Abstract:

The water sector is, currently and for the foreseeable future, challenged by rising levels of uncertainty in demand and availability of water, in a context of aging infrastructure and limited investment. In order to support strategic planning, water companies need a way to assess how their system behaves when faced with a range of changing conditions (climatic trends, asset deterioration, behavioral patterns, etc.) as well as accidents/incidents and/or extreme events (wildcards). In this study, a resilience assessment methodology was demonstrated, with ‘stress tests’ alternative water system configurations (including systems designed with decentralized or distributed philosophies) under a range of scenarios and extreme events. A ‘resilience profile graph’ was developed to quantify the performance of each configuration. The methodology was applied to the real-world urban water system of Oasen, which supplies the eastern part of the Province of South Holland, where the current system configuration and two potential future configurations were tested (one decentralized and one distributed). We show how the concept of resilience, operationalized through this methodology, can assist long term decision making and support strategic infrastructure planning.

Abstract. In drinking water production, river bank filtration has the advantages of dampening peak concentrations of many dissolved components, substantially removing many micropollutants and removing, virtually completely, the pathogens and suspended solids. The production aquifer is not only fed by the river bank infiltrate but also by water percolating through covering layers. In the polder areas, these top layers consist of peat and deposits from river sediments and sea intrusions. This paper discusses the origin and fate of macro components in river bank filtrate, based on extensive full-scale measurements in well fields and treatment systems of the Drinking Water Company Oasen in the Netherlands. First, it clarifies and illustrates redox reactions and the mixing of river bank filtrate and PW as the dominant processes determining the raw water quality for drinking water production. Next, full-scale results are elaborated on to evaluate trickling filtration as an efficient and proven one-step process to remove methane, iron, ammonium and manganese. The interaction of methane and manganese removal with nitrification in these systems is further analyzed. Methane is mostly stripped during trickling filtration and its removal hardly interferes with nitrification. Under specific conditions, microbial manganese removal may play a dominant role.

Abstract:

Context The food security of Tunisia is dependent on utilising all of its resources effectively to feed the population. Rangelands used for grazing are subject to continuous degradation, which reduces the availability of feeds to livestock. In the oasis regions, this constraint is attenuated by the systematic use of various by-products of the palm grove. There is a need to constantly search for alternative feed resources to support ruminant-livestock farming in arid regions and, therefore, the products of desert oases need to be exploited Aims The present work aimed to determine the effect of the use of local resources of oases on feed intake and milk quality of goats. Methods Twenty-four indigenous lactating goats were used to investigate the effect of the substitution of the concentrate feed with alternative feed obtained from oases in Tunisian arid zones. The three study groups in the 60-day trial were as follows: the first group received 0% date waste (WD) + 100% concentrate (CON) + oaten hay; the second group received 50% WD + 30% alfalfa cork (AC) + 20% CON + alfalfa hay; and the third group received 50% WD + 50% AC and no CON + alfalfa hay. Key results Feed intake was higher in Group 2 (1167.10 ± 42.8 g DM/day) than in Groups 3 and 1 (1028.9 ± 68.9 and 856.04 ± 58.9 g DM/day respectively. Average daily milk production did not differ among the groups. Dietary fat and crude protein were not affected by the type of ration. The concentrations of saturated fatty acids were similar in the milk of the three groups. In the three groups studied, the ratio n6:n3 (12.80, 8.80 and 6.77) was higher than the recommended value (<5) for human consumption. Conclusions The use of WD did not affect milk production but it improved the nutritional quality of milk, especially the composition of fatty acid (ratio n6/n3). Implications The use of alternative resources in goat feeding, such as WD and alfalfa cork, can replace the use of market feeds and decrease the costs of animal feed.

