Archaeological researches at Gunung Wingko Site, Kecamatan Sanden, Bantul, had been conducted formore than 40 years ago. Nevertheless, the results of observations, interviews, Focus Group Discussions(FGD), and archaeological exhibition on Sanden Fair 2018 indicate that the existence and the culturalsignifcance of the site had only been known by certain communities. Local people unawareness of theexistence and the cultural signifcance of the site had so far caused site damage. Terefore, a number ofaction plans have been suggested during the FGD that involved the local people and some institutionsrelevant to the case of Gunung Wingko, and have to be done as soon as possible to prevent the sitefrom further damage. Te plans comprise dissemination of the site values, the establishment of thesite as cultural heritage (Cagar Budaya), site management, and the development of a site informationcenter. Tis center could be integrated with other tourist destinations which have been establishedaround the site. In this case, local people should be involved in preparing material displayed in theGunung Wingko Site Information Center.

The Ramesses III (KV 11) Publication and Conservation Project is currently developing a site management, conservation and publication strategy for the severely damaged tomb of pharaoh Ramesses III in order to prevent further deterioration and to preserve this cultural heritage site for future generations. Along with first urgent measures of conservation, a geo-archaeological survey of KV 11 and its surroundings, as well as a geomatic and photogrammetric survey of the tomb itself, were carried out. The detailed recording of the current state of the architecture and wall decoration allowed for further reconstruction of scenes and texts. Moreover, an archaeological sondage in the burial chamber revealed additional information about the ooding and sedimentation processes. A field school with students of Luxor University offered training in digital recording methods and epigraphy, geo-archaeological survey and mapping methodologies, and conservation treatment and assessment. The following article outlines preliminary results in the fields of geology, conservation, recording, reconstruction, and excavation.

ABSTRACT We report observations with the Atacama Large Millimetre Array (ALMA) of six submillimetre galaxies (SMGs) within 3 arcmin of the Distant Red Core (DRC) at z = 4.0, a site of intense cluster-scale star formation, first reported by Oteo et al. We find new members of DRC in three SMG fields; in two fields, the SMGs are shown to lie along the line of sight towards DRC; one SMG is spurious. Although at first sight this rate of association is consistent with earlier predictions, associations with the bright SMGs are rarer than expected, which suggests caution when interpreting continuum overdensities. We consider the implications of all 14 confirmed DRC components passing simultaneously through an active phase of star formation. In the simplest explanation, we see only the tip of the iceberg in terms of star formation and gas available for future star formation, consistent with our remarkable finding that the majority of newly confirmed DRC galaxies are not the brightest continuum emitters in their immediate vicinity. Thus, while ALMA continuum follow-up of SMGs identifies the brightest continuum emitters in each field, it does not necessarily reveal all the gas-rich galaxies. To hunt effectively for protocluster members requires wide and deep spectral-line imaging to uncover any relatively continuum-faint galaxies that are rich in atomic or molecular gas. Searching with short-baseline arrays or single-dish facilities, the true scale of the underlying gas reservoirs may be revealed.

Oxide Support

Supported rare earth double perovskite (La2MnNiO6) oxide catalysts were prepared by incipient wet impregnation method for methane catalytic combustion, and effects of the support (Al2O3, ZrO2 and MgO) were investigated. The loaded catalysts were characterized by means of XRD, TPR, SEM techniques and their catalytic activities were tested by complete methane oxidation. Depending on the different oxide carrier (e.g. Al2O3, MgO and ZrO2), catalysts have different catalytic properties, because the interaction of metal oxide-support will affect both redox property and dispersity of the active phase. The results on catalysts have shown that the dispersion on Al2O3 and MgO supports had an effect to enhance the catalytic performances of the catalysts that had been treated at 1100 oC. The activity of ZrO2 supported catalyst significantly decreases when calcination temperature at is 1100 oC. The dispersity of the active phase and the nature of the oxide carrier played an important role in the catalytic performance.
