Abstract:
Clean rooms are traditionally classified as either laminar flow or mixed flow rooms. Although these two types of rooms operate quite differently, they have generally been used in the same manner, with the same rules applying to both types, on the assumption that there was a unidirectional flow in both types. Experiments have shown that this is not the case in the mixed flow rooms. In some cases vertical counterflows have been shown to carry contaminants all the way to the ceiling of such rooms. In the dilution controlled clean room concept, the air is sufficiently stirred to achieve good mixing. With a homogeneous concentration of particles in the air, the steady state particle concentration can be calculated. Particle concentration may be controlled by adjusting the air flow to maintain the concentration at a constant value. Under these conditions, only enough air must be circulated to carry away the particles currently being generated. This means that energy consumption is directly related to the particles being generated in the room and is therefore a practical as well as theoretical minimum.

Abstract:
Small particle contamination analysis requires consideration of secondary contamination of our sampie. Protection of such samples is very important. The procedure for sampling with freshly pulled lengths of clear 3M Magic™ tape is a favorite procedure among forensic microscopists. The tape must be immediately pressed onto a clean surface; usually, a clean microscope slide. There it is protected from further contamination.Microscopical study and identification is usually possible utilizing the tape backing as a coverslip. Its thickness Is about 56 μm, one-third of the recommended 170 μm, but quite adequate for objectives 4-20X, If you feel persnickety, you can use two thicknesses of the tape, a second one over the sampling tape, This will give you optimum images for 4-40X objectives. Three thicknesses of tape, at 168 μm, is very close to the recommended thickness of 170 μm for any or all objectives.

Abstract:
Statement of the problem. In modern industry, clean room technology is commonly used to monitor the state of the air. The use of toxic gases in clean rooms might result in emergencies that call for emergency ventilation. In order to calculate the emergency air exchange, it is necessary to design a model of emergency air exchange considering a significant number of influencing factors. Results. The model of emergency air exchange for a clean room is developed based on the equation of material balance on the harmful gas allocated from the equipment in case of an emergency. The solution of the model of the emergency air exchange for a clean room is obtained allowing the concentrations of harmful gas to be calculated depending on a specific emergency. The properties of the resulting solution are investigated. The concept of accumulating capacity of the ventilated room is introduced and the influence of accumulating capacity on change of concentrations of harmful gas is evaluated.Conclusions. The performed calculations allow one to understand the processes of development of an emergency situation in a clean room more profoundly and to allow for these risks while designing emergency ventilation of clean rooms.

Abstract:
This thesis aims to confirm a proof of concept on how to get a robot to pick up a plastic bag containing 3500 plastic caps, cut it open and pour the content, all within a restricted Clean room. The work was executed in an agile way with several ongoing iterative processes in parallel. In the present production line, refilling caps are done manually. For those working in the production line, this task entails heavy lifting and the concern of keeping an eye out for when to refill and how many caps there are in the production line all the time. The result is a working prototype of a robot tool, consisting of a combined clamp and vaccum bag gripper and a self standing linear unit with a blade mounted to it. When tested, this proved to be a functioning solution to the task in hand. The gripper is designed to be mounted on a six axis industrial robot and the blade is placed inside a robot cell. Simulations show that the task is easily done fast enough to supply 5 production lines, producing in full speed,with caps. Solely this unit will not contribute much to a production line if implemented in a factory, since it does not take material flow into consideration. It can merely be seen as a part of a bigger automation chain.

Abstract:
Aerosol particle deposition rates on surfaces inside a clean room are predicted by a model developed to account for particle convection, diffusion and sedimentation. External forces acting on the particle also influence the rate of deposition. Both electrical charge build up on product surfaces and temperature gradients in the air near the product surface are known to effect the rate of deposition. A description of an electrostatic and thermophoretic force on the particle is thus included in the model. The equations governing the particle deposition process and the approach used in obtaining a solution to these equations are both described. A finite element numerical solution is detailed, followed by a description of the electrostatic force models. Finally, predictions of the model are presented with a comparison to data experimentally obtained by other researchers.

