Optical refractive index from ultrasonic velocity in binary liquid mixtures
No full text334-337A new empirical relation connecting the optical refractive
index and the ultrasonic velocity has been tried in the case of solutions
(Durai S & Ramadoss P, Acta Acustica,
89 (2003) 173). In this paper the same is extended to four binary liquid
mixture systems, making use of the experimental data available. The results are
satisfactory. Jacobson’s free length (Lf
) and mean free path () play significant roles. Further Debye temperature a
property of solid like behaviour of liquids is calculated for the systems and
the results are analyzed

Mapping with strings attached: Kite aerial photography of Durai Island, Anambas Islands, Indonesia
No full text<p>A 1:2,000 scale orthophoto map of the southern coast of Durai Island, Indonesia, was created using kite aerial photography and computer vision software. Photographs were taken using a consumer-grade digital camera suspended from the line of a kite that was towed by boat along Durai's coastline. Three hundred and fifty-seven aerial photographs were combined into a mosaic, orthorectified and georeferenced using Agisoft PhotoScan software with ground control points collected via a GPS field survey. The map was created in conjunction with underwater ecological surveys of the coral reefs surrounding the island, and it supports ongoing monitoring and educational outreach efforts. Kite aerial photography provides a low-cost, portable, and technologically straightforward means of collecting large-scale aerial imagery in situations where a conventional, aircraft-based photographic survey is not practical.</p
Misleading imaging features of intracranial dural plasmacytoma: Report of two cases
No full textDurai plasmacytomas are very rare and often disregarded in the differential diagnosis of more common lesions of the convexity. We report two cases. Both patients exhibited headache as a main symptom. Computed tomography and magnetic resonance showed a homogeneously enhanced lesion without calcification and without bone involvement

Changes of soil-rhizosphere microbiota after organic amendment application in a <em>Hordeum vulgare </em>L. short-term greenhouse experiment.
No full textAims In order to counteract the enduring decreases in the quality of agricultural land, mechanistic studies for a more sustainable agricultural crop production were performed. They aimed to assess the effects of organic amendments in combination with mineral fertilizer on soil-rhizosphere microbiota and their influence on soil health and plant performance. Methods In a short-term greenhouse experiment, the effects of pelletized spent mushroom substrate, with different combinations of biochar and mineral fertilizer, on agricultural soil and performance ofHordeum vulgareL were scrutinized. To evaluate improved soil quality, different soil biological and chemical properties, microbial activity, bacterial diversity and plant performance were assessed. Results Plant performance increased across all fertilizer combinations. Bacterial beta-diversity changed from the initial to the final sampling, pointing at a strong influence of plant development on the rhizosphere with increasing abundances ofAcidobacteriaand decreasing abundances ofActinobacteria, Chloroflexi, andBacteroidetes. Microbial activity (FDA), potential enzyme activity and metabolic diversity of the microbial community (BIOLOG) were not affected by the amendments, whereas bacterial community structure changed on family level, indicating functional redundancy. Treatments containing biochar and the highest amount of mineral fertilizer (B_MF140) caused the strongest changes, which were most pronounced for the familiesXanthobacteraceae, Mycobacteriaceae,andHaliangiaceae. Conclusion Applying organic amendments improved plant performance and maintained soil health, contributing to more sustainable crop production. Nevertheless, long-term field studies are recommended to verify the findings of this short-term experiment

The safety and effectiveness of different methods of ear wax removal: a systematic review and economic evaluation
No full textEar wax (cerumen) is a natural secretion produced to protect the inner ear from dirt and other fragments by moving these particles towards the outer ear. If this process does not happen properly, wax may build up causing blockage in the ear canal and the possibility of impaction. People with a build up of ear wax may suffer from hearing loss, discomfort and, on occasions, infection. It may present problems in assessing hearing, blocking the view of the ear drum during medical examination and interfering with the fitting or function of hearing aids. Although it is thought to affect between 2% and 6% of the population in the England and Wales, some groups may be at a higher risk, such as those using hearing aids or with small ear canals and/or skin conditions. Recurrence is thought to be high among some of these groups. The consequences of the build up of ear wax in the ear canal are thought to be a common reason for consultation and cost in general practice with over 2 million consultations per year in the NHS.Methods of removal of ear wax include drops, flushing with water in general practice, and removal with suction or probes in specialist clinics. The relative safety and benefits of these different methods of removal remains uncertain. This research will systematically review published and unpublished evidence on the clinical and cost effectiveness of different methods for the removal of ear wax. Where appropriate, it will develop an economic model using data from this systematic review and other relevant sources to estimate the relative costs and benefits of different methods. In addition, the project will provide recommendations for future research to try to help answer any remaining areas of uncertainty

