Title: Optimisation of raw tooke flour, vital gluten and water absorption in tooke/wheat composite bread, using response surface methodology (Part II)
Abstract: The objective of this study was to optimise raw tooke flour-(RTF), vital gluten (VG) and water absorption (WA) with respect to bread-making quality and cost effectiveness of RTF/wheat composite flour. The hypothesis generated for this study was that optimal substitution of RTF and VG into wheat has no significant effect on baking quality of the resultant composite flour. A basic white wheat bread recipe was adopted and response surface methodology (RSM) procedures applied. A D-optimal design was employed with the following variables: RTF (x1) 0-33%, WA (x2) -2FWA to +2FWA and VG (x3) 0 - 3%. Seven responses were modelled. Baking worth number, volume yield and cost were simultaneously optimized using desirability function approach. Models developed adequately described the relationships and were confirmed by validation studies. RTF showed the greatest effect on all models, which effect impaired baking performance of composite flour. VG and Farinograph water absorption (FWA) as well as their interaction improved bread quality. Vitality of VG was enhanced by RTF. The optimal formulation for maximum baking quality was 0.56%(x1), 0.33%(x2) and -1.24(x3) while a formulation of 22%(x1), 3%(x2) and +1.13(x3) maximized RTF incorporation in the respective and composite bread quality at lowest cost. Thus, the set hypothesis was not rejected. Key words: Raw tooke flour, composite bread, baking quality, response surface methodology, Farinograph water absorption, vital gluten.

Title: Textural and Heavy Minerals Characterization of Coastal Sediments in Ibeno and Eastern Obolo Local Government Areas of Akwa Ibom State – Nigeria
Abstract: Textural characterization and heavy mineral studies of beach sediments in Ibeno and Eastern Obolo Local Government Areas of Akwa Ibom State were carried out in the present study. The main aim was to infer their provenance, transport history and environment of deposition. Sediment samples were collected at the water–sediment contact along the shoreline at an interval of about 3m. Ten samples were collected from study location 1 (Ibeno Beach) and twelve samples were collected from study location 2 (Eastern Obolo Beach). A total of twenty–two samples were collected from the field and brought to the laboratory for textural and compositional analyses. The results showed that the value of graphic mean size ranged from 1.70Ф to 2.83Ф, sorting values ranged from 0.39Ф – 0.60Ф, skewness values ranged from -0.02 to 0.10 while kurtosis values ranged from 1.02 to 2.46, indicating medium to fine grained and well sorted sediments. This suggested that the sediments have been transported far from their source. Longshore current and onshore–offshore movements of sediment are primarily responsible in sorting of the heavy minerals. The histogram charts for the different samples and standard deviation versus skewness indicated a beach environment of deposition. This implies that the sediments are dominated by one class of grain size; a phenomenon characteristic of beach environments. The heavy mineral assemblages identified in this research work were rutile, zircon, tourmaline, hornblende, apatite, diopside, glauconite, pumpellyite, cassiterite, epidote, garnet, augite, enstatite, andalusite and opaque minerals. The zircon-tourmaline-rutile (ZTR) index ranged from 47.30% to 87.00% with most of the samples showing a ZTR index greater than 50%. These indicated that the sediments were mineralogically sub-mature and have been transported far from their source. The heavy minerals identified are indicative of being products of reworked sediments of both metamorphic (high rank) and igneous (both mafic and sialic) origin probably derived from the basement rocks of the Oban Massif as well as reworked sediments of the Benue Trough. Therefore, findings from the present study indicated that erosion, accretion, and stability of beaches are controlled by strong hydrodynamic and hydraulic processes.

