Survey on Ethno Botany and Medicinal Animals at Sayo and Hawa Gelan Districts of Kelem Wollega Zone, Western Ethiopia

parts like hoof, blood, meat, liver is commonly used with different additives like milk, honey, salt. This study showed the wide use of medicinal plants and animals in Hawa Galan and Sayo District in meeting the primary healthcare needs of the community. Even though there is a wealth of indigenous knowledge transfer is declining from generation to generation as a result of oral transmission. This finding therefore may imply that conducting in-depth scientific studies may help elucidate the science underlying the efficacy of both animals and plants in managing health and this may lead to the discovery of useful Lead compound. Further studies concerning the conservation and management of the animal and plant resources are needed.
Atmospheric negative corona discharge using Taylor cone as a liquid cathode

We examined the characteristics of atmospheric negative corona discharge using a liquid needle cathode. As a liquid needle cathode, a Taylor cone with conical shape was adopted. A micronozzle was filled with liquid, and a plate electrode was placed above the nozzle. By applying a dc voltage between electrodes, a Taylor cone is formed. To change the liquid property, we added sodium dodecyl sulfate to reduce the surface tension, sodium sulfate to increase the conductivity, and polyvinyl alcohol to increase the viscosity, in distilled water. Liquids with a high surface tension such as pure water could not form a Taylor cone. When we reduced the surface tension, a Taylor cone was formed and a stable corona discharge was observed at the tip of the cone. When we increased viscosity, a liquid filament protruding from the solution surface was formed and corona discharge was observed along the filament at a position 0.7–1.0 mm above the tip of the cone. Increasing the conductivity resulted in the higher light intensity of the corona and the lower corona onset voltage. Using a Taylor cone, different types of corona discharge were observed by changing the property of the liquid.
Determination of Some Metals Which are Important for Food Quality Control in Bread

Abstract This study is the small part of the big project related to the metallic contamination in foodstuff. The work presented here allowed determination the level of iron, copper, zinc, lead and cadmium in bread samples obtained from 20 bakeries in Ankara and Samsun, Turkey. The atomic absorption spectrophotometry method was used to determine these metals. The mean values of iron, copper, zinc, lead, and cadmium levels were found as 19·2±8·1 mg/kg-dry weight (dw), 2·1±1·0 μg/kg-dw, 10·0±3·0 μg/kg-dw, 86·8±176·0 μg/kg-dw, and 12·2±6·1 μg/kg-dw, respectively. No significant differences were found in copper and lead levels of samples obtained from bakeries in general, and in copper and cadmium levels of the samples from different provinces ( P >0·05), while they were considered significant in iron, zinc, and cadmium levels of samples in general, and in iron, zinc and lead levels of samples from different provinces ( P
Study of some biochemical markers for patients with leukemia

Background: One of the most common cancers in children is acute lymphoblastic leukemia (ALL). Treatment has been developed, but the treatment still leads to relapse in children. lactate dehydrogenase (LDH) and ferritin play an important role in Acute lymphoblastic leukemia. Aim: Our current study aimed to evaluate serum level of LDH, ferritin, GH and CRP in Iraqi Acute lymphoblastic leukemia patients before treatment (new case) and after achieving clinical remission (after treatment). Patients and Methods: This study included 120 children, including 80 children with Acute lymphoblastic leukemia of both sexes (48 males, 32 females, ages 11 to 18) who were visiting Ibn al-Atheer Children’s Educational Hospital in Mosul, Iraq. Forty uninfected children of identical age (23 males and 17 females) were considered as a control group. In addition, the group of patients was divided into two groups, the first newly diagnosed (before treatment) and the second patients after treatment arrive in a state of remission. Serum lactate dehydrogenase, ferritin, growth hormone and c-reactive protein were measured. Results: The finding of our study showed that the mean age for patients with ALL was 14.1±1.7 years, and the average age of healthy persons is 14.6±1.8 years. The results indicated that Acute lymphoblastic leukemia patients have a significant increase (P Also, the results indicated that ALL patients before treatment have a significant increase (P≤ 0.0001) in level activity of LDH (1260.2±287.0 U/L; 182.5±41.9) ferritin (450.9±171.7ng/ml; 52.1±5.6ng/) and growth hormone (9.4±1.3ng/ml 7.5±2.5 ng/ml) compared to patients after treatment arrive in a state of remission, respectively. While there was no significant difference was shown in the level of LDH, ferritin, LDH and CRP between patients after treatment and healthy children. Conclusion: Serum lactate dehydrogenase and ferritin levels in patients with acute lymphoblastic leukemia at an early stage are significantly increased, while its fall to the normal value in patients at clinical remission. So measurement and surveillance of changes in serum LDH and ferritin levels could be helpful for easy and simple assessing and prognosis of the disease in these patients. Also, changing the level of growth hormone before and after treatment may help in estimating the condition and predicting the response to chemotherapy.
Enzymatic conversion of starch in twin-screw HTST-extruder

