.4, ethanol, DMF and DMSO, respectively).Â Â Â

Published: January 2022

Two simple, rapid, sensitive and accurate spectrophotometric methods are described for the determination of Pregabalin (PRG) in bulk and pharmaceutical formulations. The methods are based on the reactions of the drug with bromocresol purple (BCP) and bromocresol green (BCG) in buffered hydrochloric acid solutions at pH 1.2 to give coloured ion-pair complexes extractable with chloroform. The coloured products are quantitated spectrophotometrically at 431 nm with BCP and 444.80 nm with BCG. Beer's law is obeyed in the concentration range 10-50 Âµg/ml with both reagents. Recovery studies gave satisfactory results indicating that none of common additives and excipients interfere the assay method. The proposed methods are found to be simple, accurate and reproducible that was successfully applied for the analysis of capsule formulations. The developed methods are easy to use, accurate and highly cost-effective for routine studies relative to HPLC and other techniques.Â Â Â

Authors: Heidari Alireza , Peterson Victoria 
Published: January 2022

In this research, poly (D, L-lactide-co-glycolide)-block-poly (ethylene glycol), (PLGA-PEG) nanoparticles (NPs) of less than 195 nm in diameter containing of Naringenin (NRG) a naturally flavonoid were synthesized. Encapsulated form NRG improves its medical properties and solubility. The therapeutic efficacy of the encapsulated naringenin (NRG-NPs) and NRG on human lung epithelial (A549) and mouse mammary (4T1) carcinoma cells proliferation was determined by MTT assays. The cytotoxicity potency was rated as follows: NRG-NPs > NRG. The antioxidant effects of the NRG and NRG-NPs were also determined by FRAP method. Our results show that NRG-NPs are cytotoxic compounds for cancer cells and anti-cancer effect can be attributed to the presence of Fe chelatory and antioxidant effects of NRG-NPs.Â Â

Published: January 2022

Cancer is one of the malignant diseases and millions of people worldwide die from cancer annually. Breast cancer diagnosis requires the analysis of images and attributes as well as collecting many clinical and mammography variables. In diagnosis of breast cancer, it is im-portant to determine whether a tumor is benign or malignant. The information about breast cancer risk prediction along with the type of tu-mor are crucial for patients and effective medical decision making. An ideal diagnostic system could effectively distinguish between benign and malignant cells; however, such a system has not been created yet. In this study, a model is developed to improve the prediction probabil-ity of breast cancer. It is necessary to have such a prediction model as the survival probability of breast cancer is high when patients are diagnosed at early stages.Â Â

Renewable plant materials are regarded as one of the most affirmative option for the production of fuels and chemicals. With the concept of pyrolysis process, there is every possibility to produce alternative sources of energy and fuels from renewable biomass. The study depicts the production, optimization and characterization of bio-oil from pyrolyzed groundnut shell using fabricated reactor. The pyrolysis process was produced with bio-oil response, bio-char response and non condensable gases response as products. The effect of pyrolysis variables were observed by the production of the bio-oil as the response. Sixty runs of pyrolysis experiments were suggested by box Benkhen design indicated optimum pyrolysis condition at particle size of 1.15mm mesh, reaction time of 83 mins and temperature of 650oC. The maximum bio-oil yield was obtained with 33.91% at optimum condition. The bio-oil samples had better performance which met the specifications for the measured properties and compares well with the ASTM standard. Therefore, using groundnut shell for bio-oil production via pyrolysis process can serve as an approach of providing a sustainable alternative source of fuel and friendly environment.Â Â

Published: January 2022

The study Investigate the effect of carbonization temperature on properties of coconut shell. The carbonization was carried out at 600, 800, 1000 and 1150Â°C temperatures for 1 hour under inert condition. The derived chars were proximately, ultimately and structurally analyzed. The results show that there was a significant change in the volatile matter, fixed carbon percentage, elemental C and its functional group as temperature increases. The moisture content and percentage yield decrease with increasing temperature. The morphological characterization of the materials shows fibrous nature of the raw samples while the char products show developed pores which are suitable for adsorption, movement of electrolyte ions and reduced diffusion resistance. The electrical properties of char improved from 3.52 x10-8 to 6.78 x10-2 S/cm as temperature increases from 600Â°C to 1150Â°C. results from X-ray diffractometer analysis showed improved graphitic properties; which suggest a possible use of the char samples particular the PKS1150 in electrode fabrication material.Â Â
Isolation of natural caffeine from liptonâ„¢ black tea through acid-base liquid-liquid extraction approach, its medical significance and its characterization by thin layer chromatography and IR analysis
Authors: Fazal-ur-Rehman M. , Qayyum Iqra , Manzar Zahra Dr. 
Published: January 2022

To isolate the caffeine from Liptonâ„¢ Black Tea Brand, a sequence of practices was applied. An Acid-Base Liquid-Liquid Extraction approach carried out to force the caffeine to be isolated in upper organic layer as extractant. By this method, first caffeine was isolated from tea bags through passing different steps of extraction, then caffeine was isolated from tea with the use of both Solid-Liquid approach as well as liquid-liquid extraction approach. A product of 0.05 g of pure caffeine was obtained giving the percentage yield or percent recovery of 1.22%. Calculated percent recovery was 1.2 %, this percentage yield clarified that in this tea brand, very small caffeine is investigated, this deduces a significant loss of product throughout the procedure which are due to formation of emulsions and not due to washing thoroughly with DCM to extract maximum yield. It is also significant to be considered that reactions of precursor with solvent pair may not be completed, so 100% yield is not conceivable. Due to much transfers in all processes, this loss might be occurred. Due to much transfers in all processes, this loss might be occurred thatâ€™s why repeated the process three times again. It is also revealed that as much water was added which decreased the concentration of Caffeine. On analysis with IR, Peak at f=3000Hz indicates the presence of -NH2 and -CONH2 groups while the peaks at f=1600 Hz and f=1750 Hz indicates the presence of alkene portion of the caffeine molecule which concluded that Caffeine is a purine base.Â Â

Published: January 2022

The most important concern in developing countries like Pakistan is the contamination of groundwater because of the heavy metals from industrial waste which are affecting the ecosystem and public health. Some heavy metals such as Arsenic (As), Chromium (Cr), Nickel (Ni), Copper (Cu), Iron (Fe), Lead (Pb) and Zinc (Zn) are mostly reported in different cities of Pakistan and their concentrations are also to be found above the permissible levels of WHO. For domestic purposes and irrigation, groundwater is the main source in Pakistan. Its quality is getting poor because of the untreated discharge from industries. In the country, water-borne diseases are spreading quickly because of the use of unfiltered environmentally contaminated water as well as a lack of awareness of environmental laws.Â Â
