В роботі досліджено процеси концентрування розчинів хлориду натрію методом електродіалізу. Враховуючи дефіцит реагентів, їх високі ціни, даний метод електродіалізу можна реалізувати для отримання кислоти і лугу з розчинів сульфату натрію, лугу, алюмінієвих та залізних коагулянтів. На сьогоднішній день технології, котрі в результаті проведення їх основних процесів, дозволяють в якості вторинного продукту отримати цінні матеріали, речовини, продукти, коагулятни, є дуже виправданними, економічно доцільними та, головне, дозволяють успішно впровадити принципи маловідходних виробництв. Маловідходні технології являють собою такі методи виробництв продукції, при яких вся сировина і енергія використовуються найраціональніше і найкомплексніше в циклі «сировинні ресурси — виробництво — споживання — вторинні ресурси» і впливать на навколишнє середовище, не порушують його нормальний стан. . Суть процесу полягає у використанні розчинів хлориду натрію, що утворюється при знесоленні води зворотнім осмосом у вигляді концентратів. Кращим є використання електролізу. Особливо, якщо врахувати високі показники, отримані при концентруванні хлориду натрію електродіалізом Процес концентрування реалізовували у трикамерному електролізері, в катодній, анодній та робочій областях було розміщено розчин хлориду натрію, концентрацією 360 ммоль/дм3. В анодній області було використано розчин лугу концентрацією 480 мг-екв/дм3. При проведенні електролізу в катодній області утворювався луг, за рахунок дифузії натрію у робочій області та катодного відновлення води. Хлориди із робочої області переходили в анодну область. Гідроксид-аніони на аноді окислювались до кисню, хлориди з натрієм утворювали хлористий натрій, концентрація якого зростала до 660 мг-екв/дм3. Лужність знижувалась до 68-70 мг-екв/дм3. При зміні катодів і анодів місцями процес повторювали до підвищення лужності в катодній зоні та концентрації хлоридів в анодній зоні. . В робочу зону, де відбувалось знесолення води, додавали розчин хлориду натрію, концентрацією 360 ммоль/дм3. В перспективі доцільно провести процеси концентрування хлоридів в аноліті за умови утворення активного хлору та окислення сполук хлору в герметичному електролізері з урахуванням можливих втрат Cl2 та ClO2 при випаровуванні.

However, this material was synthesized by a solid-state process, resulting in larger particle size and nonuniform morphology. The larger particle size will sluggish the Na ion diffusion. Here we report the synthesis of Na<sub>2/3</sub>[Fe<sub>1/2</sub>Mn<sub>1/2</sub>]O<sub>2</sub> using a simple sol-gel process. The X-ray diffraction revealed that the sample was identified as Na<sub>2/3</sub>[Fe<sub>1/2</sub>Mn<sub>1/2</sub>]O<sub>2</sub> with a hexagonal crystal structure. However, the impurities are formed at diffraction angles of 36.28°, 45.03°, and 51.23°. Calcination temperature affects the formation of the crystal phase, grain growth, morphology, and particle size.

Authors: Di Muro Andrea , Taha Zyad Ayman , Corti Jacopo , Frasconà Fabio , Matassi Fabrizio 
Published: May 2024

Case:
This report describes a new pattern of meniscal tear in an 18-year-old man after a knee sprain; he had undergone anterior cruciate ligament revision (ACL-R) 3 years earlier. He was diagnosed with an anterior cruciate ligament (ACL) graft rupture, a ramp lesion (Thaunat type 4), and a posterior root avulsion fracture of the medial meniscus (MM) (LaPrade type 5). He was treated successfully with an all-inside repair of the ramp lesion, a transtibial pull-out repair of the root tear, and ACL graft revision and anterolateral stabilization.

Conclusion:
This specific meniscal injury pattern should be recognized and documented, potentially warranting consideration as a new addition to Thaunat and LaPrade classifications as type 6.

Published: May 2024

Introduction:
The role of elective rotations in the orthopaedic residency selection process varies between programs. Our study aims to identify factors associated with residency programs that interview and match a greater proportion of applicants who have completed an elective rotation with their program.

Methods:
Data were collected through the American Orthopaedic Association's Orthopaedic Residency Information Network database. Bivariate correlations and multivariate regression models were used to identify independent predictors of programs with a greater proportion of interviewees or residents who completed an elective rotation at the respective program.

Results:
One hundred seventy-eight of the 218 existing residency programs were included in this study. Programs that offered fewer interviews and more away rotation positions per year were associated with a greater odds of its interviewees (OR = 0.36, p = 0.01; OR = 4.55, p < 0.001, respectively) and residents (OR = 0.44, p = 0.04; OR = 4.23, p < 0.001, respectively) having completed an elective rotation with the program. In addition, programs with fewer attendings (OR = 0.39, p = 0.03) and in-person interviews (OR = 3.04, p = 0.04) matched a greater proportion of their rotators. However, programs that interviewed applicants during the elective rotation were less likely to match their rotators (OR = 0.35, p = 0.04).

