Authors: Костенко М.О. , Зуев Я.И. , Овечкина А.А. , Курыкин М.А. , Паренаго О.О.
Published: February 2025

Получены данные о растворимости моногидрата гексафторацетилацетоната меди(II) Cu(hfa)2⋅H2O в диоксиде углерода. Растворимость увеличивается с ростом температуры в диапазоне 303—353 К и наблюдается ее нелинейный рост с ростом плотности CO2 в сверхкритической (СК) области. Зависимость растворимости от параметров состояния (температура, плотность CO2) описана уравнением Крастила. Изучена адсорбция Cu(hfa)2⋅H2O из раствора в СК-CO2 на трех образцах γ-Al2O3, различающихся наличием кислотных и основных добавок. Изотермы адсорбции имеют форму, характеризующуюся резким ростом величины адсорбции на начальном участке, что свидетельствует о высоком сродстве комплекса к поверхности носителя и/или ее гетерогенности, и наличии центров с высокой энергией адсорбции. Увеличение плотности CO2 от 355 до 780 кг/м3 при постоянной температуре (313 К) приводит к снижению адсорбции Cu(hfa)2⋅H2O на всех трех образцах Al2O3. При постоянной плотности среды 355 кг/м3 и повышении температуры от 313 до 343 К наблюдается более сложный характер поведения изотерм адсорбции в зависимости от характеристик носителя и диапазона концентраций адсорбируемого вещества.

The data on the solubility of copper(II) hexafluoroacetylacetonate monohydrate Cu(hfa)2⋅H2O in carbon dioxide. The solubility increases with increasing temperature in the range of 303—353 K and a nonlinear increase in the solubility of Cu(hfa)2⋅H2O with increasing CO2 density in the supercritical (SC) range of parameters is observed. The dependence of solubility on the parameters of state (temperature, CO2 density) was described by the Chrastil equation. Adsorption of Cu(hfa)2⋅H2O from its solution in SCCO2 on three samples of γ-Al2O3, differing in the presence of acidic and basic additives, is studied. The adsorption isotherms have a shape characterized by a sharp rise in adsorption at the initial section. This shape indicates a high affinity of the complex to the carrier surface and/or its heterogeneity and the presence of high-energy adsorption centers. An increase in the CO2 density from 355 to 780 kg/m3 at a constant temperature (313 K) leads to a decrease in the adsorption of Cu(hfa)2⋅H2O on all three alumina samples. At the constant density of the medium 355 kg/m3 and the temperature rise from 313 to 343 K, a more complex behavior of the isotherms depending on the carrier characteristics and the range of concentrations of the adsorbed substance is observed.

Authors: - KHATRI GAURAVKUMAR KALPESHKUMAR
Published: February 2025

People are using social media more and more in place of conventional news sources because of the widespread use of social media and cellphones. Although news websites offer verified sources, false information and fake news frequently proliferate unchecked on social media sites like“Facebook, Twitter, WhatsApp, and other microblogging platforms. This unchecked spread of misleading information has the potential to mislead the public and cause needless fear. In this work, an artificial intelligence-based model for Natural Language Processing (NLP)-based false news detection is presented. The Logistic Regression (LR) algorithm is used in the suggested approach to aggregate news information and assess its validity. When compared to other false news detection methods, the model's performance shows that it is successful at differentiating between fake and real news, with an accuracy of 98.6%.”
Changing Dynamics Of Internal Security Threats In Kashmir And Abrogation Of Art.370
Authors: - Charu Sharma , - Sumanpreet Kaur
Published: February 2025

On August 5, 2019, the Indian government took a bold step of abrogation of Art.370 and Art. 35A ending the special status of the state of Jammu & Kashmir and completely aligning it with India. It marked a significant turning point in the political and security context of the State of Jammu and Kashmir. Many hues and cries were raised over the abrogation more internally than externally except a few nations including Pakistan. Rest of the world termed it as an internal matter of India and a bilateral issue. Much has changed since then. From forced lockdown in Kashmir after the abrogation to hosting of a G20 meeting and making Srinagar a smart city, India has come a long way. Terror attacks over security officials and minorities are still there but their number has declined significantly. The special status and the autonomy enjoyed by the State earlier had been an issue of contention for decades. Therefore it is important to explore the changing dynamics of terror in Kashmir after the abrogation of Art.370. This paper tries to explore the reasons behind the abrogation of Art.370, the internal and external reactions to its abrogation, its effects on the insurgency in Kashmir, the immediate consequences of the revocation of Article 370 on the insurgency highlighting the response of the local population, role of Pakistan after the revocation of Article 370, measures taken by the Indian government to address the insurgency in Kashmir post the abrogation.
Overall, this paper tries to provide a brief view of changing dynamics of internal security threats in Kashmir following the revocation of Art.370 and its future implications including immediate ones.
Some Aspects of Descartes Epistemology and Metaphysics
Authors: - Ruman Debnath
Published: February 2025

