Assessment of Teachers’ Technological and Pedagogical Knowledge of Integrating ICT in teaching English in Secondary Schools in Nairobi County, Kenya

The purpose of this study was to assess teachers’ technological and pedagogical knowledge of integrating ICT in teaching English in secondary schools in Nairobi County, Kenya. The study was guided by two frameworks: Technological Pedagogical and Content Knowledge (TPACK), and Teacher Cognition. The study employed an explanatory sequential mixed-methods approach to collect both qualitative and quantitative data. The study adopted a descriptive survey research design, and pragmatic world view as a philosophical orientation. The sample consisted of 20 secondary school teachers of English from Nairobi County. Simple random and purposive sampling techniques were used. Data was collected using an interview schedule and a teacher questionnaire. Data were analysed using descriptive statistics: frequencies, percentages, means, standard deviations and presented in tables and short descriptions and content analysis procedures and presented in narrations based on thematic areas derived from the study variables. The findings revealed among other things that, 75% of the teachers of English sampled lacked TPACK to effectively integrate ICT in their teaching, the training required by teachers of English to integrate ICT in their teaching and the resources needed to deliver this were inadequate in many schools under study. The study concluded that: teachers of English needed sufficient technological pedagogical knowledge and adequate ICT skills to effectively integrate ICTs in their teaching, the aspirations of national educational authorities because of establishing ICT competencies does not automatically result in changes in classroom practices. The study recommended that teachers be provided with professional development as a continuous process on the integration of ICT in teaching; underscoring the importance of the continued teacher development in ICTs to enhance English language teaching. The study further challenges policymakers in the secondary school context to develop .
Performance comparison of OLSR, GRP and TORA using

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves, i.e., routing functionality will be incorporated into mobile nodes. In this paper routing protocols OLSR, GRP and TORA for mobile ad hoc network are compared on the basis of delay, load, media access delay and throughput.
Wheat Spikelet Length Response to Phosphate Fertilizers on Acid Soils in Uasin Gishu County, Kenya

The study aimed at investigating response of wheat spikelet length, grain yield, grains per spikelet, and soil chemical properties as influenced by liming at 2tha (main plots), P sources NPK (23:23:0), DAP (18:46:0), and SSP (0:20:0) (SSP)(sub-plots) and, P rates (sub sub-plots) P0; 0 kg P ha, P1; 8.8 kg Pha, P2; 17.6 kg Pha and P3; 26.4 kg Pha. A split-split plot arrangement laid out in a RCBD experiment was set up in two county sites; Chepkoilel and Kipsangui in 4 m plots, replicated 3 times. Data collected on spikelet length, grain per spikelet and grain yields were subjected to ANOVA using SAS 9.1 for Windows 2012 statistical package. Separation of means was done at 95% confidence level using Tukeys. Lime application significantly increased (p≤0.05) the spikelet length and grains/spikelet in both Chepkoilel and Kipsangui. Phosphorus rich fertilizer NPK application resulted in a significant (p≤0.001) increase in spikelet length and grains/spikelet in Chepkoilel and Kipsangui. NPK at 26.4 kg P/ha yielded a significantly high grains/spikelet (37.0k and 36.17g grains/spikelet) in Kipsangui and Chepkoilel respectively. The study recommends NPK (23:23:0) fertilizers at a rate of 26.4 kg P ha for Chepkoilel and Kipsangui plus lime at 2tha as most effective in improving spikelet length, grain per spikelet and grain yield.
Ultrasound–guided posterior quadratus lumborum block for postoperative pain control after minimally invasive radical prostatectomy: a randomized, double–blind, placebo–controlled trial

A minimally invasive approach to radical prostatectomy offers improved ambulation and discharge times. Postoperative pain control is one of the key factors that facilitates rapid recovery. With the aim to assure adequate analgesia and minimize the use of opioids, application of truncal nerve blocks has been proposed in a number of endoscopic procedures. The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of bilateral posterior quadratus lumborum block (pQLB) in alleviating pain and reducing postoperative opioid demand in patients following endoscopic extraperitoneal and laparoscopic prostatectomy. We enrolled 50 patients who were diagnosed with prostate cancer and scheduled for prostatectomy. They were randomized to receive preoperative, ultrasound-guided pQLB with the use of either 30 ml of 0.375 % ropivacaine (ropivacaine group) or 30 ml of 0.9 % NaCl (placebo group). Our primary endpoint was opioid consumption in the first 24 hours after surgery. Secondary endpoints were pain intensity at predefined timepoints and the incidence of nausea and vomiting and pruritus. No differences were detected between the ropivacaine and placebo groups in intravenous oxycodone consumption during the first 24 hours after surgery. Similarly, there were no differences in pain intensity at any of the timepoints assessed. The rate of nausea and vomiting was equal in both groups and pruritus was not observed. Application of bilateral pQLB does not reduce opioid consumption after minimally invasive prostatectomy.
Special Issue on Responsible AI and Human-AI Interaction