Title: On-Farm Crop Species Richness Is Associated with Household Diet Diversity and Quality in Subsistence- and Market-Oriented Farming Households in Malawi
Abstract: BACKGROUND On-farm crop species richness (CSR) may be important for maintaining the diversity and quality of diets of smallholder farming households. OBJECTIVES The objectives of this study were to 1) determine the association of CSR with the diversity and quality of household diets in Malawi and 2) assess hypothesized mechanisms for this association via both subsistence- and market-oriented pathways. METHODS Longitudinal data were assessed from nationally representative household surveys in Malawi between 2010 and 2013 (n = 3000 households). A household diet diversity score (DDS) and daily intake per adult equivalent of energy, protein, iron, vitamin A, and zinc were calculated from 7-d household consumption data. CSR was calculated from plot-level data on all crops cultivated during the 2009-2010 and 2012-2013 agricultural seasons in Malawi. Adjusted generalized estimating equations were used to assess the longitudinal relation of CSR with household diet quality and diversity. RESULTS CSR was positively associated with DDS (β: 0.08; 95% CI: 0.06, 0.12; P < 0.001), as well as daily intake per adult equivalent of energy (kilocalories) (β: 41.6; 95% CI: 20.9, 62.2; P < 0.001), protein (grams) (β: 1.78; 95% CI: 0.80, 2.75; P < 0.001), iron (milligrams) (β: 0.30; 95% CI: 0.16, 0.44; P < 0.001), vitamin A (micrograms of retinol activity equivalent) (β: 25.8; 95% CI: 12.7, 38.9; P < 0.001), and zinc (milligrams) (β: 0.26; 95% CI: 0.13, 0.38; P < 0.001). Neither proportion of harvest sold nor distance to nearest population center modified the relation between CSR and household diet diversity or quality (P ≥ 0.05). Households with greater CSR were more commercially oriented (least-squares mean proportion of harvest sold ± SE, highest tertile of CSR: 17.1 ± 0.52; lowest tertile of CSR: 8.92 ± 1.09) (P < 0.05). CONCLUSION Promoting on-farm CSR may be a beneficial strategy for simultaneously supporting enhanced diet quality and diversity while also creating opportunities for smallholder farmers to engage with markets in subsistence agricultural contexts.

Title: Comparative Assessment of Iodine Content of Commercial Table Salt Brands Available in Nigerian Market
Abstract: Iodine deficiency disorders (IDD) has been a major global public health problem threatening more than 2 billion people worldwide. Considering various human health implications associated with iodine deficiency, universal salt iodization programme has been recognized as one of the best methods of preventing iodine deficiency disorder and iodizing table salt is currently done in many countries. In this study, comparative assessment of iodine content of commercially available table salt brands in Nigerian market were investigated and iodine content were measured in ten table salt brands samples using iodometric titration. The iodine content ranged from 14.80 mg/kg – 16.90 mg/kg with mean value of 15.90 mg/kg for Sea salt; 24.30 mg/kg – 25.40 mg/kg with mean value of 24.60 mg/kg for Dangote salt (blue sachet); 22.10 mg/kg – 23.10 mg/kg with mean value of 22.40 mg/kg for Dangote salt (red sachet); 23.30 mg/kg – 24.30 mg/kg with mean value of 23.60 mg/kg for Mr Chef salt; 23.30 mg/kg – 24.30 mg/kg with mean value of 23.60 mg/kg for Annapurna; 26.80 mg/kg – 27.50 mg/kg with mean value of 27.20mg/kg for Uncle Palm salt; 23.30 mg/kg – 29.60 mg/kg with mean content of 26.40 mg/kg for Dangote (bag); 25.40 mg/kg – 26.50 mg/kg with mean value of 26.50 mg/kg for Royal salt; 36.80 mg/kg – 37.20 mg/kg with mean iodine content of 37.0 mg/kg for Abakaliki refined salt, and 30.07 mg/kg – 31.20 mg/kg with mean value of 31.00 mg/kg for Ikom refined salt. The mean iodine content measured in the Sea salt brand (15.70 mg/kg) was significantly P < 0.01 lower compared to those measured in other table salt brands. Although the iodine content of Abakaliki and Ikom refined salt exceed the recommended value, it is clear that only Sea salt brand falls below the World Health Organization (WHO) recommended value (20 – 30 mg/kg), while the remaining table salt samples are just within the range. The results obtained have revealed that 70 % of the table salt brands were adequately iodized while 30 % of the table salt brands were not adequately iodized and provided baseline data that can be used for potential identification of human health risks associated with inadequate and/or excess iodine content in table salt brands consumed in households in Nigeria.

