Methods Single center, retrospective, observational study in an 8-bed adult general ICU (January 2011-June 2014). Patients ≥75 years were divided into two age-groups, 75-84 and ≥85 years old. Characteristics on ICU admission were recorded. Patients hospitalized ≤48 hours were excluded. ICU, hospital, 6-months and 1-year after hospital discharge mortality were calculated. Univariate analysis for...

The volume of crevicular fluid is directly proportional to the degree ofperiodontal inflammation. The Periopaper system, with readings taken using the Periotron, has gained wide acceptance in the literature for measuring this volume. Alternative methods have also been proposed. This study investigated an alternative device for measuring the volume and compared it to the readings taken in Periot...

It has been shown that large gains in speech intelligibility can be obtained by using the binary mask approach which retains the time-frequency (T-F) units of the mixture signal that are stronger than the interfering noise (masker) (i.e., SNR>0 dB), and removes the T-F units where the interfering noise dominates. In this paper, we introduce a new binary mask for improving speech intelligibility...

medication errors (mes) are the most common error in icus. in fact, 78% of all serious errors in icus are due to mes. therefore, detecting mes has vital significance. the goal of this study was to investigate the frequency, type and consequences of different types of errors including prescribing, transcribing and administration errors in an icu of a large teaching hospital. disguised direct obs...

Due to the special (procedural) nature of the language (verbal communication) ‘knowledge’, the dominant trends in applied linguistics research in the last few decades have been advocating ‘acquisition’ rather than ‘learning’ activities where the main focus in SL & FL education should be on ‘meaning’ while some ‘focus-on-form’ being justified. But the ‘form’ to be ‘focused-on’ is mostly misconce...

Transfusion-associated graft-versus-host disease can be prevented by treating cellular blood products with gamma irradiation. A wide range of gamma irradiation dose levels has been used in routine practice. We used limiting dilution analysis, which measures clonable T cells, to assess the influence of 500 to 3,000 cGy of gamma irradiation delivered from a 137Cs source on T cells when delivered ...

The paper considers fault diagnosis in a large system comprising a collection of small subsystems or units which can test one another for the existence of a faulty condition. If subsystem a is not faulty and tests subsystem 8, a correct indication of the status of j.3 is obtaiued; if a is faulty, the test outcome contains meaningless information. A particular form of interconnection is examined...

Methods to measure T antigen-forming capacities of simian virus 40 (SV40) and adenovirus 12 (Ad12) were investigated, and a method to measure the capacity in terms of T antigen-forming units was employed by the use of cytosine arabinoside. Plaque-forming units and T antigen-forming units of SV40, SV40 deoxyribonucleic acid, or Ad12 were inactivated by ultraviolet (UV) irradiation at the same ra...

Methods to measure T antigen-forming capacities of simian virus 40 (SV40) and adenovirus 12 (Adl2) were investigated, and a method to measure the capacity in terms of T antigen-forming units was employed by the use of cytosine arabinoside. Plaque-forming units and T antigen-forming units of SV40, SV40 deoxyribonucleic acid, or Adl2 were inactivated by ultraviolet (UV) irradiation at the same ra...
