The notion of process in nonstandard theory and in Whiteheadian metaphysics

In this article I intend to show that certain aspects of A.N. Whitehead's philosophy of organism and especially his epochal theory of time, as mainly exposed in his well-known work Process and Reality, can serve in clarify the underlying assumptions that shape nonstandard mathematical theories as such and also as metatheories of quantum mechanics. Concerning the latter issue, I point to an already significant research on nonstandard versions of quantum mechanics; two of these approaches are chosen to be critically presented in relation to the scope of this work. The main point of the paper is that, insofar as we can refer a nonstandard mathematical entity to a kind of axiomatical formalization essentially 'codifying' an underlying mental process indescribable as such by analytic means, we can possibly apply certain principles of Whitehead's metaphysical scheme focused on the key notion of process which is generally conceived as the becoming of actual entities. This is done in the sense of a unifying approach to provide an interpretation of nonstandard mathematical theories as such and also, in their metatheoretical status, as a formalization of the empirical-experimental context of quantum mechanics.

The Process of Greening Cycle as Method of Operative Environmental

The structural change of society from product-based business to service- and further to need-based business has caused the fact that work for environmental issues has spread from conventional factories and environmentally harmful production to concern services and offices as well. Almost every company has an office, so a relatively small environmental burden caused by an individual office grows remarkable already at the state level and globally even more. Motivation to work for environmental issues in an individual office could be challenging even without the fact that wasted environmental impacts bound also wasted costs. Besides cost savings, a concretely greener image of a company has its value in the B2Cas well as in the B2B-field. Consumers and clients are more and more conscious of environmental issues and demand concrete actions instead of speeches, good thoughts and meaningless certifications. Internal work for environmental issues at a strategy level is not sufficient, so operational environmental management is needed for changing old practices. This research is about the effects of operative environmental management on the greening process of an office-based business. The research is outlined to concern the operative work in the office including field sales. Target was to concretely lower the environmental impacts of Lyreco Finland and to find cost savings directly by changing the operative practices in the office and also indirectly by affecting the level of environmental knowledge of the personnel. During the greening process, the aim was also to create concrete arguments for marketing as well. The circle of greening process, which was especially created for this diploma work, was used as a method. The circle divides a year to themes and sections separated by factors of environmental impacts. Separation is based on Brett Wills’ thoughts of seven green wastes (Wills, Brett. The Green Intensions. 2009) and follows it uneasily. The circle aimed at ensuring evolutionary growth of knowledge instead of being revolutionary in the changing process. Committing personnel to the process from its start by asking ideas from them and giving them clear directions was an important part of the research of operative management. Because of working from distance, communication with personnel was operated by frequent training days and weekly greening notes via emails and intranet. Also availability for communication was an important task because of the telecommuting. Research results of this work show that operative environmental management in an officebased business today is mostly management of change. When the strategic environmental friendliness is taken into a concrete level, the most important individual factor is motivating the operating personnel. Research shows that evolutionary change is found being an efficient way to make a change. Also understanding one´s own impact on the environmental burden and on the whole greening process clearly motivates the personnel. Results show that in the operative realization of the greening process, clear directions of new working practices, being as concrete as possible, and committing personnel to follow them make the process more effective. The operative environmental management and the cycle of the greening process decrease the environmental burden and save costs. The concrete results could be used as believable arguments in marketing and therefore exploited in communication with interest groups. Commitment of the management is also one of the key factors of success in the greening process. In this research, changes in the business field by a company trade took the focus of the management away from the greening process and made the process more inefficient by decreasing the amount of training days. The circle of greening process will be used as a tool in the future, as well, and therefore it will help observe environmental impacts of a company and increase sustainable development. Commitment of management to the evolutionary environmental work helps the operating personnel lower environmental impacts, decrease costs and build a concretely greener image.

