Binary trees are essential structures in Computer Science. The leaf (leaves) of a binary tree is one of the most significant aspects of it. In this study, we prove that the order of a leaf (leaves) of a binary tree is the same in the main tree traversals; preorder, inorder, and postorder. Then, we prove that given the preorder and postorder traversals of a binary tree, the leaf (leaves) of a bi...

consuming a healthy diet throughout the lifecourse helps prevent malnutrition in all its forms as well as a range of non-communicable diseases (ncds) and conditions. but the increased production of processed food, rapid urbanization and changing lifestyles have led to a shift in dietary patterns. people are now consuming more foods high in energy, fats, free sugars or salt/sodium, and many do n...

in recent decades, percutaneous endoscopic gastrostomy ( peg), has changed feeding and care of patients who can not feed orally. this outpatient procedure is done in most of the endoscopy wards and provides care, nutrition and medications for these patients outside the hospital. peg has rare complications and significantly reduces the cost of care and treatment .with invention of this procedure...

Retaining trees in low-input agroecosystems could be key to maintain mycelia of arbuscular mycorrhizal fungi (AMF) and hence, improve soil fertility crop performance. We assessed the impact faidherbia ( Faidherbia albida , Fabaceae) mango Mangifera indica Anacardiaceae) on AMF smallholder farmers’ maize fields. Along distance-from-tree gradients (1, 4, 10, 15 m), we collected assess hyphal dens...

production of high quality with high shelf life of apple fruits, is of great importance. present study investigates the effects of ammonium nitrate and iron on quality and antioxidant properties of apple fruit cultivar gala in a randomized complete block design. foliar application of iron chelate in three levels (0, 5 and 10 mg/l) and soil nutrition of ammonium nitrate in three levels as strip ...

The urease activity index (UI) is a laboratory test to identify underprocessed soybeans. An experiment was conducted to compare the cor­ relation coefficient of laboratory test with some biological experiment to evaluation of extruded full fat soybean (EFFSB). One hundred fortyfour day-old male broiler chicks were divided into 12 groups including 3 treatments with 4 replicates and fed 3 diets c...

It is well-known that, given inorder traversal along with one of the preorder or postorder traversals of a binary tree, the tree can be determined uniquely. Several algorithms have been proposed to reconstruct a binary tree from its inorder and preorder traversals. There is one study to reconstruct a binary tree from its inorder and postorder traversals, and this algorithm takes running time of...

the traditional event tree analysis uses a single probability to represent each top event. however, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. the fuzzy set theory is universally applied to deal with this kind of phenomena. the main purpose of this study is to construct an easy metho...

In December 2019, a new strain of the corona virus, as a subset of coronaviruses was identified for the first time in Wuhan, China. Symptoms included fever, cough, and muscle aches that are very similar to the seasonal flu.
