: The fabaceae are rooted in rosaceae pods known as "vegetables" by the early botanists. They are the third family of angiosperms which includes 642 genus divided into about 18,000 species. The fabaceae family is known as the most important family of the ecosystem as it is indispensable in medicine, agriculture, industry and livestock. The Adenocarpus genus has about 50 species that are frequently found in tropical regions of Northern Africa, the southern part of West Europe and in the central and southern Italy. They are used in traditional medicine for the treatment of several diseases: such as microbial infections, leprosy, scabies, acne, malaria and other plants species are used in agriculture as insecticidal properties. Mainly Adenocarpus mannii species is well represented in the tropical regions of North Africa. It occurs in Angola, Mozambique, Malawi, Guinea, South Africa, Tanzania, and Burundi. In Cameroon, it is encountered in South West Region and West Region. Previous phytochemical studies led to the isolation of several classes of compounds such as flavonoids, alkaloids and triterpenes. Several studies report the phytochemical studies on genus Adenocarpus and chemotaxonomic markers of species of this genus. Herein, we outline all the botanical, pharmacological and phytochemical aspects of Adenocarpus mannii. A brief introduction about fabaceae and the genus Adenocarpus has also been included.

Bioplastics constitute a great opportunity for agriculture, industry and environment. On the one hand, the basic raw material used to fabricate bioplastics is made from renewable agricultural materials, on the other hand, bioplastics have a wide application as packaging and protections in the food and non-food industry as catering products as protection films and foils and as compostable items in agriculture. Also very important is that after achieving the purpose for which they are produced, bioplastics become waste and their cycle is closed as they can be used as compost for agriculture.

Water supply for the domestics use of Central Java Province has been experiencing problems and challenging. With population of 35 million or 16% of Indonesia, it place the province as the third in national population. It have consequently, water need in the province is as such for use of domestics, irrigation/agriculture, industry, etc. Several counties within the province has experiencing water shortage. Particularly during dry season, defisits is inclining that results water use conflicts. Furthermore, conflicts occur not only in counties with water shortage but also in county with sufficient water supply. Conflict is generally triggered by weak management and allocation. This is a result of unlimited territorial sovereighnity of water resources and uncertainty of water rights. Unlimited territorial sovereighnity of water resource contain exclusive right to utilize tap water within the territorial right, in way that the territory hold the sole right to exploit the resource without compensation to neighbouring territory. Hence, water balance should be investigated better and comprehensively. Kata kunci: keseimbangan air, konflik, sumber daya air, Jawa Tengah.

<p><strong>Abstract</strong></p><p><strong><br /></strong></p><p>One of the forms of worship to draw closer to Allah SWT related to property is donated. <em>waqf istismari</em> also called productive waqf, waqf property that is used for investment purposes, whether in agriculture, industry, trade, and services. This endowment is growing problems in the village Longkeyang, where the youth of Longkeyang attempted endowment for the welfare of citizens. In 2006, approximately 10 people from the youth of the Longkeyang together activists AMM (Angkatan Muda Muhammadiyah) began a new initiative is to create a new institution that was later (in 2010) was named after the <em>Badan Pekerja Pengembangan Ranting Muhammadiyah</em> (BP2RM). (1) The first step movement endowment productive Muhammadiyah Youth in Longkeyang namely (a) the anxiety of citizens and youth of the organization is stagnant and also go hand in hand some scholars who died, so no worries "if shortly Muhammadiyah in Longkeyang will run out" as the scorn of other people. (B) Establish <em>Badan Pekerja Pengembangan Ranting Muhammadiyah</em> (BP2RM) Longkeyang village. (C) Movement Endowments Endowments coins For Productive. The two (2) Management of communal ownership of productive Youth in Longkeyang namely (a) From the collected coins donated land and then bought 1,500 m maximized as initial capital. (B) The existing endowments worked together to reduce the cost of key crops <em>albasia</em> timber, then the cost of treatment using the results of intercropping banana plants. The third (c) In the future, earning endowment will be managed by the sharing system, since from 2006 to 2010 the endowment of productive trees used for the expansion of land. (3) The Role of Waqf Productive Youth Welfare Citizens For The Longkeyang namely (a) The results of this productive endowments, are not significant, but citizens can already feel as waqf land managers and also from the results of the banana crop intercropping. (B) Some of the programs that have resulted from the productive management of waqf endowments suppl shroud support fund for volunteers who want to stay.</p><p>Keywords: <em>Endowments, Awqaf Productive, Youth of Muhammadiyah.</em></p><p><strong><br /></strong></p>

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.

AbstractClosed expressions for the first, second, and (in some cases) the third moment of atomic transition arrays now exist. Recently a method has been developed for getting to very high moments (up to the 12th and beyond) in cases where a “collective” state-vector (i.e. a state-vector containing the entire electric dipole strength) can be created from each eigenstate in the parent configuration. Both of these approaches give exact results. Herein we describe astatistical(or Monte Carlo) approach which requires onlyonerepresentative state-vector |RV&gt; for the entire parent manifold to get estimates of transition moments of high order. The representation is achieved through the random amplitudes associated with each basis vector making up |RV&gt;. This also gives rise to the dispersion characterizing the method, which has been applied to a system (in the M shell) with≈250,000 lines where we have calculated up to the 5th moment. It turns out that the dispersion in the moments decreases with the size of the manifold, making its application to very big systems statistically advantageous. A discussion of the method and these dispersion characteristics will be presented.

A small electron probe has many applications in many fields and in the case of the STEM, the probe size essentially determines the ultimate resolution. However, there are many difficulties in obtaining a very small probe.Spherical aberration is one of them and all existing probe forming systems have non-zero spherical aberration. The ultimate probe radius is given byδ = 0.43Csl/4ƛ3/4where ƛ is the electron wave length and it is apparent that δ decreases only slowly with decreasing Cs. Scherzer pointed out that the third order aberration coefficient always has the same sign regardless of the field distribution, provided only that the fields have cylindrical symmetry, are independent of time and no space charge is present. To overcome this problem, he proposed a corrector consisting of octupoles and quadrupoles.

Turkish dermatologist, H. Beheet described the disease as recurrent triad of iritis, oral aphthous lesions and genital ulceration. Auto immune disease is the recent focus on the unknown etiology which is still being discussed. Among the other immunosupressive drugs, CyA included in it's treatment newly. One of the important side effects of this drug is gingival hyperplasia which has a direct relation with the presence of teeth and periodontal tissue. We are interested in the ultrastructure of immunocompetent target cells that were affected by CyA in BD.Three groups arranged in each having 5 patients with BD. Control group was the first and didn’t have CyA treatment. Patients who had CyA, but didn’t show gingival hyperplasia assembled the second group. The ones displaying gingival hyperplasia following CyA therapy formed the third group. GMC of control group and their granules are shown in FIG. 1,2,3. GMC of the second group presented initiation of supplementary cellular activity and possible maturing functional changes with the signs of increased number of mitochondria and accumulation of numerous dense cored granules next to few normal ones, FIG. 4,5,6.
