Basic Law

The Standing Committee of the National People's Congress has the ultimate authority to interpret and amend the Basic Law and to revoke (廢除) any Hong Kong law that it feels violates the Basic Law.

Article 23 allows Hong Kong Special Administrative Region to prohibit subversion (顛覆) against the People's Republic of China government.

血紅蛋白、肌紅蛋白與胎兒血紅素

Hemoglobin is an iron-containing protein in the blood of many animals. This protein is in the red blood cells of vertebrates that transports oxygen to the tissues. Hemoglobin forms an unstable, reversible bond with oxygen; in the oxygenated state it is called oxyhemoglobin and is bright red; in the reduced state it is purplish blue.

Myoglobin is a protein found in the muscle cells of animals. It functions as an oxygen-storage unit, providing oxygen to the working muscles...In contact with venous blood (not blood in capillaries?), oxygen combines more readily with myoglobin than it does with hemoglobin, favoring the transfer of oxygen from blood to muscle cells.

Information modified from britannica.com

The term ‘red meat’ encompasses beef, veal, pork, lamb and mutton. A high concentration of myoglobin in this type of meat, which in contact with oxygen transforms to reddish oxymyoglobin,

makes myoglobin-rich meats appear red.

情為何物

早上七時許
做夢至歇斯底里
印象很深刻

各處鄉村各處例

前幾天，又有客人購物後想換貨。
She said, "It is legal in my home country."
首先，我沒有說她 illegal.
It's only our company ordinance to refuse exchange of product without reason.
當然，我沒有說出口，只是告訴她 barcode 不同，幫不到她。
被告知不能換貨後，她便態度惡劣。
她是什麼地方，不便透露，免得被人說我 racism，
只可以說是中國南方的一個大島國。

昨天，有一位日籍長者想換貨。
雖然她和她的嚮導都很有禮貌，但我都拒絕了她。
買東西前要考慮清楚，是消費者的責任，
而且我覺得要一視同仁。

另一方面，換貨的收銀程序其實都頗為複雜。
做錯程序便更麻煩，以下也分享一下換貨步驟︰
- 確保客人持正單
- 按「單據（種類）３」
- 確保新（想要的）貨品金額比舊貨（不想要的）高或一樣
- 掃瞄不想要的貨品，按「退貨現金」
- 確保折扣和優惠出現在新賬單上
- 掃瞄想要的貨品，按「退貨現金」
- 補錢或出單（價格一樣的話）
- 重印發票，職員簽署及填寫日期
- 單據上註明退貨原因，再交上會計部

你可以責怪我懶惰，但我覺得原則更為重要。

Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer...The frothing (起泡沫) results from the evolution of carbon dioxide gas...fermentation in a narrow sense to describe the changes brought about by yeasts and other microorganisms growing in the absence of air (anaerobically); he also recognized that ethyl alcohol and carbon dioxide are not the only products of fermentation.

Lorazepam (Oral)

This medication is used to treat anxiety. It belongs to a class of drugs known as benzodiazepines which act on the central nervous system to produce a calming effect. This drug works by enhancing the effects of a certain natural chemical in the body (GABA). Side effects include drowsiness, dizziness, loss of coordination, headache, nausea, blurred vision, change in sexual interest/ability, constipation, heartburn, or change in appetite.

GABA is a neurotransmitter that blocks impulses between nerve cells in the brain. Researchers suspect that GABA may boost mood or have a calming, relaxing effect on the nervous system.

Risperidone (Oral)

It is used to treat certain mental/mood disorders (such as schizophrenia, bipolar disorder). This medication can help you to think clearly and take part in everyday life. It belongs to a class of drugs called atypical anti-psychotics. It works by helping to restore the balance of certain natural substances in the brain. The side effects include drowsiness (昏昏欲睡), dizziness (頭暈目眩), lightheadedness, drooling (垂涎), nausea, weight gain, or tiredness. Dizziness and lightheadedness can increase the risk of falling.

It is used to treat schizophrenia, bipolar disorder, or irritability associated with autistic disorder. This medicine is available only with your doctor's prescription.