Title: Reduced monocytic human leukocyte antigen-DR expression indicates immunosuppression in critically ill COVID-19 patients
Abstract: BACKGROUND: The cellular immune system is of pivotal importance with regard to the response to severe infections. Monocytes/macrophages are considered key immune cells in infections and downregulation of the surface expression of monocytic human leukocyte antigen-DR (mHLA-DR) within the major histocompatibility complex class II reflects a state of immunosuppression, also referred to as injury-associated immunosuppression. As the role of immunosuppression in coronavirus disease 2019 (COVID-19) is currently unclear, we seek to explore the level of mHLA-DR expression in COVID-19 patients. METHODS: In a preliminary prospective monocentric observational study, 16 COVID-19–positive patients (75% male, median age: 68 [interquartile range 59–75]) requiring hospitalization were included. The median Acute Physiology and Chronic Health Evaluation-II (APACHE-II) score in 9 intensive care unit (ICU) patients with acute respiratory failure was 30 (interquartile range 25–32). Standardized quantitative assessment of HLA-DR on monocytes (cluster of differentiation 14+ cells) was performed using calibrated flow cytometry at baseline (ICU/hospital admission) and at days 3 and 5 after ICU admission. Baseline data were compared to hospitalized noncritically ill COVID-19 patients. RESULTS: While normal mHLA-DR expression was observed in all hospitalized noncritically ill patients (n = 7), 89% (8 of 9) critically ill patients with COVID-19–induced acute respiratory failure showed signs of downregulation of mHLA-DR at ICU admission. mHLA-DR expression at admission was significantly lower in critically ill patients (median, [quartiles]: 9280 antibodies/cell [6114, 16,567]) as compared to the noncritically ill patients (30,900 antibodies/cell [26,777, 52,251]), with a median difference of 21,508 antibodies/cell (95% confidence interval [CI], 14,118–42,971), P = .002. Reduced mHLA-DR expression was observed to persist until day 5 after ICU admission. CONCLUSIONS: When compared to noncritically ill hospitalized COVID-19 patients, ICU patients with severe COVID-19 disease showed reduced mHLA-DR expression on circulating CD14+ monocytes at ICU admission, indicating a dysfunctional immune response. This immunosuppressive (monocytic) phenotype remained unchanged over the ensuing days after ICU admission. Strategies aiming for immunomodulation in this population of critically ill patients should be guided by an immune-monitoring program in an effort to determine who might benefit best from a given immunological intervention.

Title: Directing the development of constraint languages by checking constraints on rdf data
Abstract: For research institutes, data libraries, and data archives, validating RDF data according to predefined constraints is a much sought-after feature, particularly as this is taken for granted in the XML world. Based on our work in two international working groups on RDF validation and jointly identified requirements to formulate constraints and validate RDF data, we have published 81 types of constraints that are required by various stakeholders for data applications. In this paper, we evaluate the usability of identified constraint types for assessing RDF data quality by (1) collecting and classifying 115 constraints on vocabularies commonly used in the social, behavioral, and economic sciences, either from the vocabularies themselves or from domain experts, and (2) validating 15,694 data sets (4.26 billion triples) of research data against these constraints. We classify each constraint according to (1) the severity of occurring violations and (2) based on which types of constraint languages are able to express its constraint type. Based on the large-scale evaluation, we formulate several findings to direct the further development of constraint languages.

Title: The New DBpedia Release Cycle: Increasing Agility and Efficiency in Knowledge Extraction Workflows
Abstract: Abstract Since its inception in 2007, DBpedia has been constantly releasing open data in RDF, extracted from various Wikimedia projects using a complex software system called the DBpedia Information Extraction Framework (DIEF). For the past 12 years, the software received a plethora of extensions by the community, which positively affected the size and data quality. Due to the increase in size and complexity, the release process was facing huge delays (from 12 to 17 months cycle), thus impacting the agility of the development. In this paper, we describe the new DBpedia release cycle including our innovative release workflow, which allows development teams (in particular those who publish large, open data) to implement agile, cost-efficient processes and scale up productivity. The DBpedia release workflow has been re-engineered, its new primary focus is on productivity and agility , to address the challenges of size and complexity. At the same time, quality is assured by implementing a comprehensive testing methodology. We run an experimental evaluation and argue that the implemented measures increase agility and allow for cost-effective quality-control and debugging and thus achieve a higher level of maintainability. As a result, DBpedia now publishes regular (i.e. monthly) releases with over 21 billion triples with minimal publishing effort .

Title: Expanding horizons in historical linguistics with the 400-million word Corpus of Historical American English
Abstract: The Corpus of Historical American English (COHA) contains 400 million words in more than 100,000 texts which date from the 1810s to the 2000s. The corpus contains texts from fiction, popular magazines, newspapers and non-fiction books, and is balanced by genre from decade to decade. It has been carefully lemmatised and tagged for part-of-speech, and uses the same architecture as the Corpus of Contemporary American English (COCA), BYU-BNC, the TIME Corpus and other corpora. COHA allows for a wide range of research on changes in lexis, morphology, syntax, semantics, and American culture and society (as viewed through language change), in ways that are probably not possible with any text archive (e.g., Google Books) or any other corpus of historical American English.
