widget: source_sentence: Abstract Simple and rapid voltammetric method for simultaneous determination of all trans retinyl acetate (RAc) or all trans retinyl palmitate (RPa) and tocopheryl acetate (TOAc) has been proposed. The respective method was based on the anodic oxidation of the compounds of interest by squarewave voltammetry in acetone with mol L LiClO at the glassy carbon electrode. The procedure was also beneficial with respect to simple dissolution of sample directly in the supporting electrolyte. The all trans retinyl acetate could be quantified in two linear ranges ( mol L and mol L ) and tocopheryl acetate in linear range mol L with detection limits of mol L RAc (or mol L RPa) and of mol L TOAc. Selected commercial cosmetic products were analysed achieving satisfactory recoveries.
sentences: The nitrification inhibitors (NIs) -dimethylpyrazole (DMPP) and dicyandiamide (DCD) can effectively reduce N0 O emissions; however, which species are targeted and the effect of these NIs on the microbial nitrifier community is still unclear. Here, we identified the ammonia oxidizing bacteria (AOB) species linked to N0 O emissions and evaluated the effects of urea and urea with DCD and DMPP on the nitrifying community in a day field experiment under sugarcane. Using an amoA AOB amplicon sequencing approach and mining a previous dataset of 00S rRNA sequences, we characterized the most likely N0 O-producing AOB as a Nitrosospira spp. and identified Nitrosospira (AOB), Nitrososphaera (archaeal ammonia oxidizer) and Nitrospira (nitrite-oxidizer) as the most abundant, present nitrifiers. The fertilizer treatments had no effect on the alpha and beta diversities of the AOB communities. Interestingly, we found three clusters of co-varying variables with nitrifier operational taxonomic units (OTUs): the N0 O-producing AOB Nitrosospira with N0 O, NO0- , NH0+ , water-filled pore space (WFPS) and pH; AOA Nitrososphaera with NO0- , NH0+ and pH; and AOA Nitrososphaera and NOB Nitrospira with NH0+ , which suggests different drivers. These results support the co-occurrence of non-N0 O-producing Nitrososphaera and Nitrospira in the unfertilized soils and the promotion of N0 O-producing Nitrosospira under urea fertilization. Further, we suggest that DMPP is a more effective NI than DCD in tropical soil under sugarcane., In order to achieve cost efficiency, customer satisfaction and also to concentrate on core business operations, many manufacturing firms are outsourcing their logistics activities to third party logistics (0PLs) provider. Reverse logistics is one type of logistics in which used products or end-of-life products are collected from the customers/retailers and send for reuse, refurbishing, recycling and/or remanufacturing. The third party reverse logistics provider (0PRLP) who is performing the reverse logistics operations is under a pressure of reducing the transportation cost between the customers and the collecting centre. Decreasing transport costs can be achieved through better utilization of resources such as vehicles (i.e. through proper vehicle routing). This study aims to find the optimal routes which will minimize the total distance traveled and corresponding transportation costs for a 0PRLP who transports the used tires from various customers to the centralized depot for the purpose of tire remanufacturing/retreading. A hybrid approach of combining Sweep and Clarke-Wright savings algorithm with Simulated Annealing (SA) algorithm is proposed in this study and also the results of SA are compared with Sweep and Clarke-Wright savings algorithm results., Abstract Orientin, eriodictyol and robinin are polyphenolic compounds, and their oxidation mechanism is pHdependent, in two steps, involving a different number of electrons and protons. Orientin and eriodictyol first oxidation occurs at a lower potential, corresponding to the reversible oxidation of the catechol group, and is followed by an irreversible oxidation on the ringA at more positive potential. Robenin oxidation is irreversible, with the formation of electroactive products, and occurs at ringA and ringB. The electrochemical characterization of their redox behaviour brought useful data about their chemical stability, antioxidant and prooxidant activity, enabling a comprehensive understanding of their redox mechanism., source_sentence: This work studied the degradation of polyethylene terephthalate by ethanol with and without catalysts. The degradation without catalyst, PET was introduced into an autoclave with ethanol and heated at the temperature of 000o C for , and hours. After heating it was cooled down to room temperature, amd the product was taken to check percentage yield by the Nuclear Magnetic Resonance Spectrometer. In case of using the catalysts, cobalt acetate, zinc acetate and stannous chloride were used. The results showed that the degradation with the catalysts obtained percentage yield of product, diethylene terephthalate (DET), higher than without catalyst for this purpose than zinc acetate and stannous chloride, respectively. The DET yield increased with an increase in the reaction time.
