Piezoelectric Energy Harvesting at Circuit Resonance with Active Inductor
(CRAI)
Authors: Zalke Jitendra B. , Pandey Sandeepkumar R. , Kavishwar Radhika T. 
Published: June 2022

Background:
Most of the proposed interface circuits use bulky inductors to enhance the key performance parameter i.e., power transfer efficiency. This sets constraints on the design of power conditioning circuitry for constrained IoT applications.

Objective:
To replace the bulky physical inductor with area optimized components suitable for integrated circuit realization with reduced silicon footprint for constrained applications like Internet-of-Things (IoT).

Method:
This paper presents the implementation of Circuit Resonance with Active Inductor (CRAI) technique based interface circuit design to deliver the maximum power generated from the Piezoelectric Energy (PEH) source to the load.

Results:
Compared to the conventional FWBR technique, the proposed CRAI technique improves ≈2X power delivered to the load.

Conclusion:
The proposed work presents an inductor-less interface circuit for PEH. An active inductor (gyrator) is used to induce ‘IP’ rejection at the PEH circuit resonant frequency to enhance the performance parameters. Since the proposed technique is based on active inductor, it can be easily fabricated in small integrated circuit (IC) packages, allowing integration with state-of-the-art constrained IoT applications. CRAI technique based on the rejection of ‘IP’ at the resonance using active inductor is first reported here. The proposed concept is non-adiabatic, but it could be used for constrained self-powered autonomous IoT applications and it could be of importance in guiding the design of new interface circuits for PEH.

ABSTRACT

Objectives
To assess the correlation between malocclusion and a history of bullying.

Materials and Methods
A cross-sectional study of 494 adolescents aged 12 to 15 years was conducted. The National School Health Survey questionnaire (PeNSE 1 and 2) was used to determine history of bullying by identifying the victim and the abuser. Variables were evaluated based on the individual (age), environment (income, father's and mother's education, housing, government assistance, and parents' occupation), social and emotional well-being (CPQ11–14 domains), self-perceived need for orthodontic treatment, and clinical conditions (crowding, diastema, maxillary and mandibular overjet, and anterior open bite). Data were analyzed by Spearman correlation and by multivariate analysis, which allowed graphical representation of the eight variables studied in only two dimensions.

Results
There was no correlation between bullying and variables related to the individual and the environment. Maxillary overjet and self-perception related to the need for orthodontic treatment were important to explain the data variability.

Conclusions
Malocclusion did not correlate with bullying history. However, increased maxillary overjet influences adolescent self-perception, suggesting a potential condition for bullying events.

OBJECTIVE
We compared arterial stiffness and heart rate variability (HRV) over time by diabetes type and determined the risk factors associated with worsening arterial stiffness and HRV in young adults with youth-onset diabetes.

RESEARCH DESIGN AND METHODS
Arterial stiffness (pulse wave velocity, augmentation index) and six indices of heart rate variability were measured twice, 4.5 years apart, among participants with either youth-onset type 1 or type 2 diabetes in the SEARCH for Diabetes in Youth study. Multivariable linear regression models were used to assess risk factors associated with arterial stiffness and HRV at follow-up.

RESULTS
Of 1,159 participants studied, 949 had type 1 diabetes (mean age 17.1 ± 4.7 years, 60.3% non-Hispanic White, 55% female) and 210 had type 2 diabetes (mean age 22.1 ± 3.5 years, 23.8% non-Hispanic White, 71% female) at initial assessment when diabetes duration was 7.9 years (both groups). Participants with type 2 versus type 1 diabetes had greater arterial stiffness and more abnormalities in HRV at initial and follow-up assessment and a greater change over time (all P &lt; 0.05). Risk factors associated with worse arterial stiffness and HRV at follow-up in both types of diabetes included higher blood pressure, hemoglobin A1c, waist circumference, and triglycerides over time and longer diabetes duration.

CONCLUSIONS
Arterial stiffness and HRV worsened over time with greater changes among participants with type 2 versus type 1 diabetes and among those with features of the metabolic syndrome. The risk factor profile documents potentially modifiable pathways to prevent or limit cardiovascular complications in young adults with youth-onset diabetes.

