Impact of unsymmetrical loads in distribution networks

Since it is virtually impossible to balance loads in three-phase system, unbalance in a varying degree exists almost in all distribution networks. The aim of the thesis is to analyze the impact of this unbalance subject to different configurations of distribution system and winding connection of the supplying transformer. Also impact of the voltage unbalance on the equipment is investigated. In order to make the investigation more visual, the following calculations have been conducted: - Unsymmetrical load in four-wire star connected network - Unsymmetrical load in four-wire star connected network with broken zero conductor (or three-wire network). - Unsymmetrical load when the supplying transformer is so-called zigzag transformer.

Keskijohdon ja työntekijöiden psykologiset sopimukset muutostilanteessa. Case: OP-Pohjola-ryhmä

Tässä tutkielmassa tarkasteltiin keskijohtajien ja työntekijöiden psykologisia sopimuksia OP-Pohjola-ryhmässä. Tutkielman tarkoituksena oli tuottaa uutta ymmärrystä henkilöstön ja organisaation suhteesta. Tavoitteena oli selvittää, millaisia psykologisia sopimuksia keskijohtajat ja työntekijät muodostavat, rikotaanko näitä sopimuksia ja kuinka haastateltavat reagoivat mahdollisiin rikkomuksiin. Lisäksi eri organisaatiotasojen käsityksiä ja näkemyksiä psykologisesta sopimuksesta vertailtiin keskenään. Tutkielma on laadullinen tutkielma, jonka tutkimusmenetelmänä käytettiin puolistrukturoitua haastattelua. Tutkimusaineisto kerättiin tekemällä kahdeksan haastattelua. Tutkimusta varten haastateltiin neljää keskijohtajaa ja neljää työntekijää. Empiirisen aineiston analyysissa tulkinta pohjautuu tutkimuksen teoreettiseen viitekehykseen. Tutkimustulosten mukaan haastateltujen keskijohtajien psykologiset sopimukset ovat luonteeltaan relationaalisia ja työntekijöiden sopimukset puolestaan transaktionaalisia. Molempien sopimukset sisältävät kuitenkin kumpiakin sopimusehtoja. Haastateltujen psykologisia sopimuksia on rikottu harvakseltaan. Rikkomuksiin on reagoitu keskustelemalla työnantajan kanssa tai olemalla vaiti ja sopeutumalla tilanteeseen. Tulokset myös osoittavat, että organisaatiossa vallitsee suuri luottamus ja asioista keskustellaan hyvin avoimesti.

Modificação química e física do amido de quirera de arroz para aproveitamento na indústria de alimentos

The study evaluated the efficiency of chemical (phosphorylation) and physical (extrusion) modifications of the starch of broken rice. Results demonstrated a reduction in the moisture content of extruded and phosphorylated broken rice and an increase in the ash content of phosphorylated broken rice. Both phosphorylation and extrusion increased cold water binding capacity, swelling power, and solubility. Extruded and phosphorylated pastes were stable under refrigeration, but only extruded paste was stable when submitted to freezing. Phosphorylated paste had the lowest viscosity and the highest stability during heating, while the extruded one gelatinized without heating, but had higher losses during heating.

Avaliação das técnicas de precipitação química e encapsulamento no tratamento e destinação conjunta de resíduos líquidos contendo cromo e vidrarias de laboratório

In this paper, we present procedures for the treatment and final disposal of residual solutions containing chromium, in order to evaluate the effectiveness of chemical precipitation of the metal and the potential of the glass encapsulation technique, using broken laboratory glassware. The results demonstrated that pH-values convenient for chemical precipitation are between 10 - 11. With regard to Cr(OH)3 encapsulation, the leaching and solubilization tests allowed to classify the waste as non-dangerous and non-inert. Finally, it is pointed out that the adoption of waste management practices in universities should be encouraged, helping to train professionals skilled in good laboratory practices.

