Rural Livelihood Strategies and Household Food Security of Farmers Surrounding Derba Cement Factory, Oromia Region, Ethiopia
Authors: Tesema Dereje , Berhanu Abeje 
Published: January 2019

Abstract
This study examined the livelihood strategies and food security situation of rural households around Derba Cement Factory by taking a randomly selected sample of 215 heads of farm households from three rural kebeles. A mixed research approach was employed to triangulate concurrently collected data through household survey, key informant interviews and focus group discussions. Informed by the sustainable rural livelihood framework, descriptive statistics were used to describe rural households’ livelihood strategies and challenges they faced while inferential statistics was employed to explain households’ food security situations with different livelihood combinations. While mixed farming was found to be the mainstay of the household economy, small-scale irrigation and extracting forest products were also used as supplementary economic activities. More than a half of the respondents (52.5%) reported at least one non-farm activity. Land shortage was identified as a major constraint to expand crop production and this was further aggravated by the activities (e.g. querying leading to displacement) of the Derba Cement Factory. This further affected household labor allocation and natural resources utilization. The result of household food (in) security access scale indicated that 59% of the respondents have experienced food access insecurity in 2016. However, respondents who combined agriculture and non-farm activities appeared relatively more food secure than those engaged in agriculture alone or in non-farm activity only. Overall, households with multiple livelihood strategies had diverse food entitlements to maintain sustainable food consumption. Yet, necessity induced diversification was found to affect food access security of households. This calls for inclusive policies and strategies that integrate rural non-farm activities to subsistence farming in order to assure sustainable livelihood in rural communities.

Abstract
Histamine has an important role in the process of the gastric mucosa inflammation acting via histamine receptor H2 (encoded by the gene HRH2). Single nucleotide polymorphism of the enhancer element of HRH2 gene promoter rs2067474 (1018G>A)may be associated with changes of expression of the receptor. We attempted to clarify the association of this polymorphism with gastric cancer and/or atrophic gastritis in the Latvian (Caucasian) population. The study group consisted of 121 gastric cancer patients and 650 patients with no evidence of gastric neoplasia on upper gastrointestinal endoscopy. Genotyping for rs2067474 was performed with the TaqMan probe-based system using a commercially available probe for RT-PCR. The frequency of the A allele in the gastric cancer group was 0.41% and in the control group — 1.54% (p = 0.231). No significant differences were found comparing genotypes between gastric cancer versus control patients (OR = 0.236, CI95% = 0.030–1.896), patients with (n = 165) versus without (n = 485) gastric metaplastic lesions (OR = 0.854, CI95% = 0.288–2.540) and patients with (n = 297) and without (n = 353) gastric atrophic lesions (OR = 1.145, CI95% = 0.451–2.906). Our findings suggest that the HRH2 -1018G>A polymorphism (rs2067474) is neither associated with gastric cancer nor the grade of atrophic gastritis in the Latvian (Caucasian) population.

Authors: Hyun Seung Hyun , Jin Hyeonseong 
Published: January 2019

Abstract
The purpose of this study was to determine how knee compression affected kinetic variables during vertical jumps. Ten healthy males, age 20s, performed a single maximum vertical jump and a ten-consecutive vertical jump trial without knee compression (control condition) and with knee compression. The collected data of ground reaction force were used to analyse the vertical jump height (VJH), peak active force (PAF), decay rate (DR), peak passive force (PPF), loading rate (LR), and the coefficient of variation (CV). During a maximum vertical jump, knee compression increased the magnitudes of DR, PAF, and VJH by 19.8%, 3.41%, and 4.87%, respectively, compared to those under a control condition. During ten consecutive vertical jumps, PAF and VJH showed statistically significant difference according to the repetition count. Also, the mean and CV of PAF, DR, LR, and VJH over consecutive jumps were higher in magnitude under knee compression condition than under the control condition.

Authors: Jiří Tůma , Pavel Šuránek , Stanislav Žiaran 
Published: January 2019

Abstract
The problem of active vibration control of weakly damped mechanical structures is potentially unstable modes of vibrations due to the positive feedback for some vibration modes. The paper will discuss the change of positive feedback on the negative one using all-pass discrete-time filters. These filters can be arranged in a cascade to stabilize many potentially unstable modes. The piezoelectric actuator as a source of force is used to damp vibration.