Wheat starch was liquefied to DE 25–30 employing heat stable α-amylase and twin-screw Werner & Pfleiderer Continua 58 HTST-extruder. Most significant reduction in batch saccharification time was obtained when starch was liquefied as a slurry containing 60% water at 120°C mass temperature, feed rate 1 500 g min−1, screw rotation rate 250 min−1, and 0.9% (w/w, d.s.) Novo Termamyl 120 L α-amylase was added immediately after initiation of gelatinization in the extruder. Saccharification was carried out at 60°C employing 0.36% (w/w, d.s.) Novo glucoamylase 150 L to reach a DE 96 in 22 h. Best total conversion was, however, obtained when also saccharification was initiated in the extruder by adding glucoamylase just before the die element, after lowering mass temperature to 60°C, and by allowing the saccharification to continue at 60°C after extrusion processing to reach a DE 94 in 5 h and DE 97 in 21 h. Enzymatische Starkekonversion in einem Twin-Screw HTST-Extruder. Weizenstarke wurde bis zu einem DE-Wert von 25–30 DE verflussigt, unter Verwendung hitzestabiler α-Amylase und unter Einsatz eines kontinuierlich arbeitenden Doppel-Schnecken-Extruders deutscher Bauart. Die im Behalter-Verfahren durchgefuhrte Starkeverzuckerung ergab eine signifikante Reduktion der Verzuckerungszeit, besonders dann, wenn die Starke als Starkemilch mit 60% Wassergehalt bei 120°C Massetemperatur, eine Einspeisungsrate in den Extruder von 1 500 g/min und einer Umdrehungszahl der Doppelschnecken von 250 U/min verflussigt wurde und man Novo-Termamyl 120 L-α-Amylase in einer Menge von 0,9% (w/w, TS) so hinzufugte, das der Eintritt des flussigen Termamyls direkt nach Beginn der Starkegelatinierung im Extruder erfolgte. Die Verflussigung der Starke wurde bei 60°C und bei Anwendung von 0,36% (w/w, TS) Novo-Glucoamylase 150 L bis zum Erreichen eines DE-Wertes von 96 in 22 h durchgefuhrt. Die beste Starkeverflussigung bzw. -verzuckerung wurde jedoch dann erreicht, wenn man die Verzuckerung durch Zugabe von Glucoamylase unmittelbar vor die Scherelemente vor der Extruderduse einpumpte und auserdem die Massetemperatur bis auf 60°C absenken konnte und Vorsorge dafur traf, das die Verzuckerung bei 60°C nach dem Extrusionsprozes kontinuierlich fortlaufen konnte, bis ein DE-Wert von 94 in 5 h und ein DE-Wert von 97 in 21 h erreicht war.
A molecular beam investigation of He, CO, and O2 scattering from Pd(111)