The design of artificial intelligent (AI) enhanced adaptive assistive technologies (AATs) presents exciting promise for those with motor or audio/vision impairment. However, these technologies also introduce tremendous privacy risks, particularly for those with compounding identity vulnerabilities. In this paper, we reflect on why and how AATs need to be designed in collaboration with intersectional AAT users to ensure that the benefits of AI do not sacrifice privacy for the most vulnerable. We discuss methods and tools we have developed to meet these challenges, lessons we have learned from studies with them, and future opportunities.
Microstructural and Chemical Investigations of Presolar Silicates from Diverse Stellar Environments

We report the structural and chemical investigation of nine presolar silicate grains from the CH3/CBb3 chondrite Isheyevo and CR2 chondrite Northwest Africa (NWA) 801. Five of these grains belong to group 1, likely condensed in low- to intermediate-mass asymptotic giant branch (AGB) stars, super-AGB stars, or core-collapse supernovae, while the remaining four grains belong to group 4 and have a supernova origin. The advanced transmission electron microscopy and associated electron spectroscopy analyses show a diverse range of chemical and structural compositions for presolar silicates. Two GEMS (glass with embedded metal and sulfide)-like silicates, each from different groups, condensed under nonequilibrium conditions in stellar outflows. Two nonstoichiometric silicates from group 1 have dissimilar formation and alteration histories. An amorphous silicate from group 1 with olivine-like [(Mg,Fe)2SiO4] composition likely formed as a crystalline olivine that subsequently amorphized in the interstellar medium. An oldhamite (CaS) grain within a stoichiometric enstatite (MgSiO3) from group 1 probably formed by heterogeneous condensation in circumstellar outflows. Of the two crystalline grains from group 4, one is an antigorite [(Mg,Fe)3Si2O5(OH)4], while the other is a nontronite [Na,Fe2(Si,Al)4O10(OH)2.nH2O], both formed as a crystalline forsterite and later altered to have hydrated silicate composition. A group-4 silicate has a chemical composition similar to a low Ca-pyroxene [(Ca,Mg)(Si,Al)2O6]. Our data imply that presolar grains from different groups can have a similar range of grain-formation conditions.
Double-atom catalysts for energy-related electrocatalysis applications: a theoretical perspective

Due to the excellent activity, selectivity, and stability, atomically dispersed metal catalysts with well-defined structures have attracted intensive research attention. As the extension of single-atom catalyst, double-atom catalyst (DAC) featuring with the metal dimer anchored on a suitable substrate has recently emerged as a research focus for the energy-related electrocatalysis reactions. Due to the flexible dual-metal sites and the synergetic effect between the two metal atoms in DACs, there are more possibilities to adjust their geometrical configurations and electronic structures. The wide tunability of the active sites could offer more opportunities to optimize the binding strength of the reaction intermediates and thus the catalytic activity and/or selectivity of chemical reactions. Moreover, the neighboring metal sites provide a platform to perform more complex electrocatalysis reaction involving the chemical bond coupling. This review aims to summarize the recent advance in theoretical research on DACs for diverse energy-related electrocatalytic reactions. It starts with a brief introduction to DACs. Then an overview of the main experimental synthesis strategies of DACs is provided. Emphatically, the catalytic performance together with the underlying mechanism of the different electrocatalytic reactions, including nitrogen reduction reaction, carbon dioxide reduction reaction, oxygen reduction reaction, and oxygen and hydrogen evolution reactions, are highlighted by discussing how the outstanding attributes mentioned above affect the reaction pathway, catalytic activity, and product selectivity. Finally, the opportunities and challenges for the development of DACs are prospected to shed fresh light on the rational design of more efficient catalysts at the atomic scale in the future.

An integrated assessment of the effect of environmental regulation, land use changes and market forces on the Mexican leather and footwear industries’ restructuring

