Abstract:
the de rebus bellicis is a small text of petition addressed by an unknown author to a late antique emperor. it contains a list of proposals for economic, political and military reforms with the purpose of improving the roman empire's de fensive capacity in front of the barbarian invaders. contemporary historiography has valued these reform projects variously and in some cases even expressed opposing views. equally different are the interpretations made of the author on ground of the text. the present article, after briefly reviewing the text and structure of the treatise, compares it with other written material of its time with the purpose of placing it in context. this analysis proves the de rebus bellicis to be a typical product of its own time. finally, a new interpretation of two doubtful fragments shows that modern evaluations of the text and its author have not always been solidly founded.

Abstract:
Is it still possible to distinguish the line that separates the country and the city? How do rural and urban workers produce their life today? What are the characteristics that distinguish or approximate them? What movements of resistance have been observed? These questions guide our reflections about the relationship between urban and rural space. Based on a study in the urban pe-riphery and in encampments and settlements of the Landless Rural Workers Movements in Brazil, we seek to understand alternative forms of occupation of space today.

Abstract:
objective: to report the long-term (30-month) effect of the switch from insulin to sulfonylurea in a patient carrying the p.g53d (c.158g>a) mutation in kcnj11 gene. subject and method: a 29-year-old male patient was diagnosed with diabetes in the third month of life and after identification of a heterozygous p.g53d mutation in the kcnj11 gene, the therapy was switched from insulin to sulfonylurea. results: long-term follow-up (30 months) showed that good metabolic control was maintained (hba1c: 6.6%) and the glibenclamide dose could be reduced. conclusion: long-term therapy with sulfonylureas in patients with neonatal diabetes due to mutation in the kcnj11 gene is safe and promotes sustained improvement of glycemic control.

Abstract:
In this paper, we will derive the following formula for the value of the gravitational constant G: (1). This equation has only 0.81% error compared to the common accepted value [1]. The parameters in the equation are the following: the fine structure constant, qthe elementary charge, the mass of the electron, the permittivity of the free space, ethe exponential function and the relation between a circumference and its diameter. Values attached:[2],

Abstract:
The fine-structure constant α [1] is a constant in physics that plays a fundamental role in the electromagnetic interaction. It is a dimensionless constant, defined as: (1)
being q the elementary charge, ε0 the vacuum permittivity, h the Planck constant and c the speed of light in vacuum. The value shown in (1) is according CODATA 2014 [2].
In this paper, it will be explained that the fine-structure constant is one of the roots of the following equation: (2)
being e the mathematical constant e (the base of the natural logarithm). One of the solutions of this equation is: (3)
This means that it is equal to the CODATA value in nine decimal digits (or the seven most significant ones if you prefer). And therefore, the difference between both values is: (4)
This coincidence is higher in orders of magnitude than the commonly accepted necessary to validate a theory towards experimentation.
As the cosine function is periodical, the Equation (2) has infinite roots and could seem the coincidence is just by chance. But as it will be shown in the paper, the separation among the different solutions is sufficiently high to disregard this possibility.
It will also be shown that another elegant way to show Equation (2) is the following (being i the imaginary unit): (5)
having of course the same root (3). The possible meaning of this other representation (5) will be explained.

In the history of mathematics
different methods have been used to detect if a number is prime or not. In this
paper a new one will be shown. It will be demonstrated that if the following
equation is zero for a certain number p,
this number p would be prime. And
being m an integer number higher than (the lowest, the most efficient the operation). . If the result is an integer, this result will tell
us how many permutations of two divisors, the input number has. As you can
check, no recurrent division by odd or prime numbers is done, to check if the
number is prime or has divisors. To get to this point, we will do the
following. First, we will create a domain with all the composite numbers. This
is easy, as you can just multiply one by one all the integers (greater or equal
than 2) in that domain. So, you will get all the composite numbers (not getting
any prime) in that domain. Then, we will use the Fourier transform to change
from this original domain (called discrete time domain in this regards) to the
frequency domain. There, we can check, using Parseval’s theorem, if a certain
number is there or not. The use of Parseval’s theorem leads to the above
integral. If the number p that we
want to check is not in the domain, the result of the integral is zero and the
number is a prime. If instead, the result is an integer, this integer will tell
us how many permutations of two divisors the number p has. And, in consequence information how many factors, the number p has. So, for any number p lower than 2m？- 1, you can check if it is prime or not, just making the
numerical definite integration. We will apply this integral in a computer
program to check the efficiency of the operation. We will check, if no further
developments are done, the numerical integration is inefficient computing-wise
compared with brute-force checking. To be added, is the question regarding the
level of accuracy needed (number of decimals and number of steps in the
numerical integration) to have a reliable result for large numbers. This will
be commented on the paper, but a separate study will be needed to have detailed
conclusions. Of course,

Abstract:
wolfram syndrome (ws) is an autosomal recessive progressive neurodegenerative disorder characterized by diabetes mellitus and optic atrophy. diabetes insipidus and sensorineural deafness are also noted frequently, explaining the acronym didmoad (diabetes insipidus, diabetes mellitus, optic atrophy and deafness) by which the syndrome is also referred. additional manifestations such as atonic bladder, ataxia, nystagmus and predisposition for psychiatric illness may be present. the wolfram syndrome gene, wfs1, was mapped to chromosome 4p16.1 by positional cloning. it encodes an 890-amino-acid polypeptide named wolframin. although the wolframin function is still not completely known, its localization to the endoplasmic reticulum suggests it can play a role in calcium homeostasis, membrane trafficking and protein processing. knowing the cellular function of wolframin is necessary for understanding the pathophysiology of wolfram syndrome. this knowledge may lead to development of therapies to prevent or reduce the outcomes of ws.

Abstract:
While the routine use of Leontief’s closed model is limited to the case
in which the whole income of an economy goes to wages, this paper shows that
the model also permits the representation of production programs corresponding
to every level of income distribution between wages and profits. In addition,
for each of these programs, the model allows calculating the price system and
the profit rate when this rate is the same in all industries. Thus, the results
obtained in Sraffa’s surplus economy are established following an alternative
way, this makes it possible to build a particular standard system for each
level of income distribution between wages and profits. Besides, the fact that
the model includes the set of households as a particular industrial branch permits
to build a balanced-growth path of the economy in which the quantities of work
used in each industry as well as the goods consumed by the workers are studied
explicitly, unlike what happens in von Neumann’s model. The paper also shows
that, under a weak assumption, the balanced-growth rate is independent of the
worker’s choice.

This paper studies, within a growth model, some effects of the inequality between the profit and growth rates on the reproduction of economic elites. To this end, it considers as functions of the capital/income ratio the relations between, on the one hand, the economic growth rate and, on the other hand, the growth rates of capital and of national income. Based on this, it shows that when the income of a particular socio-economic stratum increases with respect to the national income, the lower limit for the growth rate of the first income depends almost exclusively on the variations of the capital/income ratio and of the average productivity of labor, while the employment growth rate plays a secondary role. Moreover, the paper distinguishes between three categories of renter and establishes sufficient conditions for the reproduction of each one of them. It points out that the third category, which comprises those renter dynasties whose share in the national capital stock increases with each generation, constitutes a quasi-feudal development within capitalist societies.
