Pengukuran Panjang-Berat Ikan dan Sayuran pada Budikdamber (Budi Daya Ikan dalam Ember) Menggunakan Visi Komputer dan Regresi Linier
Authors: Fitriyah Hurriyatul
Published: October 2020

Budi daya ikan dalam ember atau Budikdamber kini banyak diminati masyarakat Indonesia karena dapat dilakukan pada lahan yang terbatas. Lele dan kangkung adalah ikan dan sayuran yang sering dikembangbiakkan pada budikdamber ini. Meski keduanya tergolong mudah untuk tumbuh, namun pemantauan kondisi masih perlu dilakukan. Diantaranya adalah ukuran ikan dan sayuran yang dapat menunjukkan apakah kondisi keduanya baik atau memerlukan penanganan. Penelitian ini membuat sistem pengukuran berat dan panjang ikan dan sayuran pada budikdamber menggunakan visi komputer untuk mengambil fitur dan regresi linier untuk memprediksi ukuran. Kamera dipilih sebagai sensor agar pengukuran dapat dilakukan secara non-kontak. Fitur yang digunakan adalah luas area dari lele dan kangkung yang diperoleh berdasarkan proses segmentasi pada ruang warna Hue dan Saturation. Prediksi berat dan panjang menggunakan Regresi Linier dengan input luas area dan output berat-panjang melalui proses pelatihan data. Hasil pengujian menggunakan Kfold cross Validation pada gambar uji menunjukkan nilai koefisien determinasi R2 yang tinggi pada panjang & berat lele (0,92 & 0,88), namun rendah pada panjang & berat kangkung (0,43 & 0,07). Meski demikian, Mean Absolute Percentage Error (MAPE) dari prediksi ukuran kangkung masih baik yakni 13,37% untuk berat dan 5,78% untuk panjang. MAPE dari pengukuran panjang lele adalah 1,49% dan berat lele adalah 4,49%. Nilai-nilai tersebut menunjukkan bahwa algoritma yang dibangun sudah memiliki akurasi yang baik, namun masih perlu perbaikan dalam hal prediksi ukuran kangkung.

Statistical Arbitrage: Profits through Pairs Trading
Authors: Gupta Saloni
Published: October 2020

Statistical arbitrage is a popular device among hedge fund managers and assets management professionals. It refers to simultaneous buying and selling two different capital assets to earn super-normal profit. By identifying persistent anomalies that violate the efficient market hypothesis, statistical methods can be used to create a trading strategy to generate profit with high probability. A pair trading is one such trading strategy which is based on statistical arbitrage process. Pairs trading can be simple in concept, but can be one of the most complex types of trading in practice. The starting point of this strategy is that stocks that have historically had the same trading patters will have so in future as well. If there is a deviation from the historical mean this creates a trading opportunity, which can be exploited. Gains are earned when the price relationship is resorted. The basic premise of this strategy is that stock prices follow a mean reverting process. The objective of this paper is to identify arbitrage opportunities and calculating profits earned through these opportunities by using statistical tools.

Many questions need to be answered before one can implement such strategy viz. which pair of stocks should be traded, how much do we buy/sell of each stock, how to catch the signal of an opportunity (i.e opening a position) and when to close the position so that profit could be earned. In this paper we have taken daily closing prices from 1/1/2010 to 1/1/2011 of thirty scrips of BSE-Sensex to form pairs. Pairs are formed on the basis of minimum distances between two stocks. We have decided not to invest anything. That is, purchase the same rupee amount of the long stock as we sell of the short stock so that strategy is self-financing. We open a position when the absolute value of the difference gets larger than two of its historical standardization.  To unwind the position, we wait until the first time it crosses zero. To calculate the profit/loss of this strategy, we have used “R-Software”. It is observed that profit could be earned through pairs trading if it is applied without losing patience. By identifying persistent anomalies that violate the efficient market hypothesis, statistical methods can be used to create a trading strategy to generate profit with high probability.
Entrepreneurial Emergence among the Socially Underprivileged Class in India
Authors: Panda Shiba C. , Khuntia Janmejoy
Published: October 2020

It is widely recognized that entrepreneurship development holds the key to all-round economic development of a nation. Entrepreneurship has now become the catchword in India’s economic development as well. India being a multicultural society with high incidence of inequality is divided sharply in terms of the underprivileged and the privileged sections. For widespread economic development India cannot ignore the development of the social groups who are underprivileged and are at the bottom of the pyramid. Data from All-India Census on MSME reflect that the underprivileged sections i.e., SC, ST and OBCs have shown growth in terms of ownership of enterprises and level of employment.

