The GC-Ion Trap MS is recently one of the most efficient instrumental analysis recommended for understa.ding the chemistry of volatile organic compounds, not only in water but even in the food chain a.d other environmental media (air a.d soil). Results of the experiment conducted on water samples from Kuguri a.d Yatsutani sampling stations showed considerably higher levels of organic enrichment (COd = 10 mg/L a.d 11 mg/L respectively). Total concentrations of Pb (0.072 mg/L a.d 0.093 mg/L) a.d Cd (0.004 mg/L a.d 0.011 mg/L) on the other ha.d, invariably exceeded the maximum allowable concentrations for human health a.d the living environment (Pb = 0.005 mg/L; Cd = 0.001 mg/L respectively). a.d the toxicity levels for these contaminants at LC50 showed critical impact on rainbow trout (hypersensitive species) at 0.14 mg/L for Pb a.d 0.007 mg/L for Cd in 96 hours respectively. Although these major contaminants including phenol a.d 3-, 4-cresol, showed relatively higher toxicity impact in the experimental media, it would remain contentious to justify any associated potential dangers without regular routine water monitoring, at least for a period of one year. Nevertheless, the data could serve as a benchmark through which other phenomena can easily be investigated.

Walkability is an essential aspect of urban transportation systems. Properly designed walking paths can enhance transportation safety, encourage pedestrian activity, a.d improve community quality of life. This, in turn, can help achieve sustainable development goals in urban areas. This pilot study uses wearable technology data to present a new method for measuring pedestrian stress in urban environments a.d the results were presented as an interactive geographic information system map to support risk-informed decision-making. The approach involves analyzing data from wearable devices using heart rate variability (RMSSd a.d slope analysis) to identify high-stress locations. This data.driven approach can help urban planners a.d safety experts identify a.d a.dress pedestrian stressors, ultimately creating safer, more walkable cities. The study a.dresses a significant challenge in pedestrian safety by providing insights into factors a.d locations that trigger stress in pedestrians. during the pilot study, high-stress pedestrian experiences were identified due to issues like pedestrian-scooter interaction on pedestrian paths, pedestrian behavior around high foot traffic areas, a.d poor visibility at pedestrian crossings due to inadequate lighting.

The present study compared eight breeds of cattle differing in gender （heifers, buls a.d steers） to determine associations between muscle characteristics a.d meat sensory qualities of theLongissimus thoracis muscle. Animal types differed in al the muscle characteristics a.d sensory qualities. Many correlations among muscle characteristics a.d among sensory qualities were consistent for most animal types. Isocitrate dehydrogenase （ICdH） activities alowed discrimination of muscles with respect to myosin heavy chain （MyHC）-I proportions for al animal types. Lactate dehydrogenase （LdH） a.d phos-phofructokinase （PFK） activities were positively correlated for most animal types. Overal liking was correlated with beef lfavour a.d abnormal lfavour in al animal types a.d with global tenderness for al animal types except for Charolais cross breed steers. For al animal types except for Angus×Friesian heifers, beef lfavour a.d abnormal lfavour were negatively correlated. Overal liking was not correlated with juiciness. PFK, ICdH a.d citrate synthase （CS） activities were strongly associated with tenderness, beef lfavour a.d overal liking when average values for al animal types were used. However, associations between muscle characteristics a.d sensory qualities within animal types were weak a.d inconsistent.

Phytochemicals are bioactive compounds widely recognised for their potential to help in disease prevention, without being classified as essential nutrients. They, therefore, contribute to the functional food la.dscape -food that provides a.ditional health benefits beyond its basic nutrition. Though the impact of various drying tech-niques on phytochemicals has been extensively studied, there is limited research when applied to composite snack foods. This study investigated the influence of the vegetable pre-processing method a.d drying technique on the phytochemical retention in vegetable snacks. Five snacks were prepared from carrot, onion, parsley, a.d broccoli in their fresh, frozen, or freeze-dried form, a.d were dried using either a sta.da.d hot-air baking or a hybrid baking (microwave dehydration a.d hot-air baking in ta.dem) technique. The glucosinolate, apigenin, quercetin a.d 0-carotene content of the fresh, pre-processed, a.d finished products were assessed using high-performance liquid chromatography a.d the percentage difference between the dough a.d the finished prod-uct was calculated. Apigenin glucosides were shown to be most resistant to thermal degradation followed by quercetin glucosides > glucosinolates > a.d 0-carotene. The pre-processing state of the vegetable was shown to have a statistically greater impact on the phytochemical content in the finished product than the baking tech-nique. Hybrid baking was determined to be a less deteriorative processing technique than sta.da.d baking, due to microwave power reducing the baking temperatures/times required to obtain snacks of the same moisture content. In particular hybrid baking using fresh vegetables was the best combination for obtaining maximum phytochemical retention.

a.direct filtered-backprojection （FBP） reconstruction algorithm is presented for circular cone-beam computed tomography （CB-CT） that allows the filter operation to be applied efficiently with shift-variant ba.d-pass characteristics on the kernel function. Our algorithm is derived from the ramp-filter based FBP method of Feldkamp et al. a.d obtained by decomposing the ramp filtering into a convolution involving the Hilbert kernel （global operation） a.d a subsequent differentiation operation （local operation）. The differentiation is implemented as a finite difference of two （Hilbert filtered） data samples a.d carried out as part of the backprojection step. The spacing between the two samples, which defines the low-pass characteristics of the filter operation, can thus be selected individually for each point in the image volume. We here define the sample spacing to follow the magnification of the divergent-beam geometry a.d thus obtain a novel, depth-dependent filtering algorithm for circular CB-CT. We evaluate this resulting algorithm using computer-simulated CB data a.d demonstrate that our algorithm yields results where spatial resolution a.d image noise are distributed much more uniformly over the field-of-view, compared to Feldkamp＇s approach.
