High-tunnel greenhouses are seen beyond the Spanish moss that drapes the trees at the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) U.S. Vegetable Laboratory in Charleston, South Carolina, on January 28, 2021.
ARS Research Plant Pathologist-Nematologist William Rutter, Ph.D., works to develop tools to manage and mitigate the damage caused by the Meloidogyne enterolobii (the guava root-knot nematode), and other root-knot nematode species.
Nematodes are small microscopic roundworms in the soil.
Meloidogyne enterolobii is an invasive species in the United States southeastern region and causes significant damage to a wide variety of crops worldwide.
These specific nematodes only appeared in the United States within the last 20 years and they've slowly been spreading across the southeastern states causing damage in sweet potato as well as several other crops.
This research will provide resources to develop germplasm that will help breeders develop new crop varieties that are resistant to the nematode as well as management practices that will help farmers directly manage the nematode and stop its spread in the field.
Root-knot nematodes in general and particularly Meloidogyne enterolobii can infect the majority of cultivated plants in the U.S. They're currently causing a lot of damage in sweet potato in the Carolinas, but they also infect other vegetable crops such as pepper, cucumber, watermelon, as well as soybean and cotton. Root-knot nematodes cause billions of dollars of damage each year for the U.S. and farmers globally.

First, a note: I am not a professional, nor do I pretend to be. The usual frantic pace of the end of the semester has kept me from “playing” with the new toy for any length of time.
Conditions of the test
This particular gym is dark and has mixed lighting. Without an Expodisk, the D200 (and the D50 I used last year) rendered images with a strong yellow and/or green cast.
Settings
I used a variety of settings during this tournament. All pictures were shot using auto ISO and auto white balance. The picture controls were normal, with sharpening set to 7. Noise reduction was set to low. I finally settled on the manual mode, 1/400th of a second with an aperture of f2.8. I used a variety of auto focus modes but most of these were shot in single point mode. The metering mode was centerweight.
I used a Nikor AF-S 80-200 f2.8 for all of these shots.
Post Processing
I used Capture NX to convert the files from RAW to JPEG—after I backed everything up, as Capture NX supposedly doesn’t play well with OS X 10.5. The first images are straight from Capture NX, with no additional processing except for a little resizing in Photoshop (the JPEG files out of NX were over Flickr's 10 mb file size restriction). The second example was post processed in Photoshop CS3 with the Define 2.0 plugin.
Conclusions
The D300 is a complicated beast, far more so than the D200. I’ve used a variety of focusing modes: the 3D tracking is a wonder to behold, in the right conditions. A basketball court full of players with similar uniforms isn’t the best situation. I’ve had good results with focus priority (9 point), but I seem to get the best results with the good, old fashioned single point mode.
The auto WB is a wonder. Exposure is quite good, although I was admittedly pushing it with these images. The end of the gym I usually shoot from has an overhead track that prevents any light from reflecting back onto the players’ faces, resulting in a bad combination of dim light and silhouetted players. The D300 handled the situation quite well.
The noise is quite acceptable for my use. Yes, it’s there and quite evident, particularly at 100%. Given that most of these shots were taken with an ISO of 2000 or above, I don’t think that’s bad.
What’s also present is detail: in one shot, the threads on the player’s uniform are quite visible. I could not have done that with the D200 under these conditions, period.
I printed a 13” by 19” shot from a different game that looked good at normal viewing distances (I did clean it up with Define). That might be stretching it, but it also gives you an idea of how much the high ISO game has changed in the past few months.
I’m not a pixel-peeper, so I’ll let viewers form their own judgments. I’ve only held a 40D in a store, I’ve never used a Canon dSLR and I’m neither inclined nor qualified to render a judgment on the image quality of the respective devices. I’m a neutral party in the Canon/Nikon war. Both companies make fantastic cameras, and I’m sure the 40D is capable of giving fine results in similar conditions.

The long diverse journey exploring the themes around OKSparks! Research & Development touched on everything from circuit board assembly and testing, software development, board game making, drawing, graphic design, Amateur Radio License Exams, Research interviews, planning meetings, workshop trial runs, laser cutting, lab visiting, micros residencies, site visits endless car journey conversations on the relationship between art, science and tiffin tins and community building events. Investment in this kind of practice needs time and space; Ok Sparks allowed all this to happen!
horizon montage
Horizon montage of ✠ drakegoodman ✠ photographs with a well known 'action' pic top right.
Please take into account that the pics were taken from slightly different angles which makes the horizon drop a bit too much on the left side, more so in the bottom montage. Also the details in the centre foreground do not correspondent because the photographer changed position.

Located 135 km from Dakar (Senegal), the zone of Niakhar was created in
1962 as a demographic sentinel site. Since then, French and Senegalese have
continuously interacted through demographic activities, social sciences
initiatives and medical research (epidemiology, clinical trials etc.). In this
part of Sahelian land, Science echoes with empirical service, local job
opportunities and fieldwork encounters. Far from scientific controversies and
the expected Manichean scenari, this portfolio shows how scientific research
is actually a daily and transgenerational matter. A two-year study in medical
anthropology followed by another year photographing inhabitants and
fieldworkers provided the opportunity to discover and capture the intimate
traces of scientific research in people’s memories, bodies, homes and family
stories.

ABERDEEN PROVING GROUND, Md. -- U.S. Army research and development centers are collaborating to design new ammunition packaging that could yield significant cost savings and improve battlefield capability, officials said.
Two organizations within the U.S. Army Research, Development and Engineering Command -- the Armament Research, Development and Engineering Center and Natick Soldier Research, Development and Engineering Center -- are developing a packaging system for 5.56-millimeter ammunition as an alternative to fabric bandoleers.
The new system is being developed for the Project Director Joint Services in support of the Program Manager for Maneuver Ammunition Systems. It could save considerable cost by using lightweight and inexpensive plastic packaging materials with a design that will allow for automated packing at the ammunition manufacturing plant, said Dan Klein, an engineer with ARDEC’s Packaging Division who serves as the program lead.

CU professor Andrew Martin and researcher Jessica Metcalf release some of the 1,200 greenback cutthroat trout into Zimmerman Lake in the Arapaho-Roosevelt National Forest on August 8. Metcalf's genetic's work under Martin revealed that the greenback cutthroat trout, the native South Platte cutthroat, barely survived extirpation in a small stream on the slopes of Pikes Peak. This was the first release of the rediscovered greenback into its native range.
