Abstract
In this paper, we have derived certain classical inequalities, namely Young’s, Hölder’s, Minkowski’s and the Hermite–Hadamard inequalities for a pseudo-integral (also known as g-integral). For Young’s, Hölder’s and Minkowski’s inequalities, the cases

, have been covered. Moreover, in the case of the Hermite–Hadamard inequality, the refinement has also been proved
and, as a special case, a g-analogue of a geometric-logarithmic-arithmetic inequality has been deduced.
On a boundary-domain integral equation system for the Robin problem for the diffusion equation in non-homogeneous media
Authors: Fresneda-Portillo Carlos 
Published: March 2022

Abstract
The Robin problem for the diffusion equation in non-homogeneous media partial differential equation is reduced to a system of direct segregated parametrix-based Boundary-Domain Integral Equations (BDIEs). We use a parametrix different from the one applied by Chkadua, Mikhailov, Natroshvili.
in [4].
We prove the equivalence between the original BVP and the corresponding BDIE system. The invertibility and Fredholm properties of the boundary-domain integral operators are also analysed.

Published: March 2022

AbstractWe describe an experimental and theoretical study of the mechanisms of flow of rubber compounds in a screw extruder. Two compounds, a typical synthetic rubber (butadiene-styrene copolymer-cis-1, 4 polybutadiene) based passenger tire tread (PTT) and a natural rubber based truck tire tread (TTT), were investigated in a 112${}^{1}/{}_{2}$inch NRM cold feed screw extruder using a screw with a constant channel depth and constant channel pitch along the whole screw length. The rubber was cured in place and the screw removed. The screw exhibited starvation behavior except near the die. The length of the rubber strip in the screw is proportional to the pressure developed at the die. Marker studies showed transverse circulating flows beginning in the region immediately downstream from the hopper. These observations indicate that cold feed extruders exhibit a metering region flow, albeit sometimes starved, from entry port to die. Under these conditions the extruder is independent of the pressure developed in the screw channel. A simple non-Newtonian isothermal mathematical model for the metering zone is described. The rubber compound is considered as a pseudoplastic material with a yield value. A comparison of theory and experiment shows that a one dimensional isothermal model quite accurately predicts the flow rate pressure development of the rubber compound in our screw (with a shallow prismatic channel) when starvation is considered. The yield value of the rubber compound influences screw characteristic curves only for very high values of the dimensionless pressure gradient.
Development of a Novel Transcription Molding Process to Fabricate Sophisticated Polymer Products with Precise Microstructure and High Transparency Applicable to Display Devices and Bio-chips

Published: March 2022

Abstract
In this study, we developed a novel transcription-molding process and experimentally discussed its validity for fabricating polymer products having the precise microstructure on the surface. The process was named “Melt-Transcription Process” which consists of two characteristic stages; coating and compression. In the coating stage, a molten polymer is coated on the surface of a metal mold having the precise microstructure by a coating device specially designed in this study. The thickness of the coated polymer melt is typically 100 μm or more. Immediately after coating, the coated polymer is compressed against the mold surface so as to make the polymer flow into the microstructure cavities engraved on the mold, and to fabricate the 3-dimensional structure of polymer products. The pressure required for compression is quite lower than that in conventional nano-imprinting process, because the molten polymer of high temperature is distributed in advance over the mold surface in the coating stage.
The “Melt-Transcription Process” was applied to fabricate polymer products with the size of 150 mm in length, 150 mm in width and 1 mm in thickness, having the microstructure of tens micrometers on their surface. Cyclo-olefin polymer (COP) and Polymethyl methacrylate (PMMA) were used as the polymer materials, and the dimensions and transcription ratios (the ratio of the height of the transcribed microstructure to the depth of the microstructure on the mold) of the molded microstructure were experimentally evaluated. As a result, by the Melt-Transcription Process, the microstructure was sufficiently transcribed on a very thin substrate of large surface area with high transcription ratios, typically 95% or more, under relatively low compression pressure of less than 10 MPa.
The process was also applied for fabricating products with a range of thicknesses and we could experimentally verify that products composed of a membrane of 80 μm thickness and a surrounding frame with 1.95 mm thickness were successfully molded. Furthermore, we fabricated a micro-lens array product by using film grade PMMA with relatively higher viscosity in a product having 125 μm in thickness and a size of 102 mm × 102 mm.

