This paper presents the first results of the research agreement signed by the Federico II University and CDP Immobiliare concerning reusing  and recycling construction waste in the urban regeneration project. The research is aimed to develop a technical protocol for the ex-ante evaluation of the demolition operations, with a special focus on the criteria for picking the material samples to undergo chemical-physical analysis. The article is focused on the demolition process, implementing a BIM-based filing of the building system and aimed at a preliminary understanding of the material quantity, the material consistency and the state of conservation of the elements to be demolished. A tentative pre-characterisation, and an inventory of any contaminants present in the materials are also provided. In the form of discussion, further implications related the building characterisation and the planning of material flows with the reuse and recycle supply chains are provided as well.

New Evidence

This paper tries to explain the first results obtained on trench 102, located on the southwestern area of the ancient harbour of Berenike. Chronologically the trench runs from the Late Hellenistic to Roman Period, showing different uses of this area during Antiquity. Some of the data recovered are quite interesting in order to understand the evolution of this scarcely known area of Berenike’s harbor. The identification of a metallurgical furnace related to the Late Hellenistic Period is especially remarkable, as it provides some insights about the structure of this zone under the last Ptolemaic rulers. So, the main objective of the paper is to offer new data about the productive structure of this site during the Ptolemaic period with special focus on the metallurgical production.

Abstract In this work, a slightly unetched gate hard mask failure was analyzed by nano probing. Although unetched hard mask failures are commonly detected from the cross sectional view with FIB or FIB-TEM and planar view with the voltage contrast, in this case of the very slightly unetched hard mask, it was difficult to find the defects within the failed area by physical analysis methods. FIB is useful due to its function of milling and checking from the one region to another region within the suspected area, but the defect, located under contact was very tiny. So, it could not be detected in the tilted-view of the FIB. However, the state of the failure could be understood from the electrical analysis using a nano probe due to its ability to probe contact nodes across the fail area. Among the transistors in the fail area, one transistor’s characteristics showed higher leakage current and lower ON current than expected. After physical analysis, slightly remained hard mask was detected by TEM. Chemical processing was followed to determine the gate electrode (WSi2) connection to tungsten contact. It was also proven that when gate is floated, more leakage current flows compared to the state that the zero voltage is applied to the gate. This was not verified by circuit simulation due to the floating nodes.

A key theme in urban governance research is how neoliberalism reshapes the state–society relationship. Our study on Guangzhou, where urban regeneration through massive redevelopment of “villages-in-the-city” uncovered interactions between the state, market, and community in local governance, contributes to this debate. Based on intensive field research to analyze three projects, we find that what really controls neoliberal growth in China is not simply the authoritarian tradition of the socialist state but also the power of the indigenous village communities. Our findings suggest that state intervention for community building is vital for rebalancing power relations between the state, market, and community.

Key Questions

This special focus section analyses state–diaspora relationships with a focus on the case of Eritrea, a paradigmatic example, as we show in this introduction, to elaborate on the following key questions: What determines loyalty between diaspora and the state? How can we understand the dynamics of co-optation, loyalty, and resistance that characterise many diaspora–state relationships? What is the role of historical events and memory in building alliances as well as divides among different generations and different groups in the diaspora? How do diaspora citizens interpret and enact their citizenship in everyday practices of engagement? By engaging with both citizenship and diaspora studies, this introduction shows the significance of analysing these questions through the lens of “transnational lived citizenship.” This concept enables a look at the intersections between formal aspects of citizenship as well as the emotional and practical aspects related to feelings of belonging, transnational attitudes, and circulation of material cultures.

Nutritional Status Of Children

SummaryThis study aimed to identify the determinants of nutritional status of children in India with a special focus on dietary diversity at the state level. Household-level consumption data from three rounds of the Consumer Expenditure Survey of the National Sample Survey Organization (1993–2012) were used. Information on the nutritional status of children was taken from the National Family Health Survey (2005–06). Dietary diversity indices were constructed at the state level to examine diversity in quantity of food consumed and food expenditure. Multilevel regression analysis was applied to examine the association of state-level dietary diversity and other socioeconomic factors with the nutritional status of children. It was observed that significant variation in childhood stunting, wasting and underweight could be explained by community- and state-level factors. The results indicate that dietary diversity has increased in India over time, and that dietary diversity at the state level is significantly associated with the nutritional status of children. Moreover, percentage of households with a regular salaried income in a state, percentage of educated mothers and mothers receiving antenatal care in a community are important factors for improving the nutritional status of children. Diversity in complementary child feeding is another significant determinant of nutritional status of children. The study thus concludes that increasing dietary diversity at the state level is an effective measure to reduce childhood malnutrition in India.

Seed Management

Seed management carried out by The State Forests National Forest Holding is an integral part of rational forest management. Seed collection takes place mainly from stands belonging to first category of forest reproductive material, which is the largest seed base in Poland. In smaller amount, seeds are collected in selective objects of highest forest reproductive material category (selected seed stands, seed orchards). The previous estimation methods of seed crop were based on visual assessment of cones in the stands for their harvest. Following the rules of FRM transfer is additional difficulty of rational seed management which limits the possibility of the use of planting material in Poland. <br><br> Statements concerning forecast of seed crop and monitoring of seed quality is based on annual reports from the State Forest Service. Forest Research Institute is responsible for preparing and publishing above-mentioned statements. A small extent of its automatization and optimization is a large disadvantage of this procedure. In order to make this process more effective web-based GIS application was designed. Its main performance will give a possibility to upload present-day information on seed efficiency, their spatial pattern and availability. Currently this system is under preparation. <br><br> As a result, the project team will get a possibility to increase participation of seed material collected from selected seed base and to share good practices on this issue in more efficient way. In the future this will make it possible to obtain greater genetic gain of selection strategy. <br><br> Additionally, first results presented in literature showed possible use of unmanned aerial system/vehicle (UAS/V) for supporting of seed crop forecast procedure.

The Impact

This study assessed the impact produced by a wildfire and an infectious outbreak led by an oomycete pseudofungi, both occurred in 2015, on the state of Araucaria-Lenga forests of the China Muerta Reserve, placed in the southern Andes of Chile. To do this, a greenness vegetation spectral index was calculated over a multitemporal set of Landsat-8 images, acquired biannually on near-anniversary dates, which was subject to subtractions between ex-ante (2013) and ex-post dates (2015, 2017, 2019). Results show the magnitude and temporal progression of both disturbances, highlighting the celerity and aggressiveness of the wildfire. Although the affected vegetation land covers currently show values close to the recovery of the primal biomass, the inclusion of field-based data to deepen the possible composition and structure variations of these forests is needed.