熱衰竭與中暑

酷熱可以導致熱衰竭或中暑。當環境溫度相等或高於體溫時，人體便不能以輻射方式散熱 (radial heat transfer)。如濕度亦高，汗液的蒸發會受阻。

當身體缺乏水份時，例如運動時未有適當地補充水份，會引致熱衰竭。如患者清醒及沒有嘔吐，應讓他慢慢啜飲大量清水(電解質飲料、牛奶亦可)。

中暑患者在非常酷熱、潮濕、無風的環境下，各種散熱的機能不能正常運作，令體內的恆溫器 (human thermostat) 失常，體溫上升。中暑是有可能致命的。

熱衰竭患者會大量出汗；中暑病人會停止出汗。

五月逃亡潮

逃港（即逃亡至香港），香港又名「偷渡潮」，是指上世紀五十年代至八十年代，約有一百萬內地居民，由深圳越境逃往香港，這被認為是冷戰時期歷時最長、人數最多的逃亡事件，史稱「大逃港」。

這是一橫跨三十年的逃亡史，出現過四次大規模的逃港潮，分別是1957年、1962年、1972年和1979年；現在距離1962年的那次逃港高潮，已過去整整五十年。

Pokfulam Village

Pokfulam, a small village perched (坐落) on a hillside in the west of Hong Kong Island, is characterized by narrow lanes and alleys twisting through the village, around small traditional buildings and newer structures. The modest (簡樸) appearance of Pokfulam belies (掩飾) its importance to the history of Hong Kong. The storied Dairy Farm Group, set up in Pokfulam in 1886 to provide Hong Kong with fresh milk, expanded rapidly, offering employment to many of Pokfulam's residents. The community's most important tradition is the Fire Dragon Dance that takes place during the Mid-Autumn Festival every year. An incense-lit hay dragon visits each household, bringing blessings to the residents and fostering a spirit of community.

Pokfulam Village was included on the 2014 World Monuments Watch to raise awareness of its significance and scarcity in the modern metropolitan Hong Kong.

Natural delivery is better than C-section

Once the waters (amniotic fluid) break, colonization begins...As it emerges from its mother, it gets another dose of microbes alongside those from the vagina...During human labor and birth, the contraction-inducing hormones and the pressure of the descending baby cause most women to defecate...After birth, the mother's gift of a new coat of microbes, both fecal and vaginal, makes for a simple and safe birthday suit for the newborn.

....the strains and species of the mother's vagina that are most similar to those colonizing the newborn's gut...These vaginal microbes are quite a select bunch - far less diverse than those in the mother's gut - but they seem to have a specialist role in the newborn's developing digestive tract...They are part of a group known as the lactic acid bacteria.

The vagina's lactic acid bacteria are milk eaters. They take the sugar found in milk, lactose, and convert it into lactic acid, creating energy for themselves in the process. Babies are also milk eaters, converting lactose into glucose and galactose, which are absorbed by the small intestine into the blood and then converted into energy for the baby. Any lactose that makes it past small intestine undigested is not wasted. It goes straight to the lactic acid bacteria waiting in the large intestine.

...The bacterial communities living in pregnant women's vaginas are different ones from those living in the vaginas of non-pregnant women. Among the normal species of the vagina are species more normally found in the gut...During pregnancy the vaginal microbiota shifts, growing less diverse...When a babies is colonized, its gut microbes are relatively diverse, including some of mum's fecal bacteria as well as the vaginal set. But this initial collection also rapidly slims down to just those bacteria that can help with milk digestion.

The early colony that takes up residence in a baby's gut forms a crucial starting point for the microbiota that will develop over the next few months, possibly setting the trajectory for several years.

...millions of babies are born each year without going anywhere near their mothers' vaginas. In some places, giving birth by Cesarean section is more common than giving birth vaginally.

...Cesarean babies are more susceptible to infections. Up to 80 percent of cases of Methicillin-resistant Staphylococcus aureus (MRSA) infections in newborns occur in those born by Cesarean. As toddlers, children born by C-section are more likely to develop allergies.

...Sampling the gut microbiota of babies can reveal whether they were born by C-section or vaginally for many months after their birth...But whereas the microbiotas of mother's vagina and the child's gut match following a natural birth, C-section babies and their mums cannot be matched up by looking at their microbes.

Even vaginal births are relatively germ-free affairs in the Western world...Beds, hands and tools are all washed with antibacterial soaps and alcohol rubs before they come into contact with the laboring woman or her baby...and there is no doubt that many thousands of mothers and babies are alive because of such hygiene.

