Biofilm growth and control in cooling water industrial systems.

Matrix-embedded, surface-attached microbial communities, known as biofilms, profusely colonise industrial cooling water systems, where the availability of nutrients and organic matter favours rapid microbial proliferation and their adhesion to surfaces in the evaporative fill material, heat exchangers, water reservoir and cooling water sections and pipelines. The extensive growth of biofilms can promote micro-biofouling and microbially induced corrosion (MIC) as well as pose health problems associated with ...

Management of Chemotherapy-Induced Alopecia With Scalp Cooling.

Chemotherapy-induced alopecia is a common and distressing adverse effect of many types of chemotherapy. Scalp cooling has been used since the 1970s for prevention of chemotherapy-induced alopecia; however, most data regarding this treatment modality are retrospective in nature, and use in the United States has been limited by safety concerns, specifically the potential for scalp metastases. Two prospective studies of scalp-cooling systems performed in the United States were published within the last year an...

Evaluating the crystallization of lactose at different cooling rates from milk and whey permeates in terms of crystal yield and purity.

The cooling rate of supersaturated lactose solution is one of the important parameters determining the yield and size distribution of lactose crystals. The influence of increasing cooling rate on lactose crystallization and quality of lactose crystals was evaluated in concentrated solutions prepared from deproteinized whey powder (DPW) and milk permeate powder (MPP). Concentrated permeates (DPW and MPP) with 60% (wt/wt) total solids were prepared by reconstituting permeate powders in water at 80°C for 2 h ...

A radiative forcing analysis of tropical peatlands before and after their conversion to agricultural plantations.

The tropical peat swamp forests of Southeast Asia are being rapidly converted to agricultural plantations of oil palm and Acacia creating a significant global "hot-spot" for CO emissions. However, the effect of this major perturbation has yet to be quantified in terms of global warming potential (GWP) and the Earth's radiative budget. We used a GWP analysis and an impulse-response model of radiative forcing to quantify the climate forcing of this shift from a long-term carbon sink to a net source of greenho...

Physical characteristics cannot be used to predict cooling time using cold-water immersion as a treatment for exertional hyperthermia.

We examined if physical characteristics could be used to predict cooling time during cold water immersion (CWI, 2°C) following exertional hyperthermia (rectal temperature ≥39.5°C) in a physically heterogeneous group of men and women (n=62). Lean body mass was the only significant predictor of cooling time following CWI (R2=0.137; P

Quantifying Polaron Formation and Charge Carrier Cooling in Lead-Iodide Perovskites.

Notwithstanding the success of lead-halide perovskites in emerging solar energy conversion technologies, many of the fundamental photophysical phenomena in this material remain debated. Here, the initial steps following photogeneration of free charge carriers in lead-iodide perovskites are studied, and timescales of charge carrier cooling and polaron formation, as a function of temperature and charge carrier excess energy, are quantified. It is found, using terahertz time-domain spectroscopy (THz-TDS), that...

27.5  W/m collection efficiency solar laser using a diffuse scattering cooling liquid.

We report a solar pumped solid state laser using a 20 mm long, 3 mm diameter neodymium-doped yttrium aluminum garnet laser rod. This rod was placed in a liquid cooling chamber using a water-white-emulsion-paint mix. This mix provides cooling for the laser crystal and also doubles as a diffuse light scattering liquid. This enhances sunlight scattering and leads to a greater absorption in the laser rod. We numerically model the solar absorption in the laser rod using a ray-tracing model and predict a 2.6 ti...

Widespread asymmetric response of soil heterotrophic respiration to warming and cooling.

Soil is the largest organic carbon (C) pool in terrestrial ecosystems. Periodic changes in environmental temperature occur diurnally and seasonally; yet, the response of soil organic matter (SOM) decomposition to varying temperatures remains unclear. In this study, we conducted a modified incubation experiment using soils from 16 forest ecosystems in China with periodically and continuously varying incubation temperature to investigate how heterotrophic respiration (R) responds to different temperature patt...

Does Gender Affect Rectal Temperature Cooling Rates?: A Critically-Appraised Topic.

Clinical Scenario: Exertional heat stroke (EHS) is a medical emergency characterized by body core temperatures >40.5°C and central nervous system dysfunction. An EHS diagnosis should be immediately followed by cold-water immersion (CWI). Ideally, EHS victims cool at a rate >0.15°C/min until temperature reaches 38.9°C. While generally accepted, these EHS treatment recommendations often stem from research which only examined males. Since gender differences exist in anthropomorphics (e.g., body surface area...

Differential contribution of calcium channels to α-adrenoceptor-mediated contraction is responsible for diverse responses to cooling between rat tail and iliac arteries.

Our previous studies have shown that α-adrenoceptors, in addition to α-adrenoceptors, are involved in enhanced contraction of cutaneous blood vessels during cooling. The present study aimed to elucidate the mechanism underlying it. In tail and iliac arteries isolated from rats, isometric contraction was measured using a myograph and the phosphorylation level of myosin phosphatase target subunit 1 (MYPT1) was quantified by western blotting. The phenylephrine-induced contraction was enhanced by cooling to 2...

