Authors: Srivastava Ms Akansha
Published: August 2022

Abstract: For the creation of composite materials based on high density polyethylene, silica nanoparticles are utilised as fillers. Due to their low cost, high aspect ratio, and rather acceptable mechanical qualities, silica nanoparticles are recommended for reinforcement of high density polyethylene and may be found in a variety of sources. Compression moulding and a stirrer were used to prepare the composite. Tensile and Impact tests are used to examine the composite's mechanical characteristics. ThermoGravimetric Analysis (TGA) and Differential Scanning Calorimetry are used to assess the composite's thermal characteristics (DSC). The results of the composite's testing show that adding silica nanoparticle reinforcement has enhanced the mechanical and thermal characteristics of the HDPE composite

Published: August 2022

Abstract: The Robot i.e. Sylvester firstly follow the human throughits sensors then spread the awareness message through its speaker tell them to take mask hand sanitizer from its back by just putting their hand in front of the hand sanitizer tells them to grab the black part (situated on its neck) by two fingers according to your body temper- ature; it allows you to enter/depart to/from the place. Again, it can do so, after completion of the task which ismentioned above. It’s especially useful in crowded areaslike Market Places, Shopping Malls where there are lots of people. If we place such type of robot in the Shopping Malls, then there is no need to appoint a person for that kind of work at the entrance of the malls by sim- ply holding a hand sanitizer thermal scanner. This type of robot is totally helpful in that field, instead of a human.

Aim. To evaluate the safety and accuracy of percutaneous transhepatic biliary biopsy in patients with suspected Klatskin tumor.

Materials and methods. Between 2013–2020, percutaneous transhepatic biliary drainage (PTBD) was performed in 52 patients with Klatskin tumor, complicated by obstructive jaundice. After successful PTBD, the diagnosis was verified by antegrade access. 74 procedures were performed: brush (n = 36; 48.6 %) or forceps biopsies (n = 38; 51.4 %).

Results. There were no adverse events associated with a brush biopsy. Only grade I complications were after the forceps technique: 3 patients (7.9 %) developed hemobilia, which was corrected conservatively. Malignant lesions of the biliary tract were detected by forceps technique in 79.0 %, brush biopsy in 66.7 % (p >0,05). The degree of tumor differentiation was determined in 60.0 % (n = 18) vs 12.5 % (n = 3) (p < 0,01), respectively.

Sensitivity and specificity of forceps biopsy were slightly higher than in brush: 82.4 % and 75.0 % vs 73.3 % and 66.7 % (p >0,05).

Conclusions. Antegrade percutaneous transhepatic biliary biopsy is safe for both brush and forceps techniques. However, forceps biopsy has higher sensitivity and specificity in the diagnosis Klatskin tumor and better possibility of determining the degree of malignancy differentiation.

Aim. To evaluate the antitoxic activity of chicory herb extract fractions in rats with toxic hepatitis.

Materials and methods. There were 64 male rats were divided into groups of 6 animals that received the whole chicory herb extract, its fractions, or the reference drug (RD) and 2 groups did not receive any drug. The Silimar substance (a dry purified extract obtained from the fruits of milk thistle [Silybum marianum]) was chosen as RD. Animals from one of the groups that did not receive the drug (control group) and the groups that received drugs were injected with CCl4 to simulate toxic liver damage. The last group of animals received neither drugs nor CCl4 (intact animals). The changes in the activity of biotransformation enzymes (cytochrome P450 [cytР450] and glutathione transferase [GT]) in hepatocytes and serum liver enzymes (AST, ALT and AP) were assessed.

Results. There was a decrease in cytР450 and GT activity in the liver microsomes of control rats (having CCl4 hepatitis without treatment) compared with intact animals. These parameters were more in the animals that were administrated with chicory herb extract, its fractions, and RD than in control animals. The administration of the whole extract, aqueous fraction, and RD led to an increase in the activity of cytP450 and GT enzymes almost to the level of the same indicators in intact animals. Pronounced grown in the activity of serum liver enzymes (ALT, AST and AP) were found after CCl4 injection. Administration of common chicory herb fractions before toxic liver damage caused a decrease in the grown of the activity of these enzymes. The greatest inhibitory effect on the grown of the activity of these liver enzymes had RD, aqueous and butanolic fractions of chicory herb. Despite a significant decrease in hyperfermentemia found in groups of animals treated with fractions of chicory herb, AST, ALT and AP activities did not reach the level that was in the intact animal group.

Conclusion. The aqueous and butanolic fractions of the chicory herb extract had the highest antitoxic activity in experimental animal toxic liver injury.

Published: August 2022

We developed a solid formulation of calcium alginate beads containing paclitaxel-loaded lipid-core nanocapsules (PTX-LNC-Bead) intended for oral administration. The PTX-LNC liquid formulation was prepared by interfacial deposition and trapped into calcium alginate beads. These beads were characterized in terms of size, morphology, swelling rate, encapsulation efficiency, and release of PTX and LNC in simulated gastrointestinal fluids. Results showed that the beads were gastro-resistant with low swelling rate and drug release lower than 3.5% at pH 1.2 (2h). At pH 6.8, the beads showed high swelling rate and disintegration after 80 min. Drug release was 60% after 600 min. Particle sizing as a function of time confirmed that LNC were released intact from the beads at pH 6.8 showing that PTX-LNC-Bead is a promising product for PTX oral administration. Our results pave the way for novel formulations intended for drug targeting by the oral route.

