The paper deals with cylindrical tanks. Structures of this type have been used in hydraulic engineering, e.g. water towers, sewerage plant tanks. In recent years, cylindrical tanks have been also used in biogas management as fermentation and storage tanks.While the standard hydrostatic load acts symmetrically, it evokes the rotary symmetric load. During the seismic event, the load acts in one direction only, i.e. in the direction of earthquake. This load imposes a non-symmetrical loading of a structure. By a combination of individual loads the resulting forces are slightly non-symmetrical.Specific tank has been modeled. In one model, the solution is made using the quasi-static load induced by the hydrodynamic pressure according to the standard EC1998, part 4 [12]. The other model is presented as a calculation using the modal and spectral analyses under the seismic load. At the conclusion, these two solutions have been compared.

Isoelectric focusing on polyacrylamide gel columns of three native crystalline commercial preparations of insulin and 125I-labelled insulin was carried out. All the compounds studied contained three components of different isoelectric points. The largest fraction, having pI 5.60 ± 0.05, was common to all preparations. The other two fractions were situated in the acid region of pH between pI 4.5 and 5.2. The presence of these fractions is explained by the contamination of crystalline insulins by proinsulin and by the formation of des-amido derivatives during the dissolving and storage of insulin samples, and, in case of labelled insulin, also by the presence of heavily iodinated insulin and contaminating components. The isoelectric focusing of the complex 125I-insulin-antibody showed a peak of radioactivity having pI 6.15 ± 0.05.

Tonsils and inguinal, mesenteric, and prescapular lymph node samples collected from 115 swine carcasses from two abattoirs and a family-run operation in the State of Rio de Janeiro, Brazil, were cultured for the presence of Salmonella species. Salmonella spp. were detected in 40 (34.8%) of the swine samples with the following distribution; tonsils (31/40, 77.5%), mesenteric lymph nodes (16/40, 40.0%), inguinal lymph nodes, (9/40, 22.5%), and prescapular lymph nodes (7/40, 17.5%), Scalding tank water and environmental swabs collected from the abattoirs were also analyzed. Salmonella spp. were recovered from 13 of 51 (22.5%) of the environmental samples from one of the two abattoirs, none from those from the other abattoir. Salmonella spp. were recovered from the evisceration tables (5/11, 45.5%), the killing room (3/10, 30.0%), the holding pen (2/10, 20.0%), the butchering saw (2/10, 20.0%), and the scalding tank (1/10, 10.0%). The most frequently detected serovar was Salmonella Muenster. The results show the necessity of adopting more effective hygienic measures in the abattoirs as well as in the areas where swine are raised in order to reduce the role of abattoirs and storage facilities in the spread of Salmonella contamination.

Volatile Esters

Examples from various harvest regimes, storage regimes, cultivars and different packaging methods are presented to characterize volatile ester differences after cutting and how changes occur in characteristic flavors throughout the postharvest life of certain cut fruit products. In many fresh-cut cantaloupe cultivars and in honeydew, there was a relative increase in nonacetates and coinciding relative decrease in acetates during storage. A similar and consistent nonacetate:acetate ester ratio was conserved in cantaloupe from eastern and western U.S. regions, as well as different cultivars from the same field. Furthermore, similar ratios were observed in many melon cultivars over multiple years from different seasons and growing regions. Since many cultivars exhibited similar trends in 2-year repeated studies, the trend is apparently independent of year and season. Fresh-cut `Gala' apples, on the other hand, displayed a slightly different trend whereby both acetates and nonacetate esters decreased appreciably during storage. The hypothesis is put forward that recycling of esters during storage in certain fresh-cut fruits disturbs the delicate fine balance of characteristic volatiles. Consistently decreasing acetates along with increasing nonacetates could alter the overall perceived desirable flavor attributes during fresh-cut melon storage, even though volatile esters are still abundant.

