Ectoedemia argyropeza on Aspen leaves: deciphering retrospectively some behavioural traits from the distribution of traces of the insect activities subsisting on host-leaves (Lepidoptera, Nepticulidae). Despite their usually small size, endotrophic insects —especially those whose larvae are mining into their host-leaves— exhibit patterns of behaviour that are often more elaborate than what is usually seen in many ectotrophic herbivorous insects. However, since it is generally difficult to capture properly these behaviours in the field, precisely due to the small size of these insects, it turns out to be more convenient attempting to uncover retrospectively some of these behaviours on the basis of their resulting traces which subsist on the host-leaves. In order to be able to infer reliable information from this retrospective approach, the examination of a substantial number of host leaves and the support of appropriate statistical tests are required. The present study concerns a species of microlepidoptera, Ectoedemia argyropeza, whose caterpillars are exclusively mining the leaves of Aspen (Populus tremula) and which is still further distinguished, in a remarkable manner, by the induction of a preliminary galling (“cecidian”) development stage. This unusual combination of life traits contributes to enrich the insect’s behavioural repertoire and therefore offers a more promising field of investigation. For this species, I more particularly focus on the way the artefacts resulting from the insect activities are distributed spatially, on (or in) the host leaf, namely: (i) the spatial distribution of eggs deposited on the host-leaf petiole, (ii) the hierarchy of preferential positioning of the caterpillar corridor in the section of the petiole, hypertrophied by the cecidogenic reaction, (iii) the hierarchy of preferential locations of mines in the host-leaf blade. Were also tested, on the one hand, the existence (or not) of paired relationships between each of the three categories of distributions mentioned above and, on the other hand, the degree of conformation of each of these different distributions to the bilateral symmetry of the leaf support. The behavioural aspects that can be tentatively inferred from the above information are subsequently discussed.

Renal Disease was a chronic disease that the most attacking people in Indonesia. Damage to this vital organ in the human body greatly affected a person's health condition, one of which was anemia. This study aimed to determine the effectiveness of Durante hemodialysis PRC transfusions on hemoglobin levels. The method used was Pre-experimental design, with the One group pre-post test design approach. With a sample of 49 patients who underwent regular hemodialysis at RSUD dr. Iskak Tulungagung. Data were obtained by direct observation. Processed by computerized methods with a statistical t-test, the significance level (α) was 0.05. The study results showed that the hemoglobin levels of the pre-Durante hemodialysis PRC transfusion patients were 4-5 mg/dl (53.06%), and the hemoglobin levels of the post-Durante hemodialysis PRC transfusion patients were 6.1-7 mg/dl (34.69%). The results of statistical tests showed that there was an increase in hemoglobin levels in patients who received Durante hemodialysis PRC transfusion by 1.22 mg/dl because p-value = 0.000 < 0.05 (α) means that there was an effect. It could be concluded that the delivery of Durante hemodialysis PRC transfusion could help increase hemoglobin levels. This finding was very helpful for chronic Renal Disease patients undergoing hemodialysis, who have been using erythropoietin preparations because PRC transfusions were cheaper and more effective when compared to using erythropoietin preparations

The problem of constructing effective statistical tests for random number generators (RNG) is considered. Currently, there are hundreds of RNG statistical tests that are often combined into so-called batteries, each containing from a dozen to more than one hundred tests. When a battery test is used, it is applied to a sequence generated by the RNG, and the calculation time is determined by the length of the sequence and the number of tests. Generally speaking, the longer is the sequence, the smaller are the deviations from randomness that can be found by a specific test. Thus, when a battery is applied, on the one hand, the “better” are the tests in the battery, the more chances there are to reject a “bad” RNG. On the other hand, the larger is the battery, the less time it can spend on each test and, therefore, the shorter is the test sequence. In turn, this reduces the ability to find small deviations from randomness. To reduce this trade-off, we propose an adaptive way to use batteries (and other sets) of tests, which requires less time but, in a certain sense, preserves the power of the original battery. We call this method time-adaptive battery of tests. The suggested method is based on the theorem which describes asymptotic properties of the so-called p-values of tests. Namely, the theorem claims that, if the RNG can be modeled by a stationary ergodic source, the value − l o g π ( x 1 x 2 … x n ) / n goes to 1 − h when n grows, where x 1 x 2 … is the sequence, π ( ) is the p-value of the most powerful test, and h is the limit Shannon entropy of the source.

