Screening of Selected Herbicides for Weed Control in Maize Zea Mays L

An experiment was conducted at Imo State University Teaching and Research farm between April and July 2008 to study the efficacy of selected herbicides in controlling weeds in maize ( Zea mays L. ).The experiment consisted of recommended rates of primextra (T1), Ultrazine (T2) fusillade forte (T3) a weedfree plot (T4) and weedy check (T5) treatments, giving a total of five treatments. The experiment  was laid our in a completely randomized design (CRD) in three replicates. Primextra and ultrazine herbicide treatments significantly reduced the mean weed population and increased the vegetative and yield attributes of maize than that of the unweeded plot treatment.

Older people's experiences of their kitchens: 2000 to 2010

Purpose – This paper aims to present the quantitative results based on a comparison and evaluation of older people's experiences, needs and wants from their current kitchens, combining and comparing the results obtained from two studies conducted in 2000 and 2010 to see what progress has been made. Design/methodology/approach – A study in 2010 investigated the life-long and contemporary experiences of kitchens of 48 people aged over 60 years of age. The research included detailed questionnaire interviews asking people about their experiences of living in their current kitchen. A previous study, conducted in 2000, asked many of the same questions of 22 people in the same age group. Findings – By combining and comparing the two sets of data it seems that only limited progress has been made in terms of kitchen design meeting the needs of older people between 2000 and 2010. Research limitations/implications – Owing to the small sizes of the samples it is not possible to compare the figures statistically or present them as fully representative of the British older population but while the two samples are limited both had similar characteristics of age and gender, so differences do show potential trends over time. Practical implications – The research refers to guidance and a computer based design tool and identifies a number of practical implications for design. Social implications – As people age their abilities and needs can change and their kitchen may no longer be as accessible or appropriate to their needs. Originality/value – This paper adds to the relevant guidance for designers, developers and managers of buildings where the continued personal use of a kitchen is important for continuing independence of older people

Impact of brewery wastewater sludge on microbiological quality of agricultural soil

Impact of brewery wastewater sludge on microbiological quality of agricultural soil was studied using standard methods. Different concentrations of brewery wastewater sludge were added to soil sample collected from abandoned farm land to produce test soil samples A to C; and a control (without sludge). The samples were allowed to stay for 80 days with exposure to same environmental condition. Standard methods were deployed to isolate and group organisms from the soil samples. Important microbes such as Streptococcus sp., Klebsilla sp., Proteus sp., Vibrio sp., Shigella sp., Micrococcus sp., Pseudomonas sp., Enterobacter sp., Escherichia sp., and Bacillus sp amongst others were isolated. The isolated organisms and their loads were more on the test soil samples against the control. These could be indication of the impact of the brewery sludge on the soil. Organisms isolated and grouped have one or more beneficial role to play with relevance to agricultural soil. This study has revealed the impact of brewery wastewater sludge on microbiological quality of agricultural soil

Morbidity and mortality amongst infants of diabetic mothers admitted into a special care baby unit in Port Harcourt, Nigeria