Overall Assessment of the Speaker´s Experience of Stuttering (OASESTM; Yaruss & Quesal, 2016) -itsearviointimenetelmä mittaa änkyttävän henkilön kokemuksia änkytyksestä hänen omasta näkökulmastaan. Tutkimuksemme tavoitteena oli arvioida alakouluikäisten OASES-S-, nuorten OASES-T- ja aikuisten OASES-A-itsearviointimenetelmän suomennosten pätevyyttä (validiteettia) ja luotettavuutta (reliabiliteettia). Tutkimuksessa 60 änkyttävää lasta täytti OASES-S:n (60 kysymystä), 31 änkyttävää nuorta OASES-T:n (80 kysymystä) ja 31 änkyttävää aikuista OASES-A:n (100 kysymystä). Mittareiden ulkoinen validiteetti, rakennevaliditeetti ja sisällön validiteetti todettiin hyväksi, joten itsearviointilomakkeet arvioivat pätevästi vastaajien kokemusta änkytyksen vaikutuksesta elämänlaatuun. Eri ikäisille suunnattujen itsearviointilomakkeiden alfakertoimet olivat korkeat (α 0,82–0,95) osoittaen hyvää sisäistä konsistenssia, ja mittaustulosten pysyvyys oli hyvä (r = 0,65– 0,97), lukuun ottamatta OASES-A:n osaa yleiset tiedot. Tutkimus osoitti, että suomennetut OASES-itsearviointilomakkeet erottelevat änkyttävien ihmisten kokemuksia änkytyksen vaikutuksesta heidän elämänlaatuunsa pätevyyden lisäksi luotettavasti. Vaikutuksen luokitukset olisi kuitenkin hyvä muuttaa suomalaisen kliinisen käytänteen mukaisiksi. Lisätutkimuksia tarvitaan kulttuurierojen vaikutuksesta änkytyksen kokemukseen ja sen itsearviointiin arviointimenetelmien sensitiivisyyden parantamiseksi.

Abstract:

ABSTRACTBackground: The assessment of social anxiety in late life has been examined in few studies (e.g. Gretarsdottir et al., 2004; Ciliberti et al., 2011). The present study describes the creation and initial psychometric evaluation of a new, content valid measure of social anxiety for older adults, the Older Adult Social-Evaluative Situations Questionnaire (OASES).Methods: Psychometric properties of the OASES were evaluated in a community dwelling sample of older adults (N = 137; 70.8% female). Convergent validity was established by examining the relation between the OASES and the Liebowitz Social Anxiety Scale (LSAS), Social Phobia and Anxiety Inventory (SPAI), and Beck Anxiety Inventory (BAI). Discriminant validity was established by examining the relation between the OASES and measures of depression (Geriatric Depression Scale, GDS), perceived health status (Short Form Health Survey, SF-12), and demographic variables. The validity analyses of the OASES were based on a smaller sample with n values ranging from 98 to 137 depending on missing data on each questionnaire.Results: Internal consistency, measured by Cronbach's α, for the OASES total score was 0.96. All items on the OASES were endorsed by participants. Convergent validity was demonstrated by medium to large correlations with the SPAI, LSAS, and BAI. Support for discriminant validity was evidenced by small to medium correlations between the OASES and GDS, SF-12, and demographic variables.Conclusions: Evidence in support of convergent and discriminant validity of the OASES is discussed. Although the results from the present study suggest that this measure may assess anxiety in and avoidance of social situations salient to older adults, future studies are needed to further examine the psychometric properties of the OASES and replicate these results in both clinical and more diverse samples of older adults.

Abstract:

Water and soil resources are the key elements required to maintain the stability and sustainable development of oases in inland drylands. This study takes oases in Xinjiang as an example, and reveals the spatial and temporal distribution characteristics of oases across Xinjiang, as well as the dynamic migration and transformation process of oases and the mutual influence of human activities on oasis resources, through a combination of land movement and attitude indicators, use of a gravity model, and Geodetector. The results show that: (1) the area containing the oases in the study has expanded, increasing by 24.0% between 1990 and 2020; (2) both artificial oases (AO) and natural oases (NO) were tilted in a northeast–southwest direction, with the center point of AOs moving slightly to the northeast, and the centripetal force and dispersion degree did not change significantly; the center point of NO moved significantly to the northeast, and the dispersion degree weakened, showing spatial convergence; (3) cultivated land and grassland were the main land types of oasis evolution, and their contribution to evolution was over 70%; and (4) the Geodetector results show that the three main factors driving the evolution of oases were vegetation cover, population density, and GDP. The research results have practical implications for land-use management planning and ecological environmental protection in arid zones.

