The disruption of hydrological cycle will reduce watershed's ability to store water, so that discharge in dry season decreases and discharge in rainy season increases. These problems are caused by changes in land cover from forested land to non-forested. This study aims to develop a scenario for land cover planning that should be applied in the Lisu Watershed, Barru Regency. This study is mapping based on non-experimental research. The data obtained were analyzed spatially by overlay method. The Soil Water Assessment Tool (SWAT) model is used in preparation of land cover planning scenarios to predict hydrological conditions. The results showed that scenario 2, namely land cover planning based on the district space map pattern is the best scenario. Addition of forest area to 61.60% resulting in the lowest yield of 3461.54 mm/year and 1519.53 mm/year. While the infiltration value produced is the highest infiltration value, which is 2299.20 mm/year.

Published: August 2019

W sezonach wegetacyjnych 2012–2014 przeprowadzono inwentaryzację florystyczną agrocenoz (MOChK), której głównym celem było określenie składu gatunkowego, częstości występowania, zasobności stanowisk oraz możliwości wykorzystania roślin o właściwościach leczniczych. Badania polegały na wykonaniu zdjęć fitosocjologicznych metodą Braun-Blanqueta. W wyniku analizy zgromadzonego materiału stwierdzono występowanie 116 gatunków chwastów – ziół. Pod względem pochodzenia liczbowo przeważały rośliny rodzime – apofity (80 gatunków – 68,9%) nad antropofitami (36 gatunków – 31,1% ogólnej liczby stwierdzonych gatunków). Wśród apofitów dominowały apofity łąkowe (28 gatunków) oraz pochodzące z siedlisk wilgotnych i murawowych (po 19 gatunków). Z obcych gatunków zdecydowanie najliczniej występowały archeofity (30 gatunków). W analizowanej florze zielarskiej większy udział miały gatunki wieloletnie – byliny (61 gatunków) niż gatunki krótkotrwałe (55 gatunków). Dominującą formą życiową były terofity (51 gatunków) i hemikryptofity (41 gatunki). Rośliny zielarskie agrocenoz MOChK najczęściej zaliczane były do gatunków bardzo rzadkich, rzadkich i dość rzadkich (61 gatunków) występujących z niewielkim pokryciem powierzchni. Gatunków bardzo pospolitych i pospolitych było 37. Wśród nich duże pokrycie osiągało 8 gatunków (Chenopodium album, Stellaria media, Gnaphalium uliginosum, Galinsoga parviflora, Anthemis arvensis, Centaurea cyanus, Elymus repens i Viola arvensis). Wśród stwierdzonych chwastów – ziół najbardziej liczną grupę stanowiły gatunki, które do celów farmaceutycznych mogą dostarczać ziele jako surowiec (57 gatunków); były to np.: Epilobium parviflorum, Galeopsis tetrahit, Descurainia sophia, Gnaphalium uliginosum, Hypericum humifusum. W grupie roślin leczniczych stwierdzono 12 gatunków rzadkich i zagrożonych – w regionie i w kraju, m.in. Agrostemma githago, Centaurium pulchellum, Consolida regalis, Hypericum humifusum i Herniaria glabra. Ponadto Helichrysium arenarium i Centaurium pulchellum objęte są ochroną gatunkową.

Soja jest bardzo wartościową rośliną uprawną. Ważnymi składnikami pokarmowymi, niezbędnymi do pełnego wykorzystanie jej możliwości plonotwórczych, są azot i siarka. Celem badań była ocena efektywności rolniczej i ekonomicznej nawożenia azotem oraz siarką stosowanego w uprawie soi. W pracy wykorzystano dane pozyskane z dwuczynnikowego eksperymentu polowego przeprowadzonego w latach 2015–2017, w którym zróżnicowano dawki azotu (I czynnik: 0, 30 i 60 kg·ha–1) i siarki (II czynnik: 0 i 40 kg·ha–1). Do określenia efektywności wykorzystano nadwyżkę bezpośrednią oraz wskaźnik efektywności rolniczej i końcowej nawożenia azotem i siarką. Wykazano, że dawka 30 kg·ha–1 azotu istotnie zwiększyła plon nasion soi, a termin zastosowania tej dawki nie miał znaczenia. Najwyższe plony uzyskano po zastosowaniu 60 kg N·ha–1. Korzystny wpływ siarki stwierdzono w wyniku wyłącznej pogłównej aplikacji siarki w dawce 40 kg ha–1 oraz po łącznym jej zastosowaniu z wprowadzoną pogłównie dawką 30 kg N·ha–1. Wskaźniki efektywności rolniczej i końcowej nawożenia azotem bez dodatku siarki były najwyższe dla dawki 30 kg N ha–1 wniesionej przedsiewnie, a przy łącznym stosowaniu azotu i siarki dla tej samej dawki, ale aplikowanej na początku wypełniania nasion.

