“…Several studies included the assessment of nutritional intake and/or nutritional status of hospitalized aged people as a central topic [16] as well as nutritional assessment and risk factors for malnutrition [14], assessment of nutritional intake in longer-lived older adults [40], assessment of nutritional status and use of handgrip strength as a marker of nutritional risk [27], in addition to assessing the effects of poor appetite on the health outcomes [26].…”

“…Nutritional status can be assessed by handgrip strength in hospitalized patients [27]. Nutritional support guided by repeated energy balance measurements leads to better outcomes after hip fracture surgery, as there is a lower cumulative energy balance (−1229.9 ± 1763 versus −4975.5 ± 4368 kcal, p = 0.001) and a lower total complication rate (27.3% versus 64.3%, p = 0.012) [20].…”

Objective: to search in the current literature the elements that exert an influence on feeding and nutrition in hospitalized aged people. Method: the following strategies were used for the integrative review stages: research question (Population or Patients; Exposure; Outcomes); analysis flowchart (Preferred Reporting Items for Systematic Reviews and Meta-analyses); and levels of evidence corresponding to the studies (Oxford Centre for Evidence-Based Medicine). The searches were conducted in the MEDLINE/PubMed, Biblioteca Virtual em Saúde, Embase, CINAHL and Scopus databases. Results: the initial search yielded 1808 studies, of which 34 comprised the analysis corpus after applying the inclusion/exclusion criteria. The assessments corresponding to nutritional status and to the risk factors for hospitalized aged people are fundamental in defining the diet. An association was found between inadequate energy intake, lack of appetite, infections, malignity, delirium and need for assistance in feeding. Dysphagia affected nutritional status and was associated with multimorbidities, cognitive impairment, malnutrition, higher dependence for the activities of daily living, and greater care need. Nutritional support improved the perioperative nutritional status, in addition to reducing the hospitalization times and the number of infectious complications. Conclusion: the main disorder that hinders meeting the nutritional needs is dysphagia, and is associated with aged people's multimorbidity and dependence. The results provide geriatric and gerontological knowledge about elderly nutrition, in addition to targeting preventive and intervention treatments and care during hospitalization.

“…In contrast, high-dose irradiation leads to more radiation damage, increasing the number of non-radiative recombination centers and thus reducing the luminescence efficiency. The decrease in the intensity of the near-band-edge emission peak is attributed to the creation of nitrogen vacancies following ion irradiation [11,12], although the position of the near-band-edge peak remains unchanged. The nonradiative recombination centers associated with high-energy radiation-induced defects lead to the observed changes in the PL spectra [13].…”

The irradiation influences the properties of GaN. We studied the irradiation of n-type, p-type, and i-type GaN with 2.9865GeV Ta ions, with experimental irradiation fluence of 3×108, 3×109, and 2×1010 cm-2, respectively. Low fluence ion irradiation of GaN enhances the luminescence performance of the samples and releases stress between GaN and the sapphire substrate. We have proved that this is due to the displacement of Ga or N atoms repairing the defects caused by the entry of irradiated ions, thus enhancing the performance of GaN. This provides a reference for low fluence irradiation of GaN.

“…The deconvoluted outputs of the original biexponential pulses need to be processed through pulse shaping, which can effectively reduce the electronic noise and increase the signal-to-noise ratio (SNR) [8,9]. Traditional pulse shaping methods include quasi-Gaussian, triangle, trapezoid, cusp-like, 1/f and so on [10][11][12][13]. Trapezoids have been extensively applied in pulse shaping by virtue of their excellent energy resolution, so we adopted a trapezoidal shaper.…”
