Touristic urbanization and greening of coastal dune fields:A long-term assessment of a temperate sandy barrier of Argentina

引用

Journal of Geographical Sciences 2025年第1期35卷 206-230页

作者： GARZO pedro Andrés DADON José Roberto ISLA Federico Ignacio Instituto de Investigaciones Marinas y Costeras (IIMyC-CONICET/UNMDP) Instituto de Geología de Costas y del Cuaternario Dr.Enrique J.Schnack (IGCC-CIC/UNMDP) Universidad de Buenos Aires Facultad de Arquitectura Dise?o y Urbanismo Centro de Investigaciones Gestión de Espacios Costeros (GEC-FADU/UBA) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET)

Dune barrier systems represent highly sought-after coastal landscapes for tourism and urban development around the world. However, a century ago, they were considered hazardous environments due to their great dynamic nature. As a result, stabilization practices were considered necessary. The systematic introduction of fast-growing exotic trees helped stabilize the sand, making it easier for tourism urbanization to take place, but also leading to erosion processes. This paper aims to assess long-term changes in vegetation cover over a large temperate barrier in Argentina. This complex region includes urban resorts, afforestation zones, and protected areas. A GIS-based geospatial analysis was conducted using a large satellite database(> 350 images), and the future evolution of the vegetation was modeled. The results revealed two primary spatiotemporal patterns associated with a gradual expansion of vegetation cover, accompanied by a concurrent reduction in sandy areas. In 1986, the dune area comprised 75% more surface than vegetation, whereas in 2021, it represented 60% less than vegetation. Furthermore, the 2050 scenario suggests a potential 40% reduction of dunes in certain areas. It is necessary to enhance management actions aimed at maintaining dune mobility and ensuring local and regional sediment balance. Long-term management strategies must focus on restoring native plant communities and controlling invasive species, and avoiding new dune fixation initiatives based on the introduction of exotic species.

Journal of Integrative Agriculture 2015年第3期14卷 575-582页

Yeasts and organic minerals are used in diets to improve health, productive performance and some carcass characteristics of ruminants and non-ruminants. Thirty-two lambs（Pelibuey×Katahdin; BW=（30.55±1.67） kg; n=8） were used in a 56-d feeding experiment to study the effects of different levels of live yeast（Saccharomyces cerevisiae; yeast）, selenium（Se） and chromium（Cr） mixed（Se-Cr）, and a mixture of yeast-Se-Cr on growth performance and carcass traits. Animals were stratified by body weight（BW） and randomly assigned to one of four treatments： 1） control group（0.0 g kg–1 yeast）; 2） yeast（1.50 g kg–1 dry matter intake（DMI） d–1）; 3） Se-Cr premix（1.5 mg kg–1 DMI d–1 for each mineral）; and 4） yeast-Se-Cr mixture. There were no treatment effects on final BW; whereas lambs fed Se-Cr or yeast-Se-Cr had higher（P〈0.05） DMI than animals supplemented with only yeast. Average daily gain（ADG）, gain：feed ratio, chop area, dorsal fat and carcass yield were similar（P〉0.05） among treatment groups. In conclusion, supplementation with yeast, Se-Cr mixed or yeast-Se-Cr did not improve ADG, final BW, back fat content and carcass yield of growing of Pelibuey×Katahdin lambs. Supplementation with Se-Cr and yeast-Se-Cr increased DMI, and approximately 250 g ADG animal–1 d–1 was produced with no negative effects on growth and health of the animals.

A 43-year-old woman with an associated history of gynecological pathology and breast cancer with only one cryopreserved embryo wished to be a *** factors that influenced the success of the pregnancy in this case were analyzed. Favorable factors included: triple positive breast cancer [positive hormone receptors and positive human epidermal growth factor receptor 2],which is more hormosensitive and chemosensitive; absence of metastasis; correct endometrium preparation; and the patient's optimistic attitude and strict health habits. In contrast, the factors against success were: breast cancer; adjuvant breast cancer therapy gonadotoxicity; the age of the patient(> 40-year-old);endometriosis; ovarian cyst; hydrosalpinx; submucosal fibroids and the respective associated surgery done for the above-mentioned pathology(all resolved prior to the embryo transfer); and a low quantity of ovules(low ovarian reserve) after ovarian stimulation. This is a very special clinical case of a patient with theoretically low pregnancy success probability due to the consecutive accumulation of gynecological and oncological pathologies, who nonetheless became pregnant and delivered a full-term infant and was able to provide adequate breastfeeding.

Dear Editor,One of the most serious issues in modern oncology is the ineffectiveness of treatments in destroying tumours,which leads to tumour recurrence and,ultimately,patient *** phenomenon is caused by conventional therapies’fractional killing of tumour cells,which can also cause resistant cells to spread.1 We analysed chemotherapy-resistant cells and discovered that they are smaller than untreated cells(Fig.1a).The fact that this phenomenon occurs in all tested cell types(Hela,A549,Huh7,and MCF7)and regardless of the chemotherapy regimen(TRAIL,Camptothecin,Doxorubicin)suggests that it is a widespread phenomenon(Fig.1a,Supplementary Fig.S1).

Although pharmaceuticals have beendetected in the environment only in the range from ng/L to μg/L, it has beendemonstrated that they can adversely affect the health status of aquatic organisms. Lysosomal membrane stability （LMS） has previously been applied as an indicator of cellularwell-being todetermine health status in bivalve mussels. The objective of this study is to evaluate LMS in Ruditapes philippinarum haemolymph using the neutral red retention assay （NRRA）. Clamswere exposed in laboratory conditions to caffeine （0.1, 5, 15, 50 μg/L）, ibuprofen （0.1, 5, 10, 50 μg/L）, carbamazepine and novobiocin （both at 0.1, 1, 10, 50 μg/L） for35days. Results show adose-dependent effect of the pharmaceuticals. The neutral red retention time measured at the end of the bioassaywas significantly reduced by 50% after exposure to environmental concentrations （p 〈 0.05）（caffeine = 15 μg/L; ibuprofen = 10 μg/L; carbamazepine = 1 μg/L and novobiocin = 1 μg/L）, compared to controls. Clams exposed to these pharmaceuticalswere considered to present adiminished health status （retention time 〈45 min）, significantlyworse than controls （96 min）（p 〈 0.05）. The predicted no environmental effect concentration （PNEC） results showed that these pharmaceuticals are very toxic at the environmental concentrations tested. Measurement of the alteration of LMS has been found to be a sensitive technique that enables evaluation of the health status of clams after exposure to pharmaceuticals under laboratory conditions, thus representing a robust Tier-1 screening biomarker.

Security-constrained model for integrated power and natural-gas system

Journal of Modern Power Systems and Clean Energy 2017年第3期5卷 326-336页

One of the main factors impacting the reliability of energy systems nowadays is the growing interdependence between electricity and gas networks due to the increase in the installation of gas-fired units. Securityconstrained unit commitment(SCUC) models are used to economically schedule generating units without compromising the system reliability. This paper proposes a novel SCUC formulation that includes dynamic gas constraints,such as the line pack, and transmission contingencies in power and gas networks for studying the integrated system reliability. A Benders’ decomposition with linear programming techniques is developed to be able to study large systems. By including dynamic gas constraints into the SCUC, the proposed model accounts for the flexibility and reliability that power systems require from gas systems in the short term. Case studies of different size and complexity are employed to illustrate how the reliability of one system is affected by the reliability of the other. These experiments show how both systems operate in a secure way(by including contingencies) increases operating costs by approximately 9% and also show how these costs can vary by 24% depending on the line pack scheduling.