Sodium Azide Induced Morphological and Molecular Changes in Persimmon (Diospyros LotusL.)PersimmonDiospyros lotusL. is an underutilized species, used as rootstock for Japanese persimmon (Diospyros kakiThunb.) in many European countries. It has a potential for ornamental uses due to its diploid genome that suggests an easy mutation induction. This study was aimed at unravelling the effects of mutagenic sodium azide (in concentrations of 0.1% and 0.5%) on morphological characters (plant height, maximal leaf blade length, maximal leaf blade width and leaf petiole length) and molecular relations of treated accessions, based on AFLP (amplified fragment length polymorphism). In the M1 generation, the analysed characters of two-year old plants differed among the treatments. Sodium azide influenced persimmon stem and leaves in the opposite way, with increase up to 31.57% in plant height and decrease up to 30.33% in leaf petiole length. Changes in morphological characters were significant, that implies the importance of azide influence on the persimmon. Most genotypes treated with 0.1% azide were without significant differences among them and clustered together. The results suggest that the higher azide concentration of 0.5% is more suitable for persimmon seeds azide treatment to form genotypes, significantly different from the control, at the molecular level.

This paper aims to provide an insight to later researchers on the application of axiomatic design in the area of design for end-of-life (EOL) management. Among all life cycle stages of a product, design and development stage is the one that influences the later stages the most in terms of environmental impacts. In order to achieve sustainable product development, one of the considerations to be taken during the design stage is EOL management. EOL management process can be enhanced by utilizing a robust design method as well as an effective method for evaluating product design. Recent researches show that application of axiomatic design in the field of eco-design (especially design for EOL management) is still in a premature stage despite having a vast application area that covers the aspect of product design, manufacturing and supply chain management. Nonetheless, a case study published recently on eco-design using axiomatic approach has shown adequate feasibility and effectiveness. Therefore, design for sustainable EOL using axiomatic approach is worth further exploration.

Twelve species of flowering potted plants were grown in a peat-based medium with water soluble fertilizer concentrations of 50, 100, or 200 mg·liter-1 N and K2O. Leaf blade or leaf petiole samples were collected six to eight weeks after planting. Sap was expressed using a hydraulic press and levels of nitrate nitrogen and potassium were determined using Cardy flat sensor ion meters. Petiole nitrate level ranged from 520 to 6300 mg·liter-1 and potassium levels ranged from 870 to 3600 mg·liter-1. The petiole nitrate concentration and change in petiole nitrate levels with changes in media nitrate levels was crop dependent. Leaf blade nitrate and potassium concentrations were lower than leaf petiole concentrations. The relationship of petiole nitrate to final plant fresh and dry mass and appearance at flowering will be presented.

Abstract Background: Interdisciplinary scientific areas regularly develop unique methodologies, yet utilise the conventional communication modes to disseminate results of their researches. Objectives: This paper analyses whether a novel, interdisciplinary communication mode can be found in a gradually developing interdisciplinary journal. Methods/Approach: The content of the journal was categorised based on the characteristics attributed to the published papers. Statistical tests were performed to check for the overlapping categories. Results: A number of indicators, related to papers or to their authors, are introduced and quantified. Conclusions: Methodology utilised and data collected serve, on the one hand, as a referent set for treating the content of other interdisciplinary or disciplinary scientific journals, and, on the other hand, as a set for comparison and extraction of universalities or specificities of the journals. Fluctuations accompanying a gradual rise of the considered journal content prevent a definite answer to the question whether there are some emerging interdisciplinary communication novelties.

It is widely accepted that empirical research methods and statistics belong together. This is no different in phraseology. In contrast to the natural and social sciences however, no standardized statistical culture has yet emerged in this field. Empirical research in German phraseology during the last 15 years shows a variety of approaches and analysis methods, which often led to contradictory results. Part of this dilemma can be explained by the fact that statistical methods were ignored, too few participants were involved in the studies, the participants chosen were not representative for the intended group or the statistical tests were improperly used. This article gives a basic introduction to the main statistical tests needed in phraseological research (i. e. chi-square test, t-test, analysis of variance and regression) and clear instructions on when and how to use them. Special attention is drawn to the importance of interactions between different factors (that can be tested with the help of analysis of variance). With this article I hope to have been able to demonstrate that statistics are a necessary tool in phraseology and other linguistic disciplines: on the one hand to organize and to clearly present the data and on the other hand to provide more evidence for regularities in the data.
