Avaliação dos aspectos dosimétricos no tratamento de câncer de tireóide com Iodo-131

The 131I (radioactive iodine) is one of the most used radionuclides in nuclear medicine for diagnosis and treatment. The present study evaluates the dosimetric aspects related to radioiodine therapy after thyroidectomy in patients with thyroid cancer. The samples were studied with 50 patients undergoing treatment, by assessing the exposures of workers (nursing assistants, staff hygiene, medical and physical), the general public (accompanying and family members) and on the environment. To evaluate the workers, was made a survey of the environmental conditions of the room radioiodine and routines adopted by them during the treatment period. Estimating the dose equivalent per month for each employee, we observed that the maximum levels obtained for nursing assistants, the team of hygiene, medical and physicians were considered low in relation to the extent permitted by law. In order to assess the public, some situations have been suggested for the calculation of equivalent doses in which it was possible to verify the fundamental importance of isolating the patient in the 2 days first. Regarding the environment, the radioactive waste generated by patient had volume of 1.0 m3 and activity estimated at 0.91 mCi, taking a decay time for eliminating them about 75 days to reach the allowable value of 2 μCi / kg system of collecting garbage. Therefore, all radioactive waste removed from the patient's room should be sent to the warehouse for temporary storage of radioactive waste, located away from normal work areas

Dimensionamento de estoques de materiais elétricos em centros de distribuição

Due to the high level of service required by customers and the constant need to reduce costs, the logistics can be considered as a strategic area for a company. In particular, the order picking is responsible for most of the operating costs in a warehouse. Therefore it’s necessary to plan the materials storage in order to maximize the space available and minimize the total distance traveled to meet customer orders. For these reasons, this study aims to examine and propose a way to organize the electrical materials storage in distribution centers through a study on an electronics company in Cajamar

Analysis of simple hardware efficiency for temperature measurement in agriculture and environment

This work focuses basically on the design and analysis of simple and low cost hardware systems efficiency for temperature measurement in agricultural area. The main objective is to prove quantitatively, through statistical data analysis, to what extent a simple hardware designed with inexpensive components can be used safely in the indoor temperature measurement in farm buildings, such as greenhouses, warehouse or silos. To verify the of simple hardware efficiency, its data were compared with data from measurements with a high performance LabVIEW platform. This work proved that a simple hardware based on a microcontroller and the LM35 sensor can perform well. It presented a good accuracy but a relatively low precision that can be improved when performed some consecutive signal sampling and then used its average value. Although there are many papers that explain these components, this work has the distinction of presenting a data analysis in numerical form and using high performance systems to ensure critical data comparison.

A METHODOLOGY TO EVALUATE OBSOLETE INVENTORY IN HEALTH CARE

Many organizations are currently facing inventory management problems such as distributing inventory on-time and maintain the correct inventory levels to satisfy the customer or end users. Organizations understand the need for maintaining the accurate inventory levels but sometimes fall short leading a wide performance gap in maintaining inventory accurately. The inventory inaccuracy can consume much of the investment on purchasing inventory and many times leads to excessive inventory. The research objective of thesis is to provide a decision making criteria to the management for closing or maintaining the warehouse based on basic purchasing and holding cost information. The specific objectives provide information regarding the impact of inventory carrying cost, obsolete inventory, inventory turns. The methodology section explains about the carrying cost ratio that would help inventory managers to adopt best practices to avoid obsolete inventory and also reduce excessive inventory levels. The research model was helpful in providing a decision making criteria based on the performance metric developed. This research model and performance metric had been validated by analysis of warehouse data and results indicated a shift from two-echelon inventory supply chain to a one-echelon or Just In Time (JIT) based inventory supply chain. The recommendations from the case study were used by a health care organization to reorganize the supply chain resulting in the reduction of excessive inventory.

COMPLETE CONTROL OF NUISANCE BIRDS IN AIRPORT HANGARS

Fogging of ReJeX-iT7 TP-40 offers a very efficient method for the control and dispersal of nuisance birds from many diverse areas. The amount of the repellent is greatly reduced over any other control method. The method is direct and is independent of the activity of the birds. The applications with any fogger, thermal or mechanical, that can deliver droplets of less than 20 microns, can be manually or fully automated and pose only minimal risks to operators or animals. All birds that became a nuisance and safety problem in the hangars of TWA and AA at LaGuardia, and TWA warehouse at Newark Airport were successfully driven out by fogging ReJeX-iT7 TP-40 with a Curtis Dyna-Fog AGolden Eagle@ thermal fogger.

