The current study centers on eliminating salt in the dyeing process of cotton products using reactive dyes. This study identified that the usage of reactive dyes is generating a huge amount of waste products that are contaminating the environment. Hence, this study introduces salt-free reactive dyes that can be used on cotton and would not contribute to ecological contamination. The prime purpose of this study was to explore a promising approach to reduce the cost of the dying process. Therefore, this study proposed the fiber modification technique based on chitosan and 1,2 dichloroethane as a proposed method for dying cotton, which will eventually help in reducing disposal and hazardous waste generated by saltbased chemicals. When the fabric is subjected to a treatment involving polyacrylamide, it causes cellulose to exhibit the main characteristics of wool. As a result, cotton can be dyed using reactive dyes under neutral pH conditions, without the need for electrolyte and alkali. Similarly, when fabric is treated with an emulsion of 1,2 dichloroethane followed by amination with sodium hydroxide, the treatment was discovered to enhance color fixation also. The modification was investigated through in-depth analysis in this research.
Worldviews on Evidence-Based Nursing
Background: When staffing legislation was introduced, New Jersey nurse leaders recognized from the research and their years of clinical leadership experience that the work environment is a multidimensional concept and that staffing is not the only variable related to nurse and patient outcomes. Thus, an understanding of what nurses need in their hospital environment to practice nursing effectively was sought. Aims: The aim of this study was to examine the evidence regarding clinical nurses' perception of what they need to practice nursing effectively in the acute care hospital environment. Methods: The following population, intervention, comparison, outcome question was used to search the literature databases PubMed, CINAHL, Johanna Briggs, and the Sigma Theta Tau Henderson Library: In the hospital environment what do nurses perceive as needed to practice nursing effectively? Specific search criteria and the Johns Hopkins nursing guidelines and tools were used to identify relative studies. Results: The final review, which addressed what nurses in the hospital environment need to practice nursing effectively, included 25 articles: 20 were an evidence level III, and five were evidence level II. From this review, five key concepts were identified: Leadership, autonomy/ decision making, respect/teamwork, resources/staffing, and organizational commitment to nursing. Linking Evidence to Action: This integrative review, which explored nurses' perceptions of what is needed to provide effective quality care, identified that providing quality care is multifactorial in nature. Resources, including but not limited to staffing, and leadership were identified as important by nurses as a key factor in supporting quality care. Nurses must be provided with resources and infrastructure to do their jobs, in an environment supported by authentic transformational leadership. BACKGROUND "What makes your hospital a good place for nurses to work?" This was the question posed to staff nurses and directors, in the seminal study from which American Nurses Credentialing Center (ANCC) Magnet ®-designated hospitals evolved, and continues to be contemplated by nurses and nurse leaders (McClure et al., 1983, p. 91). Due to growing concern about the nursing shortage in the late 1970s, which was exacerbated by nurse job dissatisfaction and poor nurse retention, a group of researchers investigated why some hospitals were better able to attract and retain nurses, acting like "magnets" for nurses, despite the nursing shortage (McClure et al., 1983). From this qualitative inquiry, it was discovered that these hospitals all shared a common set of organizational characteristics, which marked the beginning of nursing research focusing on nurse work environment. Since McClure et al.'s (1983) seminal work, much research has been conducted linking features of a positive nurse practice environment to better nurse and patient outcomes. In addition, organizations, such as the American Association of Critical-Care Nurses (AACN), have established standards for healthy work environments: skilled communication, true collaboration, effective decision making, appropriate staffing, meaningful recognition, and authentic leadership (AACN, 2005).

A partire da Freud che attribuiva la distruttività umana all’istinto di morte (Thanatos), psicoanalisti e psicologi hanno cercato di trovare determinanti genetiche o eventi ambientali come cause scatenanti dei comportamenti aggressivi. Intanto va detto che se l’aggressività ha svariate cause, nel comportamento umano molte sue manifestazioni provengono dalla rabbia. Tuttavia l’aggressività è un fenomeno più ampio che non la rabbia: essa non è necessariamente accompagnata da quest’ultima, e all’opposto la rabbia non porta necessariamente all’aggressione, specialmente negli individui adulti che possono più agevolmente controllare questo impulso. ....

Hasta su última edición publicada en 2012 por el autor del presente trabajo, la tradición textual de la Crónica de la población de Ávila consistía cuatro manuscritos, dos de ellos conservados en la Real Academia de la Historia y otros dos en la Biblioteca Nacional de Madrid. En un artículo publicado en 2008, Roberto Quirós Rosado menciona un quinto manuscrito, también conservado en la Biblioteca Nacional con la signatura mss/22026, al que llamaremos “E”. Este trabajo describe el texto tal como lo transmite E, vuelve a considerar la hipótesis de stemma codicum planteada previamente a la luz del nuevo códice, evalúa lecciones valiosas y ofrece el aparato completo de las variantes del nuevo testimonio
Sustainable Energy Technologies and Assessments, 2020
Ground source heat pump (GSHP) systems can provide cost effective and sustainable heating and cooling for buildings while using considerably less fossil fuel than conventional heating and cooling systems. This benefit can be further enhanced by adopting hybrid GSHP (HGSHP) systems wherein the GSHP component provides the baseload thermal energy with the balance provided by conventional systems. This study compares the costs of GSHP and HGSHP systems against conventional systems under a variety of climatic conditions, exemplified by those encountered across Australia, but including conditions encountered elsewhere. The results indicate that the comparative performance of GSHP and HGSHP systems depend on many parameters including climatic conditions, ground conditions, drilling prices and prices of electricity and gas in the regions where the systems are installed. Here we show that in general, adopting GSHP or HGSHP systems over conventional systems allow property owners to pay lower lifetime costs under most climatic conditions and gas to electricity energy price ratios. The results also indicate that conventional systems may be preferred in highly heating or cooling dominant climates and at locations with high drilling costs or low energy prices. In contrast, GSHP and HGSHP systems are preferred in locations with a more balanced climate, lower drilling costs and/or higher energy prices. There is no "one size fits all" rule given the many factors that can influence the lifetime costs. The paper shows that climatic conditions, ground conditions, drilling and energy costs must all be carefully considered when assessing the most cost effective sustainable energy technologies for space heating and cooling.
