A SHORT-TERM REVIEW ON SOLID LIPID NANOPARTICLES
Authors: S MOHANRAJ , B JAYANTHI
Published: May 2022

In recent years, Solid lipid nanoparticles (SLNs) have been given a lot of attention as a potential drug distribution alternative to existing colloidal dispersion technologies. The use of SLNs as a pharmaceutical carrier has gotten a lot of focus in recent years. Nanostructure lipid carriers and SLNs are non-toxic since they are biodegradable. SLNs have various distinct properties in terms of therapeutic uses. SLNs are lipid-based nanocarriers with sizes ranging between 10 to 1000 nanometers. Decomposition of the drug can be protected by the drug entrapped in a lipid, physical stability; controlled drug release and remarkable acceptability are all benefits of SLNs over traditional drug carriers. The capacity to incorporate pharmaceuticals into nanocarriers opens up a new paradigm in drug delivery that could hold enormous promise in terms of improving bioavailability while also allowing for controlled and site-specific drug delivery. This article covers the manufacture and characterization of SLNs, as well as the administration and medicinal uses.

Published: May 2022

This study aimed at exploring the Access to Covid-19 Health Information among the Deaf Community in Ghana. The study employed randomly selected 40 Junior High School respondents from the designated deaf schools in the Northern Region of Ghana. The study is an exploratory research with cross-sectional survey as its main design. The instruments for data collection was mainly questionnaire administered manually and through electronic medium (Google forms), interviews and focus group discussions were also conducted over a certain period of time. The data was analysed in SPSS and Pearson Moment Correlation. Access to information is vital during this pandemic, the study however revealed that there is adequate Covid-19 information available for the deaf, and the major bottleneck is dissemination since there is no universally recognized sign language for Covid-19 information. The affected group has to endure this difficulty which often resulted into infection and even death. Covid-19 management and aid with fair health care navigation approaches should be provided to the deaf community. The health-care system owes it to deaf patients to assist them in obtaining primary health-care services. To assist communicate health information online, public health professionals should ensure that public service announcements are accessible and widely distributed through deaf community trust agents. It is determined that greater efforts should be made to ameliorate the perceptions of the Covid-19 pandemic that is devouring the world through educational campaigns and information dissemination through various media to a larger deaf population.
ИРОНИЯТА И АМБИВАЛЕНТНОСТТА КАТО ЕЗИКОВО¬СПЕЦИФИЧНИ МЕХАНИЗМИ ЗА КОДИРАНЕ НА ЗНАЧЕНИЕ / IRONY AND AMBIVALENCE AS LANGUAGE-SPECIFIC MEANING
CODING MECHANISMS
Authors: STAMENOV MAXIM
Published: May 2022

The article offers an analysis of the similarities and differences between irony and ambivalence. The two phenomena share the ability to be expressed in linguistic form;
both of them most often rely on the oscillation between a positive and a negative meaning of a single word or expression. The difference between them is that virtually any word denoting a positive characteristic of a person can be used ironically, given that irony is contextually conditioned. No matter how often we use genius in the sense of mediocre or stupid, the ironic use will not evolve into a distinct sense of the polysemous word genius. Unlike irony, ambivalent meanings do not depend on the context of use in the same way and should be encoded in the dictionary. Thus, Bulgarian келеш “squirt; fop” is defined in the Dictionary of the Bulgarian Language (RBE 1977–) as “2. coll. contempt. usually as a form of address. A boy or a young man who is or seems to be inexperienced, unfit for something, but who is self-confident, arrogant, daring or wayward, headstrong. 3. rarely, iron. Used about a resourceful, deft, capable young man”. However, it is inaccurate to define these two senses as “contemptuous” and “ironic”. The first one is ambivalent and may hence imply contempt or ridicule, where-as the second one is, as the analysis shows, admiratively ambivalent and can express attitudes ranging from astonishment to envy resulting from prior underestimation of the qualities of the individual in question.
Keywords: irony, ambivalence, ways of coding interpersonal evaluation or attitude using linguistic means

