Authors: de Bruijn Jan Maarten
Published: October 2020

Ensiling pressed beet pulp in 100–500 t pits is common practice and enables stable long-term storage of the pulp when the silage is done according to the standard procedure recommended for this purpose. Storage of much bigger volumes of pressed pulp is more challenging with respect to a stable preservation. Nevertheless, there is practical experience on how to overcome the main issues with long-term storage of pressed pulp in much (10 times) bigger pits, which will be touched on in this paper. In addition, there is growing interest in using plastic tubes, so-called Ag bags or pulp sausages, for ensiling pressed pulp. The main features of this relative new techniques will be mentioned.

A avaliação do estado de conservação de espécies da fauna brasileira, atribuição do Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio), tem representado um esforço imenso e qualificado, agregando centenas de pesquisadores de diferentes instituições. Entretanto, neste processo, ainda é um desafio o envolvimento do conhecimento ecológico local (CEL) de usuários das espécies, o que tende a possibilitar tanto um arcabouço maior de informações para a avaliação quanto a ampliação da articulação social e institucional para a conservação. Essas possibilidades também são almejadas para a gestão participativa de unidades de conservação (UCs), visando maior eficiência e eficácia de suas metas em suas regiões de influência. Neste trabalho, relata-se a aplicação de uma metodologia que pode ser útil nestes dois escopos – no processo de avaliação do estado de conservação de espécies da fauna e na gestão de UCs. A partir da identificação, por pescadores artesanais, de 68 espécies aquáticas (entre teleósteos, elasmobrânquios e crustáceos) que ocorrem na região do Refúgio de Vida Silvestre (REVIS) Ilha dos Lobos/RS, foram selecionadas espécies consideradas importantes para a pesca nos ambientes de estuários/lagoas e oceânico (diferenciando-se os ambientes entre a UC e a costa, e em mar aberto). Sobre essas espécies, foram caracterizadas, de acordo com o CEL, a tendência populacional e as principais ameaças.

It is a most for each actor in Niger’s food production and distribution chain bears responsibility to take the necessary steps to ensure that the products placed on the market do not pose a risk to the health of consumers. Traditional kilishi products in Niger have evolved from natural drying. This study was aimed to determine the relative humidity of the kilishi in contribution to improve its quality. Three varieties of kilishi (ja, fari and rumuzu) samples were analyzed, using an adapted hygrometer at ambient temperature. The results revealed that from the reading of adapted hygrometer 78±1.42% of relative humidity for the kilishi ja; 62±1.83% for kilishi rumuzu and 53±0.67% for kilishi fari. The kilishi ja level of humidity (78%) found was higher than the normal which is 60 to 65%. The relative humidity results indicated that the evaluation on the kilishi varieties was an indicator of degree of dryness leading to improve its quality. It is therefore recommended that strict aseptic measures and proper drying should be observed during the production of kilishi in order to reduce the microbial load to an acceptable level.

Authors: Alam Md Amirul , Ahmad Ismail Noor Elyana
Published: October 2020

The bitter taste of Momordica charantia due to its high level of calcium content limits people from consuming it, although it has enough various beneficial nutrients. Parental line evaluation is prerequisite for any desired improvement activities through breeding.   In this regard M. charantia parental lines were evaluated based on bitterness (high Ca content) and morpho-nutritional attributes to augment additional value and opportunity to be commercialized. Field and laboratory experiments were carried out for three open-pollinated M. charantia varieties to screen low bitterness parental lines based on low calcium contents and other morpho-nutritional qualities, targeting to generalize this important vegetable crops for all types of consumers from child to older age. From the overall results of the study, Variety 2 showed better quality for numbers of fruits per plant, fruit weight (g), moisture content (%), chlorophyll content (mmol/m²), stomatal conductance (mmol/m²s) and nutrients content such as calcium (Ca), nitrogen (N), magnesium (Mg) and iron (Fe). Variety 3 had good quality for morphological parameters like plant height (cm), numbers of leaves per plant, leaf area (cm²), fruit length (cm), phosphorus (P), potassium (K), aluminium (Al) and copper (Cu). Variety 1 had the highest values only for number of branches per plant and amount of sodium (Na) content. After that, Variety 2 was identified for having lowest calcium (Ca) contents compared to the other two varieties. Thus, Variety 2 was selected as better parents to hold good promise for hybridization based breeding programs for varietal improvement in obtaining low bitterness bitter gourd but rich in other nutrient contents.
Current trends in the study of nominalization
Authors: Iordăchioaia Gianina , Soare Elena
Published: October 2020

