AbstractAn improved understanding of potential soluble phosphorus (P) loss in run‐off and leachate from agriculturally managed soils presents practical and theoretical challenges. Our study aimed to discover whether modified Morgan extractable P (MMP) can be used to predict water‐soluble P (WSP). We first addressed the relationship between MMP and WSP, and whether MMP is useful for predicting the WSP concentrations demanded by water quality regulations. Secondly, we applied novel soil chemical models to explain why the relationship between MMP and WSP depends upon soil properties. Thirdly, we explain how soil properties relate to potential soluble P loss in situations in which soil is subjected to a wide liquid‐to‐soil ratio (e.g. run‐off and rivers) compared with those with a narrow ratio (e.g. soil porewater). To address these P loss scenarios, 60 agricultural topsoils (0–10 cm) were collected from a mixed‐farming catchment (Lunan catchment, northeast Scotland) and chemically characterized. Theoretical understanding of P solubility was obtained with a P sorption model. The data showed variability in the relationship between MMP and WSP. Modelling shows the MMP versus WSP relationship is nonlinear, depending on several confounding factors (P sorption capacity (PSC), Ca, pH) and the liquid‐to‐soil ratio (L:S) employed for WSP determination. Consequently, the slope of the relationship is not unique but depends subjectively on the set of soils surveyed. MMP versus WSP at large L:S (e.g. in run‐off or rivers) is positively correlated to PSC, whereas at narrow L:S (e.g. porewater) there is a negative correlation with PSC. The study provides new ideas for the interpretation and extrapolation of agronomic soil test data for soils of varied properties and highlights the need to utilize insights from soil chemistry.

BACKGROUNDWith increasing demand for umbilical cord blood units (CBUs) with total nucleated cell (TNC) counts of more than 150 × 107, preshipping assessment is mandatory. Umbilical cord blood processing requires aseptic techniques and laboratories with specific air quality and cleanliness. Our aim was to establish a fast and efficient method for determining TNC counts at the obstetric ward without exposing the CBU to the environment.STUDY DESIGN AND METHODSData from a total of 151 cord blood donations at a single procurement site were included in this prospective study. We measured TNC counts in cord blood aliquots taken from the umbilical cord (TNCCord), from placenta (TNCPlac), and from a tubing segment of the sterile collection system (TNCTS). TNC counts were compared to reference TNC counts in the CBU which were ascertained at the cord blood bank (TNCCBU).RESULTSTNCTS counts (173 ± 33 × 107 cells; calculated for 1 unit) correlated fully with the TNCCBU reference counts (166 ± 33 × 107 cells, Pearson's r = 0.97, p < 0.0001). In contrast, TNCCord and TNCPlac counts were more disparate from the reference (r = 0.92 and r = 0.87, respectively).CONCLUSIONSA novel method of measuring TNC counts in tubing segments from the sterile cord blood collection system allows rapid and correct identification of CBUs with high cell numbers at the obstetric ward without exposing cells to the environment. This approach may contribute to cost efficacy as only CBUs with satisfactory TNC counts need to be shipped to the cord blood bank.

BACKGROUNDOnce a patient has produced a red blood cell (RBC) antibody, there is an increased risk of additional antibody formation after subsequent RBC exposure. Recently, we observed that HLA‐DRB1*15 was overrepresented in 379 multiple RBC antibody responders compared to controls or 562 patients with a single RBC antibody (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.3‐2.3). In this study we evaluated whether the HLA‐DRB1*15 represents a responder phenotype against HLA and/or RBC antigens.STUDY DESIGN AND METHODSHLA‐DRB1*15 frequencies in single and multiple antibody responders were compared between three groups of individuals: 1) those with HLA antibodies, 2) those with RBC antibodies, and 3) those with both RBC and HLA antibodies.RESULTSA total of 3959 immunized patients (female‐to‐male ratio, 2.3) had been HLA‐DRB1 typed. Among the 3275 individuals with HLA antibodies, the frequency of the DRB1*15 phenotype differed significantly from 19.7% in patients with a panel reactivity (PRA) of not more than 20% to 26.9% in patients with PRA of more than 80% (OR, 1.5; 95% CI, 1.2‐1.9). This association between DRB1*15 and multiresponsiveness was mainly due to pregnancy‐induced HLA immunization. In the 257 individuals with RBC and HLA antibodies, the frequency of DRB1*15 was 4.2 times (95% CI, 1.1‐16) higher in those with multiple RBC antibodies and HLA‐PRA of more than 50% compared to only single RBC responders with PRA of less than 20%.CONCLUSIONThe HLA‐DRB1*15 phenotype is associated with broad RBC and HLA immunization.

