The Malakasiotiko stream is one of the tributaries of Pinios River in Western Thessaly. The drainage basin of Malakasiotiko stream is located in the northwestern part of the mountainous zone of Trikala Prefecture. In this paper, the drainage network of Malakasiotiko stream has been analyzed. Additionally, the relationship among the tectonism, the growth directions of the watershed lines, and the drainage network. The quantitative analysis of the drainage network has resulted that the geological and tectonic structure of the area affected, and potentially has been affecting its development. The morphotectonic analysis has shown that the watershed lines of the drainage basin and the streams of 1st to 4th order are influenced by alpine structure, whereas the 5th, 6th and the 7th order streams are influenced by neotectonic activity.

The Kleinovitikos stream is a tributary ofPineios River in the Western Thessaly. Its basin drainages parts of mountain range of Southern Pindos as well as the mountain of Koziaka. In this study a quantitative analysis of drainage network was accomplished and the relation of tectonics features with the watershed and the channels of drainage network were investigated. The main channel of the drainage network is of 6th order, while the dominated type of the network is the trellis drainage pattern. The morphological slopes of the basin show various fluctuations. The gentle slopes express erosional landforms while the steep ones represent geological and tectonic structures. It was noted by the quantitative analysis of the drainage network that the geological and tectonic structure of the area affects in its evolution. Moreover, the outcrop of heterogeneous lithological formations in the basin affects the values of drainage density and frequency. The lithology and the secondary cracks involve in the prevailing direction of the watershed. The streams of 1st -3r order are controlled by the younger cracks; the younger cracks as well as the older Alpine cracks have an influence on the streams of 4' and 5' order, and the Alpine tectonic activity affects the stream of 6' order.

River Drainage Basin

Portaikos river is a tributary of Pinios River located in Thessaly. It drains the southern part of Thessaly basin, and specifically the south part of the district of Tricala. This region is located at the border with the district of Karditsa. Portaikos River drainage basin covers an area of 294 km2, which is 2.8 % of the total drainage basin of Pinios River. The direction of Portaikos river drainage basin extends from SW-NE. The evolution of Portaikos River drainage network presents some specific morphometric features. Its analysis required the use of digital data, which were analyzed with G.I.S. software. During the study of the drainage network with the laws of drainage composition, we found a certain deviation of the 4t h and 5t h order streams. Geology has influenced significantly the estimated values of drainage density and frequency of the sub-basins. In some specific areas previous hydrographie features are inherited by the underlying rocks, which constitute the current surface morphology. The analysis of the rose diagrams of the tributaries showed a clear tendency in two main directions. The one extends from NE-SW and the other from NW-SE, almost vertical to each other. To conclude, the hypsometric (area altitude) analysis revealed that Portaikos River drainage network has developed upon a landmass of the western tectonic border of Thessaly basin.

In this paper the relationship between the morphometric parameters of a drainage system and the neotectonic activity is investigated. The hydrographie network of the Upper Acheloos River was chosen as the study area. The whole network and especially its western-southwestern part appears to be in the rejuvenated stage of evolution, as it is concluded by the analysis of the parameters, associated with the shape and slope of the basins, and the slope of the respective streams. Furthermore, the shape of the drainage network and the structure of the basins suggest that not only the Alpine orogenesis but also the neotectonic activity controls the morphogenetic processes in the area

