SMARANDACHE SEMIRINGS AND SEMIFIELDS
No full textIn this paper we study the notion of Smarandache semirings and semifields and obtain some interesting results about them. We show that not every semiring is a Smarandache semiring. We similarly prove that not every semifield is a
Smarandache semifield. We give several examples to make the concept lucid. Further, we propose an open problem about the existence of Smarandache semiring S of finite order
Smarandache Non-Associative (SNA-) rings
No full textIn this paper we introduce the concept of Smarandache non-associative rings,
which we shortly denote as SNA-rings as derived from the general definition of a
Smarandache Structure (i.e., a set A embedded with a week structure W such that a proper subset B in A is embedded with a stronger structure S
Parastrophic invariance of Smarandache quasigroups
No full textThe study of the Smarandache concept in groupoids was initiated by W.B. Vasantha Kandasamy in [18]. In her book and first paper on Smarandache concept in loops, she defined a Smarandache loop as a loop with at least a subloop which forms a subgroup under the binary operation of the loop

In her book and first paper on Smarandache concept in loops, she defined a Smarandache loop (S ¡ loop) as a loop with at least a subloop which forms a subgroup under the binary operation of the loop
SMARANDACHE NEAR-RINGS AND THEIR GENERALIZATIONS
No full textIn this paper we study the Smarandache semi-near-ring and nearring, homomorphism, also the Anti-Smarandache semi-near-ring. We obtain
some interesting results about them, give many examples, and pose some
problems. We also define Smarandache semi-near-ring homomorphism

The Correlation Of Optic Neural Sheath Diameter With Severity And Mortality In Patients With Non-Traumatic Intracranial Haemorrhage
No full textPurpose:To study the optic neural sheath diameter in non-traumatic intracranial hemorrhage patient in order to identify if this bedside non-invasive ultrasonographic investigation may provide some guidance to subsequent clinical decisions. We evaluated the correlation between Optic neural sheath Diameter (ONSD), haemorrhage volume, Glasgow Coma Scale, and Intracerebral haemorrhage Score (ICH score).Materials and Method:This was a prospective single center, single operator, observational study carried out for 6 months from September 2017 till February 2018. Total of 50 patients were approached, out of which 5 were excluded due to ineligibility. ONSD was measured using standard technique as described in literature. The data was analysed using SPSS 24. Correlation between ONSD-haemorrhage volume, ONSD-GCS and ONSD-ICH Score were assessed using Pearson correlation.Results:The study included 45 patients (mean age: 59.9 +/- 13.4 years old, 26(57.8%) Male), with the mean ONSD value 0.5919 +/- 0.046 cm. The statistical assessment yielded positive correlation value of 0.303 (p-value = 0.043) between ONSD-Haemorrhage volume and correlation between ONSD-ICH was 0.372 (p-value = 0.012). Moreover, a negative correlation value of - 0.351 (p-value = 0.018) were shown between ONSD-GCS.Conclusion:Our study, indicate that as haemorrhage volume increases the ONSD increases as well. This correlation is similarly seen with increases in ICH score suggesting increase in mortality risk. ONSD is a non-invasive method to evaluate severity and mortality risk in patients with non traumatic intracranial haemorrhage
Eye Tracking as a Behavioural Measure of Impulsivity
No full textComputerized testing provides insight into behaviours difficult to measure in traditional paper-pencil testing, such as impulsivity. Eye-tracking was recorded during the Peabody Picture Vocabulary Test, Fourth Edition digital stimulus book administration and output (saccadic speed, pupillary dilation, fixation duration, and reaction time) was used to predict impulsivity, as measured by the Barratt Impulsiveness Scale - Eleventh Edition. Demographic factors including ADHD diagnosis, age, gender, handedness, and SES were considered. Participants were 64 undergraduate students (50 women) at a medium-sized, ethnically diverse, university in southwestern Ontario. Hierarchical regressions showed greater impulsivity predicted lower PPVT-IV Standard Scores. Slower reaction-time and smaller pupil dilation predicted greater impulsivity, consistent with previous research. Impulsivity was related to ADHD diagnosis and gender, while PPVT-IV scores were associated with age and household income. Findings lend insight into the disparity between self-report and behavioural measures of impulsivity and provide objective measures to supplement behavioural observations during testing
ON SMARANDACHE RINGS
No full textIt is proved that a ring R in which for every x ∈ R there exists a (and hence
the smallest) natural number n(x) > 1 such that xn(x) = x is always a Smarandache
Ring. Two examples are provided for justification
Smarandache rings
No full textOver the past 25 years, I have been immersed in research in Algebra and more particularly in ring theory. I embarked on writing this book on Smarandache rings (Srings) specially to motivate both ring theorists and Smarandache algebraists to develop and study several important and innovative properties about S-rings