Abstract:

In this study, several sampling campaigns of terrestrial isopods were carried out in different oases of southern Tunisia as well as in other sites outside the oases. The results made it possible to identify: in the oases, a dozen species belonging to three families Porcellionidae, Armadillidiidae and Armadillidae and in the other sites outside the oasis, only 5 species belonging to the 2 families Porcellionidae and Agnaridae. This difference in species richness could be explained by the different climatic conditions between the two sites studied. Indeed, the majority of the species collected in the oases are characteristic of the wetlands, testifying to the important role of the oases in maintaining this specific diversity of terrestrial isopods.

Abstract:

In Tunisia oases, the Mediterranean fruit fly (medfly) Ceratitis capitata affect heavily fruit production. The efficiency of the mass trapping technique based on the use of Cera Trap® was evaluated in two types of oases in the south of Tunisia against C.capitata. Our results showed that in the traditional oasis (mixed orchard), the medfly moves from one fruit specie to another according to their receptivity periods. The population density of medflies started low and peaked three times (16 Jun, 23 Jun, and 7 July) corresponding to the maturation period of apricot fig and peach fruits. The field study showed that medfly population density and rate of fruit damage were significantly lower in figs than in peaches and apricot. Modern oases have later apricot fruit maturity periods than traditional oases, and their medfly populations peaked at 19 Mai. Ceratrap® reduces 2, 2, and 6 times the population density of Mediterranean fruit fly and the rate of damaged fruits compared to untreated plots. These two parameters were twofold less in modern oases than in traditional oases. These results suggest that the use of traps at the density of 70 per ha is sufficient to protect crops under high population densities of C. capitata characterizing the traditional oases agricultural systems.

Abstract:

Oases settlements are common entities of human agglomerations throughout desert regions. Oases settlements face several environmental challenges such as climate change, which can render them insufferably hot and unlivable within decades. Therefore, this study aims to assess the outdoor thermal comfort variation within three different oases urban fabrics of Tolga Oases Complex in Algeria. The overarching aim is to quantify thermal comfort and guide landscape, and urban designers improve outdoor thermal comfort. The methodology relies on microclimatic measurements and weather datasets (TMY2, TMY3, TMYx), combining observations and numerical simulations. A total of 648 Physiological Equivalent Temperature (PET) values were calculated in three different urban fabrics in Tolga Oases Complex, Algeria. Between 2003 and 2017, a remarkable microclimatic change was found, causing a high and accelerated heat stress level of 76%. The study results inform architects, urban planners and climatologists about climate change effects and urban sprawl impact on the oases lands. Moreover, urban strategies should seek mitigation and adaptation benefiting from the existing green infrastructure of palm groves.

Abstract:

Identifying threats to historical sites is important for formulating preventive measures to reduce their impacts. The oases in Al Ain, United Arab Emirates (UAE), are one of the historical sites and were inscribed as cultural sites in 2011 by UNESCO World Heritage Committee. This study assessed the threats to oases based on the UNESCO-listed factors affecting the outstanding universal value of the World Heritage properties. An Analytic Hierarchy Process (AHP) coupled with remote sensing was used for data collection and analysis. Expert feedback showed that water, urban expansion, soil salinity, palm disease, and the legal framework were major threats. To determine whether urban expansion influences oases preservation, remote sensing images were used to investigate land use and land cover (LULC) around the oases. The LULC change between 1972 and 2022 showed that palm trees, grass, and built-up areas increased by 59%, 76%, and 91%, respectively. The normalized difference vegetation index (NDVI) and normalized difference water index (NDWI) were used to assess stress in the oases. The results indicated that oases have not been impacted by urban expansion since 1972, reflecting the UAE’s commitment to the preservation of oases. The availability of cloud-based and open-access satellite images coupled with AHP is an effective tool for understanding threats. This research aligns with UN SDG 15—“Life on Land”. The concept of this study could be used to assess threats to historical sites. It is recommended that policies for the oases’ preservation be maintained and updated to cater to issues related to population and climate change. Gray water and smart irrigation systems could be assessed as alternatives to minimize water use. Hyperspectral remote sensing is recommended for future studies related to soil salinity and palm diseases.

