A deeply interconnected flexible transducer of polydimethylsiloxane (PDMS) and poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) was obtained as a material for the application of soft robotics. Firstly, transducers were developed by crosslinking PEDOT:PSS with 3-glycidyloxypropryl-trimethoxysilane (GPTMS) (1, 2 and 3% v/v) and using freeze-drying to obtain porous sponges. The PEDOT:PSS sponges were morphologically characterized, showing porosities mainly between 200 and 600 µm2; such surface area dimensions tend to decrease with increasing degrees of crosslinking. A stability test confirmed a good endurance for up to 28 days for the higher concentrations of the crosslinker tested. Consecutively, the sponges were electromechanically characterized, showing a repeatable and linear resistance variation by the pressure triggers within the limits of their working range (∆RR0 max = 80% for 1–2% v/v of GPTMS). The sponges containing 1% v/v of GPTMS were intertwined with a silicon elastomer to increase their elasticity and water stability. The flexible transducer obtained with this method exhibited moderately lower sensibility and repeatability than the PEDOT:PSS sponges, but the piezoresistive response remained stable under mechanical compression. Furthermore, the transducer displayed a linear behavior when stressed within the limits of its working range. Therefore, it is still valid for pressure sensing and contact detection applications. Lastly, the flexible transducer was submitted to preliminary biological tests that indicate a potential for safe, in vivo sensing applications.

Published: August 2022

BackgroundThe COVID-19 pandemic has altered the provision of health care and expanded telehealth consultations.AimTo study the effect of the COVID-19 pandemic on contact patterns in general practice, and to identify patient groups at risk of losing care.Design and settingRegister-based study of Danish general practice, including daytime and out-of-hours (OOH) services.MethodAll individuals residing in Denmark from 1 January 2017 to 31 October 2020 were included. The incidence rate for six contact types in general practice and adjusted incidence rate ratio were calculated by comparing the incidence rate in the pandemic period with the adjusted expected incidence rate based on the incidence rate in the pre-pandemic period.ResultsThe number of face-to-face in-clinic consultations declined during the lockdown in March 2020. A subsequent increase in the number of clinic consultations was observed, rising to a level above that of the pre-pandemic period; this increase resulted mainly from the introduction of telehealth consultations (that is, video and extended telephone). The number of daytime email consultations increased, whereas the number of daytime home visits decreased. Likewise, the number of OOH telephone consultations increased, whereas the number of OOH home visits and clinic consultations decreased. Consultation rates of patients who are vulnerable, that is, those with low education, old age, and comorbidity, were most adversely affected by the pandemic. The most adverse impact in OOH clinic consultations was seen for children aged 0–9 years.ConclusionNew methods are called for to ensure access to general practice for patients who are vulnerable during a pandemic. The potential of telehealth consultations should be further investigated.

BackgroundThe diagnosis of psoriasis may be missed or delayed in primary care settings.AimTo examine trends in healthcare events before a diagnosis of psoriasis.Design and settingTwo matched case–control studies using electronic healthcare records delineated from the Clinical Practice Research Datalink (CPRD GOLD and Aurum) in the UK.MethodIndividuals aged ≥18 years with an incident diagnosis of psoriasis (case group) between 1 January 2010 and 29 December 2017 were identified and matched by age, sex, and general practice with six individuals without psoriasis (control group). Healthcare activities were examined and annual incidence rates and incidence rate ratios (IRRs) with 95% confidence intervals (CIs) for 10 years before the index date were compared between case and control groups.ResultsThere were 17 320 people with psoriasis and 99 320 controls included from CPRD GOLD, and 11 442 people with psoriasis and 65 840 controls extracted from CPRD Aurum. Data from CPRD GOLD showed that people with psoriasis were up to eight times more likely to be diagnosed with pityriasis rosea at 6 months (IRR 7.82, 95% CI = 4.09 to 14.95) before the index date than the control group. The case group were twice as likely to be diagnosed with eczema (IRR 1.90, 95% CI = 1.76 to 2.05) or tinea corporis (IRR 1.99, 95% CI = 1.74 to 2.27) 1 year before the index date. The case group were more likely to report dry skin, rash, skin texture changes, and itching than the control group up to 5 years before the index date. The most frequently reported clinical feature was rash with an IRR of 2.71 (95% CI = 2.53 to 2.92) at 1 year before the index date. The case group were prescribed topical corticosteroids (IRR 1.97, 95% CI = 1.88 to 2.07) or topical antifungals (IRR 1.92, 95% CI = 1.78 to 2.07) in the year before the index date twice as often as those in the control group.ConclusionFindings suggest that the diagnosis of psoriasis may be missed or delayed in a UK primary care setting for up to 5 years for some individuals, hence leading to a potentially detrimental delay in establishing an appropriate treatment regimen.

