Abstract
Objective The aim was to clarify the physical properties of five different root canal sealers used as retrograde filling materials on the resected root apex following apicoectomies.Materials and Methods Apical resection was performed on 100 canals of 50 maxillary premolars in slaughtered pigs. The root end of 24 canals were retrogradely filled with Diaket ™, 37 root canals with Super-EBA ™ including 18 with Super-EBA ™ Regular and 19 with Super-EBA ™ fast, 20 canals with ProRoot® MTA and 19 canals with AH-Plus ™. For quantitative examination, scanning electron microscope (SEM) analysis and for qualitative examination microradiography was performed.Results Diaket ™ achieved the best results with an overall average of 4.872 microns gap value. The mean values of marginal gap widths of AH - Plus ™ and Super - EBA ™ were almost the same magnitude 8.044 microns and 9.951 microns respectively, followed by Super - EBA ™ Regular with 11,560 microns. Highest marginal gap value was detected in ProRoot® MTA with 18.343 microns (p < 0.001) .Conclusion According to the limited knowledge of the current in vitro study Diaket ™ achieved the best results compared to the other materials. Additional clinical studies with long term follow up period might help to determine the most appropriate root-end filling material.Clinical Relevance Among five different root canal sealers used as retrograde filling materials, in terms of its marginal integrity and material properties, Diaket ™ can be referred as the most suitable material for retrograde obturation.

Abstract
Background The purpose of this study was to determine if gas tension and acidity levels could serve as biomarkers of pulp inflammatory status in the primary dentition. Methods The present study evaluated acidity level and blood partial pressures of O 2 and CO 2 collected from vital pulp chambers of 84 primary molars with deep carious lesions encroaching the pulp. Teeth were treated with pulpotomy or pulpectomy based on clinical judgement after excision of the coronal pulp tissue. Pulpectomy was performed when positive history of symptoms, difficulty in obtaining hemostasis and/or dark purple blood were present. Using a glass capillary, pulp chamber bleeding was collected and within ten minutes a neonate Astrup test was performed to determine blood gas module pH, pCO 2 , and pO 2 . Results Eighty-four children with one affected tooth participated in the study (37 girls and 47 boys). Age ranged between 3.5 to 11-years (average: 5.3 years). Seventy-one (84%) were treated with the aid of inhalation analgesia, conscious sedation or general anesthesia. Pulpotomy was performed on 51 teeth (61%). Teeth undergoing pulpectomy revealed significant higher level of CO 2 partial pressure (P<0.05) and acidity level values (pH) were also lower in teeth with pulpectomy (P>0.05). Conclusions Higher pCO 2 levels and lower pH were found in pulps needing pulpectomy.

Abstract
Background Chronic pain in HIV-positive patients is a serious health problem that limits patients’ normal functioning both somatically and psychologically. The current state of knowledge on the topic is insufficient, with the underlying causes of this pain unexplained.Methods During their routine visit patients were asked to fill in a general information form and the Alcohol Use Disorders Identification Test Consumption (AUDIT-C) form. All patients reporting any pain were additionally asked to fill in the Brief Pain Inventory (BPI) form and were subject to a brief examination performed by a physician who afterwards completed a Douleur Neuropathique en 4 Questions form (DN4). Logistic regression models were used to identify factors associated with chronic pain occurrence.Results A total of 196 HIV-positive subjects, 96 (48.9% of the study group) of subjects reporting pain within the week prior to enrollment. The reported pain was mostly (75%) limited to a single area of the body (most commonly to the lower limbs). Pain duration was reported to be >6 months previous to study enrollment by 57 subjects (59.4% of those reporting pain). Most subjects were undergoing combination antiretroviral therapy (cART).Conclusions The prevalence of chronic pain in the studied population of HIV-positive Polish patients was high in comparison with other HIV-positive and HIV-negative patient populations. The most prominent risk factor for chronic pain in the study group was age, which poses an important clinical and epidemiological problem due to the aging of the HIV-positive population. It is imperative to develop cooperation protocols for specialist HIV treatment clinics, pain treatment clinics, and rehabilitation units.

Published: October 2019

Precision agriculture requires an understanding of yield variability. The objectives of this study were to (i) document the temporal and spatial variability of corn (Zea mays L.) silage yields on dairy farms in New York, and (ii) derive farm‐based management zones that account for both types of variability. Silage yield data from 847 fields (9084 ha; six farms) were collected by yield monitoring systems between 2015 and 2017. Raw yield data were cleaned of errors via a standardized postharvest data cleaning protocol. The whole‐farm area‐weighted average yield across years and the temporal SD of yield across years for fields with 3 yr of data were used to divide each field into 10‐ by 10‐m grid‐cells. Each grid‐cell was assigned a quadrant (Q), with Q1 and Q4 having consistently higher and lower yield than the farm average yield, respectively; Q2 having variable but higher yield than the farm average; and Q3 having variable and lower yield than the farm average. The evaluation showed variability in average yield per farm, yield per field, and within‐field yield, in addition to variability across years. Spatial and temporal variability were uncorrelated, suggesting that management zones need to consider both spatial and temporal variability. The area per farm classified as variable (Q2 and Q3) ranged from 30 to 44%, illustrating the importance of implementing precision agriculture technologies and in‐season management adjustments. Research is needed to determine the optimum number of zones per farm and the number of crop years to include in developing yield stability zones.Core Ideas

Corn silage yield monitors collect relevant yield data for dairy farmers.
Management zones can be developed from yield stability maps.
Both temporal and spatial variability are important factors to consider.
A yield‐stability‐based approach can generate precision management zones.