Lactose intolerance is the inability of some people to break down the milk lactose using lactase enzyme...There was a difference in the amount of hydrogen in the breath of colicky and non-colicky babies...Excess hydrogen in the breath indicates that bacteria in the gut are breaking down food...If bacteria were producing hydrogen, they must have been receiving a sizable meal.

Oligosaccharides (Oligo- means few) are carbohydrates made up of short chains of simple sugars...They are manufactured in the breast tissue of pregnant and breast-feeding women...Bifidobacteria in microbiota of breast fed babies make enzymes the can use oligosaccharides as their sole food source. As a waste product, the produce the all-important short-chain fatty acids (including lactic acid) that is particularly valuable in babies. These feed the cells of the large intestine, and play a crucial role in the development of a baby's immune system.

Before pathogenic bacterium can do any damage, it must adhere to the intestinal wall using special attachment points on the bacterial surface. Oligosaccharides fit perfectly into these points, depriving nasty species of a foothold.

Checking the blood for migrant microbes shows the route they took. They are stowaways, travelling inside immune cells called dendritic cells. The dendritic cells are willing participants in the trafficking of the bacteria. Sitting among the dense immune tissue that surrounds the gut, these cells are able to reach out with long arms into the intestine to check what microbes are present. Usually, they are responsible for engulfing pathogens, then waiting for another team of immune cells (natural killer cells) to turn up and destroy them. Extraordinarily, the dendritic cells can also pluck unsuspecting beneficial bacteria from among the crowd to engulf and transport through the blood to the breasts.

The microbial content of the colostrum of women who delivered by pre-labor elective Cesarean section is strikingly different from that of women who delivered vaginally...But in women who had in-labor emergency C-sections, the milk microbiota was far more similar to that of mums who delivered vaginally. Something about the labor process sounds a signal, informing the immune system that it is the time to prepare for the baby to be on the outside of the body...many powerful hormones released during labor. Their release alters which microbes are moved form the gut to the breasts in preparation for the emerging baby...

Bottle-fed babies are more prone to infections...Bottle-fed babies are also nearly twice as likely to develop eczema and asthma.

Breast feeding reduces women's risk of type 2 diabetes, high cholesterol, high blood pressure and heart attacks in later life.

關於服從性

上一次雨傘運動，我罵施放催淚彈的前線警員是「警犬」。
因為有親戚是警員的關係，我都心感後悔，覺得自己太過衝動。
今次政府強推逃犯條例，假如謾罵他們是「畜」龍小隊又有何用！
錯在警察？由警校開始，他們被灌輸的是服從，不是良知，也不是獨立思考。
錯在指揮官？他們只能服從於再上一級，要他們與示威者並行，不太可能。
再上一級，不如直指一哥，他只能做門面功夫，說︰「已經很克制。」

逃犯條例一開始是法律問題，之後轉變成政治及外交問題。
香港政府一開始是善意，想為台灣案受害者伸張正義。
推得太急，差不多沒研究沒諮詢，最後連法官都提出抗議。
很明顯，林鄭政權不能走回頭路，因為外交問題是中共決定的。
基本法第十三條列明︰「中央人民政府負責管理與香港特別行政區有關的外交事務。」

今天有人受傷，不管是哪一方，應該不會有人感到好受。
「人皆有惻隱之心」，到今天我仍舊相信。
雖然警方的暴力令人髮指，但我們不應將矛頭全指向他們。
警察從來都是夾在政府和市民之間。

我們沒有能力挑戰中央政權，但香港人理應和平抗爭。
真的不願意看到出人命，到時將後悔莫及。

brown adipose tissue

Brown fat cells possess large numbers of mitochondria...the energy in the mitochondrial electrochemical gradient is released in the form of heat.

Seale, P., & Lazar, M. A. (2009). Brown Fat in Humans: Turning up the Heat on Obesity. Diabetes, 58(7): 1482–1484. Retrieve from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2699856/


Mitochondria are the sites of the Krebs cycle and oxidative phosphorylation.

The basic principle behind oxidative phosphorylation is simple: The energy transferred to ATP is derived from the energy released when hydrogen ions combine with molecular oxygen to form water.

