Persepsi Masyarakat Desa Penyangga terhadap Kawasan Taman Nasional Kerinci Seblat Pasca Pelaksanaan Kegiatan Konservasi Terpadu : Studi Kasus di Desa Napal Licin dan Desa Pulau Kidak, Kecamatan Ulu Rawas, Kabupaten Musi Rawas, Propinsi Sumatera Selatan

Selama tahun 1998-2002, Bank Dunia melalui Global Environment Facility (GEF) bekerja sama dengan Departemen Kehutanan dan Departemen Dalam Negeri dan Otonomi Daerah melakukan kegiatan Program Konservasi dan Pembangunan Terpadu (Integrated Conservation and Development Program/ICDP) di Taman Nasional Kerinci Seblat. Penelitian ini dilakukan untuk mengetahui dampak pelaksanaan program tersebut terhadap persepsi masyarakat di 2 desa mengenai keberadaan TNKS. Penelitian dilakukan di desa Napal Licin dan Desa Pulau Kidak, Kecamatan Ulu Rawas, Kabupaten Rawas Ulu, Provinsi Sumatera Selatan. Metodologi penelitian yang digunakan adalah metode survey rumah tangga dengan menggunakan kuisioner. Hasil penelitian ini menunjukkan bahwa program ICDP belum mampu merubah persepsi masyarakat terhadap keberadaan kawasan TNKS

Effect of magnesium doping on the orbital and magnetic order in LiNiO2

In LiNiO2, the Ni3+ ions, with S=1/2 and twofold orbital degeneracy, are arranged on a trian- gular lattice. Using muon spin relaxation (MuSR) and electron spin resonance (ESR), we show that magnesium doping does not stabilize any magnetic or orbital order, despite the absence of interplane Ni2+. A disordered, slowly fluctuating state develops below 12 K. In addition, we find that magnons are excited on the time scale of the ESR experiment. At the same time, a g factor anisotropy is observed, in agreement with $| 3z^{2}-r^{2}>$ orbital occupancy

RESULTS OF TWO DECADES OF RESEARCH WORK ON STABILISATION AND AGRICULTURAL REVALUATION OF AN APPROPRIATED LANDSLIDE

Starting with 1976, a totally unproductive piece of land located in the Chinteni Valley, Cluj County, severely degraded by landslides, was used as an experimental field in order to study the actual possibilities of agricultural reinstatement of these lands. Out of a large range of problems studied since then, the present paper shows the most important experimental results concerning the gradual stabilisation and agricultural revaluation of landslides by means of hydro- and agroappropriative works applied. The presented results emphasise the fact that as a consequence of appropriation works applied to this landslide (drainage and levellment) as well as by using crop technologies specific for slopes, the horizontal and vertical displacements of ground have been significantly reduced. Gradually, there has been noted an obvious tendency of a long term land stabilisation followed by a natural incorporation of this land into the equilibrium condition of the slope to which it belongs

3D Quantification of Vascular-Like Structures in z Stack Confocal Images

Optical slice microscopy is commonly used to characterize the morphometric features of 3D cellular cultures, such as in vitro vascularization. However, the quantitative analysis of those structures is often performed on a single 2D maximum intensity projection image, limiting the accuracy of data obtained from 3D cultures. Here, we present a protocol for the quantitative analysis of z stack images, utilizing Fiji, Amira, and WinFiber3D. This protocol facilitates the in-depth examination of vascular-like structures within 3D cell culture models

In vitro pre-vascularisation of tissue-engineered constructs A co-culture perspective

