A well-structured root system is essential to ensure optimal plant growth and yield. Two experiments were conducted to determine the effects of plant growth promoting rhizobacteria (PGPR) on the root system of okra plant. These experiments were arranged with a completely randomized design. The first experiment was conducted in the growth chamber with 8 different bacterial isolates consisting of Methylobacterium sp., Bacillus sp., Bacillus methylotrophicus, Flavobacterium tirrenicum, Providencia stuartii, Azotobacter vinelandii, Methylocystis parvus and PGPR consortium. The second experiment was conducted in the greenhouse and examined the effects of four poultry manure rates, i.e. 0, 6, 12 and 18 ton ha-1, or equivalent to 0, 75, 150 and 225% of recommended rates and how these are altered with the presence or absence of PGPR. The results of the experiments showed that, PGPR significantly improved root architecture; the number and length of lateral roots was increased by 242.86% and 777.79% respectively, as well as the dry weight of the roots and shoots of okra plant by 236.36% and 333.33%, respectively. Moreover applying 150% (12 t.ha-1) of the recommended rate of poultry manure enriched with PGPR was found to be most effective in terms of improving the growth and root attributes of okra plants.

In this study, we report the synthesis and characterization of boron nitride nanosheets (BNNSs), and their application as an adsorbent to remove the cationic dyes methylene blue (MB) and rhodamine B (RhB) from contaminated water. The synthesized adsorbent was characterized by high-resolution transmission electron microscopy (HR-TEM), field emission electron microscopy (FE-SEM), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR) and nitrogen adsorption–desorption isotherm. Detailed experiments and analysis were performed on various molar ratios of boron and nitrogen precursors (1:5 to 1:48) to achieve maximize specific surface area of BNNSs. Among all, the samples synthesized with boric acid and urea (1:30) dissolved in water and methanol produced maximum specific surface area (1801.9 m2 g−1). Further, the adsorption study was performed in batches by investigating various adsorption parameters such as effect of pH, contact time, adsorbent dose and adsorption isotherm. The pH study revealed that optimum value was found to be at pH 8. It was found through the kinetic study that pseudo-second-order (PSO) kinetic model was followed by the adsorbent during the adsorption of both the dyes. Further, the adsorption isotherm data well fitted with Langmuir isotherm model. The maximum adsorption capacities of MB and RhB were found to be 333.33 and 312.5 mg g−1, respectively. This demonstrates the potential of BNNSs as novel adsorbent for treatment of dye-contaminated water.

Potential of granulated modified nanozeolites Y for MTBE removal from aqueous solutions: Kinetic and isotherm studies Adsorption of methyl tert-butyl ether (MTBE) from aqueous solutions by granulated modified nanozeolites Y was investigated. Nanozeolite Y powders were converted into granulated zeolites and subsequently modified with two cationic surfactants (20 mmol/dm3), to be used as adsorbent. Granulated nanozeolites were characterized by BET surface area analysis, elemental analysis and X-ray diffractometer. -Hexade-cyltrimethylammonium (HDTMA-Cl) modified granulated zeolite had more effective performance than N-cetylpyridinium bromide (CPB) modified granulated zeolite. The most conventional adsorption isotherms and kinetic models were applied to describe MTBE adsorption and reaction dynamic, respectively. The equilibrium sorption data fitted the Langmuir 2 isotherm model and the kinetic study was followed the pseudo-second-order model. The maximum adsorption capacities for HDTMA-Cl modified zeolite and CPB modified granulated zeolite were 333.33 and 142.8 mg/g, respectively as calculated by the Langmuir model. This study demonstrated that the removal of mtbe by granulated modified nanozeolites Y is a promising technique.

This paper presents an 8-bit configurable time-interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC). By using a mode selection circuit, four modes of sampling rate are provided: Single channel at 333.3 MS/s, 2-channel at 666.7 MS/s, 3-channel at 1 GS/s and 6-channel at 2 GS/s. An on-chip delay-locked loop (DLL) uniformly generates six-phase clock with 20% duty cycle, and the timing errors are reduced to a tolerable range. In low sampling rate modes, the corresponding sampling switches and comparators in the idle sub-ADCs are shut down to save power consumption. Based on the 65-nm CMOS technology, the post-layout simulation results show that at 1.2 V supply, the proposed ADC consumes 8.6, 10.9, 13.1 and 19.9 mW under different modes. With an ENOB of 7.92, 7.34, 7.01 and 6.37 bit, this results in a FOM of 106.6, 100.9, 101.6 and 120.3 fJ/conversion-step respectively.

