اِستُخلصت البروتينات من اليرقات و العذارى و الحشرات الكاملة؛ و ذلك من إناث حشرة دبـور ثمـار اللوز و ذكورها (Eurytomidae – amygdali Eurytoma) ، و أجري الرحلان الكهربائي على هلامة متعدد الأكريلامايد. تبين وجود اختلافات في نوعية البروتينـات الموجـودة عنـد اليرقـات و العـذارى و الحشرات الكاملة. يبدأ تركيز البروتينات عند اليرقات في العمر الأول و يزداد في العمـر الثـاني بـشكل واضح، أما في طور العذراء فيلاحظ استمرار وجود البروتينات في بداية الطور و تغيب معظمها مع تقـدم العذراء في العمر. لوحظ وجود اختلافات بين البروتينات الموجودة عند الإناث عن تلك الموجـودة عنـد الذكور إذْ تبين وجود أحد البروتينات عند الإناث من عمر يوم واحد و يستمر وجوده حتى عمـر 7 أيـام، و هو البروتين الأنثوي الأساسي في تشكيل المح في البويضات.
The proteins of larvae, pupae and adults (females, males) of almond seed wasp Eurytoma amygdali -Eurytomidae, were extracted and electro - pHoresied on polyacrylamide gel. Results showed clear differences in the quality of proteins between larvae, pupae and adults. The accumulation of proteins started in the initial stage of larva and increased clearly in the second stage with a continuation in the first stage of pupa, but mostly absent with the progress of the pupa in a lifetime. It was observed that there were differences between the proteins found in females from those in males by showing the presence of a protein when the females from the age of one day and continued its existence until the age of 7 days and this protein was essential in the formation of the yolk of ovocytes.

Five insecticides were evaluated for controlling of almond seed wasp,
Eurytoma amygdali, the study was carried out at Al Fhaila – Homs. The
insecticides were Concord super, Karate zeon, Zenith, Lentrek and Desis
50.The results indicated that insec
ticides affected significantly the infestation,
Concord super caused the lowest infestation (2.66%) compared with the control
(39%) in (2009). In 2010, Karate zeon caused the lowest infestation (2.66%)
where it was (40%) in the control. The economic analysis indicated that
Concord super was the best because of its lowest cost and highest saving money
in secticide (5832.2) Sp., but Karate zeon was the least money-saving insechcide
(5525.4) Sp.
Almond seed wasp Eurytoma amygdali . End is a serious pest on
almond orchards which causes an economic losses in production.
This study was carried out for the morphological description of the
male stages of this pest (larva, pupa and adult) using
stereomicroscope and Scanning Electron Microscope.
This study aims to identifyzeolite phases within the sedimentary-volcanic deposits in Banyas region because of their scientific and economical interest. A group of samples chosen from different sites in the region were studied using X.R.D instrument
with X-powdersoftware. The studies samples were divided into three groups: Igneous, sedimentary and zeolite deposit groups. zeolite deposit, in turn, were put in two subgroups: a new zeolite and already known zeolite subgroups in other regions in S.A.R. The results of this study are quite new in Banyas region.
In vitro rooting was significantly increased by adding indolebutyric
acid (IBA) to medium and rooting was improved by adding ١,٠ g/L activated
charcoal or ٠,١ g/L polyvinylpyrrolidone (PVP). Indoleacetic acid (IAA) (٠,٠ to
٤,٠ mg/L) was not effect
ive for rooting except when used with ٠,١ g/L PVP. A
٩٥٪ survival was achieved when plants were acclimatized ex vitro. Such
procedures could help significantly in clonally propagating bitter almond and
conserving its germplasm.
Scholarly documents have a great degree of variation, both in terms of content (semantics) and structure (pragmatics). Prior work in scholarly document understanding emphasizes semantics through document summarization and corpus topic modeling but te
nds to omit pragmatics such as document organization and flow. Using a corpus of scholarly documents across 19 disciplines and state-of-the-art language modeling techniques, we learn a fixed set of domain-agnostic descriptors for document sections and retrofit'' the corpus to these descriptors (also referred to as normalization''). Then, we analyze the position and ordering of these descriptors across documents to understand the relationship between discipline and structure. We report within-discipline structural archetypes, variability, and between-discipline comparisons, supporting the hypothesis that scholarly communities, despite their size, diversity, and breadth, share similar avenues for expressing their work. Our findings lay the foundation for future work in assessing research quality, domain style transfer, and further pragmatic analysis.
