Opis:
Today most teachers enter teaching by means of a one or two-year undergraduate program in education (B.Ed.). There is provision of in-service training for teachers to make teaching effective in bringing quality to education. Various in-service teacher training programs are organized by District Institutes of Educational Training and State Institute of Educational Management and Training under Sarva Shiksha Abhiyaan in Himachal Pradesh. Yet, the impact of the training has not been reflected in the classrooms for the last fifteen years. There is not optimum improvement in the academic achievement of students. It is necessary to make teaching enjoyable and flexible through various activities, small projects and ICT in the new era. Creative and experimental activities are very much needed in the teaching of mathematics and science subjects. These activities help in building student confidence and give students more opportunities of learning. ‘PRAYAS’ at the upper-primary level is one of the programs organized by the DIET Solan to professionally prepare in-service teachers for implementing it at the school level. The objective of the study was to study the impact of the ‘PRAYAS’ in-service training program in Science in the educational block Kandaghat block of district Solan of Himachal Pradesh. Three schools were conveniently selected, two Govt. Senior Secondary Schools Chail and Kalhog, and one Govt. High School, Sakori, of the concerned educational block. Data was collected with the use of a semi-structured interview and the observations were recorded. It was found in the study that students made models and activities on the topics of their textbooks under the ‘PRAYAS’ program with eco-friendly materials and waste materials, utilized where suited. In this way, students learnt to use waste materials in everyday life. The models and activities were very low cost and easy to handle and care. The students learnt and understood the concepts easily. The outcomes of the program are discussed in the paper, which will be beneficial for the educational planners and administrators and in-service teachers of the State.

Opis:
An all-optical vestigial sideband carrier suppressed return-to-zero to non-return-to-zero format conversion is presented with the help of simulation using cross-phase modulation in a nonlinear dispersion shifted fiber. For comparative analysis, a semiconductor optical amplifier based conversion is also considered. Through the process of spectral filtering, the wavelength converted output signal is recovered from a broadened optical spectrum. Error-free conversion of vestigial sideband carrier suppressed return-to-zero pulses to non-return-to-zero format is presented at 10 Gb/s using a 210 − 1 bit sequence and is able to transmit the recovered data through a distance of 50 km having a power penalty of around 1.38 dB in the case of dispersion shifted fiber, whereas a semiconductor optical amplifier performs abysmally.

Opis:
We know that oxygen therapy plays one of the important role for treating hypoxemia and it is widely used across a whole range of specialties and it involves administration of oxygen at concentrations greater than that in ambient air. We are reporting the first case of twisting of reservoir bag on using non-rebreathing face mask for providing supplemental oxygen in awake prone position in a 60 year old male tested COVID-19 positive. To prevent this twisting we recommend if a manufacturer do slight modification in making of these non-breathing face mask by adding a 1-2 cm L- shaped Plastic connector to the neck end of the oxygen reservoir bag. The sudden deflation of these reservoir bag not only increase the dead space, decrease alveolar ventilation but substantially compromised the gas exchange. So any twisting of these non-rebreathing face mask should be avoided. This twisting may compromise the patient condition due to rapid increase in PaCO2 and detrimental in patients with restrictive airway disease. On keeping the patient in prone position the twisting of the reservoir bag frequently occurs and this simple and useful modification may be beneficial for supplementation of oxygen therapy to COVID-19 patients requiring high fractional inspired oxygen concentration.

Opis:
A novice advanced architecture of 8-bit analog to digital converter is introduced and analyzed in this paper. The structure of proposed ADC is based on the sub-ranging ADC architecture in which a 4-bit resolution flash-ADC is utilized. The proposed ADC architecture is designed by employing a comparator which is equipped with common mode current feedback and gain boosting technique (CMFD-GB) and a residue amplifier. The proposed 8 bits ADC structure can achieve the speed of 140 mega-samples per second. The proposed ADC architecture is designed at a resolution of 8 bits at 10 MHz sampling frequency. DNL and INL values of the proposed design are -0.94/1.22 and -1.19/1.19 respectively. The ADC design dissipates a power of 1.24 mW with the conversion speed of 0.98 ns. The magnitude of SFDR and SNR from the simulations at Nyquist input is 39.77 and 35.62 decibel respectively. Simulations are performed on a SPICE based tool in 90 nm CMOS technology. The comparison shows better performance for this proposed ADC design in comparison to other ADC architectures regarding speed, resolution and power consumption.