Adsorption of CO and O2 on Pd(111) has been studied with the molecular beam technique. Absolute sticking coefficients for CO and O2 have been determined as a function of coverage, angle of incidence, and substrate temperature. Angular distributions of the scattered molecules show that the probability for capture in the precursor state is unity for CO at low coverages and for all substrate temperatures investigated and 0.5 for O2 at low coverages independent of the substrate temperature. Modulated beam experiments show that Edes. for CO is 32 kcal/mole at low coverages. Phase sensitive detection and waveform analysis show that at high CO coverages on the impurity free surface and over a wide range of coverages on a carbon contaminated surface, three distinct CO species are present on the surface.
THE IMPLEMENTATION OF FUN FISHING TO TEACH SPEAKING FOR ELEMENTARY SCHOOL STUDENTS

To produce competitive students that ready to face the trend of language learning in English as a foreign language, especially speaking skills, teachers should be ready to develop good planning in the teaching process. It can be in the form of strategies that can motivate students in the learning process. Moreover, in teaching elementary school students, teachers should be more creative to encourage students’ motivation in speaking by using attractive teaching media which involves physical activity because young learners usually only have a short attention span. By using teaching media, students will learn a language in such attractive and fun ways. Thus, the researchers want to see the use of Fun Fishing in teaching speaking at one of the Elementary Schools in Lampung to encourage students in learning English. This research used a qualitative method since it disclosed how to implement Fun Fishing media in an Elementary School in Lampung. As a result, the students were divided into four groups consisted of 2-3 members and learned English which involved physical activity. To sum up, using this media in learning English can motivate students to speak in English and make teaching and learning become more fun because they did physical activity.
FLOW ANALYSIS AND MARKOV CHAIN MODELLING TO QUANTIFY THE AGITATION EFFECT IN A CONTINUOUS POWDER MIXER

This paper is concerned with the investigation of the mixing process in a pilot scale continuous powder mixer, from both experimental and modelling points of view. A Markov chain model is proposed to simulate the residence time distribution (RTD) obtained from tracer experiments and detection by image analysis. The general model consists of 10 continuous stirred tank reactors with identical exchange coefficients and may serve as a basis for other applications. A 2D chain model is also developed and applied to take into account more features of real flow, such as crosswise mixing. Agreement between the model results and experimental data is more than reasonable, and gives a clear physical meaning to the parameters introduced. The characteristics of the process are controlled by the rotational speed of the mixer, which appears to be the key scale-up variable along with stirrer design.
Overconfidence Bias in Working Capital Management and Performance of Small and Medium Enterprises: The Perspectives of Ghanaian SME Managers

Although managerial overconfidence is receiving substantial attention in economic analysis, explanations so far mostly focused on corporate executives and corporate investment and financing decisions. This study investigates SME managers (owners) overconfidence behavioral bias in working capital management and performance. A qualitative case study was employed to explore the perspectives of 35 SMEs managers from trading and manufacturing firms. Data were obtained through Semistructured interviews. Based on the thematic analysis, the study found superior financial ability, perfect industry knowledge and optimism in business success to be SMEs overconfidence behaviors and their influence on working capital management and performance resulted in aggressive working capital investment and financing and expected higher performance. Specifically, overconfident SME managers is more likely to overinvest in working capital inventory for expected higher profits if they have access to sufficient internal capital. However, they are less likely to invest more in firms with substantial working capital investment in inventories if expected sales revenue are below expectation. We argued that, overconfident matters so it is not enough to study working capital management and performance of SMEs without considering manager’s biases.

The Impact of Corporate Governance on Earning Quality: Empirical Evidence From Pakistan

This study investigates and analysed the very important corporate finance area the impact of corporate governance on earning quality. This study consist of firms from food, agriculture, pharmaceuticals and manufacturing sectors listed on the PSX. The total sample taken for analysis is 107 companies belongs from multiple manufacturing sectors. The data covers a time span of 10 years from 2007 till 2016. This study is based on the secondary data which is collected from PSX and individual company portals. The overall results of the study have shown mixed results as multiple variables of corporate governance have been regressed during the study. Board size, CEO duality, Board composition, Board independence, Frequency of board meetings, Audit Committee size, Audit committee meeting and Audit quality have been taken to measure the impact of corporate governance on two variables of earning quality which are earning persistence and earning predictability. The overall results have shown very positive impact of audit meeting and board composition on earning quality. On the other hand CEO duality and board size have shown very negative impact on earning quality. Future researchers have also room for new research areas. Recommendations in contrast of the conclusions of the research this study recommends that the above mentioned sectors can improve their performance and quality of earnings by applying the timely audit meetings and composing a board which have combination of outside directors. The CEO duality must be eliminated as it can be harmful for earning quality.
A Raman and Computational Study of Two Dithienyl Naphthodithiophenes: Synthesis and Characterization of New Polymers Showing Low Band Gap Optical and Electroactive Features