Abstract
In this study, a CeO2-loaded In2O3 hollow sphere gas sensor for diethyl carbonate (DEC) gas detection was designed to predict the thermal runaway of Li-ion batteries. First, pure In2O3 and CeO2-loaded In2O3 hollow spheres were synthesized by a hydrothermal method. Then, the interaction mechanism between the material and DEC gas was proposed. Next, a DEC gas sensing unit was fabricated to test its gas sensing performance. In the atmosphere of 100 ppm DEC gas, it is concluded that the best working temperature of this sensor is 200 °C and the 2 at% CeO2–In2O3 sample has the largest response, which is about 5.2. The responses of all six samples increased with increasing gas concentration. The 2 at% CeO2–In2O3 sample had a response of 1.01–0.1 ppm DEC gas. The sensor also exhibits a short response-recovery time and long-term stability. This sensor holds great promise in predicting the thermal runaway of Li-ion batteries.

Authors: Machado Y. J. , Murillo-Arango W. , Hennessey-Ramos L. 
Published: August 2022

This research was aimed to evaluate the antioxidant capacity, the phenolic content, the dye stability, the yield of extracts of different polarities obtained from the peel of mangosteen (Garcinia Mangostana), and finally, their potential use as an additive in mangosteen fruit beverage. Water, ethanol, and different mixtures were used to obtain the dye extracts. Physicochemical and microbiological stability was measured according to Colombian Resolution 3929 of 2013 to determine whether the beverage complies with current regulations. CIE L*a*b* scale measured the color stability of the beverage for 30 days, the sensorial acceptance with a hedonic scale. The best extraction performance was achieved with the mixture of water and ethanol in a 1:1 ratio, yielding 23.07 ±0.12% of total biomass extracted from the peel, and the phenolic content was 368.7 mg GAE 100 mL-1, IC50 values of 184 mg mL-1, and 146 mg mL-1 by the ABTS and DPPH respectively. The beverage prepared from mangosteen pulp and dye extract reached the microbiological requirements by Resolution 3929 of 2013 for fruit drinks. The sensorial test showed that formulated mangosteen beverage dye extract is hedonically the same at treatment with ascorbic acid.

Towards Steering Magnetic Nanoparticles in Drug Targeting Using a Linear Halbach Array
Authors: Thalmayer Angelika , Zeising Samuel , Lübke Maximilian , Fischer Georg 
Published: August 2022

<p>Magnetic nanoparticles offer numerous promising biomedical applications, e. g. magnetic drug targeting. Here, magnetic drug carriers inside the human body are directed towards tumorous tissue by an external magnetic field. However, the success of the treatment strongly depends on the amount of drug carriers, reaching the desired tumor region. This steering process is still an open research topic. In this paper, the previous study of a linear Halbach array is extended by an additional Halbach array with different magnetization angles between two adjacent magnets and investigated numerically using COMSOL Multiphysics. The Halbach arrays are arranged with permanent magnets and generate a relatively large region of a moderately homogeneous, high magnetic field while having a strong gradient. This results in a strong magnetic force, trapping many particles at the magnets. Afterwards, to avoid particle agglomeration, the Halbach array is flipped to its weak side. Therefore, the magnetic flux density, its gradient and the resulting magnetic force are computed for the different Halbach arrays with different constellations of magnetization directions. Since the calculation of the gradient can lead to high errors due to the used mesh in Comsol, the gradient was derived analytically by investigating two different fitting functions. Overall, the array with a 90° shifted magnetization performs best, changing the magnetic sides of the array easily and deflecting more particles. Besides, the results revealed that the magnetic force dominates directly underneath the magnets compared to the other existing forces on the SPIONS. Summarized, the results depict that the magnetic force and, thus, the region where the particles are able to get washed out, can be adjusted using low-cost permanent magnets. <br>

