Implicit A-Stable Peer Triplets for ODE Constrained Optimal Control Problems
Authors: Lang Jens , Schmitt Bernhard A. 
Published: August 2022

This paper is concerned with the construction and convergence analysis of novel implicit Peer triplets of two-step nature with four stages for nonlinear ODE constrained optimal control problems. We combine the property of superconvergence of some standard Peer method for inner grid points with carefully designed starting and end methods to achieve order four for the state variables and order three for the adjoint variables in a first-discretize-then-optimize approach together with A-stability. The notion triplets emphasize that these three different Peer methods have to satisfy additional matching conditions. Four such Peer triplets of practical interest are constructed. In addition, as a benchmark method, the well-known backward differentiation formula BDF4, which is only A(73.35∘)-stable, is extended to a special Peer triplet to supply an adjoint consistent method of higher order and BDF type with equidistant nodes. Within the class of Peer triplets, we found a diagonally implicit A(84∘)-stable method with nodes symmetric in [0, 1] to a common center that performs equally well. Numerical tests with four well established optimal control problems confirm the theoretical findings also concerning A-stability.

Published: August 2022

BackgroundAmbulatory blood-pressure monitoring (ABPM) has become less frequent in primary care since the COVID-19 pandemic, with home blood-pressure monitoring (HBPM) often the preferred alternative; however, HBPM cannot measure night-time blood pressure (BP), and patients whose night-time BP does not dip, or rises (reverse dipping), have poorer cardiovascular outcomes.AimTo investigate the importance of measuring night-time BP when assessing individuals for hypertension.Design and settingRetrospective cohort study of two patient populations — namely, hospital patients admitted to four UK acute hospitals located in Oxfordshire, and participants of the BP in different ethnic groups (BP-Eth) study, who were recruited from 28 UK general practices in the West Midlands.MethodUsing BP data collected for the two cohorts, three systolic BP phenotypes (dipper, non-dipper, and reverse dipper) were studied.ResultsAmong the hospital cohort, 48.9% (n= 10 610/21 716) patients were ‘reverse dippers’, with an average day–night systolic BP difference of +8.0 mmHg. Among the community (BP-Eth) cohort, 10.8% (n= 63/585) of patients were reverse dippers, with an average day–night systolic BP difference of +8.5 mmHg. Non-dipper and reverse-dipper phenotypes both had lower daytime systolic BP and higher night-time systolic BP than the dipper phenotype. Average daytime systolic BP was lowest in the reverse-dipping phenotype (this was 6.5 mmHg and 6.8 mmHg lower than for the dipper phenotype in the hospital and community cohorts, respectively), thereby placing them at risk of undiagnosed, or masked, hypertension.ConclusionNot measuring night-time BP puts all groups, other than dippers, at risk of failure to identify hypertension. As a result of this study, it is recommended that GPs should offer ABPM to all patients aged ≥60 years as a minimum when assessing for hypertension.

Published: August 2022

This research was designed to know the effect of different estrus synchronization protocols on Serum E, P, FSH, and LH during different estrus periods and pregnancy in Karadi and Arabi ewes. The study was carried out by using 30 ewes for each breed at 2-4 years. Ewes from each breed were equally and randomly distributed into three groups. The first group was treated with vaginal sponges saturated with (60 mg) of Medroxy progesterone acetate within a period of (14) fourteen days (T1). The second group was administrated with the MAP injected with a dose of 300 IU / head of the hCG (T2). The third group was treated with MAP treatment, and injected at a dose of 75 µg /head of GnRH (T3). The results of this analysis showed a significant increase in the estrogen concentration in the different reproductive stages; the significant level of estrogen in the estrus phase (60.96) pg/ml. The concentration of progesterone differed significantly in the different reproductive stages, with the highest concentration in the pregnancy period (16.33) pg/ml. In comparison, the FSH concentration differed significantly in the different reproductive stages with the highest concentration in the estrus period(3.243) mIU/ml. the highest significant level of serum LH is in the estrus period (5.230) mIU/ml. Thus, the study is concluded that hormones and phases may be effective in inducing follicular growth and ovulation and finally may increase pregnancy rate and production .

