“…The formalism developed in section 2 has been applied to a GaAs-QW, which is parameterized in terms of m * = 0.068 m e and ε 0 = 12.0 [27,28]. Before discussing our results, we ensure that the formalism developed in section 2 is correct and conforms to the requirement of the conservation laws: p − p = q and hω = ξ p − ξ p .…”

The structure factor, pair distribution function, screened impurity potential, density of screening charge, and exchange and screened exchange energies have been theoretically investigated for a semiconductor quantum wire using an improved random phase approximation that takes into account the local field corrections within the Hubbard approximation. Our approach enabled us to obtain approximate analytical results on some of the aspects and to greatly simplify the computation task on others. However, computed results from our simple approach show very good agreement with those obtained by performing cumbersome numerical solutions for the structure factor, density–density response function and the static local field corrections, within the Singwi–Tosi–Land–Sjölander approximation. Our investigations suggest that: (i) the magnitude of the screened impurity potential and the average distribution of electrons about an electron at larger distances are enhanced on reducing the width of quantum wire, and (ii) the exchange interactions strengthen on narrowing the quantum wire and on increasing the carrier density. Friedel oscillations are seen in both our computed screened potential and the density of screening charge.

“…The V 0 (q) given by equation ( 7) has also been used to investigate properties of 1D electron gas [25,28]. The integrand of equation ( 7) diverges logarithmically at the upper limit when q = 0 and at the lower limit for q → 0.…”

“…28 Studies like Oberai et al, 18 Shah et al 29 and Sharma B. 30 showed effective role of homoeopathy – Phosphorus in management of fibroids but no study was found illustrating role of homoeopathy in GBP even after intensive search in PubMed, Google Scholar, Research Gate net, AYUSH Research Portal. Homoeopathy helped in reducing her anxiety and fear as well.…”

Uterine fibroids are benign growths in female reproductive system. The presentation of uterine fibroid varies, if it is symptomatic; it may include abnormal uterine bleeding or abdominal pressure and heaviness distressing the patient both physically and mentally. A case of a female patient aged 45 years with prolonged uterine bleeding for 10 to 12 days and pain in lower abdomen for 1 year is reported here. Imaging study showed multiple uterine fibroids with grade II fatty liver and gallbladder polyps. Constitutional homoeopathic medicine Phosphorus was prescribed. This case report is an example of speedy recovery by homoeopathy as evident from decrease in symptoms (visual analogue score) and ultrasonography of abdomen report which shows not only the regression of fibroids but also disappearance of grade II fatty liver and gallbladder polyps within 2 months of treatment. Assessment of the causal attribution of the outcomes of this treated case to the homoeopathic intervention was done using Modified Naranjo Criteria and ‘definite’ association was found.

“…Few case reports and observational studies performed with homoeopathic intervention on uterine fibroid as the main treatment protocol showed beneficial effects. 12 13 14 15 An elaborated clinical trial 16 was conducted to evaluate effectiveness of homoeopathic medicines in fifty millesimal potency vis-a-vis Centesimal potencies in patients suffering from uterine fibroids it was found that irrespective of the potency scale the homeopathic medicine showed considerable reversal of the symptoms and improvement in the quality of life. In this context, the present case report, presenting menstrual complaints due to fibroid uterus managed with individualised homoeopathic medicines, emphasises the positive role of homoeopathy, one of the most popular alternative therapies in the management of fibroid uterus.…”

Uterine fibroids are common findings in women and represent benign smooth muscle tumours of the uterus. These tumors are very frequently encountered in clinical practice. Homeopathy offers a more favourable response to such conditions in addition to surgical interventions. A 30-year-old female patient visited our outpatient department with complaints of dyspareunia, which is characterized by painful sexual intercourse and abdominal distension. Ultrasonography confirmed her diagnosis of uterine fibroids. Following comprehensive case assessment and repertorization, the patient was initially prescribed individualized homeopathic medicine Natrum muriaticum 200c, followed by other medications as needed. Within approximately a year of homeopathic treatment, the patient's condition began to improve. The Modified Naranjo Criteria for Homeopathy (MONARCH) tool was employed to evaluate the causal relationship between homeopathic intervention and clinical outcome. A MONARCH score of +7 indicated that the clinical improvement was likely attributed to the homeopathic treatment, which aligns with ultrasonographic findings obtained before and after treatment. This case study underscores the effectiveness of tailored homeopathic treatment for uterine fibroids. However, more studies and evidence-based clinical verification are necessary to establish the efficacy of homeopathy in such cases.