Impact of Restrictions on Participatory Notes on the Indian Stock Market
Authors: Barick Gaurav , Bhakri Anshuman , Singh Ramneek
Published: October 2020

Securities and Exchange Board of India (SEBI) has recently decided to tighten screws on “Participatory Notes” also known as “P-Notes”. P-Notes, or off-shore derivative instruments (ODIs), are instruments issued by foreign portfolio investors (FPIs) to overseas investors who wish to invest in Indian stock markets without registering themselves with SEBI. This makes P-notes susceptible to use for money laundering and round tripping. SEBI’s current move aims to curb these activities by making P-notes a more regulated instrument and thereby making it less attractive. This paper examines the possible effect of a decrease in foreign investment through P-notes on the Indian stock market and finds that investments through P-Notes do not seem to have a significant impact on the Indian Stock Market.
On two remarkable species of Azeliinae (Diptera: Muscidae), previously unknown from the Balkans, but collected from Bulgaria already in the 20th century
Authors: Zielke Eberhard
Published: October 2020

Achanthiptera rohrelliformis (Robineau-Desvoidy, 1830) and Hydrotaea aenescens (Wiedemann, 1830), two species of the subfamily Azeliinae (Muscidae), are recorded for the first time from Bulgaria, although they have been already collected around 1908 and 1973, respectively. Due to the fact that the specimen of A. rohrelliformis has not been determined earlier and that males and females of H. aenescens have been erroneously assigned to Ophyra leucostoma (Wiedemann, 1817), the findings of the two species, new to the muscid fauna from Bulgaria and the Balkan Peninsula, are only reported now.

Over 15 percent of the species have an IUCN conservation status (NT to CR). The most valuable are the following specimens: critically endangered grey-backed myna (Acridotheres tricolor) and two endangered species - echo parakeet (Psittacula eques) and sooty albatross (Phoebetria fusca). This is the 2nd largest collection of exotic birds in Bulgaria.
Efectos del cambio climático en el recurso hídrico de los países andinos
Authors: Del Jesus M. , Paz J. , Navas S. , Turienzo E. , Diez-Sierra J. , Peña N.
Published: October 2020

Latinoamérica presenta una alta disponibilidad y un elevado volumen de recurso hídrico. Este hecho, combinado con una abrupta topografía, permite generar importantes aprovechamientos hidroeléctricos con estructuras relativamente reducidas, lo que ha hecho proliferar este tipo de explotaciones. De manera reciente, sin embargo, ha comenzado a manifestarse inquietud respecto a los efectos que el cambio climático pueda tener sobre las centrales hidroeléctricas, y cómo esto pueda afectar a la disponibilidad y distribución de energía eléctrica en los distintos países. En el presente trabajo presentamos la metodología y principales resultados obtenidos en el estudio Vulnerabilidad al cambio climático y medidas de adaptación de sistemas hidroeléctricos en países andinos que ha cubierto los sistemas hidroeléctricos de Bolivia, Colombia, Ecuador y Perú. Focalizaremos nuestros esfuerzos en el análisis del recurso hídrico, paso previo al análisis de la evolución del recurso hidroeléctrico, a nivel regional, donde se han generado unas bases de datos homogéneas para toda el área de estudio mediante reconstrucción temporal y espacial, haciendo uso de técnicas de krigeado. También se ha procedido a homogeneizar la información sobre tipos de suelo y usos del suelo. La hidrología se ha resuelto con el modelo hidrológico semidistribuido VIC. Se ha analizado el periodo histórico 1980-2010, y se han generado proyecciones de cambio climático para el corto plazo (2011-2040), el medio plazo (2041-2070) y el largo plazo (2071-2100) para los escenarios RCP4.5 y RCP8.5 utilizados en el 5° informe del IPCC (Panel Intergubernamental para el Cambio Climático). Se ha tenido en cuenta además la posible evolución socioeconómica y su impacto sobre los usos del suelo.
Estimación del volumen de agua virtual exportada en productos agrícolas. California como caso de estudio
Authors: Nguyen D.T. , Nolasco D. , Baquero A. , Rosso D.
Published: October 2020

