The Security Parameters and Aspects of Mobile adhoc networks - A Detailed Review []


The Mobile adhoc network is the sort of arrange in which portable hubs can connect or take off the arrange when they need. Due to self-designing nature of the malicious hubs enter which are capable to trigger different sorts of active and passive nodes. The active attacks are those which decrease network performance in terms of certain parameters. In this paper, different procedures are looked into and analyzed in terms of certain parameters.

The Critical Evaluation of the Influence of Classical and Human Relations Approaches In Management Today. []


According to the Business Dictionary, “Management is the Organization and coordination of the activities of a business in order to achieve defined objectives”. Organizations’ accountability and profitability depend on how well the business is managed. To make the Organization profitable and accountable, effective leadership, controlling the business efficiency and develop or strategize the business are the main bridges of today`s management and those of the classical and behavioral management (Yacoub, 2016, p.2). As Yacoub delineated in its dissertation, even if there are many similarities between today`s management and management in the past centuries; globalization (competitive advantage), learning and innovation, technology encroachment and organizational arrangement require vast management approach than those of the classical and human relations approaches of the past (Yacoub, 2016, p.2). The three major pillars which connects or familiarize the modern and post-modern management with that of the past management approaches directly or indirectly have an influence on the Organization's performance. As indicated by Karlof and Loevingsson, efficiency and effectiveness are core concepts for Organizational performance. Organizational performance generates a distinctive value in a manner in which the benefits of producing the value outweighs its cost. (Karlof and Loevingsson, 2005, p.6). To create a unique value of the Organization, the application of management approaches matter to ensure the future success of the business. According to Rahman, improving economic competence through workers efficiency and optimum utilization of resources is a primary concern of classical and human relations management approaches in order to get up a significant Organization dependable with the wellbeing of entrepreneurs, employees, and customers at large (Rahman, 2012, p.6). Yacoub also depicted “the connection between worker motivations and individual/group performance” by supporting the works of (Cole and Kelly, 2016, p.16) and Mechaelson, (2005). The early theories of management regarding to human-relations theories were more concerned in the human factor at work; their center was on the individual satisfaction and motivation as much as efficient use of resources which leads to effectiveness of operations (Yacoub, 2016, p.3). This essay critically evaluates the influence of classical and human-relations approaches adopted by Organizations specifically for the case example of Toyota Company by clearly showing how classical and human relations approaches impact on management and practice today. The essay does not cover all classical and human-relations approaches rather identify and focus on the main themes of those approaches. We assess the relevant practices, policies, and approaches of Toyota and We show how the classical and human-relations theories are reflected in the company`s policies.

The Extent to Which the Creation, Sharing, and Utilization of Knowledge are Central to Resource-Based View of Competitive Advantage, A Critical Evaluation. []


According to the Business Dictionary, “Management is the Organization and coordination of the activities of a business in order to achieve defined objectives”. Organizations’ accountability and profitability depend on how well the business is managed. To make the Organization profitable and accountable, effective leadership, controlling the business efficiency and develop or strategize the business are the main bridges of today`s management and those of the classical and behavioral management (Yacoub, 2016, p.2).