Cherries are known as health friendly fruits due to their abundant phytochemical compositions. This study was conducted to determine phytochemical and pomological fruit properties of different cherry species including mahaleb (Prunus mahaleb L.), wild sweet cherry (Prunus avium L.), wild sour cherry (Prunus cerasus L.), two sweet cherries (‘Napoleon’ and ‘Starks Gold’) and one sour cherry (‘Kütahya’) cultivars. For this aim, together with various pomological traits, total phenolics and anthocyanin contents, antioxidant capacity, organic acids, sugars, were analyzed in fruits of relevant genotypes. Results of all examined traits significantly varied between genotypes. Mahaleb showed the highest TSS (30.17%), fructose (8.71 μg/g) and glucose (20.74 μg/g) contents. Wild sour cherry gave the highest antioxidant capacity (13.25 mmol TE/kg total weight), anthocyanin (351.0 mg Pg-3-glk/kg total weight), citric acid (0.56 μg/g) and malic acid (2.96 μg/g) contents. As a rootstock, mahaleb was found to be superior in some of the traits when compared to wild sweet cherry. Significant correlations were observed between various traits. Additionally, principal component analysis (PCA) revealed different relationships among the traits and evaluated genotypes.
The impact of pre-harvest treatment with gamma-aminobutyric acid (GABA) and salicylic acid on vase life and post-harvest traits of tuberose cut flowers
Authors: Babarabie Mehrdad , Zarei Hossein , Eskandari Ali
Published: August 2019

Tuberose (Polianthes tuberosa L.) is an ornamental bulbous plant and a famous cut flower in tropical and subtropical regions. Post-harvest senescence of the cut flowers is the main factor limiting the marketability of most of these species including tuberose. From the perspective of metabolic changes, senescence happens as the result of oxidative processes induced by active oxygen species production. Gamma-aminobutyric acid (GABA) and salicylic acid (SA) are compounds with some functions in the post-harvest physiology of some plants. The present study focused on the effect of GABA and SA on vase life and some post-harvest traits of cut tuberose flowers. The plants were sprayed with GABA (5, 10, or 15 mg L–1) and SA (50, 100, or 150 mg L–1) at three stages during growth and before harvest in a greenhouse (30, 45, and 60 days after the planting of the bulbs) and were observed after harvest until senescence. Results showed that GABA and SA positively affected the vase life, water uptake, fresh weight, ion leakage, total dissolved solids, chlorophyll, protein, and catalase, peroxidase, and ascorbate peroxidase enzymatic activity. They postponed senescence. The highest and lowest vase lives were observed in plants treated with 10 mg L–1 GABA (11 days) and control (distilled water) (7 days), respectively. It was found that the treatment of tuberose with GABA and SA during growth can improve its post-harvest quality. However, it is recommended to conduct further studies on them.

Modern technologies and accurate information on genetic diversity and structure are contributing to improve the plant breeding, in particular for all the minor species with a lack of data. Genetic diversity of 139 different Ficus carica L. genotypes collected from Italy and Croatia, and divided into two subgroups: uniferous (only main crop) and biferous (breba and main crop), was investigated using 49 microsatellite markers. A total of 70 alleles were generated, of which 64 (91.4%) showed a polymorphic pattern indicating high level of genetic diversity within the studied collection. The mean heterozygosity over the 64 single locus microsatellites was 0.33 and the expected and observed averaged variance were 16.50 and 184.08, respectively. The 139 fig genotypes formed two clusters in the PCoA analysis, suggesting a division between Italian and Croatian genotypes. Moreover, the fig accessions could be divided into two main clusters based on the STRUCTURE analysis according to the biological type, uniferous or biferous, with partly overlapping varieties. In conclusion, our results demonstrated that molecular markers were able to discriminate among genotypes and useful for the authentication of fig tree varieties (homonymies and synonymies).

