High-resolution mapping of urban Aedes aegypti immature abundance through breeding site detection based on satellite and street view imagery

Identification of Aedes aegypti breeding hotspots is essential for the implementation of targeted vector control strategies and thus the prevention of several mosquito-borne diseases worldwide. Training computer vision models on satellite and street view imagery in the municipality of Rio de Janeiro, we analyzed the correlation between the density of common breeding grounds and Aedes aegypti infestation measured by ovitraps on a monthly basis between 2019 and 2022. Our findings emphasized the significance (p ≤ 0.05) of micro-habitat proxies generated through object detection, allowing to explain high spatial variance in urban abundance of Aedes aegypti immatures. Water tanks, non-mounted car tires, plastic bags, potted plants, and storm drains positively correlated with Aedes aegypti egg and larva counts considering a 1000 m mosquito flight range buffer around 2700 ovitrap locations, while dumpsters, small trash bins, and large trash bins exhibited a negative association. This complementary application of satellite and street view imagery opens the pathway for high-resolution interpolation of entomological surveillance data and has the potential to optimize vector control strategies. Consequently it supports the mitigation of emerging infectious diseases transmitted by Aedes aegypti, such as dengue, chikungunya, and Zika, which cause thousands of deaths each year.

Sister's Visions

Her eyelids were closing. It must have been the stillness in the room that made her realize. The two young elders advanced their slides across the laptop screen and it felt late. She nodded slowly. Then more quickly, attentively, to show that, no, of course she wasn't dozing off. Surely, somewhere in the mission home there was drawer, and in it, a folder with her plane ticket home for the morrow. She was alert.She looked out across the powder blue carpeting, recently vacuumed into long backgammon patterns. What even was carpet, anyway? What was Coca-Cola anymore? Chicken cordon bleu? Automatic ice? This fireside with no fire? Outside and beyond the chain link, in the concrete and cobble streets, someone was burning a small trash pile. Cool air from the river—now coursing along under mostly paved-over canals and culverts—settled over the neighborhood. It was evening and she could smell all this. A dog barked. A bell rang.She thought back to that village on the coast where she had first been sent. A place whose name she would always remember like it had become her own. Washing her clothes in the concrete sink, then pinning them up in the courtyard; nothing brought a storm like hanging clean laundry to dry, a stillness in the air.That's when she had heard them. At first she had thought it was thunder, or the hammer of falling fruits against the zinc roof. But it was the Howlers, moving across the canopy through almendros, mamónes, marañones, and cecropias. Looking up, first she saw just one of them, then all of them at once. An apparition, then a family. There was a mother with a baby on her back, gripping her nape by the fur. She scanned across backlit leaves and caught the mother looking on her, her downward gaze soft, dark, and unhurried. Then the rain.That next morning she had awoken on her back, staring down across the length of her body. No blanket or sheet—it was already hot—just her own feet there at the end of the bed. What forces had sculpted these two duendes, two gifts that at once hold us up and down? Ten glassy faces, knuckles and whorls.Here they were now in these worn grey flats, resting vaguely over the garish blue sea spanning the room. She listened for some sign in this last devotional—world without end—but could suddenly hear nothing. It was a horsehair worm, nightmarishly fine and black as vacuum, that had come writhing out from a vent on the other side of the room. She alone saw this.

Selection of the circumferential speed of the spiked cylinders of cotton cleaners - raw from small trash

This article presents the materials of the theoretical analysis of the working bodies of the machine for cleaning cotton raw materials from small trash. And also the influence of the speed of rotation of the peel cylinder of the cleaner on the separation of small trash from raw cotton was studied. It has been proven that a differential increase in the speed of the spiked will lead to an increase in the cleaning efficiency of the machines. It is recommended that the speed of the first cylinder be 10 m / s, the speed of the second cylinder 11 m / s, the speed of the third cylinder 12 m / s, etc.

Analysis of the Technological Process of Cleaning Raw Cotton from Small Trash

The results of the experimental nature of the vibrations of the grid cotton cleaner

The article provides a new effective scheme and principle of operation of a multifaceted grid of cotton cleaner from small trash. The results of comparative experimental studies of the grid oscillations and the nature of loading depending on the parameters and modes of cotton cleaning are presented. In the experiments performed, the nature of the vibrations was investigated by studying the component vibrations of two grids simultaneously to compare the results. An analysis of the obtained laws of grid vibrations showed that the amplitude of the recommended multifaceted mesh surface on the elastic supports exceeds the amplitude of vibrations of the existing grid 5–7 times and reaches up to (2 ÷ 2.5) × 10−3 m. In this case, the oscillograms are presented for steady-state modes of the work of the cotton cleaner. The results show that an increase in the coefficient of the number of faces of the grid leads to a decrease in the load of the grid to (0.3 ÷ 0.5) N. The parameters of a multifaceted grid of cotton cleaner from small trash are substantiated. Experimental studies have studied the workload and the law of vibrational motion of the grid surface.

