Perbandingan Kualitas Pot Hitam dan Softpot Terhadap Pertumbuhan Vegetatif Anggrek Dendrobium sonia ersakul

The aim of this research is to compare the quality of black pots and soft pots on the vegetative growth of the Dendrobium sonia ersakul orchid. The method used was perfect randomization with one treatment, namely black pot and soft pot. Data analysis used a two-way t-test at the 5% level. The results of the research show that using different types of pots can make a real difference to the parameters of plant height, length of shoots and number of new roots, but does not make a real difference to root length. The difference in the quality of the two pots is influenced by the level of water supply to the plant, plant drainage, and the level of oxygen absorption in the roots.

Road Accident Severity Prediction using Machine Learning

Road accidents have become a major concern globally, causing a significant number of fatalities and injuries every year. The aim of this project is to predict road accidents severity using machine learning techniques, in order to reduce their occurrence and mitigate the associated risks. The project uses data collected from various sources such as accident reports, weather conditions, and road infrastructure to train and evaluate various supervised learning algorithms and predict the accident severity. Four algorithms were compared, including Decision Tree, Naive Bayes, Random forest . Most probably occurring road accident locations are identified and that particular region is indicated as black pot. The proposed method can be used to provide real-time risk information to road users, helping them to make informed decisions and avoid potential accidents. The project highlights the importance of using machine learning techniques in road safety analysis, providing a foundation for further research in this field

“Carrying the black pot”: Food safety and risk in China's reactive regulatory state

AbstractThis paper explores the struggles of China's party‐state to address chronic food safety problems by adopting international best practices of risk‐based regulation. Despite formally adopting risk‐based approaches for targeting inspections and enforcement in 2002, implementation has been halting and uneven, as we show in the first analysis of risk‐based regulation beyond its OECD heartlands. Drawing on policy document analysis and 36 key informant interviews with food business operators and government officials working on food safety regulation at every level of the state, we identify contradictions between official commitments to risk‐based inspection and top‐down demands for zero tolerance and strict accountability, which leave local inspectors preoccupied with avoiding blame more than reducing safety risks. Our analysis advances recent scholarship on regulatory states of the global South by highlighting how risk‐based ideas, instruments, and practices are refracted through the distinctive norms and style of China's reactive regulatory state.

SEGMENTAÇÃO E CONTAGEM AUTOMÁTICA DE OVOS DO AEDES AEGYPTI EM PALHETAS DE OVITRAMPA BASEADA EM APRENDIZADO PROFUNDO

Dengue is an endemic disease, being one of the main health problems worldwide. The ovitraps simulate a per- fect environment for breeding Aedes aegypti. It consists of a black pot filled with water, which remains stationary, attracting the mosquito. A wooden straw is inserted into it, which makes easier for the female Aedes aegypti to lay eggs. However, the major disadvantage of this technique is the counting of mosquito eggs that is performed manually, one by one, using a magnifying glass, making the count- ing process slow. Thus, this work presents a computational methodology to segment and counting eggs in ovitrap straws that aims to help specialists in this counting. For the de- velopment of this work, we carried out tests using different color spaces and U-net architectures with different numbers of layers and filters. Then, we searched for the best pa- rameters of a post processing step based on mathematical morphology. The results achieved were promising with an accuracy of 98.65% in the segmentation of eggs and a mean square error of 4.47 in the counting of eggs.

The Identity That Doesn’t Deny Difference: A Non-dualist Argument

Brahmānanda Sarasvatī has written an elaborate comment on the following inference cited in Advaitasiddhi: attribute etc. are identical to and different from attributee etc. since they are co-referential. There he wants to prove that every significant case of attribution (such as ‘x [is] y’) is a case of identity that coexists with a difference between two demarcators (upalakṣaṇa). The identity that coexists with difference is called ‘equality’ (tādātmya). This paper will argue that in each case of equality, the realist ontology chooses either identity over difference or the reverse. In the case of ‘the black pot’, the realist ontology prefers difference over identity. In the case of ‘the qualified object is the mere object’, the same ontology prefers identity over difference. Accordingly the ontological ‘entity’ gets projected. This is perhaps because the realist ontology is guided by Ockham’s razor and the grammatical classification of objects.