Abstract:
The contamination of sterile pharmaceutical products is a serious event which has in the worst case scenario led to patient death. Operators are the primary source of clean room contamination, with the majority of their detritus being identified as skin squames and their related microorganisms. The ability of operator associated bacterial contamination to disseminate through specialist garments worn in the clean room environment is apparent in the literature. However, despite the fibres of such garments being identified as a suitable substrate for bacteria to adhere to and grow upon, the bacterial bioburden of the surface of clean room operators’ garments is an area which severely lacks in published research. Reported here is the recovery, enumeration and comparison of the levels of bacteria on the surface of reusable antistatic carbon filament polyester clean room garments, using the direct agar contact method, following their laundering with and without terminal gamma sterilisation, immediately following their donning with operators dressing wearing either no gloves, non – sterile gloves or sterile clean room gloves, and following their wear within the clean room environment, with respect to gender. The aforementioned method, with its recovery efficiency shown to be unaffected by agar composition (NA or TSA), recovered bacteria from the surface of garments laundered with and without gamma sterilisation. Such terminal decontamination was shown to reduce the surface bacterial bioburden of the garments, especially at the chest and umbilicus regions, which were shown to harbour higher levels of bacteria than the other sites tested. The direct agar contact method, showing an increase in recovery efficiency following a 48 hour agar incubation period as opposed to a 24 hour period, also recovered bacteria from the surface of clean room garments donned by operators dressing wearing either no gloves, non – sterile gloves and sterile clean room gloves. Bacteria were transferred onto the surface of these garments via the hand borne route, with the chest and oral cavity regions being found to harbour more bacteria than the other sites tested. Overall, glove type was shown to have no effect upon the resultant bacterial bioburden of the surface of the garments, suggesting expensive clean room gloves could be substituted for their cheaper non – sterile equivalents or no gloves during the donning process without subsequently increasing the surface bacterial bioburden of the garment. The direct agar contact method also recovered bacteria from the surface of clean room garments worn by male and female operators, following their working period within a clean room environment. Gender was found to significantly affect the surface bacterial bioburden of the garments, with the surface of those garments worn by male operators being more contaminated than the surface of those worn by their female counterparts. In addition, the donning of a clean room hood was shown to reduce the levels of bacteria at the chest and posterior cervicis regions of suits worn by both genders. Overall, the direct agar contact method was identified as a successful tool to recover, enumerate and estimate the surface bacterial bioburden of reusable antistatic polyester carbon filament clean room garments. Finally, using 16S rRNA gene sequencing, found to be more reliable and accurate at identifying unknown isolates than traditional phenotypic first - stage tests, which were subsequently found to misidentify > 85 % of the isolates tested, a self - selected representative number of isolates recovered from the surface of garments during the laundering and gender comparison studies were predominantly identified as skin commensal species of Staphylococcus and Micrococcus, as well as environmental species of Bacillus. The knowledge contained within this thesis, with respect to clean room operators and their specialist garments, contributes towards improving contamination control standards within clean room facilities.

