Abstract:

Renal ischemia induces peritubular capillary rarefication and fibrosis, with the latter partly resulting from the endothelial-to-mesenchymal transition (EndoMT). Endothelial cilia transmit blood flow-associated forces into the cell. Early endothelial progenitor cells (eEPCs) have been shown to protect mice from acute kidney injury in the short term. The aim of the present study was to analyze midterm consequences of eEPC treatment in the context of endothelial cilia and the EndoMT. Male C57/Bl6N mice were subjected to unilateral renal ischemia postuninephrectomy. Syngeneic murine eEPCs were systemically injected at the time of reperfusion. Animals were investigated 1, 4, and 6 wk later. Cultured mature endothelial cells were exposed to a variable flow with versus without eEPC supernatant incubation. Systemically injected eEPCs reduced serum creatinine levels at week 1 (35 and 45 min) and week 4 (45 min). Interstitial fibrosis was significantly diminished by cell treatment at all time points as well. The EndoMT was less pronounced at week 4 (35 min) and week 6 (45 min). eEPC supernatant reduced α-smooth muscle actin expression and α-tubulin abundance in flow-treated cultured mature endothelial cells, and percentages of cilium-positive cells increased. The loss of peritubular capillaries was prevented by eEPCs. Intrarenal endothelial α-tubulin decreased postischemia and was further reduced by eEPC administration. We conclude that eEPCs are capable of reorganizing the endothelial cytoskeleton in an indirect manner, ultimately resulting in stabilization of the endothelial ciliome. The investigation indicates an antimesenchymal role of endothelial cilia in the process of postischemic tissue fibrosis/EndoMT.

Abstract:

Endothelial progenitor cells (EPCs) protect the kidney from acute ischemic injury. The aim of this study was to analyze whether pretreatment of murine “early outgrowth” EPCs (eEPCs) with the hormone melatonin increases the cells' renoprotective effects in the setting of murine acute ischemic renal failure. Male (8–12 wk old) C57Bl/6N mice were subjected to unilateral ischemia-reperfusion injury postuninephrectomy (40 min). Postischemic animals were injected with either 0.5×106 untreated syngeneic murine eEPCs or with cells, pretreated with melatonin for 1 h. Injections were performed shortly after reperfusion of the kidney. While animals injected with untreated cells developed acute renal failure, eEPC pretreatment with melatonin dramatically improved renoprotective actions of the cells. These effects were completely reversed after cell pretreatment with melatonin and the MT-1/-2 antagonist luzindole. In vitro analysis revealed that melatonin reduced the amount of tumor growth factor-β-induced eEPC apoptosis/necrosis. Secretion of vascular endothelial growth factor by the cells was markedly stimulated by the hormone. In addition, migratory activity of eEPCs was enhanced by melatonin and supernatant from melatonin-treated eEPCs stimulated migration of cultured mature endothelial cells. In summary, melatonin was identified as a new agonist of eEPCs in acute ischemic kidney injury.

Abstract:

Endothelial progenitor cells (EPCs) are mobilized into the vascular space and home to damaged tissues, where they promote repair in part through a process of angiogenesis. Neuregulins (NRGs) are ligands in the epidermal growth factor family that signal through type I receptor tyrosine kinases in the erbB family (erbB2, erbB3, and erbB4) and regulate endothelial cell biology, promoting angiogenesis. Stimuli such as ischemia and exercise that promote EPC mobilization also induce cleavage and release of transmembrane NRG from cardiac microvascular endothelial cells (CMECs). We hypothesized that NRG/erbB signaling may regulate EPC biology. Using an embryonic (e)EPC cell line that homes to and repairs injured myocardium, we were able to detect erbB2 and erbB3 transcripts. Identical receptor expression was found in EPCs isolated from rat bone marrow and human whole blood. NRG treatment of eEPCs induces phosphorylation of kinases including Akt, GSK-3β, and Erk1/2 and the nuclear accumulation and transcriptional activation of β-catenin. NRG does not induce eEPC proliferation or migration but does protect eEPCs against serum deprivation-induced apoptosis. These results suggest a role for tissue-derived NRG in the regulation of EPC survival.

