Herbal teas have been used as medicinal aids for centuries to treat a myriad of illnesses and have also been suggested to function in chemoprevention. Having numerous phytochemicals, the purported health benefits of herbal teas may be due to their antioxidant potential. Herbal tea blends infused with spices are increasing in popularity in U.s., and preliminary studies suggest the synergistic effects of combining herbal teas and spices. some teas that are increasing in popularity include raspberry leaf, strawberry leaf, and hibiscus. The objectives of this study were to determine the antioxidant capacity of tea beverages (herbal (HT) (functional yogurt-based beverage-new product) and Chai (CT) (store bought) and to determine consumer preferences of tea beverages (HT and CT). Total phenolic content (TPC), total flavonoid content (TFC), free radical scavenging activity by 1,1-diphenyl-2-picryhydrazyl (DPPH), trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP) were evaluated in methanolic and aqueous beverage extracts. A functional yogurt-based beverage (HT) was developed and sensory analysis was also conducted using a 5-point hedonic scale comparing consumer preference of HT or CT beverages. The highest phenolic content was observed in CT aqueous extracts (AQ) (500 mg GAE/g), all other extracts had significantly (P ≤ 0.05) lower phenolic content. CTAQ had significantly (P ≤ 0.05) higher flavonoid content compared to all other extracts (1.7 mg CAE/g). The highest DPPH radical scavenging activity was observed in HT methanolic extracts (ME) (44.48% inhibition). The lowest DPPH radical scavenging was observed in HTAQ (21.88% inhibition). Approximately 61% of sensory panelists gave the yogurt-based developed product a rank of 4 or greater (on a 5-point hedonic scale) with 41% of panelists preferring the HT beverage over CT beverage. The results of this study suggest that a combination of herbal teas and spices may benefit consumers by

The main aim of investigating activity concentrations together with distribution of radionuclides naturally in soil from Kargi was to evaluate radiological health hazard together with environmental radioactivity. Research shows radionuclides as one source of exposure due to radiation with detrimental effects health wise for populations found in areas considered high background radiation. After collecting 117 soil samples from the area, analysis was done in order to measure their natural radioactivities due to sup>40sup>K, sup>232sup>Th and sup>226sup>Ra radionuclides. Measurements method of gamma spectrometry employing a high purity germanium (HPGe) detector was employed basically to evaluate the radiological hazard of radioactivities. For sup>40sup>K, sup>232sup>Th and sup>226sup>Ra, mean calculated activities were 353.19 ± 110.07, 7.98 ± 3.98 and 7.37 ± 2.60 Bq·kg sup>-1sup> respectively. Mean values of absorbed and effective dose rates, external and internal hazard indices together with radium equivalent activity were 23.82 ± 6.59 nGy·h sup>-1sup> and 0.14 ± 0.04 msv·y sup>-1sup>, 0.12 ± 0.03 and 0.14 ± 0.04 and 45.90 ± 12.65 Bq·kg sup>-1sup> respectively. Comparing with approved global values, the values were found to be below the given global limits. Evidence of involvement of metasomatic activity of the radioelements or fractionation during weathering is seen as calculations give a higher value Th/U. Excess cancer risk, calculated from the samples showed lower values as compared to global standard values hence minimal chance of getting cancer disease. The area is safe from cancer causing radionuclides.

Copper sulfate and other chelated or complex copper forms are commonly used to manage nuisance and noxious algae and invasive weeds through direct application to aquatic systems. Regulatory scrutiny and perceived non-target species impacts supported the need for an accurate risk assessment of fate and effects of copper applied as a pesticide. Copper inputs to aquatic systems originate from numerous sources (e.g. natural, storm water, industrial) whereas direct pesticide applications account for approximately 13%. Following a pesticide application, copper rapidly partitions to suspended algae and particulates and the majority (>90%) of applied copper is transferred to sediments within 2 days. Copper subsequently shifts to less bioavailable forms and risks to non-target species are significantly decreased. Additionally, the copper that partitions to sediments is diluted through migration to greater sediments depths and accretion. Even when elevated sediment copper concentrations were measured following chronic applications or high treatment levels, no adverse effects to non-target species were observed with laboratory or field experiments. When used appropriately copper can be an effective tool for water resource managers with negligible environmental impact.

A new two-phase cryogenic neutrino detector using electron bubble (e-bubble) specifically in liquid helium is proposed and being developed for real time, high rate measurements of low-energy p-p reac- tion neutrinos from the sun. The e-bubble detector is a time projection chamber-like (TPC) tracking detector. The task of such a neutrino detector is to detect the ionization of the elastically scattered target electrons by incident neutrinos, and then to characterize their energy and direction and to dis- tinguish them from radioactive backgrounds. The ionization signals are expected to be small and hence undergo avalanche amplification in the saturated vapor above the liquid phase by gas electron multi- pliers (GEMs) at high gain. Higher granularity and intrinsically suppressed ion feedback give a good spatial resolution and are the major advantages of this technology. It should be possible to construct such a detector to track charged particles down to 100―200 keV in a massive liquid helium target with fractional millimeter spatial resolution in three-dimensional space, using the GEM-based TPC with a high-resolution CCD camera, for both the electronic and light readout.
