Factors to Consider in the Design of Plastic Packaging Intended for Reuse of Consumers

Most plastic packaging is used only once before they are thrown away often ending up polluting the environment. This study explores the factors to consider in designing plastic packaging to change the disposal behavior of the consumers, driving them to reuse plastic packaging. The factors considered in this study are those related to the attributes of plastic packaging, instead of factors related to the consumers as in the previous studies. Structural Equation Modelling was used to determine the significant factors that can predict the reuse behavior of consumers. Factors significant to reusing include usability, information, convenience, cost, and the future usefulness of the packaging. The top significant factors are commonly related to the simplification of the task. The findings of this study imply that plastic packaging should be designed in way that will make reusing as simple as throwing a trash away.
A STOCHASTIC DOMINANCE ANALYSIS OF ALTERNATIVE SUGAR BEET- AND NAVY BEAN- BASED CROP ROTATIONS IN MICHIGAN

Sugar beets (Beta vulgaris L.) and navy beans (Phaseoulus vulgaris L.) have been important target crops in the crop rotation systems of many Michigan growers, particularly in the Saginaw Valley and the Thumb region. The recent decline in sugar beet yields combined with the erratic navy bean yields have led to concern about the optimal crop rotation for the East Central region in Michigan. Risk is an important consideration in a farmer's choice of cropping systems. This study uses 20 years of experimental data from the Michigan State University Saginaw Valley Research Farm to determine the risk efficiency of alternative sugar beet- and navy bean- based crop rotations that included corn (Zea mays L.), oats (Avena sativa L.), and alfalfa (Medicago sativa L.) as rotational crops. The crop rotations differed in rotation length and crop sequence. Stochastic dominance analysis showed that the two-year rotation of sugar beets followed by navy beans was first-degree stochastic (FSD) and second-degree dominant (SSD) over 11 other crop rotation alternatives. Crop rotations that included sugar beets in two-year rotations and both sugar beets and navy beans in three-year rotations were the next stochastic dominant systems. Keywords: crop rotation, cropping system, risk, stochastic dominance analysis, first-degree stochastic dominance, second-degree stochastic dominance.
An Empirical Evaluation of the COTS Air Pollution Masks in a Highly Polluted Real Environment

Air pollution levels have been increasing at an alarming rate for the past few years. The concentration of particulate matter in the air in Delhi has increased by 66% in last ten years. Increased levels of pollution are causing health hazards. It is high time to sensitize people about the quality of air they are breathing in. The need of the hour is to make people aware of different methods to protect themselves from pollution. Using respiratory masks, is one of them. However, just using the respiratory mask does not solve the problem. People need to be made aware of which respiratory mask to choose and also about proper techniques of using it, to achieve optimum protection. In this paper, an analysis of three Commercial-Off-The-Shelf (COTS) N-series masks is provided. In addition to these respiratory masks, Honeywell Anti PM 2.5 and handkerchief are also included in the study, which are the low-cost substitutes. These masks are visibly available and used by a large number of people. The filtration capacity of masks is examined both in ideal condition and when wrapped around an emulated human face. To stress-test the respiratory masks, all the experiments were performed when the pollution was at the peak in a day. Results show that all the masks provide good protection against pollution when used in ideal condition, but failed to provide the same level of protection when they were used around an emulated face. The proper facial fit of the mask emerged out as an essential factor for the proper filtration of particulate matter. Moreover, durability test on masks was also performed. This test gave insight into how frequently should one replace the old used mask with a new one.
Review on concrete nanotechnology

The study of the application of nanotechnology in the construction industry and building structures is one of the most prominent priorities of the research community. The outstanding chemical and physical properties of nanomaterials enable several applications ranging from structural reinforcement to environmental pollution remediation and production of self-cleaning materials. It is known that concrete is the leading material in structural applications, where stiffness, strength and cost play a key role in the high attributes of concrete. This paper reviews the literature on the application of nanotechnology in the construction industry, more particularly in concrete production. The paper first presents general information and definitions of nanotechnology. Then, it focuses on the most effective nanoadditives that readily improve concrete properties, such as (i) nanosilica and silica fume, (ii) nanotitanium dioxide, (iii) iron oxide, (iv) chromium oxide, (v) nanoclay, (vi) CaCO3, (vii) Al2O3, (viii) carbon nanotubes and (ix) graphene oxide. Besides summarising the main nanomaterials used in concrete production as well as the results achieved with each addition, some future potential consequences of nanotechnology development and orientations to explore in construction are discussed.
Effect of Surface Texturing on the Steady-State Properties and Dynamic Coefficients of a Plain Journal Bearing: Experimental Study

The last decade has seen a significant and increased interest in surface texturing technologies esulting in improving the overall tribological properties of mechanical components. Several techniques could be used to modify the surface topography with laser surface texturing becoming most popular recently. In this investigation, rig experiments have been performed on plain and textured-surface journal bearings with an aspect ratio of 1.1 under a variety of loads and speeds. Percussive burnishing (embossing) was used to create the dimples on the internal surfaces of the test bearings. The dimples have a spherical shape with a diameter of 1 mm and a depth of 60 micrometers. Pit-area ratio was in the range 5–20% of the total bearings surfaces. The effects of surface-texturing and dimple density on the bearing steady-state characteristics and dynamic coefficients are analyzed and discussed in this paper.Copyright © 2011 by ASME and Her Majesty The Queen in Right of Canada

