LEARNING PREFERENCES AND VACCINATION STATUS OF STUDENTS IN A TERTIARY INSTITUTION: BASIS FOR FLEXIBLE LEARNING IMPLEMENTATION 2.0

The objective of this study is to determine the learning preferences and vaccination status of students from a local college in Olongapo City, Philippines. The investigators employed a descriptive-survey research among 5,021 students who were currently enrolled in the academic year of 2021-2022.  Results show that 94.7% prefer online mode of learning; 79.7% show intention to enroll for the next semester of the new academic year; however only 51.7% of the students wanted a face-to-face class and 61.4% of the students’ parents/guardian approve their son/daughter to attend face-to-face classes. In terms of vaccination status, 95.3% of the students have their vaccinations shots already (fully vaccinated) and Pfizer was the brand of choice of the 38% students. The study concluded that students are still prefer online mode of learning. Also, majority of the students were fully vaccinated. The study recommends continue and enhance the implementation of flexible learning of the institution

PROGRESS IN 2 mm GLOW DISCHARGE POLYMER MANDREL DEVELOPMENT FOR NIF

OAK-B135 All planned National Ignition Facility (NIF) capsule targets except machined beryllium require a glow discharge polymer (GDP) mandrel upon which the albator is applied. This mandrel, {approx} 2 mm in diameter, must at least meet if not exceed the symmetry and surface finish requirements of the final capsule. Such mandrels are currently produced by the three-step depolymerizable mandrel technique. The quality of the final mandrel depends upon precise optimization and execution of each of the three steps. They had shown previously that fabrication of a mandrel which met the symmetry and surface finish requirements was feasible using this technique. In this paper they will discuss recent progress towards converting this process into a high yield, production scale process

Hydrodynamic Issues in PAMS Mandrel Target Fabrication

OAK-B135 Imperfections in PAMS mandrels critically govern the quality of final ICF targets. Imperfections in the mandrels can have a wide range of origins. Here, they present observations of 3 types of imperfections, and data to support the proposal that hydrodynamic factors during the curing of the mandrel are potential causes of these imperfections

FABRICATION AND PROPERTIES OF OER COATED RESORCINOL-FORMALDEHYDE SHELLS FOR OMEGA EXPERIMENTS

OAK-B135 New high gain designs for direct drive ignition on NIF require foam shells. Scaled down versions of these designs are needed for near term experiments on the OMEGA laser facility at the Laboratory Laser Energetics (LLE). These shells need to be about 1 mm in diameter and 50-100 {micro}m wall thickness and densities of 100-250 mg/cc. In addition, a full density permeation seal needs to be deposited for retention of the fill gas at room temperature or the ice at cryogenic temperatures. They have fabricated such shells using Resorcinol-formaldehyde (R/F) as the selected foam material due to its transparency in the optical region. Extensive characterization of the wall uniformity of these shells has been performed. The foam shells have {approx} 5%-6% non-concentricities on the average. A full density permeation seal has been deposited on the R/F shells using two different techniques. In the first technique R/F shells are coated directly with plasma polymer to thicknesses of 3-4 {micro}m. In the second technique, R/F shells are coated with polyvinylphenol, using a chemical interfacial polymerization technique. Data on surface finish and gas retention for R/F shells coated by both methods are provided

Lawson criterion for ignition exceeded in an inertial fusion experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion

Budget Allocation System of a Highly Urbanized Local Government Unit in Central Luzon, Philippines

The study determined the local planning and budget process of a highly urbanized local government unit (LGU) in Central Luzon, Philippines. It involves all department concerns and civil society organizations (CSOs) that use the City's local governance performance management system (LGPMS). The researchers used a descriptive research study to obtain the necessary data from a survey to seventy-five (75) rank and file employees. The researchers used a purposive sampling technique to gather the respondents involved in planning, budgeting, and managing programs and projects. With a self-made instrument that underwent validity, the researchers gathered the essential data for the study. The data were statistically analyzed using frequency, percentage distribution, analysis of variance (ANOVA), and t-test for independent variables. Preliminary results illustrated that respondents' status was in regular status as division head level, and their years of service were more than sixteen (16) years. The statistical analyses revealed no significant variations in the assessment on the budget allocation system of the local government unit (LGU) as determined on its indicators. The management also agrees that employees work effectively in the budget allocation of the local government unit. The study recommended the orientation and assessment on the current allocation and budget process wherein the department's prioritization can review the objectives and policy decisions