California es el estado con mayores ingresos por exportación de productos agrícolas en Estados Unidos. En la definición de agua exportada se contabiliza el agua contenida físicamente en los productos agrícolas cultivados y transportados fuera de una frontera geográfica, adicionalmente se incluye la evapotranspiración inducida por el riego del cultivo. Como consecuencia de las condiciones climáticas, el agua evapotranspirada se pierde y no está disponible en el ciclo hidrológico local. En el presente estudio, para la estimación del agua exportada se utilizaron datos de los 50 productos agrícolas más exportados desde California (período 2000-2012). Los resultados muestran que, en promedio, el agua exportada en productos agrícolas corresponde a 2.88×1010 m3 año-1, lo que equivale al 68.3% del agua utilizada en riego del cultivo. La mayor parte del agua exportada (67.7%) está representada en la evapotranspiración inducida por el riego del cultivo. El agua contenida físicamente en los productos agrícolas exportados se calculó en 2.32×108 m3 año-1, esto representa menos del 1% del total anual de agua utilizada en California para riego.

Authors: Simao M. , Ramos H.M.
Published: October 2020

Os sistemas de abastecimento, distribuição e drenagem do setor da água são um dos principais tipos de sistemas hidráulicos artificiais com potencial para a instalação de micro-hídricas. Apesar de existirem algumas aplicações de mini-hidroeletricidade nas condutas de adução, as redes de distribuição de águas urbanas e de rega continuam a ser pouco exploradas. Desta forma, com o objetivo de aproveitar o potencial energético, estudou-se uma turbina hélice tubular com 5 pás inicialmente desenvolvida no âmbito do projeto europeu HYLOW em 2008 e testada em HES-SO Valais. Modelações numéricas foram efetuadas por forma a avaliar o comportamento do fluido no interior da turbina. As simulações apresentaram uma boa aproximação com os ensaios experimentais, com valores de desvio abaixo dos 5%.
Amerikanische Bekleidung. La técnica semperiana en la obra de Albert Kahn
Authors: Pancorbo Luis , Martín-Robles Inés
Published: October 2020

This paper proposes a reinterpretation of Albert Kahn's work through the architectural theories of Semper in order to answer certain questions that have persisted about his work, such as, what is the reason for the heterogeneity of his industrial and non-industrial work and what is the relationship between his radical technical innovations and contemporary tradition. Both questions can be answered by an analysis of Kahn’s work through design tools inherited from Gottfried Semper: Bekleidung, the coating principle, and Stoffwechsel. We establish a parallel study of Kahn's work and the work of other architects in which it is documented the strong influences of these theories. We focus in our analysis on Kahn's industrial architecture, since it is not conceivable that Semper’s influence, so evident in its office, commercial and public buildings, would not have any permeability in his industrial work. To demonstrate this influence, we examine buildings that bridge the gap between the industrial and non-industrial design such as the complex for the U.S Aviation School in Langley Field, Virginia and the Natural Science Building in Ann Arbor, Michigan, among others.

Conclusão: A autopercepção negativa de saúde associou-se à menor renda familiar, à inatividade física e à presença de duas ou mais doenças associadas.
Turbulence-permitting air pollution simulation for the
Stuttgart metropolitan area
Authors: Schwitalla Thomas , Bauer Hans-Stefan , Warrach-Sagi Kirsten , Bönisch Thomas , Wulfmeyer Volker
Published: October 2020