sentences: Poplars and willows planted on farms for soil conservation and shelter are also potential sources of supplementary forage. The objective of this paper is to provide information that assists in the estimation of the value of poplar and willow forage. The quantity of forage in trees and branches was measured and non-destructive methods for estimating forage yield were evaluated. The edible forage dry matter (DM) of - -year-old trees ranged from - kg DM/tree. The edible forage yield of poplar and willow branches with a basal diameter (BD) up to mm was shown to be estimated from kg DM = BD - . The nutritive values of poplars and willows were found to be similar, but the concentration of condensed tannins was usually higher in willows. Tree bark was found to have sufficient nutritive value to be stripped from trees for its feed value by livestock. Cattle were observed to be able to browse willows to a height of 0m and to eat stems with a diameter from to mm. Keywords: browse estimation, condensed tannins, nutritive value, poplar, supplements, willow, In Lake Rogoznica, a small saline and eutrophic lake on the coast of the Adriatic Sea, the copepod Acartia (Acanthacartia) italica Steuer, is common, occasionally as an extremely dense population. This phenomenon provided an opportunity for a redescription of the adults and for description of the developmental stages. The segmentation and setation patterns of the antennules, antennae and mandibles of A. italica are analysed in detail through the naupliar and copepodid phases and the other limbs are analysed through the copepodid phase. In addition, wider comparisons are made with available data for other species of the subgenus Acanthacartia Steuer, ., This research studied the effect of other plastics blending on the degradation of polypropylene by mixing polyethylene and polystyrene as impurities with polypropylene in concentrations of %, %, % and % by weight and pyrolysing under nitrogen atmosphere. From the thermal analysis by Thermo gravimetric analyzer (TGA), it is found that the virgin polypropylene was degraded at oC and that for polyethylene blending on polypropylene, the temperature of degradation was increased to the range of oC and for polrstyrene blending on polypropylene, temperature was decreased to the range of oC. The pyrolysis of plastics mixtures in various ratios at oC gave oil, gas and residue as product. The oil and gas are mixture of micro molecular hydrocarbon and their derivatives which could be served as feedstock for light olifins manufacture in the same way as crude petroleum, source_sentence: Abstract Full-length A0- and A0- , N-truncated pyroglutamate A0- and A0- are major variants in the Alzheimer brain. A0- has not been considered as a therapeutic target yet. We demonstrate that the antibody NT0X and its Fab fragment reacting with both the free N-terminus of A0-x and pyroglutamate A0-X mitigated neuron loss in Tg0- mice expressing A0- and completely rescued spatial reference memory deficits after passive immunization. NT0X and its Fab fragment also rescued working memory deficits in wild type mice induced by intraventricular injection of A0- . NT0X reduced pyroglutamate A0-x, Ax- and Thioflavin-S positive plaque load after passive immunization of 0XFAD mice. A0-x and Ax- plaque deposits were unchanged. Importantly, for the first time, we demonstrate that passive immunization using the antibody NT0X is therapeutically beneficial in Alzheimer mouse models showing that N-truncated A starting with position four in addition to pyroglutamate A0-x is a relevant target to fight Alzheimer's disease.
