Effects of Anaerobically Digested Poultry Manure on Soil Phosphorus Adsorption and Extractability

Research in the past has indicated that large additions of animal manures to soil can reduce soil P adsorption and increase P extractability. However, application rates used in many studies are unrealistic with respect to crop fertilization and land disposal due to excessive quantities of N applied with the manures. The objective of this study was to evaluate effluent from a poultry manure anaerobic digester applied to a Hayesville loam soil (clayey, oxic, mesic, Typic Hapludult) on soil P adsorption and extractability after three incubation periods (0, 30 and 90 d). Effluent solids were applied at rates corresponding to 753 through 7530 mg N/kg soil. Langmuir equation parameters (from least square fitted data: R squared more than 0.98) were used as a basis to compare the influence of treatments on P adsorption properties of the soil. The P adsorption maxima parameter was not influenced by any of the effluent treatments. The parameter related to P bonding energy of the soil was reduced 33 and 41%, respectively, by mid and high rate effluent applications. A similar reduction was not observed for the low rate treatment, which corresponded to fertilizer application of 100 mg N/kg soil. Extractable soil P increased in amore » predictable manner with increased effluent solids application for all three incubation periods. These increases in extractable P could be described by linear regression equations. The slopes of these lines indicate that a one gram addition of effluent solids to one kg soil accounts for increases in extractable P of 3 to 6 mg/kg. 9 references. « less
AMMONOLYSIS OF URONIC ESTER GROUPS IN BIRCH XYLAN

Solvent-extracted white birch, kept near 20° in liquid ammonia under pressure for 72 h and then extracted with methanol to remove acetamide, retained 0.25% of amide nitrogen. Extraction of the very finely ground residual wood with hot water yielded 21% as a 4-O-methylglucuronoxylan containing 0.53% of amide nitrogen. Alkaline hydrolysis removed the amide absorption in the infrared and restored the normal xylan spectrum. These results, supported by various control experiments, showed that amide groups in the ammonia-treated wood were derived from lactone or ester groups in the original 4-O-methylglucuronoxylan. Some of the uronic acid groups in the native wood presumably existed as ester crosslinks.
Perspectives of Healthy Eating Environment on Campus: A Qualitative Study in a Private University in Ankara, Turkey

Aim: Universities provide food service to not only students, but also to their employees from all levels. However, the limited literature persists in terms of evaluating the campus food environment by different kinds of stakeholders. Therefore, this study aims to understand and conceptualize the experiences and perceptions of students and university staff towards campus food environment. Subjects and Methods: We conducted six focus groups among sixty-four people that belong to a private university in Ankara with the following roles; (i) Turkish and international students, (ii) Academic staff, (iii) Administrative staff, and (iv) Support staff. Thematic analyses were conducted by NVivo software and triangulation is done by evaluating a monthly lunch menu of the cafeteria with Nutrient Rich Food Index 9.3 (NRF 9.3) nutrient profiling model. Results: Qualitative analyses revealed that participants were aware of the nutritional importance of food services and consequences of consuming meals, foods, and beverages with low nutritional value. Nutritional value of the food was among the most important drivers of food selection and participants demanded menus to be planned by a dietitian. The seven overarching themes that were determined within the qualitative analysis were; (i) administrative process, (ii) nutritional value, (iii) variety, (iv) taste-flavor, (v) hygiene and food safety, (vi) intercultural inclusiveness, and (vii) price. NRF 9.3 scores of the campus lunch menu alternatives were low (ranged from 0.09 to 3.19) in a way that triangulated the qualitative findings. Conclusion: This study shows that nutritional value and variety of the food and beverage services is a main driving factor for food selection and participants’ experiences even more than price and taste of the food. The results highlight the importance of serving healthy menus to all the stakeholders of a university, which could best be achieved by employing dietitians.
Surviving and Thriving

Global attention on early child development, inclusive of those with disability, has the potential to translate into improved action for the millions of children with developmental disability living in low- and middle-income countries. Nurturing care is crucial for all children, arguably even more so for children with developmental disability. A high proportion of survivors of neonatal conditions such as prematurity and neonatal encephalopathy are affected by early child developmental disability. The first thousand days of life is a critical period for neuroplasticity and an important window of opportunity for interventions, which maximize developmental potential and other outcomes. Since 2010, our group has been examining predictors, outcomes, and experiences of neonatal encephalopathy in Uganda. The need for an early child intervention program to maximize participation and improve the quality of life for children and families became apparent. In response, the “ABAaNA early intervention program,” (now re-branding as ‘Baby Ubuntu’) a group participatory early intervention program for young children with developmental disability and their families, was developed and piloted. Piloting has provided early evidence of feasibility, acceptability, and impact and a feasibility trial is underway. Future research aims to develop programmatic capacity across diverse settings and evaluate its impact at scale.
Physical activity and sense of coherence: a meta-analysis