In three-year field experiments, the effect of genotype, flesh color, site conditions and storage on chlorogenic acid content (CAC) in tubers of potato cultivars with purple or red flesh was compared to yellow-fleshed cv. Agria. The results confirmed the significant effect of genotype on CAC. The highest CAC was characteristic on a three-year mean for the purple-fleshed cv. Vitelotte (769.5 mg/kg fresh weight (FW)), i.e. 1.19−2.6 times higher than in the other cultivars. In regard to the effect of flesh color, significantly higher mean CAC levels have been shown for the red-fleshed (2.8 times) and purple-fleshed (3.16 times) cultivars in comparison with cv. Agria (148 mg/kg FW). At the Uhříněves location with a warmer climate and frequent dry periods as compared to the second Valečov location, a higher CAC (1.18 times) was found. Cold storage (4°C, 6 months) resulted in a significant CAC increase varying from 33.2% in the Blaue St. Galler cultivar to 210.6% in the Vitelotte cultivar among all eight evaluated color-fleshed cultivars. On the other hand, the effect of storage on CAC was not evident in the yellow-fleshed Agria cultivar (inconclusive difference against CAC after harvest).

Abstract Background Some therapeutic drugs are unstable during sample storage in gel tubes. BD Vacutainer® Barricor™ Plasma Blood Collection Tube with nongel separator was compared with plasma gel tubes, BD Vacutainer PST™, PST II, and BD Vacutainer Serum Tube for acetaminophen, salicylate, digoxin, carbamazepine, phenytoin, valproic acid, and vancomycin during sample storage for up to 7 days. Methods Seven hospital sites enrolled 705 participants who were taking at least one selected drug. The study tubes were collected and tested at initial time (0 h), after 48 h of storage at room temperature and on day 7 (after additional 5 days of refrigerated storage). The performance of BD Barricor tube was evaluated for each drug by comparing BD Barricor samples with samples from the other tubes at 0 h from the same participant; stability was evaluated by comparing test results from the same tube at 0 h, 48 h, and 7 days. Results At 0 h, BD Barricor showed clinically equivalent results for selected therapeutic drugs compared with the other tubes, except phenytoin in BD PST. Phenytoin samples ≥20 µg/mL in BD PST had 10–12% lower values than samples in BD Barricor. During sample storage, all selected drugs remained stable for 7 days in BD Barricor and in serum aliquots. In BD PST, all drugs remained stable except phenytoin and carbamazepine and in BD PST II except for phenytoin. Conclusion The BD Barricor Tube is effective for the collection and storage of plasma blood samples for therapeutic drug monitoring without sample aliquoting.

Air Permeation

ABSTRACTSarin gas is a dangerous chemical warfare agent (CWA). It is a nerve agent capable of bringing a person to death in about 15 minutes. A lethal concentration of sarin molecules in air is about 30 mg/m3. Experimental research on this gas requires very careful safety protocols for handling and storage. Therefore, theoretical and computational studies on sarin gas are very welcome and might provide important safe guides towards the management of this lethal substance. In this work, we investigated the interactions between sarin, air and nanoporous graphene, using tools of classical molecular dynamics simulations. Aiming to cast some light in the possible sarin selective filtration by graphene, we designed a bipartite simulation box with a porous graphene nanosheet placed at the middle. Sarin and air molecules were initially placed only on one side of the box so as to create an initial pressure towards the passage of both to the other side. The box dimensions were chosen so that the hole in the graphene was the only possible way through which sarin and air molecules can get to the other side of the box. The number of molecules that passed through the hole in graphene was monitored during 10 ns of simulation and the results for different temperatures were compared. The results show that, as far as the size of the holes are small, van der Waals forces between graphene and the molecules play a significant role on keeping sarin near graphene, at room temperature.

The effects of 3 common handling procedures and mishaps (dropping, compression and trimming) applied to Chinese cabbage cv. Yuki [Brassica campestris L. ssp. pekinensis (Lour.) Olsson] were compared to unstressed control cabbages. Heads were mechanically stressed by dropping from 50 cm onto a hard floor, by prolonged compression under 3 kg of weight before storage, or by repeated trimming of the outer leaves during storage. Cabbages were stored at 2°C for 9 weeks. Market quality of cabbages was not affected by the mechanical stresses, but storage for 9 weeks reduced marketable quality. Heads that were repeatedly trimmed produced less ethylene at the end of the storage period compared to the start, and less ethylene than the other treatments (due to the removal of outer senescing and rotting leaves); however, marketable yield was not improved.