sentences: Abstract Maternal hypoglycaemia throughout gestation until gestation day (GD) delays foetal growth and skeletal development. While partially prevented by return to normoglycaemia after completed organogenesis (GD00), underlying mechanisms are not fully understood. Here, we investigated the pathogenesis of these changes and significance of maternal hypoglycaemia extending beyond organogenesis in non-diabetic rats. Pregnant rats received insulin-infusion until GD00 or GD00, with sacrifice on GD00. Hypoglycaemia throughout gestation increased maternal corticosterone levels, which correlated with foetal levels. Growth plates displayed central histopathologic changes comprising disrupted cellular organisation, hypertrophic chondrocytes, and decreased cellular density; expression of pro-angiogenic factors, HIF- and VEGF-A increased in surrounding areas. Disproportionately decreased growth plate zone volumes and lower expression of the structural protein MATN- were seen, while bone ossification parameters were normal. Ending maternal/foetal hypoglycaemia on GD00 reduced incidence and severity of histopathologic changes and with normal growth plate volume. Compromised foetal skeletal development following maternal hypoglycaemia throughout gestation is hypothesised to result from corticosterone-induced hypoxia in growth plates, where hypoxia disrupts chondrocyte maturation and growth plate structure and volume, decreasing long bone growth. Maternal/foetal hypoglycaemia lasting only until GD00 attenuated these changes, suggesting a pivotal role of glucose in growth plate development., The observation of significant neutron yield from gas loaded titanium samples at Frascati in April opened up an alternate pathway to the investigation of anomalous nuclear phenomena in deuterium/solid systems, complimenting the electrolytic approach. Since then at least six different groups have successfully measured burst neutron emission from deuterated titanium shavings following the Frascati methodology, the special feature of which was the use of liquid nitrogen to create repeated thermal cycles resulting in the production of nonequilibrium conditions in the deuterated samples. At Trombay several variations of the gas loading procedure have been investigated including induction heating of single machined titanium targets in a glass chamber as well as use of a plasma focus device for deuteriding its central titanium electrode. Stemming from earlier observations both at BARC and elsewhere that tritium yield is times higher than neutron output in cold fusion experiments, we have channelised our efforts to the search for tritium rather than neutrons. The presence of tritium in a variety gas/plasma loaded titanium samples has been established successfully through a direct measurement of the radiations emitted as a result of tritium decay, in contradistinction to other groups who have looked for tritium in the extracted gases. In some samples we have thus observed tritium levels of over MBq with a corresponding (t/d) ratio of ., Two small areas of middle Paleozoic limestone were discovered near Gertrude Creek, km north of Becharof Lake on the Alaska Peninsula, during reconnaissance flying as part of the Alaska Mineral Resource Assessment Program (AMRAP) for the Alaska Peninsula. Previously, the only known occurrence of Paleozoic rocks on the Alaska Peninsula was a small exposure of middle Permian limestone on an island at the entrance to Puale Bay (Hanson, ). This is the first reported occurrence of middle Paleozoic rocks in what is considered to be a Mesozoic and Tertiary province., source_sentence: Nature Reserve now has become one of the foci of tourism.There are a number of arguments and treaties on tourism exploitation in this special area.Unfortunately,in the process of dealing with the conflicts between reservation and exploition,we emphasizes the latter,and neglects its prerequisite-reservation;as a result,inappropriate tourism development has destroyed the local ecosystem to some extent.This article makes an inquiry into the advantages and factual condition of tourism development in Nature Reserve,analyses emphatically the ecological risks caused by blind tourism exploitation,points out that the Nature Reserve should be exploited appropriately under protecting conditions and finally puts forward the countermeasures against the problem.
sentences: This study involved studying fatigue crack propagation in elastic-plastic and linear elastic fracture mechanics LEFM fracture mechanics EPFM for each bovine and cadaveric human cortical bone. The results of the fatigue crack propagation showed that the fatigue crack propagation in elastic-plastic fracture mechanics is better than fatigue crack propagation in linear elastic fracture mechanics for comparison of the bone at small frequencies. Therefore, fatigue crack growth rate in cadaveric human bone is larger than bovine cortical bone. In addition, the cutting of the bone by hand saw is the better method than any an electric cutting machine., Bacteriolyses of bacterial cell walls by zinc () ions on the basis of the results of halo antibacterial susceptibility tests were investigated for the nitrate and the sulfate solutions.From the results obtained by halo antibacterial tests of sulfate solutions against Staphylococcus epidermidis, the antibacterial order is Zn + >Cu + >Ag + >Al + , in which Zn + ions indicate the highest antibacterial effect.Bacteriolysis of S.aureus PGN cell wall by zinc ion is due to the inhibition of PGN elongation by the activation of PGN autolysins of amidases and side-chain endopeptidase.On the other hand, bacteriolysis of E.coli cell wall by zinc ions is attributed to the destruction of outer membrane structure due to degradative enzymes of lipoproteins at N-and C-terminals, and also is dependent on the