Based on the long-term observations of Crocus heuffelianus Herb., the Red Book species of "Medobory" Nature Reserve, growing on the boundary of the area, the dynamics of the population age structure has been analysed. The study of the population and phenology has been conducted since 1995 at the Botanical Experimental Area (BP-2), which is located in Viknianske forestry (square 32, board 7) and covers an area of 0.1925 hectares.The number and density of the cenopopulation have been studied. The ratio of the number of individuals to the area of the population is taken for the density, and the number of individuals in its entire area – for the absolute number. The number of species ranged from 347 to 753 individuals. The average plant density is 0.27 individuals per square meter. The highest index was in the years 2016 and 2018 – 0.39 and 0.38 individuals per square meter, and the lowest was in 2005 – 0.09 individuals per square meter.During the investigating over the past decade, surveys of plants of different ages (juvenile, virgin and generative), as well as phenological observations were conducted. Allocation of age groups was carried out in accordance with the classification of Melnyk V.I.The population of Crocus heuffelianus Herb in the Reserve is established as a full-fledged and left-handed. Only in 2011 it was intermediate.According to the results of phenological observations, the average long-term date of the vegetation onset is the 15th of March, the beginning of flowering – the 24th of March, the mass flowering – the 1st of April and the end - the 12th of April. The entire flowering cycle is 21 days on average.An important factor that has a significant impact on the state of the population of the species in the Reserve is the spring sowing of bulbs and tufts of plants by sultry European. It is pointed out almost every year, and evidenced by the presence of numerous fresh lanterns and ditches.
Application of titanium-in-quartz geothermometry to magmatic quartz in evolved rocks from the Bushveld Complex, South Africa
Authors: Buthelezi M. , Ashwal L.D. , Horváth P.
Published: August 2019

We report concentration data for the trace element titanium (Ti) in magmatic quartz in eight samples of leucogabbronorite, anorthosite, olivine ferrodiorite and quartz anorthosite from the Main and Upper Zones of the Bushveld Complex. The results, obtained by electron microprobe analysis, were used with Ti-in-quartz geothermometers (TitaniQ) to constrain the solidus temperatures of these rocks. Magmatic quartz is present sporadically in the mafic cumulate rocks of the 2950 m Bellevue borehole (Northern Limb), and commonly occurs as intercumulus, triangular patches, typically between cumulus feldspars and pyroxenes, suggesting that it crystallized late, from trapped interstitial melts. Quartz grains in rutile-bearing samples (implying TiO2 activity = 1) yield Ti concentrations of 48 to 106 ppm that constrain the solidus temperatures of the Bellevue cumulate rocks at T= 677 to 767ºC, using a calibration of the pressure-sensitive geothermometer at 3 kbar, thought to represent the emplacement pressure of the mafic cumulate rocks. These results imply a mean solidus temperature for Bushveld cumulate rocks of approximately 732 ± 31ºC (n = 7). Cathodoluminescence imagery (CL) of quartz from the studied samples reveals a variety of textures that correlate with Ti content, and hence temperature. These include rim-to-core (RC) zoning, homogeneous CL intensity and some samples show irregular patches of variable CL intensity. The observed zoning can be interpreted as intercumulus quartz grains that crystallized from their rims inward towards their cores.
Heat flow in the Bushveld Complex, South Africa: implications for upper mantle structure
Authors: Jones M.Q.W.
Published: August 2019

