Resumen

Background. To determine the prognostic significance of pretreatment levels of circulating lymphocyte (CLC), neutrophil (CNC), and monocyte (CMC) counts in patients with locally advanced cervical carcinoma (CC) treated with definitive radiation.Methods. A retrospective, dual-institution review of patients with Stage IB2-IVA CC from 2005 to 2015. Progression-free (PFS) and Overall Survival (OS) were determined for high and low CLC, CNC, and CMC groups. Multivariate analysis was used to confirm prognostic value of baseline leukocyte counts.Results. 181 patients were included. Median follow-up time was 26 (3–89) months. CNC had no effect on PFS or OS. PFS was similar between CMC groups; however, OS was significantly improved for patients with low CMC (62.5 versus 45.3 months,p=0.016). High CLC was associated with improved PFS (48.5 versus 27.8 months,p=0.048) and OS (58.4 versus 34.9 months,p=0.048). On multivariate analysis, high CNC was associated with increased relapse risk (HR 1.12,p=0.006) and low CLC was associated with increased mortality risk (HR 0.67,p=0.027).Conclusion. This study demonstrates that leukocyte values can provide prognostic information in CC. These hypothesis-generating findings warrant further prospective investigations.

Resumen

Biobased materials present a great interest due to their properties and biodegradability. Cellulose nanocrystals (CNC) nanofiller, in various amounts, was incorporated into a carboxymethyl cellulose (CMC)–glycerol (G) matrix in order to obtain nanocomposite systems with improved properties. The effect of the nanofiller on the structural features was investigated by Fourier transform infrared (FT-IR) spectroscopy, principal component analysis (PCA), two-dimensional correlation spectroscopy (2D-COS), and X-ray diffraction, while the sorption properties were evaluated by water vapor isotherms using the gravimetric method coupled with infrared spectroscopy. We observed the presence of the interactions taking place between the CMC-G and CNC involving the hydroxyl and carboxylate groups, which decreased the number of water sorption sites. Following this, the moisture content in the nanocomposite films decreased with the increase in the amount of CNC. Moreover, the bands associated to water molecules presented different wavenumber values separated for CMC-G and CNC components.

Resumen

In recent years, the development of cellulose-based inks for 3D printing has received significant interest due to numerous cellulose and its derivatives properties [1], [2]. Carboxymethyl cellulose (CMC) is an anionic water-soluble cellulose derivative widely used as superabsorbent hydrogels [3]. Another cellulose derivative is cellulose nanocrystal (CNC), a rod-like nanoparticle that can be applied for the mechanical strengthening of hydrogels and also presents potential use in several applications in the biomedical field [2], [4]. Based on this, we have proposed to investigate if CMC and CNC mixtures result in cellulose-based nanocomposite gels suitable for extrusion printing of wearable sensors. Interactions between CNC and CMC resulted in physical gels, where rheological properties and extrusion printing parameters' effects were studied. A Modular Compact Rheometer (Anton Paar MCR-102, Austria) with a plate-plate geometry (50 mm diameter and 1 mm gap) at 25 °C was used to perform rheological measurements. Extrusion printing was performed on the customized 3DCloner Lab printer using a 22G nozzle tip of 25 mm in length and a diameter of 0.70 mm (Injex, Brazil). Gels presented shear-thinning, solid-like viscoelastic behavior, viscosity recovery, and continuous filaments obtained during printing. Moreover, the alignment of rod-like CNC during the printing process can be a key to improving properties. Tests with different print and extrusion speeds evidenced the influence of the wearable sensor's geometry and mechanical properties. Moreover, the low cytotoxicity of CMC/CNC crosslinked hydrogels was confirmed through an MTT assay of fibroblasts. Further testing is being conducted to evaluate the self-healing and conductive properties of the sensors by external stimuli. Moreover, low cytotoxicity to CMC/CNC crosslinked hydrogels was confirmed through an MTT assay of fibroblasts. External stimuli are being applied to evaluate the self-healing and conductive of the sensor printed.