Opening the black pot: A service design-driven approach to understanding the use of cleaner cookstoves in peri-urban Kenya

Decades of efforts to replace traditional cooking methods that rely on solid biomass fuels with cleaner-burning and more energy-efficient cookstoves have fallen short of expectations, typically because the new stoves are only used for a short time, or they fail to fully displace the traditional methods. This points to a need to better understand how cookstove users assign value to the new cooking technologies. Recent research has shown that service design methods can help cookstove developers and programme implementers to better understand users’ values, preferences, and needs and improve the stoves and supporting services to achieve greater success. This study builds on that work by combining service design methods and quantitative monitoring of cookstove usage in a small-scale pilot project to introduce clean burning biomass pellet cookstoves in two peri-urban areas outside Nairobi, Kenya. It identifies three different user archetypes, based on their primary motivation for trying new stoves – saving money, convenience, and health and safety. It finds critical weaknesses in the pilot intervention from the perspective of each archetype, and it verifies the findings of the qualitative analysis by reviewing the corresponding stove use monitoring data.

A solar thermal experiment with parabolic dish solar cookers for developing countries

A solar thermal experiment for the thermal performance evaluation of parabolic dish solar cookers suitable for developing countries is presented. Three different solar cooking pots are compared experimentally using three different cooking fluids, namely water, sunflower oil and olive oil. The heating experiments are carried using three identical parabolic dish solar cookers. The mass of the fluid load used in the experimental tests is 2.5 kg, on each test day. The pots that are experimentally tested under Mahikeng, South Africa, conditions are a black stainless steel pot, an aluminium silver pot and a copper pot. The stainless steel black pot shows higher temperatures as compared to the other pots. Higher energy efficiency values are also obtained with the parabolic dish solar cooker using the black stainless steel pot. The absorbing colour of the cooking pot has a more significant effect on the cooking performance than thermal conductivity of the pot. The best heat transfer fluid which obtains higher temperatures and higher cooking efficiencies is sunflower oil. The aluminium silver pot shows the lowest energy efficiencies in almost of all of the experiments. For Mahikeng conditions, the greatest cooking potential in terms of the speed of cooking is shown by the black pot using sunflower oil as the heat transfer fluid. The thermal performance in the cooking experiments is affected by ambient conditions and manual solar tracking. To shorten cooking times, a larger parabolic dish solar cooker can be used.

Experimental Comparison Analysis of White Coated and Black Coated Inside Box Type Solar Cooker

The need to cook food for sustenance is fundamental to nearly every society and requires the expenditure of energy in some form. Solar energy can be harnessed to meet this need without the environmental and health problems associated with most other fuels. There are a wide variety of devices designed to capture the sun’s energy and harness it for cooking food. The aim of this paper is to report comparisons and analysis made between box type solar cookers with the same dimension, shape and size by differentiating coated inside white and black coated. The experiment takes place at morning 10:30-12:50 (Ethiopian local time). It uses standard water boiling test. Water with the same volume put inside the black pot and compare which box boils the waterquicker. From the experiment, the maximum water temperature recorded 75.63oC from white coated and 68.62oC from blackcoated at the same time. Input energy is the same for both solar cookers based on this maximum useful energy for boiling thewater recorded at 4:50 pm, the result Eout white coated 6501.26 J and Eout black coated 5660.87 J. Finally the test results indicate the white-coated reflect the input solar energy without absorbing to the black pot this brings white coated solar box is efficient as compare with black coated.

Response to the Book Review Symposium: Steven Pinker, The Better Angels of Our Nature

They say that ideology is like breath: you never smell your own.1 And so I was not surprised to see my book The Better Angels of Our Nature: A History of Violence and Humanity described as ‘ideological’ by reviewers who strike me as black pots in glass houses casting the first stone. By the same token, it is not easy for an author to defend himself against such an accusation: ‘I am not ideological’ is bound to sound as convincing as ‘I am not a crook’ and ‘I did not have sex with that woman.’ But I will take my chances. The arguments in The Better Angels of Our Nature are in fact not ideological. They are empirical, though the facts on which those arguments are based are bound to gore some oxen of the hard left, critical theory, and various forms of post-X-ism (together with certain livestock of the hard right, libertarianism, and anarchism). As I note in the preface, and as the paper and internet trails of my writing confirm, Better Angels was inspired by my coming across diverse datasets showing historical declines in violence. The existence of these declines (such as homicide since the Middle Ages, corporal and capital punishment since the 18th century, great-power wars since 1945, and autocracies since the 1980s) are well accepted by the scholarly communities who study them, but they surprised me at the time, continue to surprise most readers, and are adamantly denied by those who are unfamiliar with the relevant literatures.