Published: January 2019

This research work study the influence of cyclic wetting and drying on free swell potential of untreated and lime treated expansive clayey soils. Such a study is required to understand the behavior of these soils during wet-dry cycles. Two expansive soils (a polwhite bentonite and a kaolinite) with different plasticity indexes were used in this study. The soil samples were treated with different lime content in the order of (3, 5 and 7% by the dry weight of soil). The lime treated soil samples were cured at 20ºC for 28 and 180 days. The untreated and lime treated soil samples were subjected to four wet-dry cycles. Free swell potential and cracks propagation were studied during lime addition and wet-dry cycles. Results showed that, the free swell potential of untreated soil samples; in general; decreased with increasing wet-dry cycles, and all of the soil samples reached equilibrium after the second cycle. While the cracks propagation increased with these cycles, especially of bentonite soil samples. Larger cracks propagation has been observed in the bentonite soil samples. Lime addition enhanced the free swell potential values of the two expansive soils and there was a drastic decrease in free swelling potential and cracks propagation of these soils. The beneficial effect of lime treatment to control the swelling values was partly lost by the first wet–dry cycles, and the free swell potential increased at the subsequent cycles.

Experimental study of water droplet break up in water in oil dispersions using an apparatus that produces localized pressure drops
Authors: Silva Fabricio S. , Medronho Ricardo A. , Barca Luiz Fernando 
Published: January 2019

Oil production facilities have choke/control valves to control production and protect downstream equipment against over pressurization. This process is responsible for droplets break up and the formation of emulsions which are difficult to treat. An experimental study of water in oil dispersion droplets break up in localized pressure drop is presented. To accomplish that, an apparatus simulating a gate valve was constructed. Droplet Size Distribution (DSD) was measured by laser light scattering. Oil physical properties were controlled and three different break up models were compared with the experimental results. All experimental maximum diameters (dmax) were above Kolmogorov length scale. The results show that dmax decreases with increase of energy dissipation rate (ε) according to the relation dmax ∝ ε−0.42. The Hinze (1955, AIChE J.1, 3, 289–295) model failed to predict the experimental results, although, it was able to adjust reasonably well those points when the original proportional constant was changed. It was observed that increasing the dispersed phase concentration increases dmax due to turbulence suppression and/or coalescence phenomenon. Turbulent viscous break up model gave fairly good prediction.

Lakase merupakan salah satu enzim ligninolitik yang memiliki kemampuan mendegradasi lignin. Lakase telah diproduksi menggunakan jamur pelapuk putih Marasmius sp. dalam Fermentasi Kultur Padat (FKP) menggunakan jerami padi sebagai media pertumbuhan. Pengaruh sumber karbon yaitu glukosa, gliserol, dan molase dalam medium produksi lakase digunakan dalam penelitian ini. Konsentrasi 0,5%; 1,0%; dan 2,0% digunakan untuk tiap jenis sumber karbon. Hasil menunjukkan bahwa aktivitas tertinggi lakase diperoleh pada kultivasi hari ke 6-10 dengan masing-masing aktivitas (872,0 U/L (hari ke-6), 1516,67 U/L (hari ke-9) dan 1270,69 U/L (hari ke-10). Aktivitas lakase tertinggi diperoleh pada penggunaan medium gliserol dan molase masing-masing adalah 1422,36 U/L (pada konsentrasi 1%, hari ke-7) dan 113,19 U/L (pada konsentrasi 2%, hari ke-8). Aktivitas tertinggi tersebut sebanding dengan penggunaan medium glukosa. Oleh karena itu, gliserol dan molase dapat digunakan sebagai alternatif sumber karbon untuk produksi lakase dengan fermentasi kultur padat.Kata kunci: glukosa, gliserol, lakase, molase, Marasmius sp., fermentasi kultur padat Influence of Carbon Sources on Laccase Production by White Rot Fungus Marasmius sp. in Solid State FermentationAbstractLaccase is an one of the ligninolytic enzymes that capable to degrade lignin in biomass. Laccase has been produced by white rot fungus Marasmius sp. in Solid State Fermentation (SSF) using rice straw as the solid support media. The influence of carbon sources, i.e. glucose, glycerol and molasses in medium of laccase production were studied in this paper. The concentration of 0.5%, 1.0% and 2.0% were used for each carbon sources. The results showed that the highest lacase activity was obtained within 6-10 days of cultivation. Glucose concentration of 0.5%, 1.0% and 2.0% gave the highest laccase activity were 872.0 U/L (day 6), 1516.67 U/L (day 9) and 1270.69 U/L (day 10) respectively. The highest laccase activity on using glycerol and molasses was 1422.36 U/L (at concentration of 1 % on day 7th) and 1113.19 U/L (at concentration of 2% on day 8th), respectively. This activity was comparable to that of glucose substrate. Therefore, glycerol and molasses gave a potential chance as carbon sources for the strategy on low cost laccase production in solid state fermentation.Keywords: glucose, glycerol, laccase, molasses, Marasmius sp., solid state fermentation.
Kandungan Hexenuronic Acid pada Pulp serta Pengaruhnya terhadap Kualitas Pulp dan Air Limbah: Tinjauan
Authors: Rizaluddin Andri Taufick , Septiningrum Krisna 
Published: January 2019