Abstract:

Tissue neovascularization involves recruitment of circulating endothelial progenitor cells that originate in the bone marrow. Here, we show that a class of embryonic endothelial progenitor cells (Tie-2+, c-Kit+, Sca-1+, and Flk-1−/low), which were isolated at E7.5 of mouse development at the onset of vasculogenesis, retain their ability to contribute to tumor angiogenesis in the adult. Using intravital fluorescence videomicroscopy, we further defined the multistep process of embryonic endothelial progenitor cell (eEPC) homing and incorporation. Circulating eEPCs are specifically arrested in “hot spots” within the tumor microvasculature, extravasate into the interstitium, form multicellular clusters, and incorporate into functional vascular networks. Expression analysis and in vivo blocking experiments provide evidence that the initial cell arrest of eEPC homing is mediated by E- and P-selectin and P-selectin glycoprotein ligand 1. This paper provides the first in vivo insights into the mechanisms of endothelial progenitor cell recruitment and, thus, indicates novel ways to interfere with pathological neovascularization.

Abstract:

Purpose – The purpose of this paper is to specify the decomposition conditions of Wand and Weber for the Business Process Model and Notation (BPMN). Therefore, an interpretation of the conditions for BPMN is derived and compared to a specification of the conditions for enhanced Event-Driven Process Chains (eEPCs). Based on these results, guidelines for a conformance check of BPMN and eEPC models with the decomposition conditions are shown. Further, guidelines for decomposition are formulated for BPMN models. The usability of the decomposition guidelines is tested with modelling experts. Design/methodology/approach – An approach building on a representational mapping is used for specifying the decomposition conditions. Therefore, ontological constructs of the Bunge-Wand-Weber ontology are mapped to corresponding modelling constructs and an interpretation of the decomposition conditions for BPMN is derived. Guidelines for a conformance check are then defined. Based on these results, decomposition guidelines are formulated. Their usability is tested in interviews. Findings – The research shows that the decomposition conditions stemming from the information systems discipline can be transferred to business process modelling. However, the interpretation of the decomposition conditions depends on specific characteristics of a modelling language. Based on a thorough specification of the conditions, it is possible to derive guidelines for a conformance check of process models with the conditions. In addition, guidelines for decomposition are developed and tested. In the study, these are perceived as understandable and helpful by experts. Research limitations/implications – Research approaches based on representational mappings are subjected to subjectivity. However, by having three researchers performing the approach independently, subjectivity can be mitigated. Further, only ten experts participated in the usability test, which is therefore to be considered as a first step in a more comprising evaluation. Practical implications – This paper provides the process modeller with guidelines enabling a conformance check of BPMN and eEPC process models with the decomposition conditions. Further, guidelines for decomposing BPMN models are introduced. Originality/value – This paper is the first to specify Wand and Weber's decomposition conditions for process modelling with BPMN. A comparison to eEPCs shows, that the ontological expressiveness influences the interpretation of the conditions. Further, guidelines for decomposing BPMN models as well as for checking their adherence to the decomposition conditions are presented.

Abstract:

Background: Streptozotocin (STZ) has served as an agent to generate an Alzheimer's disease (AD) model in rats, while edaravone (EDA), a novel free radical scavenger, has recently emerged as an effective treatment for use in vivo and vitro AD models. However, to date, these beneficial effects of EDA have only been clearly demonstrated within STZ-induced animal models of AD and in cell models of AD. A better understanding of the mechanisms of EDA may provide the opportunity for their clinical application in the treatment of AD. Therefore, the purpose of this study was to investigate the underlying mechanisms of STZ and EDA as assessed upon electrophysiological alterations in CA1 pyramidal neurons of rat hippocampal slices. Methods: Through measures of evoked excitatory postsynaptic currents (eEPSCs), AMPAR-mediated eEPSCs (eEPSCsAMPA), evoked inhibitory postsynaptic currents (eIPSCs), evoked excitatory postsynaptic current paired pulse ratio (eEPSC PPR) and evoked inhibitory postsynaptic current paired pulse ratio (eIPSC PPR), it was possible to investigate mechanisms as related to the neurotoxicity of STZ and reductions in these effects by EDA. Results: Our results showed that STZ (1000 µM) significantly inhibited peak amplitudes of eEPSCs, eEPSCsAMPA and eIPSCs, while EDA (1000 µM) attenuated these STZ-induced changes at holding potentials ranging from -60mV to +40 mV for EPSCs and -60mV to +20 mV for IPSCs. Our work also indicated that mean eEPSC PPR were substantially altered by STZ, effects which were partially restored by EDA. In contrast, no significant effects upon eIPSC PPR were obtained in response to STZ and EDA. Conclusion: Our data suggest that STZ inhibits glutamatergic transmission involving pre-synaptic mechanisms and AMPAR, and that STZ inhibits GABAergic transmission by post-synaptic mechanisms within CA1 pyramidal neurons. These effects are attenuated by EDA.