Published: August 2022

تهدف هذه الدراسة إلى بيان فاعلية قواعد تنازع القوانين في حماية المستهلك في تعاملاته الدولية الخاصة في ظل التشريع البحريني مقارنةً بالتنظيمات الأوروبية التي صدرت في هذا الخصوص.
لا يخفى أن العقود الدولية التي يبرمها المستهلك مع أشخاص آخرين من خارج الدولة التي فيها مقر إقامته المعتادة، قد تخضعه لقوانين لا يكون على علم أو اطلاع بتفاصيلها؛ وليس هذا فحسب بل أصبح بإمكان المنتج أو المزود المتعاقد مع المستهلك، وفقا لمبدأ حرية الإرادة المستقر ضمن قواعد تنازع القوانين، اختيار قانون أجنبي معين ليكون القانون الواجب التطبيق على العقد كذريعة للتهرب من تطبيق القواعد الآمرة الخاصة بحماية المستهلك في دولة هذا الأخير؛ وكل هذا يحدث بسبب التفاوت في القوة التفاوضية والاقتصادية بين أطراف العقد: المستهلك وهو الطرف الضعيف في مقابل طرف آخر أقوى وهو المهني المحترف ويسمى أيضا بالمزود.
خلصت الدراسة إلى غياب التشريعات التي توفر الحماية الكافية اللازمة للمستهلك خارج حدود دولته، وتوصي بذلك بضرورة توفير حماية إجرائية للمستهلك ضمن قواعد تنازع القوانين لضمان تطبيق القواعد الوطنية الآمرة في قانون الدولة التي يقيم فيها المستهلك وبالنتيجة لضمان حقه في التقاضي.
Insider Dealing in Kuwait: A comparative study with United Kingdom and the United States
Authors: Al-Shebli Abdullah 
Published: August 2022

Insider dealing involves the use of information that is not disclosed to the public. Insider dealing has a long and controversial history with regard to securities laws, because some people believe that insider dealing should not be banned by law. However, nearly every country bans insider dealing, although it is done in different ways. This article considers insider dealing as an example of fraud on the stock exchange. It examines protection of individual investors form insider dealing under the Kuwait Capital Markets Act of 2010 (the Act) and suggests recommendations that have the potential to provide more protection to such investors. In order to achieve this aim, this article discusses the existing legal framework for the regulation of insider dealing in the Kuwait and the UK stock markets. It also looks at American law, because the United States has a long history and extensive experience in this regard.

Introducción: El Síndrome Post-COVID-19 ha sido la terminología mas acuñada para el diagnóstico de las secuelas que persisten por más de 3 meses posterior a la infección por el virus SARS-CoV-2. Objetivo: Determinar la prevalencia del Diagnóstico Post-COVID-19. Metodología: Estudio descriptivo, transversal, retrospectivo y observacional. El universo consiste en todos los pacientes mayores de edad hospitalizados que ameritaron oxigenoterapia en el Centro Integral de Atención Provisional para Pacientes Moderados COVID-19 (FIGALI) durante el primer trimestre de 2021. Se describen los datos demográficos, las comorbilidades, los principales síntomas persistentes y la asistencia a Clínicas Post-COVI
Resultados: Predominaron los mayores a 50 años (66%), con una estadía promedio de 10 días, ameritando la mayoría (79%) oxigenoterapia de bajo flujo (COVID-19 moderado), con distribución equitativa del sexo y mayoría de los encuestados tenía un mínimo de 5 meses de egresados. Las principales comorbilidades reportados fueron la hipertensión arterial (57%) y la diabetes mellitus (31%). La prevalencia del Diagnóstico Post-COVID-19 fue de 74% (131/177), siendo la fatiga, la tos y la disnea los principales síntomas reportados (45%, 32%, 29%) respectivamente. En el aspecto neuro-psiquiátrico se evidencia la ansiedad con un 18% y la depresión en 14% de los pacientes encuestados. Conclusiones: tres de cada cuatro pacientes que ameritaron oxigenoterapia, han persistido con al menos 1 síntoma luego de más de 5 meses de haber estado hospitalizado, siendo la fatiga el predominante. A pesar de la alta prevalencia descrita en este estudio, tan solo uno de cada cuatro pacientes, reporta haber acudido a Clínicas Post-COVID.
Trabajo en equipo en el quehacer científico en nuestra región
Authors: Cuero Cesar 
Published: August 2022