Heads or Snails? A Rustic Feast at Hellenistic Philoteria (Tel Bet Yeraḥ, Israel), circa 150 BCE

Abstract The contents of a small trash pit discovered in the recent excavations in Hellenistic Philoteria (Tel Bet Yeraḥ/Khirbet el-Kerak) offer a unique opportunity to study the components of what appears to have been a single festive meal. Extant remains include numerous mammal bones, mollusc shells, and ceramic tableware; they suggest a rustic Mediterranean cuisine, compatible with the presence of Greek settlers in pre-Hasmonean Galilee.

Janitor ergonomics and injuries in the safe workload ergonomic exposure project (SWEEP) study

IntroductionA Minnesota union identified to researchers at the University of Minnesota a concern relevant to a possible relation between their daily workload and outcome of occupational injuries among a population of janitors. ObjectiveTo assess if the ergonomic workload is related to injuries among janitors. MethodsFollowing an initial group discussion among janitors, which identified common and hazardous tasks potentially leading to occupational injuries, a questionnaire was developed, pre-tested, and distributed to the janitors. Questions addressed various exposures, including workload, and comprehensive information regarding injury occurrence over two six-month sequential periods (May 2016–October 2016, November 2016–April 2017). Quantitative ergonomic analyses were performed on a sub-group of janitors (n = 30); these included data collection to identify Borg Perceived Exertion (Borg) and Rapid Entire Body Assessment (REBA) scores. Descriptive, multivariable with bias adjustment analyses were conducted on the resulting data. ResultsEight tasks were found to be common for janitors. All average REBA scores for the tasks were identified in the high-risk category. The task of repeatedly emptying small trash cans (<25lb) was significantly related to injuries. Average Borg scores fell between the very light perceived exertion and somewhat difficult perceived exertion categories. Multivariable regression analyses indicated that age-sex-standardized ergonomic workload, measured by task frequencies and REBA or Borg scores, was positively related to injury occurrence. ConclusionsStandardized ergonomic workload was positively related to injury occurrence. This information serves as a basis for further research and potential intervention efforts.

Fatty acid composition evaluation of edible parts of Eriocheir sinensis in intensive ponds of Gucheng waters.

In Gucheng Lake, Jiangsu Province, China, randomly selected crabs were fed 2 diet types. Crab crude oil methyl ester analysis was performed using gas chromatography-mass spectrometry. Fatty acid compositions in the 3 edible parts of a crab - the hepatopancreas, gonad, and muscle - were analyzed. C16:1 and C18:2 were significantly higher in most commercial pellet feed-feeding crabs than in small trash fish-feeding crabs, while the opposite was observed for eicosapentaenoic and docosahexaenoic acids. Phytanic acid reached 1.93% in the hepatopancreas of small trash fish-feeding crabs. Furan fatty-acid-DiMe (11,5) contents in the testes of small trash fish-feeding crabs was 1.49%. These values were higher in male crabs than in female crabs. According to a standard ratio of 1:1:1 which meaning the saturated fathy acid (SFA), monounsaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) were 33.33 each, fatty acid structure analysis of crab edible parts showed that SFA:MUFA:PUFA of crab edible parts was 2.3-4.1:2.9-5.0:1.3-4.8. The highest muscle score was 29.53 in male trash fish-feeding crabs, and the lowest hepatopancreas score was -40.81 in female commercial pellet feed-feeding crabs. The n-6/n-3 ratio was 0.36-2.48. Muscle ratio was the lowest in female commercial pellet feed-feeding crabs. Thus, small trash fish-feeding and commercial pellet feed-feeding crabs are healthy foods. Overall, for consumption, the males of small trash fish-feeding crabs were better than the females, the muscle was better than the gonads and hepatopancreas, and the testis was better than the ovary.

1A1-H05 水中ロボット開発のための簡易漏水検知システム(水中ロボット・メカトロニクス(1))

In the case of the development of underwater robots, loss is greater due to leaked water. Therefore, it is necessary to pay sufficient attention to the design of the pressure tight case. However, it may cause water leakage by the operation, for example, water leak due to slight cracking of the cable and a small trash at the time of maintenance work of the pressure tight case. Hence, we propose "simple leaked water detection system". This system uses control devices which are generally used for underwater robot. This paper describes about this system and the basic experiments.