Recuperação de chumbo, mercúrio e elementos dos grupos 4 a 7 da tabela periódica de seus resíduos

This work shows routes to recover some elements from their laboratory wastes and broken apparatus (thermometers and densimeters). Most elements chosen present a chemical behavior in aqueous solution which is not currently studied in the ordinary experimental classes. The routes were based on the previous knowledge of the qualitative composition of the wastes treated. Wastes containing chromium were the most difficult to treat. The elements were recovered in good yields and can be reused in new experiments. This work was a very good experience in chemistry for students and shows the need of managing wastes for a better environment.

Resultados científicos do cruzeiro do "Baependi" e do "Vega" à Ilha da Trindade: contribuição para o conhecimento da plataforma insular da Ilha da Trindade

The oceanographic work realized during 10 days in the surroundings of the eruptive island of Trindade, 20º30'36" lat. S - 29º19'26" long. W, had as principal aim the determination of the insular plateau, whose knowledge was very insufficient. Thus were established some oceanographic stations and sounding lines were realized by means of an echobathymeter whose responses were initially verified with mechanical soundings obtaneid by means of a Thomson sounder. The insular plateau is very narrow and exhibits a sudden fall between the 100 and 120 m. depth line at 740 m. - 2950 m. from the coast. Its greatest depth is of 108,30 m. and its mean inclination is of 8,12%. The plateau of the island of Trindade is separated from that of the neighbouring group of Martim Yaz by great depths. The bottoms are rocky near the coast, the blocks having been produced by the rupture of the magmatic mass of the island. Further away from the coast, the size of the rocks gradually diminishes up to the fine sand thickness. In the litoral zone there are abundant tufts of living Lithothamnion with a rich associated flora and fauna, which partly covers the rocks themselves. Further off at sea, the spheres of the dead alga with its commensals are cimented together by sedimentation. The spheres are further broken up and become an integrating part of the sand. The results of the physical and chemical analyses of the sand bottoms are shown in tables 2 and 3. The coast is either of abrupt rocky walls falling down to sea level, or of shores, made of pebbles or of sand. Anyhow, there are frequently Lithothamnion terraces slightly inclinated towards the bottom (chemical analysis table 1).

Mining in Developing Countries: A Case Study of Sustainability Challenges

Mining has severe impacts on its surrounding. Particularly in the developing countries it has degraded the environment and signigicantly altered the socio-economical dynamics of the hosts. Especially relocation disrupts people from their homes, livelihoods, cultures and social activities. Mining industry has failed to develop the local host and streghten its governance structures; instead it has further degraded the development of mineral rich third world countries, which are among the world poorest ones. Cash flows derived from mining companies have not benefitted the crass-root level that however, bears most of the detrimental impacts. Especially if the governance structure of the host is weak, the sudden wealth is likely to accelerate disparities, corruption and even fuel wars. Environmental degradation, miscommunication, mistrust and disputes over land use have created conflicts between the communities and a mining company in Obuasi, Ghana; a case study of this thesis. The disputes are deeply rooted and further fuelled by unrealistic expectations and broken promises. The relations with artisanal and illegal miners have been especially troublesome. Illegal activities, mainly encroachment of the land and assets of the mine, such as vandalising tailings pipes have resulted in profits losses, environmental degradation and security hazards. All challenges mentioned above have to be addressed locally with site-specific solutions. It is vital to increase two-way communication, initiate collaboration and build capacity of the stakeholders such as local communities, NGOs and governance authorities. The locals must be engaged to create livelihood opportunities that are designed with and for them. Capacity can also be strengthened through education and skills training, such as women’s literacy programs. In order to diminish the overdependence of locals to the mine, the activities have to be self -sufficient and able to survive without external financial and managerial inputs. Additionally adequate and fair compensation practises and dispute resolution methods that are understood and accepted by all parties have to be agreed on as early as possible.

