Authors: Kaaria Stephen Kinoti , Njuguna Reuben 
Published: July 2019

ERP technology has been embraced as an enterprise-wide package to integrate all necessary business functions into a single system with a shared database. It enhances decision making in business process and systemically harmonizes the activities of sales and marketing, manufacturing processes, operational management, product and service logistics, product purchasing, financial management, product development, and management of human resources. The study examined organizational attributes influencing implementation of enterprise resource planning in a medical research institute in Kenya. The study sought to explore the influence of top management support, implementation team, user support and resource availability on ERP implementation at KEMRI-Wellcome Trust research programme. The study used descriptive survey as research design. The target population was employees of KEMRI Wellcome Trust and Technobrain Kenya, the consulting firm. Data collection methods used were questionnaires. A preliminary study was carried out to test the rationality and reliability of the questionnaire. Considering the study was be descriptive in nature, data was analysed using descriptive statistics like frequencies and tables. Linear regression model was also used to validate if the relationship between the independent variables and the dependent variable is statistically important. The regression indicated that ERP implementation (the dependent variable) was highly influenced by top managements support, implementation team, user support and resource availability (the independent variable). Conclusively, the findings suggested that user support, resource availability, and top management had a central role in implementing effective ERP plans.

Authors: Chepkwony Hillary Kipkoech , Njoroge Jane 
Published: July 2019

The main objective of this study was to examine the effects of Performance Appraisal Practices on employees’ performance in public secondary schools in Kenya. Performance appraisal practices are the independent variable and Employees’ performance is the dependent variable. Since 2012, the Teachers Service Commission (TSC) has been appraising teachers across the country using a system of appraisal whose effectiveness has not been fully tested. Past research findings have depicted the current performance’ appraisal practices in Kenyan Secondary School’s to exhibit weaknesses, which need to be urgently addressed if it is to improve employees’ performance in Kenya. With these findings, this research sought to analyse the current state of employees’ appraisal practices in Kenya’s Public Secondary Schools. This study examined the key issues related to teacher appraisal in public secondary schools with special reference to Embakasi Sub-county in Nairobi city County, Kenya. The research was anchored on Hardner performance standards theory and the Resource based view theory. The target population consisted of the teachers employed by the Teachers Service Commission and working within Embakasi sub- County. The research adopted census technique in data collection hence there was no sampling of respondents. The study involved 119 respondents for the study which included; 105 teachers and 7 principals and 7 Deputy Principals. Data collection in this study was done using a structured questionnaire. The instrument reliability was tested using Cronbach’s alpha coefficient of 0.5 philosophy. Descriptive and inferential statistics were undertaken using SPSS V.22 and the results were used to derive conclusions and make inferences. ANOVA analysis model was fitted to explain the relationship between the independent and the dependent variables. The study recommended that other teacher preparation, the school authorities should ensure conformity with Ministry of Education guidelines on adequate classroom physical space; there should be a regular appraisal of teachers’ responsibility by school authorities as a standard measure of their preparedness prior to service delivery and finally create a conducive environment that enhances teachers’ creativity and innovation.

