The article presents estimates of social minimum baskets for the second and third quarter of 2020, i.e. when the sanitary restrictions resulting from the COVID-19 pandemic took place. They obviously affected the functioning of households in various aspects. The presented estimates take into account the needs as foreseen in the model under normal conditions; the new circumstances of Covid-19 were not taken into account. There is lack of research data on changes in household consumption in 2020. If there will be a need to change assumptions in the model, the values of social minimum can be recalculated in the future. The value of the social minimum in the 2nd quarter increased by 2.1% in a one-person household and by 1.8% in a four -person household, with inflation by 0.3%.The increase in the subsistence minimum was mainly due to a further increase in food prices (from 4.3 to 4.5%), with the costs of housing and energy carriers rising from 1.7 to 2.0%. The very same factor contributed to a decline in the value of the minimum in the third quarter. In this period, the social minimum estimates decreased by -1% in a one-person household and by -1.1% in a four-person household, with a trace increase in CPI index (+0.1%). Seasonal decreases in food prices caused the value of food in the basket to decrease from -6.1 to -6.4%, with a CPI of -2.3% in this expenditure group. This time, expenditure on housing and energy products did not exceed 0.5%

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.
