Abstract:
... Frost damage during flowering is recognized as one of the most serious agro-meteorological disasters affecting apple production in Shaanxi province, a typical apple producing area in China. Quantitative assessments of flowering frost damage to apple yield are critical for the development of strategies on mitigating yield losses, but have been rarely conducted. For the first time, our study used th ...
... Hydrogels are widely used as sensors in the field of wearable devices. However, the hydrogels were rarely designed to endure the harsh outdoor environment in winter, including extremely low temperature, ultraviolet (UV) radiation and variable humidity. In addition, physical damage is also a challenge for hydrogels. In this study, a self-healing hydrogel with adhesion was prepared as a sensor for w ...

Abstract:
... PURPOSE: Deterioration of soil physical properties, especially poor soil structure, is the foremost cause for the low productivity of saline-alkali soils. The application of frost heaving in the soil has the potential to alter the physical properties of soils and subsequently affect the hydraulic characteristics of saline-alkali soils. However, insufficient research regarding their microscopic cha ...

Abstract:
... The method of freeze-thaw combined with vacuum pretreatment for landfill sludge (LS) has attracted extensive attention. However, most of the existing approaches are based on small-scale laboratory testing, and further testing studies must be performed to realize in situ treatment. To enhance the practicality of such approaches, the range of temperature effects on LS was analysed after field freeze ...

Abstract:
... The frequency and severity of spring frosts increase during the budburst in many regions of the world as global warming increases. Variability in the freezing resistance of sweet cherry flower organs during the active growing period has been rarely documented, especially in regard to the sepal, pedicel, receptacle, petal, stamen, and pistil organs of flower at the deacclimation stage. The freezing ...

Abstract:
... Discontent with one’s appearance (body image dissatisfaction) has become a global phenomenon, associated with the development of extreme behaviours in order to correct perceived body image problems. Much of the literature has focused on associated destructive behaviours that result from body image dissatisfaction; however, there has been a dearth of research examining risk factors for body image p ...

Abstract:
... A nonionic poly(oxyethylene) monoalkyl ether (C₁₂(EO)₆) and a cationic hexadecylpyridinium bromide (HPB) were used to achieve warm/cool transparency transition switchability, depending on the decrease in the hydration of the EO-headgroup of C₁₂(EO)₆ above the cloud point (Tc) and the crystallization of HPB below the Krafft point (Tₖ). The liquid state shows the advantage of being free-flowing, fro ...

Abstract:
... BACKGROUND: Spring frosts pose an important threat to orchard productivity in temperate zones and projections do not exclude damaging events in the future. However, there is no up-to-date and systematic comparison of the effectiveness and conditionality of the existing passive and active damage prevention strategies. This systematic review seeks to answer the questions “How do the performances of ...

Abstract:
... Austrocedrus chilensis is a South American conifer broadly distributed across the subtropical and extratropical Andes that is widely utilized in tree-ring studies. This species has clear annual growth rings that are sensitive to the moisture supply and has been extensively used to reconstruct the past hydroclimate during the last millennium. Despite a great number of dendrochronological studies ba ...

Abstract:
... Frost can cause irreversible damage to plant tissue and can significantly reduce yields and quality. A thorough understanding of the freezing dynamics is crucial to developing strategies for frost protection and the prevention of freezing damage. This study investigated artificial intelligence machine learning (ML) models to capture the thermodynamic patterns of freezing based on infrared thermogr ...

Abstract:
... The technology of hybrid breeding in diploid potatoes creates opportunities to design novel and improved cultivation systems based on hybrid true potato seeds. A promising cultivation pathway to produce seed or ware tubers is by transplanting greenhouse-raised seedlings into the field. This study explored the effects of transplanting date and seedling age on tuber yield, using greenhouse-raised se ...

Abstract:
... KEY MESSAGE: The flowering time of wild almond species studied herein is more influenced by heat requirement, which partly justifies also the differences in flowering date during the different years in genotypes. Bloom frost tolerance, chilling and heat requirements can influence distribution and productivity of almond species. Both laboratory and field-related methods were employed to determine t ...
... Sweet cherry (Prunus avium L.) is one of the economically important fruit crops worldwide. However, late spring frosts occurring in some years can significantly impact sweet cherry productivity through organ and tissue destruction caused by frost damage, and very little is known about frost tolerance or susceptibility of new cultivars. Differential thermal analysis (DTA) was, therefore, used to ex ...
... Global warming advances bud break, mismatches plant phenology from the local climate, and exposes the developing leaves to higher risks of frost damage. Bud break of sugar maple [Acer saccharum (Marsh.)], a species included in recent programs of assisted migration, is sensitive to nighttime spring temperatures. This suggests a link between frost events and leaf development. In this study, we raise ...

Abstract:
... Quercus protoroburoides Donchev and Bouzov ex Tashev and Tsavkov (Rila oak) is a species with extremely limited and localized distribution. It is found only on several locations on slopes above Rila Monastery in Rila Mountains (Bulgaria) at elevations between 1500 m and 1750 m a.s.l. The trees are in small groups or scattered, usually situated on ridges slightly higher than the local population of ...
... Cover crops provide agro-ecological services like erosion control, improvement of soil quality, reduction of nitrate leaching and weed control. Before planting the subsequent cash crop, cover crops need to be terminated with herbicides, mechanically or with the help of frost (winterkill). Winterkill termination is expected to increase its relevance in the next years, especially for organic farming ...
... Natural frost during stem elongation of winter wheat is one of the most destructive weather-related events in the Huang-Huai plain of China. Early prediction for yield loss helps to guide the timely implementation of a post-frost management strategy. Currently, frost stress indices calculated using the minimum Stevenson screen temperature (ST) only consider the effects of low temperature and durat ...

... Frost events incur substantial economic losses to farmers. These events could induce damage to plants and crops by damaging the cells. In this article, a recurrent neural network-based method, automating the frost prediction process, is proposed. The recurrent neural network-based models leveraged in this article include the standard recurrent neural network, long short-term memory, and gated recu ...

Abstract:
... We investigate the process of condensation frosting on flat surfaces using thermal imaging microscopy. This method is particularly well-suited to characterize the frosting of polydisperse assemblies of dew droplets, also called breath figures, that transform into ice droplets by the propagation of frost fronts. The front propagation speed is found to be a nonmonotonous function of the characterist ...

Abstract:
... Superhydrophobic surfaces with micron-nanosized two-tiered structures have huge potential in practical applications. However, the complex preparation process and low-stability of the versatile superhydrophobic surfaces restricted their wide application. Herein, a facile chemical etching process was applied to create a micron-sized rough structure on the 1060 aluminum alloy substrate, and the micro ...
