the effect of xanthan and qodume shirazi seed gum on fresh bread quality and its influence on dough rheology were studied. incorporation of 0.3 to 1% of these two gums was investigated to evaluate its effect on the mixing tolerance index (mti), dough development time (ddt), gelatinization temperature (gt), viscosity, dough stability and quality of wheat flour. addition of xanthan and qodume shi...

BACKGROUND Sponges have long been known to be ecologically important members of the benthic fauna on coral reefs. Recently, it has been shown that sponges are also important contributors to the nitrogen biogeochemistry of coral reefs. The studies that have been done show that most sponges are net sources of dissolved inorganic nitrogen (DIN; NH4 (+) and NO3 (-)) and that nitrification, mediated...

Availability and leaching of dissolved inorganic N (DIN = NH4 + NO3) in soil were measured in a periodically flooded forest of the Central Amazon floodplain (v rzea) during one terrestrial phase. Special emphasis was on the effects of a legume and a nonlegume tree species. NH4-N accounted for more than 85% of DIN even at the end of the terrestrial phase although it decreased throughout the expe...

Elementary proofs are presented for two graph theoretic results, originally proved by H. Shirazi and J. Verstraëte using the combinatorial Nullstellensatz. In an undirected graph G = (V, E) we denote by dG(v) the degree of v ∈ V . If F (v) ⊆ N is a set of forbidden degrees for every v ∈ V , then a subgraph G = (V, E) of G is called F -avoiding if dG′(v) / ∈ F (v) for all v ∈ V . Theorem 1 (Shir...

AIM Parents can play an important role in improving the prognosis of avulsed permanent teeth if they are properly informed about the necessary dental first-aid steps at the time of an accident. The purpose of this study was to assess the knowledge of Shirazi parents in traumatic a simple leaflet on improving their knowledge about this topic. MATERIALS AND METHODS One hundred and fifty parents...

Relatively high deposition of nitrogen (N) in the northeastern United States has caused concern because sites could become N saturated. In the past, mass-balance studies have been used to monitor the N status of sites and to investigate the impact of increased N deposition. Typically, these efforts have focused on dissolved inorganic forms of N (DIN = NH4-N + NO3-N) and have largely ignored dis...
