A few easy-to-follow steps to help users troubleshoot potential load cell problems are discussed in this

A few easy-to-follow steps to help users troubleshoot potential load cell problems are discussed in this article. To start with, a good quality digital multimeter – at least a 4 1/2-digit ohm meter – will be required. The tests are: zero balance, bridge resistance, physical inspection, and resistance to ground. This test is effective in determining whether the load cell has undergone a physical distortion, perhaps because of overload, shock load, or metal fatigue. Before beginning the test, the load cell must be in a “no load” condition, meaning that the cell should be taken away from the scale or the deadload should be counterbalanced. Now that the cell is not under any load, the signal leads can be detached, and the voltage across the +signal and -signal can be measured. The color code for determining – and + signal leads is given on the calibration data sheet. The output should be within the manufacturer’s specifications for zero balance, usually + 1% of full scale output. During the test, the excitation leads should remain connected with the excitation voltage supplied by the digital weight indicator. One must be certain to use the exact same indicator that is used in the ce...

Private Pesticide Applicator Certification Class today in Winner

SDSU Extension is hosting a private pesticide applicator certification class today (Jan. 21) from 1:00-4:00 PM (CST) at the Winner Regional Extension Center (325 S. Monroe St. 1 block south of the stop light). Certification is required by law and it gives you the tools to apply pesticides properly, safely, and profitably. You must be competent to read and follow a label, calibrate your sprayer, and apply pesticides. Certification is good for five years and allows you to buy and apply general and restricted use pesticides. A private applicator cannot accept cash for spraying applications but can trade agricultural services; for example, you can spray your neighbor’s field if they bale your hay. All participants are required to bring a government issued picture ID when they attend this certification class. For additional information, please contact the SDSU Regional Extension Center in Winner at 605-842-1267 or Pierre at 605-773-8120. Pierre 214 W.

Macroscopic x-ray powder diffraction imaging reveals Vermeer’s discriminating use of lead white pigments in Girl with a Pearl Earring

Until the 19th century, lead white was the most important white pigment used in oil paintings. Lead white is typically composed of two crystalline lead carbonates: hydrocerussite [2PbCO3·Pb(OH)2] and cerussite (PbCO3). Depending on the ratio between hydrocerussite and cerussite, lead white can be classified into different subtypes, each with different optical properties. Current methods to investigate and differentiate between lead white subtypes involve invasive sampling on a microscopic scale, introducing problems of paint damage and representativeness. In this study, a 17th century painting Girl with a Pearl Earring (by Johannes Vermeer, c. 1665, collection of the Mauritshuis, NL) was analyzed with a recently developed mobile and noninvasive macroscopic x-ray powder diffraction (MA-XRPD) scanner within the project Girl in the Spotlight. Four different subtypes of lead white were identified using XRPD imaging at the macroscopic and microscopic scale, implying that Vermeer was highly discriminatory in his use of lead white. Girl with a Pearl Earring is an iconic oil painting created by the 17th century artist Johannes Vermeer in the collection of the Mauritshuis, The Hague (Fig...

Acute angle-closure glaucoma may be associated with the use of gabapentin prior to glaucoma diagnosis, according

Acute angle-closure glaucoma may be associated with the use of gabapentin prior to glaucoma diagnosis, according to a study conducted by the University of British Columbia. The study identified patients enrolled in the PharMetrics Plus database between Jan. 1, 2006, and Dec. 31, 2016. with acute angle-closure glaucoma (AAG), and 14,377 patients who developed AAG were eligible for inclusion in this study. The use of gabapentin or pregabalin was considered if the patient had received a prescription for either drug in the year before their diagnosis. “To evaluate the impact of the extent of gabapentin exposure in the year before diagnosis, the association between gabapentin use and the incidence of AAG was assessed for each of limited, moderate and significant exposure,” Mitchell J. Browne, MD, and colleagues wrote. Results showed that moderate use of gabapentin in patients in the year before diagnosis was proven to be statistically significantly associated with the incidence of AAG. Current use of gabapentin or any drug examined in this study did not show significance with the incidence of AAG. “To the best of our knowledge, this nested case-control study represents the first coh...

How to Expand Your Greenhouse Facility to Support Cannabis or Hemp Crops: Q&A with Nadia Sabeh

The founder of Dr. Greenhouse discusses important considerations when making the switch from growing traditional greenhouse crops to cannabis or hemp. As cannabis legalization continues to sweep the nation—and the world—those already immersed in traditional greenhouse agriculture may consider converting their facilities to support this new crop. However, growing cannabis or hemp might require more adjustments to existing operations than initially anticipated, and comes with its own unique crop needs, growing conditions and regulations. Dr. Nadia Sabeh, president and founder of Dr. Greenhouse Inc., an agricultural and mechanical engineering firm that specializes in the design of HVAC systems for indoor plant environments, has dedicated her career to helping farmers control their environments to grow crops indoors, in greenhouses and in locations that would otherwise make it impossible or impractical to do so. Here, she shares advice on how to successfully make the switch from growing traditional crops to cannabis or hemp in a greenhouse environment. Nadia Sabeh: I think one of the main considerations is, what were you growing before? [Can] the setup and the design of that greenh...

Optical lace offers soft robots a tactile sensor network

Their article “Optical lace for synthetic afferent neural networks” published in Science Robotics describes various experiments using a 3D-printer to integrate arbitrary 3D grids of soft stretchable light guides throughout the volume of a soft deformable scaffold. Some of the light guides are considered as input cores (receiving light from a LED) while networks of neighbouring light guides act as output cores, only carrying leaked light from the input cores upon deformation. By optically measuring the coupling interactions (all the light power outputs), they were able to sense spatially continuous deformations and localize them with sub-millimetre accuracy, detecting forces as low as 0.3 Newton. In one experiment, they were able to simultaneously locate multiple finger presses and monitor the volumetric structural deformation of a soft scaffold just by measuring the coupling interactions within the optical lace. Here they used 1.5mm diameter polyurethane light guides for the input cores and 1mm diameter light guides for the output cores, loosely held in place into lattice-work channels designed within the scaffold structure and spaced apart by small air gaps in the resting s...

Great Garden Fence Ideas for 2017 - How to Build a Garden Fence PM_Logo PM_Logo

Gear-obsessed editors choose every product we review. We may earn money if you buy from a link. How we test gear. It’s just to keep the deer out, sure, but it’s also a large, permanent, highly visible lawn ornament. Make it how you want it. There are stronger fences out there. Fences more precise in their dimensions, more uniform in their materials. Fences that took less time to build because they were planned out ahead of time, or even bought as an E-Z prefab kit. Mine I kind of made up as I went along. We needed the fence because we have deer. Many deer. Also foxes, bobcats, coyotes, the occasional river rat, chipmunks, squirrels, and something that makes tracks we haven’t been able to identify. I don’t know how many of these animals enjoy eating vegetables, but enough that the fence was mandatory. This is ostensibly a how-to article about fencing in your backyard vegetable garden, but even if you were to follow these steps by the number, your fence would turn out different. As it should. It’s your yard, and your fence, and I learned while building this one that a fence can have personality. My yard, for example, has about a 30-degree slope in the...