Parents as Pain Killers in the Pain Management of Preterm Infants

Vanhemmat keskoslasten kivun lievittäjinä Tutkimuksen tarkoituksena oli kehittää uusi kivunlievitysmenetelmä, Vanhempien käsikapalo, keskoslasten kivunhoitoon vastasyntyneiden teho-osastolla. Vanhempien käsikapalon tehokkuutta verrattiin kahdessa satunnaistetussa kontrolloidussa crossover-tutkimusasetelmassa ei-lääkkeelliseen näyttöön perustuvaan hoitoon (P.O. glukoosiliuos), lääkkeelliseen menetelmään (I.V. oksikodoni) ja lumeeseen (P.O. vesi) tai kontrolli hoitoon kantapääpiston ja hengitysteiden imemisen aikana. Lisäksi mitattiin kivunhoidon lyhytaikaisia sivuvaikutuksia (hapetuksen- ja pulssinlasku) ja pidempiaikaisia vaikutuksia uneen. Tutkittujen lasten ikä oli 28 raskausviikkoa (n = 20) ja 28 1/7 (n = 20). Toimenpidekipua arvioitiin Premature Infant Pain Profile (PIPP) -kipumittarilla. Interventioiden jälkeen unen rakenne analysoitiin 13 tunnin polysomnografia-rekisteröinneistä. Viimeisessä vaiheessa haastateltiin äitejä (n = 23), jotka olivat käyttäneet vanhempien käsikapaloa 2–4 viikkoa vastasyntyneiden teho-osastolla, strukturoidulla the Clinical Interview for Parents of High-Risk Infants -haastattelulla, johon oli lisätty kysymyksiä lapsen kivunhoidosta. Kantapääpiston aikana PIPP–pisteet olivat merkitsevästi matalampia P.O. glukoosiliuoksella (ka 4,85 ± 1,73, p ≤ 0,001) ja vanhempien käsikapalolla (ka 5,20 ± 1,70, p = 0,004) verrattuna lumeeseen (ka 7,05 ± 2,16). Hengitysteiden imemisen yhteydessä PIPP–pisteet olivat matalampia P.O. glukoosiliuoksella (ka 11,05 ± 2,31, p = 0,014) ja vanhempien käsikapalolla (ka 11,25 ± 2,47, p = 0,034) verrattuna lumeeseen (ka 12,40 ± 2,06). Oksikodonin teho oli verrattavissa lumeeseen kummankin toimenpiteen aikana. P.O. glukoosiliuoksen (21,3 %) ja lumeen (12,5 %) annosteluun liittyi merkittävästi enemmän lyhytaikaisia sivuvaikutuksia verrattuna oksikodoniin (5 %) tai vanhempien käsikapaloon (5 %). Oksikodoni muutti keskoslasten unen rakennetta vähentämällä merkittävästi aktiivisen unen määrää verrattuna muihin hoitoihin. Vanhemmat suhtautuivat positiivisesti käsikapalon käyttöön. Äitien osallistuminen kivunhoitoon voitiin jaotella kolmeen eri tyylin, jotka selittyivät äidin kiintymyksen tunteilla ja lapsen tehohoitoon liittyvällä stressillä. Vanhempien käsikapalo on suositeltavampi lyhyen toimenpidekivun lievittäjä kuin P.O. glukoosiliuos tai I.V. oksikodoni, kun tehokkuus, turvallisuus ja perhe otetaan huomioon.

Key factors to inoculate Botrytis cinerea in tomato plants

Studies addressing the biological control of Botrytis cinerea have been unsuccessful because of fails in inoculating tomato plants with the pathogen. With the aim of establishing a methodology for inoculation into stems, experiments were designed to assess: i. the aggressiveness of pathogen isolates; ii. the age at which tomato plants should be inoculated; iii. the susceptibility of tissues at different stem heights; iv. the need for a moist chamber after inoculation; and v. the effectiveness of gelatin regarding inoculum adhesion. Infection with an isolate from tomato plants that was previously inoculated into petioles and then re-isolated was successful. An isolate from strawberry plants was also aggressive, although less than that from tomato plants. Tomato plants close to flowering, at 65 days after sowing, and younger, middle and apical stem portions were more susceptible. There was positive correlation between lesion length and sporulation and between lesion length and broken stems. Lesion length and the percentage of sporulation sites were reduced by using a moist chamber and were not affected by adding gelatin to the inoculum suspension. This methodology has been adopted in studies of B. cinerea in tomato plants showing reproducible results. The obtained results may assist researchers who study the gray mold.
