The Optimal Number of Charities

In this paper charity brings some joy of giving; it yields more contributions to public goods than standard "subscription", but its creation is costly. We compare the laissez-faire number of charities with both the second and the first-best level. In general, laissez-faire implies an underprovision of both charities and public goods.Charities, Public Good

Intracranial massive subdural haematoma: a potentially serious consequence of diagnostic lumbar puncture

Intracranial subdural haematoma (SDH) is an exceptionally rare complication of lumbar puncture (LP) and cerebrospinal fluid (CSF) drainage. Post LP headache mostly has a benign course, but it can also be a manifestation of a potentially life-threatening complication such as SDH. Only a few cases has been reported in literature. We report a case of massive intracranial SDH in a young male following LP and CSF drainage

Prevalence of thyroid dysfunction in pregnancy and its impact on maternal and fetal outcome: a prospective study in a tertiary care hospital in Maharashtra, India

Background: Thyroid dysfunction is the commonest endocrinological disorder in pregnancy. A broad spectrum of adverse outcomes in pregnant women and the fetus have been reported which can be prevented by early diagnosis and treatment of thyroid dysfunction. Thyroid dysfunction in pregnancy has not yet been extensively studied in India. Hence, this study was conducted for assessment of the prevalence of thyroid dysfunction in pregnancy and effect on the mother and her fetus.Methods: This study is a prospective study conducted in the department of obstetrics and gynecology, MIMER Medical College and Hospital, Talegaon Dabhade, Maharashtra. A 3 years study. Antenatal women attending the outpatient and inpatient department of the hospital. The total sample population comprised of 698 pregnant women with uncomplicated singleton intra-uterine pregnancy. All participants were screened by estimation for serum TSH in first trimester. Immediately after delivery the cord blood sample was collected and cord blood TSH levels were estimated. Babies, whose cord blood TSH levels were elevated, were called for follow-up on day 5 of neonatal life and TSH, free T3 and free T4 levels were estimated. Among these babies, those diagnosed with congenital hypothyroidism were started on appropriate treatment.Results: The prevalence of thyroid dysfunction in pregnancy in present study was 17.90% whereas 82.1% patients were euthyroid (control group). Among the 17.9% patients with thyroid dysfunction, 14.6% had subclinical hypothyroidism, 1.9% had overt hypothyroidism and 1.4% had hyperthyroidism.Conclusions: With this study, we can come to the conclusion that there is high prevalence of thyroid dysfunction in pregnancy. Thus, an early diagnosis and prevention of the aftermaths of thyroid dysfunction in pregnancy is of utmost importance

Observation of insulator-metal transition in EuNiO3_{3} under high pressure

The charge transfer antiferromagnetic (T$_{N}$ =220 K) insulator EuNiO$_{3}$ undergoes, at ambient pressure, a temperature-induced metal insulator MI transition at T$_{MI}$=463 K. We have investigated the effect of pressure (up to p~20 GPa) on the electronic, magnetic and structural properties of EuNiO$_{3}$ using electrical resistance measurements, {151}^Eu nuclear resonance scattering of synchrotron radiation and x-ray diffraction, respectively. With increasing pressure we find at p$_{c}$ =5.8 GPa a transition from the insulating state to a metallic state, while the orthorhombic structure remains unchanged up to 20 GPa. The results are explained in terms of a gradual increase of the electronic bandwidth with increasing pressure, which results in a closing of the charge transfer gap. It is further shown that the pressure-induced metallic state exhibits magnetic order with a lowervalue of T$_{N}$ (T$_{N}$ ~120 K at 9.4 GPa) which disappears between 9.4 and 14.4 GPa.Comment: 10 pages, 3 figure

Specular motion and 3D shape estimation

Dynamic visual information facilitates three-dimensional shape recognition. It is still unclear, however, whether the motion information generated by moving specularities across a surface is congruent to that available from optic flow produced by a matte-textured shape. Whereas the latter is directly linked to the firstorder properties of the shape and its motion relative to the observer, the specular flow, the image flow generated by a specular object, is less sensitive to the object's motion and is tightly related to second-order properties of the shape. We therefore hypothesize that the perceived bumpiness (a perceptual attribute related to curvature magnitude) is more stable to changes in the type of motion in specular objects compared with their matte-textured counterparts. Results from two twointerval forced-choice experiments in which observers judged the perceived bumpiness of perturbed spherelike objects support this idea and provide an additional layer of evidence for the capacity of the visual system to exploit image information for shape inference. © 2017 The Authors

A method to define the priority for maintenance and repair works of Italian motorway tunnels

The construction of motorways in Italy dates back to 1921 and still lasts today. Along them there is a large number of tunnels, many of which have been in service for more than 50 years and have experienced various levels of decay due to aging. An extensive assessment and inspection plan is taking place finalized to highlight situations where maintenance and repair works are needed to guarantee the continuation of service in safe conditions and functionality. Due to the number of tunnels, the need arises to classify them and define priorities for intervention on the basis of a first assessment and of a robust and scientific-based tool to orientate the investments. This paper describes the methodology that was developed by the Authors for this purpose, assessing the attention level of every tunnel. The method relies on a quantitative approach that allows quantifying the risk based on five risk factors composed of a number of relevant parameters. Their relative interaction, which guided the scores assigned to each parameter, was assessed by applying the Rock Engineering System [2]. A number of examples of existing tunnels are shown to illustrate the application of the method and to draw conclusions about its validity and reliability