Proses pemasakan kayu dengan cara alkali aktif akan menghasilkan hexenuronic acid (HexA) yang berasal dari grup glucuronoxylan, tepatnya 4-O-methylglucuronoxylan pada hemiselulosa. Proses hidrolisis HexA menghasilkan dua jenis senyawa furan, yaitu 2-furancarboxylic acid (FA) dan 5-formyl-2-furancarboxylic acid (FFA). Proses hidrolisis HexA hasil proses pemasakan dan terkandung dalam pulp dan kertas merupakan salah satu penyebab proses penguningan pada kertas akibat adanya paparan kelembapan dan panas dari lingkungan. Selain itu, kandungan HexA pada pulp juga dapat meningkatkan konsumsi bahan kimia pada proses produksi pulp dan kertas, terutama pada proses pemutihan dan pengujian parameter bilangan Kappa, serta dapat berkontribusi pada kandungan senyawa organik klorin terlarut dalam air limbah industri pulp dan kertas. Metode untuk menurunkan kandungan HexA dari pulp dan kertas antara lain dengan mengaplikasikan proses oksidatif kimia pada proses pemutihan atau dengan menggunakan proses enzimatis. Kandungan HexA yang rendah, akan dapat mempertahankan pulp dan kertas dari terjadinya proses penguningan, menghemat konsumsi bahan kimia serta menurunkan kandungan adsorbable organic halides (AOX) pada air limbah.Kata kunci: hexenuronic acid, pemasakan kayu, bilangan Kappa, AOX, enzimatis Hexenuronic Acid Content on Pulp and its Effects on Pulp Quality and Wastewater: a ReviewAbstractThe wood active alkali cooking process will produce hexenuronic acid (HexA) originating from 4-O-methylglucuronoxylan of the glucuronoxylan group in hemicellulose. Hydrolysis process of HexA produces two types of furan compounds, namely 2-furancarboxylic acid (FA) and 5-formyl-2-furancarboxylic acid (FFA). The HexA hydrolysis process contained in pulp and paper resulting from the cooking process is one of the causes of the yellowing process on paper due to exposure to moisture and heat from the environment. In addition, the HexA content of pulp can also increase the consumption of chemicals in the pulp and paper production process, especially in the bleaching process and testing of Kappa number parameters, and can also contribute to the content of organic chlorine soluble compounds in the waste water of the pulp and paper industry. There are several methods for reducing the HexA content of pulp and paper including by applying the oxidative chemical process to the bleaching process or by using an enzymatic process. Low HexA content, will be able to maintain pulp and paper from the occurrence of the pulp yellowing process, save on chemical consumption and reduce the adsorbable organic halides (AOX) content in wastewater.Keywords: hexenuronic acid, wood cooking, Kappa number, AOX, enzymatic

ABSTRAK
Pelaksanaan program deteksi dini kanker serviks dengan metode IVA merupakan kebijakan pemerintah Republik Indonesia dalam upaya mengantisipasi dan menurunkan angka kejadian kanker serviks. Masih rendahnya cakupan deteksi dini kanker serviks pada tahun 2016 di Kabupaten Kampar yaitu hanya 1.165 orang wanita usia subur (wus) dari jumlah sasaran 110.236 orang atau hanya 6% dari target 100%. Tujuan penelitian ini adalah untuk mengetahui bagaimana pelaksanaan program deteksi dini kanker serviks dengan metode IVA. Metode penelitian yang di gunakan adalah metode Kualitatif dengan riset naratif. Analisis data yang di lakukan adalah content analysis dengan Triangulasi. Informan dalam penelitian ini berjumlah 12 orang. Hasil penelitian menunjukan bahwa pelaksanaan program deteksi dini kanker serviks dengan metode IVA sudah terlaksana tapi belum maksimal. Pelaksanaan program di laksanakan oleh Puskesmas serta posyandu dan bidan sebagai tenaga pelaksana hanya 31 orang yang sudah terlatih. Pembiayaan untuk kegiatan deteksi dini kanker serviks ini di bebankan pada Dana Bantuan Operasinal Kesehatan Puskesmas dan dana Jaminan Kesehatan Nasional. Bidan sebagai pelaksana sudah bekerja sesuai SOP yang di tetapkan walaupun masih belum maksimal karena adanya keterbatasan sarana yang ada. Peran linatas sektor baik vertical maupun horizontal sudah cukup baik. Tingkat pengetahuan tentang kanker serviks yang rendah, rasa malu, takut dan khawatir dari WUS sebagai sasaran IVA merupakan kendala yang masih di jumpai dan harus dapat di tanggulangi.
