Objective(s): Evaluation of late adulthood knowledge about social frailty, measure the level of knowledge about social frailty, and to find out the relationship between knowledge and socio-demographic characteristics. Methodology: A descriptive study design was carried out to measure the late adults' level of knowledge at Technical Institute-Suwaira in Middle Technical University and to find out the association between late adults' knowledge and their socio-demographic characteristic. The study was started from 28th April 2022 to 15th August 2022. The sample was Non-probability (convenience) sample of (100) late adults were selected according to the study that are working in Technical Institute-Suwaira. The data were collected by direct interview using specific questionnaire that’s composed of two parts (24) items which are: Part (1) Socio-demographic characteristics which included 9 items. Part (2) which deals with knowledge about social frailty and includes 15 items. Data were analyzed by using (SPSS) package version 25. Descriptive data through determination of: Frequency, percentage, mean of score and standard deviation. Inferential statistical data analysis approach: used by enforcement of the Chi –square test used for determining the association between Socio-demographic characteristics and late adults' knowledge. Results: (64%) of them were (49-56) years old, (61%) were male, the late adults' more than half evaluation of knowledge is moderate, more than half level of knowledge is moderate about social frailty (61%), and present high significant relationship between late adults' knowledge and age. Conclusions: The findings concluded that late adults need more awareness and information to support their knowledge about social frailty. Age, gender, job title, life style of late adults' socio-demographic characteristics that has a significant relationship with social frailty. Recommendations: The study recommend that need to developing educational programs, lectures, courses and seminars about frailty and domains of frailty to increase knowledge of late adults that lead to change their lifestyle and go away the wrong behaviors and habits.

“…If necessary, cut off filters were used to remove the contribution of second order emission due to scattering of excitation radiation. Datasets with steady-state spectra of anthrathiophenes and benzonaphthothiophenes are publicly available through the Gulf of Mexico Research Initiative Information & Data Cooperative (GRIIDC) [37][38][39].…”

The dispersion of harmful oil components into the ocean waters could pose long-term risks to flora and fauna. Due to the complexity of oil-contaminated sites, the unambiguous identification and quantitation of environmental pollutants often requires the sequence of high-performance liquid chromatography and gas chromatography-mass spectrometry. A classic example is the analysis of polycyclic aromatic hydrocarbons. This article tackles a different aspect of environmental analysis as it focuses on the Shpol'skii spectroscopy of polycyclic aromatic sulfur heterocycles, specifically those belonging to the subgroups often known as anthrathiophenes and benzonaphthothiophenes. Photoluminescence measurements were made with a commercial spectrofluorimeter equipped with a continuous wave excitation source for steady state measurements and a pulsed excitation source for time-resolved measurements in the phosphorescence time domain. To the extent of our literature search, this is the first report on the 4.2 K fluorescence and phosphorescence spectra of anthrathiophenes and benzonaphthothiophenes, and the 77 K and 4.2 K phosphorescence lifetimes of benzonaphthothiophenes. 77 K and 4.2 K analytical figures of merit revealed the possibility to detect the studied compounds at the parts-per-billion (ng mL −1) concentration levels. The spectral and lifetime data gathered in this article provides the required information to choose an appropriate photoluminescence technique for the analysis of four-ring polycyclic aromatic sulfur heterocycles in complex environmental extracts.

“…Synchronicity is affected by the great and the small perforations [1]. Stability is one of the necessary characteristics in the system and is divided into small signal stability and transient stability [2], [3]. To optimally allocate photovoltaic power based on distributed generations (PV-DG) the proposed hybrid particle swarm (PSO) has been applied to 33-bus and 69-bus [4]- [6].…”

Maintaining network synchronization is important to customer service. Low fluctuations cause voltage instability, non-synchronization in the power system or the problems in the electrical system disturbances, harmonics current and voltages inflation and contraction voltage. Proper tunning of the parameters of stabilizer is prime for validation of stabilizer. To overcome instability issues and get reinforcement found a lot of the techniques are developed to overcome instability problems and improve performance of power system. Genetic algorithm was applied to optimize parameters and suppress oscillation. The simulation of the robust composite capacitance system of an infinite single-machine bus was studied using MATLAB was used for optimization purpose. The critical time is an indication of the maximum possible time during which the error can pass in the system to obtain stability through the simulation. The effectiveness improvement has been shown in the system.
