Description:
Nowadays, to be in touch is due to a mobile technology as if it were a matter of course. Mobile networks drop-outs make many people nervous which proves the fact how dependant on networks or on their infrastructure we are. in past twenty years there changed much in the field of interpersonal communication and it is similar in case of small units. Yet the current communication architecture of platoons does not have much in common with commercial mobile networks. Nevertheless, similarly to a civil sphere, even here every soldier must become its part. Question is how to achieve it. The following article deals with issues of small units communication up to 2050, focusing especially on small units deployment in international operations of the NATo countries. and Být stále na příjmu je dnes s ohledem na mobilní technologie takřka samozřejmostí. Případné výpadky mobilních sítí mnohé lidi znervózňují, což jen podtrhuje skutečnost, s jakou samozřejmostí se oddáváme této závislosti na sítích, respektive na jejich infrastruktuře. Za posledních dvacet let se v komunikaci mezi lidmi změnilo mnohé a podobné je to i v případě spojení u malých jednotek. Přesto nemá dnešní komunikační architektura čet s komerčními mobilními sítěmi mnoho společného. Nicméně podobně jako je tomu v civilní sféře, tak i zde musí být její součástí každý voják. Jde jen o to jak a jakým způsobem. Následující článek je věnován problematice komunikace malých jednotek ve výhledu do roku 2050, a to především s ohledem na nasazení malých jednotek v mezinárodních operacích států NATO.

5. Potential solutions to problems posed by the offspring sex ratios of people with parasitic and viral infections

Subject:
cytomegalovirus CMV, Heligmosomoides polygyrus, hepatitis B virus HBV, hepatitis C virus HCV, sex ratio at birth, and Toxoplasma gondii
Language:

Description:
I have hypothesized that mammalian offspring sex ratios (proportions male at birth) are partially controlled by the hormone levels of both parents around the time of conception. Recently data have been published (privately) which impugn suggestions of mine (based on that hypothesis) relating to the offspring sex ratios of people who are carriers of hepatitis B virus; and (publicly) to hormone profiles of women who are infected with the protozoan parasite Toxoplasma gondii. Here these data are reviewed in the light of data on offspring sex ratios of people infected with hepatitis C, and cytomegalovirus and T. gondii; and of mice with T. gondii and the trichostrongyline nematode Heligmosomoides polygyrus. Three proposals are made viz: 1. Women infected with T. gondii may have high oestrogen levels. This would potentially explain reports of their high offspring sex ratios, long gestations and (perhaps) behavioural traits. 2. Some of these infective organisms may 'prefer' a particular endocrine environment in their host (in the sense that it facilitates replication or transmission or both). 3. Some of these organisms apparently cause changes in that endocrine environment as a consequence of their presence. If both the latter two proposals were correct, it could explain recent puzzling data on the offspring sex ratios of hepatitis B carriers. And if this solution turns out to be correct, it would suggest new endocrine means of combating hepatitis B infection.