Abstract:

It has been demonstrated that stimulation of protein kinase A (PKA) results in enhanced synaptic transmission in the hippocampus and other brain areas. To investigate mechanisms of the PKA-mediated potentiation of synaptic transmission, we used rat hippocampal embryonic cultures. In low-density cultures, paired recordings under the perforated patch demonstrated that 15-min forskolin treatment produced long-lasting potentiation of evoked excitatory postsynaptic currents (eEPSCs) mediated by the cAMP/PKA pathway. eEPSC amplitudes increased to 240 ± 10% of baseline after 15 min of forskolin treatment (early). After forskolin washout, eEPSCs declined to a potentiated level. Potentiation was sustained for ≥85 min after forskolin washout and, 60 min after forskolin washout, constituted 152 ± 7% of baseline (late potentiation). Disruption of presynaptic processes with the whole cell configuration and internal solution containing PKA inhibitor peptide did not affect forskolin-induced potentiation. Disruption of postsynaptic processes, in contrast, impaired early potentiation and abolished late potentiation. Study of mEPSCs confirmed the contribution of postsynaptic mechanisms. Forskolin-induced enhancement of mEPSC frequency observed under the perforated patch was attenuated by the whole cell configuration. Forskolin also induced an increase of mEPSC amplitudes in the perforated patch, but not in the whole cell, experiments. Potentiation of eEPSCs was not activity dependent, persisting in the absence of stimulation. NMDA receptor blockade did not abolish forskolin-induced potentiation. In summary, we demonstrate that forskolin-induced potentiation of eEPSCs was mediated by postsynaptic mechanisms, presumably by upregulation of AMPA receptors by phosphorylation.

Abstract:

Cortical malformations are often associated with refractory epilepsy and cognitive deficit. Clinical and experimental studies have demonstrated an important role for glutamate-mediated synaptic transmission in these conditions. Using whole cell voltage-clamp techniques, we examined evoked glutamate-mediated excitatory postsynaptic currents (eEPSCs) and responses to exogenously applied glutamate on hippocampal heterotopic cells in an animal model of malformation i.e., rats exposed to methylazoxymethanol (MAM) in utero. Analysis revealed that the late N-methyl-d-aspartate (NMDA) receptor-mediated eEPSC component was significantly increased on heterotopic cells compared with age-matched normotopic pyramidal cells. At a holding potential of +40 mV, heterotopic cells also exhibited eEPSCs with a slower decay-time constant. No differences in the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) component of eEPSCs were detected. In 23% of heterotopic pyramidal cells, electrical stimulation evoked prolonged burst-like responses. Focal application of glutamate (10 mM) targeted to different sites near the heterotopia also evoked epileptiform-like bursts on heterotopic cells. Ifenprodil (10 μM), an NR2B subunit antagonist, only slightly reduced the NMDA receptor (NMDAR)-mediated component and amplitude of eEPSCs on heterotopic cells (MAM) but significantly decreased the late component and peak amplitude of eEPSCs in normotopic cells (control). Our data demonstrate a functional alteration in the NMDA-mediated component of excitatory synaptic transmission in heterotopic cells and suggest that this alteration may be attributable, at least in part, to changes in composition and function of the NMDAR subunit. Changes in NMDAR function may directly contribute to the hyperexcitability and cognitive deficits reported in animal models and patients with brain malformations.

Abstract:

Kainate (KA) receptors (KAR) have important modulatory roles of synaptic transmission. In the cerebellum, the action mechanisms of KAR-mediated glutamatergic depression are unknown. We studied these mechanisms by recording evoked excitatory postsynaptic currents (eEPSCs) from cerebellar slices using the whole-cell configuration of the patch-clamp technique. We observed that 3 μM KA decreased the amplitude of eEPSCs and increased the number of failures at the synapses established between parallel fibers (PF) and Purkinje neurons, and the effect was antagonized by NBQX under the condition where AMPA receptors were previously blocked. The inhibition of protein kinase A (PKA) suppressed the effect of KAR activation on eEPSC, and effect was not prevented by protein kinase C inhibitors. Furthermore, in the presence of Pertussis toxin, the depression of glutamate release mediated by KAR activation was prevented, invoking the participation of a Gi/o protein in this modulation. Finally, the KAR-mediated depression of glutamate release was not prevented by blocking calcium-permeable KARs or by treatments that affect calcium release from intracellular stores. We conclude that KARs present at these synapses mediate an inhibition of glutamate release through a mechanism that involves the activation of G-protein and protein kinase A.