Rene Descartes was know as father of Modern western philosophy and he was an one of the most prominent Rationalist philosopher. Descartes method of doubt should not be confused with skepticism. He is not asserting that whatever can be doubted is false, but he is only supposing it to be false. He believed that clear and distinct perceptions were a mark of truth. Descartes' metaphysics focused on the basic structure of reality, including the mind-body relationship. He argues that the "Mind" is indivisible and "Body" is divisible. Dualism is the theory that the mental and the physical or mind and body or mind and brain are in some sense, radically different kinds of thing. According to Descartes, is metaphysics, which contains the principles of knowledge, such as the definition of the principal attributes of God, the immaterially of the soul, and of all the clear and simple nations that one is us. Descartes argues that, cogito ergo sum (I think therefore I am) is the first final certainty and as such we have to be careful in it's interpretation as well as in deciding it's position in the Cartesian philosophy.

Management of displaced distal forearm fractures in children
Authors: M. Nouh Hassan , S. Bohalfaya Mabrouk
Published: February 2025

Distal both bones forearm fractures are quite  common injury in children. They are generally treated by closed reduction and casting alone or with added percutaneous pinning with excellent results. The target of this prospective study was to delineate if re-displacement after stable reduction of displaced distal forearm fracture in a child can be prevented by percutaneous fixation with Kirschner wires. A complete of 48 children aged between 2-12 years with displaced distal both bone forearm fracture underwent either conservative treatment by immediate closed reduction and long arm cast in plaster room without anesthesia or surgical procedure by additional fixation with percutaneous Kirschner wires and long arm cast, with  28 had conservative treatment and 20 had surgery. All patients were available for follow-up with average of 6.7 months. Fractures fixed with percutaneous Kirschner wires showed no displacement, compared to three displacements within the fractures maintained by cast alone (chi-squared test, p <0.01). Range of supination and pronation is a smaller amount affected in fractures treated with pinning (6°vs.13°).  Fewer complications were seen within the fractures treated by pinning than in fractures treated by cast alone (5% vs 17.8%). We conclude that the utilization of a percutaneous Kirschner wire to reinforce the reduction of the fracture in children who have a completely displaced metaphyseal fracture of the distal radius may be a safe and reliable way of maintaining alignment of the fracture. Lastly, use of percutaneous Kirschner wires to keep the reduction of the displaced distal forearm fracture in children is reliable method to stop re-displacement of the fracture.

Published: February 2025

Compost is a low-cost technology, environmentally friendly process used to treat organic waste. It has been shown to have several positive impacts when applied to soil on plant growth and some improvements on the physical and chemical properties of soil. It also controls the movements and uptake of metals by plants and animals. The plant species Hordeum vulgare L. (Barley) and Vicia faba L. (Broad bean) were used in this study. The organic fertilizer used was obtained from the local market. The results obtained showed that the application of compost in the soil had increased the growth of both Barley and Broad bean. The data obtained clearly illustrated that the compost used increased the concentration of some metals in the soil and plant especially Fe.  But; the levels of heavy metals found in Barley and Broad bean were generally low and still below the permissible levels recommended by the Food Agriculture Organization (FAO) and the World Health Organization (WHO). Variations of the metals in the plants and soils were in the order of Fe>Zn>Ni. The Transfer Ratio (TR) of the metals from the soil to plants the values obtained found the following trend Fe>Ni>Zn.