<p>Abstract</p> <p>Background</p> <p>Infants born to diabetic women have certain distinctive characteristics, including large size and high morbidity risks. The neonatal mortality rate is over five times that of infants of non diabetic mothers and is higher at all gestational ages and birth weight for gestational age (GA) categories.</p> <p>The study aimed to determine morbidity and mortality pattern amongst infants of diabetic mothers (IDMS) admitted into the Special Care Baby Unit of University of Port Harcourt Teaching Hospital.</p> <p>Methods</p> <p>This was a study of prevalence of morbidity and mortality among IDMs carried out prospectively over a two year period. All IDMs (pregestational and gestational) admitted into the Unit within the period were recruited into the study.</p> <p>Data on delivery mode, GA, birth weight, other associated morbidities, investigation results, treatment, duration of hospital stay and outcome were collated and compared with those of infants of non diabetic mothers matched for GA and birth weight admitted within the same period. Maternal data were reviewed retrospectively. Data were analyzed using SPSS 16.0.</p> <p>Results</p> <p>Sixty percent of the IDMs were born to mothers with gestational diabetes, while 40% were born to mothers with pregestational DM. 38 (74.3%) were born by Caesarian section (CS), of which 20 (52.6%) were by emergency CS. There was no significant difference in emergency CS rates, when compared with controls, but non-IDMs were more likely to be delivered vaginally. The mean GA of IDMs was 37.84 weeks ± 1.88. 29 (61.7%) of them were macrosomic. The commonest morbidities were Hypoglycemia (significantly higher in IDMs than non-IDMs) and hyperbilirubinaemia in 30 (63.8%) and 26 (57.4%) respectively.</p> <p>There was no difference in morbidity pattern between infants of pre- gestational and gestational diabetic mothers. Mortality rate was not significantly higher in IDMs</p> <p>Conclusions</p> <p>The incidence of macrosomia in IDMs was high but high rates of emergency CS was not peculiar to them. Hypoglycaemia and hyperbilirubinaemia were the commonest morbidities in IDMs.</p> <p>Referring women with unstable metabolic control to specialized centers improves pre- and post- natal outcomes. Maternal-Infant centers for management of diabetes in pregnancy are advocated on a national scale to reduce associated morbidity and mortality</p

Biodiversity defrosted : unveiling non-compliant fish trade in ethnic food stores

Out of nearly 30,000 teleosts dwelling in our planet’s water bodies, only hundreds of them are commercially exploited and prevail on the global food market. Yet, our estimates of the species actually underpinning global trade is severely hampered by inaccuracy and non-compliance in labelling and reporting. Here, we target ethnic food stores in two British cities (Liverpool and Manchester metropolitan areas), whose numbers are increasing throughout Europe, to examine accuracy of traceability information available to consumers. Despite the existence of thorough EU labelling regulations, we unveil a high level of non-compliance, with a diverse range of poorly-known fish species, often sold without any label, or with erroneous information, as demonstrated by DNA barcoding. Results indicate that about 41% of the samples were mislabelled, in stark contrast with a recent study that, in 2015, found less than 5% mislabelling in EU supermarkets and fishmongers. These results highlight that inspectors and governments might not be fully aware of the wide diversity of fish species traded, indicating the need for a stronger enforcement of the EU labelling legislations. Compliance with regulations is required not only to protect consumers, but also fish stocks, as for many of the species identified in this survey, population assessment is poor or lacking altogether

J Charles Henry1, James H Peace2, Jeanette A Stewart3,4, William C Stewart3,41Little Rock Eye Clinic, Little Rock, AR, USA; 2Diabetic Eye Medical Clinic, Inglewood, CA, USA; 3PRN Pharmaceutical Research Network, LLC, Dallas,TX, USA; 4Carolina Eye Institute, University of South Carolina, School of Medicine, Columbia, SC, USAPurpose: To evaluate the efficacy, safety and tolerability of changing to travoprost BAK-free from prior prostaglandin therapy in patients with primary open-angle glaucoma or ocular hypertension.Design: Prospective, multi-center, historical control study.Methods: Patients treated with latanoprost or bimatoprost who needed alternative therapy due to tolerability issues were enrolled. Patients were surveyed using the Ocular Surface Disease Index (OSDI) to evaluate OSD symptoms prior to changing to travoprost BAK-free dosed once every evening. Patients were re-evaluated 3 months later.Results: In 691 patients, travoprost BAK-free demonstrated improved mean OSDI scores compared to either latanoprost or bimatoprost (p&amp;nbsp;&amp;lt; 0.0001). Patients having any baseline OSD symptoms (n = 235) demonstrated significant improvement after switching to travoprost BAK-free (p&amp;nbsp;&amp;lt; 0.0001). In 70.2% of these patients, symptoms were reduced in severity by at least 1 level. After changing medications to travoprost BAK-free, mean intraocular pressure (IOP) was significantly decreased (p &amp;lt;&amp;nbsp;0.0001). Overall, 72.4% preferred travoprost BAK-free (p &amp;lt; 0.0001, travoprost BAK-free vs prior therapy). Travoprost BAK-free demonstrated less conjunctival hyperemia than either prior therapy (p &amp;lt;&amp;nbsp;0.0001).Conclusions: Patients previously treated with a BAK-preserved prostaglandin analog who are changed to travoprost BAK-free have clinically and statistically significant improvement in their OSD symptoms, decreased hyperemia, and equal or better IOP control.Keywords: glaucoma, prostaglandin analog, travoprost, latanoprost, bimatoprost, preservative, benzalkonium chloride, ocular surface diseas

