This research analyses the operation of a solar PV powered electric vehicle charging station with energy storage, that has been developed and demonstrated at the University of California--Davis, West Village, the largest planned zero-energy consumption community in the U.S. The intelligent energy management approach introduces solar PV electrical energy forecasting and EV （electric vehicle） charging demand projection to optimize the SOC （state of charge） of the buffer battery. The charging station has been operated continuously and routinely used by several EV users for a year. The actual operation shows that, a workplace charging station equipped with a buffer battery and with intelligent energy management can lower and reduce the station＇s peak power demand, and reduce the energy exchange with the utility grid by a factor of 2. The battery recharging power demand was shifted away from the on-peak time periods to the off-peak time periods, which will benefit the charging station owner from less energy use during peak periods when time-of-use rates are higher. The standard cell voltage deviation of the 220 cells was calculated to analyse the battery cell consistency during the resting, charging and discharging periods. The analysis shows that, the 220 50Ah cells show excellent voltage consistency with voltage deviation of less than 0.005 V within the battery SOC of 20%-80%. The voltage deviation doubles when the battery SOC reaches 90%. The comparison of cell voltage deviation at the beginning and after one year operation indicates that, the battery shows perfect cell voltage consistency and there is no obvious consistency deterioration during the battery resting, charging and discharging periods.

Background: The authors have developed criteria utilizing the mnemonic “SPEEDS” (saturation, pain, extremity movement, emesis, dialogue, stable vitals signs) to evaluate and predict which patients would not require phase I nursing intervention and could transition to phase II recovery. Methods: Seventy-three adult surgery patients underwent a standardized general anesthetic. Patients were evaluated with the modified Aldrete, Fast-Track and SPEEDS criteria immediately before leaving the OR and then 5, 10, 15 and 30 minutes after arrival in the recovery area. Results: Significantly more patients met phase I bypass criteria when evaluated with Modified Aldrete (90%) and Fast-Track (94%) as compared to SPEEDS (77%) (p 0.0429 modified Aldrete vs. SPEEDS, p 0.0038 Fast-Track vs. SPEEDS). However, SPEEDS was more sensitive having a lower number of patients meeting phase II criteria yet requiring phase I intervention (32%) vs. Fast-track (43%) and Modified Aldrete (44%) (p 0.001 SPEEDS vs. modified Aldrete and Fast-Track). SPEEDS was more accurate (74%) in predicting which patients should move directly to phase II compared to modified Aldrete (42%) (p 0.001) and Fast-track (59%) (p = 0.05). Conclusion: SPEEDS criteria are as specific and more sensitive in determining phase I nursing interventions for ambulatory surgery patients when compared to Fast-Track and modified Aldrete criteria.

Enzyme adaptations to temperature occur constantly as temperature patterns modulate diurnally and seasonally. These adaptations entail qualitative and/or quantitative metabolic changes that often provide a competitive advantage, impact adjustment to new environments, and effect the survival of the species. Changes in isozymes or allozymes, changes in enzyme concentration, modification by substrate and effectors, and metabolic regulation of enzyme function without changing enzyme composition are all possible strategies for adaptation to changes in temperature. The degree of adaptation among cotton cultivars to a specific thermal regime may be difficult to determine from phenotypic responses of the plants. The present study evaluated the thermal sensitivity of Gossypium hirsutum L. and Gossypium barbadense L. cultivars following growth under distinct thermal environments. The metabolic fitness of Gossypium hirsutum L. and Gossypium barbadense L. cultivars showed that the Gossypium hirsutum L. cultivars grown in a 28°C/20°C day/night cycle tended to be better equipped to cope with a 16 h - 38°C treatment than the same cultivars grown in a 38°C/32°C day/night cycle. The Gossypium barbadense L. cultivars, on the other hand, grown in a 38°C/32°C day/night cycle tended to be equipped to cope with a 16 h - 38°C treatment than the same cultivars grown in a 28°C/20°C day/night cycle. The Gossypium hirsutum L. line TX 303 is an exception to these general trends as its responses were similar to the Gossypium barbadense L. St. Vincent and Pima S-7 cottons.

Our aim is to determine the cause(s) of migraine auras. Our understanding of how migraines and migraine auras originate is very imperfect. An important observation is that migraines occur more frequently in women at reproductive age than in men at a similar age. This suggests that gonadal hormones may be relevant triggers. The occurrence of classical (typical auras without headache) auras in one author (WB) has been recorded. Every aura in six years (85) has been noted, studied and analysed statistically. The auras occur predominantly in Spring and Autumn, especially in the longer reproductive season of Spring. This association is supported statistically. The results support the idea of gonadal hormones as relevant triggers, the strongest candidate being estrogen. Basic mechanisms underlying the auras are discussed, especially the phenomenon of cortical spreading depression. We also propose that both auras and migraines depend upon previous injury to the head or to the brain, giving rise to a condition of “deafferentation hypersensitivity”.
