Acting towards this end the democratic government of Ethiopia (African continent) has recently launched a resettlement program. The main objective of this study is to provide an overall view of the resettlement program in Bamluk and Sawatamp settlement sites, Jawi district, Amhara Regional State of Ethiopia. A qualitative method of analysis was employed for conducting this study. The informants at the household level were randomly selected to give the possible representative information. Key informants interviews and focus group discussions with resettlers and government representatives at district and zonal levels were held. The study revealed that there is a gap between the program document and its implementation on the ground. There was no consistency with the pillars, key principles, and approaches in the program document. The resettlement’s adverse consequences were the lack of proper preparation. The study indicates that the establishment of infrastructure and social services before the resettlement program are below the minimum standard and the services have not yet been improved in the area. Moreover, small land holdings and the risk of exposure to malaria contributed to the failure of the program. This reveals that the implementation of the resettlement program in the area is very weak.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea of storing information and performing complicated calculations with the help of bits, i.e., 0 and 1. But due to a sudden surge in data, the classical computer system has been becoming weak in data processing. Quantum computers offer promising substantial speedup over classical computers for many applications. Quantum chip fabrication has made remarkable gains in recent years, with the number of qubits and fidelity growing. In general computing, a binary digit is the smallest unit of information or a bit. “In quantum computing, the term Qubit (Quantum Bit) serves the exact function of the term bit.” IBM Research released the IBMQ Experience in 2018, the first quantum computer that anyone can use and make accessible to a huge audience of different countries through cloud access. IBM also introduced the tool QISKIT (Quantum information software kit), which enables teachers, researchers, and developers to write coding and run their coding on quantum machines. It also includes different packages of quantum computing. In this paper, the author has discussed different steps to install qiskit. Mainly this paper focused on the “programming and application side of quantum computing.” Qiskit tools used in the python programming language. The “quantum circuits” are fabricated with the use of quantum gates and favorable algorithms with less execution time","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121250260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the purpose of the study, 228 sample households were selected from the town using a stratified random sampling technique and the field data were collected using questionnaires. The binary linear regression model analysis was employed to identify determinants that affect the dairy market. The model result showed that dairy market was strongly and significantly affected by use of improved feed, demand for milk, frequency of getting training, access for credit, and education of the household heads. Shortage of feed and seasonality of demand, particularly in fasting time are challenges of dairy marketing in the area. Dairy producers, retailers, farms, and cooperatives were found the main milk market channel of the study area. The dairy market in the study area uses an informal marketing system which shows the underdevelopment of dairy marketing. Thus, dairy development interventions should be aimed at addressing both dairy production technological gaps and marketing problems. Further, the study shows that there is a high demand for dairy products. Therefore, dairy processing industry’s establishment, support for dairy producers and improving access to services should receive due attention in order to improve dairy market in the study area by all dairy development stakeholders","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115661048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yitbarek, Isreal Zewide, Kibinesh Adimasu","doi":"10.58414/scientifictemper.2023.14.1.10","DOIUrl":"https://doi.org/10.58414/scientifictemper.2023.14.1.10","url":null,"abstract":"One of the main reasons for Ethiopia’s declining agricultural production is land use change under poor soil management practices. Hence, in order to evaluate the effects of various land use types on certain soil qualities, research was done on the soils of Cheha district, Gurage zone in Ethiopia’s central highlands. Four different land use types (LUTs) (cultivated, enset, eucalyptus, and wild forest) were used for this study to assess and analyze their response to soil fertility. A total of 48 soil samples (24 undisturbed and 24 disturbed) was collected from the selected LUTs and two different soil depths (SDs) (0-20 and 20-40 cm) with three replications for the laboratory analysis. The results showed that most of the properties of soil physicochemical properties of soil were significantly affected by LUTs, SD, and the interactions. The result showed that the highest sand (43%), silt (46.5%), and clay (30.30%) fractions were observed under forest land (FL), enset farmland (ENFL), and cultivated land (CUL), respectively. Concerning the SD, higher silt (40.9%) and clay (28.3%) were found in the subsurface soils. Except for CUL, textural classes of all LUTs were loamy. The highest (1.37 g cm-3) bulk density was observed under the subsurface soils of CUL and the lowest (1.06 g cm-3) was in the surface soils of FL and ENFL. In contrast to bulk density, total porosity was highest (60.1%) under surface soils of FL and ENFL and the lowest (48.3%) value was observed under subsurface soils of CUL. The combination of two factors influenced the soil pH. The highest value (6.54) and lowermost (4.82) values were found under the surface soils of ENFL and subsoils of EUCL, respectively. Comparatively, the uppermost (7.48%) and lowermost (3.55%) values of organic matter were recorded under the surface soils of FL and subsoils of EUCL. The uppermost (0.37%) and lowermost (0.17%) values of total nitrogen were registered under surface soil and subsoils of FL and EUCL, respectively. The uppermost (22.69 mg kg-1) value of Av.P was registered under superficial soils of ENFL and the lowermost (5.02 mg kg-1) was obtained under a subsurface layer of EUCL. The uppermost (37.96 cmol(+) kg-1) and lowermost (11.90 cmol(+) kg-1) of CEC values were observed under the surface soils of FL and subsoils of EUCL. The uppermost value of exchangeable acidity (1.85 cmol(+) kg-1) was recorded under soils of EUCL. This study showed that different LUTs and SDs have substantial impacts on the status of soil fertility. Soils of FL and ENFLs were relatively more fertile. Increasing eucalyptus tree cover on arable land and intensive farming severely impacted soil fertility which may have increased soil acidity. Appropriate land use and a variety of soil fertility management practices are crucial to address soil fertility loss and acidity issues","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130081676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both primary and secondary data were collected through questionnaires, interviews and document analysis. Collected data were analyzed both qualitatively and quantitatively. The study revealed that farmers are effectively applying agronomic, physiological, pre- and post-harvest activities and producing quality coffee. However, they are not getting economic benefits from their product. Due to this, they are not motivated to produce high amounts and quality of coffee on their farmland. Cooperatives are not effectively providing services for their members. The government is also playing a role in improving the performance of cooperatives.
