A survey has been made of the structure of the wood of Eucalyptusgigantea Hook. f. in relation to growing conditions in the Australian CapitalTerritory. Using the number of cells cut off by the cambium at various intervalsduring the growing season as a measure of growth, mathematical expressionshave been obtained for growth in young trees at ground level, breast height,.and half height; from these, growth rate curves have been derived. The timeof year at which growth commences, the relationship of vessel production tocommencement of growth, the formation of late wood, and the period of dormancyhave all been considered in detail. Variations in fibre dimensions havebeen investigated in relation to growth and it has been shown that in anyonegrowth ring the shortest fibres are found in the early wood and the longest inthe late wood. An intrinsic relationship between growth rate and fibre dimensions�has been established, and, at the junction between late and early wood, asudden change in fibre dimensions occurs corresponding to the discontinuity ingrowth rates. Anomalous woody tissue formed during severe drought conditionsis also described.

‘Archive’ is a totality of records, layers and memories that are collected. A city is the archive that consists of the conscious selection of these layers and traces of the past and the present, looking towards the future. Metaxourgio is an area in the wider historic urban area of Keramikos in Athens that includes traces of various eras, beginning in the Antiquity and continuing all the way into the 21st century. Its archaeological space ‘Demosion Sema’ is mostly concealed under the ground level, waiting to be revealed. In this proposal, Metaxourgio is redesigned in light of archiving. Significant traces of the Antiquity, other ruins and buildings are studied, selected and incorporated in the new interventions. The area becomes the ‘open archive’ that leads towards its lost identity. The proposal aims not only to intensify the relationship of architecture with archaeology, but also to imbue the area’s identity with meanings that refer to the past, present and future.

ObjectiveTo test the hypothesis that acute ischemic patients with poorer collaterals would have faster ischemic core growth, we included 2 cohorts in the study, cohort 1 of 342 patients for derivation and cohort 2 of 414 patients for validation purpose.MethodsAcute ischemic stroke patients with large vessel occlusion were included. Core growth rate was calculated by the following equation: Core growth rate = Acute core volume on CTP/Time from stroke onset to CTP. Collateral status was assessed by the ratio of severe hypoperfusion volume within the hypoperfusion region of CTP. The CTP collateral index was categorized in tertiles; for each tertile, core growth rate was summarized as median and inter-quartile range. Simple linear regressions were then performed to measure the predictive power of CTP collateral index in core growth rate.ResultsFor patients allocated to good collateral on CT perfusion (tertile 1 of collateral index), moderate collateral (tertile 2), and poor collateral (tertile 3), the median core growth rate was 2.93 mL/h (1.10–7.94), 8.65 mL/h (4.53–18.13), and 25.41 mL/h (12.83–45.07) respectively. Increments in the collateral index by 1% resulted in an increase of core growth by 0.57 mL/h (coefficient = 0.57, 95% confidence interval = [0.46, 0.68], p < 0.001). The relationship of core growth and CTP collateral index was validated in cohort 2. An increment in collateral index by 1% resulted in an increase of core growth by 0.59 mL/h (coefficient = 0.59 [0.48–0.71], p < 0.001) in cohort 2.ConclusionCollateral status is a major determinant of ischemic core growth.

The relationship between cortical area and fibre area has been examined in the N/N, N/ +, + / +, + /nr and nr/nr genotypes of the New Zealand Romney, using skin biopsies taken at birth, 1, 3 and 16 months of age. The presence of the nr gene was shown to reduce significantly the relative cortical area. Within the genotypes there was an increase in relative cortical area with increasing age and in two-tooth ewes of N/N and N/ + there was an increase in relative cortical area in winter compared to summer.Fibre growth rates in length for primaries and for prenatal and post-natal secondaries were found for lambs between 1 and 3 months and for 16-monthold ewes. In N/N, N/+ and nr/nr primary fibre growth tended to be increased and post-natal secondary fibre growth tended to be decreased relative to + / + values.In both cortical area and fibre growth rate the greatest genotypic effect was shown by the primary fibres.Some estimates of cortical volume have been made by combining the information on cortical area and fibre growth rate and the relationship of these factors to follicle density and mean fibre area has been discussed. Finally, an indication has been given of how the associations of all these four factors might be usefully examined in some British breeds.