Abstract:

Abstract With the steep growth of the global population, especially in developing countries, the pressure on the agricultural sector has been increasing. Since the Chinese dairy industry is undergoing rapid development, the demand for adequate high-quality forage is proportionately increasing. Australian oaten hay is regularly exported to China with distinct nutritional benefits, but studies concerning details of the nutritional composition and its influence on the performance of Chinese dairy cows are limited. The controversy related to the harvesting time of oaten hay is another less explored area but critically important factor affecting the nutritional value of forage. This research used a comparative research method to analyze the nutritional composition difference between Australian oaten hay and Chinese oaten hay and the nutrient and yield difference during different harvesting times. Three different forage replacement experiments were reviewed, which were conducted on dry and mid-lactating Chinese Holstein cows and weaned Chinese Holstein calves separately. The corresponding impacts of feeding Australian oaten hay on their production performances were investigated by regression analysis methods. The results of this project can provide a comprehensive understanding of nutritional composition and a systematic overview of the impact of Australian oaten hay on the production performance of Chinese dairy Holstein cows.

Abstract:

Abstract We used data on breeding bird communities of the oases of southern Tunisia to investigate variation in species richness and composition among local communities in relation to spatial configuration of the oasis system and to assess significance of the relationship between oasis size and local richness. Oases could be grouped into three regional systems, namely littoral, saharan, and mountainous oases. We found that at the scale of the entire oasis system, species richness and species composition exhibited significant spatial autocorrelation. That result was consistent with our prediction that the particular spatial organization of oases may have led to regional differences in availability of potential colonizers and that higher species exchange within oasis zones than among oasis zones may have played an important role in shaping local communities. With regard to the species–area relationship, we thus found that a model accounting for spatial covariance was more parsimonious than a standard regression model not incorporating information on the spatial location of oases. Overall, oasis size was a good predictor of species richness, but results were sensitive to spatial scale at which the relationship was examined. Aside from oceanic islands and forest patches, oases may constitute interesting systems to study how regional processes affect local diversity.

Abstract:

Oases regime shifts in the context of integrated water resource management have a significant impact on ecosystem functions and services and affect regional sustainable development and human wellbeing. Taking the Linze Oasis in the middle reaches of the Heihe River as a case study, we evaluated the regime shifts of the oases over the past 30 years from the two perspectives of scale and structure, considering the structural diversity index (H), water savings (Cn), productivity (WP), and other indicators. Furthermore, the driving factors of the socio-hydrological processes and the corresponding effects of the regime stages were discussed. The results indicate that the oases expanded concurrently with the increase in the regional water consumption from 1.09 × 108 m3 to 1.93 × 108 m3. The production of low-water-consumption and high-yield crops was found to be the main cause for the oases structure’s adjustment. The regime shifts in the oases comprised three main stages from 1990 to 2020, based on the interaction of socio-ecological elements. Water management policies promoted the regime shift process, while economic factors determined the long-term shifts. The improvement in water-saving practices driven by economic benefits is an effective way to realize the sustainable development of the Hexi oases.

Abstract:

This article examines the oases that appeared on the inhabited continents of the planet. Historically, in the desert regions formed two main types of irrigated agriculture - small oasis and large oasis. Small oasis farming as a geographical type is developed in the vicinity of small water sources (small streams, streams, springs) in the foothills and in areas where deserts are flooded, groundwater leaks, temporarily adjacent to runoff. The fields of different sizes within the oases made them look like dry sheets, while at the same time showing property and legal inequality.