Published: May 2022

The crucial prerequisite in these days is to get rid of various forms of attacks. Nowadays, for financial transaction, automated teller machines (ATMs) are the mostly used gadgets in which personal identification numbers (PINs) are generally used for transaction. But personal identification numbers (PINs) are not secured from many types of threats (spoofing, eavesdropping, man-in-the middle attack etc.), which can affect the security of the confidential and private information. Due to this reason, different biometric systems gain popularity worldwide for their behavioral and physiological features. However, the current biometric systems, for example, iris, palm, faces or voice are extremely complex to use and have different disadvantages. In order to overcome these disadvantages a new concept has been introduced in this paper, for authentication in ATM a fingerprint authentication method and for information (finger print) transfer a combined approach fingerprint and RF technology scheme is used. Finger authentication system is implemented by the combination of fingerprint reader and fingerprint sensors. For the purpose of information (fingerprint) scanners work by capturing the pattern of ridges and valleys on a finger. The information is then scanners work by the device’s pattern analysis. For fingerprint authentication system, the experiment shows that in proposed classification the average recognition accuracy is 99.75% and 99.92 % and the execution time is 0.168 s and 0.187 s respectively..

Published: May 2022

The time, quality, and cost are three important but contradictive objectives in a building construction project. It is a tough challenge for project managers to optimize them since they are different parameters. Tradeoffs between project duration, total cost, quality and risk are extensively discussed in the project scheduling. This paper tries to develop a Time, Cost and Quality optimization model that enables managers to optimize multi objectives. The model is from the project break down structure method where task resources in a construction project are divided in to series of activities and further in to construction labors, materials, equipment and administration. Quality is an important parameter correlating highly with time and cost parameters .But it is not a quantitative in nature , practical time cost , quality tradeoff models are seldom developed from previous research works of the literature. Although the objectives of cost and time must be mentioned frequently by natural numbers. This paper will present a new solution for solving time, cost, and quality tradeoff problem based on project break down structure method and task resource allocation. The resource utilized in a construction activity would eventually determine its construction time, cost, quality tradeoff model is finally generated based on correlations between construction activities.

The relative effect of upper cervical spine manipulation, placebo and a control, on neck muscle activity, pain and disability in participants with cervicogenic headache
Authors:   , Brann William Edward
Published: May 2022

Objectives: Cervical spinal manipulation (CSM) has been shown to be effective in treating cervicogenic headache (CGH) by reducing pain and disability. There is a paucity of research investigating whether changes in muscle activity account for the changes in patient reported outcomes in patients with CGH following CSM. The aim of this study was to determine the effect of upper CSM compared to a placebo and a control intervention in terms of subjective (pain and disability rating) and objective measures (muscle activity and force output of the trapezius, posterior cervical and sternocleidomastoid muscles) in the treatment of CGH. Methods: A randomized, controlled, pre-test, post-test, experimental design allowed for 45 participants, aged 18-50, with CGH to be allocated to a CSM, placebo or control group. Pain and disability were measured before and telephonically 48 hours after the intervention. Muscle activity and force output of the trapezius, posterior cervical and sternocleidomastoid (SCM) muscles were measured before and immediately after the intervention. IBM SPSS was used to analyse the data with significance set at p=0.05. The subjective and objective measures were not normally distributed and this resulted in nonparametric statistical tests being utilised to analyse the data. Wilcoxon Signed Rank Tests were used to determine significance within groups and Independent-samples KruskalWallis Tests and Pairwise multiple comparison tests were used to determine significance between groups. Results: No significant differences were found between the three groups for age (p=0.460) and gender (p=0.566), with a marginally significant finding for race (p=0.046). Subjective measure assessment found only a significant decrease in pain (p=0.001) and disability (p=0.001) from pre- post-test within the CSM group. Intergroup analysis found that the CSM group experienced the greatest reduction in pain (p=0.001) and disability (p=0.001) when compared to the placebo and control groups. Clinically, only pain in the CSM group decreased significantly. Objective findings showed significant intragroup increases in muscle activity, found bilaterally in the SCM (p=0.017 SCMR) (p=0.012 SCML) and trapezius muscles (p=0.041 TrapR) (p=0.041 TrapL) in the CSM group and only in the trapezius muscle (p=0.031 TrapR) (p=0.027 TrapL) bilaterally in the placebo group. Force output only increased in the trapezius muscle on the left (p=0.027) in the placebo group and bilaterally in the control group (p=0.031 TrapR) (p=0.041 TrapL) There were no significant intergroup differences between the groups for muscle activity and force output in the trapezius, posterior cervicals and SCM