Published: February 2025

The use of a laser to accelerate the wound healing process has been extensively studied; however, only a few reports in the area of periodontics being available. The literature regarding laser therapy is inconclusive, some studies showing beneficial effects, while others reported no additional effect at all. Investigations failed to demonstrate effects, possibly because of the large choices of parameters. The purpose of this study is to assess the potential effect of the clinical application of diode laser as an adjuvant for mechanical periodontal treatment in orthodontic patients. Sixteenorthodontic patients (nine females and seven males) with a mean age of 27years±4.41, with a good systemic condition, have been recruited in this study. They were diagnosed with mild-moderate chronic periodontitis (PPD ≥ 4mm). Forty teeth in two different quadrants (contralateral matched pairs)have been studied and the selected sites were randomly categorized into two groups; Group I (Control or SRP group), Group II (Test or SRP + Laser group). Firstly, the selected cases received conventional mechanical debridement, after which the experimental teeth were randomly allocated to either test or control groups. All teeth subjected to scaling, root planing (SRP), and teeth assigned to the test group (SRP + Laser) were irradiated with the 660 nm diode laser twice for 30 s, in two isolated appointments, 1 week apart. The laser technique was used in the continuous mode, with 100mW power output. Clinical parameters included bleeding on probing (BOP) and probing pocket depth (PPD) were measured and data collected at baseline, 2 weeks, 4 weeks, and 6 weeks after therapy. The clinical comparison was performed throughout the study period, to show the actual performance of the two therapeutic modalities. Statistical analysis revealed a significant reduction of the clinical parameters (BOPand PPD) in both groups at two, four, and six weeks when compared to the baseline. However, no significant differences have been found between the two groups throughout the study period. The outcomes are in agreement with some previous studies, and disagreement with others. In summary, non-surgical periodontal therapy is still considered the gold standard for periodontal treatment. Application of 660-nm diode laser is a non-invasive technique and no operative or postoperative complications have been reported by the subjects.

Published: February 2025

This research includes the development of a sensitive, swift and low-cost spectrophotometric procedure for estimating sulfadiazine in the form of pure substance and in its pharmaceutical dosage forms via condensation reaction. The method was involved the reaction of sulphadiazine with 4-dimethylaminobenzaldehyde in an acidic medium of HCl to produce a yellow soluble product has maximum absorption intensity at the wavelength 452 nm. The calibration graph was linear and compatible to Beer's low over the range of concentration 0.5 to 15ppm with a determination coefficient (r2= 0.9995) and molar absorptivity 2.90´104 l/mol.cm. The detection limit (DL), quantification limits (QL) and the sensitivity of Sandell were calculated and found to be 0.0543, 0.1810 µg/ml and 0.00860 μg/cm2, respectively. A relative error percentage and the relative standard deviation were calculated and found to be in the range -3.8% to 0.36% and ±0.33 to ±1.26%, respectively. The method has been successfully applied to assay sulfadiazine in burn cream and veterinary drugs (injection and powder).

Abstract: Two Rhodoliths bearing beds have been recognized in the Middle Miocene rocks of the Benghazi Formation at Al Jabal al Akhdar in Northeastern Libya. Three sections, the Daryanah-Abyar (DA) road cut and the Farkash Quarry in the vicinity of Daryanah village, and Majdoub Lake east of Benghazi city have been sampled and studied based on the faunal and floral (algal) evidences with integration of lithofacis characteristic in order to evaluate the environmental setting of Benghazi Formation at these locations. The repetition of Rhodoliths bearing beds is recognized twice in the Daryanah –Abyar (DA) road cut section and Farkash Quarry (FQ) section, whereas only once in Majdoub Lake section. The established Miocene units are spreadout in the range of ramp paleoenvironmental model. A lithological correlation has been built in to trace the lateral extension of the rhodoliths bearing-beds. The presence of the nodular rhodoliths below FWWB (i.e. >50 m water depth) indicates a proximal part of the middle ramp. Based on presence of Borelis melo and Miogypsinids the Benghazi Formation is dated as Miocene.

Published: February 2025

The arrangement of anterior teeth has a significant impact on the patient's looks, communication, and well-being. Maxillary prosthetic anterior teeth are put as close to their natural location as possible to maintain proper anatomophysiology.The purpose of this study was to assess the relationship between the placement of anterior teeth and the incisive papilla in dentate and then apply the findings to edentulous patients using linear regression analysis. 114 maxillary dentate casts were selected according to predetermined inclusion criteria. The antero-posterior length of the incisive papilla, the central and lateral incisors, and the intercanine line to the posterior limit of the incisive papilla were all measured directly on the casts. The Pearson correlation coefficient and linear regression analysis were used to verify the association and to develop linear regression equations to calculate the location of the anterior teeth depending on the length of the incisive papilla. The results showed that a significant positive linear relation was evident between the incisive papilla length and the horizontal distances that separated the incisive papilla from the central, lateral, and intercanine lines, respectively. As a result, three equations were formulated based on the linear model fit to calculate the horizontal placement of central, lateral incisors, and canine tips in an edentulous patient.