Traditional theories of industrial restructuring assign the most explanatory weight of the structural change phenomenon to increasing pressures via globalization and falling trade barriers. This thesis offers a new model of thinking about industrial restructuring that includes multiple stressors. The thesis focuses on three main drivers of structural change: market pressures, environmental regulation and changes in land use and land pricing, using two case studies of leather and footwear industrial clusters in Mexico, located in the cities of León and Guadalajara. Evidence of multiple drivers of structural change is found in the dissertation. Furthermore, responses to restructuring drivers in León and Guadalajara are found to be substantially different. Firms in the leather and footwear cluster in León have implemented countervailing strategies such as price competition, government lobbying, and more recently, investment in socio-economic research (competitiveness) projects. However, firms in the leather and footwear cluster in Guadalajara focused on a specific, high-end target market. At the larger, urban scale, footwear and its allied industries in the city of León resisted change and have tried to remain in operation while the city of Guadalajara has focused on a diversification strategy, attracting new (arguably more technically advanced) industries. This thesis offers empirical and theoretical advances. Empirically, it applies a firm demographics approach to the study of industrial clusters under multiple stressors. This approach has not been previously used on Mexican data. Theoretically, it demonstrates that future analyses of industrial complexes’ structural change can be strengthened through the use of an integrated assessment framework investigating the effect of multiple stressors (market forces, land pricing, technical change, environmental regulations, and consumer preferences) on industrial restructuring.
Dv/Dt-Control Methods for the SiC JFET/Si

Switching devices based on SiC offer outstanding per- formance with respect to operating frequency, junction tempera- ture, and conduction losses enabling significant improvement of the performance of converter systems. There, the cascode consist- ing of a MOSFET and a JFET has additionally the advantage of being a normally off device and offering a simple control via the gate of the MOSFET. Without dv/dt-control, however, the tran- sients for hard commutation reach values of up to 45kV/μs, which could lead to electromagnetic interference problems. Especially in drive systems, problems could occur, which are related to earth currents (bearing currents) due to parasitic capacitances. There- fore, new dv/dt-control methods for the SiC JFET/Si MOSFET cascode as well as measurement results are presented in this pa- per. Based on this new concepts, the outstanding performance of the SiC devices can be fully utilized without impairing electromagnetic compatibility.
Determination of Pelvic Limb Alignment in Small-breed Dogs

The present study determined the normal reference ranges for overall pelvic limb alignment of small-breed dogs. For this purpose, 60 cadaveric canine pelvic limbs from normal small-breed dogs (Maltese, Poodle, Shih Tzu, Yorkshire Terrier). A frontal full-limb radiograph of each pelvic limb was obtained, and mechanical tibiofemoral angle (mTFA), mechanical metatarsotibial angle (mMTTA), mechanical axis-femur angle (MAFA), and mechanical axismetatarsus angle (MAMTA) were measured from each radiograph, along with mechanical deviation of the stifle (SMAD) and tarsal joints (TMAD). The 95% CI for radiographic values of all pelvic limbs were mTFA, 5.7-7.4; mMTTA, −2.2 - −0.8°; MAFA, 3.5-4.5°; MAMTA, 1.0-2.0; SMAD, 2.1-2.7%; TMAD, 0.5-1.0%. There values varied among the breeds, except for mTFA. The reference ranges can be used for diagnosing pelvic limb deformities in small-breed dogs and for planning corrective osteotomies.
ANALYSIS OF FACTORS CAUSING JABODETABEK COMMUTER

Available online: 26 November 2021 The goal to be achieved through this research is to identify the factors that cause delays in the commuter train journey across Bogor-Manggarai Jakarta. The research question is why there is a delay in the journey of the Jakarta Bogor, Depok, Tangerang, Bekasi Commuter Train crossing Bogor-Manggarai. This study uses the Analytic Hierarchy Process to analyze timeliness. With the number of informants taken as many as 12 informants consisting of five people from regulators, five people from operators, one expert in the field of railways and users of commuter train of Jakarta Bogor, Depok, Tangerang, Bekasi. From the measurement results, it was found that the Jakarta, Bogor, Depok, Tangerang, Bekasi Commuter train was still experiencing delays, due to follow-ups and cross-changes in the operation pattern of the Jakarta Bogor, Depok, Tangerang, Bekasi Commuter Train which was still mixed with long-distance and freight trains, the construction of the Manggarai station as part of the Double Double Track project, the signaling system at the station. Manggarai also underwent changes and there were speed restrictions at Manggarai Station. Recommendations are to complete the construction of the Manggarai and Jatinegara stations which are useful for separating inter-city and urban rail travel, updating the signaling system on the crossing between Bogor Station-Manggarai Station and City Station which is now 30 years old, handling and improving level crossings with coordinate with related units.
Early reduction of corneal sensitivity in HZO

