Zero divisors of support size 33 in group algebras and trinomials divided by irreducible polynomials over GF(2)GF(2)

A famous conjecture about group algebras of torsion-free groups states that there is no zero divisor in such group algebras. A recent approach to settle the conjecture is to show the non-existence of zero divisors with respect to the length of possible ones, where by the length we mean the size of the support of an element of the group algebra. The case length $2$ cannot be happen. The first unsettled case is the existence of zero divisors of length $3$. Here we study possible length $3$ zero divisors in rational group algebras and in the group algebras over the field with $p$ elements for some prime $p$

Childbirth choice and effect of education

Annually, many women become pregnant worldwide; however, pregnancy and childbirth is not a pleasant event for all them. In fact, more than 90 of maternal anxiety could be related to the delivery process. It should be noted that delivery is also a stressful event that sometimes, due to different reasons and in order to avoid its potential hazards which could threaten the lives of mother and baby, it is not possible to deliver through the natural channel and Caesarean section delivery is necessary. However, nowadays, many of cesarean sections are unnecessary. The unnecessary cesarean delivery has an important impact on maternal and neonatal health and reducing (unnecessary) caesarean section is one of the health priorities. That’s why many countries are trying to reduce unnecessary cesarean and promote natural childbirth. In Iran, Maternal Health Office at Ministry of Health and Medical Education in 2002, initiated the design of a national program for mother-friendly hospitals to reduce the cesarean rate by 25 until 2015. In addition, previous research has shown that through education of mothers and reducing their fear about childbirth and correcting some wrong beliefs about natural childbirth, the unnecessary cesarean section could be reduced. By systematic training to control of the fear and anxiety in pregnant women, they will believe that they have ability to do natural childbirth and in turn could increase their self-confidence. Finally, it will lead to increased cases of vaginal delivery

The Crown of Loss

In many patriarchal, Eastern cultures, marriage has been idealized and beautified as a means of escape for girls and young women. Marriage has been propagated as a way out of the restricted life girls often experience under the harsh surveillance of male family members, especially fathers and brothers. Hence, many Eastern cultures, particularly the more patriarchal and restricted ones, often witness the formation of the “Cinderella Complex” in girls. Many girls come to believe that marriage can help them realize their suppressed dreams. As a result, girls often focus on attracting male attention instead of focusing on cultivating their talents. Yet they often become disappointed after marriage, finding themselves in a close replica of the past lives they were trying to escape, but with even more duties, higher expectations, and even less leisure time. Patriarchal societies have silenced this truth for years to benefit men with younger brides of less experience who tend to be more naive and malleable and, thus, more compliant. This silence surrounding the realities of marrying young has proved devastating for Eastern girls, leading to life-long regrets. Having wasted their time and talents only to get married, many girls are left broken and hopeless, without their own talents and means to survive on their own, and in a marriage that mirrors the circumstances they were trying to escape in the first place

A Comparative Study of Psychiatric Disorders and Coping Strategies between HIV Patients and Healthy Subjects in Khorramshahr

Introduction: HIV infection is a common viral infection that affects humans and is one of the main causes of premature death, with a tremendous growth, particularly in Africa and developing countries and among young populations. In addition to the underlying factors, individuals' psychological traits and inability to cope with stressful situations are supposed to be among the accelerating factors in people with the disease. The aim of this study was to compare HIV patients with psychiatric disorders and coping strategies with healthy subjects in Khorramshahr, Iran Methods: The subjects were purposefully selected. The tools were SCL90 and problem solving skills questionnaires. Subjects filled out both questionnaires individually. To compare psychological symptoms and quality of life between the groups , multivariate analysis and regression analysis were used . Findings: The results showed that there was a significant difference between the two groups in obsessive scale (p =0.034 and T =2.18) and fear (p=0.04,T=2.11).Moreover, both groups were significantly different in strategies for coping stress, that is Problem-oriented coping style (p = 0.00 and T=4.631), emotional (p= 0.01 and T=2.566) and avoidant (p=0.02,T=-2.358). Between the two groups no significant difference could be observed in four subscales of sensitivity, fear, paranoid thoughts, and psychosis. Conclusions: The results of this study showed that HIV leads to a general decline in mental disorders and efficient and effective coping styles. Patients with HIV are faced with numerous psychological and biological problems which make them different from other people. In general, social and psychological factors are involved in building and creating this condition. The person's personal and social problems will increase after he is infected with HIV. Taking measures to prevent the spread of the disease, as well as medical, psychological and social work to reduce disease progression and greater consistency can be effective in helping people with this disease