Abstract
Multiple renal cysts in adult patients could have asymptomatic, benign and a nonprogressive course. However, these cysts could be renal features of a very rare hereditary, progressive syndrome defined as cranioectodermal dysplasia (CED or Sensenbrenner syndrome). Affected patients show dysmorphic features such as craniosynostosis, nail dystrophy, cutaneous dyshydrosis, dry or scaly palmar skin, trichodysplasia, deafness, pectus excavatum, telecanthus, hypertelorism, low set ears, everted lower lip, anteverted nares, short neck and height, joint laxity, inguinal hernia, widely spaced teeth, microdontia, hypodontia in addition to nephronophthisis. We report a 22-year-old male hypertensive patient with multiple renal cysts and dental malformations listed as malocclusion, screwdriver shaped crowns, widely spaced front teeth, microdontia and hyperdontia. Molecular analysis reported missense p.(Ala875Thr) and p.(Lys969Asn) variants in the WDR35 gene. The 1-year follow-up of this case provided the knowledge that angiotensin II receptor blocker drug (olmesartan) reduced the microalbuminuria to normal levels and preserved the renal functions. We suggest interdisciplinary studies, especially intraoral and genetic evaluations for patients with cystic renal diseases. For the first time we report that hyperdontia could be found as a dental feature of CED.

Abstract
Importunate high-risk HPV (HR-HPV) infection is the most common trigger for the cervical carcinogenesis process. In this respect, the presence of cancer can be imputed to telomere lengthening or shortening. This paper explores the possible correlation between relative telomere length and viral load in two groups of women, namely: those with high-risk HPV infection and those who do not have this infection. Thus, samples comprising of 50 women in each group were evaluated for this research. The Amplisens HPV HCR screen-titre-FRT PCR kite was employed for quantitative analysis. Relative telomere length was quantified by real-time PCR. In each of the two HPV load groups, there was no correlation between age and telomere length. Telomere shortening was found in the cervical cell samples of women with high HPV loads, compared with women in the control group. Telomere shortening is associated with elevated HPV loads.

Abstract
Despite of nearly 100 years of turbine engine development and design, blade vibrations remain a great engineering challenge. The rotating turbine blades’ vibrations lead to cyclic oscillations, which result in alternating stress and strain in harsh environments of high temperature and pressure. In modern aeroengines, high hot flow velocities might generate erosion and corrosion pitting on the metal surfaces, that leverage remarkably mean stresses. The combination of both mean and alternating stresses can lead to unexpected engine failures, especially under resonance conditions. Then, alternating stress amplitudes can exceed the safety endurance limit, what accelerates the high cyclic fatigue leading quickly to catastrophic failure of the blade. Concerning the existing state-of-the-art and new market demands, this paper revises forced vibrations with respect to excitation mechanisms related to three design levels: (i) a component like the blade design, (ii) turbine stage design consisting of vanes and blades and (iii) a system design of a combustor and turbine. This work reviews the best practices for preventing the crotating turbine and compressor blades from High Cyclic Fatigue in the design process. Finally, an engine commissioning is briefly weighed up all the pros and cons to the experimental validations and needed measuring equipment.

The intersection graph of a finite group G is a graph (V,E) where V is a set of all non-trivial subgroups of G and E is a set of edges where two distinct subgroups H_i , H_j are said to be adjacent if and only if H_i \cap H_j \neq {e} . This study discusses the intersection graph of a dihedral group D_{2n} specifically the subgraph, degree of vertices, radius, diameter, girth, and domination number. From this study, we obtained that if n=p^2 then the intersection graph of D_{2n} is containing complete subgraph K_{p+2} and \gamma(\Gamma_{D_{2n}})=p.