Authors: Njoroge Allan Njuguna , Bett Shadrack 
Published: July 2019

Small and Medium Enterprises (SMEs) in Kenya have not performed creditably well and hence have not played the expected vital and vibrant role in the economic growth and development of Kenyan economy. This situation has been of great concern to the government, citizenry, operators, practitioners and the organized private sector groups especially because many of the SMEs owners are faced with unpredictable operating environment which presents many entrepreneurs with a challenge of both growing and managing their SMEs consequently affecting SMEs performance. The study aimed at establishing operating environment effects on performance of small and micro enterprises in urban townships in West Pokot County. The specific objectives of the study included determining the influence of skills and competence, technology, legislations and competition on the performance of small and micro enterprises in urban townships in West Pokot County. The study was anchored on the theory of multi-dimensional performance, goal setting theory and Human capital theory. The target population was drawn from small and micro enterprises owners and managers in the two major townships in West Pokot County that is Kapenguria, and Chepareria Townships. The study was based on descriptive research design where the researcher used stratified random sampling techniques to sample its respondents; Questionnaires were used for the data collection. Both descriptive and inferential statistics were undertaken. Inferential statistics was used to test the extent and nature of the relationship between dependent and independent variables. The correlation results of the study found that SMEs owners/managers skills and competence, technology and competition are positively related to SMEs performance. Results further showed that legislations are negatively related to SMEs performance.SMEs owners/managers skills and competence, legislation, technology and competition were found to be significant variables in explaining SMEs performance which is illustrated by coefficient of determination(R square) of 79.4%.Based on the research findings the study concluded that SMEs owners/managers skills and competence, legislation, technology and competition has a significant relationship with SMEs performance. The study recommends that the financial institutions, NGOs, and Government agencies should work in collaboration in improving SMEs owner’s skills and competence, also technological changes awareness should be provided to the SMEs owners and managers. The Government agencies should come up with friendly policies and regulations to eliminate unhealthy competition towards the SMEs.

Abstract
Among more than 200 quasars known at z ≳ 6, only one object, J0100+2802 (z = 6.327), was found hosting a >1010
M
⊙ supermassive black hole. In order to investigate the host galaxy properties of J0100+2802, we performed multi-band ALMA observations, aiming at mapping the dust continuum, [C ii] and CO(6–5) emission lines with subkiloparsec scale resolution, as well as detecting high-J CO lines in CO(11–10), CO(10–9), and CO(7–6). The galaxy size is measured to be R
major = 3.6 ± 0.2 kpc from the high-resolution continuum observations. No ordered motion on kiloparsec scales was found in either the [C ii] or the CO(6–5) emission. The velocity dispersion is measured to be 161 ± 7 km s−1, which is about three times smaller than that estimated from the local M–σ relation. In addition, we found that the CO emission is more concentrated (a factor of 1.8 ± 0.4) than the [C ii] emission. Together with CO(2–1) detected by the Very Large Array (VLA), we measured the CO spectral line energy distribution, which is best fit by a two-component model that includes a cool component at ∼24 K with a density of

cm−3, and a warm component at ∼224 K with a density of

cm−3. We also fit the dust continuum with a graybody model. This indicated that the continuum has either a high dust emissivity β ≳ 2 or a hot dust temperature T
dust ≳ 60 K, or a combination of these two factors. The highly excited CO emission and hot dust temperature suggest that the powerful active galactic nucleus in J0100+2802 could contribute to the gas and dust heating, but future observations are needed to confirm this.
Thermal Conduction Effects on the Accretion–Ejection Mechanism. I. Accretion Flow Investigation

Published: July 2019

Abstract
Understanding the accretion of matter around compact objects such as young stars or black holes remains one of the most interesting problems in astrophysics. Recent observations detected the accretion of matter of several young stars from their circumstellar disk and proposed the existence of the X-ray emission at very high temperature. The hot gases surrounding these systems are likely to proceed under the collisionless regime, which indicates that the thermal conduction has a relevant contribution in the transport of energy along the accretion disks. Notwithstanding its importance, this physical ingredient is largely neglected in previous time-dependent studies of accretion–ejection structure. More research is still necessary before obtaining a complete picture of such a phenomenon. In this series, we have included the three nonideal effects together, viscosity, resistivity, and thermal conduction, to explore the physical mechanism of the disk–jet system. We carry out extensive time-dependent simulations of the accretion disk and jet using the PLUTO code. The mean field approach is used in this work by taking into account the evolution of the disk and jet simultaneously. We show in this first paper how the thermal conduction plays a crucial role in the accretion disk dynamics by presenting a detailed discussion of its effects on the evolution of basic facets of the inflow properties with a special emphasis on the equatorial plane and disk surface. Our model also shows strong indications of the ejection efficiency improvement in the presence of thermal conduction.
Regional Approach to Biodiversity Information Management and Reporting in Southeast Europe
Authors: Velagić-Hajrudinović Azra 
Published: July 2019

