Aim of this study to examine the mediating role of network service between perceived quality, retailer service and customer satisfaction during COVID-19. Primary data gathered through adopted questionnaire from previous studies and 200 university students were asked to fill online questionnaire during COVID-19 situation in country. Structural Equation Modelling technique applied in order to test the proposed hypothesis generated from existing literature review. Findings revealed full mediation effect of network service for both perceived quality and retailer service on customer satisfaction during COVID-19. New insights of this study are key role of network services is identified and university students' satisfaction is measured for online classes in developing country, Pakistan. In future serial mediation is suggested for validity of existing results in developed and developing countries.

The production performance of multiparous lactating Sahiwal cows (n = 24) was evaluated according to both milking frequency and method. Selected animals were randomly divided into four groups containing six animals each under a completely randomized design. Cows in groups A & B were milked by the hand milking method three times per day, respectively. Similarly, cows in groups C & D were milked by the machine milking method two and three times per day, respectively. All animals were maintained under uniform feeding and management conditions. Dry matter intake was high in animal groups milked three times per day, and it remained unchanged between the hand and machine milking methods. Milk yield was higher (P < 0.05) in cows milked three times compared to those milked twice per day, and it did not differ between hand and machine milking methods. Milk fat percentage was higher (P < 0.05) in cows milked twice per day compared to those milked three times using both machine and hand milking methods. The percentage of total solids showed a similar pattern as the fat percentage. However, percentages of protein, lactose, and non-fat solids in milk were not significantly different(P > 0.05) among the treatment groups. Collectively, the results show that milking three times per day instead of twice at 8-hour intervals can enhance milk yield in Sahiwal cows using both hand and machine milking methods.

With the growing overdependence on the widely available Global Navigation Satellite System (GNSS) technology, the demand of the secure, reliable and accurate navigation especially for the aviation market has been a major concern of the satellite navigation engineers. The ionospheric scintillation is one of the most dangerous and sophisticated phenomena that not only compromises the accuracy of the receiver’s position, velocity and time (PVT) output but also the reliability of receiver’s performance in such critical situations. The maximum intensity scintillation occurs after every 11 years on average and, therefore, due to lack of available data, there are not enough practical studies to study this phenomenon. In this paper, we study the strong scintillation data collected during the last strong solar maximum event in 2013 at the Ascension Island. The frequency-to-frequency correlation is selected as an important metric to study the fading signals. The observations and the results discussed in the paper are the significant contributions toward the practical study of real ionospheric scintillation data and, hence, provide a strong ground for the future research.

The objectives of the research are to explored the heat and mass transport over a paraboloid surface of revolution by taking the effects of Lorentz force, resistive heating and internal heat source. The dimensionless version of the model was attained via similarity transformations. Then, for solution purpose, RK scheme is utilized and performed computations for the flow fields. The influence of different physical quantities on the flow characteristics described comprehensively via graphs. It is examined that the stretching index parameter m opposes the fluid velocity and the temperature enhances for Eckert number. Moreover, significant impacts of the Schmidt number are observed for mass transfer gradient.

<P><B>Abstract</B></P><P>Breast cancer is the most common cancer diagnosed among women. In this article, support vector machine is used to classify digital mammogram images into malignant and benign. Wiener filter is used to handle the possible quantum noise, which is more likely to occur in mammograms. Stack‐based connected component method is proposed for background removal, and the image is enhanced using retinax method. Seeded region growing algorithm is used to remove the pectoral muscle part of the mammogram. We have extracted 13 different multidomains' features for classification. Results show the superiority of the proposed algorithm in terms of sensitivity, specificity, and accuracy. We have used MIAS database of mammography for experimentation. Microsc. Res.

The recovery of solvents from the extracted oils using conventional thermal separation processes i.e. distillation or evaporation is often an energy-intensive process. To provide an energy-efficient alternative, an organic solvent nanofiltration thin-film composite membrane was prepared by depositing a thin layer of polyaniline (PANI), a selective layer, via interfacial polymerization on a crosslinked polyimide (XPI), a base ultrafiltration support membrane, to provide selective transport of constituents of a miscella. The membrane was characterized by microscopic, spectroscopic, and thermal analysis. The evaluation of the separation performance was carried out by a dead-end stirred cell using three vegetable oils. For sunflower, corn, and castor oil/n-hexane mixtures, the membrane resulted in a % rejection of 50, 56, and -44, respectively. A comparison of mass flux and rejection of corn and castor oils suggests that the PANI/XPI membranes showed a strong ion-exchange behavior significantly recognizing charge macromolecules due to the presence of charged emeraldine PANI.

Quartz tuning forks (QTFs) are being more frequently adopted instead of micromachined cantilevers as force sensors in scanning probe microscopes due to their mechanical stability, high quality factors, and wide availability at low costs. Mass-produced QTFs are typically housed in vacuumsealed canisters, and this necessitates the removal of the vacuum canisters to make necessary modifications such as attaching a tip or an optical fiber. Commonly, the decrease in the quality factor after the removal of the canister is attributed to an increase in air damping with no further investigation of other possible causes. We carried out several experiments with QTFs before and after the canisters were removed. Despite a vacuum level below 10−5 Torr, all investigated QTFs exhibited decreased quality factors once the protective canisters had been removed. We present possible causes for this observation by analyzing optical microscope images. Also, complete mechanical and electrical characterizations of the QTFs are presented, taking advantage of the analogies that exist between mechanical and electrical systems.