Biodegradation of Crude Oil Polluted Soil by Co-Composting with Agricultural Wastes and Inorganic Fertilizer

Pollution of the environment by petroleum products is inevitable due to oil production,   transportation and distribution activities.   The present study is aimed at examining the extent of bioremediation that can be achieved in crude oil polluted soil after supplementing with organic manure (poultry droppings and goat dung); inorganic fertilizer (NPK 15:15:15) and saw dust respectively. A bioremediation study was carried out on soil experimentally polluted with Bonny Light crude oil by supplementation with organic and inorganic nutrients (poultry manure, goat dung, saw dust and NPK fertilizer). The efficacy of the treatments was monitored for 112days by the measurement of total hydrocarbon utilizing bacteria load and some physico-chemical parameters. The polluted soil (Control) sample had mean bacterial counts of 8.8x104, 9.0x104, 9.2´104, 9.9x104 and 7.6x104 cfu/g respectively. Sample treated with NPK fertilizer had mean bacterial counts of 4.4x104, 4.6x104, 4.7x104, 4.9x104 and 5.2x104 cfu/g on days 0,28,56,84 and 112 respectively; sample treated with poultry manure had mean bacterial counts of 1.6x104, 1.8x104, 2.0x104, 2.4x104 and 2.7x104 cfu/g on days 0, 28,56,84 and 112 respectively; the saw dust treated sample had mean bacterial counts of 2.0x104, 2.3x104, 2.7x104, 2.9x104 and 3.0x104 cfu/g on days 0,28,56,84 and 112 respectively while that treated with goat dung had mean bacterial counts of 9.3x104, 9.5x104, 9.6x104, 9.8x104and 9.9x104 cfu/g on days 0,28,56,84 and 112 respectively.  There were differences in the physico-chemical analyses from the diverse samples. After statistical analysis (P£0.05) there was a significant difference between the different treated samples from the control. The results suggest that nutrient supplementation would be effective in the remediation of crude oil polluted soils. The potentials of various treatment options for the bioremediation of crude oil polluted soils seems to hold the most immediate solution especially for use in areas that would be adversely affected by physical or other removal methods. In this study, the reduction of oil in the treated samples is evident, polluted samples supplemented with fertilizer and poultry manure respectively proved to be the best options during the 112 days study period. This study shows that those organic supplements containing nitrogen and phosphorus have great potentials for the remediation of soils contaminated with petroleum hydrocarbon within a reasonable time.

Automated inspection of turbine blades: Challenges and opportunities

Current inspection methods for complex shapes and contours exemplified by aircraft engine turbine blades are expensive, time-consuming and labor intensive. The logistics support of new manufacturing paradigms such as integrated product-process development (IPPD) for current and future engine technology development necessitates high speed, automated inspection of forged and cast jet engine blades, combined with a capability of retaining and retrieving metrology data for process improvements upstream (designer-level) and downstream (end-user facilities) at commercial and military installations. The paper presents the opportunities emerging from a feasibility study conducted using 3-D holographic laser radar in blade inspection. Requisite developments in computing technologies for systems integration of blade inspection in production are also discussed
