چکیده
Kajian perbandingan ciri anatomi dan mikromorfologi pina stip Angiopteris angustifolia C. Presl A. evecta (G. Forst.) Hoffm. [Marattiaceae] di Semenanjung Malaysia telah dijalankan. Sampel kajian diperoleh dari Bangi, Selangor, Bukit Fraser Tanah Tinggi Cameron, Pahang. Objektif adalah untuk mengenal pasti menyenaraikan yang boleh digunakan pengecaman pembezaan dua spesies Angiopteris. Ciri ditemui membina kekunci bagi kedua-dua dikaji. Anatomi diperhatikan melalui kaedah hirisan dengan mikrotom gelongsor, siatan epidermis penjernihan serta cerapan bawah mikroskop cahaya menggunakan perisian Cell B. pula melibatkan teknik saduran emas, titik pengeringan kritikal imbasan elektron SmartSEM. sepunya kehadiran stel ringkas bentuk arka pada tulang pina, sel musilaj agak padat parenkima korteks, peruratan tengah dikotom, tepi terbuka tidak bercabang trikom berlengan pina. diagnosis ialah palsu angustifolia, luaran permukaan abaksial berbentuk bulatan lebar manakala ¾ bulatan. Hiasan kutikel dinding periklin tenggelam antiklin timbul sebaliknya tenggelam. Kesimpulannya, mempunyai nilai taksonomi

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

To present the application of the XOR Theorem to learning theory we rst give the following two de nitions. Let F be a class of boolean functions and let > 0. A strong learning algorithm for F over the uniform distribution queries the function f : f0; 1gn ! f0; 1g and outputs, with probability at least 1 , a circuit C such that Pr[f(x) 6= C(x)] < 1 nO(1) where Pr is the uniform distribution. The...
