My favorite physical activity is table tennis, which also happens to be the
world's best brain sport. It is highly aerobic and gets both the upper and
lower body moving in every which way — twisting, bending down low, reaching
up high, and shuffling from side to side. Plus, it gives your brain one
heckuva workout.
Also known as "ping-pong," the game is great for hand-eye coordination and

拆了pump检查follower和camshaft的lobe，follower磨损厉害的话，camshaft lobe也会被磨损。链接里第二个case开了58k，没有磨损camshaft lobe。follower base的黑色部分被磨完了，不过还在。应该是整个base都磨完了,pump plunger的tip才会磨到camshaft lobe。
如果camshaft lobe有严重磨损，但是plunger没事，换follower和camshaft。
如果plunger tip也严重磨损，泥马整个pump就要换了。（dealership TSB）
具体操作链接：
vw或者audi turbo，07年之前的同学们都自行检查吧。一个follower10块左右，趁早换，因为早晚都要换的。不在manual里，悠着点，各位。

发帖数: 27294 | 21 其实teenager就是激素分泌很旺盛，
frontal lobe（大脑前叶，主管抑制不符合social norm的诡异行为）也没发育好
所以有一些冲动，包括暴力冲动，性冲动，叛逆冲动，是很正常的。
大家都是那个年纪过来的。我最近读了一些paper，发现，frontal lobe在23岁才完全
发育好。
所以teenager要是不好好保养脑子，比如说经常失眠，过早饮酒吸烟，搞极限运动撞了
大脑等等
很有可能一辈子，就变成个暴躁易怒的性格，而且不懂得调控自己情绪，很容易悲观。
或者时而亢奋，时而悲观，成了bipolar。。。。
娱乐圈，很多人出道太早，远远在23岁以下，年纪轻轻就不好好睡觉，生活不规律，烟
酒药物过度
所以我高度怀疑（没有证据哈），某些娱乐圈的人就是frontal lobe在这种情况下没发

比3-lobe的50%左右是大有提高，接近Turbo的80%多了，这样机械增压的响应速度等优

另外，Ford家在GT上用的是twin-screw（MB一直都用这种），效率比4-lobe更高（但是

S4那个3.0是纯粹机械增压的，用了最新的Eaton TVS 4-lobe增压器
选机械增压没选涡轮增压的原因主要是packaging
因为如果是bi-turbo的话，增压器要安排在引擎两侧，一边一个
那么B8的引擎舱就会比较拥挤
如果向BMW的N63那样交换进、排气，倒是能把增压器放到中间的V型谷内
但那样引擎就要重新设计了，可能Audi觉得不划算
而恰好这时Eaton出了新的4-lobe，绝热效率大为提高
这样选择机械增压就成了一个不错的方案了
现在用Eaton TVS 4-lobe的引擎不少啦，都是好机器

Temporal Lobe Epilepsy and the Arts
As Eve LaPlante discusses in her book, "Seized," the intense emotions,
sensory experience including vibrancy of colors, and particular mental state
provoked by temporal lobe abnormalities may have contributed to the
creation of significant works of art. A number of well-known writers and
artists are known, or in many cases suspected to have had |

1.Quantiferon -TB（血检）：Positive
2.X-RAY：Abnormal（There is a nodule in the left upper lung zone, measuring
5 mm in diameter that may be calcified. Mild linear opacity in the left
retrocardiac region may represent atelectasis or scarring.）
3.CT：There is a subcentimeter calcified right paratracheal lymph node.
Calcification is present within the right hepatic lobe, as well as a
low-density lesion within the right hepatic lobe which is too small to
characterize.THE VISUALIZED NODULE SEEN |

发帖数: 108 | 44 Thanks for the replies. From the report, it shows hospital used 64-slice CT,
not sure it is the same as spiral CT.
Even though doctor told me it is not serious but she still put me on lovenox
for one week and coumadin for 3 months.
At the beginning I thought the blood clot is in vein but report shows it is
in artery. Which is more serious, in vein or in artery? How important is the
right lower lobe pulmonary artery?
One more piece of info from the report:

7月份b超是这样的，大家看看像不像恶性? 甲状腺双侧叶及峡部大小形体正常，被膜光
滑，腺体组织回声欠均匀，稍增粗，甲状腺左叶内见多处大小不等低等回声结节，较大
者位于腺体浅层，大小2.4*1.0cm,边界清晰。右叶中部深面似见0.7*0.4等回声结节，
边界欠清晰,CDFI上述结节周边可采集散在血流信号。左颌下见1.7*0.8淋巴结回声，左
颌下见2.1*0.9淋巴结回声。
8月份在国内另一家做的，想看一下那个大的变大没，没想到不同医院仪器不一样，没
法比较：甲状腺右叶1.79cm,峡部厚0.32cm,左叶厚1.89cm,实质回声增粗欠均，甲状腺
左叶可见中等回声结节，大小约2.36*1.15cm,边界尚清CDFI:期内可见血流信号显示，
左叶可见多个囊状回声及中强回声结节，较大者约1.1*1.0cm,甲状腺弥漫性改变。国内
这两个看着也不一样.

你说的参考和我说的应该是同源的，都是2010年修正的。我觉得对staging来讲，这应
该是现在最权威的文章了。
你所引的文章中这一句“Patients previously considered T4 if additional tumour
nodules were found in the same lobe are now classified as T3. Additional
tumour nodules outside the primary lobe but in the same lung, are now down
staged from M1 to T4 and they may be suitable for a pneumonectomy. ” 我的理
解是如果是一个肿瘤影响了两片肺叶，算T3，如果是两个肿瘤在同侧不同的肺叶里面，
算T4。这里并没有提到具体的肿瘤分类。
你的心情大家都理解，我们也希望是更早期的诊断，这样预后回更好。你也不用太纠结

到1月可能才慢慢消失。但是现在天气冷，如果我一直在家，就没事，但是如果出去吹

原因是因为鼻子流血，然后做b超查出八个颈部淋巴结.