In vitro pre-vascularization is one of the main vascularization strategies in the tissue engineering field. Culturing cells within a tissue-engineered construct (TEC) prior to implantation provides researchers with a greater degree of control over the fate of the cells. However, balancing the diverse range of different cell culture parameters in vitro is seldom easy and in most cases, especially in highly vascularized tissues, more than one cell type will reside within the cell culture system. Culturing multiple cell types in the same construct presents its own unique challenges and pitfalls. The following review examines endothelial-driven vascularization and evaluates the direct and indirect role other cell types have in vessel and capillary formation. The article then analyses the different parameters researchers can modulate in a co-culture system in order to design optimal tissue-engineered constructs to match desired clinical applications

q-Deformed quaternions and su(2) instantons

We have recently introduced the notion of a q-quaternion bialgebra and shown its strict link with the SO_q(4)-covariant quantum Euclidean space R_q^4. Adopting the available differential geometric tools on the latter and the quaternion language we have formulated and found solutions of the (anti)selfduality equation [instantons and multi-instantons] of a would-be deformed su(2) Yang-Mills theory on this quantum space. The solutions depend on some noncommuting parameters, indicating that the moduli space of a complete theory should be a noncommutative manifold. We summarize these results and add an explicit comparison between the two SO_q(4)-covariant differential calculi on R_q^4 and the two 4-dimensional bicovariant differential calculi on the bi- (resp. Hopf) algebras M_q(2),GL_q(2),SU_q(2), showing that they essentially coincide.Comment: Latex file, 18 page

Functional status and oral health in patients with amyotrophic lateral sclerosis: A cross-sectional study

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting upper and lower motor neurons. The current practice of caring for patients affected by ALS involves a multidisciplinary team without any indication about oral health care. OBJECTIVE: We sought to investigate the functional status and oral health in patients with ALS to define a specific multidisciplinary management. METHODS: In this cross-sectional study, we included patients affected by ALS, evaluating their functional status, using the Revised ALS Functional Rating Scale (ALSFRS-R) and their oral health status through specific parameters, including Brief Oral Health Status Examination (BOHSE), Winkel Tongue Coating Index (WTCI), and Oral Food Debris Index (OFDI). RESULTS: All 37 patients (mean age: 61.19±11.56 years) showed a poor oral status, independent from the functional status and strictly correlated to the severity of sialorrhea (p=0.01). OFDI index was negatively correlated with the ALSFRS-R upper limb (p=0.03). Patients with bulbar onset had significantly lower ability to perform adequate tongue movements in terms of protrusion (p=0.006) and lateralization (p<0.001). Significant negative correlations between survival rate and BOHSE (p=0.03) was found. CONCLUSIONS: Taken together, our findings showed that a poor oral health status might be correlated to a worse functional status and survival time. Thus, an adequate oral health care and rehabilitation should be considered as crucial in the multidisciplinary management of patients with ALS

Atrial expression of the CCN1 and CCN2 proteins in chronic heart failure

Previous studies have reported the upregulation of CCN proteins early after acute heart injury. The aim of the present work was to evaluate the expression of the CCN1 and CCN2 proteins and their regulation by angiotensin II in the atrial myocardium of a chronically failing heart. Male adult mice were subjected to ligation of the left coronary artery to produce myocardial infarction (the MI group), and 16 of them were treated for 12 weeks with the AT1 receptor antagonist telmisartan (the MI-Tel group). Sham-operated mice served as controls. The expression of proteins was evaluated by immunohistochemistry 12 weeks after the operation. In shamoperated mice, stainings for CCN1 and CCN2 proteins were positive within atrial cardiomyocytes. CCN1-positive reaction revealed diffused cytoplasmic localization, while CCN2 was present mainly within the perinuclear cytoplasm. CCN1 was upregulated in the MI group, while CCN2 remained at basal level. Telmisartan prevented the upregulation of CCN1 and decreased CCN2 level. We compared the experimental data with the expression of CCN1 and CCN2 proteins in human right atrial appendages. We found an inverse, but not significant, relation between the level of either protein and the left ventricular ejection fraction. This suggests a similar atrial regulation of CCN1 and CCN2 expression also in humans. We conclude that in the murine atria, CCN1 and CCN2 proteins are expressed constitutively. In chronic heart failure, CCN proteins tend to be upregulated, which may be related to the action of angiotensin II
