چکیده

In a paleo-parasitological analysis of soil samples obtained from V-shaped pits dating to the ancient Baekje period in Korean history, we discovered Ascaris lumbricoides, Trichuris trichiura, and Clonorchis sinensis eggs. In light of the samples' seriously contaminated state, the V-shaped pits might have served as toilets, cesspits, or dung heaps. For a long period of time, researchers scouring archaeological sites in Korea have had difficulties locating such structures. In this context then, the present report is unique because similar kind of the ancient ruins must become an ideal resource for successful sampling in our forthcoming paleoparasitological studies.

Ancient Soil-Transmitted Parasite Eggs Detected from the Sixth Century Three Kingdom Period Silla Tomb

The parasitic infection patterns of the Joseon period have begun to be revealed in a series of paleoparasitological studies. However, parasitism prevailing during or before the Three Kingdom period is still relatively unexplored. In the present study, we therefore conducted parasitological examinations of soil and organic-material sediments precipitated upon human hipbone and sacrum discovered ...

Effects of Nanoscale V-Shaped Pits on GaN-Based Light Emitting Diodes

This paper reviews the formation of nanoscale V-shaped pits on GaN-based light emitting diodes (LEDs) grown by the metal organic chemical vapor deposition (MOCVD) system and studies the effect of V-shaped pits on quantum efficiency. Since V-pits could provide potential barriers around threading dislocations to lessen non-radiative recombinations in such a high defect environment. In our study, ...

An investigation on the effect of shape and size of pits on early establishment of wild pistachio (Pistacia vera L) seedlings in Khajeh Kalat woodland

The aim of this study was to find the most efficient methods for restoring wild pistachio forests through direct seeding and by seedling planting in the woodlands of Khajeh Kalat in Khorasan Razavi. Two planting methods and two pit shapes and four pit sizes were tested. Basin pit sizes were (control, 20, 50, and 100 cm but curve shaped pits were at (control, planting seedlings at ground level),...