Direct Synthesis of Far-Field Patterns
Authors: Xiao Gaobiao 
Published: August 2022

<p>I believe that the direct synthesis results must be a very good base for further optimizing the patterns. Following my intuition and my experience in synthesizing nonuniform transmission lines 20 yrs ago, I managed to develop a hybrid optimization algorithm. It seems to work well, so I managed to discuss it in a paper for reference, again as a part of my effort of revisiting the electromagnetic radiation issue.</p>
<p><br></p>
<p>I feel sorry that the manuscript is written in a hurry and most content of the synthesis of the linear arrays is similar to that discussed in C.A. Balanis book as pointed out by reviewers. However, I still post this manuscript on this server as I indeed derived it from the very beginning and I wish some part of them may be of useage for others, especially the 2-D cases and some of my considerations on this issue. I have searched journal papers but not books before I began to write this issue. I should have to. </p>
<p><br></p>
<p>In this paper, the current distribution is expanded with Fourier series. Analysis shows that only a limited number of the harmonic components of the current can generate propagation fields and contribute to the far-field pattern. Most importantly, it is found that this part of the current can be directly obtained from the far-field without utilizing any optimization algorithm. The degree of freedom of the far-field can be exactly counted for a linear source or a rectangular planar source. Numerical examples verify that the method is very efficient for synthesizing large antenna arrays. </p>
A Survey on Radar Techniques for Detection,Tracking, and Classification of Aerial Threats
Authors: Khawaja Wahab Ali Gulzar 
Published: August 2022

<p> The use of unmanned aerial vehicles (UAVs) for different applications has increased many folds in recent years. The UAVs are expected to change the future air operations. However, there are instances where the UAVs can be used for malicious purposes. The detection, tracking, and classification of UAVs is challenging compared to manned aerial vehicles (MAVs) mainly due to small size, complex shapes, and ability to fly close to the terrain and in autonomous flight patterns in swarms. In this survey, we will discuss current and future aerial threats, and provide an overview of radar systems to counter such threats. We also study the performance parameters of radar systems for the detection, tracking, and classification of UAVs compared to MAVs. Finally, limitations of radar systems and comparison with other techniques that do not rely on radars for detection, tracking, and classification of aerial threats are also provided. </p>
أدلة الإثبات الجنائي في القضاء الجنائي الدولي (دراسة تحليلية)

Published: August 2022

إذا كانت الدعوى الجنائية في التشريعات الوطنية تطرح على المحكمة – خاصة في الجنايات- بعد التحقيق فيها بمعرفة إحدى سلطات التحقيق، وتقوم المحكمة بتحقيق الأدلة المطروحة عليها من جديد بنفسها، حتى تتمكن من تمحيصها بهدف تكوين عقيدتها لتصدر حكمها بعد ذلك بالإدانة أو بالبراءة، فإن الوضع بالنسبة للمحاكم الجنائية الدولية لا يبعد كثيرًا عن الوضع بالنسبة للمحاكم الوطنية؛ حيث إن النظام الأساسي لهذه المحاكم نظّم أدلة الإثبات خاصة فيما يتعلق بالاعتراف، وشهادة الشهود. وقبل أن نعرض للشهادة والاعتراف بالذنب، ينبغي أن نبيّن أن من الأمور المهمة عند دراسة أي نظام قضائي، هو معرفة القواعد العامة للإثبات، إذ هي المحور الذي تدور حوله إجراءات المحاكمة. والجدير بالملاحظة أن الأنظمة الأساسية للمحاكم الجنائية الدولية اختلفت في تبنّيها لمثل تلك القواعد، فالنظام الأساسي لمحكمة نورمبرغ لم ينص على تلك القواعد، وكذلك الحال بالنسبة لمحكمة طوكيو إذ إن القواعد الإجرائية وقواعد الإثبات التي سارت عليها المحكمة تم اعتمادها لاحقاً من قضاة المحكمة، وقد سارا على نفس النهج النظامين الأساسين لكلٍ من محكمتي يوغسلافية السابقة ورواندا.
أما بالنسبة للنظام الأساسي للمحكمة الجنائية الدولية، لم يتضمن سوى بعض أهم الجوانب الأساسية للإثبات، أما بقية الأمور فقد تضمنتها القواعد الإجرائية وقواعد الإثبات التي تميزت عن سابقاتها بأنها قد تمت صياغتها من "اللجنة التحضيرية للمحكمة الجنائية الدولية".