Yacoub also depicted “the connection between worker motivations and individual/group performance” by supporting the works of (Cole and Kelly, 2016, p.16) and Mechaelson, (2005). The early theories of management regarding to human-relations theories were more concerned with the human factor at work; According to Dasgupta and Gupta, continuous learning is the only way to deal with a changing environment in Organizations. They have also pointed out that the level of the Company`s competitiveness, innovativeness, and product introduction success increases when the learning ability of a Company is higher. There are social and economic challenges that the organization faces. In order to tackle and cope up with these challenges, the organization must have an expansive spectrum of competence that included knowledge. The profundity and assortment of this knowledge can be enhanced through continuous learning (Dasgupta and Gupta, 2009, p.207). Dasgupta and Gupta have described the phases of the learning process into four steps. (1) The identification of relevant information that is necessary for learning and new knowledge creation. (2) The sharing and dissemination of knowledge either from individual to the group or at the group level itself. (3) Knowledge incorporation into the existing system of the Organization knowledge procedure and rules at individual or group level in order to make the implementation of the system can take place. (4) Lastly, the application of the new knowledge into the routines of the organization to make a change on the organizational behavior (Dasgupta and Gupta, 2009, p.208). They used two perspective researchers to elaborate on the key processes of learning which have been stated above. The works of Anderson and Boocock (2002), and Nonaka (2000) on the one side and the works of Yeung, Ulrich, Nason, and Glinow (1999) on the other side. As cited by Dasgupta and Gupta, the first researchers suggest that communication channels are the key elements in organizational learning. These communication channels help individuals to make questions instead of relying on unapproachable implicit knowledge. On the other side of the suggestion, organizational learning depends on strategic options. According to this suggestion, there is no one way of learning styles-the the preferred learning styles changes with the strategy of an organization. In addition to these two perspective researchers`, there was also another dimension of a new learning perspective by Wilson (2007). According to this perspective, there is a concept of ‘Learning With’-the creation of new knowledge through collaboration and active process rather than on the recycling of existing knowledge introduced by former researchers (Dasgupta and Gupta, 2009, p.208). Although, knowledge is created in a manner that discussed above in different perspectives, it should be shared and utilized correctly to bring the desired competitive advantage. As per Dasgupta and Gupta “innovation is a prerequisite for competitive advantage” (Dasgupta and Gupta, 2009, p.206). To share and utilize knowledge in a manner that change taken in to account in the organization ‘Knowledge Management’ is a crucial concept as it is addressed in most literatures. Without sound knowledge management it is difficult to achieve innovation which comes from the application of new ideas (Dasgupta and Gupta, 2009, p.216). In this short thesis, we cover the extent to which the creation, sharing, and utilization of knowledge is central to competitive advantage. As explained earlier the competitive advantage achieved through innovation. To successfully result for the desired innovation, new knowledge should be created, shared, and utilized so that we need to have proper utilization of this resource-knowledge management. Through knowledge management, we are going to cover the four pillars of knowledge management and organizational learning-organization structure, organizational culture, technology, and leadership skills (Dasgupta and Gupta, 2009, p.216). These pillars support knowledge management and organizational leadership by excavating tacit knowledge, which is in the minds of the knower, difficult to manage (Luthans and Youssef, 2004, p.7).

Establishing and Applying a Leadership Style to an Organization and the Actions to Take []


As Alexander the Great quoted “I am not afraid of an army of lions led by a sheep rather I am afraid of an army of sheep led by a lion” (UNICAF, topic 1, p.7). This quote shows how much leadership plays a significant role in organizational performance. Indeed most organizations do not figure out the significance of leadership and as a result, fails to achieve organizational objectives. Leadership has been defined by many scholars and authors in a different way in the past. Among the recent definitions and the one stated by UNICAF University Strategic Leadership and Practice Module Week 1 by referring the definition of Lussier and Achua (2015, p.5); “Leadership is the influencing process between leaders and followers to achieve organizational objectives through change” As we can understand from the definition, leadership is a kind of influencing process for the attainment of organizational goals. In order to influence subordinates and stakeholders within the organization leadership style is an undeniable component which leads the coordinated effort to successful achievement. Without effective leadership style and successful application within the organization leaders may not guide themselves towards the attainment of organizational goals (UNICAF, Topic 1, p.7). In this essay, we are going to cover a range of leadership styles and the impact of each leadership style on the organization's performance and productivity of employees. Then after, we go through each leadership style evaluation critically and suggest as well as apply to the presumed Company that I am considered to be a new senior manager that having 57 employees under my leadership.