ABSTRACT The salutogenic model of health proposes that sense of coherence, a multi-dimensional construct representing individuals’ perceptions that their environment is comprehensible, manageable, and meaningful, is a key determinant of stress management and well-being. Generalized resistance resources such as preventive health orientation, material resources, and social support are proposed as determinants of sense of coherence. Health behaviors, particularly physical activity, are proposed as indicators of a preventive health orientation and predictors of sense of coherence. We synthesized research on the relationship between physical activity and sense of coherence using three-level meta-analysis, and tested effects of key moderators of the relationship. Database and manual searches identified 52 studies meeting inclusion criteria with 73 effect sizes testing the relationship. The analysis revealed a small non-zero physical activity-sense of coherence correlation with significant heterogeneity. Demographic variables, version of sense of coherence scale, physical activity measure, study design and quality, physical activity intensity, and time lag did not moderate the correlation. Findings suggest a robust but small correlation between physical activity participation and sense of coherence across studies. Studies that test the relationship using experimental or intervention designs, adopt more precise measures, and include measures of other health behaviors and generalized resistance resources are needed.
Ocean Acidification and Short‐Term Organic Matter Enrichment Alter Coral Reef Sediment Metabolism Through Different Pathways

Ocean acidification (OA) and organic matter (OM) enrichment (due to coastal eutrophication) could act in concert to shift coral reef carbonate sediments from a present state of net calcification to a future state of net dissolution, but no studies have examined the combined effect of these stressors on sediment metabolism and dissolution. This study used 22‐h incubations in flume aquaria with captive sediment communities to measure the combined effect of elevated pCO2 (representing Ocean Acidification) and particulate organic carbon (representing coastal eutrophication) on coral reef sediment gross primary productivity (GPP), respiration (R), and net calcification (Gnet). Relative to control sediment communities, both OA (pCO2 ~ 1,000 μatm) and OM enrichment (~ +40 μmol C L−1) significantly decreased rates of sediment Gnet by 1.16 and 0.18 mmol CaCO3 m−2 h−1, respectively, but the mechanism behind this decrease differed. The OA‐mediated transition to net dissolution was physiochemical, as rates of GPP and R remained unaffected and dissolution was solely enhanced by a decline in the aragonite saturation state (Ωarg) of the overlying water column and the physical factors governing the pore water exchange rate with this overlying water column. In contrast, the OM‐mediated decline in Gnet was due to a decline in the overlying seawater Ωarg due to the increased respiratory addition of CO2. The decrease in Gnet in response to a combination of both stressors was additive (−0.09 mmol CaCO3 m−2 h−1 relative to OA alone), but this decrease did not significantly differ from the individual effect of either stressor. In this study OA was the primary driver of future carbonate sediment dissolution, but longer‐term experiments with chronic organic matter enrichment are required.
Efficacy of citric acid against Listeria monocytogenes attached to poultry skin during refrigerated storage

Summary The aim of this study was to evaluate the effect of citric acid washing on the growth of Listeria monocytogenes on poultry legs stored at 4 °C for 8 days. Fresh inoculated chicken legs were dipped into either a 0.052, 0.104 or 0.156 m citric acid solution for 5 min or distilled water (control). Surface pH values, sensorial characteristics and L. monocytogenes, mesophiles and psychrotrophs counts were evaluated. Legs washed with 0.156 m citric acid for 5 min showed a significant (P < 0.05) inhibitory effect on L. monocytogenes compared with control legs, being about 1.55 log units lower in the first ones than in control legs after 1 day of storage. Treatments with 0.156 m citric acid reduced bacterial growth and preserved reasonable sensorial quality after storage at 4 °C for 8 days.
Epidemiological profile of candidiasis in HIV/AIDS patients in a tertiary care hospital

In the last decade, a change in the epidemiology of fungal infections has been observed and with an increase in the incidence of fungal infections, mainly due to rising numbers of immunocompromised patients, more advanced treatments and longer hospital stays. Various fungal infections vary from superficial infections to systemic or disseminated disease in HIV/AIDS patients. World health organization (WHO) predictions put India as one of the biggest repository of HIV/AIDS patients in coming decades. ABSTRACT
Computation of madelung energies for ionic crystals of variable stoichiometries and mixed valencies and their application in lithium-ion battery voltage modeling

