Abstract
This paper is a part of a long-term study on the Noctuidae fauna of Kerman province. Here we report the newly identified species, which were collected mostly in the South of this province during the years 2015 and 2016. Totally, here we report 30 Noctuidae taxa from 13 genera and six subfamilies namely: Acronictinae (five taxa), Amphipyrinae (three taxa), Heliothinae (two taxa), Condicinae (two taxa), Bryophilinae (six taxa) and Noctuinae (12 taxa). Among these reports there are 12 new provincial records from Kerman. Amphipyra kitti Gaal-Haszler, Lödl, Ronkay, Ronkay & Varga, is recorded here as a new species for the fauna of Iran. Material examined is listed together with provincial distribution for each taxon. Wing pattern and male and female genitalia structures of A. kitti illustrated here. The female genitalia of this species describe here for the first time. According to this data, we concluded that despite the vast area of Kerman province, its fauna has been less explored compared to some of its neighboring provinces. We suggest to explore especially higher altitudes of this province.

Abstract
Aims Due to increase of demand for industrial and agricultural products, many tropical regions of Iran have experienced landscape changes. The present study aims to detect the land use/land cover (LULC) using some pixel/object-based approaches.
Method This research was conducted in Jiroft area using some pixel-based and object-based image analysing methods (PBIA and OBIA respectively). To this end, at the first phase, the LULC maps were extracted using PBIA for September, 2020. The PBIA are including as Mahalanobis distance (MD), maximum likelihood (ML), neural network (NN), support vector machine (SVM). At the second phase, the LULC was produced using OBIA approach, encompassing the multi-resolution method and decision tree (DT) technique, for segmentation and classification respectively. Using a hybrid methodology, the high-resolution images of Worldview-2 were segmented. The segmented objects were later combined with the 7-month time series of NDVI, to find the necessary thresholds for DT.
Findings Results of the LULC maps demonstrated that the kappa coefficient and overall accuracy for ISODATA, MD, ML, NN, and SVM methods were calculated to be (51%, 66%), (81%, 86%), (88%, 91%), (90%, 93%) and (88% and 92%), respectively. The outcomes of the second phase for mapping the LULC showed the OBIA achieved a high overall accuracy of about 96%.
Conclusion among the PBIA techniques and regarding both accuracy and execution time, the ML was the best. Although both PBIA and OBIA approaches are applicable in mapping LULC, the OBIA significantly outperformed the PBIA classifiers by higher overall accuracy and Kappa statistics

Abstract
The fifth season of archeological excavation of Konar Sandal Mound Hill in Jiroft (located in southeast of Iran) in 2006 was characterized by discovery of a clay monument on the wall of one of the architectural spaces there. With dimensions of 110 × 95 cm and 18cm thickness, the monument is regarded as the unique and oldest clay relief ever discovered (third millennium BC). On the one hand, historical and artistic values of the unique monument and its location in the site and environmental and human threats causing serious damages to it on the other hand, has made its documentation ever more necessary. The study of constituting materials and building techniques of the monument was done through macroscopic (field and visual study) and microscopic (optical and electron) methods as well as chemical analysis of elements and compounds on the clay foundation and its color layers (FT-IR, XRF, XRD, and SEM-EDS). The results suggest that the clay monument was built in two parts, namely the built-on torso and lower torso (skirt) which was carved out on a cob wall. Then, a delicate finish layer made of clay was put on the colored layer. The finish layer was made by using mineral pigments such as limonite (yellow) for covering the body (i.e. arms, chest and waist scarf), and Ochre hematite (red) and carbon (black) for ornament of embossed skirt. The used clay soil is of montmorillonite type which reacts, expands and contracts significantly due to humidity variation.
