Research on the design of small interior space

In such a high population density society as China, especially in developed cities, the real estate market needs a concept of micro-housing. Working people in big cities like Beijing and Shanghai spend very little time at home while working and socializing outside the home every day. High-density population cities need to meet the living needs of as many people as possible in a limited area. If we can solve this problem the demand for houses will decrease and prices will fall. And tiny buildings can also reduce greenhouse gas emissions. (Statistics show that residential, commercial, and industrial buildings account for 40 percent of greenhouse gas emissions.) The ecological benefits of micro buildings extend beyond the house itself. Micro buildings not only increase the density of housing, so that more people have a home, but also shorten the time of transportation. After consulting a large number of literatures, this study hopes to summarize the existing literatures and find the best way for micro buildings to meet the needs of more people in high-density population cities. In this study, conclude some interior design methods or techniques to find out how to improve the quality of small space design. We search and review information in three different fields: indoor thermal comfort, human-based furniture, and interior lighting design. The paper presents some techniques including thermal control equipment and a day-light prediction system. Different human-based furniture is divided into various types, we analyse their advantages and disadvantages, leading to the small interior space to find how can they be used to improve human’s feeling. We discuss the possibility that designers enhance people’s life in a big city by using indoor designing ways.

Radio-transmitters gnawed by edible dormice Glis glis in populations of different density

In a radio-tracking study of the edible dormouse Glis glis in Poland, 20 transmitters out of 125 used showed traces of gnawing, presumably by other dormice. All gnawed devices were found in a high-density population (8.0–9.5 individuals/ha) and none in low-density populations (2.5–5.5 individuals/ha). Sex, reproductive activity and season had no perceived impact on the damage done to the transmitters.

Detection of SARS-CoV-2 using high-throughput PCR

During an epidemic identification of infected individuals, quarantining them, and thereby protecting healthy individuals from infection will not only help to flatten the curve but will also help medical professional to treat the epidemic efficiently. Countries with high-density population require sensitive and accurate screening method, which could be done without a sophisticated laboratory, broadens the scope of control and surveillance. High-throughput screening method without expensive instrumentation is the desirable. For the SARS-CoV-2 pandemic qRTPCR emerges as a gold standard for identification of infection, however, infrastructure required for this assay is at high-demand and not abundant. Therefore, we proposed a high-throughput PCR based sensitive method which provides an opportunity to facilitate detection of virus without sophisticated diagnostic infrastructure

Quantifying the interactions between koalas in a high-density population during the breeding period

A species’ social structure influences its patterns of gene flow and disease transmission. Knowledge of social structure therefore is critical for understanding conservation challenges and informing management strategies. We examined the social structure of 33 free-ranging koalas (Phascolarctos cinereus) in a high-density population (6.7 koalas per hectare) during the early and peak phase of the breeding period (August–December) at Cape Otway, Victoria. We used GPS and proximity loggers to quantify koala space use and interactions, and direct observations to determine behaviours associated with interactions. Our proximity loggers recorded 661 interactions (64% male–female, 28% male–male and 8% female–female). A peak in male–male interactions at the onset of the breeding period suggested that males may physically compete for mates at this time. Male–female interactions increased from the onset of the breeding period, and were mostly of short duration (median duration 5.5 min). From field observations of interactions, and the absence of pouch young in December, many of these interactions may have been unsuccessful copulation attempts. Space use and social network analyses revealed that most males had strong links (total interaction duration >30 min) with only one or two females, despite their spatial overlap and interactions with multiple females. Body mass did not influence a male’s mating success in terms of number of female mates. Our results contrast with those of a lower-density population in central eastern Queensland, suggesting that some aspects of koala social structure may be plastic relative to population density.