Nietzsche: Culture Warrior or a Sign of the Times?
Authors: Bishop Paul 
Published: March 2022

AbstractA century and a half after theKulturkampfin Germany, and three decades after James Davison Hunter’s account of the “culture warriors,” this book review examines what Nietzsche might have to say to us today about our understanding of the past and our relation to the future. It considers two studies of the four essays of Nietzsche’sUnzeitgemässe Betrachtungentaken as a whole, one study of Nietzsche’s second essay on history, one on Nietzsche’s general conception of decadence and culture, and a collection of essays on Nietzsche’s views of history and memory. Taken together, these studies not only complement (rather than contradict) each other in respect of their readings of theUnzeitgemässe Betrachtungenand the question of culture, they also throw light on other aspects of Nietzsche by reminding us of the rootedness of Nietzsche’s thought in the outlook of Weimar classicism and highlighting the vitalist aspects of Nietzsche’s thought. The review concludes that Nietzsche is more timely than ever, not least because of his critique of education, as well as his attention to such key themes as identity politics,Erinnerungskultur, and museumization; it is still possible to agree with Nietzsche’s sentiments as expressed in a motto from an early notebook of July 1862: “I prefer the past to the present; but I believe in a better future.”

Abstract

Matricaria aurea (Loefl.) Schultz Bip. (Asteraceae), known as golden chamomile, has been traditionally used for the treatment of various diseases. In this study, total phenolic, flavonoid, and tannin contents of total extract and different fractions of this plant were determined. The antioxidant, cytotoxic, and antimicrobial activities were also evaluated. Moreover, the phenolic profiles of selected fractions were determined by HPLC and LC-MS/MS analysis. Results demonstrated total phenolic contents of 37.8–57.2 mg GAE/g and total flavonoid contents of 3.0–111.2 mg QE/g. The ethyl acetate and methanol fractions (EF and MF) had the highest concentrations of phenolic, tannin, and flavonoid compounds. In both DPPH radical scavenging assay and phosphomolybdenum reduction assay, EF showed the best antioxidant activity, followed by MF. EF and MF indicated also the best antibacterial activities against Bacillus subtilis (MIC 1.56 and 12.5 mg ml−1) and Staphylococcus aureus (MIC 0.78 and 12.5 mg ml−1). Hexane fraction (HF) had no antibacterial effect. None of the samples had antifungal effect. MTT (3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay revealed for EF and HF the highest antiproliferative activities (IC50 values ranged from 111.8 to 294.6 μg ml−1). The presence of chlorogenic acid, ferulic acid, and luteolin-7-O-glucoside in MF, and p-coumaric acid in EF was confirmed and quantified.

Abstract

Artemia urumiana is bisexual population of the Lake Urmia of Iran. Its biomass was freeze dried and using its lyophilized powder, hydro-alcoholic extract was prepared and utilized in gold nanoparticles (Au NPs) synthesis. Six different Au NPs fabrication methods namely: microwave heating, hydrothermal, ultraviolet (UV) irradiation, ultrasonication, common heating using conventional heating, and self-assembling were utilized for Au NPs synthesis using A. urumiana extract. Gas chromatography analysis indicated that the prepared extract were contained numerous fatty acid methyl esters such as Hexadecanoic acid methyl ester. Results indicated that the formed NPs using heater and stirrer, and UV irradiation had minimum particle size of 25 and 94 nm, respectively. However, as compared to the formed Au NPs using heater and stirrer technique, UV irradiation fabricated Au NPs with high zeta potential value of −32.5 mV and small polydispersity value of 0.310. Results also demonstrated that the synthesized Au NPs using heater and stirrers, and UV irradiation had highest antioxidant activities of 13.7 and 11.9%, and bactericidal effects against Escherichia coli and Staphylococcus aurous bacteria strains, as compared to other fabricated Au NPs using other methods. There were insignificant (p > 0.05) differences between these two attributes of the formed Au NPs.