Analyses of Mineral Elements in Some Plant Tissues obtained from Yankaba and Janguza Markets of Kano Metropolis, Nigeria []


Mineral elements are elements in form of minerals salts required by plants for normal growth and development and their deficiency can easily manifest on plants. Twenty (20) different samples of plant tissue from Yankaba and Janguza markets of Kano State were analyzed for the level of Cu, Fe, Zn, Mn, Ca, Mg, K and Na. These elements are grouped into heavy metal (Cu, Fe, Zn, Mn) and light metals (Ca, Mg, K, Na) that affect the well being of plants and ani-mals at high concentrations. Based on persistent nature and cumulative behaviour of these elements, there is need to test and analyze food items to ensure that the level of these ele-ments meet international stanards. This is particularly important for farmers in West Africa where only limited data are available. The level of Cu, Fe, Mg, Zn,Ca and Mn were determined by atomic absorption spectroscopy while that of K and Na were determined by flame photo-metric method. Samples from Yankaba market indicated highest mean levels of Cu (0.100mg/g), Fe (0.230mg/g), Zn (0.088mg/g), Mn (0.085m/g), Ca (2.661mg/g), Mg (1.660mg/g), K (1.06mg/g) and Na (2.302mg/g). While those from Janguza market indicated highest levels of Cu (0.820mg/g), Fe (0.082mg/g), Zn (0.044mg/g), Mn (0.040mg/g), Ca (1.725mg/g), Mg (0.467mg/g), K (0.286mg/g) and Na (1.385mg/g). Comparison of the results obtained from the two markets showed that the mean concentration of the mineral elements of plants tissues obtained from Yankaba markets were generally lower than that of Janguza market.

Many new algorithms advised and used in the cloud computing which have made the cloud computing more safe for the people and prevented many privacy attacks.

PERCEPTION OF MEN AND WOMEN ON GENDERED ACCESS AND CONTROL OF LAND AND DAIRY PRODUCTS IN MURANG’A COUNTY, KENYA []


This study sought to investigate men's and women’s perceptions on gendered access and control of land and dairy products in Murang’a County-Kenya. It was guided by the Marxist feminism theory advanced by Friedrich Engels (1884) and Women Empowerment Framework (WEF) by Sarah Longwe (1991). The study utilized a cross-sectional research design. Further, purposive sampling technique was used to select Kigumo Sub-county as the area of the study, out of the six sub-counties in Murang’a County. Additionally, a simple random sampling technique was used to select four hundred and forty-two (442) male and female headed households, practicing dairy farming in the Sub-county to participate in the study. Also selected to participate in the study were the community leaders and key county officers as key informants. Study instruments utilized for the purpose of generating the required data were interview schedules for the selected male and female household heads, a guided questionnaire for the key informants, and an observation checklist. Data were analyzed both qualitatively and quantitatively. Data analysis revealed that male and female household heads held different perceptions in relation to gendered access and control to land and dairy products, with a bias against women. The perceptions were found to have been mostly influenced by culture, religion, lack of awareness on legal requirements, and individuals’ level of formal education.

COMMERCIALLY AVAILABLE HERBAL PREPARATIONS USED IN THE TREATMENT OF TYPHOID FEVER IN THE NORTH WEST REGION OF CAMEROON: DETERMINATION OF THE IN VITRO EFFICACY []


ABTRACT The use of herbal preparations is gaining popularity, with an estimated 80% of the world’s population still depending on herbal medicine for the treatment of various diseases. However, data concerning their quality, safety and efficacy is not readily available. Aim The main aim of the study was to determine the in vitro efficacy of some commercially available herbal preparations used in the treatment of typhoid fever in Bamenda. Materials and methods Five herbal preparations indicated for the treatment of typhoid fever (coded P1 – P5) were bought from various outlets of the herbal producers and serial dilutions made and screened for their activities against clinical isolates of Salmonella typhi and Salmonella paratyphi using the agar well diffusion and agar dilution methods. The inhibition zone diameters of the herbal preparations were measured with a transparent ruler and compared with that of some standard antibiotics (ciprofloxacin and ceftriaxone). Results Two of the herbal preparations (P1 & P2) showed inhibition zone diameters against S.typhi while the rest (P3, P4 & P5) were in active. On S.paratyphi, P1 showed minimal activity while the rest of the herbal preparations (P2, P3, P4 and P5) were inactive. The difference between the value of the inhibition zone diameters of the herbal preparations and that of the standard antibiotics on both S. typhiand S. paratyphiwas statistically significant (p< 0.05). Conclusion It was found out that most of the herbal preparations showed no activity against the test bacterial isolates contrary to their label bogus claims. Keywords: Herbal preparations, Salmonella typhi, Salmonella paratyphi, typhoid fever ceftriaxone).

