In Roman times there was a massive import of olive-oil from Baetica (actualAndalusia) to feed the army at the Limes in Rhineland and Scotland. ThisMediterranean product was transported in large amphorae of the Dressel 20type that bear different types of epigraphy: graffiti, stamps en tituli picti (paintedinscriptions). The Low Countries forming the Hinterland took part inthis commerce, hence the discovery of large amounts of amphora fragments,still bearing regularly epigraphy. This written heritage is not only ill-knownand neglected in the Benelux, but also threatened because of the bad conditionsin which they are collected and stored. The information provided bythese epigraphical sources is of uppermost importance to the knowledge ofthe ancient economy in the Empire, as well in the south as in the north andrepresents an important witness of romanisation. They shed light on the productionof the amphorae and the olive-oil in Baetica, and on its commercialisationto the northern fringes of the Empire, giving at the same time thenames of all the people involved in these activities.

Rubber has been grown for long in the South and East of Thailand. Since 2005, rubber plantations have largely spread to new regions, in the North and above all in the Northeast. Tapping is one of the most important practices to optimize the yield of rubber plantations and farmers income [. If tapping practices are well documented in the traditional growing areas [2, , we lack information for the new rubber producing regions. And so far, no study has been done at the level of the country. Therefore, a survey was conducted with 219 rubber farmers from 10 provinces in four rubber producing regions to describe farmers tapping practices. The objective was to compare farmers practices in the different regions and try to identify some standardization or differentiation factors. Results show that tapping systems used by the farmers vary with the region but everywhere, even in the South and Centre east, the real tapping practices are not really intensive. Tapping practices seem to be linked to farmers rubber experience, the size of mature plantation, the rainfall and the length of the leaf-fall period. So finally, tapping days are irregularly distributed throughout the year which probably affects latex physiology and so, the potential yield of rubber plantations.

<p class="IABSSS">Study literature of Islamic Astronomy in case prayer times, is less from getting specific attention. Furthermore, the schedule of prayer times is very complex. Such as its still being distributed in form converting one to another area. It should be computed based on each district or city. Appearing new case that is coordinates point data (latitude and longitude) where used as center point computations. This thesis is researched the effect and importance implementation of center coordinate point from district or city in the determining of prayer times schedule. The research used mathemathic analytic descriptive and comparative analysis methods. With purpose to know in detail the comparation result from prayer times computations using center coordinate point and otherwise. The result of research shows the effect prayer times schedule can be applied for one district or city area. Meanwhile, computed prayer times schedule that use another center point coordinate not exactly can be applied in one district or city area. Though coordinate different value more than 0,5° and its position located in the south and east center coordinate point. Center coordinate point must be applied because at the base this coordinate point have been considered geographical aspect. Where in width side for the north, south, east and west have been considered and have the equilibrium distance.</p><p class="IABSSS">[]</p><p class="IABSSS">Kajian studi Astronomi Islam dalam persoalan waktu salat kurang mendapat perhatian khusus. Padahal persoalan jadwal waktu salat sangat komplek, seperti masih beredarnya jadwal waktu salat yang dikonversi dari satu daerah ke daerah lain. Sudah seharusnya jadwal waktu salat disusun berdasarkan kabupaten atau kota masing-masing. Persoalan baru yang muncul adalah data titik koordinat (lintang dan bujur) mana yang akan digunakan sebagai acuan perhitungannya. Dalam tulisan ini meneliti dampak dan perlunya implementasi titik koordinat tengah kabupaten atau kota dalam perhitungan jadwal waktu salat. Penelitian ini menggunakan metode deskriptif analitis matematis dan analisis komparatif, yang bertujuan untuk mengetahui secara detail hasil perbandingan perhitungan jadwal waktu salat dengan menggunakan titik koordinat tengah dan selain titik koordinat tengah. Penelitian ini menemukan bahwa, dampaknya jadwal waktu salat dapat diberlakukan untuk satu wilayah kabupaten atau kota. Sedangkan jadwal waktu salat yang diperhitungkan menggunakan selain titik koordinat tengah belum tentu dapat diberlakukan untuk satu wilayah kabupaten atau kota, apalagi selisih koordinatnya diatas 0,5° dan posisinya berada di sebelah selatan dan timur  dari titik koordinat tengah. Titik koordinat tengah perlu diimplementasikan, karena pada dasarnya titik koordinat ini telah mempertimbangkan aspek geografis. Dimana dalam segi luas untuk bagian utara, selatan dan timur, barat nya telah dipertimbangkan dan jaraknya pun seimbang.</p>

