Abstract:

Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total organic C, total N, initial content of easily available N inorganic forms, mineralized N content obtained by aerobic and anaerobic incubations and A-value. The experiment was performed on a test plant and through the application of urea enriched with 5.4% 15N.<br />The studied forest soils are characterized by high mineralization intensity and high N availability indices. Aerobic incubation appears to be the most appropriate method for evaluating the available N content. The amounts of mineralized and nitrified N, obtained by aerobic incubation, with subtraction of the initial content of available mineral N forms are in correlation (P ≤ 0.05) with total organic C content (r = 0.916) and total soil N (r = 0.903) while the correlation with the C/N ratio is poor (r = 0.645).

Abstract:

Abstract Two experiments were conducted to determine the effects of pelletized recycled paper mulch on container plant nutrition. In experiment 1 with Petunia floribunda Hort. ‘Midnight Madness’, 9 g (0.32 oz) of Osmocote 14N-6.2P-11.6K (14-14-14) was applied over or under 2.5 cm (1 in) of recycled paper pellet mulch, or to plants with no paper mulch (control). Leachate samples were collected after microirrigation. Both treatments with paper mulch reduced nitrate (NO3-N) and ammonium (NH4-N) levels in container leachate, compared to the control 21 days after planting (DAP). Shoot dry weight was reduced 53% and 70% for plants fertilized under and over the mulch, respectively, compared to the non-mulched control. At the end of the experiment 40–48% of the total N applied over or under mulch was retained by the recycled paper mulch. In experiment 2 with Petunia grandiflora Hort. ‘Ultra Blue’, mulch and three methods of fertilizer application (over mulch, under mulch, and incorporated in the substrate) were compared. Leachate NO3-N levels were reduced 72% or 68% with fertilizer placed over or under the mulch, respectively, when compared to a non-mulched topdressed treatment 21 DAP. When fertilizer was incorporated into the substrate, paper mulch reduced NO3-N leachate levels 87% compared to the non-mulched treatment. There were no significant differences in leachate NH4-N levels with fertilizer placed over or under the mulch when compared to a non-mulched control 21 DAP. When fertilizer was incorporated into the substrate, paper mulch reduced leachate NH4-N levels 82% compared to the non-mulched control. Shoot dry weight was 84 or 49% lower with fertilizer placed over or under the mulch, respectively, when compared to the topdressed, non-mulched treatment. However, plants grown with fertilizer applied under the mulch were 213% larger than plants with fertilizer applied over the mulch. When fertilizer was incorporated into the substrate, paper mulch reduced shoot dry weight 41% when compared to non-mulched plants. There were no differences between shoot dry weights of plants grown in non-mulched treatments with topdress fertilization or fertilizer incorporated.

Abstract:

Objectives YouTube is the second most visited website in the world and can be a useful resource for patients to gain insight into surgical procedures. A multitude of studies have evaluated the quality of otolaryngology-specific healthcare information available on the YouTube platform, but to our knowledge, the online content regarding functional endoscopic sinus surgery available on this site has not been systematically evaluated. Study Design Cross sectional study. Setting Online. Methods YouTube was searched using the keywords “sinus surgery.” Variables including video length, total number of views, authorship (academic, private practice physician, patient, or third party), objective (advertisement, informative, or patient perspective), inclusion of intra-operative footage, and discussion of balloon sinuplasty were recorded and analyzed by a single reviewer. Results Two-hundred twenty-two videos met inclusion criteria, with a median length of 4 minutes, and a median of 3349 views. The majority of videos were informative (n = 145, 65%), narrated (n = 151, 68%), and did not mention balloon sinuplasty (n = 189, 85%) nor contain intra-operative footage (n = 116, 52%). Private practice physicians were the most common authors (n = 113, 51%), followed by patients (n = 70, 32%), third parties (n = 28, 13%) and academics (n = 11, 5%). Conclusions Sinus surgery is one of the most common ambulatory procedures performed. Online resources such as YouTube can be useful for improving health literacy and patient comfort with medical topics such as functional endoscopic sinus surgery, but it is important for clinicians and patients to understand that there is a spectrum in the authorship, content, and quality of sinus surgery related videos posted online.

Abstract:

Background. Transfascial suture passers (TSPs) are a commonly used surgical tool available in a wide array of tip configurations. We assessed the insertion force of various TSPs in an ex vivo porcine model. Methods. Uniform sections of porcine abdominal wall were secured to a 3D-printed platform. Nine TSPs were passed through the abdominal wall both without and with prolene suture under the following scenarios: abdominal wall only and abdominal wall plus underlay ePTFE or composite ePTFE/polypropylene mesh. Insertion forces were recorded in Newton (N). Results. When passed without suture through the abdominal wall, smaller diameter TSPs required less insertional force (1.50 ± 0.17 N vs 9.68 ± 1.50 N [ P = 0.00072]). Through composite mesh, the solid tipped TSPs required less force than hollow tipped ones (3.87 ± 0.25 N vs 7.88 ± 0.20 N [ P = 0.00026]). Overall, smaller diameter TSPs required less force than the larger TSPs when passed through ePTFE empty (Gore 2.95 ± 0.83 N vs Carter-Thomason 16.07 ± 2.10 N [ P = .0005]) or with suture (Gore 8.37 ± 2.59 N vs Carter-Thomason 19.12 ± 1.10 N [ P = .003]). Conclusions. Diameter plays the greatest role in the force required for TSP penetration. However, when passed through underlay mesh or while holding suture, distal tip shape, the mechanism of suture holding, and shaft diameter all contribute to the forces necessary for penetration. These factors should be considered when choosing a TSP for intraoperative use.