The SB-index and the HSB-index: efficient indices for spatial data warehouses

Spatial data warehouses (SDWs) allow for spatial analysis together with analytical multidimensional queries over huge volumes of data. The challenge is to retrieve data related to ad hoc spatial query windows according to spatial predicates, avoiding the high cost of joining large tables. Therefore, mechanisms to provide efficient query processing over SDWs are essential. In this paper, we propose two efficient indices for SDW: the SB-index and the HSB-index. The proposed indices share the following characteristics. They enable multidimensional queries with spatial predicate for SDW and also support predefined spatial hierarchies. Furthermore, they compute the spatial predicate and transform it into a conventional one, which can be evaluated together with other conventional predicates by accessing a star-join Bitmap index. While the SB-index has a sequential data structure, the HSB-index uses a hierarchical data structure to enable spatial objects clustering and a specialized buffer-pool to decrease the number of disk accesses. The advantages of the SB-index and the HSB-index over the DBMS resources for SDW indexing (i.e. star-join computation and materialized views) were investigated through performance tests, which issued roll-up operations extended with containment and intersection range queries. The performance results showed that improvements ranged from 68% up to 99% over both the star-join computation and the materialized view. Furthermore, the proposed indices proved to be very compact, adding only less than 1% to the storage requirements. Therefore, both the SB-index and the HSB-index are excellent choices for SDW indexing. Choosing between the SB-index and the HSB-index mainly depends on the query selectivity of spatial predicates. While low query selectivity benefits the HSB-index, the SB-index provides better performance for higher query selectivity.

Dalla normativa alle procedure perative:gestione dei dati ai fini della prevenzione e protezione in un'azienda multiservizi

La presente Tesi di Laurea Specialistica considera, partendo da un'analisi della normativa vigente e delle procedure aziendali interne, il Sistema di Gestione Integrato Qualità  Sicurezza Ambiente (SGI QSA) di HERA SpA con particolare attenzione alle tematiche relative alla Prevenzione e Protezione sul luogo di lavoro in riferimento al Testo Unico sulla sicurezza (D.Lgs 81/2008) . Nello specifico, l'elaborato si basa sull'esperienza maturata durante cinque mesi di stage effettuati presso l'ufficio "Servizio Prevenzione e Protezione" della Struttura Operativa Territoriale (SOT) Bologna. Durante la mia permanenza in HERA SpA, ho avuto modo di osservare e prendere parte alle attività  quotidianamente svolte sia in ufficio che presso gli impianti dislocati nel territorio della provincia di Bologna con particolare riguardo alla raccolta, gestione e fruibilità  dei dai inerenti la sicurezza dei luoghi di lavoro. Nell'ambito dello stage, ho avuto anche la possibilità , estremamente formativa, di prendere visione dei processi, delle tecnologie e delle modalità  operative sottostanti l'erogazione di servizi da parte di una Multiutility; acquisire consapevolezza e know how in merito alle energie messe in campo per effettuare attività  quali la raccolta e lo smaltimento di rifiuti piuttosto che rendere disponibile alle utenze la fornitura di acqua e gas. Ritengo che questo possa darmi un valore aggiunto sia da un punto di vista professionale che da un punto di vista umano. Scopo primario di questa trattazione è effettuare l'istantanea di un'azienda complessa e in rapida evoluzione come HERA a partire della Salute e Sicurezza dei Lavoratori con l'obiettivo di indicare le attività  eseguite durante lo stage e il contributo fornito allo sviluppo e al mantenimento del SGS (Sistema di Gestione per la Salute e la sicurezza). Per meglio evidenziare la diversa natura delle informazioni riportate, l'elaborato risulta diviso in due parti fondamentali: La I PARTE riguarda lo studio della normativa che regola il settore con particolare riferimento al TUSL Testo Unico per la Sicurezza sui Luoghi di Lavoro (norma vigente in Italia) e allo standard britannico OHSAS 18001 a cui possono fare riferimento le organizzazioni che intendono certificare il proprio sistema di gestione in materia di sicurezza. In seguito si andranno ad analizzare le norme ISO 9001e ISO14001 che riguardano rispettivamente la possibilità  di certificare il proprio sistema di gestione in merito a Qualità  del servizio e tutela dell'Ambiente. Infine saranno proposte alcune riflessioni riguardanti la necessità  di sviluppare un sistema di gestione integrato e certificato che permetta di avere una visione unitaria di Qualità  Sicurezza e Ambiente. Nella II PARTE si entrerà  nel merito delle attività  svolte dall'ufficio Prevenzione e Protezione: a partire dalle procedure aziendali che fungono da punto di contatto fra gli obblighi normativi e la necessità  di regolare l'operatività  dei lavoratori, saranno descritte le mansioni che mi sono state affidate e le attività  svolte durante lo stage.
