Anthropic pressures on Nature 2000 Sites: recommendations and monitoring criteria for the pollution emergency response activities within the Orbetello lagoon

L’elevato valore naturalistico e socioeconomico di un Sito Natura 2000 richiede che tutte le attività antropiche che si svolgono al suo interno (es. pesca, turismo, trasporti, attività industriali, etc.) siano gestite in maniera tale da non pregiudicare le specie e gli habitat per i quali l’area è stata designata. Molti di questi Siti sono ambienti di transizione, ovvero zone che costituiscono il passaggio naturale tra terra e mare. La loro posizione di interfaccia tra questi due ambienti li rende ecosistemi unici e biologicamente molto produttivi, sede di meccanismi di regolazione dei processi interattivi della biosfera nelle due fasi, terrestre e marina. In alcuni Siti la presenza di attività antropiche diffuse e prolungate nel tempo ha portato al riscontro di stati di contaminazione elevata, fino all’inclusione di queste zone, o parti di esse, tra i Siti di bonifica di Interesse Nazionale (SIN). Il presente lavoro descrive le linee di indirizzo e le attività di monitoraggio da attuare per la salvaguardia della salute pubblica e dell’ambiente nel corso degli interventi di messa in sicurezza di emergenza predisposti nell’area lagunare antistante l’area industriale Ex Sitoco, all’interno della perimetrazione del SIN di Orbetello, incluso in un Sito di Importanza Comunitaria. Le matrici ambientali potenzialmente a rischio a causa dell’esecuzione di tali interventi sono: acqua, sedimento, biocenosi acquatiche, avifauna, uomo. È altresì importante valutare gli effetti che le ipotetiche modifiche su microscala, apportate a livello di ogni matrice, potrebbero causare nel lungo periodo su macroscala.The high naturalistic and socio-economic value of Natura 2000 sites requires that all human activities performed within their borders (e.g. fishing, tourism, transports, industrial activities) are regulated. Indeed, the site management should assure the effective safeguard of all species and habitats of European interest included in the protected area. A lot of such sites are located in transitional environments, that are areas characterised by a natural progression from the terrestrial to the water environments. Such environments include unique and very productive habitats, and they represent the regulation mechanisms of the interactive processes of the terrestrial and marine biosphere. In some sites, the presence of human activities that are distributed both in space and time has led to high levels of contamination, that in some cases even required their inclusion in Reclamation Sites of National Interest (SIN). The present study describes the planning and monitoring activities to be performed in order to safeguard human and environment health during the actions of MISE in the lagoonal area in front of the industrial area Ex Sitoco, within the borders of the Orbetello SIN, included in a SCI. The environmental parameters that are potentially at risk due to such activities are: water, sediment, water biocenosis, birds, humans. Furthermore, it is important to evaluate the effects that potential variations at the microscale level may cause at the macroscale level

Masalah yang menjadi kajian pada penelitian ini bagaimana implementasi manajemen pembinaan perpustakaan kelurahan di Kota Bandung oleh Dispusip Kota Bandung. Tujuan penelitian ini yaitu untuk mendeskripsikan mengenai perencanaan, pengorganisasian, penggerakan dan pengawasan pembinaan perpustakaan kelurahan oleh Dispusip Kota Bandung. Metode yang digunakan pada penelitian ini adalah metode kualitatif dengan pendekatan studi kasus. Partisipan dalam penelitian ini terdiri atas tiga informan yang bertindak sebagai pustakawan dan key informan sebagai Kepala Bidang Pengembangan Perpustakaan dan Kearsipan menggunakan teknik purposive sampling. Instrumen penelitian yang digunakan adalah wawancara, observasi dan studi dokumentasi. Teknik analisis data yang digunakan adalah data reduction, data display, dan conclusion drawing (verification). Berdasarkan hasil penelitian yaitu sebuah konstuksi model manajemen pembinaan perpustakaan kelurahan yang menunjukkan bahwa kegiatan pembinaan perpustakaan kelurahan oleh Dispusip Kota Bandung relevan dengan fungsi manajemen. Fungsi perencanaan, pengorganisasian, penggerakan kegiatan manajemen pembinaan perpustakaan kelurahan di Kota Bandung terealisasi cukup baik. Namun pada fungsi pengawasan belum berjalan secara optimal, hal ini dikarenakan oleh keterbatasan sumber daya manusia yang dimiliki oleh Dispusip Kota Bandung. Program pembinaan ini diharapkan dapat mewujudkan penyelenggaraan perpustakaan kelurahan dan dapat memberikan kontribusi terhadap perbaikan/ penyempurnaan manajemen pembinaan perpustakaan oleh Dispusip Kota Bandung. ;--- Dinas Perpustakaan dan Kearsipan (Dispusip) Kota Bandung is a form of public library, which function is to develop urban village libraries. Currently, the empowerment of urban village libraries in 151 village in Bandung City is not realized yet. Urban village libraries can perform its functions properly in accordance with the implementation of library management functions. The problem of this study is how Dispusip Kota Bandung manages the implementation of urban village libraries coaching in Bandung City. The purpose of this study is to describe the planning, organizing, actuating, and controlling of urban village libraries coaching by Dispusip Kota Bandung. The research method used in this study is qualitative method with a case study approach. The subjects of this study consist of three informants who act as a librarian and a key informant as a Head of Library and Archive Development by using purposive sampling technique. The research instruments used in this study are interviews, observations, and documentation studies. This study uses data analysis technique of data reduction, data display, and conclusion drawing (verification). Based on the study of a model construction of urban village libraries coaching, the result is that the coaching activities of urban village libraries done by Dispusip Kota Bandung is relevant to the management functions. The functions of planning, organizing, and actuating of village libraries coaching activities in Bandung City are realized quite well. However, the function of controlling has not run optimally. This is due to the limitations of human resources owned by Dispusip Kota Bandung. This coaching program is expected to be able to realize the enforcement of urban village libraries and to give contribution to the improvement of library coaching management done by Dispusip Kota Bandung