Background and ObjectivesBlood Centre logistics, staffing and donor scheduling may be optimized if pathogen inactivation (PI) of platelets can be delayed until Day 1, but bacteria may rapidly grow during this time. This study evaluates bacterial PI performed 24 and 30 h after collection.Materials and MethodsPAS‐3 platelet units were collected on the Amicus and subsequently inoculated (3–53 CFU/unit) with 1of 5 transfusion relevant bacterial species (n = 3/organism). Units were then stored for either 24 ± 0·3 or 30 ± 0·3 h at 20–24°C with agitation, subsequently treated with amotosalen and UVA, and stored for 7 days. Samples were taken before and after inactivation, on Days 2, 5 and 7 for BacT/ALERT testing, and on Days 5 and 7 for plate counts.ResultsAll samples from units taken prior to inactivation either demonstrated positive plate culture counts, or, in untreated positive controls, were culture‐positive during storage. All contaminated units treated with amotosalen and UVA 24 after inoculation were culture‐negative on all days tested. With inactivation performed 30 h following inoculation, one of 15 units (1‐of‐3 replicates) was culture‐positive with Klebsiella pneumonia (1 × 109 CFU/ml) by Day 5.ConclusionPhotochemical treatment did not inactivate 1 of 15 units to sterility in apheresis platelets stored in PAS with a 30‐h delay between contamination and treatment, but did inactivate 15 of 15 units with a 24‐h delay.

Background and ObjectivesIn mice, loss of sialic acid resulting in shedding of glycoprotein (GP) Ibα and GPV has been linked to platelet survival. The aim of this study was to determine whether loss of sialic acid and the GPIb‐IX‐V complex contributes to development of the platelet storage lesion (PSL) in human platelet concentrates (PCs).Materials and methodsPCs (stored in plasma (with or without Mirasol treatment); PAS‐C or PAS‐E) were stored at room temperature. Flow cytometry was used to monitor membrane expression of the GPIb‐IX‐V complex, CD62P, surface glycans and PS exposure. The functionality of stored platelets was determined employing aggregometry and ristocetin‐induced VWF binding.ResultsStorage time of PCs in blood banks is limited to 7 days. During this time period, a minor but gradually increasing subpopulation of GPIbα‐negative platelets was observed. Also, ristocetin‐induced VWF binding was impaired in a small population of platelets. Mean surface expression of GPIbα and GPV remained stable until day 9, whereas CD62P expression increased; also a rapid decrease in ADP‐induced aggregation was observed for PAS‐C, PAS‐E and Mirasol‐treated PCs. Upon prolonged storage (>9 days), a slow decline in surface expression of GPIbα and GPV was observed; no major changes were observed in surface sialylation with the exception of Mirasol‐treated platelets.ConclusionIn a small population of stored platelets, changes in GPIbα occur from day 2 onwards. Loss of sialic acid and subsequent shedding of GPIbα and GPV is not an early event during the development of the PSL.

The advantage of oil palm shell (OPS) as coarse aggregate in concrete can be extended to insulation concrete capacity. Thus, this paper will explain the durability of oil palm shell lightweight concrete (OPSLC) for insulation concrete capacity in building. Nine mix designs were developed containing high volume of OPS, which is 30, 32 and 34% from total volume of concrete with three different OPS shapes (raw, crushed and partly crushed). The water absorption and drying shrinkage were examined; besides, thermal conductivity testing that was conducted for confirmation as insulation concrete category. The observation of all the specimens lasted one year for durability performance test and 28 days for thermal conductivity value. The highest water absorption value is 43% from previous study that was designed for structural concrete. Higher OPS volume fraction produced higher air void content and caused water loss and increase of the hydration effects on OPSLC shrinkage. It also affected the microstructure conditions, especially specimens that used 34% of OPS volume fraction which show weak interface bond in cement matrix.

AR Drone 2.0 is a miniature unmanned aerial vehicle used in the field of research. AR Drone 2.0 has a camera and IMU sensors, so it can be used to get visual data from air which hardly done by human. Unmanned aerial vehicle requires GPS (Global Positioning System) so that the pilot can control it remotely as well as to support automatic fly without pilot. While GPS data are supported by AR Drone 2.0 it still needs data conversion process due to the difference in data protocol which is used between the Drone and the GPS. This conversion process required processor or controller to process the data. Integration of GPS with AR Drone using controller also allows drone to run for automatic control. In addition, GPS data will also be sent information of latitude and longitude to computer so that the pilot can determine the current position when AR Drone is flying. The GPS system used for this design can be developed further in the future because it is open source.Â Â

Crash box designs have been developed in order to obtain the optimum crashworthiness performance. Circular cross section is first investigated with one segment design, it rather influenced by its length which is being sensitive to the buckling occurrence. In this study, the crash box with multi-segments design is investigated and the deformation behavior and crash energy absorption are observed. The crash box modelling is performed by finite element analysis on cylindrical crash box with multi segments design. The numbers of crash box segments used in this investigation are two segments, three segments with a sequence diameter and three segments with alternating diameter. The crash test components were impactor, crash box, and fixed rigid base. Impactor and the fixed base material are modelled as a rigid, and crash box material as bilinear isotropic hardening. Crash box length of 100 mm and frontal crash velocity of 16 km/jam are selected. Crash box material of Aluminum Alloy is used. Based on simulation results, it can be shown that three segments crash box with alternating diameter design has the largest crash energy absorption. From deformation pattern has showed that three segments crash box absorbs low energy at the beginning of crashing. Energy absorption start increased at the boundary area of the first, second and three segments as a result of increasing inertia where critical load has increased hence buckling phenomenon could be minimized.