Two isomeric dithienyl naphthodithiophenes and their corresponding polymers have been thoroughly studied by using a combination of spectroscopic, electrochemical, and quantum chemistry techniques. The change between the syn and anti configuration of the sulfur atoms of the core translates into important differences in their optical and electrochemical properties. This study reveals the existence in the syn isomer of a bonding interaction, while in the anti isomer there exists a more delocalized π-electron distribution. The full assignment of the Raman spectra of the monomers has allowed to interpret, assign, and correlate the spectra of the polymers. Upon polymerization the Raman data indicate an increment of the bond length relaxation pattern for the electronic structure of the polymer regarding the monomers. The two polymers are surprisingly strong amphoters, showing very stable oxidation and reduction waves at relatively low potentials at the same time that they behave as low band gap polymers. From a .
Influence of Various Parameters on the Air Separation Process by Magnetic Membranes

Polymer membranes filled with magnetic powder and magnetized, used for an air enrichment, are investigated. Various polymer matrix with different types and granulation of dispersed magnetic powder were used for the preparation of the membranes. All membranes were examined for N2, O2, and air permeability. Mass transport coefficients were evaluated basing on Time Lag methods and D1-D8 system. Structure and morphology of the obtained membranes were investigated using fractal analysis. Box counting method for calculating generalized fractal dimension was applied. Obtained results allowed to optimize the preparation procedure of magnetic membranes with the best permeation properties.
Soft synthesis of single-crystal copper nanowires of various scales

Single-crystal copper nanowires (Cu NWs) have been synthesized by a series of simple hydrothermal methods. In this study, we will give several soft synthesis routes to fabricate low-dimensional nanocrystals with focus on various kinds of nanowires. Especially, Cu NW products with diameters around 6–10 nm and lengths below 1 μm can be obtained by using mesoporous silica (SBA-15) powders as templates through vapor infiltration of a reducing agent (dimethylamine borane, DMAB) under mild conditions; ethylene glycol reduction of copper nitrate at 160 °C in the presence of polyvinyl pyrrolidone (PVP, K-30) to prepare uniform copper nanowires, the average diameter of products is 30–50 nm and their lengths vary between 5 and 20 μm; moreover, the products with Cu@C core–shell structure of 70–130 nm diameters and lengths longer than 10 μm have been synthesized by using glucose as the reducing agent and the source of carbonaceous shells to react with copper(II) sulfate trihydrate (pentahydrate) under cetyltrimethylammonium bromide (CTAB) inducement. The morphology, microstructure and composition of the copper nanowires were characterized by scanning electron microscopy (SEM), tunneling electron microscopy (TEM) and X-ray diffraction (XRD). The effects of the different reaction conditions were investigated and their possible growth mechanisms are discussed. Beyond, so-called “soft” methods are soft-chemical, straightforward, and general approach, which have advantages for the synthesis of metal nanowires in large amounts.
Essential Oil Composition of Eucalyptus camaldulensis Dehn. from Mozambique

Abstract Water-distilled oil from the dried leaves of two trees of Eucalyptus camaldulensis Dehn. of different ages, were analyzed by GC/MS. The principal constituent, in the 4-year-old tree oil and the 11-year-old tree oil, was 1,8-cineole (40.0%, 37.1%, respectively). Other major constituents were: β-pinene (9.2%, 0.1%), γ-terpinene (5.3%,10.4%), p-cymene (4.7%, 11.6%), terpinen-4-ol (2.8%, 5.5%) and globulol (5.4%, 9.6%).
Conserving Manurial Nitrogen