Abstract:
Låssystem kan minska risken för inbrott och stöld, och vara ett verktyg för behöriga personer att få tillgång till lokaler och rum. Därför är det viktigt att moderna låssystem är pålitliga, öppnar snabbt och är säkra. Detta examensarbete undersöker om CAN (Controller Area Network) är ett idealt kommunikationsprotokoll för ett säkerhetssystem av dörrlås, med syftet att utföra en fallstudie av CAN-protokollet. Detta sker genom att analysera ett låssystem från ASSA vars kommunikationsprotokoll mellan styroch låsenhet misstänktes använda CAN-protokollet mellan dess styrenhet och låsenhet. Slutsatsen av analysen var att låssystemet från ASSA inte kommunicerade via CAN. För att bevisa dettaåterskapades signaler med elektriska standardinterface RS-485. Det sista steget vara att utveckla ett eget låssystem med CAN som kommunikationsprotokoll, och sedan skulle de två låssystem jämföras. För att testa detta programmeras två kretskort av typen ESP32-PoE till en styrenhet och en låsenhet. Ett låssystem designades på ett kopplingsdäck innan den ersattes av två PCBs. Slutresultatet var ett motorlås och en styrenhet som konstruerades och validerades i ett kopplingsdäck. Av de två kretskorten som utvecklades fungerade kontrollenheten som förväntat, medan låsenheten hade problem med dess motor. Den kunde dock klara av dess andra uppgifter som att läsa signaler från styrenheten via en 10 meter kabel och läsa signaler från dess dörrläge givande magnetsensor. Det demonterade låssystemet sänder signaler snabbare, och öppnar låset ungefär lika snabbt, men är inte lika säker som den kommersiella låssystemet för att CAN har restriktiva säkerhetsåtgärder.
Lock systems can reduce the risk of burglary and theft, and be a tool for authorized persons to access premises and rooms. Therefore, it is important that modern lock systems are secure, reliable and open quickly. This thesis investigates whether CAN (Controller Area Network) is an ideal communication protocol for a door lock security system. This is done by analyzing a mechanical lock system from ASSA which was suspected of using CANbus as a communication protocol between the control unit and lock unit. Then the lock and control units were analyzed. The conclusion of the analysis is that the lock system did not communicate via CAN. To prove this, signals were re-created with the electrical standard interface RS-485.The final step was to construct a lock system with CAN as a communication protocol, and then the two lock systems would be compared.To test this, two ESP32-PoE development boards are programmed into a controller and a locking device. A mechanical door lock system was designed on a breadboard before being replaced by two PCBs. Of the two circuit types that were developed, the control unit worked as expected, while the motorlock unit had problems with it’s motor. However, it was able to handle its other tasks such as reading signals from the controller via a 10 meter cable and reading signals from its door locating magnetic sensor. The disassembled lock system sends signals faster, and opens the lock approximately as quickly, but is not as secure as the commercial CAN lock system has restrictive security measures.