Published: October 2019

Canada thistle (Cirsium arvense L.) growing in spring wheat (Triticum aestivum) is difficult to control for several reasons. First, it is a perennial weed that has an extensive root system. Second, the cash‐crop wheat prevents the use of many chemicals, and third, Canada thistle is becoming resistant to many single action herbicides. The objective of this study was to evaluate the effect of postemergence herbicide applications on Canada thistle control growing in a spring wheat field. Replicated studies conducted in Russia between 2015 and 2017 evaluated the impact of different herbicide mixtures on Canada thistle control. The formulated mixtures of (iodosulfuron/mesosulfuron/antidote mefenpyr‐diethyl) mixed with triasulfuron and metsulfuron and triasulfuron + metsulfuron increased wheat yields 48 to 60% and provided the greatest (>85%) Canada thistle suppression in all experiments. Generally, (aminopyralid/florasulam), triasulfuron and (2,4‐D/florasulam) provided little control. It can be concluded that in all treatments, the herbicide mixtures did not provide 100% control, and therefore care must be used to prevent the creation of herbicide resistant Canada thistle.Core Ideas

Formulated mixtures of herbicides containing (iodosulfuron/mesosulfuron/antidote mefenpyr‐diethyl) and triasulfuron plus metsulfuron provided the most effective Canada thistle suppression.
Canada thistle was better controlled at the early stage of spring wheat.
Herbicide mixtures containing multiple modes of action was more effective than a single mode of action herbicide in the control of Canada thistle in wheat.
Genetic Improvement in Resistance to Striga in Tropical Maize Hybrids
Authors: Menkir Abebe , Meseka Silvestro 
Published: October 2019

ABSTRACTStriga hermonthica (Del.) Benth parasitizes maize (Zea mays L.) in sub‐Saharan Africa, causing yield losses of up to 100% under severe infestation. Hybrid maize breeding for polygenic resistance to Striga has been undertaken at the International Institute of Tropical Agriculture (IITA) since the 1980s. This study was conducted to estimate genetic gain in grain yield and associated traits in a set of 32 maize hybrids developed over three breeding periods under artificial Striga‐infested and noninfested conditions for 4 yr. The results of regression analyses showed a linear annual yield gain of 3.2% with a mean increase of 93.7 kg ha−1 yr−1 under Striga infestation, much of which was primarily associated with significant reductions of 2.6% yr−1 in Striga damage symptoms and 5.5% yr−1 in the number of emerged parasites at 10 wk after planting. Other traits associated with grain yield including plant height and number of ears per plant increased, whereas silking days, ear aspect, and anthesis–silking interval decreased over time. On average, hybrids developed after the 1990s yielded 64% more and displayed 61% less parasite emergence and 30% less parasite damage at 10 wk after planting compared with hybrids developed before the 1990s. These improvements were achieved with increases in grain yield, early silking, reduced anthesis–silking interval, and resistance to ear rot under noninfested conditions. The trends in breeding progress achieved during this time period appear to be in the right direction, highlighting the potential that exists to further reduce yield losses to S. hermonthica in hybrids.

Abstract
Green roofs are a sustainable, low-impact development technique. They can reduce peak stormwater runoff and runoff volume and improve the quality of runoff from individual buildings and developments, which can lower the risk of frequent urban flooding and improve the quality of receiving waters. Few studies have compared different types of green roof models under the same rainfall intensities; thus, in this study, the predictions of a non-linear storage reservoirs model, Storm Water Management Model (SWMM), and a physical process model (HYDRUS-1D) were discussed. Both models were compared against measured data obtained from a series of laboratory experiments, designed to represent different storm categories and rainfall events. It was concluded that the total runoff of the SWMM model is always less than that of HYDRUS-1D. The maximum flowrate of the SWMM model is more than that of HYDRUS-1D during all events.

Published: October 2019

Permeable reactive barrier column tests were performed to investigate whether anaerobic bacteria in sheep manure could help remove As from groundwater. One column served as a control and was packed with zero-valent iron (ZVI), compost leaf, wood chips, glass beads, and gravel, after which it was sterilized. The other (‘inoculated column’) was packed with the same ingredients, with the addition of sheep manure as a source of anaerobic bacteria. Simulated As-contaminated groundwater was prepared based on groundwater samples from Sumbawa Island, Indonesia, but with the arsenic concentration adjusted to 50 mg/L. The inoculated column was found to remove As more effectively from the simulated groundwater than the sterilized one. A gradual decrease in sulfate concentration was observed in the inoculated column at the rate of 0.26 mmol of sulfate/L/day, suggesting that there was sulfate-reducing activity in the microbial population. In addition, the sulfur isotope ratio showed -4.3 (‰) and 0.2 (‰) in influent and effluent, respectively, indicating that sulfate-reducing bacteria (SRB) consumed δ32S preferentially. Using population size estimates from the most probable number (MPN) method, the population of SRB was found to increase with distance traveled in the column. Profiling the community composition of the bacteria in different fractions of the inoculated column using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) on 16S rRNA sequences suggested that a majority of bacteria were various Clostridium species and one species of Proteobacteria, Geobacter metallireducens GS-15. Some of them may contribute to the removal of arsenic.Keywords: Sheep manure, zero valence iron, arsenic, immobilization, sulfate-reducing bacteria