Abstract:

Friesian cows in early lactation were fed 3.5 or 7.0 kg DM daily of either hammermilled lupin grain, hammermilled oaten grain or whole oaten grain as supplements to a pasture-based diet. Milk production and composition and the amount and composition of whole oaten grain excreted in the faeces were measured. There were no significant differences between treatments in the yields of milk, fat or protein. There was a tendency towards lower milk fat content in milk from cows fed 7.0 kg DM daily of the hammermilled grains. Differences between grain types were not significant for all production parameters except milk protein content. Protein content was significantly (P<0.01) higher in milk from cows fed hammermilled and whole oaten grain compared with that from cows fed lupin grain. Yield of milk fat was significantly (P<0.05) higher and ratio of milk protein to fat significantly (P < 0.05) lower for cows fed 3.5 kg DM of grain than for those fed 7.0 kg DM of grain. There was a significant (P< 0.05) interaction between grain type and grain level for the ratio of protein to fat in the milk. Cows excreted 24% of the whole oaten grain at both levels of grain fed and there were no significant differences in composition of the whole oaten grain fed or excreted in the faeces. There was no benefit to production either from feeding hammermilled lupin grain compared with hammermilled or whole oaten grain or from feeding 7.0 compared with 3.5 kg DM daily of grain to cows grazing pasture.

Abstract:

Purpose: The main purpose of this study is to apply a multidimensional comprehensive instrument to evaluate the overall impact of stuttering (OASES-A) from the perspective of adults who stutter (AWS) who completed one of two intensive stuttering therapies: The La Trobe prolonged speech program and Van Riper’s non avoidance approach. Methods: The OASES-A was applied to evaluate participants’perceptions of their experience of stuttering with the specific aim of compare the changes in the experience of stuttering following two intensive treatments. An essential element in post-treatment evaluation are changes in the speaker’s self reported quality of life. Results: OASES-A group results regarding the La Trobe and Van Riper intensive treatment outcomes show positive changes in stuttering experience for 27 AWS in four sections: 1) general information on stuttering; 2) reactions to stuttering; 3) communication in daily situations; and 4) quality of life. Conclusions: The article represents the first English-language documentation of the Bulgarian results of OASES-A application of previously conducted intensive treatments. OASES-A outcomes show significantly greater overall improvement and changes in the four sections that relate to the experience of stuttering following two intensive treatments. As a research-based instrument for assessment of quality of life in AWS, the OASES-A was easy to administer and analyze. The OASES-A describes in substantial detail the experience and influence that stuttering exerts on quality of life from the client’s perspective. Its application was preferred because it assists speech-language pathology Master’s degree students to recognize the speech needs, abilities, preferences, and interests of AWS.

Abstract:

Human activities and climate change have profound impacts on the ecological environment of oases in Xinjiang, and it is of great significance to explore the spatial and temporal evolution patterns of ecological environment quality in this region for the sustainable development of Xinjiang. The remote sensing ecological index (RSEI) was extracted from the Google Earth Engine (GEE) platform from 2000 to 2020, and the coefficient of variation and Hurst index were used to reveal the spatial and temporal characteristics and stability of the ecological environment quality of the artificial oasis and natural oasis in Xinjiang. The key factors affecting the ecological environment quality are explored through correlation analysis and geoprobes. The results show that the distribution of the ecological environment in Xinjiang oases is high in the north and low in the south, and the overall quality shows a fluctuating downward trend from 0.210 to 0.189. Artificial oases have higher RSEI values, stability, and sustainability than natural oases. The RSEI in the study area was mainly influenced by humidity, followed by greenness and heat, and dryness had the least influence on the RSEI model. Based on the geodetector, the top three highest contributors were found to be precipitation (PRE) (0.83) > relative humidity (RHU) (0.82) > evapotranspiration (ET) (0.57). Climate is the main factor affecting the ecological quality of oases, and the RSEI can be improved by increasing the proportion of artificial oases. The study aims to provide a scientific basis for the sustainable development of oases in arid zones.

Abstract:

The study of the expansion potential of artificial oases based on remote sensing data is of great significance for the rational allocation of water resources and urban planning in arid areas. Based on the spatio-temporal relationship between morphogenetic landform types and the development of artificial oases in Xinjiang, this study explored the development pattern of artificial oases in the past 30 years by using trend analysis and centroid migration analysis, constructing a series of landform–artificial oasis change indices, and investigating the suitability of different landforms for the development of artificial oases based on geomorphological location by adopting a hierarchical clustering method. The following conclusions are drawn: (1) From 1990 to 2020, the area of artificial oases in the whole territory continued to increase, with significant expansion to the south from 2005 to 2010. (2) Six categories of landform types for artificial oasis development were created based on the clustering results. Of these, 7.39% and 6.15% of the area’s geomorphological types belonged to the first and second suitability classes, respectively. (3) The optimal scale for analyzing the suitability of landforms for the development of artificial oases over the past 30 years in the whole area was 8 km, which could explain more than 96% of the changes in the growth of artificial oases. The distribution of landforms of first- and second-class suitability within the 8 km buffer zone of an artificial oasis in the year 2020 was 10.55% and 9.90%, respectively, and landforms of first-class suitability were mainly concentrated in the near plain side of the urban agglomerations located on the northern and southern slopes of the Tianshan Mountains, and the urban agglomerations at the southern edge of Altai Mountains. This study quantified the potential of different geomorphological types for the development of artificial oases and provided a basis for site selection in future artificial oasis planning and urban construction.