Abstract. Air pollution is one of the major challenges in urban areas. It can have a major impact on human health and society and is currently a subject of several litigations at European courts. Information on the level of air pollution is based on near surface measurements, which are often irregularly distributed along the main traffic roads and provide almost no information about the residential areas and office districts in the cities. To further enhance the process understanding and give scientific support to decision makers, we developed a prototype for an air quality forecasting system (AQFS) within the EU demonstration project Open Forecast. For AQFS, the Weather Research and Forecasting model together with its coupled chemistry component (WRF-Chem) is applied for the Stuttgart metropolitan area in Germany. Three model domains from 1.25 km down to a turbulence permitting resolution of 50 m were used and a single layer urban canopy model was active in all domains. As demonstration case study the 21 January 2019 was selected which was a heavy polluted day with observed PM10 concentrations exceeding 50 µg m−3. Our results show that the model is capable to reasonably simulate the diurnal cycle of surface fluxes and 2-m temperatures as well as evolution of the stable and shallow boundary layer typically occurring in wintertime in Stuttgart. The simulated fields of particulates with a diameter of less than 10 µm (PM10) and Nitrogen dioxide (NO2) allow a clear statement about the most heavily polluted areas apart from the irregularly distributed measurement sites. Together with information about the vertical distribution of PM10 and NO2 from the model, AQFS will serve as a valuable tool for air quality forecast and has the potential of being applied to other cities around the world.
Commercial microwave links as a tool for operational rainfall monitoring in Northern Italy
Authors: Roversi Giacomo , Alberoni Pier Paolo , Fornasiero Anna , Porcù Federico
Published: October 2020

Abstract. There is a growing interest in emerging opportunistic sensors for
precipitation, motivated by the need to improve its quantitative
estimates at the ground. The scope of this work is to present a
preliminary assessment of the accuracy of commercial microwave link (CML) retrieved rainfall
rates in Northern Italy. The CML product, obtained by the open-source
RAINLINK software package, is evaluated on different scales (single
link, 5 km×5 km grid, river basin) against the
precipitation products operationally used at Arpae-SIMC, the regional
weather service of Emilia-Romagna, in Northern Italy. The results of
the 15 min single-link validation with nearby rain gauges
show high variability, which can be caused by the complex physiography and precipitation patterns. Known sources of errors
(e.g. the attenuation caused by the wetting of the antennas or random
fluctuations in the baseline) are particularly hard to mitigate in
these conditions without a specific calibration, which has not been
implemented. However, hourly cumulated spatially interpolated CML
rainfall maps, validated with respect to the established regional
gauge-based reference, show similar performance (R2 of 0.46 and
coefficient of variation, CV, of 0.78) to adjusted radar-based precipitation gridded products and
better performance than satellite-based ones. Performance improves when basin-scale
total precipitation amounts are considered (R2 of 0.83 and CV of
0.48). Avoiding regional-specific calibration therefore does not
preclude the algorithm from working but has some limitations in probability of detection (POD)
and accuracy. A widespread underestimation is evident at both the grid box scale
(mean error of −0.26) and the basin scale (multiplicative bias of 0.7),
while the number of false alarms is generally low and becomes even lower
as link coverage increases. Also taking into account delays in the
availability of the data (latency of 0.33 h for CML against
1 h for the adjusted radar and 24 h for the
quality-controlled rain gauges), CML appears as a valuable data source
in particular from a local operational framework perspective. Finally,
results show complementary strengths for CMLs and radars, encouraging
joint exploitation.
Modelling the Ruin of Forests under Climate Hazards
Authors: Yiou Pascal , Viovy Nicolas
Published: October 2020

Abstract. Estimating the risk of collapse of forests due to extreme climate events is one of the challenges of adaptation to climate change. We adapt a concept from ruin theory, which is widespread in econometrics or the insurance industry, to design a growth/ruin model for trees, under climate hazards that can jeopardize their growth. This model is an elaboration of a classical Cramer-Lundberg ruin model that is used in the insurance industry. The model accounts for the interactions between physiological parameters of trees and the occurrence of climate hazards. The physiological parameters describe interannual growth rates and how trees react to hazards. The hazard parameters describe the probability distributions of occurrence and intensity of climate events. We focus on a drought/heatwave hazard. The goal of the paper is to determine the dependence of ruin and average growth probability distributions as a function of physiological and hazard parameters. From extensive Monte Carlo experiments, we show the existence of a threshold on the frequency of hazards beyond which forest ruin becomes certain in a centennial horizon. We also detect a small effect of strategies to cope with hazards. This paper is a proof-of-concept to quantify collapse (of forests) under climate change.
CHANGE PATTERN EXPLORATION WITH HIERARCHICAL BI-CLUSTERING ON SENTINEL-1 SAR AND NIGHTTIME LIGHT DATA
Authors: Che M. , Gamba P.
Published: October 2020

