Taibai Materia Medica: Unofficial ‘Herb Physicians’ in North Western China
Authors: Springer Lena
Published: April 2019

Dans les montagnes du Nord-ouest de la Chine, traversées par de rares chemins et couvertes de forêts et de rochers, la cueillette des plantes médicinales est surtout assurée par des "phytothérapeutes" (caoyi) autodidactes travaillant à mi-temps. Aux alentours du Mont Taibai, le point culminant de la Chine des Han, ces phytothérapeutes revendiquent la légitimité géopolitique sur leur materia medica. Selon ces détenteurs non-officiels de savoirs, le Mont Taibai, en raison de son climat complexe, offre la panoplie complète des matières médicales chinoises, auxquelles ils ont ajouté des espèces locales précieuses. De façon collective, ils pratiquent la cueillette, la culture et le stockage des matières médicales qu'ils présentent et exportent comme "materia medica du Taibai". Cette représentation a entraîné des changements dans leur statut. Une des modalités de ces changements consiste en la régulation officielle grâce à la botanique de la production et du commerce des plantes médicinales. Une autre est la préservation du patrimoine culturel reposant sur les lignées taoïstes.

Published: April 2019

The purpose of this work is to investigate the effect of anteriorly-added mass to simulate pregnancy on lower extremities kinematic and lumbar and thoracic angles during stair ascending and descending. 18 healthy females ascended and descended, with and without a pseudo-pregnancy sac of 12 kg (experimental and control groups, respectively), a costume-made wooden staircase while instrumented with 20 reflective markers placed on the lower extremities and the spine. The movements were captured by 12 infrared cameras surrounding the staircase. Tracked position data were exported to MATLAB to calculate the required joints angles. SPSS was used to compare the ascent and descent phases of control group, and to find if there are any significant differences between control and experimental groups in the ascent phase as well as in the descent phase. When comparing the ascent and descent phases of control group, data revealed a higher hip flexion during ascending and greater ankle planter-flexion and dorsiflexion, lumbar, and thoracic angles during descending; however, no significant difference was shown in the knee flexion angle between ascending and descending. Non-pregnant data showed greater maximum hip flexion and ankle dorsiflexion during stair ascending compared to simulated-pregnant group; while ankle planter-flexion, knee flexion, and lumbar angle were greater for simulated-pregnant status. During stair descending, non-pregnant group had greater minimum hip flexion and ankle dorsiflexion compared to simulated pregnant group; while ankle planter-flexion, knee flexion, and maximum hip flexion were greater for simulated-pregnant group. However, the lumbar and thoracic angles were found to be similar for simulated-pregnant and non-pregnant groups during stair descending. In conclusion, the current study revealed important kinematic modifications pregnant women adopt while ascending and descending stairs at their final stage of pregnancy to increase their stability.

Subtyping of non-small cell lung cancer by cytology specimens: A proposal for resource-poor hospitals
Authors: Celik Betul , Bulut Tangul , Khoor Andras
Published: April 2019

Aim:

Cancer diagnosis and treatment depend on pathology reports but naming a cancer is sometimes impossible without specialized techniques. We aimed to evaluate the sensitivity of cytological sub-classification of non-small cell lung carcinoma, not otherwise specified group (NSCLC-NOS) into Adenocarcinoma (AC) and Squamous cell carcinoma (SqCC) without using immunohistochemistry.

Methods:

Endobronchial ultrasound guided fine-needle aspiration biopsies and cytology slides diagnosed as NSCLC-NOS between 2004- 2008 were reviewed retrospectively. The final diagnosis was reached by immunohistochemistry (TTF-1, p63) when necessary.

Results:

One hundred-twenty nine cases were retrieved. The final diagnoses were as follows: SqCC: 30.3%; AC: 65.7%; combined tumor (3 adenosquamous and 1 small cell + SqCC): 4%. Cytological diagnoses rendered were as follow: Definitely SqCC: 10.1%; favor SqCC: 14.1%; definitely AC: 38.4%; favor AC: 35.4%; NSCLC-NOS: 2%. The sensitivity and specificity of cytology were 86.3 and 87.5% for AC diagnosis respectively.