Electrostatic energy (Madelung energy) is a major constituent of the cohesive energy of ionic crystals. Several physicochemical properties of these materials depend on the response of their electrostatic energies to a variety of applied thermal, electrical, and mechanical stresses. In the present study, a method has been developed based on Ewald’s technique to compute the electrostatic energy arising from ion-ion interactions in ionic crystals such as LixMn2O4 with variable stoichiometries and mixed valencies. An interesting application of this method in computing the voltages of lithium ion batteries employing spinel cathodes is presented for the first time. The effect of including additional interaction terms such as the short-range and the multipolar was estimated and was found to necessitate only a fairly small change in the battery voltage. The advantages of the present method of computation over existing methods are also discussed.
A COMPARISON OF THREE FIELD METHODS FOR MEASURING SATURATED HYDRAULIC CONDUCTIVITY

The saturated hydraulic conductivity, Ks, was measured on a loamy sand, a fine sandy loam, a silt loam and a clay at four 100-m2-area sites in southern Ontario. Twenty measurements of Ks were obtained by each of three different measurement techniques at each of the four sites. The techniques included: (1) the air-entry permeameter method; (2) the constant head well permeameter method using the Guelph Permeameter; and (3) the falling-head permeameter method applied to small soil cores. The Ks data were found to be better described by the log-normal frequency distribution than by the normal frequency distribution. Statistical comparison of the mean Ks values indicated significant differences between some or all of the methods within each site. This site-method interaction was interpreted in terms of the influence of macropores and air entrapment on each of the measurement techniques. The measured Ks values ranged over an order of magnitude on the sand, one to two orders of magnitude on the loams, and three .
Criminal History and Adverse Childhood Experiences in Relation to Recidivism and Social Functioning in Multi-problem Young Adults

This study examines the relationship between criminal history and adverse childhood experiences (ACEs) and how they collectively predict (a) recidivism and (b) positive social functioning among multi-problem young adults. Criminal records and self-report data regarding ACEs and adult education/employment and quality of life (QoL) were collected for 692 multiproblem young adults (18–27 years). Results indicated that an extensive criminal history was related to non-violent and violent recidivism and lack of involvement in education/employment in young adulthood. On the contrary, a higher number of ACEs was related to lower QoL later in life, while this was not associated with recidivism or education/employment. These findings highlight again that past criminal behavior is a strong predictor of future criminality, particularly within this group of young adults with multiple problems. Furthermore, experiencing negative events in childhood shows to have long-term negative effects on QoL even for these individuals who already experience multiple life problems. Implications are discussed.
Taxonomical diversity and palaeobiogeographical affinity of belemnites from the Pliensbachian–Toarcian GSSP (Lusitanian Basin, Portugal)

High‐resolution analysis of the late Pliensbachian – early Toarcian belemnite assemblages from the Peniche section (Lusitanian Basin) has enabled, for the first time, recognition of eight taxa of the suborder Belemnitina, previously reported from contemporaneous north‐west Tethyan and Arctic sections. The presence of Bairstowius amaliae sp. nov. in the late Pliensbachian (emaciatum Zone) represents a novelty given that hitherto the genus Bairstowius was known only from late Sinemurian and early Pliensbachian deposits. Additionally, the replacement of Bairstowius amaliae by Catateuthis longiforma, during the latest Pliensbachian, suggests an evolutionary relationship between the two taxa. This relationship suggests a new scenario for the subsequent development of endemic Toarcian Boreal–Arctic faunas, characterized by the occurrence of Catateuthis. Comparison of the Peniche belemnite fauna with coeval faunas from the Mediterranean/Submediterranean and Euro‐Boreal domains indicates taxonomic uniformity during the late Pliensbachian and early Toarcian (emaciatum and polymorphum Zones), in the north‐west Tethys. Despite the lack of a marked taxonomic turnover, the Pliensbachian–Toarcian boundary corresponds to a slight decrease in diversity observed not only in the Lusitanian Basin but also in coeval north‐western European basins. Ordination and cluster analyses indicate that the largest changes in belemnite diversity and palaeogeographical distribution occurred rather during the Toarcian Oceanic Anoxic Event (base of the levisoni Zone). This event is marked by the extinction of taxa, affecting more severely the Mediterranean/Submediterranean domain and resulting in a more pronounced provincial differentiation among north‐western European and Arctic belemnite faunas.
Shear-Actuation and Vibrometer Reception of Penetrating Ultrasonic Guided Wave Modes in Human Tibia