Abstract. In the last few decades, urbanization activities have promoted the emergence of megacities, megalopolis, urban clusters or large urban aggregations, but only a few studies have analyzed them using remote sensing data in both the spatial and the temporal domains. In this paper, combining SAR and multispectral sensors with different resolutions, a novel approach, improved by means of a hierarchical clustering technique, is proposed. Urban changes are mapped in the form of multiple spatio-temporal patterns, visualized by change vectors exploiting the combination of SAR and nighttime light data.
Towards an efficient storm surge and inundation forecasting system

Published: October 2020

Abstract. The Bay of Bengal is a well-known breeding ground to some of the deadliest cyclones in history. Despite recent advancements, the complex morphology and hydrodynamics of this large delta and the associated modelling computational costs impede the storm surge forecasting in this highly vulnerable region. Here we present a proof of concept of a physically consistent and computationally efficient storm surge forecasting system tractable in real-time with limited resources. With a state-of-the-art wave-coupled hydrodynamic numerical modelling system, we forecast the recent super cyclone Amphan in real-time. From the available observations, we assessed the quality of our modelling framework. We affirmed the evidence of the key ingredients needed for an efficient, real-time surge and inundation forecast along this active and complex coastal region. This article shows the proof of the maturity of our framework for operational implementation, which can particularly improve the quality of localized forecast for effective decision-making.
Theory and verification of a new 3D RANS wake model
Authors: Bradstock Philip , Schlez Wolfgang
Published: October 2020

Abstract. This paper details the background to the WakeBlaster model: a purpose-built, parabolic three-dimensional RANS solver, developed by ProPlanEn. WakeBlaster is a field model, rather than a single turbine model; it therefore eliminates the need for an empirical wake superposition model. It belongs to a class of very fast (a few core seconds, per flow case) mid-fidelity models, which are designed for industrial application in wind farm design, operation, and control. The domain is a three-dimensional structured grid, a node spacing of a tenth of a rotor diameter, by default. WakeBlaster uses eddy viscosity turbulence closure, which is parameterized by the local shear, time-lagged turbulence development, and stability corrections for ambient shear and turbulence decay. The model prescribes a profile at the end of the near wake, and the spatial variation of ambient flow, by using output from an external flow model.

"Absolute Power and Authority"
Authors: Farr James
Published: October 2020

This essay offers a detailed textual study of the Fundamental Constitutions of Carolina in light of its history of extensive revisions. In due course, it considers Locke’s considerable secretarial presence and, more guardedly, his authorial presence in these revisions. The Fundamental Constitutions imagined an aristocratic republic in a colonial setting; and its fundamental ideology was one of proprietary absolutism. Its ever-changing articles on absolute power, slavery, and religion are of greatest interest. Important in themselves, they also invite inquiry into their points of contact with Locke’s political theory.
Analysis of estimators for Stokes problem using a mixed approximation
Authors: Abdeslam El Akkad , Elkhalfi Ahmed
Published: October 2020

In this work, we introduce the steady Stokes equations with a new boundary condition, generalizes the Dirichlet and the Neumann conditions. Then we derive an adequate variational formulation of Stokes equations. It includes algorithms for discretization by mixed finite element methods. We use a block diagonal preconditioners for Stokes problem. We obtain a faster convergence when applying the preconditioned MINRES method. Two types of a posteriori error indicator are introduced and are shown to give global error estimates that are equivalent to the true discretization error. In order to evaluate the performance of the method, the numerical results are compared with some previously published works or with others coming from commercial code like Adina system.