Abstract:

The diversity of life sensu lato comprises both biological and cultural diversity, described as “biocultural diversity.” Similar to plant and animal species, cultures and languages are threatened by extinction. Since drylands are pivotal systems for nature and people alike, we use oases in the Sahara Desert as model systems for examining spatial patterns and trends of biocultural diversity. We identify both the underlying drivers of biodiversity and the potential proxies that are fundamental for understanding reciprocal linkages between biological and cultural diversity in oases. Using oases in Algeria as an example we test current indices describing and quantifying biocultural diversity and identify their limitations. Finally, we discuss follow-up research questions to better understand the underlying mechanisms that control the coupling and decoupling of biological and cultural diversity in oases.

Abstract:

As an important agricultural and gathering area in arid inland areas of China, the ecological environments of oasis areas are more sensitive to regional climate change and human activities. This paper investigates the dynamic evolution of the oases in the Tarim River basin (TRB) and quantitatively evaluates the regional ecological security of oases via a remote sensing ecological index (RSEI) and net primary productivity (NPP) through the Carnegie–Ames–Stanford approach (CASA) from 2000 to 2020. The results indicate that the total plain oasis area in the TRB during the study period experienced an increasing trend, with the area expanding by 8.21%. Specifically, the artificial oases (cultivated and industrial land) showed a notable increase, whereas the natural oases (forests and grassland) exhibited an apparent decrease. Among the indictors of oasis change, the Normalised Difference Vegetation Index (NDVI) increased from 0.13 to 0.16, the fraction of vegetation cover (FVC) expanded by 36.79%, and NPP increased by 31.55%. RSEI changes indicated that the eco-environment of the TRB region went from poor grade to general grade; 69% of the region’s eco-environment improved, especially in western mountainous areas, and less than 5% of the regions’ eco-ecological areas were degraded, mainly occurring in the desert-oasis ecotone. Changes in land- use types of oases indicated that human activities had a more significant influence on oases expansion than natural factors. Our results have substantial implications for environment protection and sustainable economic development along the Silk Road Economic Belt.

Abstract:

The impacts of land use/cover changes (LUCCs) on groundwater resources are a global issue. The Shiyang River Basin of China is a typical, ecologically fragile area. Focusing on the Wuwei sub-basin of the central plain, this study analyzed typical remote sensing image data for 17 specific dates since 1970. Before the Comprehensive Treatment Program in 2007, the area of natural oases decreased at a rate of 16.25 km2/year, while the area of farmland expanded at a rate of 13.85 km2/year. The farmland expansion preferentially occurred in low-vegetation-coverage oases, where the groundwater depth increased from 4 to 20 m. The consumption of groundwater increased from 7319.5×104 m3/year to 12,943.2 × 104 m3/year. During the period 2008–2018, the areas of both the natural oases and farmland decreased at rates of 2.57 km2/year and 8.99 km2/year, respectively. The groundwater level rose significantly in the south and west, as well as near the main river channel. Groundwater consumption has been restored to 7270.4 × 104 m3/year. Only 0.12 km2 of every 1.17 km2 of the original natural oases were restored through the natural farmland–natural oases conversion process. Groundwater depth increased significantly with the continuous expansion of farmland. Since the farmland area was effectively controlled, the trend of groundwater-level decline was significantly improved. These findings provide scientific support for the ecological restoration and reconstruction of oases, as well as an efficient and balanced development of river basin water resources.