Geothermal measurements in South Africa since 1939 have resulted in a good coverage of heat flow observations. The Archaean Kaapvaal Craton, in the central part of South Africa, is the best-studied tectonic domain, with nearly 150 heat flow measurements. The greatest density of heat flow sites is in the Witwatersrand Basin goldfields, where geothermal data are essential for determining refrigeration requirements of deep (up to 4 km) gold mines; the average heat flow is 51 ± 6mWm-2. The Bushveld Complex north of the Witwatersrand Basin is an extensive 2.06 Ga ultramafic-felsic intrusive complex that hosts the world’s largest reserves of platinum. The deepest platinum mines reach ~2 km and the need for thermal information for mine refrigeration engineering has led to the generation of a substantial geothermal database. Nearly 1000 thermal conductivity measurements have been made on rocks constituting the Bushveld Complex, and borehole temperature measurements have been made throughout the Complex. The temperature at maximum rock-breaking depth (~2.5 km) is 70°C, approximately 30°C higher than the temperature at equivalent depth in the Witwatersrand Basin; the thermal gradient in the Bushveld Complex is approximately double that in the Witwatersrand Basin. The main reason for this is the low thermal conductivity of rocks overlying platinum mines.

The Bushveld data also resulted in 31 new estimates for the heat flux through the Earth’s crust. The overall average value for the Bushveld, 47 ± 7 mW m-2, is the same, to within statistical error, as the Witwatersrand Basin average. The heat flow for platinum mining areas (45 mW m-2) and the heat flux into the floor of the Witwatersrand Basin (43 mW m-2) are typical of Archaean cratons world-wide. The temperature structure of the Kaapvaal lithosphere calculated from the Witwatersrand geothermal data is essentially the same as that derived from thermobarometric studies of Cretaceous kimberlite xenoliths. Both lines of evidence lead to an estimated heat flux of ~17 mW m-2 for the mantle below the Kaapvaal Craton. The estimated thermal thickness of the Kaapvaal lithosphere (235 km) is similar to that defined on the basis of seismic tomography and magnetotelluric studies. The lithosphere below the Bushveld Complex is not significantly hotter than that below the Witwatersrand Basin. This favours a chemical origin rather than a thermal origin for the upper mantle anomaly below the Bushveld Complex that has been identified by seismic tomography studies and magnetotelluric soundings.
Hydrogeology of the Sterkfontein Cave System, Cradle of Humankind, South Africa
Authors: Hobbs P. , de Meillon N.
Published: August 2019

A water level rise of almost 3 m in the space of two years in the Sterkfontein Cave system since late-2009 necessitated the re-routing of the tourist path through the cave to successively higher elevations on three occasions. It also raised concern for a possible association with copious acidic and sulphate-rich mine water drainage from the West Rand Goldfield (a.k.a. Western Basin) starting in early-2010, and the related threat to the UNESCO-inscribed fossil site. Although these circumstances have had little impact on the tourist value of the site, a prognosis of the impact on cave water level and quality is indicated by virtue of its karst setting and palaeontological significance. Historical and recent potentiometric data, together with ancillary hydrogeological and hydrochemical information acquired in the course of a water resources monitoring programme for the broader Cradle of Humankind World Heritage Site, provides new insight into the hydrogeology of the cave system. An improved understanding of the hydrophysical and hydrochemical response of the cave water system sheds light on the location of this system within the water resources environment. It is proposed that the present-day maximum cave water level is constrained to an elevation of ~1440 m above mean sea level. The recent electrical conductivity of 78 mS/m for cave water is 32% greater than the 59 mS/m recorded in mid-2010 and earlier. Similarly, the recent sulphate concentration of 161 mg/L is 178% greater than the 58 mg/L recorded before 2010. Compared to coeval values for ambient karst groundwater represented by the normative Zwartkrans Spring water, the magnitude of the increases in the springwater are similar, viz. 48% (from 84 to 124 mS/m) in salinity and 166% (from 154 to 409 mg/L) in sulphate. Although a distinct mine water impact is evident in both instances, the values indicate a muted impact on the cave water chemistry compared to the springwater. These and other documented observations better inform the threat from various poorer quality water sources to the fossil site in particular, and to the broader karst water resource in general. This contextualises concern for the hydroenvironmental future of Sterkfontein Cave and other nearby fossil sites such as Swartkrans, Rising Star and Bolt’s Farm. The dynamic response of the water resources environment to a variety of hydrological and hydrogeological drivers reinforces the need for monitoring vigilance across a range of disciplines.