Immateriellt kulturarv som begrepp och process : folkloristiska perspektiv på kulturarv i Finlands svenskbygder med folkmusik som exempel

Cultural heritage has become something of an in-word in recent times. Intangible cultural heritage, however, is a category that has received relatively little attention. This folkloristic study focuses on intangible cultural heritage as concept and as process. Folkloristics as a scholarly branch emphasizes non-material culture. Consequently, there is a big potential in bringing existing knowledge of folklore together with current scholarly theories concerning cultural heritage in order to expand the understanding of intangible cultural heritage. In this thesis cultural heritage is regarded as a symbolic construct, which is spoken of and discussed in specific ways. The study of intangible cultural heritage (Swe. kulturarv) as concept focuses on this area. For a cultural component to be experienced as intangible cultural heritage it is, however, not enough to discuss it in those terms. Instead, cultural heritage status needs to be acted out during lengthy processes. This is demonstrated by the study of intangible cultural heritage as process. As a consequence performativity appears crucial to an understanding of cultural heritage – when a sufficient number of people speak and act as if a cultural component has a special status, it will also be perceived as cultural heritage. In this dissertation intangible cultural heritage is studied through cultural analysis, more specifically through discourse analysis. The usage of the concept intangible cultural heritage within cultural organizations, in scholarly use and in the Swedish-speaking press in Finland is examined. Traditional music in the Swedish-speaking districts of Finland is used as a case study of intangible cultural heritage as process. The examination concerns how traditional music, an intangible cultural component, has been discussed, transformed, standardized and objectified in a cultural heritage process. Cultural heritage is generally used as a token of value so that certain cultural components, both intangible and tangible, which are discussed in terms of cultural heritage are perceived to be valuable and should therefore be safeguarded. Intangible cultural heritage depends on performance, that is practitioners use their bodies to act out their traditional knowledge through song, handicraft, storytelling and so on. Intangible cultural components can be transmitted to other individuals in a performance situation, and they can also be documented. In Finland documentation and subsequent filing in archives have been associated with safeguarding of intangible cultural heritage. If the aim of safeguarding is to uphold traditional practices, which is the case for among others UNESCO’s programs aimed at intangible cultural heritage, other efforts are called for: forms of safeguarding that support performance and transmission.

Integrating environmental aspects into product development process

Various regulations and customer requirements have made it necessary for Vacon Oyj to pay more attention to the environmental aspects in its processes. The main purpose of this master’s thesis project is to define how environmental aspects could be integrated into Vacon’s product development process. The aim is to find out the most important environmental aspects for the company to address, to examine how these could be taken into account during the development process and to map the critical factors that need consideration in order to ensure the successful integration of environmental aspects into the design process. Based on the customer requirements and evolving regulations the most important aspects for Vacon include minimizing the amount of harmful substances, improving the recyclability and energy efficiency of the product and moreover providing meaningful information related to these aspects. To tackle these issues, a new DfE process was developed, tasks in each phase were described and responsibilities were indicated. To ensure the success of the DfE process, management commitment, support of other processes and significant improvements in ways the information is managed are required. The developers should be provided with training and support. Environmental expertise and knowledge in-house should be developed and establishing meaningful environmental indicators is suggested.

The effect of wood supply and bleaching process on pulp brightness stability

One hundred different 5.5-year-old Eucalyptus grandis x Eucalyptus urophylla wood clones were cooked to kappa number 15-17.5 and the resulting kraft pulps oxygen-delignified to kappa 9.5-11.5 under fixed conditions, except for chemical charges. Thirteen samples showing large variations in effective alkali requirement, pulp yield and O-stage efficiency and selectivity were selected for brightness reversion studies. These samples were bleached to 90-91% ISO by DEDD and DEDP sequences and their brightness stability and chemical characteristics determined. Heat reversion of the eucalyptus kraft pulps was strongly influenced by the wood supply, with brightness loss varying in the range of 2.1-3.6 and 0.8-1.7 %ISO for ODEDD and ODEDP bleached pulps, respectively. Pulps bleached by the ODEDP sequence showed reversion values 1.3-1.9 % ISO lower than those bleached by the ODEDD sequence. Pulp carbonyl content decreased by 35-40% during the final peroxide bleaching stage. Carbonyl and carboxyl groups correlated positively with brightness reversion, as did permanganate number and acid soluble lignin. Pulp final viscosity and metal and DCM extractives contents showed no significant correlation with brightness reversion. Pulping, oxygen delignification and ECF bleaching performances also showed no correlation with brightness reversion.