Published: May 2022

В данной статье представлен метод, направленный на решение проблемы раннего обнаружения возгорания на видеоизображениях с камер наблюдения, основанный на временном анализе подозрительной области. Представленный метод позволяет проводить сжатие рассматриваемой области видеоизображения до временного ряда, который классифицируется рекуррентной нейросетью. Временной ряд собирается из метрик, снимаемых с самой области и окружения, которые отражают ее «мерцание». Анализ «мерцания» позволяет определить, содержит ли область огонь. Предложенный алгоритм позволяет значительно снизить количество ложных срабатываний при обнаружении огня благодаря анализу видеоизображения по времени. Способ сжатия исходных данных до временного ряда из набора характеристик области и окружения позволяет использовать небольшую рекуррентную нейросеть для классификации подозрительной области вне зависимости от ее размера. Эти особенности позволяют применить данную модель при создании автономного детектора для раннего обнаружения возгорания на основе одноплатного компьютера и видеокамеры. В статье приводится описание предложенной модели и обучения нейросети, оценки качества обучения и результаты экспериментов, а также примеры работы, выполненные на одноплатном компьютере Jetson Nano от NVIDIA. 

This article presents a method for early fire detection using video images from surveillance cameras, based on a temporal analysis of the suspicious area. The method makes it possible to compress the area of the video image to a time series, which is classified by a recurrent neural network. The time series contains metrics measured in the area and its surroundings to consider for its flicker. The flicker analysis determines whether the area is on fire. The proposed algorithm significantly reduces the number of false fire alarms as the video image are analyzed over time. The source data compression to a time series containing the area and surrounding characteristics allows using a small recurrent neural network to classify a suspicious area regardless of its size. These features make this model applicable for building an autonomous fire detector based on a single-board computer and a video camera. The paper describes the proposed model and the neural network training, training quality evaluation and the results of experiments, as well the results generated with the Jetson Nano single-board computer from NVIDIA.

Progressive course of lower extremity arterial disease (LEAD) leads to intermittent claudication, critical ischemia and gangrene for which amputations are performed. Revascularizing surgeries help avoid limb loss, but the results are not satisfactory. Amino acids have different effects on the development and course of atherosclerosis, so some of them can be considered as predictors of postoperative complications in patients with LEAD. Objective: to analyze the effect of revascularization surgeries on amino acid pool indexes among patients with LEAD and to determine their correlation with the rate of postoperative complications. Materials and methods: 133 patients with LEAD were examined. The age of the examined patients was 63 [57; 68] years. All the patients suffered from chronic arterial insufficiency. The levels of amino acids and their derivatives were determined by high-performance liquid chromatography. Results and discussion: After revascularization there were statistically significant changes in the values of the following amino acids: Hsu, gGluCys, Asn, Gln, His, 1MHis, HpTau, Tau, Tyr, aABA, Val, Met, Trp, Ile, Leu, Lys, Pro. The patient follow-up period was 20 [12; 26] months. During this observation period, 31 complications were revealed. We identified the most significant amino acids influencing the development of postoperative complications: Hcy, CysGly, PSer, 3MHis, 1MHis and HPro. Hcy, CysGly, and 1MHis appeared to be the most powerful predictors. Using these predictors, a prognostic model was developed with a sensitivity of 74.19%, specificity of 74.51%, and accuracy of 74.44%. Conclusions: Successfully performed revascularization, by eliminating ischemia, is able to affect amino acid pool values. Hsu, CysGly and 1MHis are the most reliable predictors of postvascularization complications among the patients with LEAD.

