Buildings are essential in satisfying our daily need for comfort (privacy, protection from weather, etc.) and are responsible for almost half of the world's total energy consumption. Research at the interface of room comfort and energy efficiency is of critical societal importance.

Genetic testing is recommended as part of an autism assessment, and most parents support genetic testing for their minor children. However, the impact on parents of receiving a monogenetic/ copy number variant diagnosis for autism in their child is not well understood. To explore this, we surveyed and interviewed parents of children in the SPARK study, a study of autism that includes genetic testing.

The first line treatment of TB involves the concurrent use of four drugs: rifampin, isoniazid, pyrazinamide, and ethambutol (RIPE). Given the rising threat of multidrug resistant TB, it is crucial to understand how TB can be treated when first line treatment is not an option.

Recent research suggests that crime may be a psychosocial stressor that contributes to sleep disparities but that finding has been based on subjective measures of crime. We conducted the P18 Neighborhood Study of 250 SMM in New York City, including 211 with adequate GPS tracking data.

A Centers for Medicare & Medicaid Services (CMS) initiative enables participating NFs to bill Medicare for providing on-site acute care to long-stay residents diagnosed with one of six ambulatory care sensitive conditions (pneumonia, congestive heart failure, chronic obstructive pulmonary disease, dehydration, skin infection, and urinary tract infection) that account for many avoidable hospitalizations. This study describes the frequency of initiative-related treatment for the six conditions, both on site and in the hospital, and the health status of residents who were treated.

Arterial punctures for arterial blood gases (ABGs) analysis are described as the most painful laboratory procedure and are performed without the benefit of pain management. This study originated from one nurse's concern about the level of pain her hospitalized patients endured when she drew their ABGs. A review of the literature found that ABG pain relief has not been studied in hospitalized patients.

Here, we directly visualize the conformational dynamics of individual semiflexible polymers in a semidilute solution above the overlap concentration under shear. We observe that the tumbling dynamics are significantly slowed down, in marked contrast to the case of a dilute solution, due to steric interactions with neighboring filaments.

We therefore have developed a simple cleanup procedure for freshwater samples with low nitrate and high DOM concentrations.
Methods: Nitrate and DOM are extracted from a freeze-dried water sample by using a concentrated sodium hydroxide solution.

The nitrogen (δ(15)N) and oxygen isotope (δ(18)O) analysis of nitrate (NO(3)(-)) from aqueous samples can be used to determine nitrate sources and to study N transformation processes. For these purposes, several methods have been developed; however, none of them allows an accurate, fast and inexpensive analysis. Here, we present a new simple method for the isolation of nitrate, which is based on the different solubilities of inorganic salts in an acetone/hexane/water mixture.