Conclusion:

Positive and negative predictive value of cytology was 95.3% and it was even 100% for well to moderately differentiated tumors. There was a tendency to sub-classify poorly differentiated SqCC as AC. Papanicolaou stain increased the diagnostic accuracy of SqCC. The combined tumor rate was 4% and after recognizing a tumor component, the second component was missed if the slide examination was terminated prematurely.
Comparative analysis of virulence factors & biotypes of Gardnerella vaginalis isolated from the genital tract of women with & without bacterial vaginosis
Authors: Nisha Kumari , Antony Beena , Udayalaxmi Jeppu
Published: April 2019

Background & objectives:

Bacterial vaginosis (BV) involves the presence of a thick vaginal multispecies biofilm, where Gardnerella vaginalis is the predominant species. The reason for an increase in the number of G. vaginalis which are usually present as normal flora of the female genital tract in cases of BV, is not known. Hence, the objective of the present study was to compare the biotypes and virulence factors of G. vaginalis isolated from the genital tract of women with and without BV.

Methods:

High vaginal swabs collected from 811 women of reproductive age were cultured. G. vaginalis isolates were biotyped and tested for adherence to vaginal epithelial cells, biofilm formation, agglutination of human red blood cells (RBCs), protease production, phospholipase production and surface hydrophobicity.

Results:

Of the isolates from women with BV, 83.3 per cent (60/72) showed good adherence, 78.4 per cent (58/74) produced biofilm, 82.9 per cent (63/76) produced phospholipase, 67.1 per cent (51/76) produced protease, 77.3 per cent (58/75) were positive for surface hydrophobicity and 61.6 per cent (45/73) were positive for haemagglutination of human RBC. In case of G. vaginalis from non-BV women, 25 per cent (15/60) isolates showed good adherence, 18.4 per cent (9/49) biofilm production, 35 per cent (21/60) phospholipase, 36.6 per cent (22/60) protease, 41.7 per cent (25/60) surface hydrophobicity and 10.1 per cent (6/59) agglutination of human RBCs. Maximum number of isolates belonged to biotypes 6, 2 and 3. Biotype 3 was more associated with non-BV rather than BV; biotype 6, 2 and 1 were more associated with cases of BV. Maximum virulence factors were expressed by biotypes 6, 2 and 1.

Interpretation & conclusions:

Virulence factors were more expressed by G. vaginalis isolates obtained from women with BV rather than from non-BV. Biotypes 6, 2 and 1 were more associated with cases of BV and expressed maximum virulence factors.
Comparative study of alloimmunization against red cell antigens in sickle cell disease & thalassaemia major patients on regular red cell transfusion
Authors: Jariwala Keyuri , Mishra Kanchan , Ghosh Kanjaksha
Published: April 2019

Background & objectives:

Sickle cell disease (SCD) patients require red cell transfusion during different clinical complications of the disease. Such patients are at a high risk for developing alloantibody against red cell antigens. From India, there are limited data available on alloantibody formation in multiply transfused SCD patients. The present study was thus undertaken to fill up this lacunae by looking at the development of red cell alloantibodies in SCD and β-thalassaemia patients on regular transfusion.

Methods:

All sickle cell disease patients undergoing red cell transfusion between 2008 and 2016, were included. During this period, a large number of β-thalassaemia major patients also underwent regular red cell transfusion. These thalassaemia patients were also included to compare the tendency of antibody formation between SCD and β-thalassaemia major patients. All patients before regular transfusion were regularly assessed for the development of red cell antibody. Red cell antigen, antibody screen crossmatch and antibody identification were done using the standard technique.