Abstract:

Faced with dynamic and rapidly deteriorating environmental conditions, the government of Mozambique has embarked on environmental education programmes and campaigns (EEPCs) as a strategy for natural resource management and environmental conservation. However, there is increasing evidence to suggest that the implementation of these EEPCs in local communities are often lacking when it comes to community participation and contribution. The latter has often been cited as a major reason for the limited success of such EEPCs. To date there is little research work that explores the issues on the integration of local community Knowledge and practices, and community reactions to such environmental education programmes and campaigns anywhere in the world. Mozambique, a developing country in Africa, is no exception to this trend of ignorance. This research investigated the extent to which local knowledge and practices are integrated into The EEPCs that are implemented by the government of Mozambique. The focus was on the local community’s perceptions, engagements and reactions to the EEPCs. The study was conducted in four districts of the Nampula province in Northern Mozambique. The data were collected through in-depth interviews, documentary analysis and non-participant observations. The findings of the study showed that there is a lack of substantial involvement by the local community in all stages of the development process of the EEPCs. Furthermore, the study found evidence of partial and /or unsuccessful implementation of the projects in all four communities studied. The research concluded by arguing that without such active involvement of the local people in planning, designing, implementation, monitoring, evaluation and decision-making processes of EEPCs, the frustrations of government officials and the lack of substantial implementation of the projects in the communities that were studied should not have come as a surprise.

Abstract:

Ethiopian Electric Power Corporation (EEPCO), state owned monopoly that generates, transmits, and distributes and sales electric power nationwide, has been undergoing various continued utility management practices. One of the major improvements, as part of the transformation, was the introduction of Prepayment (Metering) System, over that of the conventional metering service, which had been forcing the Corporation to follow lengthy service processes, in order to support the realization of its long term strategic vision of providing quality electric service and being competitive in an energy export. However, despite the introduction of this new type of service-prepayment customer service, the Corporation has not been able to attract more than only about five percent out of the two million total customers. Therefore, this study tried to assess and analyze the existing practice (quality) of prepayment customer service both from the employee and the Corporation’s perspectives, and thereby propose possible marketing strategies that are capable of improving the customer service quality for the subsequent adoption of prepayment service. SERVQUAL, as a methodological approach to service quality measures, was employed to measure the prepayment service quality by comparing customers’ perception of the received service against their expectations. Accordingly, the study revealed, despite its limitations, that there has been a substantial gap between customers’ expectations and perception of the service rendered, for which different possible marketing strategies were suggested for improvement.

Full text

Abstract:

Even at low concentrations, the criteria air pollutant particulate matter (PM) is an environmental and public health hazard. Emissions levels legislated for modern diesel vehicles are so low (~90% lower than 2003) that it has become difficult to accurately measure PM by the regulatory metric: the mass of particles collected on a filter (i.e., the gravimetric method). Additionally, gravimetric analysis cannot measure real-time emission rates, and therefore is unable to characterize high-emitting transient events (e.g., engine starts, stop-and-go driving). By an alternate method, PM can be estimated by measuring the number-weighted particle size distribution (PSD) and calculating mass with a combination of theoretical and empirical constants (e.g., particle effective density). This integrated particle size distribution (IPSD) method is capable of high measurement sensitivity and real-time resolution. Real-time measurements by the IPSD method require fast-sizing spectrometers, such as the TSI Engine Exhaust Particle Sizer (EEPS), which sizes (between 5.6-560 nm) and counts particles based on their electrical mobility. The EEPS utilizes a unipolar charger to quickly charge particles for sizing and counting, however this mechanism has been shown to produce a less predictable charge distribution than bipolar chargers used in Scanning Mobility Particle Sizer (SMPS) systems – the gold standard 'slow-sizing' spectrometer. Several evaluations have shown deficiencies in EEPS PSD measurements due to charging differences (associated with particle morphology) unaccounted for in the transfer function matrix used to calibrate the EEPS. Specifically, the unipolar charger multiply charges a higher percentage of soot agglomerates (fractal-like particles common in diesel engine exhaust) than bipolar chargers. Because inaccurate PSDs are a primary reason for reported discrepancies between IPSD calculated mass and the gravimetric method, it is important to correct this deficiency in EEPS measurements. Recently, TSI has released additional EEPS calibration matrices ('soot' and 'Compact') which have shown better agreement with SMPS measurements under preliminary test conditions. This study further evaluates the performance of these new matrices relative to the original 'Default' matrix for diesel and biodiesel exhaust particles. Steady-state (75% engine load) emissions were generated by a light-duty diesel engine operating on (1) ultra-low sulfur diesel (ULSD) and (2) 100% soybean biodiesel. Raw EEPS data processed with each matrix were compared to simultaneously collected reference measurements from an SMPS. PSDs were evaluated based on their shape – i.e., multimodal fits of geometric mean diameter (GMD) and geometric standard deviation (GSD) – and concentration at peak particle diameter. For both fuels, all measurements agreed well in terms of the shape of the PSD: primary mode (accumulation) GMD ± 10nm, GSD ± 0.3. For ULSD, EEPS Default, Soot, and Compact concentrations were higher than the SMPS by factors of 1.9, 1.3, and 2.5, respectively. For biodiesel, EEPS Default, Soot, and Compact concentrations were higher than the SMPS by factors of 2.1, 1.7, and 2.4, respectively. Based on these results, the Soot matrix produced acceptable agreement between EEPS and SMPS measurements of ULSD exhaust particles. However, based on the factor of ~2 difference observed here, an additional calibration matrix may be necessary for the EEPS to accurately measure biodiesel exhaust particles. The IPSD method for estimating PM mass was applied to available data sets with corresponding gravimetric measurements (one ULSD transient cycle test and the same biodiesel steady-state test used for PSD evaluation). Real-time PSDs from each of the three EEPS matrices were used in combination with three sets of values assumed for size-dependent particle effective density (representing a range of potential conditions), resulting in nine IPSD estimates of PM mass corresponding to each gravimetric sample (one ULSD, one biodiesel). For the transient ULSD test, a widely used effective density distribution for fractal-like soot agglomerates resulted in good agreement between IPSD estimated mass and the gravimetric measurement (within 9% and 6% for Soot and Compact matrices, respectively). For the steady-state biodiesel test, assuming unit density (1g/cm³ for all particles) resulted in good agreement between IPSD estimated mass and the gravimetric measurement (within 7% and 2% for Soot and Compact matrices, respectively). These results support previous findings that the Soot matrix is currently the best available option for measurement of ULSD exhaust particles by the EEPS and that particle effective density distributions similar to the "fractal-like" one used here are an accurate estimate for ULSD exhaust particles under many conditions. However, based on the discrepancies between the EEPS and SMPS measured biodiesel exhaust PSDs observed here, as well as a current lack of information on the effective density of biodiesel exhaust particles, it is clear that additional research is necessary in order to understand the properties of biodiesel exhaust particles, especially as they relate to electrical mobility measurements and IPSD estimation of PM mass.

Full text

Abstract:

The majority of organizations make their business processes explicit to improve them. Defining business processes manually and modeling them are two alternatives utilized for this purpose. Meanwhile, organizations have quality management systems which are frequently shaped by frameworks. The most commonly used process improvement frameworks in the IT sector are ITIL, Cobit, CMMI and ISO 9001. These frameworks indicate the necessity of process documentation and ISO 9001 addresses the name &ldquo
Quality Manual&rdquo
for this purpose. In this thesis, an automated tool is developed for quality manual generation from predetermined business process models. In addition, a case study is performed by means of a systematic approach and its results were discussed with the findings of structured interviews. The aim of the study is to reduce the effort and time required for quality manual preparation and merge quality management activities with process modeling by means of process documentation.