Authors:   Belarusian State Medical University, V.V. Strogij
Published: May 2022

The article presents data on the structure, frequency of occurrence of some rare forms of supraventricular tachycardia in childhood, highlighting the clinical and electrophysiological variant of rhythm disturbance to determine the nature of further treatment and follow-up. Of the 1124 children who applied for tachycardia, 194 children were selected, who underwent an in-depth study of the properties of the conduction system of the heart by performing a transesophageal electrophysiological study. The structure of supraventricular tachycardia was established with the following: atrioventricular reciprocal tachycardia, atrioventricular nodal reciprocal tachycardia, focal atrial tachycardia and atrial fibrillation/flutter. The relatively rare detection of concomitant pathology in children with SVT (11.8%) emphasizes the need for a detailed collection of cardiac history, clinical and laboratory examination at the previous stages of medical care.

Abstract. Soot, or black carbon (BC), aerosol is a major climate forcer with severe health effects. The impacts depend strongly on particle number concentration, size and mixing state. This work reports on two field campaigns at nearby urban and rural sites, 65 km apart, in southern Sweden during late summer 2018. BC was measured using a single particle soot photometer (SP2) and Aethalometers (AE33). Differences in BC concentrations between the sites are driven primarily by local traffic emissions. Equivalent and refractory BC mass concentrations at the urban site were on average a factor 2.2 and 2.5 higher than at the rural site. Peaks in rush hour BC mass concentrations at the urban site were up to a factor ~4 higher than the background levels. The number fraction of particles containing a soot core was significantly higher in the city. BC particles at the urban site were on average smaller by mass and had less coating owing to fresh traffic emissions. The organic components of the fresh plumes were similar in mass spectral signature to “hydrocarbon-like organic aerosol” (HOA), commonly associated with traffic. Despite the intense local traffic (~30 000 vehicles passing per day), PM1, including organic aerosol, was dominated by aged continental air masses even at the curbside site. The fraction of thickly coated particles at the urban site was highly correlated with the mass concentrations of all measured chemical species of PM1, consistent with aged, internally mixed aerosol. Trajectory analysis for the whole year showed that air masses arriving at the rural site from eastern Europe contained approximately double the amount of BC compared to air masses from western Europe. Furthermore, BC from the largest region emissions in the Malmö/Copenhagen urban area transported to the rural site is discernable above background levels only when precipitation events are excluded.
Technique for comparison of backscatter coefficients derived from in-situ cloud probe measurements with concurrent airborne Lidar