Resumen

Guanidine-based surfactant ethyl lauroyl arginate (LAE) and cellulose nanocrystals (CNCs) form complexes of enhanced surface activity when compared to pure surfactants. The LAE-CNC mixtures show enhanced foaming properties. The dynamic thin-film balance technique (DTFB) was used to study the morphology, drainage and rupture of LAE-CNC thin liquid films under constant driving pressure. A total of three concentrations of surfactant and the corresponding mixtures of LAE with sulfated (sCNC) and carboxylated (cCNC) cellulose nanocrystals were studied. The sCNC and cCNC suspension with LAE formed thin films, with stability increasing with surfactant concentration and with complex rheological properties. In the presence of LAE, the aggregation of CNC was observed. While the sCNC aggregates were preferentially present in the film volume with a small fraction at the surface, the cCNC aggregates, due to their higher hydrophobicity, were preferentially located at film interfaces, forming compact layers. The presence of both types of aggregates decreased the stability of the thin liquid film compared to the one for the LAE solution with the same concentration. The addition of CNC to LAE was critical for foam formation, and foam stability was in qualitative agreement with the thin films’ lifetimes. The foam volume increased with the LAE concentration. However, there was an optimum surfactant concentration to achieve stable foam. In particular, the very resistant foam was obtained with cCNC suspensions that formed the interfaces with a complex structure and rheology. On the other hand, at high LAE concentrations, the aggregates of CNC may exhibit antifoaming properties

Resumen

A programming to make parts are CNC Programming (Computer Numerical Control Programming) for machines. An NC program consists of a sequence of instructions that control the motion and automatic sequences of an NC Machine to perform a particular processing task. In a general sense, the term NC programming refers to the creation of control data for machining workpieces on NC and CNC machines. NC programming has a decisive influence on the cost-effectiveness and profitability of NC manufacturing. The selection of a programming system is mostly guided by the need for software that is suitable for the application at hand, readily available, and as universally applicable as possible.

Resumen

Este artigo consiste em uma revisão bibliográfica, que tem como intuito apresentar o torno CNC (comando numérico computadorizado) sua evolução, características e implicações no setor de usinagem. Ao longo do trabalho será discorrido, sobre a criação do mesmo, rudimentares a princípio onde as operações baseavam-se na habilidade do torneiro. À medida que a humanidade evolui no quesito tecnológico, e pela necessidade de se adequar à nova realidade frente ao mundo globalizado surgiu o torno com comando numérico computadorizado. Importante ferramenta no processo fabril no setor de usinagem, devido à alta precisão com que realiza o torneamento e dimensionamentos de peças complexas com menores incidências de erros, perda de tempo e dinheiro ao longo do processo, cumprimento de prazos e qualidade dos produtos de acordo com as exigências dos clientes. Tais fatores contribuem para que o setor de usinagem, importante atividade, considerada um dos processos de fabricação mais popular no mundo se tornem competitivo mediante a concorrência. No geral as pesquisas comprovaram a eficiência do torno CNC contudo, tem que considerar o tipo de empresa e produção, relacionando o custo benefício como proposta futura que haja maior interesse em novas publicações acerca do referido assunto.

Resumen

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.
Includes bibliographical references.
A large-format CNC router has been stored in the Pappalardo Laboratory wood shop for several years in an unusable state. A need assessment determined that it would be cost effective to bring the router online for use in the mechanical engineering curriculum. The router was cleaned and inspected; it was determined that the router was in sound mechanical condition. The stepper motors, control system, and power supply were also functional, but the CNC interface software was outdated. To ensure the long term viability of the router as an effective teaching tool the most cost effective solution was to upgrade the motors, control system, and CNC interface software using a package provided by the original supplier, Techno-Isel Inc. The motors, control system, and software were installed, bringing the router to a fully functional state. Dust and ejected cuttings cause a safety hazard and cleanliness problem when operating the router. An enclosure was designed and installed in order to trap the majority of debris and reduce noise levels in the workspace, and a brief user guide has been compiled to ensure safe and effective usage.

