Published: September 2023

مقاومت آنتی بیوتیکی که به دلیل استفاده بیش از حد آنتی بیوتیک ها در درمان، افزایش پیدا کرده به یک چالش در از بین بردن باکتری ها تبدیل شده است که با عواقب سنگین مالی و انسانی در سراسر دنیا همراه می باشد. مقاومت باکتری های بیمارستانی یک نگرانی عمده است و هدف بسیاری از تحقیقات علمی، ایجاد استراتژی هایی برای پیشگیری از مقاومت به آنتی بیوتیک ها می باشد. میدان های شعوری طاهری (ط) به عنوان میدان های جدید توسط محمد علی طاهری معرفی شده است. این میدان ها نه ماده هستند و نه انرژی، بنابراین مستقیما قابل اندازه گیری نیستند. اما مطالعه اثرات آنها از طریق آزمایش های کنترل شده امکان پذیر است. پس از بررسی اثر میدان شعوری فرادرمانی (FCF) بر جمعیت های باکتریایی در مطالعه قبلی، هدف این مطالعه بررسی اثر FCF بر مقاومت آنتی بیوتیکی سویه های باکتری شناخته شده بیمارستانی بود. با استفاده از روش های دیسک دیفیوژن و MIC، مشاهده کردیم که مقاومت جمعیت های باکتریایی تغییر کرد. به ویژه، سویه های Pseudomonas. aeruginosa, Echerichia.coli, Bacillus. subtilis, Klebsiella. pneumoniae, Acinetobacter. bummani و Staphylococcus. aureus یک کاهش مقاومت آنتی بیوتیکی نشان دادند در حالیکه سویه های S.aureus و P.aeruginosa افزایش مقاومت به آنتی بیوتیک را نشان دادند. بر اساس نتایج بدست آمده، میدان شعوری فرادرمانی می تواند بر پاسخ مقاومت آنتی بیوتیکی در جمعیت های مقاوم اثر بگذارد. این مشاهده به بررسی تکمیلی نیاز دارد. با تکرارپذیری این مشاهدات توسط محققان دیگر، می توان میدان شعوری فرادرمانی را به عنوان یک راه حل برای این مشکل جهانی در نظر گرفت.
تغییرات جرم سیلیس خالص تا 1000 درجه سانتیگراد تحت تأثیر میدان پیوند شعوری طاهری: مطالعه تئوری شعور طاهری
Authors: کزازی بهاره , طاهری محمد علی 
Published: September 2023

طبق نظریه طاهری، شعور (ط) میتواند به ماده و انرژی تبدیل شود و بالعکس. میدان پیوند شعوری یکی از میدان های شعوری طاهری است که توسط محمد علی طاهری به عنوان میدان هایی جدید معرفی و برقرار شده است. این میدانها نه ماده هستند و نه انرژی؛ بنابراین کمیت ندارند اما تأثیر مستقیم بر ماده و انرژی دارند. به عبارت دیگر، اگرچه میدان های شعوری (ط) را نمیتوان به طور مستقیم اندازه گیری کرد، اما میتوان اثرات آنها را به طور غیر مستقیم از طریق آزمایشهای تکرار شونده بررسی کرد. مطالعه ی حاضر باهدف بررسی این فرضیه با اندازه گیری تغییر جرم سیلیس خالص از طریق فرآیند گرمایش انجام شده است. نمونه های ساخته شده از پودر سیلیس خالص 95 درصد با اندازه ذرات تقریبا 1700 نانومتر از یک بسته و تحت شرایط یکسان تحت آنالیزهای حرارتی زیر قرار گرفتند: DTA ( آنالیز حرارتی تفاضلی)، DSC (گرماسنجی افتراقی (TGA)، وزن سنجی حرارتی). آنالیزها بر روی دو مجموعه از نمونه ها، یک گروه از نمونه ها تحت تأثیر میدان پیوند شعوری (ط) و گروه دیگر به عنوان نمونه های شاهد انجام شد. نمونه های 6 میلیگرمی با نرخ رشد دما 10 درجه سانتیگراد بر دقیقه، در محدوده ی دمایی 25 تا 1000 درجه سانتیگراد، در هوا، تحت استاندارد E1131-ASTM حرارت داده شدند. نتایج نشان داد که هیچ تغییری در ساختار سیلیس خالص مانند ذوب یا تبدیل و غیره وجود ندارد. از طرف دیگر، نمونه های در معرض میدان شعوری (ط) به طور متوسط 722 درصد در دمای 350 درجه و درمجموع 141 درصد در دمای نهایی جرم بیشتری نسبت به نمونه های شاهد از دست دادند. بر اساس مشاهدات عینی نتایج، مشخص میشود که این تفاوت معنی دار هیچ توضیح مادی قابل قبولی ندارد و بنابراین حاکی از وجود میدان شعوری (ط) است که اعمال شده است. همچنین اثباتی بر نظریه طاهری مبنی بر تبدیل شعور (ط) به ماده و انرژی است.