Published: March 2022

The ability to comprehend phrases is an essential integrative property of the brain. Here, we evaluate the neural processes that enable the transition from single-word processing to a minimal compositional scheme. Previous research has reported conflicting timing effects of composition, and disagreement persists with respect to inferior frontal and posterior temporal contributions. To address these issues, 19 patients (10 male, 9 female) implanted with penetrating depth or surface subdural intracranial electrodes, heard auditory recordings of adjective-noun, pseudoword-noun, and adjective-pseudoword phrases and judged whether the phrase matched a picture. Stimulus-dependent alterations in broadband gamma activity, low-frequency power, and phase-locking values across the language-dominant left hemisphere were derived. This revealed a mosaic located on the lower bank of the posterior superior temporal sulcus (pSTS), in which closely neighboring cortical sites displayed exclusive sensitivity to either lexicality or phrase structure, but not both. Distinct timings were found for effects of phrase composition (210–300 ms) and pseudoword processing (∼300–700 ms), and these were localized to neighboring electrodes in pSTS. The pars triangularis and temporal pole encoded anticipation of composition in broadband low frequencies, and both regions exhibited greater functional connectivity with pSTS during phrase composition. Our results suggest that the pSTS is a highly specialized region composed of sparsely interwoven heterogeneous constituents that encodes both lower and higher level linguistic features. This hub in pSTS for minimal phrase processing may form the neural basis for the human-specific computational capacity for forming hierarchically organized linguistic structures.SIGNIFICANCE STATEMENTLinguists have claimed that the integration of multiple words into a phrase demands a computational procedure distinct from single-word processing. Here, we provide intracranial recordings from a large patient cohort, with high spatiotemporal resolution, to track the cortical dynamics of phrase composition. Epileptic patients volunteered to participate in a task in which they listened to phrases (red boat), word-pseudoword or pseudoword-word pairs (e.g., red fulg). At the onset of the second word in phrases, greater broadband high gamma activity was found in posterior superior temporal sulcus in electrodes that exclusively indexed phrasal meaning and not lexical meaning. These results provide direct, high-resolution signatures of minimal phrase composition in humans, a potentially species-specific computational capacity.

Published: March 2022

BackgroundGenetically determined hearing loss (HL) can be inherited in two major ways - autosomal recessive or dominant. Autosomal dominant hearing loss (ADHL) is usually postlingual and progressive. To date, 50 different genes have been demonstrated to be causally involved in its development. In Polish ADHL patients, TBC1D24 pathogenic variants are a frequent cause of the disease.Case reportA three-generation Polish family with ADHL was recruited for the study. An audiological assessment was conducted and next- generation sequencing of a custom HL multigene panel (n = 237 genes) was performed in the index patient. The presence and segregation of the detected variant with HL was verified by Sanger sequencing. All affected individuals had postlingual progressive HL, mainly affecting high frequencies. In this study, a very rare previously reported p.Ser178Leu variant in TBC1D24 was identified in all family members with HL.ConclusionsOur study provides an independent confirmation of the pathogenic role of TBC1D24 p.Ser178Leu in HL. In individuals with ADHL-related TBC1D24 pathogenic variants, the cochlear component of the auditory system is affected. Patients may also report tinnitus but usually do not complain of vertigo

This study was conducted to get the data and information about the target organ that might help in creating better understating of the physiological mechanism of this organ in Zovawk.For this experiment 6 apparently healthy pigs were selected. Different physical parameters of the collected samples were measured. To know the cellular architecture collected pancreas samples were first fixed with 10% NBF and were subsequently processed with standard tissue processing technique. For ultra-sturctural studies tissues were stained with Lead citrate and uranyl acetate. B cells were more numerous than the A cells in the islets of Langerhans which is characterized by the spherical nucleus and located almost all over the islets. Whereas A cells were characterized by the oval nucleus and distributed mainly in the center of the islets. Numerous zymogen granules were present in the acinar cells of zovawk pancreas which are thought to be the reason for the higher enzymatic properties in the zovawk pancreas.

Smoking affects cardiovascular system by different mechanisms. Smoking related diseases are the biggest killers in the world today. Cardiac output is increased by nicotine which is present in smoke by increasing both heart rate and myocardial contractility. Our aim was to compare and assess resting heart rate in smoker and nonsmoker healthy males. Our objective was to study the effect of smoking on resting heart rate. We included total 60 male subjects in the age group 25 – 65 years comprising of 30 smokers as case group and 30 nonsmoker healthy males as control group for present study and these were relatives of patients, sweepers, peons and paramedical staff of P.D.U. Govt. Medical College. Pulse Oximeter was used to measure resting heart rate immediately after over night sleep. Heart rate was recorded in a condition of physical and mental rest. Data was tabulated and analysed. By using Z test, P value was found which was statistically significant (&#60;0.05). Resting heart rate is important parameter to measure the effect of smoking on cardiovascular system. Smoking related products are dangerous to health and causes many health related diseases. From our study, we conclude that the resting heart rate of apparently healthy smokers is significantly higher than nonsmokers of same group.