Results:

A total of 138 patients with SCD aged between 4 and 53 yr (mean 17.6 yr) consisting of 83 males and 55 females (male:female, 1.5:1) along with 333 transfusion-dependent β-thalassaemia patients were studied. Over the last eight years, 15 patients with SCD and four patients with thalassaemia developed alloantibody (P<0.001). Antibody specificity of their alloantibodies was against Rhc, RhE, Kell, Fya and Fyb only. Sickle cell disease patients with and without alloantibody required on the average 11.8 and 8.6 units of red cell concentrate, respectively (P<0.05).

Interpretation & conclusions:

About 11 per cent of the transfused sickle cells patients developed alloantibodies. The antibody specificity was restricted to Rh, Kell and Duffy blood group systems. Extended antigen matching involving Rh, Kell and Duffy antigens may prevent alloantibody in such patients.
Constrictive Pericarditis in Association with Ischaemic Heart Disease
Authors: Shah Rajesh Krishnachandra
Published: April 2019

Constrictive pericarditis (CP), a not so common condition, has symptoms and signs of heart failure and abnormal echocardiographic findings, such as jerky septal motion. These findings can be mistaken for ischemic heart disease (IHD) if the echocardiographer is inexperienced. Although the etiology of CP can be varied such as idiopathic, postviral, tuberculous, postsurgical, and radiation-induced the final common pathway is the development of fibrous thickening or calcification of the visceral pericardium resulting in pericardial noncompliance, and ultimately requiring surgical intervention. As CP is potentially reversible and surgically curable condition, with improvement in symptoms and quality of life, the diagnosis should not be missed. Here, we present a case in which the diagnosis of CP was made, and subsequently found to have IHD also.
Right-Sided Constrictive Pericarditis: A Rare Variant of an Uncommon Disease
Authors: Oswal Mehul Popatlal , Ponde Chandrashekhar Kashinath
Published: April 2019

Constrictive pericarditis (CP) is characterized by thick pericardial fibrosis and calcification that causes progressively impaired diastolic filling of the heart with associated symptoms of heart failure. Rarely, it can also present as localized CP and depending on the CP location, clinical presentation can be variable, including compression and obstruction of right ventricular inflow tract, coronary obstruction, or pulmonary stenosis. We report a rare case of isolated constriction of the right side of the heart due to loculated tuberculous pericardial effusion.

Authors: Kudryavtsev O E
Published: April 2019

В настоящей работе обосновывается сходимость формул приближенной факторизации Винера-Хопфа к точным формулам для факторов для широкого класса процессов Леви. Другим результатом статьи является анализ сходимости методов Монте-Карло, основанных на рандомизации времени и явных формулах факторизации Винера-Хопфа.
В статье предлагаются два обобщенных подхода к построению метода Монте-Карло в случае моделей Леви, не допускающих явную факторизацию Винера-Хопфа. Оба метода используют приближенные формулы для факторов Винера-Хопфа. В рамках первого подхода симуляция процессов супремума и инфимума в экспоненциально распределенные моменты времени осуществляется на основе обращения их приближенных функций распределения. Второй подход не требует разбиения траектории на части, предполагает непосредственную симуляцию конечных значений процесса инфимума (супремума) и может быть использован для симуляции совместного распределения положения процесса Леви и соответствующего процесса экстремума.

Sobre o estatuto e estrutura sintática das condicionais de se factuais do Português de Moçambique
Authors: Justino Víctor Mércia
Published: April 2019

Este artigo discute o estatuto e a estrutura sintática das condicionais factuais de se do português de Moçambique. Os resultados da aplicação de testes sintáticos às factuais mostram que podem ser integradas ou periféricas. Deste modo, são distintas das factuais de outras línguas, como o inglês, que são consideradas apenas periféricas (HAEGEMAN, 2003; BHATT; PANCHEVA, 2006). Do ponto de vista estrutural, as integradas ocupam uma posição relativamente baixa que é a de adjunção a VP e as periféricas, pelo contrário, posições altas na frase, em adjunção a CP ou TP (HAEGEMAN, 2003; LOBO, 2003). Para darmos conta das integradas antepostas, com base em argumentos empíricos, defendemos que são geradas por Move do interior do TP da matriz, onde são geradas, para a posição de especificador de tópico, por topicalização da oração adverbial condicional, na linha de Duarte (1987, 1996) e Valmala (2009), contrariando a hipótese de que são geradas por Merge (LOBO, 2003; IATRIDOU, 1991).

