External auditory canal cholesteatoma is a very rare entity, representing 0.1 to 0.5% of the otological pathology, carrying the same characteristics as that the middle ear cholesteatoma. Its location may be associated to other affections due to the large variety of differential diagnosis, benign or malignant cases which are far more frequent than the cholesteatoma. The diagnosis is mainly clinical, the therapeutic management consists on a surgical procedure which depends on the stage of the disease. Known for its slow evolution, and the risk of recurrence, the external auditory canal cholesteatoma requires a clinical and radiological surveillance that can extend over several years. Our work focuses on the study of diagnostic modalities and therapeutic management through two hospitalized cases treated in the ENT and CCF department of Rabat Specialty Hospital.

Migration of fishermen is common in the Kenyan waters of Lake Victoria. It affects the way people use and manage this natural resource. But little attempt has been made to relate migratory behavior of fishermen and the impacts of migration on fisheries conservation and management. This paper observes that fisheries related migration has some triggers. The paper therefore analyses the causes as well as demographic characteristics of fishermen using neoclassical economic theory and Logit model. Results show that fishermen have fishing as a primary source of income and are likely to be less literate. It is also shown that migration among fishermen is male dominated and has a clear gender-labour division. Further investigation revealed that migration reduces the positive attitude towards management of the common property. It is always assumed that population is the main driving force behind migration. But this paper further reveals that age, income and educational level, experience and family size are the main determining factors towards long/ permanent fisheries related migration. In relation to educational level, it is noted that those who have been for long and still in fishing is because they are illiterate and have been involved in fishing from their childhood and therefore lack other skills. It is concluded that there is a significant relationship between migration variables of fishermen and the reduced efforts towards conservation in Lake Victoria fishery. It is thus recommended that, since there is no clear sign to halt fishermen’s migration in Lake Victoria, there is therefore a need to create public awareness to improve knowledge of the dangers of migration to fisheries conservation and management.

Elderly become more vulnerable to malnutrition and ill health as they grow older. This study was done to assess the functional and nutritional status of institutionalized elderly. The study was conducted in 100 (65 females) elderly aged 78.6 ± 6.9 years. Males had higher height, weight, fluid intake and better functional status (p<0.05). Females had higher fasting blood sugar, HDL cholesterol and proteins (p<0.05). In Mini Nutritional assessment (MNA), females were found more malnourished (p<0.05). Institutionalized Males have better functional and nutritional status as compared to females.

Development of molecular markers for various desirable traits related to disease resistance, drought tolerance, compact canopy, higher yield, etc hold great potential for crop improvement of Casuarina equisetifolia L. This work focuses on the analysis of genetic relationship between 24 first generation colones of C. equisetifolia. Total genomic DNA was isolated by CTAB method and amplified with random oligonucleotide primers (Ten arbitrary 10-mer primers from Oberon Technologies Primer, USA) using PCR. The polymorphic bands were detected on agarose gels. Each random primer used in this study produced distinct bands. These were used for the final analysis. Six primers (OPM-05, OPM-13, OPB-18, OPE-06, OPE-07 and OPE-08) yielded 39 scorable bands. These bands were then constructed using the RAPD distance v1.04 package. Following this, SHAN method in NTSYSpc v2.02 was used to generate a pair wise distance matrix between various clones of C. equisetifolia. The highest genetic similarity co-efficient value (0.91) was observed between clones APSKLM-25 and APVSP-14 while the lowest co-efficient value (0.04) was seen between clones APKKD-11 and APKKD-9. The RAPD study was helpful to establish clonal identify.

Biosynthesis of silver nanoparticles using Diospyros chloroxylon Roxb. ripened fruit pulp of extract was investigated and the effect of broth concentration in reduction mechanism and particle size is reported. The rapid reduction of silver (Ag+) ions was monitored using UV-visible spectrophotometer and showed formation of silver nanoparticles within 20 minutes. Transmission electron microscopy (TEM) showed that the synthesized silver nanoparticles are varied from 10-25 nm and have the varying in shapes like spherical, round uneven. Further the XRD analysis confirms the nano-crystalline phase of silver with FCC crystal structure. FTIR examinations confirms the Silver particles. The present study, it was found that the increasing broth concentration increases the rate of reduction and decreases the particle size.

Single crystals of pure Zinc Tris-thiourea Chloride (ZTC) and L-alanine- doped ZTC were grown from aqueous solutions by slow evaporation technique. The grown crystals have been subjected to single crystal x-ray diffraction to determine the unit cell dimensions. The Fourier Transform Infrared (FT-IR) spectra has been recorded in the range 400-4500 cm-1. Morphological alterations have been observed when L-alanine was doped into ZTC crystals. UV-Visible spectrum shows that the grown crystals have wide optical transparency in the entire visible region. The grown crystals were also subjected to other characterizations such as micro hardness, thermal and NLO studies.

An equestrian sport is one of the interesting outdoor activities. This sport is one of the expensive co-curricular activities but the benefits are undeniable either to normal people or disable. The purpose of this study is to enlighten on the advantages that we get from participating in this sports, in terms of health, personal skills and even horses were used as a medium to help people with disabilities. This co-curricular activities also can help us to improve our skills either generic skills or technical skills.

Brexit is a fact and Bulgarian political scientists are left to answer the question, how EU after Brexit should be communicated to citizens and especially to students. What will the impact be in the spheres of politics and economic. There is a need for political changes on our everyday life and the need of mor? solidarity, cons?nsus and compromis? in political d?cision making. Events such as Br?xit ar? n?w in th? ?U Studi?s. One way to analyze them better in class is with the stud?nts engaging in th? act of "making politics". This chapter explains the chall?ng?s faced by political scientists which is to ?nsur? that th? stud?nts will b? provid?d with th? n?c?ssary toolset to pr?par? th?m to b? activ? European and global citiz?ns.

Like almost every other writer, Virginia Woolf and Hélène Cixous were also products of their respective times and cultures, and had their own ideologies as to how to ‘liberate’ women through writing. Writing apart by about fifty years, both of these European writers have felt for and contributed to the cause of women upliftment. This submission evaluates their stances in terms of their commonalities as well as differences. Though, their prime concern, fight and hopes remain the same – emancipation of women and her writing, both standing free against the shackles of patriarchy. A Room of One’s Own, often called the ‘Feminist Bible’ stresses largely on economic independence and privacy as crucial pre-requisites for a woman-artist to be able to write fiction of any merit, rising beyond psychological obstacles. Cixous in “The Laugh of the Medusa” employs a more revolutionary tone, asking for women to bring their bodies, hearts and minds into speech and writing. Women must shatter the framework of institutions, blow up the law and re-define truth. Only then, the dreaded Medusa, on closer inspection, will appear both, beautiful as well as laughing.