Conclusion:
Certain program characteristics independently predict the likelihood of a program interviewing and matching their rotators. These findings may provide information for applicants and programs regarding the rotation process.

Published: May 2024

Abstract

In quality education, we except good teaching. To improve the academic performance of a student it is important to monitor the students’ activities and attentiveness. The traditional way to do that is Examination and regular counselling; But an exam can’t conclude overall academic performance of a student, counselling is not enough to estimate the difficulties that students are facing in classroom, the level of attention of students in classroom and the favorite subjects of the students. And it’s also important to monitor the teachers’ teaching quality. In this work we proposed an AI model, by which we can analysis the students’ emotion, activities and attentiveness in the classroom with the help of high-resolution configured camera in the classroom. The model detects the facial expressions of each student in classroom to recognize the emotion of each student; and detect the eyes, lips and head movement of each student to recognize the activities of the students. And analyze these recognized activities for each student to classify the attentiveness status (attentive or inattentive) of each student. And an overall activities and emotion of all the students will be analyzed to evaluate the teacher’s teaching quality at the class – If most of the students are inattentive or not happy, means the teacher’s teaching methods is not helping the students and vice versa. The proposed machine leaning model not only analyze performance of the student and teaching method, it also alerts the teachers about the unwanted activities of the student in the classroom in real-time.

Abstract

Background:
Flash glucose monitoring (FGM) can improve diabetes management, but no randomised controlled trials (RCTs) of FGM have been undertaken in Indigenous Australian populations. This study aimed to assess the feasibility of performing a RCT of FGM in Indigenous Australians with type 2 diabetes.
Methods:
In this open-labelled pilot RCT, Indigenous adults with type 2 diabetes were randomised to FGM or standard care for 6 months. Eligible participants were being treated with injectable diabetes medications and had a glycosylated haemoglobin (HbA1c) ≥ 7.0%. The feasibility outcome was the proportion of participants completing the trial. The preliminary effective outcome was the change in HbA1c. Secondary effectiveness outcomes included a change in time spent in target blood glucose; safety (hypoglycaemic episodes); and quality of life (EuroQol 5-Dimension 3-Level (EQ-5D-3L) score).
Results:
Of 126 screened individuals, 74 were eligible, 40 (31.7%) were randomised and 39 (97.5%) completed the study. Participants’ baseline characteristics were similar between the FGM and usual care groups, except for sex and body mass index. There were no between-group differences for: change in HbA1c; percentage of time spent in target blood glucose, low glucose and high glucose; or EQ-5D-3L scores. No severe hypoglycaemic episodes occurred.
Conclusions:
This is the first pilot RCT of FGM in Indigenous Australians with type 2 diabetes. The results support a larger RCT, which is currently in progress.
Trial registration:
Australian New Zealand Clinical Trials Registry (ANZCTR12621000021875), retrospectively registered on 14 January 2021.
Glucose oxidase coupling with pistol-like DNAzyme based colorimetric assay for sensitive glucose detection in tears and saliva
Authors: Fan Jiaying , Zhou Kai , Wang Jin 
Published: May 2024

Abstract

Measuring glucose levels in tears and saliva is important for diagnosing and predicting several diseases without the need for intrusive procedures. Detecting low concentrations of glucose with high sensitivity is still a significant difficulty. A simple visual method was created to assess glucose levels in tears and saliva by utilizing glucose oxidase (GOx) to catalyze glucose and pistol-like DNAzyme (PLDz) for signal amplification. Specifically, the β-D-glucose in samples acts as the initial molecule that is identified and catalyzed by GOx to produce gluconic acid and H2O2. H2O2 triggered the self-cleavage of PLDz, resulting in the activation of the “part b” sequence to initiate catalytic hairpin assembly (CHA) and release the DNAzyme section in H1 probe. The DNAzyme functions as a peroxidase mimic, catalyzing the TMB–H2O2 system and leading to an increase in observable signals. The proposed approach demonstrated a low limit of detection of 0.32 µM and a broad detection range. Moreover, the proposed approach was effectively used to detect glucose in tears and saliva samples, indicating potential for diagnosing hyperglycemia-related disorders in clinical settings.

Abstract

Achieving a correlative measurement of both magnetic and atomic structures at the nanoscale is imperative to understand the fundamental magnetism of matters and for fostering the development of new magnetic nanomaterials. Conventional microscopy methods fall short in providing the two information simultaneously. Here, we develop a new approach, large-angle Lorentz 4-dimensional scanning transmission electron microscopy (LA-Ltz-4D-STEM), to simultaneously map the magnetic field and atomic structure at the nanoscale. This method enables precise measurement of the characteristic atomic and magnetic structures across an extensive field of view, a critical aspect for investigating real-world ferromagnetic materials. The pixel-by-pixel correlation of the different information offers comprehensive visualization and statistical evaluation of the nanoscale magnetic phenomena. We applied the new method to directly visualize the magnetoelastic coupling as well as the competition between magnetoelastic and magnetostatic energy in an amorphous ferromagnet. This approach opens new avenues for in-depth studying the structure-property correlation of nanoscale magnetic materials.