Abstract:

To assess the effects of long-term fertilization on soil available micronutrients in farmland, this study examined diethylenetriaminepentaacetic acid (DTPA) extractable iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) in surface soil with monoculture of corn (Zea mays L.) with a 30-year filed fertilization experiment established in Northeast China. Treatments included no fertilization (CK); nitrogen only (N); nitrogen and phosphorus only (NP); NP and potassium (NPK); NPK plus cornstalk (SNPK), and NPK plus farmyard manure (MNPK). Results showed that DTPA-Fe and Mn were significantly increased with chemical N application, and DTPA-Cu and Zn were significantly increased with farmyard manure amendment, while micronutrients were not significantly different between treatment SNPK and CK. DTPA-Fe and Mn were about twice to threefold in treatments N, NP, and NPK as much as in treatments SNPK, MNPK and CK. DTPA-Cu and Zn in treatment MNPK were about 3.9 and 6.5 times as much as in CK. DTPA-Fe and Mn decreased with the increasing of soil pH and cation exchange capacity, while DTPA-Cu and Zn increased with the increase of soil organic carbon and electrical conductivity.

Abstract:

Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various natural meadow stands by analyzing the following soil characteristics: total organic C, total N, initial content of easily available N inorganic forms, mineralized N content obtained by aerobic and anaerobic incubations and A-value. The experiment was performed on a test plant and through the application of urea enriched with 5.4 % 15N. The investigated soils under natural meadows are characterized with comparatively high mineralization intensity and high N availability indices. Contents of mineral N produced by aerobic incubation and the intensity of the mineralization correlate with the total organic C in the soil and the total N in the soil. Correlation of the availability index of the soil N produced by aerobic incubation with the total organic C and the total N in the soil under natural meadows is almost linear (r = 0.9981 and r = 0.9997, respectively). Contents of mineral N produced by anaerobic incubation, as well as the corresponding N availability and mineralization intensity indices correlate poorly with the mentioned parameters. Efficiency of nitrogen utilization from the applied N-fertilizer by the test crop varies within a wide range of values and correlates with the biomass yields of the test crop.

Abstract:

The reproduction, development and growth of Akodon lindberghi were studied in captivity. The colony was derived from animals captured in Simão Pereira, Minas Gerais state, which represents a new area of geographical distribution known for this species. Twelve males and twelve females were crossed, producing 144 young in 53 litters. Post-partum oestrus was observed and gestation length was estimated in 23 days. Litter size ranged from 1 to 4 with a mean of 2.72 (SD = 0.97, n = 53) and modal size of 3. Sexual dimorphism was neither present in body mass at birth nor at weaning. There was a significant negative correlation between litter size and mass at birth or weaning. Permanent emergence of adult external appearance occurred at 15 days. Puberty for males and females was 43 and 42 days, respectively, and the first fecundation event for two females was recorded at 47 and 54 days of age. The weight growth was described by fitting a Gompertz model. No significant difference was found in any parameter of growth curves for males and females. Measurements (head-body, tail, hind foot and internal and external ear lengths) obtained for adult individuals also did not reveal the presence of sexual dimorphism.

Abstract:

Many drug tests are carried out by means of hair analysis. The aim of the present study was to clarify if and to what extent it is possible to manipulate the results of hair analyses on tetrahydrocannabinol (THC) by using various commercially available everyday products and products advertised on the internet to be able to reduce the concentrations of drugs in hair. Fifty-four THC-positive hair samples were analyzed using liquid chromatography tandem mass spectrometry; they were analyzed untreated or treated with Vodka Gorbatschow® (n = 19), Seborin® hair tonic (n = 11), Zydot® shampoo (n = 6), Desderman® disinfectant (n = 11) and Head and Shoulders® shampoo (n = 7). A mean reduction of 52% (Zydot® shampoo) to 65% (Desderman®) was shown. Hair treatments could not be detected visually. Hair concentrations could also be decreased to non-detectability by using these everyday hair care products. Therefore, it is recommended to complement abstinence controls using hair samples by urine analysis and to not over-interpret quantitative results of THC concentrations in hair.

