Someone visited field (Sagae)


 The snow depth is more than 50 cm or 1m in my research field. Paddy field became snow plain. So that if someone visits the field it will be obvious by footprint. In this picture, someone is curious about my camera on the field. I guess it is a fox. Because a single footprint on the straight line is one of the features of a fox. Fox has a role as a predator in the ecosystem. So they also can be related to my study (Ecosystem of winter-flooded paddy). I have to check all of the organisms from microbe to apex predators. It is really excited me.


調査地では50㎝か1m以上積雪しています。夏場田んぼだった場所は見事な雪原になっています。そのため足跡がはっきりわかるため誰かが調査に入ればその痕跡が残ります。この写真では、何かがフィールドに仕掛けたカメラに近づいている事がわかります。おそらくこれはキツネです。キツネは直線状に1つづつ足跡を残す特徴があります。キツネは一般的には鳥や昆虫などを捕食する捕食者とされています。つまり、鳥に注目した私の調査にも関わってくる可能性が高いです。ミジンコなどの微生物から上位捕食者まで全ての生き物をチェックする必要がありそうです。

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

イメージ
We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