Catch Composition of Drift Gillnet in Tanjungpandan Waters, Belitung Regency []


This study aims to determine differences in the catch composition of drift gillnet with the operating time in the evening and night and oceanographic parameters at the study site. The research method used was experimental fishing with data processing using t-test which was then analyzed descriptively. Catching activity were carried out in August - September 2019 in the waters of Tanjungpandan, Belitung Regency. The total catch of fish during the study was 1027.8 kg or 880 fish. The types of fish caught and the amount of each fish based on weight during the study were narrow-bared Spanish mackerel (Scomberomorus commerson) 36.96%, kawakawa (Euthynus affinis) 34.97%, dorab wolf-herring (Chirocentrus dorab) 2.30%, Indo-Pasific sailfish (layIstiophorus Platypterus) 2.29%, mackerel (Rastrelliger sp) 4.07%, whitecheek shark (Charcarhinus dussumieri) 15.80%, and mahi-mahi (Coryphaena hippurus) 3.62%. The results of oceanographic parameter measurements at the study site are sea surface temperature (SST) ranging from 28 - 30°C in the evening and 30 - 32°C at night, salinity ranges between 28 - 32ppt in the evening and 30 - 31ppt at at night, the brightness ranges from 6 - 8 m in the evening and 5 - 7.5 m at night, and the depth of the waters ranges from 32 - 34 m. T-test results with α = 0.05, dk = 26 and Ttable= 1.70 get the value of Tcount= 4.65 based on the total weight and Tcount= 2.77 based on the number of fish so Tcount> Ttable so H0 is rejected and H1 is accepted, which means that there is a significant difference in the catch of the drift gillnet in the evening and at nigh based on the total of the weight and individuals.

CHINESE ‘DOLLAR’ INFLUENCE IN AFRICA, IMPLICATION FOR TAIWAN-NIGERIA TIES []


The dawn of the twenty-first century begun at a time when the global population rises to over 7.2 billion people out of which Asia and Africa account for more than 60 percent of the entire figure. The China’s rapidly growing economy since 1970s, and the nature of exporting its end-goods to the global markets including in Africa coupled with the large investments in multiple sectors throughout the region confirm Sino-Africa mutual closeness in terms of trade pattern. This study aims at exploring how hardest the severance from Nigeria could generally affect Taiwan-Africa relations at a larger scale. It nevertheless, proposes to examine how much authentic the afterthought that democracies don’t go to war, is, and whether if they go to diplomatic bust-up for economic reasons. This study concludes that the leading forces behind the Nigeria’s abrupt changing attitude towards Taiwan is China’s dollar policy. It also finalizes that the Afro-Taiwan political and diplomatic dancing may have so much impacts on Taiwan sovereignty at the international level.

Production drilling performances at Kinsevere []


This article is about the blastholes drilling productivity at the mines of Kinsevere. These mines planned to produce 60,000 tons of copper cathodes per annum, although they produced around 75,000 tons in the last three years. Drilling is the first operation in the mines, and analysis of this operations should reveal if they are working at the optimal level, or they need some improvement. The performances of the Drill Rigs, The Pantera 1500 i, are 95.78 mph in average with standard deviation of 46.17, a minimum of 29.64 mph in fresh cellular siliceous rock, a maximum of 367 mph in dolomitic shale, a median of 93.64 mph in weathered cellular siliceous rock. These are quiet high compared to the 30.5 mph in standard conditions. 300 samples measures have been sampled on site, and 30 samples of utilizations and availabilities have been analyzed for these conclusions. On the scale of standard drilled meter, with 4 categories of rock among T2 for very soft is witch free digging is executed, T2D for soft rock requiring small powder factor, T3 medium rocks required relatively high powder factor, and T3D hard rock requiring high powder factors, the standard drilled meters at Kinsevere is calculated by the formula: SD=0.21 T2+0.28 T2D+0.36 T3+0.47 T3D Keywords: Standard Drilling, Performances, Utilization, Availability.

