The aim of this study is to demonstrate the effect of particle size on semiconductor properties; artificial intelligence is being used for the research methods. As a result, we picked cadmium sulfide (CdS), which is a unique semiconductor material that is employed in a broad variety of current applications. Given that CdS has distinct electrical and optical characteristics, it may be employed in the production of solar cells, for example. Solar cells, as is also well known, have become an essential source of energy in the world. Within the visible range (500-700 nm), we create one layer of bulk CdS and one layer of nano-CdS air bulk CdS air and air nano-CdS air. We used a number of instrumentation methods to investigate the naked CdS nanoparticles, including XRD, SEM-EDX, UV-Vis spectroscopy, TEM, XPS, and PL spectroscopy, among others. The results show that for bulk CdS at normal incidence, the transmittance is , and for nano-CdS with particle size 3 nm, the transmittance is , with transverse-electric (S-polarized) and transverse-magnetic (P-polarized) transmittances of and , respectively.

The purpose of this study was to evaluate the effect of palliative care intervention on the quality of life among Jordanian caregivers of cancer patients. Repeated measures design was used in this study. Data were collected from 137 Jordanian caregivers of cancer patients utilizing a self-administered questionnaire. An intervention program called SHARE was implemented to the experimental groups and its effectiveness in improving the overall quality of life for caregivers of cancer patients was evaluated using repeated measure ANOVA test. The results showed a statistically significant effect on the quality of life domains. For workshop experimental group (F = 26.822, p < .001) and for home visit experimental group (F = 10.236, p = .003).

Critically ill patients usually experience a significant level of pain during rest or during routine care such as turning, wound care, and endotracheal suctioning. Pain assessment is the cornerstone of pain management. Adequate pain assessment and management are major responsibilities of critical care nurses. The purpose of this study was to evaluate the nurses' knowledge, attitudes, and practices toward pain assessment and management of the intensive care unit (ICU) patients who are unable to communicate verbally. A descriptive cross-sectional design was used in this study. The study was conducted at ICUs in 5 hospitals from the north, middle, and south areas of Jordan. A self-administered questionnaire developed by Rose was used in this study. The most important finding in this study was that a large number of ICU nurses do not use assessment tools to evaluate the level of pain in patients who are unable to communicate verbally. Moreover, the nurses have inadequate knowledge about pain assessment and management. As perceived by the nurses, “restlessness” was the highest rated routine indicator of pain (25.1%), followed by “not following commands” (24%). Half of the participants (50%) answered that nurses were the persons who provide the most accurate rating of pain intensity. However, the participants showed positive attitude toward pain assessment and management.

Background: The critical conditions of intensive care patients require providing them with a higher acuity of care. Thus, it is essential to focus on critical care nurses and improve their work environment in a way that maximizes productivity, collaboration, satisfaction, and leads to improved patient care. Purpose: This study aims to explore the role the workplace layout design play in determining nurses’ satisfaction in three intensive care units (ICUs) at a university hospital. Method: A prospective, cross-sectional, single-center, survey-based design was employed in this study. Data were obtained, via a standardized questionnaire, from 36 morning shift nurses. The nurses’ self-reported satisfaction scores in three different ICUs with differing overall layouts, nursing station locations, and workplace design were statistically compared. Results: The study found that ICU 1 (private rooms, single corridor, central nursing station, close to supported services) had higher nursing satisfaction levels than ICUs 2 and 3 (open wards with separate service zones), F _(2,34) = 5.054, p = .012. However, overall satisfaction was higher with the ICU 2 primary workspace design, possibly due to the perceived acoustic privacy in this configuration, F _(2,34) = 4.492, p = .019. The ability of the ICU layout design to enhance teamwork and minimize traffic in patients care areas was found to be an important predictor of nurses’ satisfaction. The primary workspace design capacity to minimize congestion and the presence of large numbers of providers in a confined workplace might account for variation in nurses’ satisfaction. Conclusion: Physical environment variables in the ICU design may contribute to staff workplace satisfaction scores and may help in guiding informed choices regarding the future ICU design.
