    Reconstruction of the Part Vegetation on the Headwaters of the Piney Creek Watershed in Houston and Trinity Counties, Texas

    The National Forests and Grasslands of Texas began a project in 1994 for ecosystem management involving multiple disciplines in an holistic approach to resource inventories. We first began with an intensive archival study of the forest acquisition files and the General Land Office (GLO) files in an effort to identify the western limits of the longleaf pine at the time of initial Anglo-American settlement ca. 1850. Vegetation information was gleaned from this work along with an understanding of the historical occupation of the area, aided by plotting this information onto USGS 7.5\u27 maps overlain by the historic Tobin landownership maps. We have since narrowed our focus from the mosaic of a broad area, to the headwaters of the Piney Creek watershed, an area rich in prehistory and history. Archeological survey has provided data for prehistoric occupations dating to the Early Ceramic period (ca. A.D. 500). More recent deed records, and subsequent landline surveys, have data on witness trees in the 1830s, 1860s, and 1890s, and then again after the Forest Service acquired the land in the 1930s, offering an opportunity to study specie composition over a 100 year period. This study on specie composition, tree density, and basal area, provides preliminary indications that fire suppression in the historic period significantly altered the forest composition

    Get PDF
    Andrew Forsberg was a senior at Augustana College, Rock Island, Illinois, in the fall of 1885. His name appears in the college catalog of 1885-1886, along with his birthplace, the year of his birth, and a few other facts. From this start, we researched the genealogy and family history of Andrew Forsberg. This paper contains a short biography of Andrew Forsberg, a report on his ancestors, a report on his descendants, and some open questions for further research

    On Jordan's measurements

    Get PDF
    The Jordan measure, the Jordan curve theorem, as well as the other generic references to Camille Jordan's (1838-1922) achievements highlight that the latter can hardly be reduced to the "great algebraist" whose masterpiece, the Trait\'e des substitutions et des equations alg\'ebriques, unfolded the group-theoretical content of \'Evariste Galois's work. The present paper appeals to the database of the reviews of the Jahrbuch \"uber die Fortschritte der Mathematik (1868-1942) for providing an overview of Jordan's works. On the one hand, we shall especially investigate the collective dimensions in which Jordan himself inscribed his works (1860-1922). On the other hand, we shall address the issue of the collectives in which Jordan's works have circulated (1860-1940). Moreover, the time-period during which Jordan has been publishing his works, i.e., 1860-1922, provides an opportunity to investigate some collective organizations of knowledge that pre-existed the development of object-oriented disciplines such as group theory (Jordan-H\"older theorem), linear algebra (Jordan's canonical form), topology (Jordan's curve), integral theory (Jordan's measure), etc. At the time when Jordan was defending his thesis in 1860, it was common to appeal to transversal organizations of knowledge, such as what the latter designated as the "theory of order." When Jordan died in 1922, it was however more and more common to point to object-oriented disciplines as identifying both a corpus of specialized knowledge and the institutionalized practices of transmissions of a group of professional specialists

    إن الطبيعة الطبوغرافية لسلطنة عمان تجعل نظام الطاقة الشمسية خيارًا قابلاً للتطبيق وموثوقًا لإنتاج الطاقة بكميات كبيرة في سوق الطاقة المتجددة. تشهد العديد من المناطق الصحراوية في عمان مستويات عالية من الإشعاع الشمسي. وهذا مناسب للأنظمة الكهروضوئية لأن كفاءتها تعتمد بشكل أساسي على الإشعاع الشمسي. ومع ذلك، في التطبيقات في الوقت الفعلي، تؤثر العديد من العوامل البيئية على كفاءة الألواح الشمسية وبالتالي على أدائها. في هذه المقالة، تم اقتراح الشبكة الطبيعية (العصبية) الأمامية متعددة الطبقات (MFFN) لتتبع أداء نظام الطاقة الشمسية الكهروضوئية من أجل استبدال أو تحسين أداء نظام الطاقة الشمسية الكهروضوئية بناءً على حالته الحالية. يتم استخدام خوارزمية الانتشار العكسي (BPA) لتدريب MFFN.The topographical nature of the Sultanate of Oman makes the solar power system a viable and reliable option for bulk power production in the renewable energy market. Many desert areas of Oman experience high levels of solar radiation. This is suitable for photovoltaic (PV) systems as their efficiency mainly depends on solar radiation. However, in real-time applications, many environmental factors affect the efficiency of the solar panel and therefore its performance. In this article, the Multilayer Feed Forward Neural Network (MFFN) is proposed to track the solar PV system performance in order to replace or improve the performance of the solar PV system based on its current state. A backpropagation algorithm (BPA) is used to train the MFFN

    Considering that the soil aggregation reflects the interaction of chemical, physical and biological soil factors, the aim of this study was evaluate alterations in aggregation, in an Oxisol under no-tillage (NT) and conventional tillage (CT), since over 20 years, using as reference a native forest soil in natural state. After analysis of the soil profile (cultural profile) in areas under forest management, samples were collected from the layers 0-5, 5-10, 10-20 and 20-40 cm, with six repetitions. These samples were analyzed for the aggregate stability index (ASI), mean weighted diameter (MWD), mean geometric diameter (MGD) in the classes > 8, 8-4, 4-2, 2-1, 1-0.5, 0.5-0.25, and < 0.25 mm, and for physical properties (soil texture, water dispersible clay (WDC), flocculation index (FI) and bulk density (Bd)) and chemical properties (total organic carbon - COT, total nitrogen - N, exchangeable calcium - Ca2+, and pH). The results indicated that more intense soil preparation (M < NT < PC) resulted in a decrease in soil stability, confirmed by all stability indicators analyzed: MWD, MGD, ASI, aggregate class distribution, WDC and FI, indicating the validity of these indicators in aggregation analyses of the studied soil

    Irrigation experiments were conducted during November to April under wheat crop in the winter season of 2012-13 and 2013-14 in the farmer’s field at Galibkhedi village located in Karnal District, Haryana State, India. In the study, collapsible multi-outlet pipe (MOP) along with single outlets pipe (SOP) was tested in farmer’s field under wheat cultivation. Irrigation was carried out in five treatments including tillage (T) with SOP and MOP; zero-tillage (ZT) with SOP and MOP, and furrow irrigation with raised bed (FIRB). Iso-time profile of waterfront spreading and advance indicated that irrigation water distribution was uniform under the plot irrigated using MOP as compared to plot irrigated using SOP. In addition, water distribution was uniform under zero tilled plots as compared to tilled plot. Results implied that MOP has several advantages over SOP in terms of application efficiency (AE) and uniformity of water distribution. Average application efficiency for the first study year was found to be in the order of ZT-MOP (82.41%) &gt; FIRB (76.79%) &gt; ZT-SOP (75.25%) &gt; T-MOP (74.85%) &gt; T-SOP (69.79%). Average application efficiency for the second study year was found to be in the same order as first year with some deviation in values. In the second year values of mean application efficiencies were ZT-MOP (82.58%) &gt; FIRB (77.13%) &gt; ZT-SOP (73.04%) &gt; T-MOP (69.65%) &gt; T-SOP (66.13%). Overall, this study concludes that irrigation under wheat crop using collapsible multi-outlet pipe (MOP) with zero tillage practices is a suitable option for surface irrigation that accomplishes uniform distribution of water with higher application efficiency
