Rainwater harvesting (RWH) for domestic uses is widely regarded as an economic and ecological solution in water conservation and storm management programs. This paper aims at evaluating long-term trends in 20-day cumulative rainfall periods per year in Poland, for assessing its impact on the design and operation conditions for RWH systems and resource availability. The time-series employed corresponds to a set of 50-year long time-series of rainfall (from 1970 to 2019) recorded at 19 synoptic meteorological stations scattered across Poland, one of the European countries with the lowest water availability index. The methods employed for assessing trends were the Mann–Kendall test (M–K) and the Sen’s slope estimator. Most of the datasets exhibit stationary behaviour during the 50-year long period, however, statistically significant downward trends were detected for precipitations in Wrocław and Opole. The findings of this study are valuable assets for integrated water management and sustainable planning in Poland.

An increasing scarcity of water, as well as rapid global climate change, requires more effective water conservation alternatives. One promising alternative is rainwater harvesting (RWH). Nevertheless, the evaluation of RWH potential together with the selection of appropriate sites for RWH structures is significantly difficult for the water managers. This study deals with this difficulty by identifying RWH potential areas and sites for RWH structures utilizing geospatial and multi-criteria decision analysis (MCDA) techniques. The conventional data and remote sensing data were employed to set up needed thematic layers using ArcGIS software. The soil conservation service curve number (SCS-CN) method was used to determine surface runoff, centered on which yearly runoff potential map was produced in the ArcGIS environment. Thematic layers such as drainage density, slope, land use/cover, and runoff were allotted appropriate weights to produced RWH potential areas and zones appropriate for RWH structures maps of the study location. Results analysis revealed that the outcomes of the spatial allocation of yearly surface runoff depth ranging from 83 to 295 mm. Moreover, RWH potential areas results showed that the study areas can be categorized into three RWH potential areas: (a) low suitability, (b) medium suitability, and (c) high suitability. Nearly 40% of the watershed zone falls within medium and high suitability RWH potential areas. It is deduced that the integrated MCDA and geospatial techniques provide a valuable and formidable resource for the strategizing of RWH within the study zones.

Traditional ritual is a kind of expression of art and culture as well as a form of human appreciation of nature, gained through long term and perpetual processes. Traditional ritual thus can thus be regarded as traditional wisdom. Kawin Cai is one of the traditional rituals in Kuningan society derived from inter religious views. Through this ritual we could tell that the people respect their natural environment for sustainable living. Nonetheless, most of the symbolic practices in the ritual are no longer understood by the people, so that anthropological approach is needed to interpret them.

The Internet, particularly through the application of World Wide Web (WWW) technology, has proved to be a very attractive medium for publishing. However, the difficulties of finding appropriate information online and then of ensuring its long term accessibility have created problems for libraries. Practices that work for books and other printed materials do not always translate directly to online materials. The National Library of Australia's PANDORA project has been set up to develop policies and procedures for ensuring long term access to significant Australian publications which are accessible only in an online environment, and to establish and maintain a permanent archive ofthat material.

Congenital central hypoventilation syndrome is a disorder predisposed by a paired-like homebox PHOX2B gene. A mutation in the PHOX2B gene is a requisite when diagnosing congenital central hypoventilation syndrome. This mutation is identified in 93–100% of diagnosed patients. The mutation regarding this disorder affects the sensors, the central controller, and the integration of the signals within the central nervous system. This, inter alia, leads to insufficient ventilation and a decrease in PaO2, as well as an increase in PaCO2. Affected children are at risk during and after the neonatal period. They suffer from hypoventilation periods which may be present whilst sleeping only or in more severe cases when both asleep and awake. It is important for clinicians to perform an early diagnosis of congenital central hypoventilation in order to prevent the deleterious effects of hypoxaemia, hypercapnia, and acidosis on the neurocognitive and cardiovascular functions. Patients need long-term management and appropriate ventilatory support for improving the qualities of their lives. This paper provides a detailed review of congenital central hypoventilation syndrome, a congenital disorder that is genetic in origin. We describe the genetic basis, the wider clinical picture, and those challenges during the diagnosis and management of patients with this condition.

In addition to the dry (D) and rainy (R) seasons, a combination of the two i.e., rainy-dry (RD) and dry-rainy (DR), can also be observed in one year. The effects of the dry (D) and rainy (R) on soil are known, hence we hypothesized that the effects of the rainy-dry (RD) and dry-rainy (DR) periods on soil may differ from the former assessments. The aim of the study is to investigate the effect of six tillage treatments (ploughing—P, disk tillage—DT, loosening—L, tine tillage (a deeper—T and a shallower—ST) and no-till—NT) on earthworm abundance and crumb ratio during a long-term research (16 years) on Chernozems. The results related to the four year-groups (D, R, RD, and DR) with different residue cover. Seven degrees of cover ratio (between 12.5% and 62.5%) were selected on stubbles. Higher cover ratio (≥52.5%) improved water conservation, increased earthworm abundance (31 and 41 ind m–2) and crumb (78 and 82%) ratio (p < 0.01). R year came first in the rank of water content and earthworm abundance and DR proved to be more favorable for crumb formation. Considering the rank of soil tillage treatments, ST takes first place in evaluation of soil water content (SWC) and crumb ratio, and NT for earthworm abundance.

<p>Clean water crisis that occurred in Bandung is caused by land conversion in North Bandung area which is a recharge area into commercial buildings. This increases runoff rate from 40% to 70% that can lead can lead to flooding and reduced groundwater availability. Therefore, it is necessary to save water by implementing water conservation. Considering those problems, this study aims to apply the concept of water conservation in X Apartment building that is located in the North Bandung Region by referring to Mayor Regulation of Bandung in 2016. Water conservation efforts that will be applied are wastewater reuse into water recycle, rainwater harvesting, infiltration well construction and placing water meters. The application of water conservation concept considers two conditions, namely in rainy season and dry season. Total need for clean water can be saved by 45,8% in dry season, while in rainy season clean water can be saved by 31,74%.</p>

The Art Institute of Chicago (AIC) and George Eastman House International Museum of Photography and Film (GEH) have acquired substantial collections of László Moholy-Nagy's work, spanning his entire career. Using four photograms by Moholy-Nagy, two from each institution, as representative examples, this thesis examines how the AIC and GEH have dealt with his work through an examination of the acquisition, exhibition, publication, preservation, and conservation of his photographs. The unique nature of Moholy-Nagy's photograms, coupled with the myriad experimental techniques he employed in their production, has necessitated that the AIC and GEH establish policies and procedures for the care and long-term preservation of photographic objects of this nature, through the development and implementation of exhibition and loan standards as well as highly monitored storage conditions. This thesis includes an overview of the museums, a detailed analysis of each photogram, and a discussion of the collections management concerns that these objects raise.