يعد الطابع التنظيمي للعلاقات بين الدول من بين أهم الملامح الرئيسية التي تميز بها القرن العشرين على أنه عصر التنظيم الدولي، لاسيما بعد زيادة عدد الوحدات السياسية بعد الحرب العالمية الثانية التي تبلورت فيها الإقليمية كظاهرة، فهي ليست حديثة إذ أن هناك العديد من التكتلات كالاتحاد الأوربي التي تطورت فيه فكرة التكتل الإقليمي بشكل بارز، لاسيما في أوربا إذ برز بعد جدل دار حول ما سُمي بالعالمية في مواجهة الإقليمية Global vs. Regional، إذ ذهب أنصار التوجه العالمي بأن إقامة تنظيم عالمي يشمل جميع الدول، كأحسن طريقة لتحقيق السلم والأمن الدوليين، في حين أكد أنصار التوجه الإقليمي على أهمية إنشاء تنظيمات إقليمية لتحقيق ذلك، ومن هنا نشأت نظرية ''السلام الإقليمي'' بعد الحرب العالمية الثانية. ولما كانت قدرات الدول النامية على المنافسة من الضعف بمكان، سعت الكثير من هذه البلدان إلى الأخذ بصورة أو بأخرى من صور التعاون الإقليمي بهدف تعزيز قدرتها الاقتصادية في مواجهة تلك التحديات. وفي هذا الإطار تمثل تجربة « رابطة جنوب شرق آسيا » والمعروفة اختصارا بــ الآسيانASEAN نموذجاً متميزاً في هذا الصدد على النحو الذي دفع إلى عدها نموذجاً قابلاً للاحتذاء من جانب الدول النامية في سعيها لتعظيم مكاسبها ضمن الواقع الدولي المعاصر. ومن هنا تأتي أهمية هذه الورقة البحثية التي تسعى إلى التعرف على عوامل نجاح او عجز تجربة « الآسيان » في تحقيق الأمن الإقليمي ومكامن ضعفها والتحديات والصعوبات التي تواجهها وكيف تتعامل معها، وصولاً إلى التعرف على مدى إمكانات الاستفادة من هذه التجربة في إطار المنطقة العربية.

لقد أصبحت اليوم الدول القزوينية الخمس المتشاطئة على سواحل بحر قزوين (كازاخستان، تركمانستان، أذربيجان، روسيا، وإيران) واجهة للأطماع والتنافس الدولي والإقليمي ولاسيما في ضوء المميزات والخصائص التي حبتها بها الجغرافية الطبيعية وتمتعها بمجموعة من الثروات الاقتصادية والمعدنية غير المستغلة بالشكل الأمثل لحد الآن, مما جعلها منطقة جذب استراتيجي للتوجهات والتدخلات الدولية ولاسيما الغربية منها, فكانت معتركاً للشركات العالمية الكبرى الرامية الى احتكار الاستثمارات الصناعية الواعدة من اجل فرض السيطرة والنفوذ إلى موارد المنطقة وثرواتها الاقتصادية ومن ثم فرض سياساتها الخارجية وترتيباتها العسكرية والأمنية على دول منطقة بحر قزوين _ القوقاز ودول منطقة الحوض بشكل اوسع.
وعليه فقد شغلت هذه المنطقة مكانة متميزة في أجندة مخططي السياسات الدولية الكبرى، لاسيما بعد تفكك الاتحاد السوفيتي واشتداد وطأة التنافس الدولي والإقليمي في المنطقة، ليس فقط من أجل السيطرة على موارد الطاقة (كالنفط والغاز الطبيعي) الغنية فيها، بل لتحقيق مكاسب جيوسياسية وإستراتيجية بعيدة المدى، فالولايات المتحدة الأمريكية لم يكن بمقدورها رؤية المنطقة بعيدة عن توجهاتها السياسية التي تزامنت مع إعلانها عن قيام (النظام العالمي الجديد)، كما أن روسيا الاتحادية تسعى إلى استعادة مكانتها الدولية مجدداً منذ وصول الرئيس فلاديمير بوتين للسلطة مطلع عام 2000 وهو الأمر الذي فرض عليها استعادة مكانتها ونفوذها الجيوبوليتيكي في دول الخارج القريب (أسيا الوسطى والقوقاز)، فضلاً عن المنافسة الدولية للقوى الصاعدة والتي تبديها كلاً من الصين والهند وإيران وتركيا, وهو الأمر الذي شكل تنافساً وصراعاً دولياً محتدماً في المنطقة, إذ إن الموقع الجغرافي الحبيس لجمهوريات المنطقة، ولـــــّد إشكالية مزدوجة سياسية – اقتصادية تمثلت بعدم إمكانية دول المنطقة للاستفادة المباشرة من مواردها المعدنية والهيدروكاربونية ما لم تلجأ إلى استعمال أراضي وموانئ الدول المجاورة لها، والتي تعاني اغلبها من ظاهرة عدم الاستقرار السياسي والاجتماعي، مما فرض بروز مجموعة من التحديات التي تستند إلى خصوصية التدخلات الأمريكية- الروسية في دول حوض بحر قزوين- القوقاز ما بعد العام 2001 ضمن إطار تكتيل وتعزيز استدامة استراتيجيات فرض السيطرة والنفوذ من كل من الولايات المتحدة الأمريكية وروسيا الاتحادية حيال المنطقة.