Economically, the country depends almost entirely on a single natural resource i.e. oil, which will be eventually exhausted. About sixty seven percent of Saudi’s native population is under 30 years of age and about 30 percent of 15-29 years old Saudis are unemployed. The country thus needs to diversify its economy and create job opportunities for its young unemployed population. A way forward in this regard could be supporting and promoting young people to engage in economic and entrepreneur activities, which could be facilitated by entrepreneurship education. Entrepreneurship has long been considered as a driver of innovation, a generator of employment opportunities and a potential wealth creator for both individuals and organisations. Academic literature supports the belief that with appropriate entrepreneurship education the number of would-be entrepreneurs can be increased. This study investigated the impact of entrepreneurship education programmes (EEPs) on entrepreneurial attitudes and intentions amongst university students in the KSA. The conceptual model tested in this research was based on the Theory of Planned Behaviour. Based on a quantitative approach, a self-administered questionnaire was distributed to two groups: participants studying entrepreneurship courses as part of their degrees (to be known as EEPs Group) and participants not undertaking any entrepreneurship studies as part of their courses (Control Group). The data collection took place at the beginning of the semester (Pre-test/t1) in April 2010 and at the end of the semester (Post-test/t2) in July 2010. After screening, a final matched sample of 491 completed questionnaires for the EEPs Group and 184 for the Control Group was used for data analysis. The results of this empirical study revealed that the intention to become self-employed was positively and significantly correlated to attitudes regarding self-employment, to subjective norms and to perceived behavioural control. However, for entrepreneurial education, the intention to become self-employed was neither positively nor significantly correlated with new business start-up activities. For policy-makers in KSA, the study provides useful insights into the situation of entrepreneurship education, will aid planners in universities and the KSA government to address unemployment of young by creating greater entrepreneurial awareness, and thus, hopefully, jobs through entrepreneurship activities. This study has confirmed that EEPs has a significant contribution in developing entrepreneurial attitudes among university students. Thus, entrepreneurial skills could be inculcated in the younger Saudi generation early on in their lives by institutionalising enterprising and entrepreneurship knowledge, skills and culture through education and learning starting from the high school level to the university level. In addition, there is a need for changing behaviour and intentions towards, and creating awareness about, entrepreneurship and self-employment among Saudis using different channels of communications such as the electronic media including the social media.

Abstract:

Poor integration of pedagogical and technological learning elements within teaching and learning methodologies may have substantial impacts on the effectiveness of learning. Although educational institutions are improving their courses, teaching and learning methodologies and assessment strategies with tailored approaches, their efforts at improvement tend to focus narrowly on academic results. The authors believe that educational courses should give priority to educational goals and labour market expectations (industrial companies’ requirements) in devising the methodology of teaching and learning. The technology based learning system has a capability to comply with diverse requirements as mentioned. The purpose of this paper is to develop an extended information quality framework to measure the effectiveness of e-learning content for technology based learning system for engineering education courses (EECs) in Technical and Vocational Education (TVE) in Bahrain. The model incorporates the requirements of educational goals (TVE goals) and modern industrial needs and integrates these with existing information quality frameworks. The extended model incorporates pedagogical and technological elements, is consistent with the educational objectives and industrial requirements, and can be used as guidelines for measuring the effectiveness of e-learning packages delivered in EECs.

Abstract:

The chapter on brain-gut-microbiome (BGM) axis communication analyzes the interactions between the gut microbiome, the regulatory processes within the gut (including the enteric nervous system [ENS], enteroendocrine cells [EECs], and immune system), and the central nervous system (CNS) (including the brain, hypothalamic-pituitary axis [HPA], and autonomic nervous system), both in brain development and in health, such as modulation of emotional states and ingestive behaviors, and in disease, such as autism spectrum disorder (ASD), irritable bowel syndrome (IBS), Parkinson’s disease, and obesity. Special emphasis is placed on new developments in our understanding of the role that the gut microbiome plays within the BGM axis.

Abstract:

The purpose of this chapter is the study of the clustering process in Wireless Sensor Networks (WSN), starting with clarifying why there are different clustering protocols for WSN by stating and briefly describing some of the variate features in their design; these features can represent questions the clustering protocol designer asks before the design, and their brief description can be considered probabilities for these questions’ answers to represent design options for the designer. The designer can choose the best answer to each design question or, in better words, the best design options that will make its protocol different from the others and make the resultant clustered network satisfies some requirements for improving the overall performance of the network. The chapter also mentions some of these requirements. The chapter then gives illustrative examples for these design variations and requirements by studying them on three well-known clustering protocols: Low-Energy Adaptive Clustering Hierarchy (LEACH), Energy-Efficient Clustering Scheme (EECS), and Hybrid, Energy-Efficient, Distributed clustering approach for ad-hoc sensor networks (HEED).
