Winter irrigation(Sagae)

Winter irrigation is the process of flooding paddy fields that would normally be drained in winter. It is sometimes called Fuyu(winter)-Mizu(water) paddy. The presence of an artificial wetland there for a longer period of time, which plays as a habitat for organisms, has a great impact on them. I am particularly interested in how the effects of winter irrigation on biota change with different surrounding environmental conditions. I am currently working on my Master's thesis and will be conducting research in two areas. The irrigation treatment there has started. I will also start to conduct organisms surveys and record environmental factors in the paddy fields. 冬季潅水とは普通は、冬に排水されるはずの水田に水を張る事だ。冬水田んぼと呼ばれることもある。生物の生息地の役割を果たす人工的な湿地がそこにより長い期間存在するという事は生物に大きな影響を与える。の自分は特に異なる周辺環境によって冬期潅水の生物相への影響がどう変わるかという点に注目している。現在修士論文で二つの地域で調査を行う予定でいる。そこでの潅水処理が開始された。これから水田での生物調査や環境要因の記録も始まる。

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