Featuring a large variety of ecosystems, abundant freshwater and forest resources, unique extensive karstic systems, and a high level of biodiversity and endemism, Southeast Europe (SEE) plays a crucial role in the conservation of biodiversity in Europe and beyond. In order to conserve and sustainably use these biodiversity assets and valuable natural resources, a regional concerted approach in the field of biodiversity information management and reporting (BIMR) has been strengthened. This has enabled improvement in access, transparency and exchange of biodiversity data and reporting processes among the participating economies.
Certain significant and visible progress among SEE economies and stakeholders is due to to the knowledge gained about regional and national BIMR baselines, agreed and elaborated minimum Convention on Biological Diversity (CBD) and European Union (EU) requirements on BIMR among stakeholders and implemented BIMR tools (e.g., a regionally unified fundamental database for the Information System for Nature Conservation (ISNC), for instance in Montenegro (http://zasticenapodrucja-cg.tk//en), Bosnia and Herzegovina/entity of Republika Srpska (http://e-priroda.rs.ba/en/) and entity of Federation of Bosnia and Herzegovina and North Macedonia (Standard Data Form - SDF application for NATURA 2000) and compiled dataset on five taxonomic groups of endemic taxa using the Darwin Core standard). Therefore, BIMR activities/priorities from the region have become more evident and supported along with ownership of BIMR tools acquired by the partner institutions and recognized at the global level through the Global Biodiversity Information Facility (GBIF).

Platelet-rich plasma (PRP) is blood plasma containing an above baseline level of platelets and growth factors. PRP is an emerging new treatment utilized to enhance wound healing and has been in clinical use over the last several decades within many disciplines, such as orthopedic, oral-maxillofacial and cardiac surgery. Recently, PRP has come to the attention of esthetic surgeons, with burgeoning new applications ranging from hair restoration to soft tissue augmentation. The goal of this review is to describe the current body of literature on PRP as it pertains to the field of esthetics, and to review its current real-world applications. PRP's utility in cosmetic surgery is rapidly growing and offers a promising and exciting new therapeutic modality.
Management of the Internal Nasal Valve
Authors: Li Shia Ng , Stephen Lo 
Published: July 2019

ABSTRACTNasal obstruction is one of the most common nose complaints. Internal nasal valve dysfunction is an important cause of nasal obstruction, particularly in patients who have a previous history of nasal trauma or reduction rhinoplasty. Correct assessment is crucial for accurate diagnosis and appropriate management planning. Various surgical and nonsurgical modalities for addressing the problem of internal nasal valve collapse are being reviewed in this paper. Each technique have their own advantages and disadvantage, and the choice depends on the underlying pathology, patient preference, availability of graft material. The rhinoplasty surgeon should have a thorough understanding of the available options as part of his/her armamentarium in dealing with internal nasal valve pathology.

Authors: Verma Hitesh 
Published: July 2019

ABSTRACTCavernous hemangiomas are relatively rare vascular malformations especially in an adult. The childhood hemangioma generally regresses spontaneously. We present the case report of a 52-year-old male patient, who had a hemangioma from the childhood and it had grown to such a large size so as to cause extreme cosmetic deformity for the patient. The long standing duration of almost 45 years and the extremely large size of the hemangioma make it a very rare case.

In fact, metastatic malignant melanoma and squamous cell carcinoma are the two most common causes of death in XP victims.This series represent rare presentations of malignancies in non-sun-exposed areas in such patients.
Surgical Incisions: Balancing Surgical and Cosmetic Outcomes in Head and Neck Oncosurgery
Authors: Tubachi Jagadish , Jainkeri Vivek , Gadagi Vinay , Gunari Prasad 
Published: July 2019

ABSTRACTThe oral and oropharyngeal cancer surgery is challenging due to presence of carotid arteries, internal jugular vein and cranial nerves in close proximity to the primary tumor or matastatic lymph node. So surgical incisions should be planned to improve oncologic resection without compromising functional and esthetic outcomes. Macfee and Crile's incision are commonly used in present day oncologic practice. Extension and probable modification of these incisions depending on case scenerio are discussed.
Pleomorphic Adenoma of the Nasal Septum
Authors: Tejendrasingh Thakur Rahul , Laxmanrao Sonawale Sanjay Kumar 
Published: July 2019

