With the purpose to obtain the more useful tyrosinase assay for the monophenolase activity of tyrosinase between the spectrofluorometric and spectrophotometric continuous assays, simulated assays were made by means of numerical integration of the equations that characterize the mechanism of monophenolase activity. These assays showed that the rate of disappearance of monophenol (VssM,M) is equal to the rate of accumulation of dopachrome (VssM,DC) or to the rate of accumulation of its oxidized adduct, originated by the nucleophilic attack on o-quinone by a nucleophile such as 3-methyl-2-benzothiazolinone (MBTH), (VssM, A−ox), despite the existence of coupled reactions. It is shown that the spectrophotometric methods that use MBTH are more useful, as they do not have the restrictions of the L-tyrosine disappearance measurement method, of working at pH = 8 and not having a linear response from 100 μM of L-tyrosine. It is possible to obtain low LODM (limit of detection of the monophenolase activity) values with spectrophotometric methods. The spectrofluorimetric methods had a lower LODM than spectrophotometric methods. In the case of 4-hydroxyphenil-propionic acid, the LODM obtained by us was 0.25 U/mL. Considering the relative sensitivities of 4-hydroxyanisole, compared with 4-hydroxyphenil-propionic acid, LODM values like those obtained by fluorescent methods would be expected.

BackgroundCOVID-19 cases were first detected in the UK in January 2020 and vulnerable patients were asked to shield from March to reduce their risk of COVID-19 infection.AimTo determine the risk and determinants of COVID-19 diagnosis in shielded versus non-shielded groups, adjusted for key comorbidities not explained by shielding.Design & settingRetrospective cohort study of adults with COVID-19 infection between 1 February 2020 and 15 May 2020 in west London.MethodIndividuals diagnosed with COVID-19 were identified in SystmOne records using clinical codes. Infection risks were adjusted for sociodemographic factors, nursing home status, and comorbidities.ResultsOf 57 713 adults, 573 (1%) individuals were identified as shielded and 1074 adults had documented COVID-19 infections (1.9%). COVID-19 infection rate in the shielded group individuals compared with non-shielded adult individuals was 6.5% (n = 37/573) versus 1.8% (n = 1037/57 140), P<0.001. A multivariable fully adjusted Cox proportional hazards (CPH) regression identified that COVID-19 infection was increased with shielding status (adjusted hazard ratio [aHR] 1.52; 95% confidence interval [CI] = 1.00 to 2.30; P = 0.048). Other determinants of COVID-19 infection included nursing home residency (aHR 7.05; 95% CI = 4.22 to 11.77; P<0.001); Black African (aHR 2.52; 95% CI = 1.99 to 3.18; P<0.001), Other (aHR 1.74; 95% CI = 1.42 to 2.13; P<0.001), Non-stated (aHR 1.70; 95% CI = 1.02 to 2.84; P = 0.04), or South Asian ethnic group (aHR 1.46; 95% CI = 1.10 to 1.93; P = 0.01); history of respiratory disease (aHR 1.51; 95% CI = 1.06 to 2.16; P = 0.02); deprivation (third versus least deprived Index of Multiple Deprivation [IMD] quintile) (aHR 1.25 ; 95% CI = 1.01 to 1.56; P = 0.05); obesity (body mass index [BMI] >30 kg/m2) (aHR 1.39; 95% CI = 1.18 to 1.63; P<0.001); and age (aHR 1.02; 95% CI = 1.01 to 1.02; P<0.001. Male sex was associated with lower risk of COVID-19 infection (aHR 0.71; 95% CI = 0.62 to 0.82; P<0.001).ConclusionShielded individuals had a higher COVID-19 infection rate compared with non-shielded individuals, after adjusting for sociodemographic factors, nursing home status, and comorbidities.