Authors: Al-rsa’i Mohammed S. , Shugairat Mohammed F.
Published: April 2019

This study aimed to investigate how to implement Differentiated instruction in Science teaching by using technology. The analytical approach was used and the results showed that technology enhanced Differentiated instruction because of the diversity of technology tools and programs. Moreover, the use of technology in Differentiated instruction requires the hiring of (TPACK) model (Technological Pedagogical content Knowledge) regarding the interrelationship between content, teaching and technology. Technology also helps in applying Differentiated instruction of Science through identifying students’ interests, and the degree of readiness, along with the appropriate learning patterns for each of them. The study recommends training science teachers how to implement the Differentiated instruction by using technology, and sensitize them to (TPACK) model increasing opportunities of including this model in the science curriculum.
Validation of the Grammaticality Judgment Test of Korean Passive Expressions Through Exploratory Factor Analysis
Authors: Kim Hojung , Lee Wonki
Published: April 2019

This research project implemented an exploratory factor analysis (EFA) of the construct validity of a grammaticality judgment test (GJT) as a tool to measure Korean language learners' grammatical knowledge. Focusing on passive expressions in Korean, we developed two distinctive tools for implicit and explicit knowledge, along with three types of GJTs with different variables of time, modality, and stimuli. The EFA with two latent variables was implemented to examine how the test types would be grouped according to components. The results revealed that ungrammatical and grammatical sentences in each test converge to different factors, suggesting that the measurement of the learner's knowledge type may depend on grammaticality of stimuli. The results highlight the importance of carefully controlling the grammaticality of sentences as a factor in designing GJTs.

Risks Faced by Islamic Banks: A Study on the Compliance Between Theory and Practice
Authors: Rhanoui Salma , Belkhoutout Khalid
Published: April 2019

Risk management is an active field where applications are reconsidered after each obstacle. Islamic banks are not excluded from this rule, particularly when they operate in a global financial system, in which they are occasionally forced to follow conventional banking rules. Nevertheless, Islamic banks are part of a less-advanced industry and face many challenges when handling risk. In theory, Islamic banks are confronted with two categories of risk: common risks, which are similar to the risks faced by conventional banks and risks specific to Islamic banks, due to their specificities and methods of operation. However, practice does not necessarily reflect this dichotomy. Therefore, the purpose of this paper is to make a compliance study between the theory and practice of Islamic banking risks. More precisely, it will compare all the risks fully recognized by the theory to the risks that are actually managed by the Islamic banks in their activities, using a sample of these institutions. The results of this qualitative approach, demonstrate that practice can be quite different from theory.
Escola como ambiente social: integração da história e geografia no ensino fundamental i e as experiências pessoais
Authors: De Carvalho Andressa Coelho Righi , Henning Leoni Maria Padilha
Published: April 2019