Abstract:

Among fertilizers, nitrogen (N) is the one that is used in the largest amounts mainly due to immediate response to the fertilizer-N application. However, the N use efficiency (NUE) is very low leading to high production costs and also a threat to the environment. Therefore, improving NUE is imperative. The 4 R’s (right quantity, right time, right method and right source) should be considered as the first step for enhancing NUE. Best management practices (BMP’s) of production and protection need to be adopted in order to achieve high NUE. Integration of novel N sources and nanofertilizers and better N fertilization products would lead to high NUE. Furthermore, novel techniques such as Precision Nutrient Management and Variable Rate Application to time nutrient application with crop need, and remote sensing are upcoming technologies that will bring about considerable savings in fertilizer-N. Further we should also account for plant physiological processes, including the diversity of mineral nutrient uptake mechanisms, their translocation and metabolism in order to breed and develop crop cultivars that are efficient N users.

Abstract:

In the present investigation, an experimental dental arch model fabricated in epoxy was assayed in Kratos universal testing machine to study the mechanical behavior of ethylene and vinyl acetate copolymer (EVA) in the form of mouthguard for sports and flat plate. The following variables were considered: thickness (3 and 4-mm plates), temperature (room and mouth temperature) and presence/absence of artificial saliva. Mechanical properties of EVA were tested under compressive strength: apparent absorbed energy (J.mm-1), maximum tension (N.mm-1), maximum dislocation (mm) and maximum strength (N). Data were recorded and modeled mathematically. Regarding the absorbed energy, maximum tension and maximum force, it was verified that the higher the thickness of the mouthguards, the better the results of force dissipation and redirection to the system and to several regions of the dental arch. In the presence of saliva and close to mouth temperature, the material responded positively to these alterations, resenting increased ductibility as well as improved mechanical responses. Regarding maximum dislocation, it was observed a better accommodation of the occlusion under conditions that simulate those observed in the oral environment. In conclusion, EVA proved to be an adequate material for fabrication of mouthguards and interocclusal splints. In addition, EVA showed good results in force dissipation and demonstrated a shock-absorbing capacity and a great protection potential.

Abstract:

ABSTRACT This study evaluated the response of carpet grass to pig slurry fertilization in order to estimate the agronomic efficiency and the plant-available nitrogen (N) of such manure. A field test was conducted during two years, following a randomized block design with six replicates of the treatments: 0, 100, 200, 300, 400 and 500 kg N ha-1 year-1, which resulted in 0, 60, 120, 180, 240 and 300 m3 ha-1 (2008/09), and 0, 42, 84, 126, 168 and 210 m3 ha-1 (2009/10), according to the N content of the pig slurry used in each year. These treatments were compared with ammonium nitrate (200 kg N ha-1 year-1), in order to estimate the plant-available nitrogen of the manure for the pasture. Pig slurry doses increased linearly the dry matter yield. In 2008/2009, it was increased from 2,600 (0 kg N ha-1) to 7,718 kg ha-1 (500 kg N ha-1), while in 2009-2010 it ranged from 4,310 (0 kg N ha-1) to 12,321 kg ha-1 (500 kg N ha-1). The average agronomic efficiency of the manurewas 15 kg DM kg-1 N and it was lower than that found with ammonium nitrate (27 kg DM kg-1 N).The estimated plant-available N of the pig slurry was similar between the growing years. The N fraction of this manure available to the pasture was 0.64 (2008-09) and 0.60 (2009-10).

Abstract:

Appropriate weeds control is needed against weeds constraints in field, especially the organic field. With the appropriate management, weeding would benefit the organic field not only in reducing weeds but also in increasing nitrogen (N) availability in organic rice fields. This research aims to observe soil available N changes affected by weeding frequencies in organic paddy fields. Treatments applied were five weeding frequencies (WF) such as 0 WF, 2 WF, 4 WF, 6 WF, and 8 WF, to study the effect of various weeding frequencies on soil total N and available N ( NH4+ and NO3–) in the organic rice field. The soil in the conventional field was analyzed as a comparison to organic field soil. The results showed that soil C and N contents are similar in all treatments. Meanwhile, 6 WF performed the highest soil NH4+ among organic plots (10.36 mg N kg–1) and 8 WF enhanced soil NO3– to the highest average among all plots (10.12 mg N kg–1). The treatment of 6 WF and 8 WF also maintain the increase of soil NH4+ to 51 days after transplanting (DAT), meanwhile 0 WF, 2 WF, and 4 WF decreased after 40 DAT. Water samples from fields inlet-outlet and river showed that NH4+ content found in water sample was higher than NO3–. We concluded that the more frequencies of weeding applied to organic fields potentially preserved soil inorganic N longer, which is very important in supporting rice growth.

Abstract:

We use here the results on the influence graph1 to adapt them for particular cases where additional information is available. In some cases, it is possible to improve the expected randomized complexity of algorithms from O(n log n) to O(n log ⋆ n). This technique applies in the following applications: triangulation of a simple polygon, skeleton of a simple polygon, Delaunay triangulation of points knowing the EMST (euclidean minimum spanning tree).
