Linearity Test

The image obtained in a transmission electron microscope is the two-dimensional projection of a three-dimensional (3D) object. The 3D reconstruction of the object can be calculated from a series of projections by back-projection, but this algorithm assumes that the image is linearly related to a line integral of the object function. However, there are two kinds of contrast in electron microscopy, scattering and phase contrast, of which only the latter is linear with the optical density (OD) in the micrograph. Therefore the OD can be used as a measure of the projection only for thin specimens where phase contrast dominates the image. For thick specimens, where scattering contrast predominates, an exponential absorption law holds, and a logarithm of OD must be used. However, for large thicknesses, the simple exponential law might break down due to multiple and inelastic scattering.

Negative Concept

Gandhiji’s method of conflict resolution was based on truth and non-violence. Truth was for him the image of God. He did not believe in personal God. For Gandhi truth is God and God is truth. Life is a laboratory where experiments are carried on. That is why he named his autobiography “My Experiment with Truth”, without these experiments truth cannot be achieved. According to Gandhi, the sayings of a pure soul which possesses nonviolence, non-stealing, true speech, celibacy and non-possession is truth. The truth of Gandhiji was not confined to any country or community. In other words , his religion had no geographical limits. His patriotism was not different from the service of human beings but was its part and parcel(Mishra:102). Gandhiji developed an integral approach and perspective to the concept of life itself on the basis of experience and experiments. His ideas ,which came to be known to be his philosophy, were a part of his relentless search for truth(Iyer:270). The realization of this truth is possible only with the help of non-violence The negative concept of Ahimsa presupposes the absence of selfishness, jealousy and anger, but the positive conception of ahimsa demands the qualities of love ,liberalism, patience, resistance of injustice, and brutal force.

The Subject

OBJECTIVE: To analyze the impacts of the care to the population displaced by violence on the health system and the challenges that this entails. METHODS: This is a narrative review of the national and international literature in PubMed, SciELO, WHO/PAHO, and Bireme. Inclusion criteria were date of publication ( from 2000), relation with the subject, and language (Spanish or English). We found 292 documents, of which 91 met the inclusion criteria. RESULTS: The main challenges are the intersectoral, participatory, and integral approach (with emphasis on mental health and sexual and reproductive health), ensured accessibility to health services, the need for a reliable registration and information system of the population displaced by violence and its characteristics, and the addressing of the biopsychosocial problems of the different groups, especially women, persons with disabilities or infectious diseases, adolescents, children, ethnic minorities, older adults and the lesbian, gay, bisexual, transsexual, and intersexual population. CONCLUSIONS: The lack of political will to accept and see the internal displacement by violence and its importance as a humanitarian and public health problem is an obstacle to the adequate and timely care of the population displaced by violence in Mexico.

The Coleman integral is a $p$-adic line integral that encapsulates various quantities of number theoretic interest. Building on the work of Harrison [J. Symbolic Comput. 47 (2012) no. 1, 89–101], we extend the Coleman integration algorithms in Balakrishnan et al. [Algorithmic number theory, Lecture Notes in Computer Science 6197 (Springer, 2010) 16–31] and Balakrishnan [ANTS-X: Proceedings of the Tenth Algorithmic Number Theory Symposium, Open Book Series 1 (Mathematical Sciences Publishers, 2013) 41–61] to even-degree models of hyperelliptic curves. We illustrate our methods with numerical examples computed in Sage.