Opis:
Being a biodegradable polymer, poly(lactic acid) (PLA) based composites receive greater preference over nonbiodegradable plastics. Poly(lactic acid) has to find its place in various applications such as polymer composites, agriculture, biomedical, etc. Polymer composites based on PLA possess comparable mechanical strength, endurance, flexibility and endures future opportunities. Several combinations of natural fibers and filler-based PLA composites have been fabricated and investigated for physical and mechanical changes. Moreover, several biopolymers and compatibilizers are added to PLA to provide rigidity. The paper presents a tabulated review of the various natural fiber/filter-based PLA composites and the preparation and outcomes. In addition, enhancement made by the reinforcement of nano filler in the PLA are also discussed in brief. The significance of PLA in the biomedical application has been discussed in brief. The paper also shed lights in the social and economic aspects of PLA.

Opis:
In post-pandemic India the recovery in tourism has become known as ‘revenge’ meaning revenge on the disease. It is tourism due to the desperation to travel, especially in the current scenario in which those who have been confined to their homes have grown tired of being trapped there. The restless mood caused by the ongoing pandemic reached its peak and it is possible that this will eventually help in bringing back a rapid return to tourism. To analyze the travel intentions of potential tourists after the current pandemic ends, an attempt has been made to make an analysis of tourism in India to find out how Covid-19 is impacting on people’s lives and how willing they are to participate in tourism again.
W Indiach po złagodzeniu długotrwałych obostrzeń pandemicznych zaobserwowano zjawisko odradzania się podróżowania, znane pod nazwą turystyki zemsty (ang. revange tourism), traktowanej jako szczególny odwet na chorobie. Obserwowana dzisiaj potrzeba podróżowania wynika z desperackiej chęci odreagowania poczucia zmęczenia i uwięzienia we własnych domach. Niepokój wywołany pandemią osiągnął apogeum i możliwe jest, że przyczyni się do wznowienia ruchu turystycznego. W celu przeanalizowania intencji potencjalnych podróżnych podjęto próbę zbadania branży turystycznej w Indiach pod kątem wpływu COVID-19 na życie ludzi i ich chęci ponownego udziału w turystyce.

Opis:
Abeliophyllum distichum Nakai, an ornamental plant, contains a wide range of phytochemicals having pharmaceutical properties. The use of different plant-based extracts for the enhancement of yield and/or quality of soybean sprouts, one of the most inexpensive but nutritious food products, is common. The objective of this study was to examine the effect of A. distichum flower extract (ADE) on the yield and nutritional value of soybean sprouts. Soybean seeds were soaked in ADE solutions with concentrations (w/v) of 0.5% (ADE-0.5), 1% (ADE-1), 3% (ADE-3), and 5% (ADE-5). The effect of ADE concentration on the yield and different nutrient components varied. The highest soybean sprout yield and vitamin C content were found with ADE-3. The most abundant essential amino acid content was detected in ADE-1, whereas the greatest amounts of total isoflavones and total minerals were determined in ADE-5 and the ADE-untreated control, respectively. Overall results of yield, color, and contents of vitamin C, amino acids, and isoflavones suggest that 1% or 3% of A. distichum extract could be an optimum concentration to soak the soybean seeds for higher sprout yield and nutrient content.

Opis:
Herbal extract-induced metallic nanoparticles have replaced the traditionally synthesized nanoparticles to achieve sustainability in antimicrobial textiles. Silver nanoparticles (NPs) were created by the bio-reducion of silver nitrate with eucalyptus corymbia leaf extract. The bi-lateral activities of herbal extract, like the reduction and capping of silver nanoparticles, have added new dimensions in the bactericidal sector. Silver nanoparticles were characterized by UV-visible spectroscopy, a particle size analyzer, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) and X-ray diffractometry. In this study these biosynthesized nanoparticles were applied on cotton fabric alone and along with chitosan by the pad-dry-cure method to create antibacterial clothing. Antibacterial efficiency was characterized using the colony counting method (serial dilution method). The treated fabric shows excellent antibacterial efficiency.

Opis:
Designing a finite impulse response (FIR) filter with minimal group delay has proven to be a difficult task. Many research studies have focused on reducing pass band and stop band ripples in FIR filter design, often overlooking the optimization of group delay. While some works have considered group delay reduction, their approaches were not optimal. Consequently, the achievement of an optimal design for a filter with a low group delay value still remains a challenge. In this work, a modified differential search optimization algorithm has been used for the purpose of designing a minimal group delay FIR filter. The results obtained have been compared with the classical techniques and they turned out to be promising.