Resumen

Cellulose nanocrystal (CNCs) assisted carbon nanotubes (CNTs) and graphene nanoplatelets (GnP) were used to modify the interfacial region of carbon fiber (CF) and polymer matrix to strengthen the properties of carbon fiber-reinforced polymer (CFRP). Before transferring CNC-CNTs and CNC-GnPs on the CF surface by an immersion coating method, the nanomaterials were dispersed in DI water homogeneously by using probe sonication technique without additives. The results showed that the addition of CNC-CNT and CNC-GnP adjusted the interfacial chemistry of CFRP with the formation of polar groups. Furthermore, according to the single fiber fragmentation test (SFFT), the interfacial shear strength (IFSS) of CNC-GnP 6:1 and CNC-CNT 10:1 added CFRP increased to 55 MPa and 64 MPa due to modified interfacial chemistry by the incorporation of the nanomaterials. This processing technique also resulted in improvement in interlaminar shear strength (ILSS) in CFRPs from 35 MPa (neat composite) to 45 (CNC-GnP 6:1) MPa and 52 MPa (CNC-CNT 10:1).

Resumen

Closed Loop manufacturing describes the use of feedback from a Computer Numerical Control (CNC) to the Enterprise Resource Planning (ERP) to help in business operations. Although conceptually simple, many obstacles make CNC-ERP connectivity difficult — incompatibilities of various generations of systems supplied by multiple vendors, differing personnel mindsets and objectives, and outright complexity of ERP. A long journey starts with a single step, and this paper describes a successful pilot project that detected scrap on a CNC during production of the Boeing 737 Leading Edge panels and then automatically entered a scrap reorder into the ERP Supply Chain Management (SCM) Reorder System. The pilot leveraged three major technologies, including open-architecture CNC, OLE for Process Control (OPC) integration technology, and supply chain Web Services. Overall, the pilot project successfully established that integration of CNC into SCM can be straightforward as we automated 90% of one manual step within the scrap Supply Chain Reorder process to impart a leaner manufacturing operation.

Resumen

Although current rapid prototyping methods have had a significant impact on product and process design, they are often limited in both accuracy and choice of suitable materials. Also, the current methods share little similarity to typical manufacturing processes. In this paper, a method for using CNC machining as a Rapid Prototyping process is described in order to exploit the creation of functional prototypes in a wide array of materials. The method uses a plurality of simple 2 1/2-D toolpaths from various orientations about an axis of rotation, in order to machine the entire surface of a part without refixturing. It is our goal to automatically create these tool paths for machining, and eliminate the complex planning traditionally associated with CNC machining. The current approach to process planning involves calculating all the necessary data from the slice information of an STL model. An overview of the CNC-RP process and the process planning methodology is presented.

Resumen

The Eco-Digital Fabrication (EDFAB) research project aimed to investigate how automated prefabrication technologies and off-the-shelf construction products can be employed to disrupt building industry norms. The aim of this research – conducted at the University of Auckland and Unitec Institute of Technology from 2014 onward – was to provide small-to-medium enterprises in the construction industry with a pathway to upskill and increase construction productivity through the use of these processes. The availability of automated machines and easy-to-use fabrication software is increasing dramatically and this can be paired with readily available construction products to produce novel mass-customised housing solutions. The application of basic automated technologies – such as CNC (Computer Numerical Control) routers – allowed researchers to create ‘recipes’ that can be adopted and adapted relatively easily. By no means did the research favour digital manufacture or assembly processes over traditional analogue construction techniques – the goal was to provide logical, productive and accessible blended solutions for greater affordability and flexibility in design. For example, the designed experiments were required to be built from readily available products, and used simple readymade screw fixings rather than digitally produced custom fixings or joining mechanisms. The research project aimed to generate discussion and provide recommendations on how the construction industry might support the adoption of automated prefabrication technology in small-to-medium enterprise (SME).
