The Leadership in Energy and Environmental Design (LEED) rating system has been widely used in the US. However, until now, there has been no clear understanding of the strategies that should be used to make the transition from Silver to Gold certified projects. The aim of this study was to determine the trends in certified projects for both Silver and Gold LEED for New Construction and Major Renovations (LEED-NCv3) in 2016. Three performances, including (i) certification, (ii) category/subcategory/sub-subcategory certification, and (iii) cross-certification, were evaluated for both Silver and Gold LEED-NCv3 certified projects. For an ordinal measurement scale, a two-tailed Mann-Whitney U test was used. For a ratio measurement scale, an unpaired two-tailed t-test was used. If eight or more Silver and Gold certified projects occurred in the same state, then the state was selected for statistical analysis. As a result, ten states were selected. The following was revealed: (i) low certification performances for both Silver and Gold;(ii) high category performance for Sustainable Sites and Innovation in Design and low category performance for Energy and Atmosphere for both Silver and Gold projects;and (iii) three different strategies of certified projects in transition from Silver to Gold that include (a) energy-emphasized (e.g., CA), (b) non-energy-emphasized (e.g., NY), and (c) integrated (e.g., GA) strategies. We speculate that the possible reasons for such deviations in the decision strategies were due to differences between the adopted ASHRAE 90.1 standards (ASHRAE Standard 90.1 2007 or ASHRAE Standard 90.1 2010) in each of the states.

Leadership in Energy and Environmental Design Commercial Interiors (LEED-CI) is more relevant to interior design, which, according to the sharing layer concept, differs from exterior design (which is usually evaluated with the LEED New Construction sub-scheme). LEED-CI requires separate empirical analyses of LEED-CI certified buildings to further improve this sub-scheme. Therefore, in this study, Silver and Gold projects certified under LEED-CI-2009 in 14 US states were considered. Three project performance analyses, (i) certification, (ii) category, and (iii) cross-certification, were studied. The following results were revealed: (i) the range of the medians for Silver- and Gold-certified projects were 51-57 pts and 62-71 pts, respectively;(ii) in both Silver- and Gold-certified projects, Sustainable Sites (SS), Water Efficiency (WE), and Innovation in Design (ID) were the best-performing;Energy and Atmosphere (EA) and Indoor Environmental Quality (EQ) were intermediate-performing;and Material and Resources (MR) was the worst-performing categories;and (iii) in Silver-Gold cross-certification, category-focused (in 10 of 14 states) and category-unfocused (in four of 14 states) strategies were determined;in the category-focused strategy, the highest popular category was EA;the intermediate popular categories were WE, MR, and ID;and the lowest popular category was SS. Pooling all projects and all states into one frame can lead to the obscurement of the actual LEED-CI-2009 strategy(ies) in the transition from Silver to Gold certification in the US.

This study aims to evaluate the Silver-to-Gold LEED-NC 2009 (Leadership in Energy and Environmental Design for New Construction and Major Renovations) cross-certification performance and categorize the cross-certification performance in eight US states in 2012-2017. The following three statistical analyses were used: (a) pooling LEED projects within a single state and single year in a single-state-year group with the subsequent use of a replication method, (b) pooling the medians of the LEED projects in each state from all years in a state-and-total-years group, and (c) pooling the LEED projects from all states and years in a total states-and-years group. The Silver-to-Gold cross-certification performance has a low propelling effect. Considering the Silver-to-Gold category cross-certification performances, the Energy and Atmosphere (EA) category has a high propelling effect, the Sustainable Sites (SS) and Environmental Quality (EQ) categories have moderate propelling effects, the Water Efficiency (WE), Materials and Resources (MR), and Innovation in Design (ID) categories have low propelling effects. Six of the eight states used an EA-high emphasized strategy, and two of the eight states used a SS/EA/WE/EQ/ID-moderate emphasized strategy. The single-state-year group and state-and-total-years group analyses are more robust than the pooling LEED projects using the total state-and-year group analysis.

The whitefly Bemisia tabaci harbors Portiera aleyrodidarum, an obligatory symbiotic bacterium, as well as several secondary symbionts, including Rickettsia, Hamiltonella, Wolbachia, Arsenophonus, Cardinium and Fritschea, the function of which is unknown. In Israel, Rickettsia is found in both the B and Q ofB. tabaci biotypes, and while all other secondary symbionts are located in the bacteriomes, Rickettsia can occupy most of the body cavity of the insect. We tested whether Rickettsia influences the biology of B. tabaci and found that exposing a Rickettsia-containing population to increasing temperatures significantly increases its tolerance to heat shock that reached 40~C, compared to a Rickettsia-free population. This increase in tolerance to heat shock was not associated with specific induction of heat-shock protein gene expression; however, it was associated with reduction in Rickettsia numbers as was assessed by quantitative real-time polymerase chain reaction and fluorescence in situ hybridization analyses. To assess the causes for thermotolerance when Rickettsia is reduced, we tested whether its presence is associated with the induction of genes required for thermotolerance. We found that under normal 25℃ rearing temperature, genes associated with response to stress such as cytoskeleton genes are induced in the Rickettsia-containing population. Thus, the presence of Rickettsia in B. tabaci under normal conditions induces the expression of genes required for thermotolerance that under high temperatures indirectly lead to this tolerance.

Purpose　To summarize the current strategies for the treatment of early and late Parkinson's disease (PD).Data sources　The presented guidelines are based on the review of the literature as well as the author's extensive experience with the treatment of 7000 patients with PD over the past 25 ***　An analysis of reported data as well as personal experience suggest that while young patients seem to have a slower progression of the disease, they are at a higher risk for developing levodopa induced complications, such as motor fluctuations and dyskinesias. It is, therefore, prudent practice to delay levodopa therapy, particularly in younger patients, until the PD symptoms become troublesome and interfere with social or occupational functioning. Other strategies, such as the use of deprenyl, amantadine, trihexyphenidyl and dopamine agonists, should be employed before instituting levodopa therapy. Entacopone and dopamine agonists are useful in smoothing out levodopa related motor fluctuations. Surgical interventions, such as pallidotomy and pallidal or subthalamic deep brain stimulation, are effective therapeutic strategies, but should be reserved only for patients in whom optimal medical therapy fails to provide satisfactory control of ***　The medical and surgical treatment of patients with PD must be individualized and tailored to the needs of the individual patient.

Microbial enhanced oil recovery （MEOR） methods apply injection of bacteria to depleted oil reservoirs to produce oil, which had remained unrecovered after the conventional methods of production. The ability ofthermophilic anaerobic bacteria to produce gas as the main mechanism in potential MEOR in high salinities of 70-100 g/L was investigated in this study. Maximum gas production of up to 350 mL per 700 mL of salty solution was produced at a salinity of 90 g/L stably during 2-4 days of experiment. The experimental results were upscaled to the Snorre Oilfield, Norway, and simulated using ECLIPSE software for 27 months. The best scenarios showed that the increase in oil recovery on average was at 21% and 17.8% respectively. This study demonstrated that anaerobic bacteria used in biogas plants could be an attractive candidate for MEOR implementation due to their ability to withstand high temperature and salinity, and produce gas in large volumes.