Strengthening of reinforced concrete (RC) continuous beams in shear have received very little attention among researchers even though most existing structures are in the form of continuous condition such as part of a floor-beam system. Therefore, in order to address the gap, a study on shear strengthening and shear repair of reinforced concrete continuous beam using Carbon Fibre Reinforced Polymer (CFRP) strips was conducted [15]. The validation of the experimental results was conducted with a simulation study using a finite element software ATENA v4 [16]. The research variables were number of layers of CFRP strips (one or two layers), wrapping schemes (four sides or three sides) and orientation of CFRP strips (0/90 or 45/135 degree’s). From the analysis of the finite element results, ATENA shows it has successfully simulated the shear behaviour of strengthened and repaired of 2-span continuous RC beams externally bonded by CFRP strips.

Published: May 2016

Broken mesoporous ceramic filter was reutilized by coating with ferric solution through a simple loading method enhanced with heating at a moderate temperature for arsenate uptake from aqueous solution. BET, XRF, XRD, and SEM methods were applied for the adsorbent characterization. The adsorption study was conducted in a batch mode to investigate kinetics, isotherms, and the effect of solution pH and co-existing anions. The pseudo-second order kinetic model well fitted the experimental data (R2 = 0.9997). The maximum arsenate adsorption capacity (2.27 mg/g) was derived from the better described Langmuir isotherm model (R2 = 0.9992). The adsorbent expressed high arsenate adsorption capacity over a pH range of 4-10. The uptake behavior is a favorable and physical adsorption process based on the value of separation factor and mean sorption energy. The presence of co-existing anions decreased the arsenate adsorption capacity in the following order: NO3-< SO42- < PO43-. The new ferric-coated mesoporous ceramic adsorbent could be an effective and low-cost adsorbent for arsenate removal from water.

Rapid growth in construction activities in Kuala Lumpur resulted in increasing of construction waste problems. Construction waste gives a negative impact to the environment, cost, time, productivity and social of the country. This paper studies the challenges of construction waste management faced by the contractors undertake projects in Kuala Lumpur. Eighty five (85) numbers of questionnaires were distributed to various groups of respondents which include main contractors, registered contractor for collection of waste, Kuala Lumpur City Hall (DBKL) officers and Solid Waste Corporation (SWCorp) officers. Spearman’s rank correlation coefficient analysis, mean ranking analysis, Kruskal-Wallis test, and factor analysis are among the analysis used in this study. In addition correlation test were also conducted to establish the correlation between the factors. The result shows that the factor influenced in successful implementation of Construction waste management (CWM) for DBKL projects are internal factor, management factors, local authority factor and law regulation. The findings also show that the barrier in implementing CWM in DBKL projects is due to the lack of authority to monitor the management of construction waste on site. The findings of this study highlight the scenario of the current CWM for projects in Kuala Lumpur and thus, provide the recommendation in improving the CWM in Kuala Lumpur.

Quadricuspid aortic valve (QAV) is an anatomic valvular variant, with a prevalence of 0.008% to 0.033% in the general population, and 1.46% in patients that undergo aortic valve replacement. The QAV can be an isolated valvular abnormality or associated with other congenital heart defects. In this article, we present three of the few reported cases of QAV in the Hispanic population, all of which were asymptomatic and without evidence of hemodynamic alterations or other associated heart defects. Additionally a literature review is provided.

Aim: To evaluate the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) as a method for diagnosing pancreatic lesions with regard to the ductal pancreatic carcinoma and the differentiation of neoplastic from non-neoplastic lesions. Material and methods: Relevant studies published by September 6, 2015 were retrieved from PubMed, Embase, and Cochrane Central Trials databases. The articles included were mainly based on the following criteria: use of CEUS as the diagnostic tool, and the use of histology as the reference method. Two independent reviewers inspected all these papers to confirm the matching of the inclusion criteria. One reviewer with methodological expertise extracted the data from the included studies. Sensitivity, specificity and diagnostic odds ratio (DOR) were used to obtain overall estimates. Results: Eighteen studies out of 734 articles initially identified met the inclusion criteria. The primary study objective with respect to ductal adenocarcinoma was verified in 15 studies. The pooled estimate of CEUS sensitivity for the differential diagnosis of duct adenocarcinomas was 0.90 (95 % CI, 0.89–0.92), and the specificity was 0.88 (0.84-0.90). The pooled estimate for DOR was 56.38 (29.91-106.33). The area under the curve under the summary receiver operating characteristic (SROC) was 0.95. 12 out of 18 studies examined CEUS sensitivity and the average specificity with regard to the secondary study objective, distinguishing between neoplastic lesions and non-neoplastic lesions, were 0.95 (0.94-0.96) and 0.83 (0.77–0.87). The pooled estimate for DOR was 73.25(45.31-118.43). The area under the SROC curve was 0.96.Conclusions: CEUS is a promising, reliable modality for the differential diagnosis of pancreatic adenocarcinoma in patients with pancreatic mass lesions. The presence of a hypoenhanced lesion was a sensitive predictor of pancreatic adenocarcinomas. It seems to be a useful tool in clinical practice.