Resumo: O objetivo desta pesquisa consistiu na adaptação e avaliação do desempenho de um sistema asséptico piloto para leite fluido em garrafa plástica. O sistema foi avaliado através da identificação e monitoração sistemática de pontos de controle do processo, testes de esterilidade comercial, análises sensorial e físico-química do produto e avaliação da embalagem. Os pontos de controle foram monitorados antes e simultaneamente aos processamentos, a saber: tratamento térmico do leite; conformidade operacional da sala de envase, incluindo pressurização, taxa de movimentação de ar, contagem de partículas totais e microrganismos no ar e avaliação de limpeza e sanificação de superfícies; análise microbiológica da água de enxágüe da linha de processamento e envase, análise das embalagens e de sua água de enxágüe. Quatro lotes de 150L de leite com pH próximo a 6,7 foram processados entre 135 a 144ºC durante 10s em um trocador de calor a placas e acondicionados assepticamente em garrafas de polietileno de alta densidade (PEAD) de 500mL, em uma sala limpa ISO classe 7. A assepsia das embalagens foi feita através de aspersão de uma mistura contendo 0,5% de ácido peracético e 0,8% de peróxido de hidrogênio a 30ºC/10s. O leite processado através do sistema asséptico piloto avaliado foi comparado ao leite longa vida comercial em embalagens cartonadas e em garrafas plásticas de PEAD de alta barreira, aplicando-se testes de aceitação sensorial. Os resultados da avaliação dos pontos de controle do processo indicaram um bom desempenho apresentado pelo sistema desenvolvido, justificado pelas baixas contagens ou ausência de microrganismos nos pontos avaliados. Dos 4 lotes processados, 2 atingiram a esterilidade comercial, baseado nos critérios físico-químicos e microbiológicos adotados. A vida útil do produto, estimada através de testes sensoriais, atingiu 4 semanas para os dois primeiros lotes produzidos, 8 semanas para o lote 3 e 11 semanas para o lote 4. A opacidade das embalagens utilizadas na pesquisa foi de 90%, inferior a opacidade das embalagens comerciais, que foi de 100%. Portanto, a barreira à luz foi considerada insuficiente para a embalagem em avaliação, em virtude da elevada sensibilidade do leite à fotoxidação. Concluiu-se que o sistema asséptico piloto avaliado correspondeu às expectativas de desempenho, devendo, entretanto, ser submetido à implementação de melhorias em sua infra-estrutura para que possa ser eventualmente disponibilizado para processamentos em pequena escala, visando a produção de leite comercialmente estéril acondicionado em garrafas plásticas
Abstract: The objective of this research was the adaptation and performance evaluation of a pilot aseptic system for liquid milk filled into plastic bottles. The system was evaluated by identifying and systematically monitoring the process control points, by commercial sterility tests, sensory, physical and chemical analyses of the product and an evaluation of the packaging. The control points were monitored before and during process as follows: heat treatment of the milk; operational conformity during filling in the aseptic room including pressurization, air movement rate, total and viable particle count and evaluation of surface cleanliness and sanitation; microbiological analyses of the rinsing waters used in the process and filling lines and an analysis of the packages and their rinsing water. Four 150L batches of milk with pH values of about 6.7 were heat processed between 135 and 144°C for 10s in a plate heat exchanger and filled aseptically into 500mL high density polyethylene (HDPE) bottles in an ISO class 7 clean room. The aseptic condition of the bottles was obtained by spraying with a mixture containing 0.5% peracetic acid and 0.8% hydrogen peroxide for 10s at 30°C. The processed milk using the pilot aseptic system was compared by sensory analysis with commercial long life milk filled into carton-type packages and plastic bottles. The results of the microbial evaluation of the control points indicated good performance of the system developed based on the low counts and absence of microorganisms at some evaluated points. Of the 4 batches processed, 2 attained commercial sterility based on the physical-chemical and microbiological criteria adopted. The shelf life of the product, estimated according to the sensory tests, was 4 weeks for the first two batches processed, 8 for batch 3 and 11 for batch 4. The opacity of the packaging used was 90%, lower than that of commercial packaging, which was 100%. Thus the light barrier property was considered inadequate considering the high sensitivity of milk to the photooxidation. It was concluded that the pilot aseptic system evaluated corresponded to the performance expectations, however, it should be submitted to some implementations of improvements in its infrastructure in order to be recommended for small-scale commercially ile milk production