Postdural puncture headache in paediatric oncology patients
No full textPrevious studies have not determined the correlation between durai puncture and postural headache in paediatric patients. Furthermore, no studies have evaluated the correlation between atypical headache and durai puncture in the paediatric population. Therefore, we prospectively analyzed the incidence of typical postdural puncture headache (PDPHA) and atypical headache in paediatric oncology patients following durai puncture.The study population consisted of 66 paediatric patients undergoing 128 consecutive procedures, including 99 lumbar punctures and 29 bone marrow aspirations without concomitant lumbar puncture. Patients were prospectively randomized into four groups: Group I, preteens (< 13 yr) undergoing lumbar puncture, Group II, adolescents (13–21 yr) undergoing lumbar puncture, Group III, preteens undergoing bone marrow aspiration, and Group IV adolescents undergoing bone marrow aspiration. The presence and description of headache was documented immediately after durai puncture or bone marrow aspiration, and on post-procedure days #1,3 and 5 by personnel blinded to the type of procedure.There was an increase in the incidence of headache (9.1%) after lumbar puncture in patients < 21 yr relative to patients undergoing bone marrow aspiration (P < 0.05). No difference was found between the incidence of typical PDPHA after dural puncture in preteens and adolescents. There was also no difference in the incidence of atypical headache after durai puncture or after bone marrow aspiration among preteens and adolescents.Paediatric patients experience an increased incidence of typical postdural puncture headache after durai puncture compared with age-matched patients undergoing bone marrow aspiration only. Atypical headache is relatively common in the paediatric population after dural puncture or bone marrow aspiration.Les études antérieures n’ont pas établi de corrélation entre la ponction durale et la céphalée posturale chez les patients pédiatriques. En outre, aucune étude de cette population n’a évalué le lien entre la céphalée atypique et la ponction durale. Par conséquent, à la suite d’une ponction durale, nous avons analysé de façon prospective l’incidence d’une céphalée de ponction postdurale (CPPD) typique et atypique chez des patients d’oncologie pédiatrique.La population de l’étude était constituée de 66 patients de pédiatrie subissant 128 examens consécutifs, comprenant 99 ponctions lombaires et 29 ponctions médullaires sans ponction lombaire concomitante. Les patients ont été répartis au hasard en quatre groupes de façon prospective: Groupe I de pré-adolescents (< 13 ans) subissant une ponction lombaire; Groupe II d’adolescents (13–21 ans) subissant une ponction lombaire; Groupe III de pré-adolescents inscrits pour une ponction médullaire et Groupe IV d’adolescents pour une ponction médullaire. La présence de céphalée a été vérifiée et décrite immédiatement après la ponction durale ou la ponction médullaire et 1, 3 et 5 jours suivant les interventions par du personnel qui ignorait le type de technique employé.Il y a eu une incidence accrue de céphalée (9,1 %) à la suite de la ponction lombaire chez les patients < 21 ans par rapport aux patients qui ont subi une ponction médullaire (P < 0,05). Aucune différence n’est apparue dans l’incidence de CPPD typique après une ponction lombaire chez les pré-adolescents et chez les adolescents. Il n’y avait pas non plus de différence dans l’incidence de céphalée atypique après une ponction durale ou une ponction médullaire parmi les pré-adolescents et les adolescents.Les patients de pédiatrie ont connu une incidence accrue de céphalée de ponction postdurale à la suite d’une ponction durale quand on les compare aux patients du même âge qui ont subi une ponction médullaire seulement. La céphalée atypique est relativement fréquente dans la population pédiatrique après une ponction durale ou une ponction médullaire