Flow Visualization Studies over a UCAV 1303 Model

Abstract : This study is a qualitative documentation of the main flow features over an Unmanned Combat Air Vehicle (UCAV) 1303 model by flow visualization techniques where it gives the first understanding of the UCAV maneuverability under steady and unsteady maneuver conditions. The relevant fluid flow physics is not available presently and, hence, this thesis concentrated on generating those critical details. Towards this goal, model studies were conducted on the United States Air Force (USAF) geometry, described as same UCAV 1303, which is essentially a flying wing in the Naval Postgraduate School (NPS) water tunnel using dye-flow visualization technique. This study adapted the UCAV model 1303 for the NPS water tunnel by incorporating multiple ports for dye injection and was manufactured using rapid prototyping techniques. To obtain conditionally sampled flow images, especially for unsteady flow conditions, special phase locking circuitry was designed, fabricated and integrated with high resolution digital cameras and tunnel flow monitoring software. Flow visualization images at various Reynolds numbers, model attitudes and pitch rates were obtained. Strong vortical flow was observed as expected for a 47 degree delta-wing. The shallow sweep angle and tail-less geometry seemed to present some unusual aerodynamic characteristics in regard to vortex bursting.
Path constrained time-optimal motion of a cooperative two robot system

This paper presents a systematic approach to the time-optimal motion planning of a cooperative two robot system along a prescribed path. First, the minimum-time motion planning problem is formulated in a concise form by parameterizing the dynamics of the robot system through a single variable describing the path. The constraints imposed on the input actuator torques and the exerted forces on the object are then converted into those on that variable, which result in the so-called admissible region in the phase plane of the variable. Considering the load distribution problem that is also involved in the motion, we present a systematic method to construct the admissible region by employing the orthogonal projection technique and the theory of multiple objective optimization. Especially, the effects of viscous damping and state-dependent actuator bounds are incorporated into the problem formulation so that the case where the admissible region is not simply connected can be investigated in detail. The resultant time-optimal solution specifies not only the velocity profile, but also the force assigned to each robot at each instant. <<ETX>>

A Result Paper on Experimental Study on Stabilization of Soil Subgrade by Adding Stone Dust

There are various technique for improving strength and CBR value of soil. But by this method lot of investment require. So we improved the strength of soil by adding waste slurry of stone which contain lime. We find that when Kota Stone Dust is added in the soil then optimum moisture contains will be increased from 13.80 % to 19.70 %. Because in the Kota Stone Dust lime is available so lime absorb the water it moisture contain value increased. We also conclude that when Kota Stone Dust are added in the soil then maximum dry density will be decreased 1.72 to 1.593 g/cc. We also conclude that by adding Kota Stone Dust are added in the soil then UCS will also increased from 0.213MPa to 0.274Mpa but after more than 4 % Kota stone Dust are added then strength will not increased.
Compact hybrid electrohydraulic actuators using smart materials: A review

The development of compact hybrid electrohydraulic actuators driven by various smart materials has been widely reported in the literature in recent years. Such solid-state-induced strain actuators have applications in a variety of aerospace and automotive and mechanical engineering fields. These devices are capable of producing high stroke (or displacement) and high force (or pressures) in a compact form factor by utilizing the large bandwidth and energy density of currently available smart materials. The basic operation of these hybrid actuators involves high-frequency bidirectional operation of an active material that is converted to unidirectional motion of a hydraulic fluid by a set of valves. Over the last decade, several prototype hybrid actuators have been designed using piezoelectric (PZT-5H), magnetostrictive (Terfenol-D), and electrostrictive (PMN-PT) materials as the driving elements, with actuation frequencies ranging from 10 Hz to 1 kHz. Power outputs and volumetric flow rates have reached up to 20 W and 40 cm3/s, respectively. Different mathematical models have been developed to evaluate the performance of these hybrid actuators. While early efforts focused on a simple, quasi-static approach to simulate pump operation, more complex dynamic models have been recently developed to capture the complex interaction between the smart material and the transmission fluid at high operating frequencies. The objective of this survey is to review the state-of-the-art in compact hybrid electrohydraulic actuation systems and to summarize design and modeling efforts.

Effect of Post Deposition Annealing on the Structural and Electrical Properties of NbTiN Thin Films Deposited by Reactive Bias Target Ion Beam Deposition Technique

Nb-based superconducting alloys, such as NbN and NbTiN, can have a superconducting energy gap near twice that of elemental Nb, thus, being ideal candidates for low-loss superconducting circuits operating above the gap frequency of Nb. We are particularly interested in these materials for THz-frequency superconducting-insulating-superconducting (SIS) mixers, kinetic inductance detectors, and traveling wave kinetic inductance parametric amplifier devices. We recently reported the use of an alternative synthesis technique, reactive bias target ion beam deposition (RBTIBD), used to realize high-quality NbTiN films and high-energy gap NbTiN/AlN/NbTiN SIS heterostructures. In this paper, the effect of post-deposition annealing on the electrical and structural properties of room temperature deposited RBTIBD NbTiN was investigated. Our room temperature RBTIBD NbTiN films were annealed using rapid thermal annealing from 200 to 1000 $^\circ$C. The change in structural and electrical properties was characterized by X-ray diffraction, atomic force microscopy, and four-point probe measurements. The annealed films demonstrated an enhancement in transition temperature (T$_c$), increased crystallinity, larger grain size, and significantly reduced intrinsic stress.