The Portrayal of the First Female Saudi Lawyer: A Multimodal Critical Discourse Analysis of Online Newspaper Articles
Authors: Abaalalaa Hessah S. , Alosaimi Reem A.
Published: October 2020

This study utilized a developed MCDA (Multimodal Critical Discourse Analysis) framework proposed by Machin and Mayr (2012). It intends to uncover how interceded verbal and visual choices cooperate to show a shift in the construction of the female Saudi lawyer’s identity in two articles, Saudi and Iranian. The framework is indebted to Van Dijk's (1998) work in which CDA was viewed as a multidisciplinary field where ideology was the basic theory. The MCDA showed that both articles, i.e., Iranian and Saudi, maintained different ideologies in their representations of the first female Saudi lawyer's achievement and used different linguistic and visual choices to portray this achievement.
Crazy Ex-Girlfriend and the Trajectories of Mental Illness in Musicals
Authors: Knapp Zelda , Knapp Raymond
Published: October 2020

In the four-season musical television series Crazy Ex-Girlfriend, mental illness—as in real life—is insidious, lurking in plain sight, hidden only by our willingness to be distracted by the hilarity of the series’ deftly rendered musical numbers, which continually project dark subjects through a camp lens. While Crazy Ex-Girlfriend borrows from earlier musicals dealing with mental illness (Lady in the Dark, Anyone Can Whistle, Man of La Mancha, next to normal) by giving “crazy” a musical voice, it avoids some of the pitfalls of these models, gesturing toward but then denying easy resolutions and idealization. Rather, the series uses its extended scale to consider a fuller spectrum of “crazy,” relishing the musical number’s capacity to play both sides of the crazy-inspirational divide while allowing the trajectories of mental illness to emerge more fully than in a stage musical.
Kosloski’s Kashub Commodities? Authenticity and Value Creation in Wilno Furniture
Authors: Blank Joshua C.
Published: October 2020

We often attach value to the ephemera and objects we collect, especially if there are personal connections or nostalgic importance attached to the items. Over time, some items in a collection become more valuable and desirable than others. Among Canadian antique collectors, one such object of desire is a late nineteenth-century blanket box. Made by a few craftsmen who came from Prussian-occupied Poland and settled near the small hamlet of Wilno, Ontario, Canada, these boxes were originally valued for their function. But many surviving ones were scooped up in the 1960s and 1970s by pickers. Subsequently, they were featured prominently in books, magazines, and antique auctions, and their value increased dramatically. To unpack the life history of and value associated with the Wilno blanket box, this article utilizes an object biography approach. It seeks out transnational connections to Europe and analyzes the object in the physical, technical, economic, and social realms. It also shows how interactions between objects and people contribute to value creation.

The article discusses the problem of stress resistance of a person in the context of the development of professional activities, for example, students during the examination session. Under the concept of resistance to stress, the biological and psychological characteristics of a living organism considered, allowing it to remain stable under the influence of various factors of the external and internal environment. This concept considered as an integral property of a person necessary for the adaptation of an individual to the influence of environmental factors and professional activity manifested in mental and psychological indicators.  The results of the study showed that stress resistance, as a necessary condition for the successful social and psychological adaptation of a person to mastering professional activities in the aspect of synergetic. Accordingly, it is actually predicting professional health and professional longevity of the personality of men and women in connection with an increase in the retirement age as a global social problem.

Protection of Traditional Knowledge: The Work and the Role of International Organisations and Conferences
Authors: Gazizova Asiia Sharifullovna
Published: October 2020

The concepts of traditional knowledge, indigenous people and indigenous knowledge have gained broad use in international discussions on sustainable improvement. Nevertheless, their use is usually subjected to confusion. There have been numerous attempts to clarify the notions of traditional knowledge, indigenous knowledge and people. Although there are no globally approved definitions, this paper is devoted to analysing the approaches of international organisations to the protection of traditional knowledge. The study discusses the work of the international organisations: WIPO, UNESCO, WHO, WTO and FAO, as well as international conferences: Conference of the Parties of Convention on Biological Diversity and UNCTAD. The examples of traditional knowledge illustrate the paper: use of turmeric for wound healing in India, use the Hoodia plant to suppress hunger during hunting in South Africa and others. It is noted that today, at the international level, there are no instruments that ensure comprehensive protection of traditional knowledge. The author concludes that WIPO and UNESCO currently carry out the main work aimed at providing the protection of traditional knowledge. However, other international organisations and conferences, such as WHO, WTO, FAO, UNCTAD and Conference of the Parties of CBD in their work are also addressed some aspects associated with the preservation of traditional knowledge.