ABSTRACTPleomorphic adenoma is a common, benign tumor arising from the major salivary glands, most commonly from the parotid gland. In addition, they may also occur in the minor salivary glands of the hard and soft palate. Intranasal pleomorphic adenomas are unusual and may be misdiagnosed because they have greater myoepithelial cellularity and fewer myxoid stromata compared to those elsewhere. We report a case of pleomorphic adenoma of the nasal cavity arising from the nasal septum.

Authors: Klinge Kathleen , Mueller Andreas 
Published: July 2019

ABSTRACTBackgroundUsing neck ultrasound to evaluate the status of the lymph nodes of a patient with a head and neck cancer is common practice but laryngeal ultrasound could help to receive more information of the tumor.Methods and resultsWe report a case of an initially T1a N0 M0 G2 R0 squamous-cell carcinoma of the right vocal cord. Despite regular follow-up, the relapse of the tumor remained undetected. The hypopharyngoscopy and laryngoscopy were performed. The tumor was evaluated with laryngeal ultrasound and to confirm the relapse of the tumor a MRI scan was performed. Endoscopically there was no obvious presence of the tumor. Laryngeal ultrasound facilitated the visualization of the tumor in good quality.Unfortunately, a total laryngectomy was necessary to treat the relapse of the squamous-cell carcinoma (T4a N0 (0/16) M0 G2 R0).ConclusionDespite careful follow-up via laryngoscopy a relapse of the laryngeal tumor was not visible. Using laryngeal ultrasound, the relapse might have been detected sooner.

Published: July 2019

ABSTRACTAlthough they are relatively rare, osteomas are the most frequent benign neoplasm of the paranasal sinuses. When they are large or symptomatic, surgical intervention through open or endoscopic approaches is required. The association between osteoma and myxoma is rarely addressed in the literature and myxoid degeneration of osteomas is not known. We report a case of a giant frontoethmoidal osseous lesion in a 52 years old man which was completely removed through an open approach. Histological examination of the removed mass revealed an osteoma with a myxoid component.

The most common tumor associated with the disease is the vestibulocochlear schwannoma, and as many as 10% of patients with this tumor have neurofibromatosis type 2. In this report, we aim to present a 36-year-old female who presented with chief complaints of unilateral tinnitus, and, during her workup, which included cranial and whole spine magnetic resonance imaging, we found bilateral acoustic neuroma with multiple meningiomas. Based on clinical and imaging findings, the diagnosis of neurofibromatosis type 2 was made.
Effects of Radiotherapy on Auditory and Vestibular Function
Authors: Nilakhe Sachin Sharad 
Published: July 2019

ABSTRACTIntroductionRadiotherapy either primary or adjuvant, is a commonly used modality of treatment in head and neck malignancies. The audiovestibular apparatus is often within the fields of radiation treatment, and hearing loss is a possible complication. This study was undertaken to assess the audiovestibular functions in patients undergoing radiation therapy for head and neck malignancies to determine the type and severity of hearing loss and vestibular dysfunction following radiation therapy.Materials and methodsFifty patients with head and neck malignancies reported to the malignant disease treatment center of INHS Asvini and received radiotherapy as a primary modality of treatment or in combination with surgery during the period May 2003 to Sep 2004 were included in this study. None of these patients had prior treatment by chemotherapy.ConclusionA significant number of patients who were subjected to radiation therapy for head and neck malignancies develop conductive hearing loss is predominant in the immediate postradiation period. Conductive hearing loss is reversible and improves with the conservative line of treatment. Sensorineural hearing loss more commonly affects the higher frequencies and is more common in older patients. Sensorineural hearing loss is more common when radiation doses exceed 60 Gy. There is no conclusive evidence of vestibular dysfunction in patients undergoing radiotherapy for head and neck cancers.