Published: May 2022

Abstract. Jet engine power loss due to ice particle accumulation is a recognized aviation hazard occurring in cloud conditions difficult to forecast or visually recognize. High-altitude cirrus clouds can have ice particle concentrations high enough to be dangerous; therefore, pilots must be informed when aircraft enter such environments. One approach to determining ice particle concentration is an onboard Lidar system. Concurrent Lidar measurements are compared to backscatter coefficients derived from particle size distributions obtained from wing-mounted, in-situ probes during four case studies consisting of sixty-second flight segments at different temperatures; +7 °C and +4 °C for water droplet analysis, -33 °C and -46 °C for ice particle analysis. Backscatter coefficients derived from external cloud probes (ECP) are correlated (0.91) with measurements by an airborne Lidar system known as the Optical Ice Detector (OID). Differences between OID and ECP backscatter coefficients range from less than 1 to over 3 standard deviations uncertainties. The backscatter coefficients are primarily in agreement for liquid clouds and disagreement for the -33 °C and -46 °C cases, with ECP derived backscatter coefficients lower than the OID for three out of the four cases. Measurements over four research flights show that measured total water content is correlated (0.74) with the OID backscatter coefficient, which indicates that the OID is a useful instrument for determining ice particle concentrations over a broad range of environments, including at ice water contents as low as 0.02 g m-3. Additionally, concurrent measurements from cloud imaging probes and an airborne Lidar test system provides improved knowledge of cloud conditions and can help in understanding cloud processes.
Thermal regime of the Grigoriev ice cap and the Sary-Tor glacier in the Inner Tien Shan, Kyrgyzstan
Authors: Van Tricht Lander , Huybrechts Philippe
Published: May 2022

Abstract. The thermal regime of glaciers and ice caps represents the internal distribution of ice temperatures. Accurate knowledge of the thermal regime is important to understand the dynamics and response of ice masses to climate change, and to model their evolution. Although the assumption is that most ice masses in the Tien Shan are polythermal, this has not been examined in appropriate detail so far. In this research, we investigate the thermal regime of the Grigoriev ice cap and the Sary-Tor glacier, both located in the Inner Tien Shan in Kyrgyzstan, using a 3D higher-order thermomechanical ice flow model. Input data and boundary conditions are inferred from a surface energy mass balance model, a historical air temperature and precipitation series, ice thickness measurements and reconstructions, and digital elevation models. Calibration and validation of the englacial temperatures is performed using historical borehole measurements on the Grigoriev ice cap and radar measurements for the Sary-Tor glacier. The results of this study reveal a polythermal structure of the Sary-Tor glacier and a cold structure of the Grigoriev ice cap. The difference is related to the larger amount of snow (insulation) and superimposed ice (release of latent heat) for the Sary-Tor glacier resulting in higher ice surface temperatures, especially in the accumulation area, which are subsequently advected downstream. Further, ice velocities are much lower for the Grigoriev ice cap with consequent lower horizontal advection rates. A detailed analysis concerning the influence of temperature and precipitation changes at the surface reveals that the thermal structure of both ice bodies is not a constant over time, with recent climate change causing more temperate ice in higher areas. The selected ice masses are representative examples of the (Inner) Tien Shan glaciers and ice caps. Therefore, our findings and the calibrated parameters can be generalised allowing to improve the understanding of the dynamics and future evolution of other glaciers and ice caps in the region.
Luminescence age calculation through Bayesian convolution of equivalent dose and dose-rate distributions: the De_Dr model
Authors: Mercier Norbert , Galharret Jean-Michel , Tribolo Chantal , Kreutzer Sebastian , Philippe Anne
Published: May 2022

Abstract. In nature, each mineral grain (quartz or feldspar) receives a dose rate (Dr) specific to its environment. The dose-rate distribution therefore reflects the micro-dosimetric context of grains of similar size. If all the grains were well bleached at deposition, this distribution is assumed to correspond, within uncertainties, with the distribution of equivalent doses (De). The combination of the De and Dr distributions in the De_Dr model proposed here
would then allow calculation of the true depositional age. If grains whose
De values are not representative of this age (hereafter called
“outliers”) are present in the De distribution, this model allows them to be identified before the age is calculated, enabling their exclusion. As the De_Dr approach relies only on the Dr distribution to describe the De distribution, the model avoids any assumption about the shape of the De distribution, which can be difficult to justify. Herein, we outline the mathematical concepts of the De_Dr approach (more details are given in Galharret
et al., 2021) and the exploitation of this Bayesian modelling based on an R
code available in the R package “Luminescence”. We also present a series of tests using simulated Dr and De distributions with and without outliers and show that the De_Dr approach can be an alternative to available models for interpreting De distributions.