Mikkelin Pursialan pohjavesialueen haitta-aineet

Mikkelin talousvedestä kahden kolmasosan tullessa Pursialan pohjavesialueelta on alueen suojeleminen tärkeää. Pohjaveden laatua uhkaavat etenkin alueella sattuneet pohjavedenpilaantumistapaukset. Merkittävimmät pohjaveden pilaantumistapaukset ovat VAPO Oy:n sahan aiheuttama pohjaveden pilaantuminen kloorifenoleilla (CP) ja VR:n ratapölkkykyllästämön aiheuttama pohjaveden pilaantuminen kreosoottiöljyllä sekä Rinnekadun Nesteen aiheuttama pohjaveden pilaantuminen MTBE:llä. Alueella on tehty tutkimuksia ja kunnostuksia pilaantumiin liittyen, mutta näiden tuloksia ei ole aikaisemmin koottu yhteen. Tämän työn tavoitteena oli koota tulokset samaan aineistoon. Työssä keskityttiin kloorifenolien leviämisen tarkasteluun sen Pursialan pohjavedenottamolle muodostaman suurimman uhan vuoksi. Kallioperätietojen, maanpintatietojen ja näytetietojen pohjalta laadittiin myös pienoismalli CP-pilaantuman leviämisen kokonaiskuvan hahmottamiseksi. Työn tavoitteena oli lisäksi tehdä riskitarkastelua CP-pilaantumaan liittyen ja etsiä keinoja hallita havaittuja riskejä. Riskinhallintaan liittyen työssä tutkittiin kloorifenoleilla pilaantuneen alueen maaperä- ja kalliotietoja sekä pohjaveden laatutietoja. Pursialan pohjavedessä on runsaasti rautaa ja mangaania sekä aggressiivista hiilihappoa. Pohjaveden pH on alueella noin 6,5, lämpötila noin 7,5 ºC ja happipitoisuus noin 0,7 mg/l. Pursialan kaupunginalueen kallioperässä on havaittavissa VAPO Oy:n sahalta vedenottamolle etenevä kalliopainanne, jota pitkin CP etenee. Alueen kallioperä on kiillegneissiä, jossa on pohjois–etelä-suuntaista rakoilua. Maaperätuloksien perusteella on havaittavissa vettä hyvin johtavien maakerrosten jatkuminen koko vedenottamon ja sahan välisen matkan, mikä tarkoittaa, että CP-pitoisella pohjavedellä voi olla aiemmin oletettua nopeampikin yhteys sahalta vedenottamolle. Suurin CP-pitoisuus noin 100 000 µg/l on mitattu KY-5-altaan kohdalle asennetun M14-pohjavesiputken pohjasta. Talousvesiasetuksen raja-arvo CP:lle on 10 µg/l. Sahan ja vedenottamon puolivälissä on havaittu yli 10 000 µg/l meneviä CP-pitoisuuksia. Suurin vedenottamon kaivoista (kaivo 10) mitattu pitoisuus on 149 µg/l. Jakotukilta raakavedestä otetuissa näytteissä tai talousvedessä ei ole kuitenkaan havaittu talousvesiasetuksen ylittäviä CP-pitoisuuksia. Pienoismallin perusteella CP sijaitsee sahan alueella lähellä kallionpintaa ja hajaantuu koko pohjavesipatjaan vedenottamolle päin mentäessä. CP-mittaustuloksissa on havaittavissa pulssimaisuutta. Tämä johtuu todennäköisesti Saimaan pinnan vaihtelun seurauksena muuttuvasta rantaimeytyneen pohjaveden määrästä. Saimaan pinnan nousu näyttäisi tuloksien perusteella nostavan CP-pitoisuuksia saha-alueella ja laskevan lähellä vedenottamoa. Pohjaveden pintatietojen perusteella tehdyn tarkastelun mukaan pohjavesi voi kulkeutua sahalta vedenottamolle parhaimmillaan noin vuodessa. Työssä arvioitiin KY-5–liuoksen vuosittaiseksi käyttömääräksi noin 648–970 m3. Allassakkaa arvioitiin syntyneen yhteensä noin 10–31 m3. Pohjaveteen arvioitiin joutuneen toiminnan aikana yhteensä noin 3 000–4 000 kg CP:tä. Kloorifenolit esiintyvät pohjavedessä lähes täysin kloorifenolaatteina. Kloorifenolien hajoaminen ja muuntuminen pohjavedessä on epätodennäköistä. Käsitteellisen mallin mukaan kloorifenolipilaantuman suurimmat riskit aiheutuvat kloorifenolien mahdollisuudesta pilata Pursialan vedenottamon talousvesi. Tällä hetkellä riskejä hallitaan kloorifenolien leviämisen tarkkailulla, sahan ja vedenottamon puolivälissä sijaitsevalla koepumppauksella sekä varautumalla aktiivihiilijauheen syöttöön talousvesiprosessiin. Koepumppauksen avulla on saatu ylös tällä hetkellä noin 69 kg kloorifenoleita. Tutkimuksen perusteella suositeltavimmat riskinhallintatoimet tulevaisuudessa ovat sahalla sijaitseva kunnostuspumppaus, sahan ja vedenottamon väliin sijoittuva suojapumppaus- ja vesiverhoyhdistelmä sekä sahan rannan kautta tapahtuvan rantaimeytymisen estäminen.