Kajian ini dijalankan bagi meneroka perspektif guru berkaitan kemahiran berfikir aras tinggi (KBAT) dalam kalangan pelajar. Kajian ini menggunakan kaedah temubual separa berstruktur yang melibatkan seorang guru yang berpengalaman. Instrumen yang digunakan dalam kajian ini terdiri daripada protocol temubual dan komputer riba. Hasil kajian mendapati bahawa KBAT dalam kalangan pelajar masih perlu diperkasakan dan dipengaruhi oleh perbezaan tahap sosioekonomi dan jenis sekolah. Faktor pelajar, alat bantu mengajar, dan keadaan bilik darjah didapati mempengaruhi pemilihan strategi pengajaran bagi memupuk KBAT dalam kalangan pelajar. Hasil kajian turut mendapati bahawa teknik menyoal boleh digunakan bagi meningkatkan KBAT dalam kalangan pelajar, manakala pemberian soalan KBAT secara konsisten, penggunaan kaedah pembelajaran abad ke-21 (PAK21) dan pemberian tugasan berkumpulan boleh digunakan untuk menggalakkan aplikasi KBAT ketika pelajar menghadapi penilaian. Dapatan kajian turut menunjukkan bahawa kekangan masa dan faktor pelajar yang tidak aktif memberikan cabaran kepada guru untuk memupuk KBAT dalam kalangan pelajar. Sebagai implikasi, semua pihak perlu memainkan peranan yang sewajarnya dalam usaha meningkatkan KBAT dalam kalangan pelajar agar matlamat pendidikan dapat direalisasikan.
Teachers' Perspectives on Higher Order Thinking Skills Among Students
Abstract: This study was conducted to explore the perspectives of teachers related to high -level thinking skills (HLTS) among students. This study used a semi -structured interview method involving an experienced teacher. The instruments used in this study consisted of an interview protocol and a laptop. The results of the study found that HOTS among students still need to be empowered and influenced by differences in socioeconomic levels and types of schools. Student factors, teaching aids, and classroom conditions were found to influence the selection of teaching strategies to foster HOTS among students. The study also found that questioning techniques can be used to improve KBAT among students, while giving KBAT questions consistently, the use of 21st century learning methods (PAK21) and group assignments can be used to encourage the application of KBAT when students face assessment. The findings of the study also show that time constraints and inactive student factors provide a challenge to teachers to cultivate HOTS among students. As an implication, all parties need to play an appropriate role in efforts to improve HOTS among students so that educational goals can be realized.

METHOD OF OPTIMIZING ELEMENTS OF INTEGRATED OPTICAL AUTHENTICATION MODULE
Authors: Кулиш Ольга Александровна 
Published: August 2021

В ходе информационного обмена между локальными вычислительными сетями пользователей передаваемая информация проходит через не защищенную сеть провайдера связи. Отсутствие аутентификации коммутаторов позволяет злоумышленникам осуществлять сетевые атаки на коммутаторы второго уровня модели OSI. Для устранения проблемы аутентификации коммутационного оборудования канального уровня можно использовать модуль аутентификации, встроенный в коммутатор. В работе приведена схема интегрально-оптического интерферометра для устройства управления оптическим излучением модуля аутентификации. Так как для передачи кода аутентификации применяется ослабленное лазерное излучение, то актуальным является расчет потерь оптического сигнала в интерферометре. Высокие потери оптического излучения могут происходить во внутреннем двойном изгибе спирали и во входном и выходном разветвителях интерферометра. Разработана методика оптимизации этих элементов интерферометра для уменьшения потерь оптического сигнала. Методика основана на методе распространяющегося пучка, методе эффективного показателя преломления и конечно-элементном анализе. На основе разработанной методики можно оценить оптимальное смещение волноводов в точке перегиба внутреннего S-изгиба спирали, геометрические параметры входного и выходного разветвителей.
During information exchange between local computer networks of users, the transmitted information passes through an unprotected network of a communication provider. The lack of switch authentication allows attackers to carry out network attacks on Layer 2 switches of the OSI model. You can use the authentication module built into the switch to resolve the link layer switching equipment authentication problem. The work shows the integrated optical interferometer circuit for the optical radiation control device of the authentication module. Since attenuated laser light is used to transmit the authentication code, the calculation of optical signal losses in the interferometer is relevant. High losses of optical radiation can occur in the inner double bend of the spiral and in the input and output splitters of the interferometer. A technique has been developed to optimize these interferometer elements to reduce optical signal losses. The technique is based on the propagating beam method, the effective refractive index method, and finite element analysis. Based on the developed technique, the optimal displacement of waveguides at the inflection point of the internal S-bend of the spiral, the geometric parameters of the input and output splitters can be estimated.