Esse artigo foi desenvolvido em torno das ideias de alguns autores, em especial, John Dewey, em cujo referencial teórico foi acrescido o pensamento de Anísio Teixeira, dentre outros, o que nos permitiu entender a realidade educacional atual, considerando as experiências de Dewey na Escola Laboratório de Chicago e as de Teixeira na Escola Parque em Salvador. Nosso interesse, nesta oportunidade, é investigar se tais experiências educacionais dialogam com a realidade vivenciada no Ensino Fundamental I, especificamente na integração entre as disciplinas História e Geografia. Obtivemos, com essa pesquisa, a percepção do quanto não deva ser endereçada à formação apenas a obtenção e aumento de conteúdo a partir de uma perspectiva “massificadora”, e sim que as propostas formativas devam favorecer o desenvolvimento individual, tornando as pessoas capazes de pensar e refletir amplamente, incluindo no rol dos seus interesses as questões que afetam a sociedade em que vivem. Foi o que pudemos aferir ao analisar o trabalho desenvolvido tomando por base a integração das disciplinas em apreço neste estudo. Vimos ainda a necessidade de a escola não ser considerada uma vida paralela à vida social ou vista como uma experiência isolada idealisticamente, mas que os jovens devam viver sua vida de modo independente e autônomo em qualquer situação em que se encontrem, relacionando as experiências externas com aquelas que obtenham na escola, sendo estas mais bem organizadas e selecionadas em prol de sua formação com vistas ao bem comum.
A transição da educação infantil para o ensino fundamental: uma teoria para orientar o pensar e o agir docentes
Authors: Mello Suely Amaral
Published: April 2019

Com este artigo, quero problematizar a necessidade de uma formação teórica sólida dos professores e professoras também da educação infantil e do ensino fundamental numa perspectiva de educação que promova o desenvolvimento humano. Dada a nova compreensão do papel da educação na constituição do humano em cada um de nós, a intencionalidade docente se faz essencial para enfrentar o desafio colocado por Gramsci (1979) à escola e ao professor ou professora: formar cada criança para ser um dirigente. Para isso, trago algumas contribuições da teoria histórico-cultural para compreender o desenvolvimento humano e busco as implicações desta concepção, o que reforça a importância da apropriação/construção substancial de uma teoria pedagógica por parte dos docentes que possa orientar seu pensar e concretizar-se sob a forma de práticas pedagógicas desenvolventes.
Contributos para uma análise crítica do discurso oficial sobre educação literária

Published: April 2019

Neste texto, pretendemos apresentar alguns contributos para a análise do discurso oficial que emerge da transposição do conceito de educação literária para os textos normativos referentes à disciplina de Português, no Ensino Básico, em Portugal. Assim, procuramos discutir, num primeiro momento, o próprio conceito de educação literária, para, em momento seguinte, o articularmos com a problemática da leitura literária. Procuramos igualmente, ainda no quadro da reflexão teórica, destacar a relação entre a leitura literária e a subjetividade do leitor. Posteriormente, procedendo a análise documental dos acima referidos textos normativos, apresentaremos uma leitura analítica e crítica do discurso oficial. Concluímos que parece existir uma desadequação entre os objetivos de uma efetiva educação literária e o Programa e Metas Curriculares de Português com possíveis implicações negativas no possível leque de práticas adotadas em sala de aula.
Effect of Soy Concentrate, Oat (Avena sativa) Flour and Chia Seeds (Salvia hispanica) as a Partial Substitute of Wheat Flour (Triticum aestivum) on Protein Content, Dietary Fiber Content, Textural Shelf Life and Organoleptic Properties of Breadsticks
Authors: Rendón Mariel Angélica Reyes , Carrillo Esther Pérez , Flores Sara Guajardo
Published: April 2019

Few studies have examined the effects on nutrient contents and organoleptic properties of substituting wheat flour by protein dense ingredients as are soy protein concentrate, oat and chia in bakery formulas. The objective of the study was to assess the effect of adding soy protein concentrate, oat and chia to two breadsticks formulas proposed to provide at least 10 % of the daily recommended value of protein for an adult. Thirty three percentage of wheat flour were substituted by 3:1 oat:chia (BO) and 1:1 oat:chia (BC) composite flours. The analyzed parameters were wheat-meal fermentation time, moisture, protein, insoluble and soluble dietary fiber, firmness, organoleptic acceptance, and preference. Results revealed that both formulas contributed the minimum wished protein content, had higher dietary fiber content than only wheat flour breadsticks and had an acceptable texture, flavor, and appearance. It is recommended to continue formula BO because it turned out to be the favorite in the preference test.