Authors: de Kock Eleanor , Yelverton Christopher , Myburgh Cornelius 
Published: September 2023

ABSTRACT

Objective
To update the state of the art regarding the acquisition of spinal high-velocity low-amplitude psychomotor skills competency among chiropractors and chiropractic students.

Methods
Available electronic articles from 5 databases, published between June 2015 and August 2020, were obtained. Eligible studies underwent methodological quality assessments using the Joanna Briggs Institute Critical Appraisal Checklists and Cochrane Collaboration's Risk of Bias Tools.

Results
Fourteen critically appraised studies were identified, including 10 cohort studies and 4 randomized controlled trials. There was no literature excluded due to high risk of bias. The type of augmented devices included a mannequin on a force platform, a computer-connected device, a human analogue mannequin, and a 3-dimensional electrogoniometer with an instrumented spatial linkage.

Conclusion
The use of augmented feedback devices such as human analogue mannequins with force-sensing table technology and computer-connected devices is potentially beneficial in the chiropractic curricula and may facilitate student learning and improvement of spinal manipulation. More studies are required to determine whether psychomotor skill aids translate directly into raised competency levels in novice clinicians.
Challenges Faced by International Students in Pursuing Doctoral Study: A Case Study of Saudi Students in American Higher Education Programs
Authors: Khawaji Ahmed 
Published: September 2023

Many international students aspire to seek admission to higher education and pursue their studies, especially in the US. Therefore, institutions in general and American institutions in particular must realize the students' perspectives and offer support so they can face their unique problems during their education. This review aims to look into specific learning and adaptation-related experiences of international higher education students during a challenging transition to a large, public research university in the United States. The study was conducted at an American university in the southwest. The program enrolls students worldwide seeking master's and doctoral degrees in languages and social studies. Students may select from a wide range of concentrations, such as teaching English as a Second Language, bilingual education, and social justice, to name a few. These students are often encouraged to study interdisciplinary subjects to improve their understanding of the realm of education and how it is affected by society and politics. Professors teaching these interdisciplinary subjects who descend from various countries and teach in multiple disciplines hold controversial and sometimes even contradicting visions on education and research issues. This review explored the challenges and problems that Saudi international students face while pursuing higher education. A qualitative data collection and analysis method was followed to arrive at conclusions. 6 Saudi students were interviewed in detail. Study findings revealed various academic, social, cultural, financial, and family implications. It is concluded that Saudi international students encounter specific difficulties in US institutions, such as mentoring hardships, adjustment to a new educational system, lack of administrative support, and communication gaps between the supervisors and the researchers.

Published: September 2023

Background: Acute recurrent tonsillitis is a common problem worldwide and tonsillectomy is the preferable treatment for patients not responding to medical treatment. Many patients with acute recurrent tonsillitis and increased antistreptolysin O (ASO) titers are caused by group A beta hemolytic streptococcal (GABHS) tonsillitis, which can lead to serious side effects such rheumatic fever and glomerulonephritis. ‎
Aim: To assess the consequence of tonsillectomy on ASO titer.
Patients and Method: This prospective study was conducted to analyze the consequence of tonsillectomy on 43 patients with raised antistreptolysin O (ASO) titer out of 220 patients with acute recurrent tonsillitis, for the period from October 2015 to October 2016 at Otolaryngology department, Tertiary referring hospital at Erbil, Kurdistan/Iraq. Their Demographic characteristics, medical, drug and family history and disease extent were analyzed. Postoperative follow up were processed.
Results: The study included 43 patients between 3 to 16 years suffering from acute recurrent tonsillitis, elevated ASO titer (≥200 IU/ml) and positive throat swab for GABHS were included in the study. Six months postoperatively had been shown that there is a significant reduction in ASO titer in comparison to preoperative measures (p < 0.001) and this is also applicable to the number of sore throat episodes.
Conclusion: The main conclusion from this study is significant effect of tonsillectomy on decreasing ASO titer which reveals the reduction in postoperative GABHS throat infection, this supported by reduction of postoperative sore throat episodes.