According to the characteristics of asphalt pavement, a kind of nano-TiO2 photocatalytic coating was prepared by using the emulsified asphalt as the carrier. All of its properties met the technical requirements. An exhaust gas degradation test device and its test steps were developed. The evaluation indexes, cumulative degradation rate, and degradation efficiency, were put forward. From the two aspects of the nano-TiO2 content in photocatalytic coatings and the spraying amount of photocatalytic coatings in the surface of slabs (300 mm × 300 mm), the exhaust gas degradation effects, the performances of skid resistance, and the water permeability of asphalt mixture were analyzed. The test results showed that the cumulative degradation rate of exhaust gas was better when nano-TiO2 content was increased in the range of 0–8% and the spraying amount was changed in the range of 0–333.3 g/m2. In practical engineering applications, the anti-skid performance of asphalt pavement can be satisfied when the spraying amount of photocatalytic coating was limited to under 550 g/m2. The spraying amount of nano-TiO2 photocatalytic coating had little effect on the water permeability of the asphalt mixture. Therefore, 8% nano-TiO2 content in the coating and a 400 g/m2 spraying amount were finally recommended based on the photocatalytic properties, as well as for economic reasons.

Background:Giant cell arteritis is the most common chronic systemic vasculitis in older adults. Permanent visual loss is the most concerning complication can occur in up to 20% of patients (1). Diagnosis is based on a combination of clinical findings, laboratory evidence of inflammatory markers, and temporal artery biopsy (TAB) confirming histologic evidence of inflammation. There are no definitive markers of the disease when TAB is negative.Objectives:The objective of this study was to illustrate the clinical features of subjects suspected with GCA evaluated at the Dallas Veterans Affairs Medical Center (VAMC) and identify those features that would differentiate between TAB positive GCA, TAB negative GCA and non-GCA patients.Methods:This retrospective study searched the Dallas VAMC database for subjects between January of 2010 until December 2019 with ICD-9 and ICD-10 entry code for GCA. Based on the 1990 ACR clinical classification criteria for GCA, suspected patients were classified as TAB positive GCA, TAB negative GCA and non-GCA. Subjects with incomplete data needed for classification were excluded. Group comparisons were performed with Fisher’s exact test for categorical variables and the Mann-Whitney test for continuous variables.Results:One-hundred and sixty-nine subjects had ICD-9/10 entry code for GCA. Ophthalmology was the specialty who did the initial evaluation in 46% of the suspected cases. Seventy-one patients were excluded due to incomplete data. Of the remaining 98 patients, 42 (42.9%) were diagnosed with GCA out of which 10 patients had a positive TAB. Seventy-six percent of patients diagnosed with GCA had negative temporal artery biopsies. In 56 (57.1%) patients GCA was ruled out (Figure 1). New-onset headache was the predominant symptom suggestive of GCA affecting 88.9% TAB positive and 100% of TAB negative cases compared to 56.6% of non-GCA patients (p< 0.001), followed by scalp tenderness in 33.3%, 58.1% and 10.9%, respectively (p< 0.001), jaw claudication in 57.1%, 34.5% and 14.9% (p=0.021), and elevated sedimentation rate in 33%, 65.6% and 33% (p=0.013) (Table 1). Polymyalgia rheumatica was present in 28.6% and 21.7% of patients diagnosed with GCA compared to zero percent in non-GCA cases (p=0.017). More than 30% of patients with GCA had normal acute phase reactants in this cohort.Table 1.Comparison of demographics and clinical features of patients with suspected GCAGCA TAB Positive (n=10)GCA - TAB Negative (n=32)non-GCA (n=56)n%n%n%pAge (mean/sd)71.3 (7.8)67.3 (8.1)67.3 (8.9)0.367Male99030/3293.851/5691.10.885Clinical findingsNew onset headache8/988.932/3210030/5356.6<0.001Visual symptoms9/109022/3268.842/5477.80.351Jaw claudication4/757.110/2934.57/4714.90.021PMR2/728.65/2321.70/3000.017Scalp tenderness2/633.318/3158.15/4610.9<0.001Fever0/505/2321.72/355.70.117ESR > 501/333.321/3265.618/5433.30.013CRP > 101/333.35/3016.76/5411.10.473Anemia (hemoglobin < 12 g/ dl)2/728.615/3246.921/5240.40.642Thrombocytosis (platelets >400)2/728.63/329.44/517.80.228Conclusion:There is clinical heterogeneity within the patients diagnosed with GCA regardless of TAB.