APYRASEs, which directly regulated the intra- and extra-cellular ATP homeostasis, plays a pivotal role in the regulation of the adaptations to various stresses in mammals, bacteria and plants. In the present study, we identified and characterized the wheat APYRASE family members at the genomic level. The results showed that a total of eight APY homologs with conserved ACR domains were identified. The wheat APYs were further analyzed bioinformatically of their sequence alignment, phylogenetic relations and conserved motifs. Although they share highly conserved secondary structure and tertiary structure, the wheat APYs could be mainly categorized into three groups, according to the phylogenetic and structural analysis. Further, these APYs exhibited similar expression patterns in the root and shoot, among which TaAPY3-1 and TaAPY3-3 had the highest expression level. The time-course expression patterns of the eight APYs in the wheat seedlings in response to the biotic stress and abiotic stress were also investigated. TaAPY3-2, TaAPY3-3, and TaAPY6 exhibited strong sensitivity to all kinds of stresses in the leaves. Some APYs showed specific expression responses, such as TaAPY6 to the heavy metal stress, and TaAPY7 to the heat and salt stress. These results suggested that the stress-inducible APYs could have potential roles in the regulation of the adaptation to the environmental stresses. Moreover, the catalytic activity of TaAPY3-1 was further analyzed in the in vitro system. The results showed that TaAPY3-1 protein exhibited high catalytic activity in degradation of ATP and ADP, but not GTP, CTP and TTP. It also has an extensive range of temperature adaptability, but rather preferred relative acid pH conditions. In this study, the genome-wide identification and characterization of the APYs in wheat could be useful for further genetic modifications to generate high-stress tolerant wheat cultivars.

On the secrecy performance of transmit-receive diversity and spatial multiplexing systems
Authors: Maichalernnukul Kiattisak
Published: April 2019

Emerging from the information-theoretic characterization of secrecy, physical-layer security exploits the physical properties of the wireless channel for security purpose. In recent years, a great deal of attention has been paid to investigating the physical-layer security issues in multiple-input multiple-output (MIMO) wireless communications. This paper analyzes the secrecy performance of transmit-receive diversity system and spatial multiplexing systems with zero-forcing equalization and minimum mean-square-error equalization. Specifically, exact and asymptotic closed-form expressions are derived for the secrecy outage probability of such MIMO systems in a Rayleigh fading environment, and the corresponding secrecy diversity orders and secrecy array gains are determined. Numerical results are presented to corroborate the analytical results and to examine the impact of various system parameters, including the numbers of antennas at the transmitter, the legitimate receiver, and the eavesdropper. These contributions bring about valuable insights into the physical-layer security in MIMO wireless systems.
Extinction and the U.S. Endangered Species Act
Authors: Greenwald Noah , Suckling Kieran F. , Hartl Brett , A. Mehrhoff Loyal
Published: April 2019

The U.S. Endangered Species Act is one of the strongest laws of any nation for preventing species extinction, but quantifying the Act’s effectiveness has proven difficult. To provide one measure of effectiveness, we identified listed species that have gone extinct and used previously developed methods to update an estimate of the number of species extinctions prevented by the Act. To date, only four species have been confirmed extinct with another 22 possibly extinct following protection. Another 71 listed species are extinct or possibly extinct, but were last seen before protections were enacted, meaning the Act’s protections never had the opportunity to save these species. In contrast, a total of 39 species have been fully recovered, including 23 in the last 10 years. We estimate the Endangered Species Act has prevented the extinction of roughly 291 species since passage in 1973, and has to date saved more than 99% of species under its protection.
A Scale to Measure Farmers’ Risk Perceptions about Climate Change and Its Impact on Agriculture
Authors: Raghuvanshi Rupan , Ansari Mohammad Aslam
Published: April 2019