Published: September 2023

Aims: We aimed to investigate the prognostic value of the tricuspid annular plane systolic excursion (TAPSE)/ pulmonary arterial systolic pressure (PASP) ratio in Moroccan patients with heart Failure (HF).
Study Design: A retrospective study was conducted in The Cardiology Department of Ibn Rochd Hospital of Casablanca in Morocco. The study was conducted in the period between March 2012 to March 2016 with a follow-up until December 2022.
Methods: data were evaluated from the HF register patients and their relatives were contacted by phone. Patients with reduced LVEF were included, patients with pulmonary embolism, and patients with HFpEF were excluded. The endpoint of the study was mortality.
Results: 128 patients were enrolled Over an average follow-up of 58 months. 51(41.4%) patients died at the end of the follow-up, the median value of left ventricular ejection fraction was 35.2 ± 2.2%. Patients were stratified according to the TAPSE/PASP ratio (low <0.32 mm/mmHg; high: >0.32 mm/mmHg). Kaplan-Meier survival analysis showed that ten-year all-cause mortality was significantly higher in patients with TAPSE/PASP ≤0.32 mm/mmHg than in patients with TAPSE/PASP > 0.32 mm/mmHg (log-rank 7.8, p =0.008) Cox regression analysis revealed that lower LVEF (p= 0.04), and a ratio of TAPSE\PAPS <0.32 (p=0.02) were associated to an increase in all-cause mortality.
Conclusion: Correlating right ventricular function to loading conditions may be more accurate in assessing its real contractility and predicting patients’ outcomes. Our study showed that TAPSE/PASP appears as a novel prognostic predictor in patients with Heart failure.

Published: September 2023

The present study was focused on the evaluation of foliar spray treatment to arrest the flower drop in order to increase the seed set and seed yield in greengram. The crop of greengram var.CO 8 was raised by adopting the recommended package of practices during rabi season during 2019 and 2020 at Department of Seed Science and Technology, TNAU, Coimbatore. Foliar application of different nutrients viz., Nutrigold 0.50%, ZnSO4 0.10%, Mono ammonium phosphate 2%, as treatments were sprayed at bud initiation (30 days after sowing) and 7 days after flowering stages. Pulse wonder @ 5 kg ha‑1 was sprayed during peak flowering stage. Unsprayed plots served as control. During the investigations, data on flower production, arresting of flower drop, seed set, seed filling, seed yield and quality of greengram were recorded and studied.
In the study, significant variations were observed due to the foliar applications. Days to 50 per cent flowering, number of flowers per plant, number of pods per plant, conversion efficiency percentage, pod yield ha-1and seed yield ha-1were significantly higher with foliar spray of Nutrigold 0.50% applied at bud initiation and 7 days later which was on par with Pulse wonder @ 5 kg ha‑1 applied during peak flowering stage. The percentage of flower drop was less in Nutrigold 0.50%(39.69%) which was on par with Pulse wonder @ 5 kg ha‑1 (41.04%) when compared to control (52.02%). Seed quality parameters such as seed recovery, 100 seed weight, seed germination and vigour of seedlings were significantly higher in foliar spray of Nutrigold 0.50% when compared to other treatments.
From this study, it could be concluded that the foliar application of Nutrigold 0.50% during bud initiation and 7 days after flowering or Pulse Wonder @ 5kg/ ha during peak flowering could be effectively applied to maximize the flower production, arrest the flower drop and to improve the seed yield and quality in greengram.