The objective of this experiment was to evaluate the in situ dry matter degradability and in situ crude protein degradability of soybean meal subjected to different treatments (thermal, chemical, tannins or saponins). The treatments were: conventional soybean (CON); soybean expeller (EXP); lignosulfonate-treated soybean meal (LIGS); condensed tannin-treated soybean meal (CTAN); hydrolysable tannin-treated soybean meal (HTAN) and Yucca schidigera extract-treated soybean meal (YUC). Samples of 5 g soybean meal were packed in nylon bags and incubated in the rumen of 2 fistulated cattle for seven incubation times (0, 3, 6, 9, 12, 18 and 24 hours), in sequence were washed, dried and weighed. The ruminal kinetics parameters were calculated, and the experiment was completely randomized, with six treatments, four replicates each, with duplicates. The EXP and LIGS treatments showed lower crude protein disappearance (CPD) within 12 hours, the CON, HTAN and YUC treatments had the highest CPD, and the CTAN presented an intermediate value (41.84%) (P < 0.05). EXP had the lowest fraction “a” (soluble) of crude protein (CP) (10.1%) followed by LIGS and CTAN (average of 14.82%). EXP and LIGS had the highest rumen undegradable fraction of CP (57.35 and 51.62%), respectively. In addition, ruminal disappearance rates of dry matter and CP of the treatments ranged from 2.17 to 1.36% h-1 and from 2.63 to 1.2% h-1, respectively. The most efficient treatments to reduce ruminal protein degradation were EXP, LIGS and CTAN.

The use of silage has been an efficient alternative to feed supply during the shortage of roughage in dry periods, providing quality feed that is widely used in ruminant feeding. Thus, the objective of this study was to evaluate the fermentative characteristics and nutritive value of corn silage with Tamani guinea grass (Panicum maximum BRS cv. Tamani) through chemical composition, in vitro dry matter digestibility and protein fractionation. The experiment was conducted in a completely randomized design with four replications. The treatments consisted of five silages: corn; corn with 10% Tamani guinea grass; corn with 20% Tamani guinea grass; corn with 30% Tamani guinea grass; and corn with 40% Tamani guinea grass, totalling 20 experimental silos. The addition of tamani grass to silages was determined based on fresh matter. For ensiling, corn was harvested with 320 g kg-1 DM (dry matter) and Tamani guinea grass in a 30-day development cycle with 286 g kg-1 DM. After 50 days of silage, the silos were opened to analyse the fermentative characteristics, chemical composition and protein fractionation of the silage. The results showed that the addition of Tamani guinea grass in corn silage increased the pH and buffering capacity and reduced the dry matter and lactic acid concentration but did not compromise the fermentative characteristics of silages. The addition of 40% Tamani guinea grass in corn silage provided increased levels of crude protein, in vitro dry matter digestibility, protein A, B1 and C, and decreased the fractions B3 and C, which makes Tamani guinea grass an alternative to improve the quality of exclusive corn silage, resulting in better quality silage.

Automatic milking systems (AMS) have aroused worldwide interest recently. The first installation was by the company Lely in a project in the Netherlands (its homeland) in 1992. But nowadays, AMS represents a growing reality due to lobby for labor issues, rising costs, difficulty finding well-trained workers, and/ or difficulty keeping people on farms. This work aimed to present a review of the literature on AMS, beginning with a brief history of the evolution of the technology, showing advantages and limitations of its use, and ultimately giving some suggestions. The understanding of the technical functioning and operational running can help farmers and technicians in decision making on the adoption of the new technology. Besides workforce reduction and labor quality promotion, AMS has potential to improve feed conversion to milk, milk quality (with lower SCC), and cow productivity, as well as providing useful data and parameters for better farm management. Potential limitations include high investment costs, changes in milk composition (solids, free fatty acids), and increased risk of ketosis in cows.
Comparison of remote site and basement records as excitation of the Vogel building
Authors: McVerry G. H.
Published: October 2020

Two sets of digitized earthquake records from the 17-storey reinforced concrete Vogel building in Wellington show considerable differences between the accelerations recorded by the basement and remote site instruments fifty metres apart. The records obtained on the massive box foundation are considerably attenuated for most frequencies above 1Hz, with peak horizontal accelerations ranging from 54% to 85% of the remote site values. Better matches of the measured responses are achieved using the basement records rather than the remote site records as the ground acceleration excitation applied to linear models derived using systematic identification techniques.