Authors: منجد منال 
Published: August 2022

يعد تحويل الجنس من الظواهر التي انتشرت بصورة لافتة في السنوات الأخيرة، وقد بدأ تحويل الجنس في الدول الأجنبية كنوع من أنواع العلاج الطبي للحالات التي تقتضي ذلك، إلا أن النظرة فيما بعد قد تغيرت وأصبح حق الإنسان في تحويل جنسه واختيار نوعه من حقوق الإنسان الأساسية التي ينادي بها الغرب، والتي تنظمها التشريعات الأجنبية ضمن إجراءات قانونية تختلف من دولة إلى أخرى.
ولأن العالم بعد انتشار الانترنت ووسائل التواصل الاجتماعي قد تحول إلى قرية صغيرة، فقد بدأت هذه الظاهرة تغزو المجتمعات العربية، وكان لابد للمشرع في دولة الإمارات العربية المتحدة من بيان موقفه من هذه الظاهرة الخطيرة، حيث نظم مسألة تحويل الجنس بالمرسوم بقانون رقم/4/ لعام 2016 المتعلق بالمسؤولية الطبية و ميّز بين تغيير الجنس الذي عده جريمة يعاقب عليها بعقوبة جنائية الوصف وتصحيح الجنس الذي عده عملاً مباحاً.
يتناول هذا البحث بالتحليل والمناقشة مسألة التنظيم القانوني لعمليات تحويل الجنس في دولة الإمارات العربية المتحدة، ولغرض ذلك فقد قسمنا بحثنا إلى مبحثين، تعرضنا في المبحث الأول لماهية عمليات تحويل الجنس، في حين تناولنا في المبحث الثاني الاتجاهات القانونية والشرعية المتباينة من مسألة تحويل الجنس وخلصنا إلى بعض النتائج والتوصيات.

Published: August 2022

يتناول هذا البحث مناقشة مشروعية ممارسة أنشطة الفضاء الخارجي، ولأن لجميع دول العالم الحرية في استكشاف واستخدام الفضاء الخارجي، بما في ذلك القمر والأجرام السماوية الأخرى دون تمييز وعلى قدم المساواة وفقا للقانون الدولي؛ فقد ينتج عن هذه الحرية بعض الاستخدامات غير المشروعة كالتجارب النووية أو تجارب بيولوجية تؤدي الى الإضرار بالفضاء الخارجي وهذه هي مشكلة البحث. وكان التساؤل الرئيسي هو ما مدى مشروعية استخدام الفضاء الخارجي على سطح القمر.
وتوصلت الدراسة الى عدد من النتائج كان أهمها أن جميع الدول لها حرية الاستكشاف والاستخدام السلمي للفضاء الخارجي، وعدم وجود سلطة تنفيذية دولية لتنفيذ قرارات لجنة تسوية المطالبات ومن خلالها يتم إجبار الدول المطلقة على تعويض الدولة المتضررة، وعدم وجود هيئة دولية تخضع لسلطاتها الأجسام الفضائية الموجودة في الفضاء الخارجي والاكتفاء بخضوعها الى الدول المطلقة.