Spectrometrical Monitoring of Laser Sintering Process of Ceramic Material

This thesis is done as a part of project called FuncMama that is a project between Technical Research Centre of Finland (VTT), Oulu University (OY), Lappeenranta University of Technology (LUT) and Finnish industrial partners. Main goal of the project is to manufacture electric and mechanical components from mixed materials using laser sintering. Aim of this study was to create laser sintered pieces from ceramic material and monitor the sintering event by using spectrometer. Spectrometer is a device which is capable to record intensity of different wavelengths in relation with time. In this study the monitoring of laser sintering was captured with the equipment which consists of Ocean Optics spectrometer, optical fiber and optical lens (detector head). Light from the sintering process hit first to the lens system which guides the light in to the optical fibre. Optical fibre transmits the light from the sintering process to the spectrometer where wavelengths intensity level information is detected. The optical lens of the spectrometer was rigidly set and did not move along with the laser beam. Data which was collected with spectrometer from the laser sintering process was converted with Excel spreadsheet program for result’s evaluation. Laser equipment used was IPG Photonics pulse fibre laser. Laser parameters were kept mainly constant during experimental part and only sintering speed was changed. That way it was possible to find differences in the monitoring results without fear of too many parameters mixing together and affecting to the conclusions. Parts which were sintered had one layer and size of 5 x 5 mm. Material was CT2000 – tape manufactured by Heraeus which was later on post processed to powder. Monitoring of different sintering speeds was tested by using CT2000 reference powder. Moreover tests how different materials effect to the process monitoring were done by adding foreign powder Du Pont 951 which had suffered in re-grinding and which was more reactive than CT2000. By adding foreign material it simulates situation where two materials are accidently mixed together and it was studied if that can be seen with the spectrometer. It was concluded in this study that with the spectrometer it is possible to detect changes between different laser sintering speeds. When the sintering speed is lowered the intensity level of light is higher from the process. This is a result of higher temperature at the sintering spot and that can be noticed with the spectrometer. That indicates it could be possible to use spectrometer as a tool for process observation and support the idea of having system that can help setting up the process parameter window. Also important conclusion was how well the adding of foreign material could be seen with the spectrometer. When second material was added a significant intensity level raise could be noticed in that part where foreign material was mixed. That indicates it is possible to see if there are any variations in the material or if there are more materials mixed together. Spectrometric monitoring of laser sintering could be useful tool for process window observation and temperature controlling of the sintering process. For example if the process window for specific material is experimentally determined to get wanted properties and satisfying sintering speed. It is possible if the data is constantly recorded that the results can show faults in the part texture between layers. Changes between the monitoring data and the experimentally determined values can then indicate changes in the material being generated by material faults or by wrong process parameters. The results of this study show that spectrometer could be one possible tool for monitoring. But to get in that point where this all can be made possible much more researching is needed.

Sahan ohjausjärjestelmä myynti- ja toimitusketjun apuvälineenä sahan kannattavuuden kehittämisessä