Observations are reported on factors affecting the ratio of secondary to primary follicles (SJP) in a flock of Merino sheep.It was found that all follicles were initiated prior to birth but that the number which finally came to maturity (production of fibre) was significantly affected by birth weight and growth from birth to 1 month. Growth at later ages appeared to be unimportant. There was a significant correlation (r = +0.29) between birth weight and log potential S/P at birth. This is interpreted to indicate that while pre-natal growth conditions affect the number of follicles initiated, other factors are also of considerable importance. It is concluded that the larger animals at birth also have a greater total number of primary follicles than smaller animals. It is further concluded that this difference in total primary follicles results primarily from differences in size a t the 90th day of pre-natal life rather than from differences in density a t that time.

The article deals with gnosis and features of metacognition. Initially, the Gnostics considered whether the term "gnosis" was used, what knowledge did they gain from certain experiences. The subject matter of the study reveals important features of the human psyche. For example, the property of separating one’s self from the external environment is like seeing oneself from the side. This property empowers a person in communicating with other people. This expanded opportunity purifies the human being, because it leads to self-control. During vegetable growing, conditions of a special nature can be experienced by themselves. The Gnostics also spoke about it.The article states that the philosophy of gnosis operates through belief in the special inner world of man, the higher world. But this higher can only be felt when a person is in a state of enstasis as a compensatory trance.The article compares the gnosis of the ancient world with modern philosophical trends. Here, in the descriptions of the inner world of man, the divine transcendence is demonstrated. In this regard, the Gnostics sought knowledge of the true state of mind. This search is engaged in metacognition.The author of the article considers it necessary to clarify what metacognition is. A person has the ability to understand what he or she is thinking. Scientists call it metacognition. Metacognition is when a person feels the world not through the prism of his thoughts, but directly. We can also see this in Gnostics with deep compensatory enstasis, or compensatory trance. Then the person stands apart, because it breaks all the wrong connections. Gnosis tries to capture the knowledge of all these processes. Metacognition helps to establish certain characteristics of compensatory trance, to establish characteristics of compensatory illumination. Compensatory illumination may occur in a state of a particular type of trance. Therefore, the article tries to look at the relationship of compensatory trance and compensatory illumination.

<p>Dividend policy of firms is one of the most controversial issues of theoretical finance. This paper aims to investigate the firm-level factors influencing the dividend decisions of firms from an emerging market. We examined eight-year panel data for the period from 2006 to 2013 from the Turkish stock market (Borsa Istanbul). The results show that financial leverage, size, growth rate, age, profitability, ownership structure and P/E ratio are statistically significant. The relationship of leverage, growth rate, profitability and family control with dividends is negative, whereas the relationship of size, age and P/E ratio is positive. Therefore, firms with higher debt ratios / growth rates / higher earnings are likely to retain more of their earnings. The empirical evidence from the Turkish stock market shows that the maturity hypothesis proposed by Grullon, Michaely and Swaminathan (2002) best explains the dividend behaviors of firms. Accordingly, as a firm matures, the availability of profitable projects reduces and earnings decrease. As the investment opportunities reduce, the need for resources decreases and the firm increases dividend payouts to shareholders.</p>

There is little information available on the effect of growth rate on muscle distribution in sheep. Although Lohse, Moss & Butterfield (1971) and Lohse (1973) have reported data on muscle distribution of Merino sheep, the growth rates of animals in both these studies were neither controlled nor reported. In another experiment using Merino sheep, Lohse, Pryor & Butterfield (1973) studied the effect of a period of live-weight loss on the relationship of selected muscles to total side muscle during subsequent re-alimentation. They found that the interrupted growth path decreased the proportion of total side muscle formed by the weight of ten muscles which had previously been classified as muscles with a high growth impetus (Lohse, 1971). Data are presented herein for the muscle distribution of sheep grown along three growth paths.