CARACTERIZAÇÃO QUÍMICA DE RESÍDUOS DE ORIGEM ANIMAL E COMPORTAMENTO DE EISENIA ANDREI

This research aims to value the chemical composition, the food preference and the earthworms Eisenia andrei (Bouche, 1972) multiplication, from animals residues. The used residues were bovine rumen content, rabbits manure, ovine manure and bovine manure. The evaluation of vermicomposting process consisted of four treatments with six repetitions. PVC black pots containing 2 kg of the dry matter residues were used for each one of the repetitions, in which 90 clitellates earthworms were inoculated. It was evaluated the residues chemical composition at the time of the experiment installation, and after 90 days of vermicomposting were carried out the earthworms reproduction. The evaluation of food preference consisted four repetitions for each studied residues. PVC role pots with each treatment residues inside, were introduced in a composted with earthworms. The food preference was valued by the residues after 14 days. The food preference and the earthworms’ reproduction are favored by the bovine manure and by the rumen bovine content. The rabbit manure has higher levels of chemical nutrients and heavy metals then the bovine manure, ovine manure and rumen bovine content.

El cantarito: una forma de curar el espanto en una comunidad zapoteca

The author presents a Zapotec text for curing gàl ryà'ld, 'susto' or 'fright' in San Pablo Güilá, Oaxaca. It is called "The Little Jug". Gàl ryà'ld is caused by an accident or anger, where the victim's soul abandons the body, causing symptoms such as loss of appetite, insomnia, colds, fever, et cetera. In the ceremony, the curer uses the chant analyzed here and the music from drumming with the hands over the mouth of a black pot in order to recuperate the person's soul.

Investigation of roman age pigments found on pottery fragments

This work deals with the study of the physico-chemical characteristics of pigments found on pottery fragments from an excavation in Vicenza (Contrà Pedemuro S. Biagio). The examined pigments were: a blue colour on a terracotta fragment; an olive green on a black pot bottom; yellow traces on a red depurated terracotta; an olive green plate bottom with an amaranth “a fresco” test; a deep red on a depurated terracotta; a white trace, again on a depurated terracotta. The techniques used were optical microscopy, scanning electron microscopy (SEM), equipped with an energy dispresive (EDS) microanalysis detector, X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. Most of those techniques were non-destructive and able to provide the required results. All the pigments belonged to the group of basic colours, we did not find “precious” pigments. They have many similarities to those discovered in other European sites in France and Switzerland, witnessing the active trading exchange in which X a Regio, Venetia et Histria played an important role.

I Want to Buy a Black Pot

Cooking pots made by craft specialists in a neighborhood in a small city in the Philippines are hand made, using the paddle and anvil technique, and then slipped with an iron-rich clay and polished with a marine shell. They are fired in an open fire, removed while very hot, and immersed in a bed of rice chaff. The result is a shiny black pot that is easily recognized in the market as being the product of this neighborhood. Such pots are valued by consumers as more beautiful and durable compared with pots made elsewhere. To see if the iron and carbon surface treatments improve the performance of the cooking pots, 50 pots were commissioned, with surfaces that varied from no treatment to slip only or carbon only as well as both carbon and slip. This collection was tested at the University of Arizona, and results clearly indicate that heating effectiveness is improved with both slip and carbon present. The surface treatments of red slip and smudge also affect the performance of pots for water permeability. However, our tests show no obvious relationships between strength and different surface treatments. The project illustrates the power of combining ethnoarchaeology with experimental studies in understanding artifact design.