Petrology of the Igarra Metaconglomerate: Implications for tectonic history, provenance and source materials. []


Petrographical and geochemical characteristics of the Igarra metaconglomerate have been examined to reveal their tectonic history, provenance and source materials. Field and laboratory petrographic studies revealed that mineral association in both matrix and clast of metaconglomerate are characteristic of low to medium grade of metamorphism. Fifteen (15) samples each of matrix and clast of Metaconglomerate were selected for geochemical analysis. This involved the use of ICP-MS and ICP-AES to analyze from solution, using a modified aqua regia (1:1:1 HNO3: HCl:H2O), a partial digestion that provided valuable information regarding mobile and easily soluble species, such as sulphides and checking results by internal and external standards. Metaconglomerate have clasts of different sizes ranging from pebbles, cobbles and boulders which are polyminctic in character. Most of the pebbles are quartzitic and granitic composition but pebbles and boulders of calc-silicate gneiss and carbonate compositions were also observed. Most of the pebbles are quartzitic and granitic composition but pebbles and boulders of calc-silicate gneiss and carbonate compositions were also observed. The deformed conglomerates are typically matrix-supported (with approximately 60 to 80 % matrix by volume) Qualitatively, the grain size of the clasts is in the order quartz > granite > carbonate. Quantitatively, strain varies throughout the region and between clast types, with the strongly strained clasts usually in spatial proximity to ductile shear zones. Majority of the samples plots in the L = S tectonite field with the percentage range of 50% and 70%. In their discriminating binary diagram using the DF1 vs DF2 functions, the analyzed samples from both matrix and clast of the Igarra metaconglomerate fall into the field of quartzose sedimentary provenance. Samples of matrix of the metaconglomerate plot in the arkose field while those of the clast plot between arkose and greywacke. This spread of the clast is attributed to the heterogeneous nature of their source material which indicate difference in composition. In the plot for tectonic setting, clast favor the field corresponding to passive continental margin settings while the matrix is plotted in the Island Arc environment of continental nature. Based on the geochemistry of the samples from the metaconglomerate of the Igarra schist belt, a derivation of the detrital material from intermediate rocks on the upper continental crust with occasional tilt towards either felsic or mafic affinity is postulated.

A Rare atypical Case of Low-grade Appendiceal Mucinous Neoplasm: A Case Report []


Introduction Low grade Appendiceal Neoplasm (LAMN) can present as a painless appendicular abscess .If painless and shows good antibiotic response can be managed conservatively with interval laparoscopic appendectomy. Presentation of case: A 65year woman with known history of hypertension, non-diabetic presents in OPD with lethargy, malaise, loss of appetite, dark coloured urine and low grade fever for a week since onset. Initial bloods revealed only raised CRP (>100 /mg/dl < 150 /mg/dl) and few RBCs in urine. An empirical 7 days course of oral cephalosporins was started. Patient condition didn’t normalized and detailed workup showed a large fluid filled collection in right illaic fossa raising suspicion of ruptured appendix with abscess formation, mucocele/pyocele of the appendix remained in the differentials. However, keeping in view patient’s age possibility of neoplastic disease process could not be ruled out. Repeat bloods showed raised TLC and CRP. IV antibiotics (Meropenum) was started, patient started improved clinically and TLC normailised and CRP showed downward trend. Patient was thus advised to complete 10day IV antibiotic course with a repeat CAT scan showed marked improvement in fluid collection in right iliac fossa which meant good antibiotic response. Follow up scan on monthly basis showed almost complete resolution of Right Iliac Fossa collection .Interval appendectomy was performed and H/P showed Low Grade Appendiceal Neoplasm .Post op colonoscopy was non - significant. Discussion Low grade appendiceal neoplasm can present as painless appendicular abscess and can be managed conservatively and with interval appendectomy smoothly. Conclusions LAMN can present from asymptomatic condition to painless appendicular abscess or acute appendicitis and as Pseudomyxoma Peritoni. Management varies according to clinical presentation.