Diplomityössä tarkasteltiin sahalaitokselle investoidun tuotannon ohjausjärjestelmän toimivuutta ja käytettävyyttä. Tutkimuksessa vertailtiin aikaisemmin suunnittelun apuna toimineita järjestelmiä uuteen ohjausjärjestelmään. Tavoitteena oli selvittää onko uuden järjestelmän sisäänajo onnistunut niin, että se tuottaisi oikeaa tietoa sahausprosessista. Tutkimuksessa tarkasteltiin myös kuinka sahan uutta ohjausjärjestelmää voitaisiin hyödyntää yrityksen myynti- ja toimitusketjun kannalta parhaiten ja huomioiden erityisesti kannattavuuslaskennallinen näkökulma. Lisäksi pohdittiin integraatiomahdollisuuksia yrityksessä käytössä oleviin muihin suunnittelujärjestelmiin. Tutkimuksen taustalla on sahateollisuuden entisestäänkin kiristynyt tilanne ja toisaalta tarve tulevaisuuden suunnitelmallisuuden parantamiseen. Kilpailussa mukana pysyminen edellyttää sahausprosessista saatavan tietomäärän keräämistä, tallentamista ja ennen kaikkea tiedon parempaa hyväksikäyttöä. Tutkimuksen kohteena ollut sahalaitos vastasi tulevaisuuden tiukentuneisiin olosuhteisiin investoimalla uuteen ohjausjärjestelmään ja uskoi siitä saatavan hyödyn auttavan heitä parantamaan sekä yksittäisten tuotteiden että koko tuotevalikoiman kannattavuutta. Ohjausjärjestelmän toivottiin tuovan todenmukaisempaa ja monipuolisempaa tietoa yrityksen suunnittelutyölle. Sahalaitoksen kannattavuuden parempi seuraaminen ja tuotevalikoiman sekä suunnittelun parempi kohdentaminen helpottuu sähköisen ohjausjärjestelmän avulla huomattavasti. Ohjausjärjestelmän kautta kannattavuuden tunnusluvut saadaan nopeammin myynti- ja toimitusketjun tietoon, poikkeamiin pystytään puuttumaan ajoissa ja yleinen tietoisuus sahausprosessista paranee. Ohjausjärjestelmän avulla mahdollistetaan entistä joustavampi koesahaus ja reklamaatioeriin porautuminen onnistuu niin ikään vaivattomammin. Yksi hyödyllinen integraatiomahdollisuus olisi SAP:n ja uuden ohjausjärjestelmän yhdistäminen, jossa hinta- ja reklamaatiotieto saataisiin yhteneväksi. Kun ohjausjärjestelmä saadaan varmuudella tuottamaan oikeaa tietoa sahausprosessista, on siitä saatava hyöty myynti- ja toimitusketjulle todellinen. Kalliin raaka-aineen entistä tehokkaampi hyödyntäminen, tuotepaletin suunnittelu ja myynnin kohdentaminen kannattavimpiin tuotteisiin, ovat tärkeä osa niitä asioita joihin järjestelmä tuo helpotusta. Tulevaisuudessa ohjausjärjestelmän jatkokehitykseen tulisi kiinnittää erityistä huomiota, jotta voitaisiin taata asiakaslähtöisyys ja kannattava tuoterakenne osana menestyksekästä liiketoimintaa.

Software Test Process Development

In this thesis, the components important for testing work and organisational test process are identified and analysed. This work focuses on the testing activities in reallife software organisations, identifying the important test process components, observing testing work in practice, and analysing how the organisational test process could be developed. Software professionals from 14 different software organisations were interviewed to collect data on organisational test process and testing‐related factors. Moreover, additional data on organisational aspects was collected with a survey conducted on 31 organisations. This data was further analysed with the Grounded Theory method to identify the important test process components, and to observe how real‐life test organisations develop their testing activities. The results indicate that the test management at the project level is an important factor; the organisations do have sufficient test resources available, but they are not necessarily applied efficiently. In addition, organisations in general are reactive; they develop their process mainly to correct problems, not to enhance their efficiency or output quality. The results of this study allows organisations to have a better understanding of the test processes, and develop towards better practices and a culture of preventing problems, not reacting to them.

Delay reduction in courts of justice – possibilities and challenges of process improvement in professional public organizations