Unlike the enzymes of the Krebs cycle, which are soluble enzymes in the mitochondrial matrix, the proteins that mediate oxidative phosphorylation are embedded in the inner mitochondrial membrane.

earth-cloud capacitor

試想地面與地面上方800米處的雲層是平行極板的電容。 如果雲層的面積為1.0平方公里= 1.0×106平方米，那麼電容是多少？ 如果電場強度大於3.0×106 N / C會導致閃電，那麼雨雲可以承受的最大電荷是多少？

Consider the Earth and a cloud layer 800 meters above the Earth to be the plates of a parallel-plate capacitor. If the cloud layer has an area of 1.0 km² = 1.0×10⁶ m², what is the capacitance? If an electric field strength greater than 3.0×106 N/C causes the air to break down and conduct charge (lightning), what is the maximum charge the cloud can hold?

The definition of capacitance is given by this equation: capacitance C, measured in farads, equals charge Q, measured in coulombs, divided by voltage V, measured in volts.

C = Q/ΔV

V = P / I (unit: J*s^-1A^-1)

(Unit: F = A*s / J*s^-1A^-1 = A²s²J^-1)

Force, F’ = ma

(Unit: kg*m*s^-2)

J = N*1 meter

(Unit: kg*m²*s^-2)

a = (vf - vi) / (tf - ti)

vf: final velocity

vi: initial velocity

tf: final time

ti: initial time

(Unit: F = A²s²J^-1 = A²s²kg^-1m^-2s² = A²s⁴kg^-1m^-2)

Farad (F) is the unit of capacitance. The farad measures how much electric charge is accumulated on the capacitor. 1 farad is the capacitance of a capacitor that has charge of 1 coulomb when applied voltage drop of 1 volt.

Coulomb (C, A*s) is the SI unit of electric charge, equal to the quantity of electricity conveyed (傳送) in one second by a current of one ampere.

Voltage can also be stated as electric potential along a wire when an electric current of one ampere dissipates (消散) one watt (W) of power (W = J/s).

Ampere (A) represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.

Joule (J) is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter.

Newton (N), the absolute unit of force in the International System of Units (SI units). It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one meter per second per second.

The capacitance depends on the area of the plates, A, the size of the gap, d, and the insulator between the plates. We will assume that the insulator is air here:

Ɛ₀ = 1/(4πk)

where k is the Coulomb constant.

(Unit: C²/Nm²)

C = Ɛ₀ A / d

where Ɛ₀ is a constant called the permittivity of free space.

(Unit: C²N^-1m^-2_*m²m^-1 = C²N^-1m^-1)

Electric field strength, E = V/d (Unit: N/C = V/m)

Q = CΔV = CEd

(Unit: C²N^-1m^-1NC^-1m = C)

N/C = kg*m*s^-2*A^-1s^-1 = kg*m*s^-3A^-1

別國的文物

The Rosetta Stone (羅塞塔石碑) is a broken part of a bigger stone slab (a thick plate). It has a message carved (刻) into it, written in three types of writing (called scripts). It was an important clue that helped experts learn to read Egyptian hieroglyphs (象形文字 [ˋhaiərəglif] a writing system that used pictures as signs).

挑釁

客人︰「有沒有 Modern Art 的 Section?」
店員︰「中文書還是英文書？」
顧客︰「英文。」
店員拿起一本英文書。
客人︰「Not Chinese Modern Art. 你們沒有？人地文化館 (文化博物館) on sale.」
顧客不屑一顧轉身離去。
店員向同事訴苦。
同事說︰「你應該告訴她這裡是歷史館，不是文化館，我們主要賣歷史書籍。」
同事還道︰「人地請你食屎，你咪請番人食屎。」
我對同事說︰「我唔識請人食屎。」

沙田文化博物館禮品店將會成為商務印書館旗下。
這位顧客有一股戾氣，身份成疑。

數碼疏散，非也

說謊

客人︰「這一款產品有沒有新的？」
店員︰「所有貨品已經陳列有桌子上。」
這是行規？此是趕客？
因為以上謊言而失去小金額生意，今個星期已經不是一次了。
我們習慣了，就算店面客人不多都習慣說謊。

換一換情況，客人問︰「此書有點殘舊，有沒有新的？」
我們會立刻查一查系統，就算本店沒有複本，也會告訴顧客哪一間分店有存貨。
更甚的是，若果時間許可，我們會替客人致電給分店留書或轉書。
公司是賣書起家，才會產生這種矛盾。
如果在銷售非圖書產品有所改善，客人理應更滿意。
