Objective: To compare the outcome of addition nebulized magnesium sulphate to standard treatment in children with acute severe asthma. Methodology: The trial was undertaken at emergency Paediatrics Department, Federal Government Polyclinic (Post Graduate Medical Institute), Islamabad from 1st April 30th September 2019.Children between 1 12 years age asthma were initially salbutamol thrice and i...

Ring signatures are an important primitive for protecting signers’ privacy while ensuring that a signature in question is indeed issued by some qualified user. This notion can be seen as a generalization of the well-known notion of group signatures. A group signature is a signature such that a verifier can establish its validity but not the identity of the actual signer, who can nevertheless be...

BACKGROUND I designed a percutaneous mastoid vent to provide permanent ventilation to the middle ear. The vent consists of an outer titanium tube that osseointegrates with the mastoid bone and an inner Teflon tube that protrudes into the mastoid antrum. OBJECTIVE To follow up all patients who had the mastoid vent inserted since 1995. STUDY DESIGN AND SETTING Retrospective study of 14 patien...

In EUROCRYPT 2012, Libert, Peters and Yung (LPY) proposed the first scalable revocable group signature (R-GS) scheme in the standard model which achieves constant signing/verification costs and other costs regarding signers are at most logarithmic in N , where N is the maximum number of group members. However, although the LPY R-GS scheme is asymptotically quite efficient, this scheme is not su...

The photochemistry of the stratosphere of Venus was modeled using an updated and expanded chemical scheme, combined with the results of recent observations and laboratory studies. We examined three models, with H2 mixing ratio equal to 2 x 10 3, 5 x 10t, and I x 103, respectively. All models satisfactorily account for the observations of CO, 02, 0 2 CA), and SO2 in the stratosphere, but only th...

We present extremely simple ways of embedding a backdoor in the key generation scheme of RSA. Three of our schemes generate two genuinely random primes p and q of a given size, to obtain their public product n = pq. However they generate private/public exponents pairs (d, e) in such a way that appears very random while allowing the author of the scheme to easily factor n given only the public i...

[1] Atmospheric Infrared Sounder (AIRS) offers a unique opportunity to investigate the variability of mid‐tropospheric CO2 over the entire globe. In this paper, we use AIRS data to examine the interannual variability of CO2 and find significant correlations between AIRS mid‐tropospheric CO2 and large‐scale atmospheric dynamics. During El Niño events, mid‐tropospheric CO2 over the central Pacifi...
