This scientific article discusses the oral manifestations of diseases of the gastrointestinal tract. This problem is relevant both for dentists and family doctors. In medicine, for a long period of time, the relationship between diseases affecting the gastrointestinal tract and their symptoms manifested in the oral cavity has been considered. Many scientists and physicians have dealt with this problem, their several opinions are presented in this article. There is a hypothesis among researchers that the oral cavity is a mirror in which all human diseases can be visible. In the oral cavity, most of the alterations occurring in the organism are manifested, due to which, with an attentive attitude to oral manifestations, the disease can be detected already at the initial stage.

In this paper, we demonstrate an effective method to compensate the temperature effect of long period fiber grating (LPFG). First it is found that the resonant wavelength of LPFG showes a right shift when the temperature increases while it has an opposite shift when the applied strain increases. On the basis of the characteristic, plexiglass is used to compensate the shift of the resonant wavelength induced by the tempera-ture change. The temperature characteristic of compensated LPFG has been performed. And the compensa-tion experimental result shows the temperature sensitivity of the resonance wavelength of LPFG is reduced from 55.71pm/°C to 3.7pm/°C. It is found that the method to compensate temperature is effective and prac-tical.

This article is based on interviews with fifteen children, whose parents have addiction problems. Purpose: To contribute to in-depth understanding of children's situation when parents have ceased abusing drugs or alcohol. Method: An explorative interview study with childhood sociology and symbolic interactionism as theoretical framework. Outcome: The end of the abuse gives children space to feel how they feel, to reflect on the impact of the addiction on their health and personality, and to try changing themselves and their lives. Their need for processing may last for a long time. It can take time and be difficult to build up the relationship with the parent. Children can still feel care responsibility but also distrust and worry about relapses. However, teenagers can see opportunities to move on with their own life. If the abuse ends only for one of two parents with addiction problems, children are still affected by addiction. Conclusion: Children's need for processing in relation to the parents can both be time consuming and last for a long period of time, regardless of if the child lives with the parent or not. Children may need help for their own part but also in relation to the parent. Professionals should be encouraged to work with a family perspective, regardless of organizational divisions and if parents and children live together or not. This requires structures, procedures and resources for collaboration across organizational boundaries.

AbstractIn the present work we investigate the possible relationship of long-period comets with five large and distant trans-Neptunian bodies (Sedna, Eris, 2007 OR10, 2012 VP113and 2008 ST291) in order to determine the probability of the transfer of a part of these kind of comets to the inner of the Solar System. To identify such relationships, we studied the relative positions of the comet orbits and listed TNOs. Using numerical integration methods, we examined dynamical evolution of the comets and have found one encounter of comet C/1861J1 and Eris.

In this study, emissions of ultrafine particles from a new laser printer were evaluated as a function of toner coverage, number of pages printed, fuser temperature and cartridge rotation during different printing orders. Eight combinations of printing jobs were specifically designed to represent eight printing orders. The toner coverage was found to be an important factor affecting particle emissions from the printer. The printing job without toner coverage (0%) acted as a cleaning process, which would tentatively reduce particle emissions in the next job. Particles generated in printing job with toner coverage (5%) could superimpose onto those emitted from the next job, leading to higher particle number emission in the next job than the previous one. Apart from toner coverage, cartridge rotation was an important factor enhancing particle emissions. Cartridge in rotation mode with/without toner coverage could both cause particle emissions and high fuser temperature. The relationship between the particle emission and the temperature of the fuser unit was very strong ( r2 = 0.96). The regression relationship satisfied a positive power law-rise equation. We also found that ventilation for a long period, printing with no cartridge rotation, and/or printing blank pages before toner page printing could reduce particle emissions.

Whereas in the 1970s early bioethicists believed that bioethics is an arena for the application of philosophical theories of utilitarianism, deontology, and natural law thinking, contemporary policy-oriented bioethicists seem rather to be keen on framing ethical issues through political ideologies. Bioethicists today are often labeled “liberal” or “communitarian,” referring to their different understandings of the relationship between the individual and society. Liberal individualism, with its conceptual base of autonomy, dignity, and privacy, enjoyed a long period of dominance in bioethics, but it has increasingly come under attack from ideologies promoting a more salient role for concepts of solidarity, community, and public interest.

There are quite a few generalizations or applications of the 1984 minimax inequality of Ky Fan compared with his original 1972 minimax inequality. In a certain sense, the relationship between the 1984 inequality and several hundreds of known generalizations of the original 1972 inequality has not been recognized for a long period. Hence, it would be necessary to seek such relationship. In this paper, we give several generalizations of the 1984 inequality and some known applications in order to clarify the close relationship among them. Some new types of minimax inequalities are added.

In this theoretical analysis, we argue that a process referred to as minding is essential for a couple to feel mutually close and satisfied in a close relationship overa long period. Minding represents a package of mutual self-disclosure, other forms of goal-oriented behavior aimed at facilitating the relationship, and attributions about self's and other's motivations, intentions, and effort in the relationship. Self-disclosure and attribution activities in minding are aimed at getting to know the other, trying to understand the other's motivations and deeper dispositions as they pertain to the relationship, and showing respect and acceptance for knowledge gained about other. We link the concept of minding to other major ideas and literatures about how couples achieve closeness: self-disclosure and social penetration, intimacy, empathy and empathic accuracy, and love and self-expansion. We argue that the minding process articulated here has not previously been delineated and that it is a useful composite notion about essential steps in bonding among humans. We also argue that the minding concept stretches our understanding of the interface of attribution and close relationships. We present research possibilities and implications and consider possible alternative positions and counterarguments about the merits of the minding idea for close relationship satisfaction.