The hollow long bones of the human appendicular skeleton are known to support the propagation of ultrasonic guided waves, whose potential for diagnosing bone health is being investigated. In this study, ultrasonic guided waves propagating in the diaphysis of human tibia are characterized experimentally and numerically in the frequency range around 200 kHz. The experiment involves a unique combination of omni-directional shear transducer-based excitation and detection using a 1D laser Doppler vibrometer. The cluster of phase velocities obtained from a linear array of time-history data using space-time Fourier transform is found to be in the non-dispersive low-phase velocity region of the dispersion curves obtained for a tibial cross-section. Time-domain finite element analysis revealed that the displacement components normal to the surface are significant, even though the loading is from a shear transducer. Furthermore, semi-analytical finite element analysis revealed that the wave structures of the wave modes contained within the cluster of low-phase velocity modes are consistent with the displacement profiles obtained from the time-domain analysis. The experimental results show that the low-phase velocity mode cluster has sufficient intensity to propagate axially at least 85 mm in the mid-diaphyseal region.
Analysis of Stock Market Returns: Study of Consumer Goods Companies Listed on the Indonesia Stock Exchange

Stocks have the highest risk between other investment instruments, but with the right analysis, the high risk is proportional to the high return that can be obtained. Stock return analysis can be done using a basic approach, namely fundamental analysis and technical analysis. This study aims to examine the effect of the individual stock price index, past stock price, debt to equity ratio (DER), and net profit margin (NPM) in consumer goods industry companies listed on the Indonesia Stock Exchange 2015-2018. This study uses multiple regression analysis models. The population of this study consisted of 60 companies, and the research sample consisted of 27 companies with 108 consumer goods industry companies listed on the Indonesia Stock Exchange 2015-2018 periods. The results showed that individual stock price index, past stock price, DER, and NPM simultaneously have a significant effect on stock return. Partially individual stock price index and past stock prices have a significant effect on stock return. In contrast, DER and NPM have no significant effect on stock return in consumer goods industry companies listed on the Indonesia Stock Exchange in the 2015-2018 periods.
Weighted coordinated motion for coupled harmonic oscillators with heterogeneous interactions of cooperation and competition

ABSTRACT This paper investigates the weighted coordinated motion of coupled harmonic oscillators over weighted cooperative–competitive interactions. First, the traditional synchronisation and containment control concepts are extended to the weighted synchronisation and weighted containment control for the new cooperative–competitive networks. Then, weighted synchronisation problem and weighted containment tracking motion are respectively solved for the coupled harmonic oscillators. Compared with some existing results, the frequency parameters of coupled harmonic oscillators are unknown in this paper and some novel networked structures are introduced in order to make the harmonic oscillator followers converge to the convex hull spanned by leaders' weighted states. Particularly, if the topologies formed by every leader group and follower group are interactively balanced and every follower is weight-product balanced, or if some leader groups are not interactively balanced but satisfy some conditions, the coupled harmonic oscillators can all realise the weighted containment tracking motion. Simulation results are given to demonstrate the effectiveness of the proposed control schemes.
Application of colour combinations on visual search tasks under vibration environments

Abstract Colour is widely utilised as a visual coding system in visual search, but its application under vibration conditions (e.g., in various vehicles) has not been fully explored. This study was designed to examine the effect of colour combinations on performance of visual search tasks conducted in vibration conditions. Forty-eight university students participated in an experiment where they were required to identify target type and location under 24 colour combinations (half in negative polarity and half in positive polarity) and three vibration conditions (static, low, and high). The findings showed that vibration did not significantly affect performance, perceptions, or physiological aspects. Colour combination significantly affected response time, and the participants preferred colour combinations that had the potential to produce better performance. Colour combinations with negative polarity (e.g., yellow on black and white on black) are recommended for presenting search interfaces. These findings are of importance in human–computer interface designs for information display under vibration conditions.
Diagnosis of the Causes of the Rain Flooding in June in the West Africa Coastal Area

Rain flooding during June on the West Africa coastal area is analyzed by using the 95th and 75th percentiles, which represent extreme and intense rainfall events respectively. Thus, the contribution of these events that reaches around 50% shows their impact on the rainfall in June. Atmospheric and oceanic factors influence the rain flooding. Indeed, the extreme events are associated with easterly waves propagating from 20°E, while those of intense events are initiated around 5°E. The impact of oceanic conditions exhibits the warming of the equatorial rail and the Atlantic cold tongue, the warming of the whole ocean basin and a north-south dipole of SST anomalies. The West African monsoon that reaches Abidjan corresponds to a low-level atmospheric flow, whose upward motion extends in latitude from the ocean to the continent. An increase of disturbance contributes to enhancing these events. This is confirmed by the inflow on to the continent of oceanic moisture coming from the ventilation by evaporation of warm water. In addition, the coupled ocean-atmosphere simulations are one of the best candidates that could help to better explain these dramatic events. This study is useful because of showing solutions that could help in adoption of policies for the risks management related to these events.
