Nice. Bt ds title ehnn. Good 4 u sha, cos it made me run here. No source 4 point 3 & 4? |
I use d same l.top (d xact same specs). I started noticing d freezing abt afta a yr. Change ur HDD |
peppy luv: Ok let me change it to Ewu yoruba!!How old are u? |
Itz happening 4 real in Badagary, Lagos! |
Boss Ttdiamonds: The source backin' tis' News is not geniune enough... I've searched the websites of all Nigerian Newspaper sites..and cant find such....Yes o. I tot I was d only one sha |
Impulse80: O my karakunta! It is so dark here that I can't find my mouth to put the garri oooo even when i wan piss i could not see my prick because of the darkness o Evn a blind man knws whr his mouth is. Was d@ supposed to b funny? |
BMZK: I guess it is happening in Calabar!Well, you liest |
Lord Babs: you must be higher on thisSnake venom!? Na die 4 am b d@ o, mehn dah beer no b hia o |
Lionbite: My people no be eclipse o...... Na RAPTURE!!! It has already reached akure where people have reported to have seen men ascending *Dusts Bible* oh boi, so this book still deyD book go everly dey |
Here in Lagos, itz happening btwn 12:50 and 4:01 |
longjohnsilver: I don't like talkin on tribal issues here in nl...buh seriously why oh why must u read meaning to an innocent post...so had it been d other way round u wud av cared less abi...d op only talked about tins happening around him so is it his fault dat ma igbo brothers are d ones in dat situation??...we need to stop dis ish of tribe for every little for dis nation to grow...Look beyond the tribe nxt time biko, it wud help you go a long way...I rest my caseD OP is evn an Igbo guy o |
engrflames: I w' committe suicide!Hahahaha...abeg dn't committee suicide o, try commit suicide, itz way better. U can thank me 78yrs frm now |
#1-stunner:I knew this cld only come frm a lady- I chkd ur profile immediately I read ur comment & I shook my head 4 u. I dint evn notice d names wen I read it, must ppl always think lyk ds?? |
Victoriousvic: Quick question:m guessing u'r either stil in sec or ur uni is one of those wt xtremely slow calender. FYI most unis (myn inclusive) were prepping 4 dia 2nd semester exams b4 d strike. U cld jst hv passed by & nt comment at all! |
abes: Yes, you are right, the students will organize exams for themselves, mark and grade themselves, issue certificates themselves, smh.This got me laffing real hard, d guy think say na beans. Itz true wat they claim dey r fyting 4 is noble,bt I jst feel we shld look past ASUU & their "ways" in helping to renovate d education sector. I mean, dey'v bn going on strike snc '80! |
AbdH: You stopped worshiping your creator and started worshiping the created. You are the one who needs to be found bro.Ohw-k. Duly noted. Thanks a mil ![]() |
kentozybee: luk at dis dementd human being oooo wat concerns me if if is SEE or SAW,I was once a muslim bt nw i av seen d lyt u shuld also get a lyfUsed to b a muslim too, I was lost but found. |
.NET:U got me laffing real hard. As much as we 8 to accept it, MTN tops dem all. Though dey eff u @ tyms, we still cnt take it away frm dem. |
pictures |
ogeoflyf: Only God knows what ikechukwu was sayin too davido. Bcz that laff no b here ![]() |
Fynestboi: i dnt undastand your topic, pls rephrase.simply put: Shld undergraduates look past ASUU & "their ways" in helping renovate the education sector? |
My topic: "Shld undergraduates look past ASUU 4 hlp to renovate the educatn section?" i.e We all knw wat dey say dey r mainly fyting 4, will their action brng home d xpected results? (rem they bn going on strike snc '80) m new to d deb8 thing, Boay & Fynst, u guys seem to b d mods here, u sure will knw hw to brng all'o dat into a single topic. Thanks. Nice 1 btw guys |
The image: Transverse cross-section of a very thin sunflower leaf (Helianthus annuus) to a thick tea leaf (Camellia sasquana). Along with total leaf thickness and leaf area, the leaves differ dramatically in cell size and in the thickness of cell walls according to specific mathematical.equations newly discovered by the UCLA.research team. |
Life scientists from UCLA's College of Letters and Science hv discovered fundamental rules of leaf design that underlie plants' ability to produce leaves that vary enormously in size. In their mathematical design, leaves are the "perfect machines," said Lawren Sack, a professor of ecology & evolutionary biology & senior author of the research. The UCLA team discovered the mathematical relationships using "allometric analysis," which looks at how the proportions of parts of an organism change with differences in total size. This approach has been used by scientists since GALILEO but had never b4 been applied to the interior of leaves. Reporting in the October issue of an American Journal of Botany, the biologists focused on how leaf