Exercise respiratory cycle time components in patients with emphysema

Background: We have recently demonstrated that in patients with COPD the severity of emphysema (E) measured by high resolution computed tomography (HRCT) correlated with: ratio VTpeak/FEV1; VE/VCO2 slope and PETCO2 values at peak exercise. The aim of this study was to further investigate if exercise respiratory cycle time components correlated with % of E measured by HRCT. Method: Twelve patients (age = 65±8 yrs; FEV1 = 55±17%pred) with moderate to severe E (quantified by lung HRCT as % voxels < −910 HU) were evaluated with incremental cardiopulmonary exercise testing (CPET). Mean inspiratory time (TiM), mean total respiratory cycle time (TtotM), mean expiratory time during exercise (TeM) and mean expiratory time during the last third of exercise (TeM-end), has been calculated. Results: Both TeM and TeM-end had a good linear correlation with % of E (r = 0,61; p = 0,004 and r = 0,63; p = 0,003). Moreover, by dividing the patients in two groups based on the % of E (>50% and <50%), we observed that patients with higher % of E had longer TeM (TeM: 1,72±0,26sec vs 1,34±0,27sec, p = 0,005) and TeM-end. A good linear correlation has been observed also between TeM and PETCO2 and VE/VCO2 (r = 0,64; p = 0,002 and r = 0,7; p = 0,0005). TeM did not correlated with resting lung function values or inspiratory capacity (IC). Conclusion: The data confirm that distinct physiologic response pattern can be detected at CPET in these patients

Efficacy of pulsatile flow perfusion in adult cardiac surgery: Hemodynamic energy and vascular reactivity

Background: The role of pulsatile (PP) versus non-pulsatile (NP) flow during a cardiopulmonary bypass (CPB) is still debated. This study’s aim was to analyze hemodynamic effects, endothelial reactivity and erythrocytes response during a CPB with PP or NP. Methods: Fifty-two patients undergoing an aortic valve replacement were prospectively randomized for surgery with either PP or NP flow. Pulsatility was evaluated in terms of energy equivalent pressure (EEP) and surplus hemodynamic energy (SHE). Systemic (SVRi) and pulmonary (PVRi) vascular resistances, endothelial markers levels and erythrocyte nitric-oxide synthase (eNOS) activity were collected at different perioperative time-points. Results: In the PP group, the resultant EEP was 7.3% higher than the mean arterial pressure (MAP), which corresponded to 5150 ± 2291 ergs/cm3 of SHE. In the NP group, the EEP and MAP were equal; no SHE was produced. The PP group showed lower SVRi during clamp-time (p = 0.06) and lower PVRi after protamine administration and during first postoperative hours (p = 0.02). Lower SVRi required a higher dosage of norepinephrine in the PP group (p = 0.02). Erythrocyte eNOS activity results were higher in the PP patients (p = 0.04). Renal function was better preserved in the PP group (p = 0.001), whereas other perioperative variables were comparable between the groups. Conclusions: A PP flow during a CPB results in significantly lower SVRi, PVRi and increased eNOS production. The clinical impact of increased perioperative vasopressor requirements in the PP group deserves further evaluation