The Android and the Animal

Pixar's animated featurewall-E(2008) revolves around a sentient robot, a small trash compactor who faith fully continues his programmed duties seven hundred years into the future, after humans have long abandoned their polluted home planet. Landscaped into skyscrapers of compacted waste, Earth no longer seems to harbor any organic life other than a cockroach, Wall-E's only and constant friend. Similarly, in Mamoru Oshii'sGhost in the Shell 2: Innocence(2004;), sequel to the groundbreaking firstGhost in the Shellanime, the love of the cyborg police officer Batou for his vanished colleague Motoko Kusanagi is surpassed only by the care and affection he displays for his pet basset hound. These films are two recent examples of works of science fiction in which the emergence of new kinds of humanoid consciousness in robots, cyborgs, or biotechnologically produced humans is accompanied by a renewed attention to animals. Why? In what ways does the presence of wild, domestic, genetically modified, or mechanical animals reshape the concerns about the human subject that are most centrally articulated, in many of these works, through technologically produced and reproduced human minds and bodies?

유비쿼터스 홈 메스클린업 로봇의 구현에 관한 연구

In this paper, Ubiquitous Home Mess-Cleanup Robot(UHMR), which has a practical function of the automatic mess-cleanup, is developed. The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which was the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash but has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. It needs functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of tile self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulate,, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. We use the RFID system to solve the problems in this paper and propose the reading algorithm of RFID tags installed in indoor objects and environments. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It needs to also has the entertainment functions for the good communication between the human and UHMR. Finally, the good performance of the designed UHMR is confirmed through the results of the mess clean-up and arrangement.

INFLUENCE OF COTTON VARIETIES AND GIN MACHINERY ON TRASH PARTICLES

Small trash particles create serious operational problems for textile mills during spinning. Samples of cotton fromfive studies involving numerous gin machinery sequences, moisture levels, cotton varieties, and two harvesting methods(spindle and stripper) were evaluated before and after gin processing. The foreign matter before any cleaning, after cleaningof the seed cotton, and ginning and lint cleaning was measured. The particle sizes of the foreign matter in the ginned andcleaned lint were evaluated with an Advanced Fiber Information System (AFIS). The more aggressive seed cotton cleaningand lint cleaning machinery treatments produced the lowest levels of all types of trash particles including the particles 50 to500 microns and 500 to 1000 microns, which include the sizes of concern to the textile industry. Very large differences alsooccurred as a result of different varieties, harvesting methods, and field locations.

Trade Dress Protection for Computer User Interface "Look and Feel"

An employee on way back to his office glances at illuminated screen of a nearby computer. He sees small trash can in lower right corner; graphics of labeled folders, documents, and applications in center; and a strip of words across top of screen. He immediately assumes that computer is an Apple Macintosh. A spreadsheet programmer determines that an application program requires her to use a backslash to access multi-layered command menus and to strike first letter of layered menu items in sequence in order to execute any series of commands. She knows software must be Lotus 1-2-3. Apple and Lotus realize that computer users rely on these elements to identify computer programs.' Accordingly, both companies have invested time and money to build consumer recognition of their programs and have sought legal protection for their user interfaces.2 A personal computer's user interface is the means by which software and user interact.' Audio-visual displays are most obvious means of communicating with user, but user interface also includes other elements of computer system such as keyboard and printer.4 The look and feel of

Mechanically Removing Southwestern Corn Borer Pupae from Plastic Rearing Cups12

A machine was constructed for mechanically removing pupae of Diatraea grandiosella (Dyar) from 30-ml clear plastic rearing cups containing diet medium. The cups are split in half, and the parts and their contents are conveyed to a separator system where the pupae and small trash are remove from the larger trash. This machine is 96% effective in removing pupae. It operates at a speed of 1,400 cups/h, whereas the average worker can harvest pupae from ca. 400 cups/h by hand. Adult emergence from pupae removed with this machine was equal to that from pupae removed by hand. This machine was ca. 90% efficient for the fall armyworm, Spodoptera frugiperda (J. E. Smith), and the corn earworm, Heliothis zea (Boddie), pupae, as Well.

The Effects of Cleaning in the Opening Room and at the Card on Rotor Residue for Open-End Machines

The effect of cleaning in the opening room and at the card on rotor trash accumulation was in vestigated. Studies were done for a commercial machine without a trash cleaner, for one with a trash cleaner, and for a small-sample, four-rotor Spintester with a trash cleaner that could be closed. For the machine without the cleaner, extra cleaning in the opening room slightly reduced rotor trash accumulation. However, good carding conditions greatly reduced the trash accumulation. For the machine with the cleaner, extra opening-room cleaning had no effect, and carding had only a slight effect on rotor trash accumulation. Feed slivers that contained relatively large trash particles, primarily organic material, yielded greater rotor trash accumulation than those that contained rela tively small trash particles. The increase was large for the machine without a trash cleaner, and small for the machine with an efficient trash cleaner, rotor combination.