Stimulating Asparagus Seedling Shoot Production with Benzyladenine

Table 1. Effect of BA sprays on subsequent shoot emergence of asparagus seedlings from 26 Nov. to 21 Dec. 1990 (10 to 35 days after spraying). The progressive emergence of asparagus (Asparagus officinalis L.) spears is caused by apical dominance shoot inhibition. Applied cytokinins may affect apical dominance by releasing lateral shoot buds from inhibition (Philips, 1969). Applying kinetin directly to buds induced axillary shoot stimulation in poinsettia (Euphorbia pulcherrima Willd.) (Milbocker, 1972) and branching in Kalanchoe tormentosa Bak. (Lyons and Hale, 1987). N-(phenylmethyl)-lH-purine-6-amine (benzyladenine, BA) also released axillary apple (Malus domestica Borkh.) buds from correlative inhibition (Green and Autio, 1989). Field drenching asparagus crowns with BA at 25 and 50 mg·liter reduced spear emergence and yield (Benson, 1970). Soaking 1-year-old crowns in BA at 200 mg·liter did not affect asparagus bud inhibition (unpublished data); however, the effects of applying BA to asparagus ferns have not been reported previously. The objective of this study was to determine the effect of foliar BA applications on shoot emergence and growth of potted asparagus seedlings outdoors. ‘Mary Washington’, ‘UC 157 F1 ’, and ‘UC 157 F2’ asparagus cultivars were grown outdoors on benches in 25 × 25 × 20-cm (height and upper and lower diameters) black pots containing a 3 peatmoss : 1 perlite : 1 vermiculite (by volume) soilless medium with a pH of 6.2. Three seeds were planted per pot on 18 July 1990. Seedlings were thinned to one plant per pot. During the growing period, the plants were fertilized monthly with 10 g of l0N-4.5P-8.3K granular formulation per pot and watered as needed. After 4 months (16

Container and Production Bed Mulch Effects on Media Temperatures and Growth of ‘Hershey’s Red’ Azalea

Abstract Three pot/mulch combinations and 2 pot spacings were evaluated as to their effects on growing-media temperatures and growth of ‘Hershey’s Red’ azalea (Rhododendron Xsp.). The highest, maximum temperature and least root and shoot growth occurred in black pots on white clam shell mulch compared to white pots on black polyethylene and to white plywood-shielded pots. Close spacings of pots increased root growth with black pots on white mulch but not with white pots on black mulch. Plants in black pots on white mulch developed the greatest winter foliage discoloration and leaf abscission.

On the Micrometeorology of the Cultivated Pot

There have been only a few reports which demonstrated the micrometeorology of the cultivated pot. The objective of this study is to elucidate the effect of albedo of the pot wall on soil environment in pot. For this purpose, four different wall conditions were prepared using Wagner pots (1/2000a). The outer surface of pots were coated with black lacquer, covered with aluminum film by vaporization, respectively, while one pot was buried almost in a level with the ground. On May 13, 1977, the seedlings of carrot (cultivar ‘MS yonsun’) were planted at the center and at four positions off the center towards east, west, south and north in each pot. Observations terminated on July 16. The features of the distribution of direct solar radiation on the pot wall, of soil temperature, soil moisture and the growth of carrot in the pot were investigated.The diurnal course of direct solar radiation on the pot wall varied according to directions of the pot wall. The daily amount was greatest at the east and west walls, and 52 percent as much as that on a horizontal surface. At the north and south walls the ratios were calculated to be 19 and 10 percent, respectively. The directional distribution of solar radiation affected greatly the soil temperature in the pot.Soil temperature and soil moisture in each pot were affected by albedo of the pot wall, and its effect was more remarkable in the black pot. The range of variation of the soil heat quantity at the center of the black pot was 1.37 times as large as those of the control and the aluminum-covered pots, and was about 5.5 times that of the buried one on June 9. Soil moisture was lowermost in the black pot, in which the moisture decreased markedly in the daytime and recovered only slightly at night.Dry matter weights of carrot roots at the south position and east position of the control pot and at the center of the black pot were relatively larger than those in the other conditions. Differences in the dry matter weight of root were recognized as significant only in the black pot, in which the accumulated soil temperature (May 13-July 16) was negatively correlated with top and root dry matter weights, it almost of the same experimental results in other reports.