Nominalization has been at the forefront of linguistic research since the early days of generative grammar (Lees 1960, Vendler 1968, Lakoff 1970). The theoretical debate as to how a theory of grammar should be envisaged in order to capture the morphosyntactic and semantic complexity of nominalization, initiated by Chomsky's (1970) Remarks on nominalization, is just as lively today, after five decades during which both the empirical scope and the methodology of linguistic research have seen enormous progress. We are delighted to be able to mark this occasion through our collection, next to the anniversary volume Nominalization: 50 Years on from Chomsky's Remarks, edited by Artemis Alexiadou and Hagit Borer, soon to appear with Oxford University Press.

Published: October 2020

ABSTRACT

Introduction. Obesity is a condition that increases the challenges in the surgical process. Obesity increases the risk of sleep apnea and affects anaesthetics. This case report aims to discuss the management of anaesthesia in a patient with morbid obesity.

Case. Female, 26 years old, with intramural uterine myoma and morbid obesity, will undergo myomectomy per laparotomy with ASA II physical status, performed anaesthesia with general anaesthesia intubation technique using the anaesthetic agent Propofol 1-2.5 mg/kg titration until the patient falls asleep, fentanyl 1-2 mcg/kg, then the patient was intubated in a ramped position with sleep non-apnea. After it was confirmed that the ETT was entered, 30 mg of a muscle relaxant (atracurium) was added. The operation lasts 1 hour 30 minutes, with a bleeding 250 cc, hemodynamically stable.Conclusion. Morbid obesity has extraordinary implications for anaesthetic management. Various considerations for patients with morbid obesity are needed starting from the preoperative, intraoperative, to postoperative periods. Regional anaesthesia is preferred because the physiological function of unhealthy obese patients is impaired due to excess body weight. Selection of anaesthetic agent and calculation of drug dose is crucial to know because there is a change in the volume of distribution. The pharmacokinetics of most general anaesthetics are affected by the adipose tissue mass, produce a prolonged drug effect, and less predictable.

Published: October 2020

Abstrak---Dalam makalah ini dibahas tentang simulasi performansi multiband cell pada jaringan GSM. Tekniksimulasi yang dilakukan hanya pada sisi performansi multiband cell berdasarkan standart KPI (KeyPerformance Indicator) yaitu TCH trafik, TCH success rate ≥ 95%, SDCCH success rate ≥ 95%, TCH Drop ≤ 2%, SDCCH drop ≤ 0.7 %. Teknologi multiband cell ini merupakan salah satu cara untuk meningkatkanperformansi pada jaringan GSM. Dengan cara menggabungkan BTS GSM 900 dengan DCS 1800 ke dalam satucell yang sama. Penggabungan ini juga dengan cara menghilangkan kanal BCCH (Broadcast Control Channel)di BTS DCS 1800. Dengan menghilangkan kanal ini maka jumlah trafik menjadi meningkat karena kanal BCCHini diganti dengan kanal TCH dan SDCCH. Sehingga DCS 1800 hanya ada kanal untuk trafik dan hanyamenampung trafik. Pada pembahasan ini bahwa teknologi multiband cell dan hasil dari pengukuran KPI dapatdiketahui performansi multiband cell pada jaringan GSM. Performansi multiband cell pada jaringan GSMmenunjukkan bahwa multiband cell memiliki performansi yang baik yaitu TCH success rate menjadi 99.52%,SDCCH success rate menjadi 97.25%, TCH Drop menjadi 1.03 %, SDCCH drop menjadi 0.4%.