Efonidipine Hydrochloride Ethanolate and Chlorthalidone is used in management of hypertension and under clinical phase 3 study. The development of quality control method is required for accurate analysis of both drugs. Two simple, precise and economical UV spectrophotometric methods have been developed for the simultaneous estimation of Efonidipine Hydrochloride Ethanolate and Chlorthalidone in their synthetic mixture. Method I is simultaneous equation method (Vierodt’s Method), which is based on measurement of absorption at 251 and 227 nm i.e. λmax of Efonidipine Hydrochloride Ethanolate and Chlorthalidone, respectively. Method II is first order derivative was based on the measurement of absorbance of Efonidipine Hydrochloride Ethanolate measure at 283.2 nm (ZCP of Chlorthalidone) and absorbance of Chlorthalidone measure at 250.8 nm (ZCP of Efonidipine Hydrochloride Ethanolate). Linearity was observed in the concentration range of 6.4-38.4 µg.mL-1 for Efonidipine hydrochloride ethanolate and 2-12 µg.mL-1  for Chlorthalidone using methanol as a solvent. The accuracy of methods was assessed by recovery studies and was found to be within range of 98-102% for both the drugs. Precision of the methods was estimated by repeatability and intermediate precision studies. The % RSD values were found to be less than 2, proving methods were precise. Two methods were compared using F- test. The results were validated statistically as per ICH Q2 R1 guideline and were found to be satisfactory.

One of the requirements for mining cryptocurrency (Crypto) is that the secured ledger of the blockchain must be updated. However, updating the secured ledger requires that the miner develop and solve complex mathematical equations in higher orders hexadecimal 64-digit solution called a hash. In addition to this challenge, the mining processes of cryptocurrency are both resource and cost-intensive. The resources required include, but not limited to mining software, hardware, power (energy usage), CPU or compute cycles, and NP-hard problem. Apart from these numerous challenges that are associated with mining cryptocurrency, the amount of speed that is required to mine a single block is core. Cryptocurrency mining speed requirement is significantly important because only miners that can have the fastest mining device are most likely to get the reward (profit) from competing for a block. In this paper, we designed and implemented a model to speed up mining process which is capable of giving miners an advantage to arrive at a block earlier. The novelty of our architecture is that our design is based on high performance computing paradigm where we achieve processor speed up by parallelizing the number of processors p. We experimented by varying p = 4, 8, 16. Our experimental results where we used the MC6800 simulated on Easy68k emulator demonstrate feasibility of our proposed model and prove that speed was an essential key to cryptocurrency mining.

Published: August 2022

The objective of the paper was to analyse the selected factors that influence the size of the demand for organic products in the contexts of modernization or designing new highly effective distri-bution channels. The research was performed by means of a questionnaire in the form of a guided survey on 50 respondents living in the south part of Poland. The obtained results are a source of precious knowledge particularly for producers of organic products who want to reach as many final purchasers as possible. The place of living and level of education of potential customers were found to be the most important criteria which should be considered when designing or modernizing distribution channels. The amount of monthly income does not affect considerably the size and frequency and the place of where organic products are purchased. Adjusting the existing distribution channels to customers' re-quirements will allow companies to achieve success in the form of high profits and strengthen their market position.

Published: August 2022

This article examines the effects of uncertainty shocks such as the one posed by the current Covid-19 pandemic on global airline transport with a particular focus on the European region, including Poland. The rationale behind the topic choice is that air transport, mainly passenger one, belongs to those economic sectors that are most affected by the global pandemic due to lockdowns of economies, travel restrictions set up by countries around the world, and people reluctance or fear to travel. As the pandemic situation is still changing, the previous assessments of the Covid-19 impacts available in literature require continuous updating. In this respect, using the most up-to-date data, the current paper contributes to a growing body of knowledge by focusing on such aspects as changes in air traffic volume, passenger and cargo, the financial condition of air transport providers, and this industry employment. The article is of a descriptive character. It is based on the scientific and popular literature, and publicly available Eurostat and Statista statistics as well as aviation industry-specific sources (ICAO, Eurocontrol, IATA, ATAG). The research adopts the methodological approach proper for a positive economics. The results indicate that not the entire aviation sector was negatively affected by Covid-19, as freight and private non-commercial aviation transport increased sharply during the pandemic.

Authors: Fr. Baiju Thomas
Published: August 2022

The current study focuses on using information communication and technology (ICT) in English teaching-learning for students with special educational needs (SwSENs) in an inclusive classroom setting. In ensuring the most effective methods of English Teaching-Learning, it is vital to examine pedagogical approaches. Globalization has led to a more entangled interaction between the digital and physical worlds. Our increased reliance has significantly impacted our daily lives on technological devices. Thus, it stands to reason that SwSEN is becoming constantly excited about using ICT in the teaching-learning process in inclusive classrooms. Every modern culture that can survive relies on ICT. This will impact education and other aspects of one's life. Students of English who don't speak the language natively now have easy access to many resources because of its technology. In the meantime, many higher education institutions cannot function efficiently without the help of ICTs. ICT enhances the teaching-learning process. Use it to expose students to new learning opportunities. Teaching-learning English has been reinvigorated by using ICT in the inclusive classroom. ICT is essential for ensuring that SwSENs access high-quality English language learning opportunities. As an outcome of the study, new strategies for teaching-learning English in inclusive settings may be developed. Today's global society demands that the teaching-learning of English as a second language adapt and evolve. This study highlights the positive benefits of ICT on SwSENs in an inclusive classroom setting to keep up with today's technologically sophisticated society. In this context, the function of ICT in English language teaching-learning will be examined. Teaching English as an additional language is concerted and coordinated to the ever-changing demands of a technologically advanced society. Whether or not ICT can enhance English language teaching and learning has been debated for several centuries. ICT is being actively adopted in today's academic institutions, particularly those offering English language programs for SwSENs in an inclusive classroom setting. ICT is increasingly being used to teach English as a Second Language in academic institutions. Having such environments in place for both teaching-learning must be investigated if we are to determine how ICT is being used for SwSEN in an inclusive classroom setting.