Crude Sodium Di-Uranate (SDU) of Tummalapalle mine India, contains 2-3% (w/w) of silica besides 5-7% (w/w) of organic matter including polyacrylamides and humic masses with 2-5% Zirconium (Zr) (w/w) as major impurities, hence the direct conversion of SDU, to Nuclear Grade (NG) Ammonium Di-Uranate Cake (ADUC) for
fuel fabrication via HNO3-Tributyl Phosphate (TBP) extraction route is onerous due to silica gel creation, third phase inception enounces presence of excess Zr and micro-emulsion formation confirms organic matter introduces difficulties in filtration, recovery and purification stages. Various analytical techniques such as X-Ray Diffraction Analysis (XRD), Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Spectroscopy (EDS), Fourier Transform Infrared Spectroscopy (FTIR) as well as Inductively Coupled Optical Emission Spectrometer (ICP-OES) has been utilized to characterize raw material (SDU), intermediate products (gel and residues) as well as final product (NG-ADUC). In this research; an innovative, novel route for dissolution of SDU employing sulphamic acid (25% w/v) to remove silica, organic matter, and Zr followed by the conventional route to NG-ADU; eliminates the three major process difficulties viz., (i) gelation, (ii) third phase formation and (iii) microemulsion formation. In addition, sulphamic acid extracted Uranium (U)-bearing stream ultimately articulates 99.5% overall U recovery and enunciates nuclear grade U with desirable morphological characteristics.
Monisärmäinen punainen historia
Authors: Lintunen Tiina , Heimo Anne 
Published: August 2021

Tässä artikkelissa keskitymme tarkastelemaan, miten Suomen sisällissodan hävinneen puolen rooli sodassa, kokemukset ja muistaminen on huomioitu suomalaisessa yhteiskunnassa eri aikakausina. Lähestymme aihetta kolmesta näkökulmasta. Tarkastelemme ensin, miten punaiset on huomioitu historiantutkimuksessa ja kouluopetuksessa. Sen jälkeen pohdimme, miten punaisten kokemuksia on käsitelty taiteissa, kuten kirjallisuudessa, elokuvissa ja teatterissa. Kolmanneksi nostamme esiin, miten punaisia on muistettu, niin julkisesti kuin yksityisesti. Artikkelimme kannalta keskeisiä työkaluja ovat historiapolitiikan, muistin politiikan, historiakulttuurin ja historiatietoisuuden käsitteet.
Sisällissotaa koskevassa historian tuottamisessa historiapolitiikka on aina vahvasti läsnä. Joku tai jotkut päättävät, millaiset tulkinnat historiantutkimuksessa ja kulttuurissa ovat kulloinkin hyväksyttäviä. Vuoden 1918 jälkeen nämä tulkinnat olivat voittajien sanelemia, mikä on universaali ilmiö. Samoin sodan jälkeen punaisia kohtaan harjoitettiin vahvaa muistin politiikkaa. Hävinneitä ei kirjoitettu mukaan kansalliseen kertomukseen tasavertaisina kansalaisina ja myös heidän oikeuttaan harjoittaa julkista muistamista rajoitettiin. Historian käyttö oli selkeää vallan käyttöä.
Sisällissodan jälkeen sodan julkista muistamista hallitsi voittajapuoli vuosikymmenten ajan ja häviäjien oli tyydyttävä muistelemaan omia menetyksiään yksityisesti, perheen, työyhteisön tai työväenliikkeen keskuudessa. Tänä päivänä tilanne on melkeinpä kääntynyt vastakkaiseksi. Valkoisten perintöä ylläpitäviä järjestöjä ja yhdistyksiä on edelleen olemassa useita kymmeniä, mutta vaikka punaisilla ei vastaavia järjestöjä enää ole, punaisten kokemusten käsittely on näkyvämpää kuin valkoisen puolen. Sisällissodan kokeneiden sukupolvi on kuollut, mutta ylisukupolvinen muistaminen jatkuu vahvana ja näkyy eri tavoin niin taiteissa kuin muissa yhteyksissä.

De l’identité dans un monde globalisé : pour une communauté ouverte
Authors: Mesure Sylvie 
Published: August 2021

Nous vivons désormais dans un monde à la fois globalisé et culturellement différencié où les questions identitaires revêtent une importance singulière. C’est sur les différentes manières dont nous pouvons conceptualiser notre identité et nos communautés d’appartenance que sera mis l’accent dans cet article. Après avoir souligné les dangers d’une interprétation « communautarienne » de la communauté qui naturalise l’identité en la pensant comme une essence, ainsi que les apories d’une conception universaliste qui l’ouvre à l’ensemble de l’humanité sans tenir compte des identités concrètes et situées, nous plaiderons ici en faveur d’une appréhension « cosmopolite » de la communauté permettant de concevoir l’identité comme plurielle et ouverte à la différence.