24 Purpose: To identify clinical factors associated with the early reduction of corneal sensitivity (CS) in 25 patients with herpes zoster ophthalmicus (HZO). 26 Methods: Total 30 subjects were divided into two groups according to the occurrence of an early 27 reduction of CS (Group 1: normal CS; Group 2: decreased CS). The demographics, ocular 28 manifestations of HZO, and the ocular surface parameters were compared between two groups. Then, 29 the relative risks of variables were analyzed to expect the early decrease of CS by HZO using logistic 30 regression analysis. 31 Results: Among total 30 subjects, the CS decreased in 10 subjects (3.2±1.4 cm, Group 2) and the 32 other 20 subjects revealed normal CS (6.0±0.0 cm, Group 1). The age was higher in the group 2 33 (67.0±16.6 years) than in group 1 (48.0±17.6 years, P=0.013), but sex and the comorbidity of 34 diabetes mellitus was not difference between groups. The presence of corneal punctate epithelial 35 erosions was a single factor among the ocular manifestations of HZO, which discriminated group 1 36 (5%) and group 2 (60%, P=0.002). The ocular surface staining scores (i.e. NEI scores and SICCA 37 OSS) were higher in group 2 (P=0.001 and P=0.021, respectively) than in group 1. The existence of 38 corneal punctate epithelial erosions revealed as a sole risk factor for the early reduction of CS (odds 39 ratio=33.085, P=0.016). 40 Conclusions: It is necessary to pay attention to the possible occurrence of neurotrophic keratopathy 41 especially in older patients with HZO showing an initial presence of corneal punctate epithelial 42 erosions. 43 44
The Design, Development and Evaluation of 3D Aerofoils for High Speed Axial Compressors: Part 2 — Simulation and Comparison With Experiment

The focus of this paper is to report on measurements from and simulation of Cranfield University’s 3-stage high-speed axial compressor test rig. This newly built rig is supported by European Commission funding and has tested a set of conventionally stacked 2D rotor and stator blades (Reference 1). The results were used to evaluate and to assess the performance of several commercially available CFD codes leading to the collaborative design of an advanced three-dimensional blade set. The philosophy behind the advanced design is described. The datum test results show that the state of the art, highly loaded, datum compressor is well matched with limited potential for loss reduction. A comparison is made between the measured results and a series of numerical analyses using the various CFD codes. Although the codes showed reasonable qualitative agreement with each other and the measured data, there were significant differences in the predicted performance of the datum build. Further the codes were unable to grade candidate redesigns consistently on a quantitative basis and therefore increased the difficulty of selecting suitable ‘3d’ features. Generic studies involving sweep, lean and recambering are used to evolve a design philosophy for the advanced three-dimensional design. Over cambering of the end-wall sections, coupled with a suitable stack of the blades, enables the blade count to be reduced. In the presence of a clearance combinations of sweep and lean are used to modify the loading in the clearance gap, thereby influencing the associated losses. The application of three-dimensional features redistributes the flow. The opportunity is therefore taken to rematch the sections based on the predicted results of the CFD codes. The above philosophy is used in the redesign of the datum compressor. Overall characteristics and exit traverse results from the test of the advanced build are compared to those from the datum build.Copyright © 2005 by ASME
Indikation einer präoperativen antibiotischen Prophylaxe bei Insertion enossaler Implantate – ein Systematisches Review

Ziel dieser Studie ist es, mit einem Überblick über die vorhandene Literatur eine Antwort auf die folgende Frage zu finden: Reduziert eine präoperative antibiotische Prophylaxe bei Patienten, die keiner medizinischen Risikogruppe angehören, vor zahnärztlicher Implantation die Anzahl der Implantatfrühverluste? Potentiell relevante Literaturstellen wurden mit Hilfe einer systematischen Literatursuche in den elektronischen Datenbanken Pubmed, Medpilot und der Cochrane Library und durch eine ergänzende Handsuche in zahnmedizinischen Zeitschriften identifiziert. Es fand eine systematische Bewertung der Studienqualität und eine Metaanalyse statt. Acht Studien entsprachen den Einschlusskriterien: In beiden randomisierten und verblindeten Studie der Evidenzstufe I konnte jeweils kein signifikanter Unterschied zwischen der Interventionsund Kontrollgruppe bezüglich der Implantatverlustrate nachgewiesen werden. Die Studien der Evidenzstufe II zeigten ebenfalls nur eine leichte Reduktion der Frühverlustrate bei Anwendung einer präoperativen Antibiose. Wir führten eine Aggregation der Daten der prospektiven klinischen Studien mit Kontrollgruppen durch, welche natürlich mit entsprechender Vorsicht interpretiert werden muss, da die Heterogenität zwischen den vier Studien ausgeprägt ist. Hier zeigt sich ein statistisch signifikanter Unterschied zwischen der Verlustrate der Interventionsgruppe und der der Kontrollgruppe. Durch eine präoperative Antibiose ließ sich dabei die Implantatverlustrate leicht senken (Number Needed To Treat 56). Basierend auf der vorliegenden Evidenz „mittlerer Qualität“, lässt sich eine „schwache“ Empfehlung für eine Antibiotikaprophylaxe bei Implantatinsertion mit einem Penicillin aussprechen.