anatomy varies across leaves of different sizes. They examined plant species from around the world, all grown on the UCLA campus. While it is easy to observe major differences in leaf surface area among species, they said, differences in leaf thickness are less obvious but equally important. Grace John, a UCLA doctoral student in ecology & evolutionary biology & lead author of the research says:"Once you start rubbing leaves between your fingers, you can feel that some leaves are floppy and thin, while others are rigid & thick," "We started with the simplest questions -- but ones that had never been answered clearly -- such as whether leaves that are thicker or larger in area are constructed of different sizes or types of cells." WHAT THEY DID: The researchers embedded pieces of leaf in plastic & cut cross-sections thinner than a single cell to observe each leaf's microscopic layout. This allowed them to test the underlying relationship betwn cell & tissue dimensions & leaf size across species.Leaves are made up of three basic tissues, each containing cells with particular functions: the outer layer, or EPIDERMIS; the MESOPHYLL, which contains cells that conduct photosynthesis; & the VASCULAR TISSUES, whose cells are involved in water & sugar transport. THEN: The team found that the thicker the leaf, the larger the size of the cells in all of its tissues -- except in the vascular tissue. :These relationships also applied to the components of the individual cells. Plant cells, unlike animal cells, are surrounded by carbohydrate-based cell walls, & the scientists discovered that the larger cells of thicker leaves are surrounded by thicker cell walls, in a strict proportionality. The team was surprised by the "extraordinary" strength of the relationships linking cell size, cell-wall thickness and leaf thickness across diverse and distantly related plant species. These relationships can be described by new, simple mathematical equations, effectively allowing scientists to predict the dimension of cells & cell walls based on the thickness of a leaf. In most cases, the relationships the team found were what is known as "isometric." This means that if a leaf has a larger cell in one tissue, it has a larger cell in another tissue, in direct proportion, as if you blew up the leaf & all its cells using Photoshop. By contrast, a leaf's area is unrelated to the sizes of the cells inside. This allows plants to produce leaves with a huge range of surface areas without the need for larger cells, which would be inefficient in function, the researchers said. The team hypothesized that these strong mathematical relationships arise frm leaf devt -- the process by which leaves form on the branch, growing from a few cells that divide into many, with cells then expanding until the leaf is fully mature. because light can penetrate only so many layers of cells, leaves cannot vary much in the number of cells arranged vertically. The expansion of individual cells and their cell walls occurs simultaneously & is reflected in the thickness of the whole leaf. On the other hand, the number of cells arranged horizontally in the leaf continues to increase as leaves expand, regardless of the size of the individual cells. The new ability to predict the internal anatomy of leaves from their thickness can give clues to the function of the leaf, because leaf thickness affects both the overall photosynthetic rate & the lifespan- "A minor difference in thickness tells us more about the layout inside the leaf than a much more dramatic difference in leaf area". The design of the leaf provides insights into how larger structures can be constructed without losing function or stability. The new allometric equations are an important step 2ward understanding the design of leaves on a cellular basis. And because leaves are so diverse, there is much to learn! In future research, the group will study species that are very closely related in an effort to uncover any evolutionary relationships betwn leaf design & function. John says: "What makes the cross-sections especially exciting is the huge variation frm one species to the next, some hv relatively enormous cells in certain tissues, & cell shapes vary frm cylindrical to star-shaped. Each species is beautiful in its distinctiveness. All of this variation needs decoding." Culled frm: #ScienceDaily Fundamental & quantitative discoveries lyk dz prove how exciting science can b, thr r so many properties of leaves scientists can't yet imitate synthetically. Jst like John said; "Leaves are providing us with the blueprints for bigger, better things. We just have to look close enough to read them." Evry part of me wishes findings lyk dz cld b made in Nigeria, all we do is cram! even up to PhD level. Thr aint much hlp cumin though.
