Practice teaching is one of the ways in order for teacher education students to become prepared for the real battle in the field of teaching and learning. This study was conducted in order to determine the significant difference in the practice teaching experiences of preservice teachers of DNSC when analyzed according to their major and school where they were assigned. Particularly it aimed to assess the level of practice teaching experiences of preservice teachers of DNSC. The study used descriptive research design. The respondents were the preservice teachers of DNSC from 2017-2018. An adaptive research questionnaire was used and data were treated using mean and ANOVA. The result of the study revealed that the level of practice teaching was manifested often times. The study posited that there was no significant difference in the level of practice teaching experience when analyzed according to their major but significantly different when analyzed according to school assigned. It is revealed that those who were assigned in Sto. Tomas National High School had different experience from La Filipina National High School, Nieves Villarica National High School, and Panabo National High School this may be due to school distance, social problem, student behaviors, instructional media and support, working place and task, and nature of school. The study will be the basis for crafting practice teaching module and further investigation on what specific experience made the preservice teachers differ from each other especially in the school where they are assigned.

When Higher Education Institutions shifted to online learning due to COVID-19 student satisfaction significantly dropped. This study aimed to identify the learning experiences of students in online learning, ascertain the level of student satisfaction, and determine the significant difference in the level of student satisfaction in online learning. A quantitative non-experimental design was used as research design in which a stratified random sampling was employed to determine the 278 students to become the respondents and adaptive questionnaire was used to gather the data needed for the study. Percentage, mean, and ANOVA were used to statistically treat the gathered data. The study revealed that majority of the respondents had an access to electricity, television. This further showed that most of the respondents did not own a radio and internet connection. The study confirmed that students used Mobile Data to attend online classes and majority of them uses Smartphone. In terms of the learning modality, the study revealed that Modular Approach was most used learning modality in online learning. The study confirmed that all of the faculty were using DNSC LMS, Google Classroom. During the synchronous online learning, the instructor used Google Meet during online classes and Facebook Messenger during the asynchronous learning. This study concluded that the level of satisfaction with online learning do not vary significantly when analysed according to status of internet connectivity, type of internet connection, devices used in flexible learning, and digital technologies used during synchronous flexible learning. The study concluded that there is a significant difference in the level of student satisfaction with online learning when analysed according to learning modality used in flexible learning and digital technologies used during the asynchronous flexible learning. Therefore, the use of both online learning and modular learning, and the use of other digital technologies like Facebook Messenger is highly encouraged to increase the level of student satisfaction with online learning.

Fossil fuels formed through millions of years is a limited resource as well as the increase of energy usage in the industrialized world accelerate the rapid depletion of fossil fuel, which is not renewable and is associated with pollution problems. Therefore, using renewable energy is a key solution to the problem of fossil fuel depletion. There are several resources of renewable energy like geothermal energy, solar energy, and biofuels. Biodiesel is a fatty acid alkyl ester made from renewable resources such as used cooking oil, and algae. The attractiveness of biodiesel lies in the reduction of the dependency on imported petroleum in non-oil-producing countries and the provision of a market for excess production of vegetable oils in mainly agricultural countries. Biodiesel is produced from its feedstock through the transesterification reaction that was done using methanol as an alcohol and potassium hydroxide as a catalyst. The aim of study is to identify the effect of methanol amount and catalyst concentration on the biodiesel yield. The properties of the produced biodiesel were comparable with ASTM standards.

The ongoing pandemic (COVID-19) caused by SARS-CoV-2 has massively affected the global economies. Pakistan reported the second-highest COVID-19 cases within South Asian countries, the fifth-highest number of verified cases in Asian states after Iran, India, Russia, and Saudi Arabia and the 14th highest recorded cases worldwide. The pandemic’s peak witnessed confirm 6,825 cases in a single day on June 13; however, the trend went downward with a significant decrease registering new patients. Pakistan reported a 95.3% recovery rate with 317,595 confirmed cases, with a fatality rate of 2.12%, recorded deaths 6,552, significantly lower than the global average 3.6%. The COVID-19 has resulted in over 36.8 million cases, deaths over 1.675 million, and recovery of 27.697 million people from this infectious disease worldwide, as of October 9, 2020. The pandemic adversely struck the Pakistan economy. The GPD reflected a negative growth first time over the last 60 years, which caused the massive financial crisis. The Government’s relief package intervened to reduce public mental stress and assisted to improve quality of their life.

Background: Sufficient hemodialysis adequacy is one of the main goals of treating patients with hemodialysis. It is one of the fundamental causes of a decrease in the quality of life. Exercise is one of the complementary methods that can potentially be effective in improving hemodialysis adequacy. This study investigated exercise\'s effect on hemodialysis\'s adequacy by using minibikes. It focused on examining patients undergoing hemodialysis treatment.\nMethods: This present study recruited 96 patients through randomized clinical trials from the two largest hemodialysis centers associated with Shafa and Javad-al-Aimeh Hospitals. The study selected 54 samples based on the inclusion criteria and randomly assigned patients to the intervention (n = 27) and control (n = 27) groups. Based on inclusion criteria, the study further included thirty-seven hemodialysis patients then randomly divided them into the intervention (n = 20) and control (n = 17) groups. The participants of the intervention group exercised with mini-bikes for 20 minutes twice a week for three months. The investigators measured Hemodialysis adequacy {clearance creatinine * time/volume (K t/V) and Urea Ratio Reduction (URR)} in the first, second, and third months during the intervention and one month after the intervention.\nResults: The results showed that there was no significant difference between the two groups in terms of Kt/V mean (p>0.05). Besides, there was no significant difference between the two groups in terms of URR mean (p>0.05).\nConclusion: Exercise with a minibike did not affect the hemodialysis adequacy of patients. Further studies on this field are required. The results of this study provide insightful information for further research on the impact of exercise during hemodialysis on other laboratory results.

Salinity is one of the worldwide limiting factors in decreasing crop production. Seed is primitive part which exposed to salinity and get problem in germination. Seed germination indicators were investigated for early selection of salinity tolerant wheat genotypes. Salinity treatments (0, 50mM, 100mM and 150mM) were given to 125 genotypes, sown in CRD with replication. All genotypes were found significant for germination speed index (GSI), time required for germination of 50% seeds (T50), mean germination time (MGT), mean germination rate (MGR), variance of germination time (VGT), coefficient of variation of germination time (CVt), germination speed coefficient (CVG), and non-significant for final germination percentage (FGP), time required for germination of 90% seeds (T90), germination synchrony (Sync) and uncertainty (Unc). Salinity treatments are significant for all seed germination indicators except uncertainty (Unc). FGP had positive correlation with GSI, MGT, T50, T90, Sync, Unc and negative correlation with CVG, MGR, CVt. MGR has negative correlation with all indicators except CVt. Based on germination indicator and salt tolerant index, 11 genotypes were found tolerant, 38 moderates tolerant, 48 moderate susceptible and 28 susceptible. Results suggested important parameters to select salinity tolerant plants at seed germination stage, which help in salt-tolerance breeding program.