Whitsleblowing is one of the positive practices in organizations that are able to raise the level of integrity among the members of an organization. However, the roles of whistleblowing also inevitably invites a response, especially among members of the organization itself. This is because such practices are viewed as one factor that may be detrimental to the organization in addition to revealing the reporter (whistleblower) to some external threats and intimidation of discrimination within the organization. This paper is an attempt to examine the relationship between perceptions of members of the Royal Malaysian Police (RMP) Contingent of Perak through the role of whistleblowing practices to increase the perception of the integrity of the members. Next, identify the purpose of the whistleblowing and its effect on the integrity of the members of the organization. This study used a descriptive quantitative analysis to identify patterns of relationship that exists between the perception of whistleblowing practices with perceptions of increased integrity based on three basic variables of demographic factors, response to whistleblowing and the impact of making the report. The results showed that members of the Perak’s police have a positive perception of whistleblowing practices which are seen to be done in improving the integrity of the members.Keywords: whistleblowing, perception, RMP members, culture, integrity, organization, influence. ABSTRAK: Whitsleblowing merupakan salah satu amalan positif dalam organisasi yang mampu untuk meningkatkan tahap integriti ahli-ahli dalam sesebuah organisasi. Namun begitu, amalan whistleblowing juga turut tidak dapat mengelak daripada mengundang pelbagai respon khususnya dalam kalangan ahli organisasi itu sendiri. Amalan sebegini turut dilihat sebagai salah satu faktor yang boleh memudaratkan organisasi di samping mendedahkan pelapor (whistleblower) kepada beberapa bentuk ancaman ugutan dari luar dan diskriminasi dalam organisasi. Kertas ini merupakan satu upaya untuk melihat perkaitan antara persepsi anggota Polis Diraja Malaysia (PDRM) Kontinjen Perak melalui peranan amalan whistleblowing terhadap persepsi peningkatan integriti anggota. Seterusnya, mengenalpasti maksud whistleblowing dan pengaruhnya terhadap tahap integriti anggota dalam organisasi. Kajian ini menggunakan analisis kuantitatif berbentuk deskriptif bagi mengenalpasti corak hubungan yang wujud antara persepsi terhadap amalan whistleblowing dengan persepsi terhadap peningkatan integriti berdasarkan tiga pembolehubah asas iaitu faktor demografi, tanggapan terhadap whistleblowing dan kesan daripada tindakan membuat laporan. Dapatan kajian menunjukkan bahawa anggota PDRM Perak mempunyai persepsi yang positif terhadap whistleblowing yang mana ianya dilihat perlu dilaksanakan dalam meningkatkan integriti anggota.Kata kunci: whistleblowing, persepsi, amalan, anggota PDRM, budaya, integriti, organisasi, pengaruh.

Modern Earth Scientists need also to interact with other disciplines, apparently far from the Earth Sciences and Engineering. Disciplines related to history and philosophy of science are emblematic from this perspective. From one side, the quantitative analysis of information extracted from historical records (documents, maps, paintings, etc.) represents an exciting research topic, requiring a truly holistic approach. On the other side, epistemological and philosophy of science considerations on the relationship between geoscience and society in history are of fundamental importance for understanding past, present and future geosphere-anthroposphere interlinked dynamics.

Abstract. Adipocytes from streptozotocin-diabetic rats showed a markedly reduced lipolytic response to glucagon concomitant with a 90% or greater decrease in the number of glucagon receptors per cell. In contrast, β-adrenergic receptors assessed by [3H]dihydroalprenolol binding and lipolysis stimulated by isoproterenol, dibutyryl 3′5′-cyclic AMP and 3-isobutyl-1-methylxanthine were reduced by only 10–25% in diabetic rats compared with controls. Furthermore, quantitative analysis of the relationship between the amount of cell-bound glucagon and the hormone-stimulated lipolysis revealed that the function of the remaining 10% of glucagon receptors remained intact in cells from diabetic animals. These findings suggest that the lipolytic cascades, including β-adrenergic receptors, in adipocytes are not greatly impaired by diabetes, and therefore, the unresponsiveness of these cells to glucagon is mostly due to a marked reduction in the number of glucagon receptors, probably as a result of a down-regulation by postprandial hyperglucagonemia.

The Relationship

A new treatment is proposed for quantitative analysis of two-component polymer systems by infrared spectroscopy. Like much previous work, it is based on a ratio involving two peaks in the same spectrum. The relationship between such a ratio and the concentration of a given polymer is inherently nonlinear. It is shown that this nonlinearity can be well described by a simple equation derived from the laws of optical transmission. This equation has the form χ1 = m1 + m2 R/(1 + m3 R), where χ1 is the weight fraction of polymer 1, the mi are adjustable coefficients, and the ratio R is equal to Aa/( Aa + Ab). The quantities Aa and Ab are the absorbances (peak heights or areas) at two frequencies a and b of which the first is associated mainly with polymer 1 and the second with polymer 2. This equation has been applied to various peak combinations in spectra of miscible blends of poly(phenylene ether) with polystyrene (both mid-IR and near-IR data) and immiscible blends of polypropylene with polyethylene (mid-IR data). It is shown that the equation is valid in all cases, covering the full concentration range from 0 to 100% even when the peaks used for the analysis involve absorption by both polymers. It is therefore believed to be of broad general usefulness for the analysis of polymer blends and copolymers.