Climate change has emerged as one of the key determinants of agricultural productivity. Risks perceptions of farmers’ towards climate change and its impact on agriculture are said to be a strong predictor of their behavioural intentions to climate change mitigation and adaptation strategies.  Consequently, measuring farmers’ perception about risks associated with climate change is of paramount importance and needs to be studied so that appropriate adaptation measures could be undertaken to mitigate the productivity losses. The present study was an attempt to develop a scale to measure the farmers risk perception about climate change which could be used by researchers. Likert’s summated rating technique was followed for the construction of perception scale. The process started with selection of 30 statements on the bases of Mean Relevancy Weightage (MRW) scores; and the statements were given to 30 farmers in four purposively selected villages (based on their degree of vulnerability to climate change as determined by a State government Report) in Kumaon division Uttarakhand, a North Himalayan state of India which is perennially susceptible to climate change risks and uncertainties. The scale developed finally consisted of 20 statements. The reliability and validity of the scale was computed to find out the precision and consistency of the results. This scale will be useful for researchers and academicians studying farmers’ perceptions towards climate change and its impact on agriculture. It would also be useful for policy makers for developing risk management strategies.

Municipal Solid Waste management is one of the most fundamental issues in the contemporary urban environments particularly in developing countries like Ethiopia. A huge generation of waste coupled with unbalanced waste management services is the major challenges facing the City of Addis Ababa. A continuous increase of production of more wastes and change in the composition of waste into complex, the waste management practice is challenged by low prioritization of waste management, limited revenues for financing waste management with the ever increasing population of this city. This retrospective study received documents from books, thesis works, annual waste management conference reports, journals on waste management, newsletters, abstracts and proceedings which can properly address the main factors that strongly hinder proper waste management and the extent to which community is aware of appropriate waste disposal systems in Addis Ababa city. The mechanism of Addis Ababa city Sanitation, Beautification and Park Development Authority to coordinate stakeholders has played a vital role in waste management. However, the daily monitoring of waste management by the community development section has not been sufficient because of poor governance where accountability, participation and transparency are lacking. It is also unauthorized solid waste dumping practice problem in different locations and has an effect on water sources and its resources. Effective involvement of both private and public sectors should improve waste management and provide door-to-door collection, street sweeping and facilitate drainage disposable canals. Therefore, an integrated solid waste management practice should be implemented for the City and also for the surrounding environment. As a result, strong political will, multi-sectoral approach, public awareness and participation, strategic planning, adequate funding and the adoption of Integrated Solid Waste Management is recommended SWM system required in Addis Ababa city.

Biobased energy and fuels are among the exercisable sustainable energy options mankind has in the not-so-distant future as issues pertaining to global warming and shortfall in fossil fuels loom dark over the planet. The environmental necessity to stop this development by switching to alternative strategies nowadays is generally undisputed. Biofuel made from biomass provide unique environmental economic strategic benefit and can be considered as safe and by and large, the cleanest liquid fuel alternative to fossil fuels. Biofuel produced from Agricultural waste biomass like cocoa (Theobroma cacao L) pod husk shows many potentials advantages in comparison with sugar or starch-based stocks since the latter materials are also food for human and animals. However, the complex nature of this biomass necessitates the use of genetic techniques to produce engineered organisms that are able to transform this polymer into the desired product. With Bioinformatics tools using NCBI BLAST programme, two genes XL1 and XL2 encoding pentose utilization were isolated from the genomic DNA of Pichia stipitis (CBS 6054) and two primers each were designed to span the full coding region of these genes with attached enzymes restriction sites using DNA strider 1.4f7 and Macplasmap programmes. PCR reactions were carried out on 120hg of the isolated genomic DNA for 30 cycles using the DNA Gotaq polymerase enzyme. The amplified PCR fragments were introduced into plasmid vectors pGAPZA and pVT100-U respectively and the constructs were then used to transform the selected ethanol-producing strain of S. cerevisiae (BY4743) isolated from degrading cocoa pod husk biomass meant to serve as starter for biofuel production from cocoa pod husk hydrolysate.