activities of PGN hydrolases and autolysins of amidases and carboxypeptidase-transpeptidase.Zinc ions induced ROS such as O0 -, H0O0, OH, OH -producing in bacterial cell wall occur oxidative stress., There are some different tendencies in Hu Feng and he Qifang's new-poetry-creation (One is about the struggling at the bottom of society. The other is about the reciting poetry with a cadence in the ivory tower. ) After engaged in the theoreti-cal research, Hu has independent and individual theoretical character and he still combines his theory with his creative experience from beginning to end. However, He catches obvious dogmatism and often neglects the creative experience. While some inde-pendent thoughts of latter is inwardly interlinked with the criticized former. But each of them believes himself right. There is pro-found and deep cultural connotation under social environment., source_sentence: The aim of the study is to describe our experience with ultrasound guided drainage of tubo-ovarian abscess with concomitant use of antibiotics in a second level center. Seven women diagnosed with a tubo-ovarian abscess and treated with transvaginal ultrasound guided drainage with concomitant use of antibiotics, between January and January , were reviewed. Intravenous antibiotics were administered as soon as the diagnosis was reached and transvaginal ultrasound guided aspiration of the abscess material was performed within hours with no need of anaesthesia. Transvaginal route was used since it provides a better visualization and access to the region of interest than other ultrasound routes. All cases but one ( %) improved clinically within hours of aspiration and only one required surgery due to refilling of a bilateral tubo-ovarian abscess hours after drainage. Mean hospital stay was days (range - ). No procedure related complications were diagnosed. A follow up ultrasound six months after the drainage showed in cases sonographic markers of chronic tubal inflammatory disease but in all cases the patients remained asymptomatic. Transvaginal ultrasound-guided drainage with concomitant antibiotics appears to be a safe, efficacious and well tolerated procedure in the treatment approach of tubo-ovarian abscess as reported in the literature. We consider this approach as a feasible alternative to surgical drainage whenever indicated.
sentences: To compare the usefulness and accuracy of sonographically guided endometrial biopsies. After obtaining informed consents endometrial biopsies were performed using ultrasound guidance in patients followed by operative hysteroscopy. Diagnostic accuracy and treatment efficiency for sono guidance were established. The hysteroscopic procedure was in all cases started by using a fore-oblique mm hysteroscope (Karl Storz®️ Endoscopy-America, Inc. Corporate Pointe, Culver City, CA - ) with a diagnostic sleeve through the cervical os (Karl Storz®️ Endoscopy-America, Inc. Corporate Pointe, Culver City, CA - ), without prior dilatation of the cervix. The catheter used for the polypectomy was an "Intrauterine Access Balloon Catheter" (Cook OB/GYN®️ West Morgan Street, P.O. Box , Spencer, Indiana ). Successful sonographic management of the endometrial pathology had been achieved in patients ( %). Endometrial polyps had been completely removed under sonographic guidance in patients, partially in as confirmed by hysteroscopy. All incompletely removed polyps were of large size (> cm), the remnants were taken out hysteroscopically. Targeted endometrial biopsy was performed under sono guidance in patients. The completion of the procedure was confirmed by hysteroscopy. Targeted endometrial biopsies and polyp removal can be successfully performed under sonographic guidance. Large size endometrial polyps may require hysteroscopy., Aqueous colloidal suspensions of clay platelets display a sol/gel transition that is not yet understood. Depending on the nature of the clay, liquid-crystalline behavior may also be observed. For example, the suspensions of beidellite display a nematic phase whereas those of montmorillonite do not. Both beidellite and montmorillonite have a "TOT" structure but the structural electric charge is located in the tetrahedral layer for the former and in the octahedral layer for the latter. We built a setup to perform SAXS experiments on complex fluids submitted to an electric field in situ. We found that the fluid nematic phase of beidellite suspensions readily aligns in the field. However, the field had no influence on the gels, showing that the orientational degrees of freedom of the platelets are effectively frozen. Moreover, strong platelet alignment was induced by the field in the isotropic phase of both clays, in a similar way, regardless of their ability to form a nematic phase. This surprising result would suggest that the orientational degrees of freedom are not directly involved in the sol/gel transition. The ability to induce orientational order in the isotropic phase of clay suspensions can be exploited to prepare materials of controlled anisotropy., The article is devoted to the peculiarities of the paid domestic labor market in the Russian economy. It is shown that this market is characterized by the following features: weak state regulation; a high proportion of internal and external migrants; a wide spread of the shadow economy and informal labor relations; gender differences; the presence in the market of an "elite" segment of workers providing higher-quality and highly paid services, and a segment of workers performing temporary, episodic work. It is proved on the basis of market analysis that there is a predominant demand for skilled labor, and wages are at or above the national average. It is concluded that further efforts are needed to legalize the work of domestic workers within the framework of the state employment policy.
