Agriculture is threatened by ever increasing temperatures and this trend predicted to continue for the near distant future. The negative impact of rising on agri-food systems also compounded erratic highly variable rainfall in most parts southern Africa. Minimum maximum temperatures’ variability analysis were undertaken using daily time series data derived from 23 meteorological stations spread...

As a consequence of the growing concern about warming of the Arctic Ocean, this study quantified the thermal acclimation responses of Boreogadus saida, a key Arctic food web fish. Physiological rates for cardio-respiratory functions as well as critical maximum temperature (Tc,max) for loss of equilibrium (LOE) were measured. The transition temperatures for these events (LOE, the rate of oxygen ...

Determination of temperature requirements for many economically important insects is a cornerstone of pest management. For bark beetles (Coleoptera: Curculionidae, Scolytinae), this information can facilitate timing of management strategies. Our goals were to determine temperature predictors for flight initiation of three species of Ips bark beetles, five species of Dendroctonus bark beetles, a...

The present study is about the analysis of mean, mean maximum and mean minimum temperatures carried out on annual, seasonal and monthly time-scales examining the data from 8 meteorological stations in Istanbul for the period 1975-2006. Various spatial and statistical tools were used to display and analyze trends in temperature data. ArcGIS was used to produce the spatially distributed temperatu...

Maximum water temperatures in streams throughout the western USA typically occur in late summer and early autumn, coinciding with low stream flow. However, in the spring-fed Big Springs Creek in northern California, where constant-temperature groundwater springs provide relatively stable stream flow throughout the year, peak water temperatures and maximum diurnal variability occur in spring. We...

In this study, the performance of permeation tube (PT) devices for the generation of VOC calibration gas was examined by successively generating BTX gas at five temperatures (30, 50, 70, 80, and 100 °C) and two flow rates (400 and 800 mL min⁻¹). A distinct relationship was observed between temperatures and permeation rates (PR) (or generated BTX concentrations). We examined the reliability of t...

OBJECTIVES The habitual consumption of extremely hot foods and beverages may affect implant treatment modality. Our objectives were to: (i) establish the maximum temperature produced intra-orally while consuming very hot substances and (ii) use these values in an ex vivo model to assess the temperature changes along the implant-bone interface. MATERIALS AND METHODS Temperatures were measured ...

We investigate the thermal conductivity of liquid water using computer simulations of the TIP5P model of water. Our simulations show that, in addition to the maximum at high temperatures at constant pressure that it exhibits in experiments, the thermal conductivity also displays a minimum at low temperatures. We find that the temperature of minimum thermal conductivity in supercooled liquid wat...

Effects of the pathogenic fungus Melampsorella caryophyllacearum on radial growth of Abies alba Long-term damages caused by fungi on tree radial-growth and its interaction with climate have been little studied. The incidence and the severity of damage caused by the pathogenic fungus Melampsorella caryophyllacearum on Abies alba in three plots sampled in the Irati forest (Western Pyrenees, Navar...