ABSTRACT NITROGEN in manure can be lost by ammonia volatilization, nitrate leaching, and denitrification. Such loss can reduce the value of manure as a source of crop nutrients. This paper reviews past practices in attempting to conserve nitrogen by adding chemicals to manure. Results of two recent experiments are reported. In one, three chemicals—gypsum, super-phosphate, and phosphoric acid—were added to manure to produce a stable ammonium compound. Results indicated that superphosphate and phosphoric acid are effective in conserving ammonia but are not cost effective. In the second study a nitrification inhibitor was found to be effective in conserving manurial nitrogen—especially for manure applied in the fall.
Improving Iranian Intermediate EFL Learners’ Oral Narrative Task Performance in Terms of Accuracy, Fluency and Complexity by Awareness Raising Through Semantic Fields

The effects different awareness-raising techniques might have on language learners’ performance have been studied by many researchers. The present study specifically focused on improving EFL learners’ oral narrative task performance in terms of accuracy, fluency and complexity by awareness raising through semantic fields. The participants in the study included 40 intermediate learners whose initial homogeneity in terms of language proficiency was assessed via a Preliminary English Test (PET). They were further randomly assigned as one experimental group and one control group, each comprising 20 participants. The amount of instructional time was 17 sessions, during which the participants in the experimental group received an awareness raising technique through 'semantic fields'. Before and after the treatment, an oral narrative test was administrated. The results of the data analysis revealed that the experimental group which received the awareness raising technique outperformed the control group in three measures of accuracy, fluency and complexity on their performance. The participants showed significant improvements in language proficiency as they retold the narratives. The findings of the present study can create the floor for researchers to go deep through the EFL contexts and find more about the probable effects awareness raising techniques might have on language learning and teaching.
Linguistic Devices of Identity Representation in English Political Discourse with a Focus on Personal Pronouns: Power and Solidarity

The present study was aimed at exploring the use of pronominal reference for identity representation in terms of power and solidarity in English political discourse. The investigation was based on a corpus of four political interviews and debates amounting 26,500 words. The analysis was both qualitative and quantitative. In the qualitative analysis, a discourse-analytic approach was used to find out the pronouns, their references and their identity load, and in the quantitative analysis, the distribution of different representations of identity were calculated. A nonparametric test, that is, Chi-Square was run in SPSS as the statistical operation needed for the current study. The analysis showed that most of the personal pronouns represented identity in the form of solidarity. The results also showed that political figures use I-pronoun and its variants to represent their identity in terms of power. The representation of identity in terms of power was also found to be correlated with the use of certain terms such as veto and active voice constructions. Furthermore, the results showed that when making claims, instead of giving pronominal reference to self, political figures use first-person plurals. In order to show solidarity, the speakers may also make use of discoursal proximity. Considering the important role that discourses play in constructing reality, it is important for CDA researchers to reveal sources of power, inequality and prejudice in discourses and interpret their hidden meanings. Pronominal choice and academic voice as linguistic constructions that are ideologically loaded need to be brought into the spotlight.
Rock Fragments in Trichloroethene Microcosms for Bedrock Aquifers

ABSTRACT The purpose of this study was to evaluate microcosm methods that can be used to predict the in situ anaerobic reductive dechlorination of trichloroethene (TCE) in bedrock aquifers with and without amendments. Microcosm conditions (e.g., surface area:volume ratio, initial TCE concentration [C 0], incubation temperature) were selected to simulate in situ conditions at the site. The effect of rock media in the microcosms as a source of surface area and nutrients was also assessed. Comparison was made between microcosms constructed with sterile rock media and rock media submerged for 45 days in a groundwater well within a TCE plume for field colonization. Statistically significant biotic degradation of TCE was observed in microcosms with both groundwater only and non-field-colonized rock media, when amended with lactate. Measured half-lives were similar to half-lives observed in field conditions. Normalizing biotic results to abiotic results provides a method that deducts the abiotic losses and allows complete comparison between sample rounds, assuming samples were randomly selected for analysis within the sample round to avoid systematic errors or variation.