Abstract:
As indústrias farmacêuticas que utilizam salas limpas, em seus processos produtivos, devem controlar ao máximo o nível de contaminantes microbiológicos, baseada na legislação RDC 210 que determina o cumprimento das diretrizes estabelecidas no Regulamento Técnico das Boas Práticas para a Fabricação de Medicamentos. Diante deste cenário, a proposta deste trabalho é avaliar o processo de fumigação com o reagente formaldeído, para a limpeza e desinfecção de salas limpas do Instituto de Tecnologia de Imunobiológicos Bio-Manguinhos. Então, foram desenvolvidas as seguintes etapas: diagnóstico com as indústrias farmacêuticas para traçar um perfil quanto ao uso da fumigação; quantificação de resíduos gerados; avaliação da exposição dos operadores ao formaldeído que é cancerígeno e acompanhamento dos resultados do monitoramento ambiental do ar e de superfícies, inicialmente na sala limpa do SEFBC, cuja atividade principal é a formulação de vacinas bacterianas e biofármacos, após a implantação do espaçamento da fumigação. Os resultados discutidos na presente dissertação mostraram, que a maior parte das indústrias farmacêuticas, não realiza a desinfecção por intermédio da fumigação e que o resíduo gerado neste processo é o mais crítico. E, sobretudo, o monitoramento microbiológico do ar e de superfícies da sala limpa do SEFBC, a partir da metodologia adotada de espaçamento da fumigação, comprovou que não é necessário o emprego deste processo de forma rotineira, para garantir os níveis exigidos de limpeza e desinfecção da respectiva área
Pharmaceutical industries that use clean rooms for their productive processes, must control to a maximum the level of microbiological contaminants, based on RDC 210 legislation that determines the fulfillment of lines in the directions established by the Technical Regulation Program for a Good Medicine Manufacturing. Ahead to this scene, the purpose of this work was to evaluate the process of fumigation with reacting formaldehyde, for the cleanness and disinfection of clean rooms of the Bio-Manguinhos Institute of Technology of Imunobiológicos. Then, the following stages had been developed: diagnosis with the pharmaceutical industries in order to get a scenario on the use of fumigation; quantification of the residues generated; evaluation of the exposition of operators to formaldehyde, a cancerigenous agent, and screening of the results of the environment monitoring of the air and surfaces, initially in the clean room of the SEFBC, in the areas of biopharmaceuticals formulation, and after a proper implementation of a fumigation process, at pre-defined intervals. The results thus obtained showed that most of the pharmaceutical industries no longer use disinfection for fumigation and that the residues generated in this process is the most critical problem. The overall microbiological monitoring of the air and surfaces of SEFBC clean room, according to the proposed methodology for fumigation, proved that the use of this process as a routine is not essential to guarantee the demanded levels of cleanness and disinfection of the respective areas

Full text
Abstract:
Specific Objectives and Related Results: 1) Determine the effect of phosphorus availability on ethylene production by roots. Test the hypothesis that phosphorus availability regulates ethylene production Clear differences were found between the two plants that were studied. In beans ethylene production is affected by P nutrition, tissue type, and stage of development. There are genotypic differences in the rate of ethylene production by various root types and in the differential in ethylene production when P treatments are compared. The acceleration in ethylene production with P deficiency increases with time. These findings support the hypothesis that ethylene production may be enhanced by phosphorus deficiency, and that the degree of enhancement varies with genotype. In tomatoes the low-P level did not enhance significantly ethylene production by the roots. Wildtype cultivars and ethylene insensitive mutants behaved similarly in that respect. 2) Characterize the effects of phosphorus availability and ethylene on the architecture of whole root systems. Test the hypothesis that both ethylene and low phosphorus availability modify root architecture. In common bean, the basal roots give rise to a major fraction of the whole root system. Unlike other laterals these roots respond to gravitropic stimulation. Their growth angle determines the proportion of the root length in the shallow layers of the soil. A correlation between ethylene production and basal root angle was found in shallow rooted but not deep-rooted genotypes, indicating that acceleration of ethylene synthesis may account for the change in basal root angle in genotypes demonstrating a plastic response to P availability. Short-time gravitropic response of the tap roots of young bean seedlings was not affected by P level in the nutrient solution. Low phosphorus specifically increases root hair length and root hair density in Arabidopsis. We tested 7 different mutants in ethylene perception and response and in each case, the response to low P was lower than that of the wild-type. The extent of reduction in P response varied among the mutants, but every mutant retained some responsiveness to changes in P concentration. The increase in root hair density was due to the increase in the number of trichoblast cell files under low P and was not mediated by ethylene. Low P did not increase the number of root hairs forming from atrichoblasts. This is in contrast to ethylene treatment, which increased the number of root hairs partly by causing root hairs to form on atrichoblasts. 3) Assess the adaptive value of root architectural plasticity in response to phosphorus availability. A simulation study indicated that genetic variation for root architecture in common bean may be related to adaptation to diverse competitive environments. The fractal dimension of tomato root system was directly correlated with P level.