Budget impact analysis of long-acting injectable aripiprazole once-monthly 400 mg in bipolar I disorder in the USA.

To estimate the budget impact (BI) of introducing aripiprazole once-monthly 400 mg/300 mg (AOM 400) in the maintenance monotherapy treatment of bipolar I disorder versus long-acting injectables, oral antipsychotics and best supportive care.

Optical Cooling of Magnons.

Inelastic scattering of light by spin waves generates an energy flow between the light and magnetization fields, a process that can be enhanced and controlled by concentrating the light in magneto-optical resonators. Here, we model the cooling of a sphere made of a magnetic insulator, such as yttrium iron garnet, using a monochromatic laser source. When the magnon lifetimes are much larger than the optical ones, we can treat the latter as a Markovian bath for magnons. The steady-state magnons are canonicall...

Spectrally Selective Nanocomposite Textile for Outdoor Personal Cooling.

Outdoor heat stress poses a serious public health threat and curtails industrial labor supply and productivity, thus adversely impacting the wellness and economy of the entire society. With climate change, there will be more intense and frequent heat waves that further present a grand challenge for sustainability. However, an efficient and economical method that can provide localized outdoor cooling of the human body without intensive energy input is lacking. Here, a novel spectrally selective nanocomposite...

Budget impact of a program for safely reducing caesarean sections in Canada.

audits of indications for cesarean section (CS), feedback for health professionals, and implementation of best practices, as compared with usual care (QUARISMA study), resulted in a small reduction in the rate of CS in Quebec and important cost savings from a health care payer perspective. Determining the budget impact would enable estimation of the financial consequences if the program is extended nationwide.

Predator-prey equations with constant harvesting and planting.

We propose Lotka-Volterra type predator-prey equations which include small constant terms. Depending on its sign, the constant may model various things. To see the effect of the constants clearly we drop all other functional responses except the ones in the original Lotka-Volterra equations. We add a small negative constant for the harvesting or the Allee effect. A positive constant is added to model the planting or external influx. We find the predator-prey equations with constant terms produce most of dyn...

Effects of solidification cooling rate on the corrosion resistance of a biodegradable β-TCP/Mg-Zn-Ca composite.

This investigation was conducted to study the effect of cooling rate on the microstructure and corrosion behavior of a biodegradable β-TCP/Mg-Zn-Ca composite. The composite was fabricated under a series of cooling rates using a wedge-shaped casting mold. The microstructure of the composite was examined by optical and scannin...

Therapeutic cooling is associated with better function in children with cerebral palsy due to birth asphyxia according to the national health care quality registry CPUP.

Hypothermic treatment after birth asphyxia was introduced as a recommended practice in Sweden in 2007. CPUP is a national quality register and surveillance program that encompasses the total population of children with cerebral palsy (CP) in Sweden. In an analysis of CPUP data children with CP and asphyxia treated with cooling were compared to children with CP and asphyxia who were not cooled. A lower proportion of severe motor and cognitive impairments were observed in the group that did receive the coolin...

Targeted Temperature Management: Peltier's Element-Based Focal Brain Cooling Protects Penumbra Neurons from Progressive Damage in Experimental Cerebral Ischemia.

Targeted temperature management (TTM), or therapeutic hypothermia, is one of the most potent neuroprotective approaches after ischemic and traumatic brain injuries. TTM has been applied clinically with various methods, but effective achievement and maintenance of the target temperature remain challenging. Furthermore, timing of cooling and target body and brain temperature to optimize effectiveness for neuroprotection and to minimize side effects are yet to be standardized. Focal brain cooling is a potentia...

Theoretical analysis of evaporative cooling of classic heat stroke patients.

Heat stroke is a serious health concern globally, which is associated with high mortality. Newer treatments must be designed to improve outcomes. The aim of this study is to evaluate the effect of variations in ambient temperature and wind speed on the rate of cooling in a simulated heat stroke subject using the dynamic model of Wissler. We assume that a 60-year-old 70-kg female suffers classic heat stroke after walking fully exposed to the sun for 4 h while the ambient temperature is 40 °C, relative hum...

α-Adrenoceptors, but not α- or α-adrenoceptors, contribute to enhanced contractile response to phenylephrine in cooling conditions in the rat tail artery.

Cutaneous arteries show enhanced contraction in response to cooling, which is suggested to be mediated via α-adrenoceptors. We have previously shown that α-adrenoceptors are also involved in the enhanced contraction in cooling conditions. In the present study, we aimed to identify the α-adrenoceptor subtype involved in the response. Phenylephrine-induced contraction was enhanced by cooling to 24°C in isolated rat tail arteries but suppressed in iliac arteries and aorta. At 37°C, RS100329 (3nM), an α-a...

Lower Extremity Cooling Reduces Ischemia-Reperfusion Injury Following Zone 3 REBOA in a Porcine Hemorrhage Model.

New strategies to mitigate ischemia during REBOA and to prolong its maximal duration are needed. We hypothesized that simple external cooling of the hind limbs would decrease ischemia-reperfusion injury following prolonged Zone 3 REBOA.