AbstractOrganic electrochemical transistors (OECTs) based complementary inverters have been considered as promising candidates in electrophysiological amplification, owing to their low power consumption, and high gain. To create complementary inverters, it is important to use highly stable p‐type and n‐type polymers with well‐balanced current. In this study, the electrochemical stability of p‐type ladder‐conjugated polymer‐based OECT is improved through an annealing process that maintains its doped‐state drain current from 76% to 105% after 4,500 cycles in ambient environment. Next an OECT‐based complementary inverter made from p‐type and n‐type ladder‐conjugated polymers (PBBTL and BBL) that possess ultra‐low power consumption (≈170 nW), high gain (67 V/V), and high noise margin (92%) with full rail‐to‐rail swing, is presented. Furthermore, its potential for amplifying the envelope of surface electromyography (EMG) for robotic hand control is demonstrated. The high variation in the output (0.35 V) allows the amplified EMG signals to be directly captured by a commercial analog‐to‐digital converter, which in turn controls the robot hand to grasp different objects with low delay and low noise. These results demonstrate the capability of OECT inverter‐based amplifier in future signal processing‐free human‐machine interface, particularly useful for prosthetic control and gesture control applications.

AbstractThe development of high‐efficiency thickness‐insensitive organic solar cells (OSCs) is crucially important for the mass production of solar panels. However, increasing the active layer thickness usually induces a substantial loss in efficiency. Herein, a ternary strategy in which an oligomer DY‐TF is incorporated into PM6:L8‐BO system as a guest component is adopted to break this dilemma. The S···F intramolecular noncovalent interactions in the backbone endow DY‐TF with a high planarity. Upon the addition of DY‐TF, the crystallinity of the blend is effectively improved, leading to increased charge carrier mobility, which is highly desirable in the fabrication of thick‐film devices. As a result, thin‐film PM6:L8‐BO:DY‐TF‐based device (110 nm) shows a power conversion efficiency (PCE) of 19.13%. Impressively, when the active layer thickness increases to 300 nm, an efficiency of 18.23% (certified as 17.8%) is achieved, representing the highest efficiency reported for 300 nm thick OSCs thus far. Additionally, blade‐coated thick device (300 nm) delivers a promising PCE of 17.38%. This work brings new insights into the construction of efficient OSCs with high thickness tolerance, showing great potential for roll‐to‐roll printing of large‐area solar cells.

AbstractFreestanding single‐crystalline nanomembranes and their assembly have broad application potential in photodetectors for integrated chips. However, the release and self‐assembly process of single‐crystalline semiconductor nanomembranes still remains a great challenge in on‐chip processing and functional integration, and photodetectors based on nanomembrane always suffer from limited absorption of nanoscale thickness. Here, a non‐destructive releasing and rolling process is employed to prepare tubular photodetectors based on freestanding single‐crystalline Si nanomembranes. Spontaneous release and self‐assembly are achieved by residual strain introduced by lattice mismatch at the epitaxial interface of Si and Ge, and the intrinsic stress and strain distributions in self‐rolled‐up Si nanomembranes are analyzed experimentally and computationally. The advantages of light trapping and wide‐angle optical coupling are realized by tubular geometry. This Si microtube device achieves reliable Ohmic contact and exhibits a photoresponsivity of over 330 mA W−1, a response time of 370 µs, and a light incident detection angle range of over 120°. Furthermore, the microtubular structure shows a distinct polarization angle‐dependent light absorption, with a dichroic ratio of 1.24 achieved at 940 nm. The proposed Si‐based microtubes provide new possibilities for the construction of multifunctional chips for integrated circuit ecosystems in the More than Moore era.
Conducting Polymer Coatings Prepared by Mixed Emulsions Are Highly Conductive and Stable in Water

Published: September 2023

AbstractAn aqueous emulsion of conducting polymer is commonly applied on a substrate to form a coating after drying. The coating, however, disintegrates in water. This paper reports a coating prepared using a mixture of two emulsions: an aqueous emulsion of conducting polymer, and an aqueous emulsion of hydrophobic and rubbery chains copolymerized with silane coupling agents. When applied on a substrate and dried, particles of the mixed emulsion merge into a continuous film. While the conducting polymer forms percolated nanocrystals, the silane groups crosslink the rubbery chains and interlink the rubbery chains to the substrate. The percolated nanocrystals make the coating highly conductive. The covalent network of hydrophobic polymer chains stabilizes the coating in water. The high conductivity and stability in water may enable broad applications.
