BSF journal review (Ishikawa)

 

Black Soldier Fly (BSF) is a kind of fly native to south America. Today, it distributes to not only America continent but also Asia, Oceania, Africa and Europe area. This fly is attractive because it consumes food waste and can be used as animal feed. It is said that one adult oviposits egg cluster including 400 to 800 eggs. Some researchers in Japan investigates how much 5 kinds of food waste, vegetable, fruit, carbohydrate such as rice, fish and meat can be consumed by BSF larvae. According to the study, vegetable, fruit and carbohydrate are suitable for food waste reduction by BSF larvae. They described that protein content of food affects the weight of larva consuming it. Actually, the result showed larvae consuming mix food containing 5 kinds of food were heavier than those consuming simple food. It is thought that it is because of low protein content in vegetable and fruit and high protein in fish and meat.

アメリカミズアブは南アメリカ原産のハエの仲間です。今日では、アメリカ大陸だけでなく、アジア、オセアニア、アフリカ、ヨーロッパ地域にも分布しています。この幼虫は様々な食品廃棄物を処理できるとともに、動物の餌として利用できるという魅力があります。1匹の成虫は約400～800の卵が詰まった塊を産むと言われています。日本で行われた研究では、野菜、果物、米などの炭水化物を多く含んだ食品、魚、肉類がミズアブ幼虫によってどれだけ処理できるかを調べています。その研究によると、野菜・果物・炭水化物類が幼虫による処理に適しているようです。研究者は食品が含む蛋白質の割合が成長した幼虫の重量に影響すると述べており、実際に上記の食品を全て混ぜた混合食を与えた幼虫が高い重量を示しました。野菜・果物類では低蛋白質、魚・肉類では高蛋白質であったため、成長した幼虫が混合食を与えた個体と比べて低い重量を示したと考えられています。

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

イメージ
                                               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)

イメージ
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
