For four seasons, individual buds developing on sultana vines in the field were shaded with a number of materials during the period of floral initiation. Heavy shading up to complete darkening consistently reduced the number and size of inflorescence primordia. This reduced fruitfulness could not be related to changes in the spectral quality of the light, which might have upset the phytochrome system, nor to changes in temperature of the buds.

Commonly used image fusion techniques generally produce good results for images obtained from the same sensor, with a standard ratio of spatial resolution (1:4). However, an atypical high ratio of resolution reduces the effectiveness of fusion methods resulting in a decrease in the spectral or spatial quality of the sharpened image. An important issue is the development of a method that allows for maintaining simultaneous high spatial and spectral quality. The authors propose to strengthen the pan-sharpening methods through prior modification of the panchromatic image. Local statistics of the differences between the original panchromatic image and the intensity of the multispectral image are used to detect spatial details. The Euler’s number and the distance of each pixel from the nearest pixel classified as a spatial detail determine the weight of the information collected from each integrated image. The research was carried out for several pan-sharpening methods and for data sets with different levels of spectral matching. The proposed solution allows for a greater improvement in the quality of spectral fusion, while being able to identify the same spatial details for most pan-sharpening methods and is mainly dedicated to Intensity-Hue-Saturation based methods for which the following improvements in spectral quality were achieved: about 30% for the urbanized area and about 15% for the non-urbanized area.

There are an increasing number of people living with dementia in care home settings. Recent reports suggest that people who deliver care to residents living with dementia in care homes require specialist support to provide optimum care. To address this need Four Seasons Health Care, the largest provider of care homes within the UK today, sought to design a dementia care framework that enhanced the quality of life for people living with dementia in their care homes. The framework was designed using a robust evidence base, engagement with people living with dementia, their care partners, policy-writers, multidisciplinary professionals and people within the organisation. This paper describes the methodology behind the dementia care framework and outcomes data from the first phase (of 20 care homes that included the care of 451 people living with dementia). The main outcome was a significant improvement in the quality of the lives of residents across biological, psychological, social and spiritual needs.

Vertical distribution of species and infraspecies taxa of diatoms (Bacillariophyta) on well mosses where they live epiphytically, and a relative number of individuals per surface area unit were followed in 8 open wells with shadoof. Researches were conducted during 2015-2016 through four seasons. Sampling of algae material from well mosses that cover interior of the well was conducted on every 50 cm of depth starting from the surface (O cm) to 200 cm. Considering the specificity of substrate on which diatoms live in wells, and those are mosses that are especially expressed to 1,5 m depth of well and whose leafs cover each other and have an effect on light climate of micro habitat with already existing differences in intensity and quality of light, relative humidity of air, temperature of air on different depths, density of populations of certain species Bacillariophyta is in function of such ecological occasions on different well depths. It is concluded that the most abundant populations on mosses of researched wells, during most of the year, develop four aerophilic species of diatoms: Navicula contenta Grunow, N. atomus var. atomus (Kiitzing) Grunow, Achnanthes lanceolata (Brebisson) Grunow ssp. lanceolata var. lanceolata and Amphora normanii Rabenhorst.

The Valdivia River estuary (VRE) located in south-central Chile is known as one of the largest estuarine ecosystems on the Pacific coast. This research aims to determine the intra-tidal and sub-tidal variability of saline intrusions into the VRE between November 2017 and March 2019 derived from salinity sensors located along the VRE. Complementary hydrographic measurements were conducted during flood and ebb conditions of the spring and neap tides for each of the four seasons of the year along the central axis of the VRE. The results of the salinity time series showed that saline intrusions (values greater than 0.5 Practical Salinity Units) occurred ~20 km from the estuary mouth, when the total flow of the Cruces and Calle-Calle rivers (main tributaries of the estuary) was low, around 280–300 m3 s−1. During the same period, the best co-variability was observed between the saline intrusions and the mixed-semidiurnal tide and the fortnightly and monthly periods of the tide. Regression analyses indicated that salinity intrusion length (L) is best correlated to discharge (D) with a fractional power model L α D−1/2.64 (R2 = 0.88). The decreasing discharge trend, found between 2008–2019, implies that saline water intrusions would negatively impact the Valdivia’s main drinking water intake during the low rainfall season under future climate conditions.