Pengelompokkan jenis kayu jati menggunakan beberapa parameter yaitu tekstur, berat, warna dan lain sebagainya. Pengelompokkan jenis kayu jati biasanya memiliki subjektifitas yaitu ketergantungan dari mata manusia (ahli/pakar). Oleh karena itu diterapkanlah teknologi untuk membantu dalam menganalisis suatu tekstur kayu jati agar bisa diklasifikasikan ke dalam kelompok-kelompok tertentu. Pada penelitian ini jenis kayu jati yang digunakan ada 3 : semarangan, blora dan sulawesi. Proses klasifikasi jati menggunakan pengolahan citra digital dengan Metode Naive Bayes dan k-Nearest Neighbor (k-NN). Analisis yang digunakan adalah tekstur dengan Metode Gray Level Co-occurrence Matrix (GLCM) dan jarak spasial adalah 1 piksel. Berdasarkan hasil pengujian dan analisis, Metode k-NN secara umum baik dalam mengklasifikasikan 3 jenis kayu jati yaitu semarangan, blora dan sulawesi dengan tingkat akurasi di atas 70%. Akan tetapi klasifikasi paling baik untuk jenis kayu jati sulawesi dengan Metode Naive Bayes, tingkat akurasinya sebesar 82,7%.

In Indonesia, the Institute of Food and Drug Administration (LPPOM) MUI is the official institution that provides information about halal products.  However, the lack of information is provided on the website. Halal Nutrition Food is an application that has a function to facilitate the search for halal products that are incorporated in an integrated database in the form of Linked Open Data. To improve the searching features, we exploit BM25F. BM25F can process structured documents such as instances in RDF. The BM25F return the answer based on four fields: product name, manufacturer name, product ID and ingredient name. The weight of each field is calculated using the Analytic Hierarchy Process (AHP) where the product name gets the highest weight value. The number of keywords and the keywords occurrences influence the score of query results.
Features of Distributional Method for Indonesian Word Clustering
Authors: Sujaini Herry
Published: August 2019

We described the results of a study to determine the best features for algorithm EWSB (Extended Word Similarity Based). EWSB is a word clustering algorithm that can be used for all languages with a common feature. We provided four alternative features that can be used for word similarity computation and experimented toward the Indonesian Language to determine the best feature format for the language. We found that the best feature used in the algorithm to Indonesian EWSB is t w w' format (3-gram) with 0 (zero) word relation. Moreover, we found that using 3-gram is better than 4-gram for all the proposed features. Average recall of 3-gram is 83.50%, while the average 4-gram recall is 57.25%.
First Principles Determination of Electronic Excitations Induced by Charged Particles
Authors: Lingerfelt David , Ganesh Panchapakesan , Jakowski Jacek , Sumpter Bobby
Published: August 2019

A time dependent self consistent field based method for determining the rates of electronic excitations induced in materials by the presence of external point charges is presented. The method utilizes the full scalar potential of the external point charge in the interaction Hamiltonian instead of relying on multipolar expansions thereof. A general method is presented for determining the conditions under which dipole selection rules are adequate to describe the electronic response of the material to perturbation by external point charges. The position dependence of point charge induced transition rates between the ground and lowest few excited electronic states was resolved for a small polybenzoid. Notably, electronic excitations that are optically forbidden can be strongly allowed for particular positions of the perturbing point charge. Application of the methods detailed here can lead to an improved understanding of the electronic response of materials under irradiation by beams of charged particles.
Functionalization of Peptide-coated Platinum Nanoparticles for Various Biological Applications
Authors: Shoshan Michal , Li Mao , Vonderach Thomas , Wennemers Helma
Published: August 2019

Functionalizing noble metal nanoparticles is often necessary to tailor their properties, in particular for biological applications such as drug delivery, therapy and imaging. However, this process is highly challenging, due to the complications in maintaining similar geometrical parameters of the nanoparticles as of without functionalization. The heptapeptide H-Lys-[Pro-Gly-Lys]2-NH2 was found to be an efficient additive for the formation and stabilization of small and monodisperse platinum nanoparticles (PtNPs). We show that the same additive peptide can be used as a platform for the functionalization of PtNPs, as demonstrated by the introducion of three different moieties: coumarin for monitoring cellular uptake of the PtNPs; biotin for detecting their stability in human blood serum; and an arginine-containing peptide for enhanced cell penetration. The peptide-coated PtNPs can be functionalized both before and after reduction of the metal ions, in aqueus environment, emphasizing the high robustness of the system.