Abstract:
Attic fires pose many hazards for the fire service. When a fire occurs in an attic, it is common it goes unnoticed/reported until smoke or flames are visible from the outside of the structure. Because they take longer to detect, attic fires are more dangerous for firefighters and residents. In a fire situation, the attic ventilation system, which is designed to reduce moisture accumulation by drawing fresh air low from the eaves and exhausting moisture laden warm air near the peak, create an optimal fire growth and spread situation by supplying oxygen to the fire and exhausting hot gases. An estimated 10,000 residential attic fires are reported to U.S. fire departments each year and cause an estimated 30 civilian deaths, 125 civilian injuries and $477 million in property loss. The location of the attic creates several difficulties for the fire service. Firefighters must decide whether to fight the fire from inside the structure, from the outside or a combination of the two. This the decision is complicated by the constant hazard of ceiling collapse, which has the potential to rapidly deteriorate conditions in the living spaces. A piece of gypsum board may fall or be pulled from the ceiling making the relatively clear and cool conditions in the living space change very quickly endangering firefighters executing a search and rescue operation as part of their life safety mission. Further complicating the decision are the hazards associated with roof structure collapse, creating deadly conditions for firefighters operating on and under the roof. Structural collapse accounted for 180 firefighter deaths between 1979 and 2002 of which one-third occurred in residential structures . Many of these incidents involved a roof falling on firefighters or firefighters falling through the roof during firefighting operations on attic fires. The purpose of this study is to increase firefighter safety by providing the fire service with scientific knowledge on the dynamics of attic and exterior fires and the influence of coordinated fire mitigation tactics from full-scale fire testing in realistic residential structures.

Abstract:
The objectives of this project were to predict the performance of naturally and fan-ventilated greenhouses as a function of climate, type of crop, evaporative cooling and greenhouse size, and to estimate the effects of the two cooling systems on yield, quality and disease development in the different crops under study. Background In the competitive field of greenhouse cultivation, growers and designers in both the US and Israel are repeatedly forced to choose between naturally ventilated (NV) and fan ventilated (FV) cooling systems as they expand their ranges in an effort to remain profitable. The known advantages and disadvantages of each system do not presently allow a clear decision. Whether essentially zero operating costs can offset the less dependable cooling of natural ventilation systems is question this report hopes to answer. Major Conclusions US It was concluded very early on that FV greenhouses without evaporative pad cooling are not competitive with NV greenhouses during hot weather. During the first year, the US team found that average air temperatures were always higher in the FV houses, compared to the NV houses, when evaporative pad cooling was not used, regardless of ventilation rate in the FV houses or the vent configuration in the NV houses. Canopy temperatures were also higher in the FV ventilated houses when three vents were used in the NV houses. A second major conclusion was that the US team found that low pressure fogging (4 atm) in NV houses does not completely offset the advantage of evaporative pad cooling in FV houses. High pressure fog (65 atm) is more effective, but considerably more expensive. Israel Experiments were done with roses in the years 2003-2005 and with tomatoes in 2005. Three modes of natural ventilation (roof, side and side + roof openings) were compared with a fan-ventilated (with evaporative cooling) house. It was shown that under common practice of fan ventilation, during summer, the ventilation rate is usually lower with NV than with FV. The microclimate under both NV and FV was not homogeneous. In both treatments there were strong gradients in temperature and humidity in the vertical direction. In addition, there were gradients that developed in horizontal planes in a direction parallel to the direction of the prevailing air velocity within the greenhouse. The gradients in the horizontal direction appear to be larger with FV than with NV. The ratio between sensible and latent heat fluxes (Bowen ratio) was found to be dependent considerably on whether NV or FV is applied. This ratio was generally negative in the naturally ventilated house (about -0.14) and positive in the fan ventilated one (about 0.19). Theoretical models based on Penman-Monteith equation were used to predict the interior air and crop temperatures and the transpiration rate with NV. Good agreement between the model and experimental results was obtained with regard to the air temperature and transpiration with side and side + roof ventilation. However, the agreement was poor with only roof ventilation. The yield (number of rose stems longer than 40 cm) was higher with FV