Density and survival of a raccoon (Procyon lotor) population in Rock Creek Park, an urban national park inWashington, D.C., were estimated using mark–recapture and radio-tracking over an 8-year period following the appearance ofthe mid-Atlantic States (Mid-Atlantic) rabies epizootic. Raccoon density ranged from 333.3 to 66.7/km2 , with an overall parkestimate of 125/km2 . This density places the Rock Creek population within the range of other urban and suburban populationsand is many times greater than raccoon densities reported from other habitats. Density was particularly high in one thin spur ofparkland with the smallest ratio of area to urban edge. Raccoon survival rates were high except among juveniles during therabies epizootic. Data on rabies prevalence from Washington, D.C., indicate a cycle with peaks in 1983 during the initialepizootic and again in 1987 and 1991, a pattern similar to that seen in other carnivores and in rabies models. We found evidenceof decreased raccoon density during and after the 1987 rabies resurgence relative to the years following the original epizootic,when rabies prevalence was low. While hunting and trapping represent a major mortality factor for many rural raccoonpopulations, urban and suburban populations and protected populations may frequently be subject to epizootics of diseasessuch as canine distemper and rabies, even years after initial contact with a disease.

Background We conducted this study to assess preliminary 2-year safety outcomes of an implant-based augmentation mammaplasty using the BellaGel® SmoothFine in the context of the first Korean case of a medical device fraud. Methods Our clinical series of the patients (n = 579; 1,158 breasts) received augmentation using the BellaGel® SmoothFine, Naturgel™, Motiva Ergonomix™, Eurosilicone Round Collection™, Natrelle® INSPIRA™, Natrelle® 410, Mentor® MemoryGel Xtra or Microthane®. The patients were evaluated for incidences of postoperative complications and Kaplan-Meier survival and hazards. Results Overall, there were a total of 101 cases (17.4%) of postoperative complications; these include 31 cases (5.4%) of shape deformity, 21 cases (3.6%) of CC, 18 cases (3.1%) of early seroma, 8 cases (1.4%) of infection, 5 cases (0.9%) of early hematoma, 1 case (0.2%) of delayed hematoma, 1 case (0.2%) of rupture and 1 case (0.2%) of ripping. Moreover, there were also 15 cases (2.6%) of other complications. There were significant differences in incidences of postoperative complications between the breast implants from different manufacturers (P = 0.034). The Natrelle® 410 showed the longest survival (333.3±268.2 [141.5–525.1] days). A subgroup analysis showed that there were no significant differences in incidences of postoperative complications between the breast implants (P = 0.831). Moreover, the Natrelle® INSPIRA™ showed the longest survival (223.7±107.1 [-42.3–489.6] days). Conclusions Here, we describe preliminary 2-year safety outcomes of an implant-based augmentation mammaplasty using the BellaGel® SmoothFine in the context of the first Korean case of a medical device fraud.

5511 Background: The benefit of adjuvant CT in NPC is unclear. Administering CT after full-dose CRT presents challenges in treatment compliance and toxicity. Post-RT EBV DNA predicts poor survival and may be a biomarker of subclinical residual disease. We conducted a biomarker driven RCT using EBV DNA to select high risk NPC patients (pts) for adjuvant CT while sparing low risk pts from unnecessary toxicity. Methods: Biopsy proven NPC, AJCC stage IIB-IVB, detectable EBV DNA at 6-8 wks post-RT, no persistent locoregional disease or distant metastasis, ECOG 0 or 1, adequate organ function. Randomised with stratification for primary therapy (RT Vs CRT) and tumor stage (II/III Vs IV) to arm A (adjuvant cisplatin 40 mg/m2 and gemcitabine 1000mg/m2, both given on D1+8 q3w x 6 cycles) or arm B (clinical follow-up). EBV DNA and PET scan were performed before and 6 months after randomization. Primary endpoint was relapse free survival and secondary endpoints included toxicity of adjuvant CT. With a hazard ratio of 2, 100 pts were required with a power of 0.8 and an alpha at 0.05. This safety analysis was approved by DMSC. Results: From 9/2006 to 12/2011, 514 pts consented for EBV DNA screening, 95 with detectable EBV DNA consented for adjuvant study. After work-up, 74 were eligible for randomization (37 to arm A; 37 to arm B). The two arms were well balanced in baseline characteristics. 80% received prior neoadjuvant and/or concurrent CT. Staging: IIB (36.5%), III (29.7%), IVA (18.9%), IVB (14.8%). Five pts refused adjuvant CT after randomization. Overall 65% and 57% completed 5 and 6 cycles respectively. Mean dose intensity (DI): 84% for cisplatin (22.5 mg/m2/wk, range 0.0-26.7), 92% for gemcitabine (612.8 mg/m2/wk, range 333.3-777.8). Treatment related adverse events above CTC G2 were summarized in Table. Conclusions: Delivery of 6 cycles of adjuvant CT is feasible with acceptable toxicity after full dose RT or CRT.