Delays in the justice system have been undermining the functioning and performance of the court system all over the world for decades. Despite the widespread concern about delays, the solutions have not kept up with the growth of the problem. The delay problem existing in the justice courts processes is a good example of the growing need and pressure in professional public organizations to start improving their business process performance.This study analyses the possibilities and challenges of process improvement in professional public organizations. The study is based on experiences gained in two longitudinal action research improvement projects conducted in two separate Finnish law instances; in the Helsinki Court of Appeal and in the Insurance Court. The thesis has two objectives. First objective is to study what kinds of factors in court system operations cause delays and unmanageable backlogs and how to reduce and prevent delays. Based on the lessons learned from the case projects the objective is to give new insights on the critical factors of process improvement conducted in professional public organizations. Four main areas and factors behind the delay problem is identified: 1) goal setting and performance measurement practices, 2) the process control system, 3) production and capacity planning procedures, and 4) process roles and responsibilities. The appropriate improvement solutions include tools to enhance project planning and scheduling and monitoring the agreed time-frames for different phases of the handling process and pending inventory. The study introduces the identified critical factors in different phases of process improvement work carried out in professional public organizations, the ways the critical factors can be incorporated to the different stages of the projects, and discusses the role of external facilitator in assisting process improvement work and in enhancing ownership towards the solutions and improvement. The study highlights the need to concentrate on the critical factors aiming to get the employees to challenge their existing ways of conducting work, analyze their own processes, and create procedures for diffusing the process improvement culture instead of merely concentrating of finding tools, techniques, and solutions appropriate for applications from the manufacturing sector

Assessing Organizational Cultural Fit prior to Integration in the M&A Process

Yritysostojen määrä on historiallisen suuri 2000-luvulla, vaikka melkein puolet niistä epäonnistuu. Aineettomilla tekijöillä, kuten organisaatiokulttuureilla, on keskeinen rooli yritysostojen onnistumisissa. Myös case yritys on aktiivinen yritysostoissa ja haluaa arvioida integraatioprosessinsa tehokkuutta. Siten diplomityön tarkoituksena on luoda työkalu organisaatiokulttuurien yhteensopivuuden arvioimiseksi, jotta ostopäätöksentekoa sekä integraation suunnittelua voitaisiin tukea paremmin yrityksessä. Diplomityö vastaakin kysymyksiin, kuten miten arvioida kulttuurista yhteensopivuutta ennen integraatiota integraatioprosessin parantamiseksi sekä mitkä ovat olleet kaikkein ongelmallisimmat ja toisaalta kaikkein menestyksekkäimmät kulttuuritekijät tutkitussa integraatiossa. Kulttuurisen yhteensopivuuden arviointi tulisi nähdä prosessina osana yrityskauppaa. Prosessin tulisi alkaa kulttuurisen integraation tavoitteiden määrittämisellä sekä organisaatiokulttuurin käsitteen ymmärtämisellä. Kulttuurianalyysi tulisi suorittaa työpajan avulla. Sen tulisi käsitellä ainakin yhdeksän kulttuurin osa-aluetta: innovatiivisuus, päätöksenteko, ihmissuuntautuneisuus, kommunikaatio, kontrolli, asiakassuuntautuneisuus, ajanhallinta, identifikaatio, sekä kollektivismi. Lisäksi kuhunkin dimensioon liittyvään kysymykseen tulisi vastata pisteillä yhdestä viiteen, jolloin voidaan piirtää kulttuurisen yhteensopivuuden kuvio. Tämän jälkeen johdon tulisi keskustella tuloksista vielä kerran tarkemmin ja lopulta koota tulokset kirjalliseksi raportiksi. Tutkitussa integraatiossa parhaiten integraatiota tukivat ihmissuuntautuneisuus sekä ajanhallinta (työn ja vapaa-ajan välinen tasapaino sekä tulevaisuus-suuntautuneisuus). Haasteellisimmat kulttuuritekijät koskivat päätöksentekoa, kommunikaatiota ja kontrollia, jotka vaikuttavat olevan tyypillisiä ongelmia ison yrityksen ostaessa pienemmän yrityksen.

Application of simulated annealing in simulation and optimization of drying process of Zea mays malt

Kinetic simulation and drying process optimization of corn malt by Simulated Annealing (SA) for estimation of temperature and time parameters in order to preserve maximum amylase activity in the obtained product are presented here. Germinated corn seeds were dried at 54-76 °C in a convective dryer, with occasional measurement of moisture content and enzymatic activity. The experimental data obtained were submitted to modeling. Simulation and optimization of the drying process were made by using the SA method, a randomized improvement algorithm, analogous to the simulated annealing process. Results showed that seeds were best dried between 3h and 5h. Among the models used in this work, the kinetic model of water diffusion into corn seeds showed the best fitting. Drying temperature and time showed a square influence on the enzymatic activity. Optimization through SA showed the best condition at 54 ºC and between 5.6h and 6.4h of drying. Values of specific activity in the corn malt were found between 5.26±0.06 SKB/mg and 15.69±0,10% of remaining moisture.