El grupo de las llamadas enfermedades raras, son denominadas así porque afectan a un número reducido de personas al compararlas con la población general. Hay que tomar en cuenta, que una enfermedad puede ser rara en una región del mundo y ser común en otra. Su número va en aumento, y en la actualidad anda por los siete mil.
A la par de las reconocidas enfermedades raras, encontramos otras que, si bien no son comunes, su incidencia está por encima de las llamadas enfermedades raras. Este es el caso de la enfermedad de Huntington, una afección de tipo hereditario, con baja frecuencia, que ataca las células nerviosas del cerebro, provocando una progresiva degradación de las mismas que se traduce en una afectación en las capacidades funcionales del paciente, llevando a alteraciones del movimiento corporal, del pensamiento y de la conducta.
Lamentablemente, la alteración neurológica antes descrita, que ocasiona esta enfermedad, se presenta con más frecuencia en la gente de edad joven y productiva, que tendrá que llevar esta afectación por el resto de su vida.
Vale la pena destacar que cuando se quiere profundizar en el conocimiento de enfermedades poco frecuentes como la antes mencionada, se apela a la consulta y trabajo en equipo, entre los médicos especialistas, como una manera práctica y efectiva de recoger el mayor número de casos posible. En la patología que nos ocupa, se invitó a participar a todos los neurólogos de Panamá, a través de la Asociación Nacional que los agrupa, asegurándose con ello la mayor cantidad de casos posibles que estaban diseminados en las diferentes entidades de salud que cuentan con este tipo de especialistas. Este accionar dio un fruto permanente, al crearse el Registro Nacional de Enfermedad de Huntington, que continuará captando nuevos casos.
Esta forma de accionar, de trabajo conjunto a nivel nacional, también tiene sus antecedentes en la Región Centroamericana y del Caribe, con esta misma especialidad, ya que liderizada por neurólogos panameños, se han podido llevar a cabo trabajos de investigación en los que se conjunta el esfuerzo de colegas de varios países, lo que conlleva un avance de la ciencia y una proyección ya no regional sino mundial, del quehacer científico del área.
En una región donde la investigación es de por si difícil por varias razones y por ende escaza; estrategias como esta de unir esfuerzos más allá de las fronteras nacionales, representa una herramienta por demás muy valiosa, que muestra que, si se puede llevar a la realidad el trabajo disciplinado en equipo, con una coordinación efectiva, que garantiza el llegar a los resultados deseados.

Des systèmes de signalement du temps aux navires dans les ports français, dans les années 1880. Le cas du port de Bordeaux dans la correspondance de Georges Rayet
Authors: La) Jérôme Noë (de 
Published: August 2022

Au XIXe siècle, la connaissance de l’heure à bord des navires est primordiale pour gérer la navigation. Le système de « time-ball », initialement installé dans les ports anglais à partir de 1829, est peu à peu développé dans différents pays. L’un des arguments pour la fondation d’un observatoire astronomique à Bordeaux fin XIXe est la fourniture de l’heure précise aux navires du port. Les lettres de réponse des directeurs des ports français de Cherbourg, Brest, Rochefort et Toulon au directeur de l’observatoire de Bordeaux, Georges Rayet, qui les a questionnés en 1880, donnent une idée pessimiste de l’efficacité des systèmes installés. Finalement, à Bordeaux, le projet s’enlise dans les débats d’une commission faisant intervenir différentes institutions rivales qui ont peur de perdre leurs prérogatives. Entre-temps, l’unification de l’heure en France a fait son chemin avec le développement des chemins de fer. La radio transmission de l’heure à partir de la Tour Eiffel est mise en place dès 1891.

An Evidence-Based Review on Shirodhara: A Unique Panchakarma Therapy
Authors: Kuldeep  , Shaizi layeeq  , Amit  
Published: August 2022

Shirodhara is a procedure consisting of continuous pouring of a stream of medicated oil, milk, buttermilk, etc. on the forehead of the patient from a specific height for a specified period. Acharya Vagbhatta has described four types of Murdha Tail i.e., Abhyanga, Parishek, Pichu, and Shirobasti, which is successively more beneficial than the previous one. Shirodhara or Shiroparishechan is one of them. Indication of Shirodhara was found in our ancient textbooks in various diseases like Ardhavabhedaka, Suryavarta, Ardita, Pakshaghata, Hanugraha, Akshishula, Nidranasha, Shirogata Vata and Shirahkampa.
In the modern era, it is a very widely used Panchakarma therapy and in this review article, an evidence-based approach is used to define the type, procedure, indication contraindication, mode of action, complications and management and evidence of efficacy etc. of Shirodhara. Based on evidence Shirodhara has been found effective in various disorders like Insomnia, Psoriasis, ADHD in children, Shirah Shoola, essential hypertension, cerebral ischemic stroke and premature ejaculation when accompanied with other treatment modalities. Shirodhara was found effective on subjective as well as scientific parameters or modern biochemical markers parameters in various studies.
