The Relationship

Summary The present paper establishes the relationship between certain components of oleoresin and the character of a tree as high producer (plus tree). The composition of the oleoresin (monoterpenes, sesquiterpenes, neutral diterpenes and resin acids) of Pinus pinaster in plus trees was studied by gaschromatography/mass spectrometry. The main components of the monoterpenes are α-pinene, β-pinene, limonene + β-phellandrene; of the sesquiterpenes β-caryophylene and longifolene; of neutral diterpenes isoabienol, abienol, isopimaral, pimaral, 11,13-labdien-8-ol and of resin acids levopimaric + palustric, neoabietic, abietic, isopimaric, pimaric, dehydroabietic, sandaracopimaric and 7,13,15 abietatrienoic acid. The components which enable us to distinguish between plus and control trees are myrcene and noracid 1 at a level of significance of 1%, and abienol and dehydroabietic acid at 5%. The composition of diterpenes permits a certain approach to distinguish between control and plus trees.

The chemical composition of lipophilic bark extracts from Pinus pinaster and Pinus pinea cultivated in Portugal was evaluated using gas chromatography-mass spectrometry. Diterpenic resin acids were found to be the main components of these lipophilic extracts, ranging from 0.96 g kg−1 dw in P. pinea bark to 2.35 g kg−1 dw in P. pinaster bark. In particular, dehydroabietic acid (DHAA) is the major constituent of both P. pinea and P. pinaster lipophilic fractions, accounting for 0.45 g kg−1 dw and 0.95 g kg−1 dw, respectively. Interestingly, many oxidized compounds were identified in the studied lipophilic extracts, including DHAA-oxidized derivatives (7-oxo-DHAA, 7α/β-hydroxy-DHAA, and 15-hydroxy-DHAA, among others) and also terpin (an oxidized monoterpene). These compounds are not naturally occurring compounds, and their formation might occur by the exposure of the bark to light and oxygen from the air, and the action of micro-organisms. Some of these compounds have not been previously reported as lipophilic constituents of the bark of the referred pine species. Other constituents, such as aromatic compounds, fatty acids, fatty alcohols, and sterols, are also present in the studied extracts. These results can represent an opportunity to valorize P. pinaster and P. pinea by-products as a primary source of the bioactive resin acids that are integrated into the current uses of these species.

The Relationship

The prostate exam is an early detection tool to prevent prostate cancer and the main diagnostic tools for obtaining signs are generally invasive. This article tries chromatographic signals from the urine of prostate cancer patients and control patients as a non-invasive examination proposal. For this purpose, methodologically, urine samples are taken, digitized in chromatograms, treated with mathematical techniques and classified. The mathematical techniques are time normalization, dead time elimination, baseline correction, noise elimination, and peak alignment. Classification techniques analyze energy, in the domain of time and frequency, and the main components in sedimentation graphs and scores. As a result, the chromatographic signal is characterized and identifies the characteristic curve that represents the signal of prostate cancer patients and control patients. The data structure shows a cluster distribution of 88.88% of the vectors for the control patients. In the case of prostate cancer patients, the distribution of data is in clusters around the area defined by control patients. This characterization demarcates signal classification regions to diagnose possible prostate cancer patients, validating the relationship between the chromatographic signal and cancer.

Abstract:On-line intelligent monitoring, diagnosis, and control of dynamic systems such as patients in intensive care units necessitates the context-dependent acquisition, processing, analysis, and interpretation of large amounts of possibly noisy and incomplete data. The dynamic nature of the process also requires a continuous evaluation and adaptation of the monitoring strategy to respond to changes both in the monitored patient and in the monitoring equipment. Moreover, real-time constraints may imply data losses, the importance of which has to be minimized. This paper presents a computer architecture designed to accomplish these tasks. Its main components are a model and a data abstraction module. The model provides the system with a monitoring context related to the patient status. The data abstraction module relies on that information to adapt the monitoring strategy and provide the model with the necessary information. This paper focuses on the data abstraction module and its interaction with the model.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

The Relationship

Regional Regulation (Perda) which regulates public issues such as prostitution, alcoholic beverages, gambling, and the relationship between men and women turns out to be identified as a Regional Regulation with nuances of Islamic law. in Banyumas Regency there is a Regional Regulation which if used by the identification of Arfiansyah above, it can be referred to as a Regional Regulation with nuances of Islamic law. The regulation is: Banyumas District Regulation Number 15 of 2014 concerning Control, Supervision and Control of Circulation of Alcoholic Beverages and Regional Regulations of Banyumas Regency Number 16 of 2015 concerning Community Disease Management. This research has two formulations of the first problem related to the results of the content of the analysis on the Perda that are nuanced by Islamic law in Banyumas Regency. Both of the results of the analysis content on the Regional Regulations that are nuanced by Islamic law in Banyumas Regency are not contrary to Law-Invitation Number 12 of 2011? This research is a qualitative-descriptive study. The research method used is normative juridical. The main source of data is the Banyumas District Regulation Number 15 of 2014 concerning Control, Supervision and Control of Circulation of Alcoholic Beverages and Regional Regulations of Banyumas Regency Number 16 of 2015 concerning Community Disease Management. Interviews were also conducted with resource persons. Furthermore, the results of the analysis were carried out. Regional Regulation No. 15 of 2014 is actually a Regional Regulation that has a broad purpose of public interest, for the nation and state. So that the claim that Perda No 15 of 2014 as a Regional Regulation with nuances of Islamic law is not true. Regional Regulation No. 16 of 2015 is actually a Regional Regulation that has a broad purpose of public interest, for the nation and state. So that the claim that Perda No 16 of 2015 as a Regional Regulation with nuances of Islamic law is not true. Both of these Perda (Perda No 15 of 2014 and Perda No. 16 of 2015) are not in conflict with Law No. 12 of 2011 concerning the Establishment of Legislation. Both in terms of content, principles, goals, arrangements, administrative sanctions and criminal sanctions. Formally and procedurally the two Perda are in accordance with Law Number 12 of 2011

Theoretical Developments

Well-functioning financial markets can have a positive effect on economic growth by facilitating savings and more efficient allocation of capital. This paper characterises some of the recent theoretical developments that analyse the relationship between financial intermediation and economic growth and presents empirical estimates based on a model of the linkage between financially intermediated investment and growth for two separate groups of countries, developing and advanced. Empirical estimates for both groups suggest that financial intermediation through the efficiency of investment leads to a higher rate of growth per capita. The relevant coefficient estimates show a higher level of significance for the developing countries. This financial liberalisation in the form of deregulation and establishment and development of stock markets can be expected to lead to enhanced economic growth.