The aim of this article is to identify the main mechanisms leading to the NEET status in Italy, Romania, and Bulgaria. It does so by highlighting the differences amongst them and verifying how place of residence effectively affects the connected propensity to this status after having controlled for many personal characteristics through a series of probit models. Furthermore, multiple correspondence analyses produce profound understanding of the NEET phenomenon and associated determinants. The results highlight the need to plan support actions tailored to specific NEET characteristics. Whilst the degree of urbanization impacts upon the NEET status throughout Romania and Bulgaria, Italy shows a strong divide between the North and the South. However, in all three countries there is a need to improve the education system and stimulate higher levels of education as the main measure of NEET prevention.

Landslide of expansive soil slope is a serious disease and difficult to correct in highway construction. And the mechanism of landslide of expensive soil cutting slope is complex, so the traditional slope analysis method is unable to analyze it to obtain the reasonable explanation. But the numeric analytic method can obtain the stress, strain and plastic zone of side slope analysis the distortion process of earth slope and the latent sliding plane reasonably, adopt the safety factors to evaluate the slope stability, The paper based on ANSYS and adopts the nonlinear and elastoplasticity model of soil, and use the theory of the shear strength reduction method with FEM to analysis the rule of NanYou road expansive soil landslide. Keywords:Expensive soil landslide of cutting slope swelling force FEM

The reinforcement of expansive soil cutting slope has been a difficulty for the construction industry. This study selected Wanyi Expressway as the construction background and used finite difference method for the numerical simulation and design optimization of expansive soil cutting slope reinforced by sash girder anchor bolts. Calculation results show that the cutting slope ratio is closely related to the stability of the expansive soil cutting slope and that the length, set angle, and vertical spacing of the anchor bolts significantly influence the deformation of the cutting slope. The original design plan was optimized according to the calculation results, and a positive effect in plan execution was achieved. This study may serve as a reference for other similar construction designs.

Stone buildings have long history in west Hunan, stone is one of the most important building material that has been widely used in traditional building, village and town constructions especially in rural mountainous minority areas where rock resource is abundant. Stone is natural and compatible with the environment. Buildings built with local natural stone material in west Hunan minority areas are worth studying considering sustainable development and culture protection. Stone slab masonry in the south with grey limestone slabs and rubble masonry in the north with brown rubbles are two different types. Stone dominates the exterior, while the interior and main structures are built of wood like most of the traditional Chinese buildings. Traditional building techniques are passed on in the stone buildings while they also form the unique culture image of west Hunan rural areas.

The surficial failure of most expansive soil cutting slopes, subjected to the repeated wet-dry cycles, often occurs during or after rainfall following a long drought. The reason for this, however, is still unclear. Therefore, the laboratory tests were conducted to gain the saturated drained shear strength of the natural Nanning expansive soil considering the combined effects of swelling with loading and wet-dry cycles. The findings indicate that the envelope of shear strength, which significantly drops close or equal to zero, can be well fitted by the generalized power function. At the same time, the effect of shear strength parameters on the stability of the expansive soil cutting slope was investigated. The reasons for the shear strength attenuation of the natural expansive soil and the surficial failure of the expansive soil cutting slopes were analyzed. It is evident that the effective cohesion being small is a vital factor influencing the occurrence of surficial failure of an expansion soil slope. Moreover, an effective flexible support treatment measure was provided.
